Allowable Expenses for UK Freelancers (Self Assessment)

Comprehensive guide for UK freelancers and self-employed professionals on claiming allowable expenses for Self Assessment tax returns. Reduce your tax bill legally.

Updated 23 September 202626 min read

Quick answer

UK freelancers can claim a wide range of 'wholly and exclusively' business expenses, including office costs, travel, marketing, professional fees, and capital allowances, to reduce their taxable profit and lower their Self Assessment income tax and National Insurance contributions.

UK freelancers and self-employed professionals can significantly reduce their Self Assessment tax bills by claiming legitimate business expenses. Identifying and accurately recording these costs is crucial for lowering your taxable profit and ensuring HMRC compliance.

Understanding Allowable Expenses for Self Assessment

For freelancers, consultants, sole traders, and anyone else operating as a self-employed professional in the UK, navigating the world of Self Assessment tax returns can seem daunting. One of the most crucial aspects of this process is understanding and correctly claiming allowable business expenses. These are costs that you incur "wholly and exclusively" for the purpose of your trade. By accurately deducting these expenses from your business income, you reduce your taxable profit, which in turn lowers your Income Tax and National Insurance contributions.

This comprehensive guide aims to demystify allowable expenses, providing clarity on what you can and cannot claim, along with practical examples and HMRC guidance. Proper expense management is not just about saving money; it is about ensuring compliance with HMRC rules and maintaining accurate financial records for your business. Whether you are a seasoned freelancer or just starting out, mastering your expenses is a fundamental step towards effective financial management and tax efficiency.

The information provided here is current for the 2024/2025 tax year, which runs from 6 April 2024 to 5 April 2025. Always refer to the latest HMRC guidance or consult a qualified accountant for advice specific to your circumstances, as tax rules can change.

What Exactly Are Allowable Expenses?

Allowable expenses are costs that HMRC permits you to deduct from your business income before calculating your taxable profit. The fundamental principle governing what counts as an allowable expense is that it must be incurred "wholly and exclusively" for the purpose of your trade. This means the expense should have no, or only an incidental, personal benefit.

The "Wholly and Exclusively" Rule

This is the cornerstone of expense claims for self-employed individuals. If an expense serves a dual purpose, meaning it has both a business and a personal element, it generally cannot be claimed, even if the business element is substantial. However, there are exceptions where a clear business proportion can be identified and separated.

For instance, the cost of a business-specific software subscription is wholly and exclusively for your trade. Conversely, the cost of an everyday suit, even if worn for client meetings, is not allowable because it is also suitable for personal wear. HMRC views this as having an 'unquantifiable' personal benefit.

Revenue vs. Capital Expenditure

It is important to distinguish between revenue expenditure and capital expenditure:

  • Revenue Expenditure: These are day-to-day running costs of your business, such as stationery, utility bills, or marketing. They are fully deductible against your income in the tax year they are incurred.
  • Capital Expenditure: These are costs incurred on assets that you keep for your business, such as computers, office furniture, or vehicles. You cannot deduct their full cost as a revenue expense. Instead, you claim 'capital allowances' over time, which are specific deductions that account for the depreciation of the asset.

Understanding this distinction is crucial for accurate tax reporting. We will delve into capital allowances in more detail later in this guide.

General Principles for Claiming Expenses

Beyond the "wholly and exclusively" rule, several other principles guide the claiming of allowable expenses. Adhering to these will ensure your Self Assessment tax return is accurate and robust against potential HMRC enquiries.

The Importance of Record Keeping

HMRC requires you to keep accurate records of all your business income and expenses. These records serve as evidence for your claims if HMRC decides to open an enquiry into your tax return.

What records should you keep?

  • Receipts and Invoices: For all purchases, whether digital or physical. These should clearly show the date, supplier, description of goods/services, and amount.
  • Bank and Credit Card Statements: To reconcile your business transactions.
  • Mileage Records: If claiming vehicle expenses, a detailed log of business journeys, including dates, destinations, purposes, and mileage.
  • Correspondence: Any relevant communications related to expenses, such as contracts or agreements.

You must keep your records for at least 5 years after the 31 January submission deadline for the relevant tax year. For example, for the 2024/2025 tax year, you need to keep records until at least 31 January 2031. Digital record keeping, using accounting software like AccountsOS, is highly recommended for efficiency and compliance.

Mixed-Use Assets and Apportionment

Sometimes, an asset or service is used for both business and personal purposes, but the business element can be clearly identified and quantified. In such cases, you can claim the business proportion of the expense.

Example: Mobile Phone Bill. If your monthly mobile phone bill is £50, and you estimate that 70% of your usage is for business calls and data, you can claim £35 (£50 x 70%) as an allowable expense. You should be able to justify this apportionment, for instance, by reviewing call logs or data usage.

This principle applies to various expenses, particularly those related to working from home, which we will explore in detail.

Pre-Trading Expenses

You can claim for expenses incurred before your business officially started trading, provided they meet the "wholly and exclusively" rule. HMRC allows you to claim these expenses as if they were incurred on the first day of trading. This typically applies to expenses incurred up to seven years before the start date of your business.

Example: Website Development. You spent £1,000 on developing your business website in January 2024, but your freelance business officially started trading in June 2024. This £1,000 can be treated as an allowable expense in your first tax return.

Detailed Categories of Allowable Expenses

Now, let us delve into the specific types of expenses that UK freelancers can typically claim. This section provides detailed explanations and examples for each category.

1. Office and Administrative Costs

These are the everyday costs associated with running your office or administrative tasks.

  • Rent for Business Premises: If you rent a dedicated office, workshop, or studio space, the rent is fully allowable.
  • Utilities: Electricity, gas, water, and business rates for your dedicated business premises.
  • Stationery and Office Supplies: Pens, paper, printer ink, notebooks, files, and other consumables.
  • Postage and Delivery: Costs for sending business-related mail or parcels.
  • Telephone and Internet: The business portion of your phone bills (mobile and landline) and internet connection. If you have a dedicated business line/connection, it is fully allowable.
  • Cleaning: Costs for cleaning your dedicated business premises.

Example: Internet Bill Apportionment. If your home internet bill is £40 per month and you use it 80% for your freelance work, you can claim £32 per month (£40 x 80%). Keep a record of how you determined this percentage.

2. Working from Home Expenses

Many freelancers work from home, and HMRC allows you to claim a proportion of your household costs as business expenses. You have two main options:

a. Simplified Expenses (Flat Rate)

This is the easiest method. You can claim a flat rate based on the number of hours you work from home each month.

Hours worked from home per month Monthly flat rate
25 to 50 hours £10
51 to 100 hours £18
101 hours or more £26

This rate covers increased costs for utilities (heating, electricity) and internet. You cannot claim any additional amounts for these if you use the simplified expenses. You can, however, still claim for business-specific phone calls (if separate from your personal line) and other non-utility office costs like stationery.

b. Actual Costs (Proportionate Method)

If your actual costs are higher, you can calculate the business proportion of your household expenses. This requires more detailed record keeping.

You need to calculate a reasonable proportion based on:

  • Number of Rooms: The number of rooms used for business compared to the total number of rooms in your home.
  • Time Spent: The amount of time the room is used for business compared to personal use.

Allowable costs include:

  • Heating and Lighting: A proportion of your gas and electricity bills.
  • Council Tax: A proportion of your council tax bill.
  • Mortgage Interest / Rent: A proportion of your mortgage interest (not capital repayments) or rent.
  • Home Insurance: A proportion of your home insurance.
  • Repairs and Maintenance: If a repair is specifically for your business space (e.g., fixing a desk in your office room), it is allowable. If it is for the whole house (e.g., roof repair), only a proportion may be claimed.

Worked Example: Actual Working from Home Costs. A freelancer works from a dedicated office room in their 4-room house (excluding kitchen/bathroom). Annual household expenses:

  • Electricity: £1,200
  • Gas: £800
  • Council Tax: £1,800
  • Mortgage Interest: £3,600

Calculation:

  1. Proportion of rooms: 1 business room / 4 total rooms = 25%
  2. Total annual household costs: £1,200 + £800 + £1,800 + £3,600 = £7,400
  3. Allowable expense: £7,400 x 25% = £1,850

This £1,850 can be claimed. If the room is not exclusively used for business, a further time apportionment would be needed (e.g., 50% business use of that room, so £1,850 x 50% = £925).

Important Note: Claiming a proportion of your home expenses, especially mortgage interest or rent, can potentially impact your Capital Gains Tax CGT liability if you sell your home, as the business portion might not qualify for Private Residence Relief. Consult an accountant if you are concerned about this.

3. Travel and Subsistence

Business travel expenses are generally allowable, but strict rules apply, particularly for "ordinary commuting".

a. Allowable Travel Costs

  • Fuel and Vehicle Running Costs: For journeys made for business purposes. This includes fuel, insurance, servicing, repairs, and breakdown cover.
  • Public Transport: Train, bus, tram, and plane fares for business trips.
  • Taxis: For business travel where public transport is not feasible or practical.
  • Accommodation: Hotel stays or other overnight accommodation when working away from home for business.
  • Tolls, Parking, and Congestion Charges: Incurred during business journeys.

b. Non-Allowable Travel Costs: Ordinary Commuting

Travel between your home and your regular place of work (even if that is an office you use regularly) is considered "ordinary commuting" and is generally not allowable. This applies even if your home is your primary base.

Example: Commuting. If you work from home but regularly visit a client's office every Tuesday, the travel costs to that client's office are not usually allowable if it becomes a regular, predictable pattern akin to commuting. However, if you visit a different client on an ad-hoc basis, that travel would be allowable. HMRC considers the "pattern" and "regularity" of travel.

c. Subsistence (Food and Drink)

You can claim for reasonable costs of food and drink when you are travelling for business and are away from your usual place of work for an extended period. This means costs that are over and above what you would normally spend on food and drink if you were not travelling.

Example: Business Trip Meal. If you travel to another city for a client meeting and stay overnight, the cost of your evening meal and breakfast, within reason, would be allowable. However, a lavish meal with alcohol might be challenged by HMRC.

d. Simplified Expenses for Vehicles

Instead of calculating the actual costs of fuel, insurance, servicing, etc., you can use HMRC's simplified mileage rates for cars, vans, and motorcycles.

Vehicle Type First 10,000 miles Over 10,000 miles
Cars and Vans 45p per mile 25p per mile
Motorcycles 24p per mile 24p per mile

If you use simplified expenses for your vehicle, you cannot claim capital allowances for the vehicle or any other vehicle running costs (e.g., insurance, repairs, servicing). You must keep a detailed mileage log to use this method.

Worked Example: Simplified Mileage Expenses. A freelancer drives 12,000 business miles in their car during the tax year. Calculation:

  • First 10,000 miles: 10,000 x £0.45 = £4,500
  • Remaining 2,000 miles: 2,000 x £0.25 = £500
  • Total allowable expense: £4,500 + £500 = £5,000

4. Marketing, Advertising, and Website Costs

Promoting your business is essential, and many related costs are allowable.

  • Website Costs: Domain name registration, web hosting fees, website maintenance, and minor updates are allowable. Significant new website development may be treated as capital expenditure.
  • Online Advertising: Costs for Google Ads, social media advertising (Facebook, Instagram, LinkedIn), and other digital marketing campaigns.
  • Print Advertising: Flyers, brochures, business cards, advertisements in magazines or newspapers.
  • Public Relations (PR): Fees paid to PR agencies or consultants.
  • Networking Events and Trade Fairs: Entry fees, stand costs, and related travel for events specifically aimed at promoting your business.

Caution: Business Entertainment. While networking event fees are allowable, any business entertainment provided at these events, such as buying clients drinks or meals, is generally not allowable.

5. Professional Fees and Insurance

These are costs for services that help you run your business legally and efficiently.

  • Accountant Fees: For preparing your Self Assessment tax return, bookkeeping, or general tax advice.
  • Legal Fees: For business-related matters, such as contract drafting, intellectual property advice, or dispute resolution. (Note: Legal fees for buying property or assets are capital expenditure).
  • Consultant Fees: For business advice, IT support, or specialist services.
  • Business Insurance: Professional indemnity insurance, public liability insurance, contents insurance for business equipment.

Example: Accountant Fees. You pay an accountant £300 to prepare and file your Self Assessment tax return. This £300 is a fully allowable expense.

6. Training and Professional Development

Costs for training are allowable if they relate to maintaining or updating skills used in your current business.

  • Courses and Workshops: To improve existing skills or learn new techniques directly relevant to your current trade.
  • Industry Conferences and Seminars: Fees and related travel costs.

Non-Allowable: New Skills for a New Business. Training to acquire a completely new skill that would enable you to start a new trade, rather than enhance your existing one, is generally not allowable. For example, if you are a graphic designer, a course on new design software is allowable. A course to become a pilot would not be, unless your graphic design business specifically involved aviation.

7. Software, Subscriptions, and IT

Modern freelancers rely heavily on technology, and many related costs are deductible.

  • Business Software: Subscriptions for accounting software (like AccountsOS), project management tools, design software, CRM systems, video conferencing platforms, and other industry-specific applications.
  • Cloud Storage and Backup Services: For storing business files securely.
  • Professional Memberships: Fees for professional bodies or trade organisations relevant to your business, if they are necessary for your work or provide professional benefits.
  • Trade Journals and Publications: Subscriptions to industry-specific magazines or online publications.

Example: AccountsOS Subscription. Your monthly subscription to AccountsOS for managing your finances is a fully allowable business expense.

8. Bank, Credit Card, and Loan Charges

Costs associated with financing and managing your business finances.

  • Business Bank Account Fees: Monthly charges or transaction fees for your business bank account.
  • Interest on Business Loans/Overdrafts: Interest paid on money borrowed specifically for business purposes.
  • Credit Card Charges: Fees and interest on credit cards used exclusively for business expenses.

Important: You cannot claim for capital repayments on loans, only the interest. Also, interest on personal loans used for business can sometimes be claimed, but it is best to keep business finances separate.

9. Clothing and Uniform

This is a tricky area, as HMRC is very strict on clothing claims.

  • Uniforms: Specific uniforms for your business, especially if branded with your logo.
  • Protective Clothing: Safety boots, hard hats, high-vis jackets, or other protective gear required for your work.

Non-Allowable: Everyday Clothing. Even if you buy expensive clothes specifically for client meetings, they are not allowable if they could also be worn outside of work. HMRC considers this 'dual purpose' and therefore non-deductible. This includes suits, dresses, shoes, etc.

10. Equipment and Capital Allowances

When you buy assets for your business that you expect to keep for more than a year, such as computers, machinery, or office furniture, these are capital expenses. You cannot deduct their full cost from your income as a revenue expense. Instead, you claim 'capital allowances'.

a. Annual Investment Allowance (AIA)

The AIA allows you to deduct 100% of the cost of most plant and machinery (including integral features of buildings) up to an annual limit. For the 2024/2025 tax year, the AIA limit is £1 million. This means that for most freelancers, you can claim the full cost of your business equipment in the year you buy it.

What qualifies for AIA?

  • Computers, laptops, tablets.
  • Printers, scanners, monitors.
  • Office furniture and fittings.
  • Tools and machinery.
  • Commercial vehicles (not cars, special rules apply).

Worked Example: Annual Investment Allowance. A freelance graphic designer buys a new high-spec computer for £2,500 and an ergonomic office chair for £500. Total capital expenditure: £3,000. Since this is below the £1 million AIA limit, the full £3,000 can be claimed as an AIA deduction in the year of purchase. This reduces their taxable profit by £3,000.

b. Writing Down Allowances (WDAs)

If you have spent more than the AIA limit, or if the asset does not qualify for AIA (e.g., cars), you can claim Writing Down Allowances. WDAs allow you to deduct a percentage of the asset's value each year.

Rates for WDAs (2024/2025):

  • Main pool: 18% per year (for most plant and machinery).
  • Special rate pool: 6% per year (for integral features of buildings, long-life assets, and thermal insulation).

Worked Example: Writing Down Allowances. A freelance photographer purchases a new camera for £3,000. They have already used their AIA for other assets.

  • Year 1: WDA at 18% = £3,000 x 18% = £540.
  • Remaining value to carry forward: £3,000 - £540 = £2,460.
  • Year 2: WDA at 18% = £2,460 x 18% = £442.80.
  • And so on, until the asset is fully written down or sold.

c. Cars

Cars have different capital allowance rules based on their CO2 emissions. They do not qualify for AIA.

  • Low emissions (up to 50g/km): 18% WDA (main pool).
  • High emissions (over 50g/km): 6% WDA (special rate pool).

If you use your car for both business and personal use, you must apportion the capital allowances based on your business usage.

11. Other Allowable Expenses

A few other categories cover various business needs.

  • Bad Debts: If a customer fails to pay an invoice and you are sure the debt will never be collected, you can claim it as an allowable expense. You must have already included the income in your accounts.
  • Subcontractor or Freelancer Costs: Payments made to other freelancers or contractors for services directly related to your business projects.
  • Business Gifts: Generally not allowable, unless they cost less than £50 per person per year, are not food, drink, tobacco, or vouchers, and carry your business branding.

Example: Unpaid Invoice. You invoiced a client £500 for services rendered, and this £500 was included in your total income. After repeated attempts, the client has gone out of business, and you are certain the £500 will not be paid. You can claim this £500 as a bad debt expense.

Common Non-Allowable Expenses

Just as important as knowing what you can claim is understanding what you cannot. Claiming non-allowable expenses can lead to penalties from HMRC.

  • Business Entertainment: Meals, drinks, or hospitality provided to clients, customers, or suppliers are generally not allowable for tax relief.
  • Personal Expenses: Any costs that are purely for your personal benefit, even if they enable you to work (e.g., your personal grocery shopping, personal clothing, childcare costs).
  • Fines and Penalties: Parking fines, speeding tickets, or penalties from HMRC are not allowable.
  • Political or Charitable Donations: These are not allowable business expenses, although some charitable donations might qualify for Gift Aid or other relief schemes.
  • Commuting Costs: As discussed, travel between your home and a regular place of work.

Simplified Expenses Scheme: A Quick Recap

HMRC introduced simplified expenses to make tax reporting easier for small businesses and self-employed individuals. You can choose to use simplified expenses for:

  • Cars, Vans, and Motorcycles: Using flat rates per mile instead of actual running costs.
  • Working from Home: Using flat rates based on hours worked from home instead of calculating a proportion of household bills.
  • Living on Your Business Premises: If you live where you work (e.g., a shop with a flat above), you can claim a flat rate deduction for personal use of the premises.

You do not have to use simplified expenses for all categories; you can mix and match. For example, you could use simplified expenses for your car but claim actual costs for working from home. Always choose the method that results in the highest legitimate deduction and is easiest for you to manage.

How Allowable Expenses Impact Your Tax Bill

Understanding the direct impact of allowable expenses on your tax liability can be a powerful motivator for meticulous record keeping.

The Calculation

Your Self Assessment tax bill is calculated on your taxable profit, not your total income.

Total Business Income - Allowable Business Expenses = Taxable Profit

This taxable profit is then added to any other income you have (e.g., employment income, rental income) to determine your total taxable income. Your Income Tax and National Insurance contributions (Class 2 and Class 4 NICs for self-employed) are then calculated based on this total.

Reducing Your Liability

Every £1 of allowable expense you claim reduces your taxable profit by £1. This means you pay less Income Tax and less Class 4 National Insurance. For a basic rate taxpayer (20% Income Tax, 6% Class 4 NICs), every £100 of allowable expenses saves you £26 in tax and NICs. For a higher rate taxpayer (40% Income Tax, 6% Class 4 NICs), that saving increases to £46 per £100.

Worked Example: Impact of Expenses. A freelancer has total business income of £40,000.

Scenario 1: No expenses claimed

  • Taxable Profit = £40,000.
  • Assuming Personal Allowance of £12,570: Taxable income for basic rate = £40,000 - £12,570 = £27,430.
  • Income Tax (20%): £27,430 x 20% = £5,486.
  • Class 4 NICs (6% on profits over £12,570): (£40,000 - £12,570) x 6% = £1,645.80.
  • Total Tax & NICs: £5,486 + £1,645.80 = £7,131.80.

Scenario 2: £5,000 in allowable expenses claimed

  • Taxable Profit = £40,000 - £5,000 = £35,000.
  • Assuming Personal Allowance of £12,570: Taxable income for basic rate = £35,000 - £12,570 = £22,430.
  • Income Tax (20%): £22,430 x 20% = £4,486.
  • Class 4 NICs (6% on profits over £12,570): (£35,000 - £12,570) x 6% = £1,345.80.
  • Total Tax & NICs: £4,486 + £1,345.80 = £5,831.80.

Saving: £7,131.80 - £5,831.80 = £1,300. Claiming £5,000 in expenses saved £1,300 in tax and NICs.

HMRC Compliance and Enquiries

Accuracy and compliance are paramount when it comes to Self Assessment. HMRC has the power to open an enquiry into your tax return if they suspect errors or omissions.

What Triggers an Enquiry?

While many enquiries are random, certain factors can increase the likelihood:

  • Unusually High Expenses: Compared to your industry average or previous years.
  • Large Fluctuations: Significant changes in income or expenses without clear justification.
  • Inconsistencies: Between your tax return and other information HMRC holds.
  • Late Filing or Payment: Repeated issues can flag your account.

During an Enquiry

If HMRC opens an enquiry, they will typically ask for detailed records and explanations for your income and expenses. This is where your meticulous record keeping becomes invaluable. You will need to provide receipts, invoices, bank statements, and other evidence to support your claims.

If HMRC finds that you have deliberately overstated expenses or made careless errors, they can impose penalties in addition to collecting any underpaid tax and interest. Penalties can range from 0% for innocent errors to 100% of the unpaid tax for deliberate and concealed errors.

Using Accounting Software

Using dedicated accounting software like AccountsOS can significantly reduce your risk of errors and make an enquiry much smoother. Such software helps you:

  • Categorise Expenses Correctly: Often with AI assistance, reducing manual errors.
  • Store Digital Receipts: Ensuring all evidence is linked to transactions and easily retrievable.
  • Generate Reports: Providing clear, organised financial statements that HMRC can easily review.

This proactive approach not only saves you time but also provides peace of mind that your tax affairs are in order.

UK Income Tax Rates 2024/25 (for context)

Your allowable expenses reduce your taxable profit, which then determines which income tax bands your earnings fall into. The rates below apply to earned income after your Personal Allowance.

Profit band Rate Name
£0 - £12,570 0% Personal Allowance
£12,571 - £50,270 20% Basic rate
£50,271 - £125,140 40% Higher rate
£125,141+ 45% Additional rate

Personal Allowance: For the 2024/25 tax year, most individuals have a Personal Allowance of £12,570, meaning you do not pay Income Tax on the first £12,570 of your earnings. This allowance is reduced if your income exceeds £100,000.

Important Self Assessment Deadlines

Online Filing Deadline

31 January following the end of the tax year (e.g., 31 January 2026 for the 2024/25 tax year).

Payment Deadline

31 January for any tax owed for the previous tax year, plus your first 'payment on account' for the current tax year.

Example: For the tax year ending 5 April 2025:

  • Online Filing Due: 31 January 2026
  • Payment Due: 31 January 2026 (for tax owed + 1st payment on account)
  • 2nd Payment on Account Due: 31 July 2026

Self Assessment Penalties

HMRC imposes penalties for late filing of your Self Assessment tax return and late payment of tax.

Scenario Penalty
1 day late £100
3 months late Additional £10 per day (max 90 days = £900)
6 months late Additional 5% of tax due (min £300)
12 months late Additional 5% of tax due (min £300)

Interest: In addition to penalties, HMRC charges interest on any tax paid late. This interest is currently set at the Bank of England base rate plus 2.5%.

Frequently asked questions

What is the 'wholly and exclusively' rule?

This is HMRC's core principle for allowable expenses. An expense must be incurred 'wholly and exclusively' for the purpose of your trade to be deductible for tax. If it has a dual purpose, personal and business, it's generally not allowable unless the business portion can be clearly separated.

Can I claim for pre-trading expenses?

Yes, you can claim for expenses incurred up to seven years before you started trading, provided they would have been allowable if incurred after the business began. These are treated as if they were incurred on the first day of trading.

Are business entertainment expenses allowable?

No, business entertainment expenses, such as taking clients out for meals or providing hospitality, are generally not allowable for tax relief. This applies even if they are genuinely for business purposes.

What records do I need to keep for expenses?

You must keep accurate records, including receipts, invoices, bank statements, and mileage logs. These records are crucial to prove your claims if HMRC conducts an enquiry into your tax return.

Can I claim for clothing?

You can only claim for clothing that is a uniform or protective clothing required for your job, such as a branded t-shirt or safety boots. Everyday clothing, even if worn for work, is not allowable as it has a dual purpose.

How do capital allowances work for freelancers?

Capital allowances allow you to deduct the cost of certain business assets, like computers or machinery, over time. The Annual Investment Allowance AIA allows you to deduct the full cost of most qualifying assets up to £1 million in the year of purchase.

What is the difference between simplified expenses and actual costs?

Simplified expenses use flat rates set by HMRC for certain costs, like vehicle mileage or working from home, making calculations easier. Actual costs require you to track and claim the precise business proportion of your expenses, which can sometimes lead to higher deductions if your costs are high.

What if my expense has a personal and business element?

If an expense has a clear identifiable business portion, you can claim that portion. For example, if you use your personal mobile phone 70% for business, you can claim 70% of the bill. If it cannot be clearly separated, such as daily commuting, it is generally not allowable.
