# Do Freelancers Need to File Quarterly with HMRC from April 2026? MTD Rules Explained for Sole Traders Last updated: 23 October 2026 Yes, from April 2026, UK sole traders and landlords with a gross income exceeding £50,000 will be required to submit quarterly digital updates to HMRC under the Making Tax Digital for Income Tax Self Assessment (MTD ITSA) rules, moving away from a single annual Self Assessment tax return. This threshold will reduce to £30,000 in April 2027. ## Understanding the Shift to Quarterly Reporting for Sole Traders For decades, the UK's Self Assessment system has required sole traders and landlords to file a single annual tax return, typically by 31 January following the end of the tax year. This familiar rhythm is set to undergo a significant transformation with the phased introduction of Making Tax Digital for Income Tax Self Assessment (MTD ITSA). This initiative, a cornerstone of HMRC's strategy to modernise the tax system, will mandate eligible individuals to maintain digital records and submit regular quarterly summaries of their income and expenses. The first wave of this change will impact sole traders and landlords with a gross income of over £50,000, who must comply from April 2026. A year later, in April 2027, the threshold will drop to £30,000, bringing many more freelancers, consultants, and small business owners into the MTD ITSA regime. This shift from annual to quarterly reporting represents a fundamental change in tax compliance, demanding more frequent engagement with financial records and the use of MTD-compatible software. While initially seeming like an increased burden, MTD ITSA aims to reduce errors, provide a more real-time view of tax liabilities, and ultimately simplify the tax process for businesses integrated with digital accounting solutions. This comprehensive guide will explain who is affected, what the new requirements entail, how to prepare, and how to navigate the broader Self Assessment landscape in light of these upcoming changes. ## Who Needs to File Quarterly with HMRC from April 2026? The requirement to file quarterly updates with HMRC from April 2026 specifically targets sole traders and landlords under the Making Tax Digital for Income Tax Self Assessment (MTD ITSA) regime. This is a significant departure from the traditional annual Self Assessment tax return and will affect a substantial number of self-employed individuals and property owners across the UK. ### The £50,000 Gross Income Threshold From **April 2026**, MTD ITSA becomes mandatory for: - **Sole traders** whose gross income from their trade or business exceeds **£50,000** in a tax year. - **Landlords** whose gross income from their property business exceeds **£50,000** in a tax year. - Individuals who are both sole traders and landlords, where their combined gross income from all businesses and properties exceeds **£50,000**. It is crucial to understand that this threshold refers to **gross income**, not profit. Gross income is the total amount earned before any expenses are deducted. Many sole traders with substantial turnover but modest profits may find themselves mandated under MTD ITSA. ### The £30,000 Gross Income Threshold The second phase of MTD ITSA implementation will occur from **April 2027**. From this date, the mandatory requirement will extend to: - **Sole traders** whose gross income from their trade or business is between **£30,000 and £50,000** in a tax year. - **Landlords** whose gross income from their property business is between **£30,000 and £50,000** in a tax year. - Individuals with combined gross income from all businesses and properties between **£30,000 and £50,000**. This phased approach means that businesses with higher incomes will be the first to transition, followed by those in the mid-income bracket. ### How to Determine Your Gross Income for MTD ITSA To determine if you fall within the MTD ITSA thresholds, you should calculate your total gross income from all relevant sources for a tax year. - **For sole traders:** This includes all turnover from sales of goods or services, fees, commissions, and any other business receipts. - **For landlords:** This includes all rent received from all properties, before deducting any expenses like mortgage interest, agent fees, or repairs. HMRC will use your income from the previous tax year to determine if you meet the threshold for the upcoming MTD ITSA reporting period. For example, to determine if you are mandated from April 2026, HMRC will look at your gross income for the 2024/25 tax year. ### Who is NOT Immediately Affected? - **Businesses with gross income under £30,000:** As of the current announcements, there is no confirmed date for mandating MTD ITSA for those with gross income below £30,000. However, these businesses can choose to opt in voluntarily if they wish to benefit from digital record keeping and quarterly updates. - **Partnerships:** General partnerships are not currently mandated for MTD ITSA, but individuals within partnerships who also operate as sole traders or landlords may be affected by the rules for their individual income. - **Limited Companies:** Limited companies are subject to MTD for VAT, but MTD ITSA specifically applies to Income Tax Self Assessment, which is for individuals, not companies. Understanding these thresholds and timelines is the first critical step for sole traders and landlords to prepare for the upcoming changes to tax reporting. Failure to comply with MTD ITSA requirements once mandated can result in penalties from HMRC. ## Making Tax Digital for Income Tax Self Assessment (MTD ITSA) Explained Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is HMRC's initiative to modernise the tax system for millions of self-employed individuals and landlords. It moves away from the traditional annual Self Assessment tax return towards a fully digital system of record-keeping and more frequent reporting. ### Core Principles of MTD ITSA MTD ITSA is built around three core principles: 1. **Digital Record Keeping:** All relevant business income and expenses must be recorded digitally using MTD-compatible software. This means no more paper ledgers or manual spreadsheets for those mandated. 2. **Quarterly Updates:** Instead of one annual submission, businesses will send summaries of their income and expenses to HMRC every three months, known as 'quarterly updates'. 3. **End of Period Statement (EOPS) and Final Declaration:** At the end of the tax year, an End of Period Statement (EOPS) must be submitted to finalise the business's profits and losses. This is followed by a Final Declaration, which replaces the traditional Self Assessment tax return, incorporating all other income sources (e.g., employment, savings) and claiming any allowances or reliefs. ### The MTD ITSA Reporting Cycle The MTD ITSA reporting cycle is structured around quarterly periods, with submission deadlines shortly after each period ends. #### Quarterly Reporting Periods and Deadlines For a standard tax year running from 6 April to 5 April, the quarterly periods and their respective submission deadlines are: | Reporting Period | Period End Date | Submission Deadline | | :--------------- | :-------------- | :------------------ | | Quarter 1 | 5 July | 5 August | | Quarter 2 | 5 October | 5 November | | Quarter 3 | 5 January | 5 February | | Quarter 4 | 5 April | 5 May | These quarterly updates are summaries of income and expenses, not a full tax calculation. They provide HMRC and the taxpayer with an estimated tax position throughout the year, allowing for better tax planning and budgeting. #### End of Period Statement (EOPS) After the fourth quarterly update for the tax year, an End of Period Statement (EOPS) must be submitted for each business or property income source. This statement allows for any necessary accounting adjustments (e.g., accruals, prepayments, stock valuations, capital allowances) to be made, finalising the taxable profit or loss for that specific business or property income. The deadline for the EOPS is **31 January** following the end of the tax year. #### Final Declaration The Final Declaration is the last step in the MTD ITSA process and replaces the annual Self Assessment tax return. It consolidates all income sources, including: - Finalised business profits (from EOPS). - Other income (e.g., employment, dividends, savings interest, foreign income). - Claims for personal allowances and reliefs. - Any capital gains. The Final Declaration calculates the individual's total tax liability for the year. The deadline for the Final Declaration is also **31 January** following the end of the tax year. ### Benefits of MTD ITSA While the transition requires adaptation, MTD ITSA offers several potential benefits: - **Reduced Errors:** Digital record keeping and automated submissions can minimise manual data entry errors. - **Real-Time View:** Quarterly updates provide a more up-to-date estimate of tax liability, helping businesses budget and plan for tax payments. - **Increased Efficiency:** Integration with MTD-compatible software can streamline accounting processes and reduce time spent on administrative tasks. - **Improved Compliance:** A clearer picture of tax obligations throughout the year can help businesses stay on top of their tax affairs. ### Challenges and Considerations - **Initial Setup:** Businesses will need to invest time in selecting and implementing MTD-compatible software and adapting to digital record-keeping practices. - **Increased Frequency of Reporting:** While the actual data submitted quarterly is less detailed than an annual return, the increased frequency demands more regular engagement with financial records. - **Learning Curve:** There may be a learning curve for businesses unfamiliar with digital accounting software. AccountsOS is designed to help sole traders navigate these changes, providing MTD-compatible software that simplifies digital record keeping and quarterly submissions. ## Preparing for Making Tax Digital for Income Tax Self Assessment (MTD ITSA) The introduction of MTD ITSA from April 2026 marks a pivotal change for many sole traders and landlords. Proactive preparation is key to a smooth transition and ensuring compliance. Even if you are not mandated until April 2027 or later, starting early will provide a significant advantage. ### 1. Understand Your Mandation Date First, identify when MTD ITSA will become mandatory for you. - **April 2026:** If your gross income from all businesses and properties was over £50,000 in the 2024/25 tax year. - **April 2027:** If your gross income from all businesses and properties was between £30,000 and £50,000 in the 2025/26 tax year. - **Voluntary:** If your gross income is below £30,000, you can choose to opt in voluntarily. Knowing your specific start date allows you to plan your preparations effectively. ### 2. Choose MTD-Compatible Software This is arguably the most critical step. MTD ITSA mandates the use of 'functional compatible software' for digital record keeping and submitting updates to HMRC. - **Research options:** Explore various MTD-compatible accounting software solutions available in the market. Consider factors like ease of use, features, cost, and customer support. - **AccountsOS:** As an MTD-compatible solution, AccountsOS is designed to help sole traders manage their income and expenses digitally, prepare quarterly updates, and submit their End of Period Statements and Final Declarations to HMRC seamlessly. - **Bridging Software:** If you currently rely on spreadsheets for your records, you might consider 'bridging software'. This links your spreadsheet data to HMRC's MTD system. However, for long-term efficiency and full compliance, a comprehensive MTD-compatible accounting package is generally recommended. ### 3. Digitalise Your Record Keeping The core of MTD ITSA is digital record keeping. - **Move away from paper:** Start scanning and storing all your invoices, receipts, and other financial documents digitally. - **Automate data entry:** Utilise features in accounting software that allow for bank feeds, automatic categorisation of transactions, and receipt capture via mobile apps. This reduces manual input and potential errors. - **Categorise transactions:** Ensure you understand and correctly categorise your income and expenses according to HMRC's allowable expense rules. This is crucial for accurate quarterly updates and the EOPS. - **Keep records of all income:** This includes all sales, fees, and other business receipts. For cash-basis accounting, record income when received. - **Keep records of all expenses:** This includes all business purchases, travel costs, office expenses, and other outgoings. For cash-basis accounting, record expenses when paid. ### 4. Understand Quarterly Reporting Familiarise yourself with the new reporting cycle and deadlines. - **Regular review:** Instead of an annual scramble, you'll need to review your financial records every three months. - **Budget for tax:** The quarterly updates will provide a more accurate, real-time estimate of your tax liability, allowing you to set aside funds regularly for your tax bill. This can help avoid large, unexpected payments at year-end. - **Seek guidance:** If unsure, consult with an accountant or tax advisor who is knowledgeable about MTD ITSA. They can help you understand the specific requirements for your business and ensure your software is correctly set up. ### 5. Review Your Accounting Period Most sole traders currently use the tax year (6 April to 5 April) as their accounting period. This aligns well with MTD ITSA's quarterly reporting periods. If your business currently uses a different accounting period, you may need to adjust it to align with the tax year to simplify MTD ITSA compliance. This is known as 'period of account alignment'. HMRC provides guidance on making this change. ### 6. Consider Voluntary Participation Even if you are not yet mandated, consider opting in to MTD ITSA voluntarily. This allows you to familiarise yourself with the new system at your own pace, iron out any issues, and get comfortable with the software before it becomes compulsory. Many businesses find that digitalising their records and using accounting software improves efficiency and provides better financial insights, regardless of MTD. By taking these steps, sole traders can proactively prepare for MTD ITSA, transforming a compliance challenge into an opportunity for improved financial management and efficiency. ## Understanding Self Assessment for UK Sole Traders (Pre-MTD context) While MTD ITSA introduces new reporting requirements, the underlying principles of Self Assessment for sole traders remain crucial. MTD ITSA is a digital method of fulfilling your Self Assessment obligations, not a replacement for them. Understanding the core Self Assessment rules is essential for all sole traders, regardless of their MTD ITSA mandation date. Self Assessment is the system HMRC uses to collect Income Tax from individuals who earn income that is not taxed at source, such as sole traders, partners in partnerships, and those with rental income or significant investment income. If you operate as a sole trader in the UK, understanding your Self Assessment obligations is paramount to ensure compliance, avoid penalties, and effectively manage your tax affairs. ### Who Needs to File a Self Assessment Tax Return? While the headline often focuses on sole traders earning over £1,000, the requirement to file a Self Assessment tax return extends to many other individuals in the UK. It is crucial to understand all the potential triggers to avoid penalties for non-compliance. - You were self-employed as a 'sole trader' and earned more than £1,000 in the tax year (before taking off any tax-free allowances or expenses). - You were a partner in a business partnership. - You received income from renting out property. - You received tips and commission. - You received income from savings, investments, or dividends (if not taxed at source or above certain thresholds). - You had foreign income (even if taxed abroad). - You had capital gains (e.g., from selling shares or a second home). - You received income from a trust. - You or your partner received Child Benefit and your income was over £50,000. - You need to claim tax reliefs or expenses. - You received any other untaxed income. - You wish to make voluntary National Insurance contributions. **The Trading Allowance:** Since April 2017, there has been a £1,000 'trading allowance' for individuals with self-employment income. If your gross income from self-employment is £1,000 or less in a tax year, you do not need to register for Self Assessment or pay tax on this income, unless you choose to claim expenses or other tax reliefs. This simplifies tax for hobbyists or those with very small side incomes. If your gross income is over £1,000, you must register and file. #### Specific Scenarios and Clarifications Let's delve deeper into some common situations that might require you to file, even if you do not consider yourself a full-time sole trader. **Self-Employment and Side Hustles:** Any income from providing goods or services, even on an infrequent basis, counts as self-employment. This includes freelance work, consulting, selling crafts online, or driving for a ride-sharing app. If the gross income from these activities exceeds £1,000 in a tax year (6 April to 5 April), you are obligated to register for Self Assessment. It is your responsibility to track this income, even if platforms or clients do not deduct tax at source. **Rental Property Income:** If you receive income from renting out property, you will almost certainly need to complete a Self Assessment tax return. This applies whether you rent out a spare room, a holiday let, or multiple properties. Even if your property income is covered by the £1,000 property allowance, you may still need to declare it if your total gross property income is over £2,500. It is crucial to report all rental income and claim all allowable expenses to calculate your true taxable profit. **High Income and Child Benefit Charge:** If you or your partner receive Child Benefit and either of your individual incomes exceeds £50,000 in a tax year, you will be liable for the High Income Child Benefit Charge (HICBC). This charge effectively claws back some or all of the Child Benefit received. To pay this charge, you must file a Self Assessment tax return. The charge increases incrementally, and by the time your income reaches £60,000, the Child Benefit is entirely repaid through the tax charge. **Untaxed Savings, Investments, and Dividends:** While most savings interest is paid gross (without tax deducted), banks and building societies usually report it to HMRC. However, if your untaxed interest or dividend income is substantial and exceeds your available allowances (such as the Personal Savings Allowance or Dividend Allowance), you might need to file a Self Assessment return to pay the tax due. For instance, the Dividend Allowance is £500 for the 2024/25 tax year. **Foreign Income:** If you are a UK resident and have income from abroad, you generally need to declare it to HMRC, even if it has already been taxed in another country. This includes foreign rental income, overseas pensions, or income from foreign investments. You may be able to claim Foreign Tax Credit Relief to prevent being taxed twice, but this requires a Self Assessment return. **Capital Gains:** Selling assets like shares, a second home, or other valuable items can result in a capital gain. If your total capital gains exceed the annual exempt amount (e.g., £3,000 for 2024/25), or if you sell a residential property in the UK, you will need to report this via Self Assessment. For residential property sales, a separate 'Capital Gains Tax on UK property' return must often be filed and tax paid within 60 days of completion. It is always better to check with HMRC or a tax professional if you are unsure about your filing obligations. Failure to register and file when required can lead to penalties, even if you owe no tax. ## Registering for Self Assessment Once you have determined that you need to file a Self Assessment tax return, the next crucial step is to register with HMRC. This process establishes your Unique Taxpayer Reference (UTR) and informs HMRC of your self-employment status. ### When to Register The deadline to register for Self Assessment is **5 October** after the end of the tax year in which you started self-employment or first met the criteria for filing. **Example:** If you started self-employment on 12 June 2026 (during the 2026/27 tax year), you must register by 5 October 2027. It is highly recommended to register as soon as possible after you start trading. Do not wait until the deadline, as HMRC will need to send you a UTR, which can take several weeks. You cannot file a tax return without your UTR. ### How to Register The registration process varies slightly depending on whether you have filed a Self Assessment return before. #### If you've never sent a tax return before: 1. Go to the [HMRC website](https://www.gov.uk/register-for-self-assessment) and follow the instructions to register as self-employed. 2. You will need your National Insurance number, the date you started self-employment, and your business details. 3. HMRC will then send you a letter with your 10-digit Unique Taxpayer Reference (UTR). This usually arrives within 10 working days, but can take longer. Keep it safe, as you will need it for all future Self Assessment interactions. 4. After receiving your UTR, HMRC will send you another letter with an activation code to set up your online Self Assessment account. This code is essential if you plan to file your return online via HMRC's portal. #### If you've sent a tax return before: If you have previously filed a Self Assessment return but have recently become self-employed or started receiving new types of untaxed income, you usually do not need to re-register for Self Assessment. Instead, you simply need to inform HMRC of your new income sources. You can do this by: - Logging into your existing online Self Assessment account and updating your details. - Calling the Self Assessment helpline. HMRC will then ensure that your next tax return includes the relevant sections for your new income streams. ### What Happens if You Miss the Registration Deadline? Missing the 5 October registration deadline can result in a penalty. While HMRC may be lenient if it's your first time and you register soon after, it is best to avoid this situation. The penalty for late registration can be £100 or more, depending on how late you are. **Important:** Do not delay registration. Even if you believe you will not owe any tax due to low income or high expenses, the obligation to register and file still stands if you meet the criteria. ## What Income to Declare on Your Self Assessment Return A Self Assessment tax return is designed to capture all your taxable income from various sources, not just your self-employment earnings. It is vital to declare everything accurately to avoid problems with HMRC. Under MTD ITSA, this information will be compiled from your quarterly updates, EOPS, and other digital records into your Final Declaration. ### Self-Employment Income This is the core of most sole traders' Self Assessment returns. You must declare all gross income received from your trade, profession, or vocation. This includes: - Sales of goods or services. - Fees for consultancy or freelance work. - Income from online platforms (e.g., Etsy, eBay, Fiverr, Upwork, Airbnb, Uber). - Any other earnings generated by your business activities. It is important to declare the gross income before any expenses are deducted. The expenses will be claimed separately to arrive at your taxable profit. ### Other Income Sources Beyond self-employment, your Self Assessment return will ask you to declare other forms of income, which may include: #### Employment Income If you are a sole trader but also have a PAYE job, you need to report your employment income, usually as shown on your P60. HMRC will use this information to calculate your total income and ensure you are taxed correctly across all sources. #### Rental Income Income from any property you rent out, whether residential or commercial, needs to be declared. This includes profits from holiday lets. You will report your gross rental income and then deduct allowable property expenses to calculate your taxable property profit. #### Savings and Investment Income This includes: - **Interest from banks and building societies:** While the Personal Savings Allowance (PSA) means many people pay no tax on savings interest, if your interest exceeds your PSA, or if you are a higher or additional rate taxpayer, you will need to declare it. - **Dividends from UK companies:** If you receive dividends beyond the Dividend Allowance, these must be declared. The Dividend Allowance is £500 for the 2024/25 tax year. - **Income from trusts or settlements.** - **Gains from life insurance policies.** #### Foreign Income As mentioned earlier, income from overseas sources, such as foreign property, pensions, or investments, must be declared. You will need to specify the type of income and the country it came from. #### Capital Gains Profits made from selling assets, such as shares not held in ISAs, second homes, or other chargeable assets, are subject to Capital Gains Tax and must be reported on your Self Assessment if they exceed the annual exempt amount (e.g., £3,000 for 2024/25). #### Other Taxable Income This can be a catch-all for various other income types, including: - Any untaxed income not covered elsewhere. - Certain benefits (e.g., State Pension, if your other income is high). - Income from a trust or settlement. Thorough record-keeping is essential for accurately declaring all your income. Keep track of all invoices, receipts, bank statements, and any other documentation related to your earnings. Under MTD ITSA, these records must be kept digitally. ## Allowable Expenses for Sole Traders One of the most significant advantages of being a sole trader is the ability to deduct 'allowable expenses' from your gross income to reduce your taxable profit. This directly lowers your Income Tax and Class 4 National Insurance contributions. An expense is allowable if it is incurred 'wholly and exclusively' for the purposes of your trade. Under MTD ITSA, these expenses must be recorded digitally. ### General Principle: Wholly and Exclusively This is the golden rule for allowable expenses. If an expense has a dual purpose (partly for business, partly for personal use), only the business portion can be claimed. For example, if you use your personal mobile phone 50% for business, you can claim 50% of the bill. It is important to have a reasonable method for apportioning such costs and to keep records to justify your claim. ### Common Allowable Expense Categories Below is a detailed breakdown of common categories of allowable expenses for sole traders. #### Office Costs - **Rent, rates, utility bills (heat, light, power)** for business premises. If you operate from a dedicated office or workshop, these costs are fully allowable. - **Office supplies:** Stationery, printer ink, postage, small office equipment (e.g., calculators, staplers). - **Phone, mobile, and internet bills:** If used for business, a proportion can be claimed. Dedicated business lines can be fully claimed. - **Cleaning and maintenance of business premises:** Costs associated with keeping your workspace clean and in good repair. - **Small equipment:** Items like printers, scanners, or software licenses under a certain value (often expensed if under £1,000, or claimed via capital allowances for larger items). #### Travel Costs - **Fuel, parking, train, bus, or taxi fares** for business journeys. This includes travel to client meetings, suppliers, or business events. - **Hotel rooms and meals** on overnight business trips. These must be reasonable and incurred solely for business purposes. - **Vehicle insurance, repairs, servicing, and breakdown cover** for business vehicles. If you use your personal car for business, you can claim a proportion of these costs or use simplified expenses (mileage allowance). - **Hire charges** for vehicles or equipment used exclusively for business. Travel expenses must be 'wholly and exclusively' for business purposes. Commuting from home to a regular workplace is generally not allowable, as it is considered ordinary domestic travel. #### Marketing and Advertising - **Website costs and domain names:** Development, hosting, and maintenance of your business website. - **Social media advertising:** Paid campaigns on platforms like Facebook, Instagram, or LinkedIn. - **Printed advertising:** Flyers, brochures, business cards. - **Directory listings:** Costs for appearing in online or print business directories. - **Promotional materials:** Branded merchandise or giveaways. Any costs incurred to promote your business and attract customers are typically allowable. #### Professional Fees - **Accountant's fees:** For preparing your business accounts, Self Assessment tax returns, and general tax advice. - **Legal fees:** For business contracts, intellectual property protection, or resolving business disputes (not for buying property or personal legal matters). - **Consultancy fees:** Payments to consultants for business advice or specialised services. Fees for professional advice related to your business operations are generally deductible. #### Training and Subscriptions - **Training courses:** Directly related to improving skills for your current business. For example, a web designer taking a course on a new coding language. - **Professional body subscriptions:** Fees to maintain membership in a professional organisation relevant to your trade. - **Trade magazine subscriptions:** Publications relevant to your industry. Training must be for skills used in your existing business, not for acquiring new qualifications to start a different business. #### Financial Costs - **Bank charges and interest on business loans:** Fees for your business bank account and interest paid on loans taken out for business purposes. - **Credit card charges:** Interest and fees on business credit cards. - **Insurance for your business:** E.g., public liability, professional indemnity, contents insurance for business equipment. Interest on personal loans used for business is not allowable. Bank charges for business accounts are usually deductible. #### Staff Costs (if applicable) - **Salaries and wages:** If you employ staff. - **Employer's National Insurance contributions:** Paid on employee salaries. - **Pension contributions:** For employees, paid into a workplace pension scheme. - **Staff training costs:** To improve employee skills. If your sole trader business employs others, these costs are allowable. Your own drawings or salary as a sole trader are not an allowable expense, as you are not an employee of your own sole proprietorship. #### Capital Allowances - **Plant and machinery:** This includes items like computers, vehicles, tools, and office furniture that are purchased for business use and expected to last more than two years. - **Fixtures and fittings:** For business premises. Instead of deducting the full cost of large assets in the year of purchase, you claim capital allowances over several years. The Annual Investment Allowance (AIA) allows you to deduct the full value of most assets (up to £1 million) in the year of purchase, effectively treating it as an expense for tax purposes. #### Pre-Trading Expenses - **Expenses incurred up to 7 years before you started trading:** These can be treated as if they were incurred on the first day of trading, allowing you to claim them against your first year's profits. Examples include market research, advertising, or office setup costs incurred before your business officially launched. ### Working from Home: Simplified Expenses vs. Actual Costs If you work from home, you have two main options for claiming expenses: - **Simplified Expenses:** HMRC offers flat rates for using your home as an office. For example, for 2026/27, if you work 25-50 hours a month from home, you can claim £10 per month. For 51-100 hours, it's £18 per month, and for 101+ hours, it's £26 per month. This is simpler as you do not need to calculate specific proportions of bills. This covers additional costs for heating, electricity, and broadband. - **Actual Costs:** You can calculate the actual proportion of your household bills (e.g., electricity, gas, internet, council tax, mortgage interest/rent) that relates to your business use. This usually involves calculating the number of rooms used for business and the time spent working in them. This method can sometimes result in a higher claim but requires more detailed record-keeping and a robust method for apportionment. ### What is NOT an Allowable Expense? It is equally important to know what you cannot claim: - **Personal drawings:** Money you take out of the business for personal use is not an expense. - **Personal living costs:** Your personal rent, mortgage repayments (capital portion), food, and non-business clothing are not allowable. - **Fines and penalties:** Parking fines, speeding tickets, or HMRC penalties are not deductible. - **Entertaining clients:** Generally, entertaining clients is not an allowable expense, although staff entertaining may be allowable in some cases (e.g., annual events up to £150 per head). - **Depreciation:** While large assets are not expensed directly, you claim capital allowances instead of depreciation. - **Clothing:** Unless it is protective clothing or a uniform specific to your trade, everyday clothing is not allowable. Accurate record-keeping of all income and expenses is paramount. Keep all receipts, invoices, and bank statements. Accounting software like AccountsOS can significantly simplify this process by categorising transactions automatically and storing digital copies of your documents, which is essential for MTD ITSA compliance. ## Calculating Your Taxable Profit Your Income Tax and Class 4 National Insurance contributions are not calculated on your total income, but on your **taxable profit**. This is the figure that remains after you have deducted all your allowable business expenses from your gross business income. Under MTD ITSA, this calculation will be performed as part of your End of Period Statement (EOPS) and Final Declaration. ### The Calculation Formula Gross Business Income minus Allowable Business Expenses equals Taxable Business Profit. ### What to Include in Gross Business Income This includes all money, goods, or services received by your business. For cash-basis accounting (which most sole traders use if their turnover is below £150,000), you record income when it is received, not when invoiced. - Cash sales. - Bank transfers from clients. - Payments received via online platforms (e.g., PayPal, Stripe, card readers). - Value of goods or services received in lieu of cash (barter transactions). - Any grants or subsidies specifically for your business. ### Accounting Methods: Cash Basis vs. Traditional Accounting (Accruals Basis) Most sole traders can use the 'cash basis' accounting method if their business turnover is £150,000 or less. For MTD ITSA, HMRC generally expects businesses to use the cash basis unless they choose otherwise. - **Cash Basis:** You record income when you actually receive it and expenses when you actually pay them. This is simpler and often preferred by smaller businesses because it aligns with cash flow. You do not need to account for debtors (money owed to you) or creditors (money you owe). - **Traditional Accounting (Accruals Basis):** You record income when you invoice it or earn it (even if not yet paid) and expenses when you incur them (even if not yet paid). This provides a more accurate picture of financial performance over a period, regardless of when cash changes hands. This is generally used by larger businesses or those with complex stock management. You choose which method to use when you complete your Self Assessment tax return (or EOPS under MTD ITSA). Once chosen, it is usually best to stick with it for consistency. ### Worked Example: Calculating Taxable Profit Let's consider a freelance graphic designer, Alex, for the tax year 2026/27. He uses the cash basis of accounting. | Alex's Financials for 2026/27 | Amount (£) | | :---------------------------- | :--------- | | Gross Income from Clients | 45,000 | | **Allowable Expenses:** | | | Software Subscriptions | 800 | | Home Office Simplified Expenses (101+ hrs/month) | 312 (£26 x 12 months) | | Professional Training Course | 600 | | New Laptop (Capital Allowance claimed) | 1,200 | | Travel for Client Meetings | 250 | | Accountant's Fees | 400 | | **Total Allowable Expenses** | **3,562** | | **Alex's Taxable Business Profit (£45,000 - £3,562)** | **41,438** | Alex's taxable business profit of £41,438 will then be used to calculate his Income Tax and Class 4 National Insurance contributions. This figure will be combined with any other taxable income (e.g., PAYE salary) to determine his overall tax liability. ### Losses If your allowable expenses exceed your gross income, your business has made a loss. You do not pay tax on a loss, but you can usually claim 'loss relief'. This allows you to carry the loss forward to offset against future profits from the same business, or in some cases, carry it back to offset against profits from previous years. This is an important relief that can reduce your tax bill in profitable years. The method of claiming loss relief will be detailed in your EOPS. ## National Insurance Contributions (NICs) for Sole Traders As a sole trader, you are typically liable for two types of National Insurance Contributions: Class 2 and Class 4. These contributions are crucial as they count towards your entitlement to certain state benefits, including the State Pension, Maternity Allowance, and Bereavement Support Payment (for Class 2). ### Class 2 National Insurance - **Threshold:** Profits over £6,725 - **Rate:** Voluntary from April 2024 (previously £3.45 per week) Historically, Class 2 NICs were a fixed weekly payment, compulsory for profits over the Small Profits Threshold. From **April 2024**, if your profits are above £6,725 (the Lower Profits Threshold for 2024/25, expected to remain for 2026/27), your Class 2 NI contributions are treated as paid automatically, and you do not need to make active payments. This means you will still build up State Pension entitlement without having to pay Class 2. If your profits are below £6,725, you can choose to pay Class 2 NICs voluntarily to protect your state pension and other benefits. For the 2024/25 tax year, the voluntary rate is £3.45 per week. The changes from April 2024 significantly simplify the process for many sole traders, removing the need for active payment but retaining the benefit accrual for those above the profit threshold. For those below, voluntary payments are key to protecting their benefit record. ### Class 4 National Insurance Class 4 NICs are calculated as a percentage of your taxable business profits above certain thresholds. Unlike Class 2, Class 4 contributions do not count towards State Pension entitlement, but they are a compulsory tax on your profits. The rates have seen significant reductions in 2024, making self-employment more attractive from a tax perspective. - **Class 4 National Insurance: profits between £12,570 and £50,270** - **Rate:** 6% (from April 2024, expected for 2026/27) This applies to profits within this band. This rate was reduced from 9% to 8% in January 2024, and then further to 6% from April 2024. - **Class 4 National Insurance: profits over £50,270** - **Rate:** 2% (from April 2024, expected for 2026/27) This applies to profits above the higher rate threshold. This rate was reduced from 2% to 2% in January 2024 and remains at 2% from April 2024. The Lower Profits Threshold for Class 4 NICs is aligned with the Personal Allowance for Income Tax, which is £12,570 for 2024/25. The Upper Profits Limit is £50,270 for 2024/25. ### Worked Example: National Insurance Calculation Using Alex's taxable business profit of £41,438 for the 2026/27 tax year (assuming rates and thresholds remain as of April 2024): | Alex's National Insurance, 2026/27 | Amount (£) | | :------------------------------- | :--------- | | Taxable Profit | 41,438 | | Class 2 NICs (Profits > £6,725) | 0 (treated as paid) | | Class 4 NICs on profits £12,570 - £41,438 | 1,732.08 | | **Calculation:** (£41,438 - £12,570) x 6% = £28,868 x 0.06 | | | **Total National Insurance** | **1,732.08** | This demonstrates how Class 4 NICs are applied once your profits exceed the lower threshold. ## Income Tax Rates and Bands for Sole Traders Your taxable business profit, along with any other income you declare, forms your total taxable income. This total is then subject to UK Income Tax rates. The UK operates a progressive tax system, meaning you pay different rates on different portions of your income. Income Tax is a significant part of your overall tax liability as a sole trader. ### Income Tax Bands (2024/25, expected 2026/27) These rates apply to earnings in England, Wales, and Northern Ireland. Scotland has slightly different rates and bands. The thresholds have been frozen until April 2028. | Band | Income | Rate | Description clear out the re-use area after use clear as possible.

Yes, if your gross income from self-employment and/or property exceeds £50,000 in a tax year, you will be mandated to submit quarterly digital updates to HMRC under Making Tax Digital for Income Tax Self Assessment (MTD ITSA) from April 2026. This threshold drops to £30,000 from April 2027. ### What is the 'gross income' threshold for MTD ITSA? The initial threshold for MTD ITSA is £50,000 gross income from all businesses and properties, starting April 2026. This means your total earnings before any expenses are deducted. The threshold will then decrease to £30,000 gross income from April 2027. ### What happens if I miss an MTD ITSA quarterly submission deadline? HMRC is introducing a new penalty system for MTD ITSA, which will involve points-based penalties for late submissions. Accumulating points can lead to financial penalties, so it's crucial to meet all quarterly deadlines. ### What kind of software do I need for MTD ITSA? You will need 'functional compatible software' that can keep digital records of your income and expenses and send quarterly updates directly to HMRC. This can be dedicated accounting software like AccountsOS, or in some cases, bridging software that connects spreadsheets to HMRC. ### Will MTD ITSA replace my annual Self Assessment tax return entirely? MTD ITSA will replace the traditional Self Assessment tax return process. Instead of one annual return, you will submit quarterly updates, an End of Period Statement (EOPS) for each business, and a Final Declaration that consolidates all your income and claims. ### What is the difference between gross income and profit for MTD ITSA? Gross income is your total revenue before deducting any expenses. Profit is what remains after you deduct all your allowable business expenses from your gross income. MTD ITSA mandation is based on your gross income threshold. ### Can I opt out of MTD ITSA if my income is above the threshold? No, if your gross income exceeds the mandated threshold, compliance with MTD ITSA becomes compulsory. Failure to comply can result in penalties from HMRC. ### How can AccountsOS help me prepare for MTD ITSA? AccountsOS is an MTD-compatible accounting software designed to help sole traders keep digital records, automate expense categorisation, track real-time profit, and easily submit the required quarterly updates, EOPS, and Final Declarations to HMRC. ## Related guides - [Self Assessment Tax Calculator](/tools/tax-calculator) - [Guide to Allowable Expenses](/blog/allowable-business-expenses-uk) - [Understanding MTD ITSA](/making-tax-digital/income-tax) - [All Tax Deadlines](/deadlines)
