MTD for Income Tax: 2026 Rules

MTD for Income Tax is now changing how eligible sole traders and landlords manage Self Assessment. Instead of organising business records only when the annual return is due, affected taxpayers must maintain digital records throughout the year and send summary updates to HMRC every three months. The first mandatory phase began on 6 April 2026 for people whose qualifying income exceeded £50,000 in the 2024/25 tax year.

The reform does not introduce a new Income Tax or change the dates on which Self Assessment tax must be paid. It changes the records, software and reporting process used to provide information to HMRC. Eligible taxpayers still submit one tax return and pay the final amount due by 31 January following the end of the tax year.

Checking the rules early is important because the threshold is based on gross qualifying income, not taxable profit. A taxpayer can therefore come within MTD for Income Tax even when allowable expenses leave a much smaller profit. The following sections explain the current thresholds, deadlines, digital record requirements and practical preparation steps.

What Is MTD for Income Tax?

Making Tax Digital for Income Tax is a new way of completing Self Assessment for people with qualifying self-employment or property income. It requires the taxpayer or their agent to use commercial software that works with HMRC. That software must create or connect to digital records, send quarterly summaries and submit the annual tax return.

As explained in HMRC’s current MTD for Income Tax guidance, the annual tax return and existing payment timetable remain in place. The main change is that business and property records must be maintained digitally and reported more regularly. MTD does not require tax to be paid every quarter, and a quarterly update is not a tax return.

The system applies only after a person has registered for Self Assessment and submitted their first return. Someone starting a new business will therefore normally complete an initial Self Assessment return before HMRC assesses whether MTD applies. Our Self Assessment tax return guide explains the wider registration and annual filing process.

What Is MTD ITSA?

MTD ITSA and MTD for Income Tax refer to the same digital reporting reform. “ITSA” stands for Income Tax Self Assessment, while HMRC’s current public guidance generally uses the shorter name “Making Tax Digital for Income Tax.” Older software pages, professional articles and correspondence may still use MTD ITSA.

The reform sits within the existing Self Assessment system rather than creating a separate tax. Eligible people continue to report all taxable income and gains, claim relevant allowances and confirm that their annual information is complete. The difference is that self-employment and property transactions must be recorded digitally during the year.

Some older explanations also refer to an “end of period statement” and a “final declaration.” HMRC’s current process instead instructs taxpayers to correct their records, make necessary tax adjustments, add other income and submit their tax return through compatible software. Relying on current terminology can prevent confusion when choosing software or discussing responsibilities with an accountant.

Who Must Comply With MTD for Income Tax?

According to HMRC’s eligibility rules, a person must use MTD when all the relevant conditions apply. They must be registered for Self Assessment, receive income from self-employment or property, and have qualifying income above the applicable threshold. The requirements apply to individuals operating as sole traders and individuals receiving property income.

Qualifying income is the combined gross income from all self-employment and property sources before expenses are deducted. For example, £28,000 of gross trading income and £24,000 of gross rental income produce qualifying income of £52,000. The calculation combines the two sources even if neither exceeds the threshold separately.

HMRC’s qualifying-income guidance confirms that employment income, dividends, pensions and an individual partner’s share of partnership profit are not included. Those amounts may still need to be reported on the annual tax return, but they do not determine whether the MTD threshold is exceeded. A taxpayer should check the gross figures shown on the relevant Self Assessment return instead of using accounting profit or total taxable income.

Who is not currently required to join?

Partnerships are not currently required to use MTD for Income Tax, although HMRC intends to bring them into the system in the future and has not yet published a start date. Limited companies are also outside MTD for Income Tax because their profits are dealt with through Corporation Tax rather than individual Self Assessment. An individual partner may still need MTD for separate sole-trade or property income that exceeds the threshold.

A person may also be exempt because of their income level, role or circumstances. Qualifying income of £20,000 or less is automatically outside the mandatory system under the current rules. Other automatic and temporary exemptions cover specified cases, while digital exclusion normally requires an application to HMRC.

Digital exclusion

As set out in the official exemption guidance, HMRC may approve an exemption when it is not reasonable for someone to use compatible software. Relevant factors can include age, a health condition, disability, religious beliefs or an inability to obtain suitable internet access because of location. HMRC considers applications individually.

Previously filing on paper, being unfamiliar with accounting software, having few transactions or facing additional cost is not enough by itself. An approved exemption removes the MTD software obligations, but it does not remove the requirement to report taxable income. The taxpayer must continue submitting Self Assessment returns through the method agreed with HMRC.

MTD for Income Tax Deadlines

The rollout is based on qualifying income reported for an earlier tax year. HMRC reviews the submitted Self Assessment return and uses its gross self-employment and property figures to identify the appropriate start date. The current mandatory timetable is:

• 6 April 2026: qualifying income above £50,000 in the 2024/25 tax year.
• 6 April 2027: qualifying income above £30,000 in the 2025/26 tax year.
• 6 April 2028: qualifying income above £20,000 in the 2026/27 tax year.

The threshold is “more than” the stated amount. Qualifying income of exactly £50,000 does not meet the above-£50,000 test, although a lower threshold may bring the taxpayer into the system in a later phase. HMRC normally writes to people it identifies, but not receiving a letter does not remove the taxpayer’s responsibility to check and sign up.

Once someone is required to use MTD, a single temporary fall in income does not automatically remove them. HMRC states that a person can choose to opt out after their qualifying income has remained below the relevant threshold for three consecutive tax years. Separate rules apply if every qualifying self-employment and property source has ceased.

How MTD for Income Tax Works

The process begins with recording business or property income and expenses in compatible software. Every three months, the software adds together the relevant records for each business source and sends a summary to HMRC. These submissions are intended to show income and expense category totals rather than copies of individual receipts or invoices.

HMRC expressly describes quarterly updates as summaries rather than tax returns. The taxpayer does not normally need to make accounting or tax adjustments before sending them. After an update, the software or HMRC online account can show an estimated tax position, but the estimate may be incomplete when other income or year-end adjustments have not yet been added.

After the fourth update, the taxpayer checks the digital records, corrects errors and makes any required accounting or tax adjustments. Other taxable income and gains must then be included in the compatible software. The completed annual tax return must be submitted by 31 January following the end of the tax year.

Quarterly update periods

Standard update periods follow the tax year, while calendar update periods are available for businesses using accounts to 31 March. Both options have the same submission deadlines. Under the standard periods, the reporting cycle is:

• 6 April to 5 July: submit by 7 August.
• 6 April to 5 October: submit by 7 November.
• 6 April to 5 January: submit by 7 February.
• 6 April to 5 April: submit by 7 May following the tax year.

Each submission is cumulative from the beginning of the tax year to the end of that update period. The second update therefore includes records from 6 April to 5 October rather than only the latest three months. As per HMRC’s quarterly-update instructions, this design allows corrected records to flow into a later update without resending every earlier submission.

A separate update is required for each self-employment business and each relevant property business. Even when no income or expense arose during the latest period, an update must still be sent. Software should display the applicable periods and deadlines after it has been configured correctly.

Digital Record-Keeping Requirements

The digital records must cover self-employment and property income and expenses. For a sole trader, this can include sales, fees, stock costs, travel and office expenses. For a landlord, it can include rent, repairs, maintenance and other property costs.

HMRC’s digital record guidance requires each transaction record to include its amount, date and relevant Self Assessment category. If a person operates more than one sole-trade business, separate digital records and quarterly updates are normally required for each one. Digital records do not generally have to be created for employment income, dividends, savings or pensions, although these amounts must still be included on the annual return where taxable.

Using digital records does not remove the normal obligation to retain supporting evidence such as invoices, receipts and bank statements. The records must be accurate and retained for the applicable Self Assessment period. More detail on supporting documents and retention periods is available in our UK tax record-keeping guide.

Digital links between software

A digital link is required when more than one software product transfers MTD business records. The transfer can use linked spreadsheet cells, CSV files, imports, exports or an automated connection. Once a record has formed part of an update, manually copying and pasting it between record-keeping and submission software is not an acceptable digital transfer.

A bank feed can reduce manual work, but imported transactions still need to be checked and categorised correctly. Some transactions may be incomplete or missing from a feed, and personal transactions may require exclusion. Responsibility for accurate records remains with the taxpayer even when automation or an agent is used.

Making Tax Digital Software

HMRC does not provide the commercial accounting software needed for MTD for Income Tax. A taxpayer can use an all-in-one accounting product or combine products that work together. The selected setup must cover every task and income source relevant to the taxpayer’s circumstances.

Spreadsheets can still be used if compatible bridging software connects them to HMRC. As confirmed in the official software guidance, bridging software can use existing spreadsheet records to send quarterly updates and the annual return. The digital-link rules must still be followed when information moves between products.

Before purchasing software, check whether it supports sole-trade income, UK property income, foreign property income and any other sources that must appear on the annual return. It should also support the correct accounting period and allow adjustments and corrections. A VAT-registered business should check whether its current software supports both MTD for VAT and MTD for Income Tax.

HMRC’s MTD software finder lists products that have passed its recognition process. HMRC does not recommend one supplier over another. Free products may be available for simple affairs, but they can impose limits on transaction numbers, income types or features.

Digital Tax Returns and Quarterly Updates

Calling each quarterly update a “digital tax return” can create the wrong impression. A quarterly update contains category totals drawn from digital records and does not require the full declarations or year-end tax adjustments of an annual return. It also does not normally trigger a quarterly Income Tax payment.

The annual return remains the legally significant completion of the taxpayer’s overall Self Assessment position. HMRC may pre-populate information including PAYE income, pensions, taxable state benefits, student loan details and some capital gains information. The taxpayer must check that information and add missing items such as savings interest, dividends, partnership profit and other taxable gains.

According to HMRC’s submission process, the taxpayer must review the calculation and declare that the information is correct and complete to the best of their knowledge. The return is then submitted through MTD-compatible software. The deadline remains 31 January following the relevant tax year.

MTD does not change the way Self Assessment tax is paid or the standard payment dates. Payments on account may still be due on 31 January and 31 July, with any balancing payment due on 31 January. Quarterly estimates should therefore be treated as planning figures rather than immediate payment demands.

MTD for Sole Traders and Landlords

A sole trader should not use net profit to test whether MTD applies. The relevant figure is normally gross business income before allowable expenses. A business with £55,000 of turnover and £30,000 of expenses can therefore fall within MTD even though its profit is only £25,000.

Landlords must apply the same gross-income principle to property receipts. Where a property is jointly owned, the individual landlord’s share of the property income generally counts towards their qualifying income. For quarterly updates from jointly let property, HMRC permits the taxpayer to report income and expenses or income only, with omitted expenses added after the tax year under the prescribed process.

Someone who is both a sole trader and landlord must combine the gross amounts. For example, £32,000 of business turnover plus £21,000 of rental income gives qualifying income of £53,000. The person may need separate digital records and updates for the different income sources even though the threshold test uses their combined total.

Taxpayers can use our self-employed tax calculator to estimate Income Tax and National Insurance on business profit. The calculator helps with budgeting, but MTD eligibility must still be tested using gross qualifying income rather than the calculated taxable profit.

Benefits of Making Tax Digital

Maintaining records throughout the year can reduce the amount of work left until the January filing season. Regular transaction entry also makes missing invoices, duplicated costs and incorrect categories easier to identify while the information is recent. These are potential benefits rather than guarantees, because inaccurate automation can reproduce errors just as quickly as manual records.

Quarterly updates may provide a more current estimate of the tax arising from business and property income. This can support cash-flow planning, particularly for people whose income changes significantly during the year. The estimate will be less reliable until all other income, reliefs, allowances and year-end adjustments are included.

Software features such as receipt capture, invoicing and bank feeds can reduce repetitive data entry. They can also create a clearer audit trail for the taxpayer or accountant. However, software cost, setup time, data security, support and the ability to export records should all be considered before choosing a platform.

Penalties for MTD Non-Compliance

HMRC’s MTD penalty guidance confirms that the new submission and payment rules apply from the tax year in which a taxpayer joins MTD. Previous tax years remain under the earlier penalty system. A person joining on 6 April 2026 must therefore still deal with the 2025/26 return under the rules applying to that earlier year.

HMRC will not award penalty points for quarterly updates submitted late during 2026/27. The updates must still be completed before the annual return can be submitted, and late-return penalties continue to apply. This transitional treatment does not cancel digital record-keeping or reporting responsibilities.

For later tax years, missing a quarterly deadline normally produces one penalty point. The threshold for taxpayers with quarterly obligations is four points, at which stage a £200 penalty is charged. A further £200 penalty can apply for every additional missed submission while the taxpayer remains at the threshold.

The annual return and payment deadline remains 31 January after the tax year. Late payment penalties can apply to unpaid balancing amounts, amendments and assessments, while interest can accrue on tax paid late. The new late-payment penalties do not apply to payments on account, although late-payment interest may still be charged.

A penalty may be appealable when the taxpayer has a reasonable excuse, but HMRC considers the facts of each case. Software failure should be documented promptly, and the taxpayer should contact the provider before a deadline where possible. Ignoring an update or assuming an accountant has completed it is unlikely to resolve the underlying obligation.

How to Prepare for MTD for Income Tax

Start by reviewing the Self Assessment return HMRC will use for the threshold test. Add together gross income from every self-employment and property source, including the taxpayer’s share of jointly owned property income where relevant. Do not add employment, dividends, pension income or an individual share of partnership profit to this threshold calculation.

Next, review existing bookkeeping methods and identify any gaps. Confirm that every transaction can be recorded with its date, amount and category, and decide whether an all-in-one product or spreadsheet with bridging software is more suitable. Businesses using a 31 March accounting year should check whether calendar update periods are correctly selected before sending the first update.

• Check whether the £50,000, £30,000 or £20,000 phase applies.
• Confirm whether an automatic, temporary or digital-exclusion exemption is relevant.
• Choose software through HMRC’s recognised-product finder.
• Check that the software supports every business and annual-return income source.
• Arrange access for the tax agent if one will submit updates or the return.
• Authorise the software and complete MTD registration before the mandatory start.
• Set reminders for 7 August, 7 November, 7 February and 7 May.
• Review quarterly figures instead of sending unchecked bank-feed data.
• Keep funds available for the normal Self Assessment payment dates.

An accountant can maintain records, send quarterly updates or submit the annual return, depending on the authority provided. The legal responsibility for accurate and complete information still rests with the taxpayer. Responsibilities should therefore be agreed clearly, including who reviews imported transactions and who monitors deadlines.

MTD should be treated as a change in reporting workflow rather than a new tax charge. Establishing a monthly bookkeeping routine can make the quarterly deadlines easier to manage. Accurate digital records will also make the annual corrections and final tax return more straightforward.
