MTD for Income Tax: Complete UK Guide to Rules, Deadlines and Reporting

Making Tax Digital for Income Tax is now in force. If you are self-employed, receive rental income or have both sources of income, the way you report your finances to HMRC may already have changed.

Introduced on 6 April 2026, Making Tax Digital for Income Tax is one of the most significant changes to Self Assessment in recent years. It replaces the traditional approach of reporting business and property income only through an annual tax return with a system of digital record-keeping and regular quarterly updates.

The rules are being introduced gradually, bringing more sole traders and landlords into the system in April 2027 and April 2028.

This comprehensive guide from Naail & Co Chartered Certified Accountants & Tax Advisors explains who must comply, how qualifying income is calculated, what records you need, when submissions are due and how to prepare for HMRC’s requirements.

What Is MTD for Income Tax?

Making Tax Digital for Income Tax (MTD for Income Tax) is HMRC’s digital system for reporting self-employment and property income. Individuals within the regime must use compatible software to maintain digital records, submit four quarterly updates and complete an annual tax return.

It applies to eligible sole traders and landlords whose combined qualifying income exceeds the relevant threshold. The purpose is to make tax reporting more regular, improve record accuracy and give taxpayers a clearer view of their financial position throughout the year.

Are You Required to Comply With MTD for Income Tax?

MTD changes how and when financial information is reported to HMRC. It does not introduce a new Income Tax or require Income Tax to be paid every quarter.

Not everyone who submits a Self Assessment tax return is required to use MTD for Income Tax. Eligibility depends on income sources, qualifying income, the relevant tax year and any applicable exemptions.

HMRC is introducing Making Tax Digital for Income Tax in three main stages.

Mandatory start dateQualifying incomeTax year used to assess eligibility
6 April 2026More than £50,0002024/25
6 April 2027More than £30,0002025/26
6 April 2028More than £20,0002026/27

When Does MTD for Income Tax Become Mandatory?

HMRC is introducing Making Tax Digital for Income Tax in three main stages.

The thresholds refer to qualifying income, not taxable profit.
For example, an individual with £55,000 in gross self-employment income and £30,000 in allowable business expenses may have taxable trading profits of £25,000. Nevertheless, their qualifying income for MTD purposes would generally be £55,000.

Equally, someone receiving £22,000 from self-employment and £17,000 in gross rental income has combined qualifying income of £39,000. Subject to the applicable eligibility conditions and exemptions, this would bring them into MTD from April 2027 if those amounts were reported for 2025/26.

The thresholds are strictly more than £50,000, £30,000 or £20,000. Having income exactly equal to the relevant threshold does not, by itself, meet that threshold.

HMRC generally assesses eligibility using the Self Assessment tax return for the relevant earlier tax year. However, amended returns, shorter accounting periods, ceased income sources and other special circumstances may affect the assessment.

For current eligibility criteria, see HMRC’s official MTD for Income Tax guidance.

How Is Qualifying Income Calculated for MTD?

One of the most important aspects of Making Tax Digital is understanding which income HMRC includes when deciding whether you must comply.

Qualifying income generally consists of your gross income from:

  • Self-employment, including sole trader businesses.
  • UK property letting.
  • Overseas property letting, where the relevant tax residence rules require that income to be included.
  • Multiple self-employment or property income sources, considered together.

It is calculated before deducting business or property expenses.

Even though neither income source individually exceeds £50,000, the combined qualifying income is £53,000.
Assuming this was the qualifying income reported for 2024/25 and no exemption applies, MTD for Income Tax became mandatory from 6 April 2026.

Income source Gross annual income
Consultancy business £28,000
Residential rental property £25,000
Total qualifying income £53,000

What Income Does Not Count Towards the MTD Threshold?

The following generally do not form part of qualifying income:

  • Employment income taxed through PAYE.
  • Dividends, including dividends received from your own limited company.
  • State and private pension income.
  • Savings interest.
  • An individual’s share of partnership profits.

These amounts may still need to be reported on the annual tax return where applicable.

For example, a company director receiving £80,000 in salary and dividends, alongside £15,000 in gross rental income, would not normally enter MTD solely because their total personal income exceeds £50,000.
Their qualifying income for this purpose would generally be £15,000, not £95,000.
Certain categories of income, accounting periods, tax residence arrangements and relief claims require more detailed consideration.

Who Must Use MTD for Income Tax?

Sole Traders and Self-Employed Individuals

Sole traders, freelancers, consultants, contractors and other self-employed individuals may be required to use MTD when their qualifying income exceeds the relevant threshold.

This includes individuals carrying on more than one self-employed business.

Each relevant trade generally has its own digital record-keeping and quarterly reporting requirements.

Landlords and Property Investors

Individual landlords receiving qualifying property income may also fall within MTD.

This can include people with:

  • One or several residential rental properties.
  • Commercial property income.
  • Jointly owned rental properties.
  • UK and overseas rental income.
  • Property income alongside employment or self-employment.


The number of properties does not determine MTD eligibility. What matters is qualifying income and the applicable rules.

For individual landlords, UK rental properties are generally treated as one UK property business for quarterly reporting purposes, rather than requiring a separate quarterly update for each property.
Foreign property income has separate record-keeping considerations.

Individuals With More Than One Income Source

MTD can become more complicated when someone has several businesses, rental properties or other taxable income.

For example, a taxpayer might operate a consultancy business, own jointly let property and receive investment dividends.

Some income sources count towards MTD eligibility; others affect only the annual tax calculation.
Understanding that distinction is essential.

Partnerships and Limited Companies

Ordinary partnership income is not currently subject to MTD for Income Tax quarterly reporting under the individual sole trader and landlord rollout. HMRC has not yet announced the mandatory implementation date for partnerships.

Limited companies are not brought into MTD for Income Tax because of their Corporation Tax profits.
However, company directors and partners may still have personal qualifying income from separate self-employment or property activities.

Non-Resident Landlords and Overseas Income

Residence status can affect which income is included when assessing MTD eligibility.
For UK tax residents, both UK and relevant overseas property income may count.

For non-UK residents, the calculation generally focuses on UK property income and self-employment income declared on the UK Self Assessment return.

Certain taxpayers with overseas income or residence-related supplementary pages may qualify for specific transitional exemptions. These should be checked individually rather than assuming all non-residents are exempt.

What Are the Main Requirements of Making Tax Digital for Income Tax?

There are three principal obligations: keeping digital records, sending quarterly updates and completing an annual tax return using compatible software.

Keeping Digital Records

Taxpayers within MTD must create and maintain digital records of relevant income and expenses.

Digital records generally include:

  • The date of each transaction.
  • The amount received or paid.
  • The appropriate income or expense category.

For sole traders, this may cover sales income, purchases, professional expenses, travel, subcontractor costs and other business transactions.

For landlords, it may include rental receipts, repairs, agent fees, property expenses and relevant finance costs.

Taxpayers must continue to retain supporting documentation, such as invoices and bank statements, in accordance with normal tax record-keeping requirements.

Simply having a bank feed does not mean your books are accurate. Transactions must still be correctly identified, categorised and reviewed.

Submitting Quarterly Updates

MTD requires regular submissions of income and expense summaries to HMRC.

A quarterly update is not a complete tax return and does not normally involve calculating the final tax liability.

The updates are cumulative, meaning each submission covers the tax year to date rather than only the latest three months.

Completing Your Annual Tax Return

After the tax year ends, taxpayers must review their accounting information, make necessary adjustments, add other taxable income and gains, claim relevant reliefs and submit an annual tax return through compatible software.
The annual tax return remains an essential part of the MTD process.

It is important not to confuse quarterly reporting with finalising your tax affairs.

MTD Quarterly Update Deadlines Explained

For individuals using standard tax-year reporting periods, the quarterly deadlines are:
Reporting period Submission deadline
6 April – 5 July 7 August
6 April – 5 October 7 November
6 April – 5 January 7 February
6 April – 5 April 7 May
For the first mandatory cohort in 2026/27, the submission deadlines are:
  • 7 August 2026
  • 7 November 2026
  • 7 February 2027
  • 7 May 2027
The annual MTD tax return for 2026/27 is due by 31 January 2028.

Calendar Quarters vs Tax Year Quarters

Taxpayers may use calendar update periods where appropriate.
These run to:

  • 30 June.
  • 30 September.
  • 31 December.
  • 31 March.

Importantly, the filing deadlines remain 7 August, 7 November, 7 February and 7 May.

Your reporting-period selection should be checked before submitting the first quarterly update. It cannot simply be changed partway through a tax year after an update has been submitted.

Are MTD Quarterly Updates Cumulative?

Yes.
For example, your second quarterly update normally includes income and expenses from the start of the relevant tax year through to 5 October, rather than only transactions from July to October.

Similarly, the third and fourth updates include cumulative financial information.

This allows corrections to earlier digital records to be reflected in later quarterly submissions without automatically having to resubmit each previous update.

Do Quarterly Updates Trigger Tax Payments?

No.
MTD does not introduce a requirement to pay Income Tax every three months.

Taxpayers must still comply with normal Self Assessment payment obligations, including payments on account where applicable.

Quarterly updates can assist with tax forecasting, but the figures submitted do not automatically establish the final amount of Income Tax payable.

What Happens at the End of the Tax Year?

The annual return is where the overall tax position is finalised.

Before submitting it, taxpayers and their accountants may need to:

  • Reconcile digital records with accounting information.
  • Correct errors and review transaction classifications.
  • Consider allowable business and property expenses.
  • Make relevant accounting adjustments.
  • Claim capital allowances or other applicable reliefs.
  • Account for losses and relevant elections.
  • Add employment, pension, dividend and savings income where required.
  • Report relevant chargeable gains and other tax information.
  • Review the final tax calculation.

For the first mandatory MTD year, 2026/27, the annual tax return must be submitted by 31 January 2028.

Taxpayers entering MTD in April 2026 must also complete their preceding 2025/26 Self Assessment tax return by the normal deadline of 31 January 2027.

MTD changes the reporting method. It does not remove the need for proper year-end tax calculations and professional judgement.

What Software Do You Need for MTD for Income Tax?

HMRC requires MTD-compatible software to maintain digital records, submit quarterly updates and complete the annual tax return.

There are different ways to meet these requirements.

Software approachHow it worksMay suit
Cloud accounting softwareRecords transactions and supports MTD submissionsSole traders and businesses needing ongoing bookkeeping
Property accounting softwareRecords rental transactions and property expensesLandlords with relevant property income
Spreadsheet and bridging softwareConnects existing spreadsheets to compliant submission softwareTaxpayers with suitable established spreadsheets
Combination of compatible productsUses different software for record-keeping, quarterly updates or annual reportingTaxpayers with multiple income sources or more complex arrangements

Recognised software may include products from providers such as Xero, Sage, QuickBooks and FreeAgent, depending on the specific product and supported functionality.

Software suitability matters more than the software brand.

For example, a product that handles quarterly updates may not support every additional income source required for your annual tax return.

Some taxpayers can use free software, subject to the provider’s eligibility criteria and functionality limits.

Spreadsheets can also remain part of a compliant arrangement when supported by appropriate compatible software.

HMRC’s Making Tax Digital software finder can help identify products suitable for different circumstances.

MTD for Landlords: Important Property Tax Considerations

Landlords should pay particular attention to how their income is calculated and recorded.

Jointly Owned Rental Properties

Where property is jointly owned, the relevant individual’s share of rental income normally counts towards their own qualifying income.

For example, if two siblings share £60,000 of rental income equally, their respective shares would generally be £30,000 each before considering other qualifying income.

Joint ownership does not automatically mean that the property is operated through a tax partnership.

HMRC has also introduced special record-keeping and quarterly reporting easements for qualifying jointly let properties.

These can allow simplified records and, in some cases, the omission of jointly let property expenses from quarterly updates, provided the necessary information is included before the annual tax return is completed.

The appropriate treatment depends on the ownership and reporting circumstances.

Multiple UK Rental Properties

An individual who owns several UK rental properties generally operates one UK property business for Income Tax purposes.

Digital records must properly reflect the relevant income and expenses, but multiple UK properties do not automatically require separate quarterly submissions for each property.

Overseas Rental Properties

Foreign property income can create additional record-keeping requirements.

HMRC generally requires digital records for each foreign property, with the information aggregated into the relevant foreign property business quarterly update.

Tax residence status, foreign tax relief and exchange-rate considerations may also affect the annual tax return.

Property Expenses and Mortgage Interest

Digital records should distinguish allowable property expenses from expenditure that requires different tax treatment.

Residential mortgage interest and other finance costs can be subject to restrictions for individual landlords.

Correct classification is important because the quarterly reporting figures do not replace the separate tax rules governing property income.

This can include:

  • Recording business income promptly.
  • Reconciling bank accounts.
  • Distinguishing personal and business expenditure.
  • Recording payments to suppliers and subcontractors.
  • Managing receipts and invoices.
  • Reviewing expense categories.
  • Keeping separate records for different trades where required.

MTD for Sole Traders: What Changes in Practice?

For sole traders, MTD makes timely bookkeeping more important.

A business that previously prepared its accounts once a year may now need to organise transactions regularly to meet quarterly filing requirements.
This can include:

  • Recording business income promptly.
  • Reconciling bank accounts.
  • Distinguishing personal and business expenditure.
  • Recording payments to suppliers and subcontractors.
  • Managing receipts and invoices.
  • Reviewing expense categories.
  • Keeping separate records for different trades where required.

The cash basis is the default method for many unincorporated businesses, subject to applicable rules and elections. However, MTD itself does not create an entirely new system for deciding whether income and expenditure is taxable.
A taxpayer’s accounting method and the normal tax legislation remain relevant.

Where someone operates multiple trades or has both trading and property income, their software and accounting arrangements need to support the separate reporting requirements.

MTD Exemptions: Who May Not Need to Comply?

Some taxpayers are exempt from Making Tax Digital for Income Tax automatically, while others must apply to HMRC.

The exemptions are more detailed than simply being unfamiliar with computers.

Age alone does not automatically exempt someone from MTD.

Likewise, preferring paper records or finding new software inconvenient will not necessarily qualify someone for an exemption.

HMRC considers the applicable criteria and, where required, supporting information.
Taxpayers who are exempt from MTD may still need to submit Self Assessment returns in the usual way.

See HMRC’s MTD exemption guidance for current eligibility conditions.

Depending on the circumstances, exemptions may arise because of:

  • Digital exclusion resulting from disability, age or other circumstances that make it not reasonably practicable to use digital tools.
  • Religious beliefs incompatible with electronic communications.
  • Certain automatic exemptions based on the taxpayer’s status or information provided on previous tax returns.
  • Specific temporary exemptions affecting particular categories of taxpayer.
  • Income below the relevant mandatory threshold.

Age alone does not automatically exempt someone from MTD.

Does MTD for Income Tax Replace Self Assessment?

MTD changes the way affected taxpayers complete Self Assessment, but it does not eliminate the annual reporting and tax calculation process.
Under the traditional approach, a sole trader or landlord might maintain records throughout the year and submit one annual tax return.

Under MTD, eligible taxpayers maintain specified digital records, submit quarterly updates and complete their annual tax return using compatible software.

There are also important differences between MTD for Income Tax and MTD for VAT.

MTD for Income TaxMTD for VAT
Applies to eligible sole traders and landlordsApplies to VAT-registered businesses
Eligibility is based on qualifying income and other conditionsLinked to VAT registration
Reports self-employment and property income and expensesReports VAT information
Requires quarterly updates and an annual tax returnRequires VAT returns for prescribed VAT periods
Uses compatible Income Tax reporting softwareUses MTD-compatible VAT software

Being compliant with MTD for VAT does not automatically mean you are ready for MTD for Income Tax.

A VAT-registered sole trader may need to meet both sets of obligations.

Professional Insight: MTD Is More Than a Software Change

The greatest practical risk with Making Tax Digital is treating software adoption as the same thing as tax compliance.

An accounting system may be capable of submitting quarterly updates, but it cannot independently determine whether every transaction has been categorised correctly, every allowable relief has been considered or the taxpayer’s full annual income has been reported.

Several points deserve particular attention.

  • Qualifying income is not the same as taxable profit. Business owners with significant expenses may be required to use MTD even if their profits are relatively modest.
  • Property ownership needs careful treatment. Joint ownership, multiple properties and overseas income can affect the eligibility calculation and record-keeping obligations.
  • Quarterly information is not a final tax calculation. Accounting adjustments, allowances, losses and other taxable income can materially change the ultimate liability.
  • Changing software does not remove existing obligations. Digital records and previous submissions must remain accessible, including where a taxpayer changes accountants or software providers.
  • Joining MTD is not necessarily reversible simply because income falls. HMRC has specific rules governing when taxpayers can opt out after qualifying income falls below the relevant threshold.

The most effective approach is to use MTD as an opportunity to improve financial record-keeping, while retaining the professional tax review needed to ensure that the correct amount of tax is calculated and reported.

Frequently Asked Questions About MTD for Income Tax

What is MTD for Income Tax in simple terms?

MTD for Income Tax is HMRC’s digital reporting system for eligible sole traders and landlords. It requires digital income and expense records, cumulative quarterly updates and an annual tax return through compatible software. It changes the reporting process rather than creating a new tax.

When does MTD for Income Tax become mandatory?
MTD became mandatory on 6 April 2026 for eligible taxpayers with qualifying income above £50,000 based on 2024/25. The next phases begin on 6 April 2027 for income above £30,000 based on 2025/26 and 6 April 2028 for income above £20,000 based on 2026/27.
Is MTD for Income Tax based on turnover or profit?

MTD eligibility is generally based on gross qualifying income from self-employment and property, before expenses. It is not based on taxable profit. A taxpayer can therefore exceed the MTD threshold even where allowable costs significantly reduce their taxable income.

Do landlords need to use MTD for Income Tax?

Individual landlords must use MTD for Income Tax when their qualifying income exceeds the relevant threshold and they meet the applicable conditions. Their share of jointly owned rental income can count, as can relevant overseas property income. The number of properties alone does not determine eligibility.

Can I still use Excel for MTD for Income Tax?

Yes, spreadsheets can form part of a compliant MTD arrangement when connected to suitable compatible software. Excel alone will not necessarily meet all the record-keeping and submission requirements. The full software arrangement must support your relevant quarterly updates and annual tax return.

Do I have to pay Income Tax every three months under MTD?

No. MTD requires quarterly reporting, not compulsory quarterly Income Tax payments. Existing Self Assessment payment deadlines, including payments on account where applicable, remain relevant.

What happens if I make a mistake in an MTD quarterly update?

You should correct your digital records as soon as you become aware of an error. Because quarterly updates are cumulative, the corrected amounts can generally be included in a later update without separately resubmitting every earlier quarterly report. Annual tax return corrections have separate requirements.

Are pension income and dividends included in the MTD qualifying income threshold?

No. Pension income, employment earnings, dividends and savings interest generally do not count towards the qualifying income threshold. However, these income sources may still need to be included when completing the annual tax return.

Can I be exempt from MTD for Income Tax?

Yes. Certain taxpayers qualify for automatic exemptions, while others may apply because digital record-keeping and electronic communications are not reasonably practicable in their circumstances. Exemptions depend on specific HMRC rules; being older or unfamiliar with technology does not automatically qualify someone.

Do I need an accountant for MTD for Income Tax?

An accountant is not legally compulsory. However, professional assistance can be valuable where you have multiple income sources, rental properties, unfamiliar accounting software or complex year-end adjustments. An authorised accountant can help manage your MTD registration, digital records, quarterly updates and annual return.
