Making Tax Digital: Quarterly Reporting & Digital Records

Introduction to Making Tax Digital for Accountants

Making Tax Digital, MTD, represents a fundamental shift in how businesses and individuals interact with HMRC. It is a government initiative designed to modernise the UK tax system, making it more efficient, effective, and easier for taxpayers to get their tax right. For accountants, MTD is not merely a procedural change, it is a paradigm shift that redefines client relationships, internal workflows, and the very nature of tax compliance services. The core principles of MTD involve maintaining digital records and submitting tax updates directly to HMRC using MTD-compatible software.

While MTD for VAT has been mandatory for most VAT-registered businesses since 2019, the rollout of MTD for Income Tax Self Assessment, MTD for ITSA, marks a significant expansion, impacting millions of sole traders and landlords. This guide is specifically crafted to provide UK accountants with a comprehensive understanding of the current MTD landscape, with a particular focus on the quarterly reporting requirements and the stringent digital record-keeping obligations that are now mandatory. Navigating these changes effectively is crucial not only for client compliance but also for optimising practice efficiency and identifying new service opportunities.

This document will serve as an authoritative reference, detailing the specific rules, deadlines, and practical implications of MTD, ensuring that accountants are fully equipped to advise their clients and streamline their MTD compliance processes.

What is Making Tax Digital (MTD)?

Making Tax Digital is HMRC's initiative to transform the UK tax system into one of the most digitally advanced in the world. The overarching goal is to make tax administration more effective, more efficient, and simpler for taxpayers to manage. It aims to reduce common errors that arise from manual data entry and paper-based record keeping, ultimately leading to a more accurate and transparent tax system.

Core Principles of MTD

• Digital Record Keeping: Businesses and individuals subject to MTD must maintain their financial records digitally, using software or spreadsheets that meet HMRC's specifications. This replaces traditional paper ledgers and manual record-keeping systems.
• Compatible Software: Tax returns and updates must be submitted directly to HMRC using MTD-compatible software. This software must be capable of interacting with HMRC's systems via an Application Programming Interface, API, ensuring secure and accurate data transfer.
• Regular Updates: Instead of a single annual tax return, MTD requires businesses to submit regular, usually quarterly, summaries of their income and expenditure to HMRC. These updates provide HMRC with a more frequent, near real-time view of a business's financial activity.

Phases of MTD Implementation

MTD has been rolled out in phases, beginning with VAT and expanding to Income Tax Self Assessment, ITSA.

• MTD for VAT: Mandatory for VAT-registered businesses with a taxable turnover above the VAT threshold, currently £85,000, since April 2019. From April 2022, it became mandatory for all VAT-registered businesses, regardless of turnover.
• MTD for ITSA: This is the next significant phase. Initially planned for April 2024, it has been deferred and revised. As of May 2026, MTD for ITSA will apply to self-employed individuals and landlords with gross income exceeding £50,000. From April 2027, it will extend to those with gross income over £30,000.
• MTD for Corporation Tax: This phase is still in development, with a pilot expected to commence at an unspecified future date. Further details will be released by HMRC in due course.

For accountants, understanding each phase and its specific requirements is crucial for effective client management and ensuring continuous compliance across their client base. The focus of this guide is predominantly on MTD for ITSA due to its imminent and widespread impact.

Who is Affected by MTD for ITSA?

The rollout of MTD for Income Tax Self Assessment will significantly broaden the scope of MTD, impacting a vast number of self-employed individuals and landlords across the UK. Accountants must be fully aware of the qualifying criteria and implementation timelines to proactively prepare their clients.

Mandatory Compliance Thresholds and Dates

• From April 2026: MTD for ITSA becomes mandatory for self-employed individuals and landlords with gross income exceeding £50,000 per annum. This threshold applies to combined income from all self-employment businesses and property income.
• From April 2027: MTD for ITSA will extend to self-employed individuals and landlords with gross income exceeding £30,000 per annum.

It is imperative to note that the gross income threshold refers to total business and/or property income before any expenses or allowances are deducted. Accountants should begin identifying clients who meet or are likely to meet these thresholds well in advance of the mandatory start dates.

Exemptions from MTD for ITSA

While MTD for ITSA is broad in its application, certain individuals and entities may be exempt from its requirements. These exemptions are typically based on specific circumstances that make digital reporting impractical or unduly burdensome.

• Those with gross income below the threshold: Individuals whose gross income from self-employment and/or property falls below the specified thresholds (£50,000 from April 2026, £30,000 from April 2027) are not currently mandated to join MTD for ITSA. They can, however, choose to join voluntarily.
• Digital exclusion: Individuals who are genuinely unable to use digital tools due to age, disability, remote location without internet access, or other legitimate reasons may apply for an exemption. This is assessed on a case-by-case basis by HMRC.
• Religious objections: Those whose religious beliefs are incompatible with the use of electronic communications may also apply for an exemption.
• Insolvency: Individuals who are subject to insolvency procedures, such as bankruptcy, may be exempt for the duration of these proceedings.
• Trusts, Estates, and Corporate Landlords: Currently, trusts, estates, and corporate landlords are not included in the MTD for ITSA mandate. However, this may change in future phases.

Advising on Exemptions: Accountants should carefully assess each client's eligibility for exemption and assist them in making any necessary applications to HMRC. It is important to document the reasons for exemption and any communications with HMRC thoroughly. Voluntary compliance remains an option for those below the threshold who wish to embrace digital record-keeping benefits.

MTD Quarterly Reporting Requirements

The cornerstone of MTD for ITSA is the requirement for quarterly submissions of income and expenditure data. This replaces the previous system of a single annual tax return and demands a more proactive and continuous approach to record keeping and reporting.

The Quarterly Reporting Cycle

For most businesses and landlords, the tax year runs from 6 April to 5 April. Under MTD for ITSA, this is divided into four reporting periods, with a submission deadline one month and a week after the end of each quarter.

Quarterly reporting period	Submission due
6 April - 5 July	5 August
6 July - 5 October	5 November
6 October - 5 January	5 February
6 January - 5 April	5 May

These quarterly updates are essentially summaries of income and expenses for the period. They are not final tax calculations, but rather provide HMRC with an ongoing picture of a business's financial performance.

What to Include in Quarterly Updates

Each quarterly update must include a summary of all business income and expenses for that specific period. HMRC has provided a list of prescribed categories for both income and expenditure that must be used.

Income Categories

• Sales/Turnover
• Other business income
• Property income (for landlords)
• Any other relevant income streams

Expense Categories

• Motor expenses
• Rent, rates, insurance
• Repairs and maintenance
• Admin expenses (e.g., stationery, phone)
• Advertising and marketing
• Travel and subsistence
• Accountancy, legal, and other professional fees
• Salaries and wages (if applicable, for employees)
• Subcontractor costs
• Interest and bank charges
• Training costs
• Capital allowances (reported separately or at EOPS)
• Other business expenses

It is crucial that clients are accurately categorising their income and expenses throughout the year using MTD-compatible software. This ongoing categorisation will simplify the quarterly submission process. Accountants play a vital role in educating clients on these categories and ensuring the correct allocation of transactions.

End of Period Statement (EOPS)

In addition to the quarterly updates, an End of Period Statement, EOPS, must be submitted for each income source. The EOPS allows for adjustments to be made to the figures reported in the quarterly updates, ensuring that the final taxable profit or loss is accurately calculated.

• Purpose: The EOPS is where accounting adjustments are made, such as accruals, prepayments, depreciation, stock valuations, and private use adjustments. It also includes capital allowance claims and any other tax adjustments.
• Deadline: The EOPS must be submitted by 31 January following the end of the tax year, or earlier if the business's accounting period ends before the tax year end and the business chooses to align its EOPS with its accounting period.
• Per Income Source: If a client has multiple self-employment businesses or receives income from multiple properties, a separate EOPS is required for each income source.

The Final Declaration

The Final Declaration is the equivalent of the current Self Assessment tax return. It consolidates all income sources, including those not covered by MTD for ITSA, such as employment income, dividends, and interest.

• Purpose: The Final Declaration brings together all the EOPS figures, along with any other income and deductions, to calculate the individual's total tax liability for the year. This is where personal allowances, tax reliefs, and other adjustments are applied.
• Deadline: The Final Declaration must be submitted by 31 January following the end of the tax year.
• Payment: The tax calculated in the Final Declaration is due for payment by 31 January, with the first payment on account for the following tax year also due on this date.

Example Workflow: For a sole trader with a tax year ending 5 April 2027:

• Quarterly updates: Four submissions by 5 August 2026, 5 November 2026, 5 February 2027, and 5 May 2027.
• End of Period Statement (EOPS): Submitted by 31 January 2028.
• Final Declaration: Submitted by 31 January 2028.
• Tax Payment: Due by 31 January 2028.

Digital Record Keeping Obligations

A cornerstone of Making Tax Digital is the requirement for all relevant business records to be kept digitally. This is not merely about using software for submissions, it extends to the very source of the data and how it is maintained throughout the accounting period. Accountants must ensure their clients understand and adhere to these stringent requirements to avoid non-compliance penalties.

What Constitutes Digital Records?

HMRC defines digital records as those that are stored electronically within MTD-compatible software or a suitable spreadsheet. Physical documents, such as paper invoices or receipts, must be converted into a digital format, for example, by scanning or taking a photograph, and stored securely.

The following data points, at a minimum, must be recorded and preserved digitally for each transaction:

• Business name and address
• VAT registration number (if applicable)
• Business income (categorised)
• Business expenses (categorised)
• Date of transaction
• Amount of transaction
• Type of transaction (e.g., sale, purchase)
• For MTD for ITSA, specific income and expense categories as per HMRC's guidance

These records must be retained for at least 6 years from the end of the last company financial year they relate to, or longer if a tax enquiry is ongoing.

The Principle of Digital Links

A critical aspect of digital record keeping under MTD is the concept of "digital links." This requires that once data has been entered into software, any transfer or modification of that data must be done using a digital link. Manual input, such as copying and pasting figures from one spreadsheet to another, is generally not permitted if it breaks the digital audit trail.

• End-to-end digital journey: The aim is for data to flow digitally from the initial transaction recording through to the final submission to HMRC.
• Examples of digital links:
  • Automated data transfer between software programs.
  • Emailing a spreadsheet containing digital records to an accountant, who then imports it into their MTD software.
  • Using formulas in a spreadsheet to link cells or worksheets.
• Exceptions: There is a 'soft landing' period for digital links for MTD for ITSA, allowing some manual intervention for a transitional period. However, the long-term expectation is for full digital linking. Accountants should advise clients to adopt full digital linking as soon as practicable.

Transitioning from Manual to Digital Systems

For many clients accustomed to paper-based records or basic spreadsheets, the transition to fully digital record keeping can be challenging. Accountants are pivotal in guiding this transition.

• Client Assessment: Evaluate existing record-keeping practices and identify gaps in MTD compliance.
• Software Selection: Assist clients in choosing MTD-compatible software that meets their business needs and budget. AccountsOS offers a robust solution for this.
• Training and Support: Provide comprehensive training to clients on how to use new software, categorise transactions, and maintain digital records. Ongoing support will be essential.
• Data Migration: Help clients transfer historical data into new digital systems where necessary, ensuring data integrity.
• Process Documentation: Document new digital record-keeping processes to ensure consistency and compliance.

Importance of Accurate Data Entry: The accuracy of digital records is paramount. Errors at the point of entry will propagate through the MTD system, potentially leading to incorrect quarterly updates, EOPS, and Final Declarations. Accountants should emphasise the importance of regular reconciliation and review of digital records.

MTD Compatible Software

At the heart of the MTD system is the requirement to use MTD-compatible software for maintaining digital records and submitting updates to HMRC. This software acts as the crucial link between a business's financial data and HMRC's digital services. For accountants, advising clients on the right software and ensuring its correct implementation is a primary responsibility.

What Defines MTD-Compatible Software?

HMRC has set out specific criteria that software must meet to be considered MTD-compatible. These criteria ensure that the software can accurately record transactions, generate the required summaries, and communicate securely with HMRC's systems.

• Digital Record Keeping: The software must be able to digitally record all required income and expense data, as outlined in the digital record keeping section.
• Submission via API: It must be able to connect directly to HMRC's API to send quarterly updates, EOPS, and the Final Declaration without manual data re-entry.
• VAT Functionality (for MTD for VAT): For VAT-registered businesses, the software must be able to calculate the VAT due, account for adjustments, and submit the VAT return digitally.
• ITSA Functionality (for MTD for ITSA): For self-employed individuals and landlords, the software must be able to categorise income and expenses according to HMRC's prescribed categories, generate quarterly summaries, and facilitate EOPS and Final Declaration submissions.
• Data Retention: The software should allow for the digital preservation of records for the statutory period.

Types of MTD Software Solutions

There are broadly two types of software solutions that can be used for MTD compliance:

• End-to-End Accounting Software: These are comprehensive accounting packages, such as AccountsOS, Xero, QuickBooks, or FreeAgent, that manage all aspects of a business's finances from invoicing and expense tracking to bank reconciliation and MTD submissions. They are designed to provide a seamless digital journey for financial data.
• Bridging Software: For businesses that prefer to continue using spreadsheets for their primary record keeping, bridging software acts as a digital link. It takes data from a spreadsheet, maps it to HMRC's requirements, and then submits it via the API. While permissible, this approach maintains some manual intervention and carries a higher risk of error compared to end-to-end solutions.

The Role of AccountsOS in MTD Compliance

AccountsOS is designed to be an MTD VAT compliant accounting software solution. VAT MTD is live today, and AccountsOS is on HMRC's list of MTD VAT software. MTD for Income Tax (ITSA) quarterly submission support is in development ahead of April 2026.

• Automated Digital Record Keeping: AccountsOS facilitates automatic bank feeds and intelligent categorisation of transactions, ensuring that records are kept digitally from the outset.
• Real-Time Quarterly Reporting: The platform continuously updates income and expenditure figures, making quarterly submissions straightforward. Accountants can review and submit these reports with ease.
• EOPS and Final Declaration Support: AccountsOS provides the necessary tools to prepare and submit the End of Period Statements and the Final Declaration, incorporating all required adjustments and allowances.
• Client Collaboration: AccountsOS offers features for seamless collaboration between accountants and their clients, allowing for real-time data access, query resolution, and efficient workflow management.
• Compliance Assurance: By using AccountsOS, accountants can be confident that their clients' MTD submissions are accurate, timely, and fully compliant with HMRC's regulations.

Choosing the Right Software: When advising clients, accountants should consider factors such as the client's digital literacy, business complexity, specific industry needs, and budget. While bridging software can offer a temporary solution for spreadsheet users, migrating to an end-to-end platform like AccountsOS provides long-term benefits in terms of efficiency, accuracy, and compliance.

Penalties for Non-Compliance with MTD for ITSA

HMRC has introduced a new penalty regime for MTD for ITSA, designed to encourage compliance with the new quarterly reporting obligations. This system is points-based, similar to driving licence penalty points, and applies to both late submissions and late payments. Accountants must thoroughly understand this system to advise clients on avoiding penalties.

The Points-Based Penalty System for Late Submissions

This new system applies to all MTD for ITSA submissions: quarterly updates, End of Period Statements, and the Final Declaration.

Offence	Points or penalty
Late submission of quarterly update	1 point per late submission
Reaching 4 points (annual tax year)	£200 fine
Each subsequent point after 4	Additional £200 fine
Late submission of End of Period Statement (EOPS)	Separate points and fines
Late submission of Final Declaration	Separate points and fines

Each time a submission deadline is missed, the individual receives a point. Once a certain threshold of points is reached within a 12-month period, a financial penalty is issued. The threshold for points varies depending on how frequently the individual is required to submit returns:

• Quarterly filers: A penalty of £200 is issued once 4 points are accumulated within a 12-month period.
• Annual filers (for EOPS/Final Declaration): A penalty of £200 is issued once 2 points are accumulated within a 12-month period.

After a penalty is issued, additional points will result in further £200 penalties. Points expire after 12 months of being issued, provided all submissions have been made.

Late Payment Penalties and Interest

Separate penalties apply for late payment of tax liabilities. These are broadly in line with existing late payment rules for Self Assessment.

• First late payment penalty: 5% of the unpaid tax if it is not paid by 30 days after the due date.
• Second late payment penalty: An additional 5% of the unpaid tax if it is not paid by 6 months after the due date.
• Third late payment penalty: A further 5% of the unpaid tax if it is not paid by 12 months after the due date.
• Interest: HMRC also charges interest on any unpaid tax from the day the payment was due until the date it is paid in full. The interest rate is typically the Bank of England base rate plus 2.5%.

Failure to Keep Digital Records Penalties

Beyond submission penalties, HMRC can also levy penalties for failing to meet the digital record-keeping requirements. If a business does not maintain digital records or fails to use digital links where required, HMRC can impose a penalty of between £5 and £15 for every day the non-compliance continues, up to a maximum of £400. This highlights the critical importance of ensuring clients adopt and consistently apply robust digital record-keeping practices.

Accountant's Responsibility: Accountants have a crucial role in educating their clients about these penalties and implementing systems that minimise the risk of non-compliance. Regular communication, clear guidance on deadlines, and proper software setup are essential. AccountsOS provides automated reminders and a clear overview of submission statuses to help manage these risks.

The Role of the Accountant in the MTD Era

Making Tax Digital is transforming the relationship between accountants and their clients, shifting from retrospective annual compliance to proactive, real-time advisory services. Accountants are no longer just preparers of tax returns, they are essential guides, educators, and technology enablers in the digital tax landscape.

Key Responsibilities and Opportunities

• Client Education and Onboarding: Many clients will require significant guidance to understand MTD's implications. Accountants must explain the new obligations, the benefits of digital working, and the consequences of non-compliance. This involves helping clients select and implement MTD-compatible software, such as AccountsOS, and providing initial training on digital record keeping and transaction categorisation.
• System Implementation and Migration: Assisting clients in moving from manual or non-compliant systems to MTD-compatible software is a critical service. This includes data migration, setting up bank feeds, customising charts of accounts to align with HMRC's categories, and establishing efficient digital workflows. Accountants can become trusted advisors in technology adoption.
• Quarterly Review and Submission: Accountants will typically take on the responsibility of reviewing clients' quarterly digital records, making any necessary adjustments, and submitting the quarterly updates to HMRC. This requires a more frequent engagement with client data and an ability to spot and rectify errors proactively.
• End of Period Statement (EOPS) and Final Declaration Preparation: The EOPS and Final Declaration require professional judgment for adjustments, capital allowances, and other tax-specific calculations. Accountants' expertise will be invaluable in ensuring these final submissions are accurate and optimised for tax efficiency.
• Advisory Services: With more up-to-date financial data available through digital systems, accountants can offer more timely and relevant business advice. This could include cash flow forecasting, performance analysis, budget setting, and strategic planning, moving beyond historical reporting to proactive guidance.
• Compliance Monitoring and Risk Management: Accountants will be instrumental in monitoring client compliance with MTD deadlines and ensuring that digital records are maintained correctly. This helps clients avoid penalties and minimises their exposure to HMRC inquiries.
• Upskilling and Training: Accountancy practices themselves must invest in training their staff on MTD regulations, compatible software, and digital advisory skills. Embracing cloud-based solutions and automation tools is essential for practice efficiency.

Leveraging AccountsOS for Practice Efficiency

AccountsOS provides a comprehensive platform that empowers accountants to navigate the MTD landscape effectively and efficiently.

• Centralised Client Management: Manage multiple clients from a single dashboard, with clear visibility of their MTD status, deadlines, and financial data.
• Automated Data Processing: Reduce manual data entry with bank feeds, receipt scanning, and AI-powered categorisation, freeing up time for advisory work.
• Seamless MTD Submissions: Prepare and submit quarterly updates, EOPS, and Final Declarations directly to HMRC through a secure, MTD-compliant interface.
• Real-Time Financial Insights: Access up-to-date client financial information to provide timely advice and identify potential issues before they become problems.
• Collaborative Tools: Facilitate easy communication and document sharing with clients, streamlining the information gathering process.

Embracing the Advisory Role: MTD presents a significant opportunity for accountants to evolve their service offerings. By embracing digital tools and proactive engagement, practices can move away from being reactive compliance providers to becoming indispensable strategic partners for their clients, adding greater value and securing long-term client relationships.

Worked Examples for MTD for ITSA

Understanding the theoretical aspects of MTD for ITSA is essential, but practical application often clarifies the process. Below are worked examples illustrating the quarterly reporting, End of Period Statement, and Final Declaration for a hypothetical sole trader.

Example 1: Sole Trader Quarterly Update

Consider Sarah, a self-employed graphic designer, whose tax year runs from 6 April to 5 April. Her first MTD for ITSA quarterly reporting period is 6 April 2026 to 5 July 2026.

Sarah's Financial Activity (6 April - 5 July 2026)

Category	Amount (£)
Income:
Sales / Turnover	12,500
Expenses:
Office Costs (Rent, Utilities)	900
Software Subscriptions	150
Professional Fees (Accounting)	250
Travel Expenses	120
Training Costs	300
Total Income	12,500
Total Expenses	1,720
Net Profit for Quarter	10,780

Sarah's accountant, using AccountsOS, reviews these digitally recorded transactions. No adjustments are needed for this quarter's summary. The report is submitted to HMRC by 5 August 2026.

Example 2: End of Period Statement (EOPS) for Sarah

After four quarterly updates, Sarah's total reported income and expenses for the tax year ending 5 April 2027 are:

Sarah's Annual Totals from Quarterly Updates

Category	Amount (£)
Total Sales / Turnover	50,000
Total Business Expenses	8,000
Net Profit before Adjustments	42,000

For the EOPS, Sarah's accountant identifies the following adjustments:

• Capital Allowances: £1,500 for a new computer purchased.
• Private Use Adjustment: £200 of motor expenses were for personal use and need to be added back.
• Accrued Expenses: £100 for an invoice received after year-end but relating to the tax year.

EOPS Calculation

Item	Amount (£)
Net Profit from Quarterly Updates	42,000
Less: Capital Allowances	(1,500)
Add: Private Use Adjustment	200
Less: Accrued Expenses	(100)
Adjusted Taxable Profit (for EOPS)	40,600

The EOPS is submitted to HMRC by 31 January 2028. This figure of £40,600 is then fed into the Final Declaration.

Example 3: Final Declaration for Sarah

In addition to her graphic design business, Sarah also has employment income from a part-time job and receives some bank interest.

Sarah's Final Declaration Calculation

Item	Amount (£)
Adjusted Taxable Profit (from EOPS)	40,600
Employment Income (Gross)	15,000
Bank Interest	150
Total Gross Income	55,750
Less: Personal Allowance (e.g., £12,570)	(12,570)
Total Taxable Income	43,180

The Final Declaration calculates the tax due based on Sarah's total taxable income, applying the relevant income tax rates. It also includes any tax already paid through PAYE on her employment income and tax credits.

The Final Declaration is submitted, and the tax due is paid by 31 January 2028. This example simplifies tax calculations for illustrative purposes, but demonstrates the flow of information from quarterly updates to the final tax liability.

Frequently asked questions

What is Making Tax Digital (MTD)?

Making Tax Digital is HMRC's initiative to digitalise the UK tax system. It requires businesses and individuals to keep digital records and submit tax updates using MTD-compatible software, aiming to reduce errors and modernise tax administration.

Who needs to comply with MTD for ITSA?

From April 2026, self-employed individuals and landlords with gross income over £50,000 must comply. From April 2027, this extends to those with gross income over £30,000. Certain exemptions apply for digital exclusion or religious objections.

What are MTD quarterly updates?

Quarterly updates are summaries of a business's income and expenses submitted to HMRC every three months using MTD-compatible software. These provide HMRC with a more frequent overview of financial activity, replacing a single annual report.

What records must be kept digitally under MTD?

All relevant business records, including income, expenses, and transaction dates and amounts, must be kept digitally. This means using software or digitally linked spreadsheets, and converting any paper documents to digital format.

Can clients still use spreadsheets for MTD?

Yes, but only if they are digitally linked to MTD-compatible bridging software. Manual transfer of data from a spreadsheet to another system is generally not permitted, as it breaks the digital audit trail.

What is an End of Period Statement (EOPS)?

The EOPS is an annual statement submitted for each income source, allowing for accounting adjustments like accruals, depreciation, and capital allowances. It ensures the final taxable profit or loss is accurately calculated before the Final Declaration.

What happens if a client misses an MTD deadline?

HMRC operates a points-based penalty system for late submissions under MTD for ITSA. Each missed deadline incurs a point, and accumulating a certain number of points within a 12-month period results in a financial penalty, typically £200.

How can AccountsOS help accountants with MTD compliance?

AccountsOS offers MTD-compatible software for digital record keeping, automated quarterly reporting, and seamless submission of EOPS and Final Declarations. It provides tools for client collaboration, compliance monitoring, and real-time financial insights to streamline MTD processes for accounting practices.
