Making Tax Digital for the Self-Employed: The Complete 2026 Preparation Guide

Making Tax Digital for Income Tax (MTD for IT) went live on 6 April 2026, and if you are a sole trader with qualifying income above £50,000 you must now keep digital records and submit four quarterly updates to HMRC, followed by a final declaration each January, rather than relying on the annual self-assessment return alone. For those below the current threshold, mandatory entry is coming: the rollout extends to income above £30,000 from April 2027 and above £20,000 from April 2028. The direction of travel is clear, and preparation now makes the transition considerably less painful. This guide is written by Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice serving the self-employed.

Key Takeaways

• Making Tax Digital for Income Tax went live on 6 April 2026 for sole traders with qualifying income above £50,000.
• The threshold falls to £30,000 from April 2027 and to £20,000 from April 2028; general partnerships remain outside the current timetable.
• Qualifying income is your combined gross income from self-employment and UK property, before any expenses or allowances.
• You must submit four quarterly updates per tax year, due 5 August, 5 November, 5 February, and 5 May.
• A final declaration confirms your tax liability and is due by 31 January following the tax year; for 2026/27 that deadline is 31 January 2028.
• You must use HMRC-recognised software; a raw spreadsheet only satisfies the rules when combined with bridging software that creates the HMRC connection.

What Is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax is HMRC's programme to move income tax reporting onto a digital, real-time basis. Under MTD for IT, qualifying taxpayers must:

• Keep digital records of their income and expenses using HMRC-compatible software
• Submit four quarterly updates per tax year directly to HMRC through that software
• Complete a final declaration by 31 January following the end of the tax year

The quarterly updates are not tax returns in the traditional sense. They are summaries of your business income and expenditure for that quarter, submitted cumulatively to HMRC's systems. They do not generate a tax bill on their own. The final declaration is where you confirm the totals, add any additional income sources, claim reliefs and allowances, and crystallise your tax liability.

MTD for IT replaces the annual self-assessment tax return for income that falls within scope. It does not replace self-assessment entirely where you have income outside the MTD regime, such as rental income below the threshold or employment income.

Who Is in Scope for MTD and When?

You are in scope for MTD for Income Tax based on your qualifying income, which means your gross income from self-employment and UK property combined, before any expenses or allowances. The rollout follows a staged timetable:

From 6 April 2026: Sole traders and landlords whose qualifying income exceeded £50,000 in a previous tax year must comply. If your gross self-employment income was, say, £55,000 in 2024/25, you are in MTD for IT from 6 April 2026.

From April 2027: Those with qualifying income above £30,000 join the regime.

From April 2028: Those with qualifying income above £20,000 join.

No confirmed date has yet been set for those earning below £20,000, and general partnerships remain outside the current timetable altogether, though HMRC has indicated they will be brought in at a later stage.

If you have multiple sources of qualifying income, they are added together for the threshold test. A sole trader with £35,000 from their trade and £20,000 from a rental property has qualifying income of £55,000 and is therefore in scope from 6 April 2026.

What Do Quarterly Updates Actually Require?

Each quarterly update requires you to report the income received and expenses incurred during a three-month period, using HMRC's categories, submitted directly through your software. Each tax year is divided into four MTD quarters. Under the standard quarterly periods, the deadlines for submitting updates are:

• Quarter 1 (6 April to 5 July): submission due by 5 August
• Quarter 2 (6 July to 5 October): submission due by 5 November
• Quarter 3 (6 October to 5 January): submission due by 5 February
• Quarter 4 (6 January to 5 April): submission due by 5 May

Each update requires you to report the income received and expenses incurred during that period, using the categories set out by HMRC. Your software sends this directly to HMRC through an Application Programming Interface connection.

A practical example: a freelance graphic designer with annual revenues of £65,000 must submit their first quarterly update by 5 August 2026, covering income and expenses from 6 April to 5 July. If their income in that quarter was £18,000 and their allowable expenses were £3,200, they submit those figures. No tax is paid at this stage. The update is cumulative, meaning each subsequent quarter builds on the previous one.

Penalties apply for late or missing updates, so building the quarterly submission into your regular bookkeeping routine is important rather than leaving it to the deadline.

How Do You Choose the Right Software for MTD for IT?

You must use a product that has been recognised by HMRC for Making Tax Digital self-employed 2026 purposes, because HMRC does not produce its own MTD-compatible software. A list of approved software is available on the HMRC website.

Commonly used options include cloud bookkeeping packages that many sole traders may already be familiar with. The key requirements for your chosen software are that it must:

• Allow you to record income and expenses digitally
• Categorise transactions in line with HMRC's requirements
• Submit quarterly updates and the final declaration directly to HMRC

Spreadsheets can only be used in conjunction with bridging software that creates the HMRC connection. A raw spreadsheet alone does not satisfy the digital record-keeping requirement.

When assessing software, consider how it handles bank feeds (automated imports of transactions save considerable time), whether it supports multiple income sources, and what its cost implications are. Some software providers offer specific MTD for IT plans that are simpler than full accounting packages.

What Is the Final Declaration and When Is It Due?

The final declaration is the submission, due by 31 January following the end of the tax year, in which you confirm your figures and crystallise your tax liability. For the 2026/27 tax year, that deadline is 31 January 2028. You complete it after the fourth quarterly update.

The final declaration allows you to confirm or adjust the figures submitted across the four quarters, add income not covered by MTD (such as dividends or bank interest), and claim any remaining reliefs and allowances such as the trading allowance, pension contributions, or personal allowance adjustments. It is the mechanism through which your actual tax liability for the year is confirmed and becomes payable.

The payment deadline for the tax due under MTD for IT remains 31 January following the tax year, in line with the existing self-assessment payment timeline.

Frequently Asked Questions

When did Making Tax Digital start for the self-employed?

Making Tax Digital for Income Tax went live on 6 April 2026 for sole traders with qualifying income above £50,000. The threshold then extends to those with income above £30,000 from April 2027 and above £20,000 from April 2028. General partnerships remain outside the current timetable.

What counts as qualifying income for MTD?

Qualifying income for MTD means your gross income from self-employment and UK property combined, before any expenses or allowances. If you have multiple sources, they are added together for the threshold test. A sole trader with £35,000 from their trade and £20,000 from a rental property has £55,000 of qualifying income.

How often do self-employed people report under MTD?

Self-employed individuals in scope submit four quarterly updates per tax year, due 5 August, 5 November, 5 February, and 5 May, followed by a final declaration by 31 January. The quarterly updates are cumulative summaries of income and expenses and do not generate a tax bill on their own.

Can I still use a spreadsheet under Making Tax Digital?

Spreadsheets can only be used in conjunction with bridging software that creates the connection to HMRC. A raw spreadsheet alone does not satisfy the digital record-keeping requirement. HMRC does not produce its own MTD-compatible software, so you must use a product recognised by HMRC, listed on the HMRC website.

When is the final declaration due for the 2026/27 tax year?

The final declaration for the 2026/27 tax year is due by 31 January 2028. You complete it after the fourth quarterly update to confirm or adjust your figures, add income not covered by MTD such as dividends or bank interest, and claim reliefs and allowances. The tax due is also payable by that date.
