Making Tax Digital for Income Tax (MTD ITSA) 2026/27
The biggest change to self-employed and landlord tax reporting in a generation begins on 6 April 2026. Making Tax Digital for Income Tax Self Assessment (MTD ITSA) replaces the single annual return with digital record-keeping, four quarterly updates and a final declaration — all through compatible software. It applies first to those with combined self-employment and property income over £50,000, with a £30,000 threshold following in April 2027. This guide explains exactly who is in scope, how the new reporting cycle works, the software and digital records you will need, the new points-based penalties, who is exempt, and a clear step-by-step plan to get ready in good time.
Who Is in Scope from April 2026
MTD ITSA applies from 6 April 2026 to self-employed people and landlords whose combined gross income from self-employment and property exceeds £50,000. The threshold is measured on gross income — turnover and rent before expenses — not on profit. So a sole trader with £40,000 of turnover and £15,000 of rental income is in scope, even if their taxable profit is far lower.
The figure is taken from your most recent Self Assessment return. HMRC writes to taxpayers it believes are in scope, but the duty to check and comply rests with you. If you are below £50,000 in 2026/27, you are not yet required to use MTD ITSA — but the £30,000 threshold in April 2027 will sweep in many more people.
If you are self-employed, the self-employed tax guide covers how your profits are taxed alongside these new reporting rules.
Quarterly Updates and the Final Declaration
The headline change is the move from one annual return to a rolling cycle. During the tax year you send four quarterly updates to HMRC, each a cumulative summary of the income and expenses for your business and property, submitted through your software on the standard quarterly deadlines.
The quarterly updates are running summaries, not full tax calculations. After the tax year ends you complete a final declaration, where you finalise the figures, add any other income (such as employment, dividends or savings interest), claim reliefs and confirm your overall position. The final declaration replaces the old Self Assessment return for these income sources.
Crucially, this changes how you report, not how much tax you pay. Your liability is still calculated on profits using the normal rates and allowances, and payment dates are unchanged.
Compatible Software
You must use HMRC-recognised, MTD-compatible software to keep your digital records and submit the quarterly updates and final declaration. You cannot file MTD ITSA through the old HMRC online Self Assessment form.
Options range from full cloud bookkeeping packages to lightweight apps aimed at landlords and sole traders, plus bridging software that links an existing spreadsheet to HMRC. HMRC publishes a list of compatible products. Choosing and setting up your software before the tax year starts is the single most important preparation step.
Digital Records
MTD ITSA requires you to keep digital records of each item of income and expense — the amount, date and category — in compatible software or a linked spreadsheet, recorded as transactions happen rather than gathered up once a year.
The defining principle is digital linking: data must flow from your records to HMRC without manual re-typing that could introduce errors. You do not have to scan every receipt, but the transaction details must live in your digital records and be kept up to date through the year. In practice this nudges everyone towards continuous bookkeeping.
The New Points-Based Penalties
MTD ITSA uses a points-based penalty system for late submissions. Each late quarterly update or final declaration earns a penalty point. Once you accumulate points up to a set threshold (which depends on your submission frequency), a fixed financial penalty applies, and each further late submission triggers another penalty. Points expire after a sustained period of compliance.
Late payment of tax is dealt with separately, with penalties that increase the longer the tax remains unpaid, plus interest on the outstanding amount. The points approach is designed to be more proportionate than the old automatic fines — an occasional slip does not immediately cost money, but persistent lateness does.
The £30,000 Threshold from April 2027
From April 2027, MTD ITSA extends to self-employed people and landlords whose combined gross income exceeds £30,000. The requirements are identical: digital records, quarterly updates and a final declaration.
If your income sits between £30,000 and £50,000, you have a year's grace — but it is wise to adopt digital record-keeping during 2026/27 so the change is seamless when it lands. Further reductions to the threshold are expected in later years, so MTD ITSA will eventually reach the majority of sole traders and landlords.
Exemptions
Some people can be exempt. The main route is digital exclusion — where it is not reasonably practicable to use the software because of age, disability, remoteness of location or religious grounds. Certain trustees, personal representatives and other specific groups are also outside the scope.
You must apply to HMRC for an exemption; you are not automatically exempt simply because you find software difficult. Until an exemption is granted, you should plan to comply in full.
How to Prepare: 5 Steps
- Check your scope: add together gross self-employment and property income; if over £50,000, you are in from April 2026 (£30,000 from April 2027).
- Choose software: pick HMRC-recognised MTD-compatible software, or bridging software for your spreadsheet, and set up your income sources.
- Keep digital records: record income and expenses digitally as they happen, from the start of the tax year.
- Submit quarterly: send each quarterly update through your software on the standard deadlines.
- Final declaration: after the year-end, finalise figures, add other income and reliefs, and submit the final declaration.
