Making Tax Digital 2026: Complete Guide for the Self-Employed and Landlords

Making Tax Digital (MTD) for Income Tax became mandatory on 6 April 2026 for self-employed people and landlords with gross income over £50,000. It is no longer something to prepare for — the first quarterly update was due on 7 August 2026, and the next falls on 7 November 2026.

If you are self-employed, a freelancer, a sole trader, or a landlord in the UK, this guide covers what applies: who is in scope, what you must submit and when, what counts as a digital record, which software you need, and what happens if you miss a deadline.

What Is Making Tax Digital?

Making Tax Digital is HMRC's programme to modernise the UK tax system. Instead of filing one annual Self Assessment return, you keep digital records throughout the year and submit quarterly summaries to HMRC.

MTD for VAT has been mandatory since April 2022. The phase that affects self-employed individuals and landlords — MTD for Income Tax Self Assessment (ITSA) — started in April 2026.

Who Is Affected by MTD for Income Tax?

MTD for ITSA applies to UK individuals with income from self-employment (sole traders, freelancers, contractors) or property (landlords receiving rental income), where combined gross income exceeds the threshold for their phase:

The threshold is gross income, not profit. Turnover from self-employment and gross rental income are added together before any expenses, allowances, or deductions.

Worked example: a freelance designer with £42,000 of self-employment turnover who also receives £12,000 in rent has combined gross income of £54,000. That is above £50,000, so Phase 1 applies — even though their taxable profit after costs is far lower.

The same trap catches landlords hardest, because mortgage interest and agent fees are excluded from the calculation. £55,000 of rent against £48,000 of costs is £55,000 of qualifying income, not £7,000. See our guide to MTD for landlords for the property-specific rules, including how joint ownership is treated.

HMRC determines your threshold from the tax return whose filing deadline fell just before the start of the relevant tax year. For Phase 1 (2026/27), that is your 2024/25 return filed by 31 January 2026.

HMRC will not sign you up automatically — you must register yourself through your Government Gateway account, even if you are already registered for MTD for VAT.

Partnerships Are Not In Scope

If you trade through a partnership, MTD for Income Tax does not currently apply to it. General partnerships, limited partnerships, and LLPs have all been deferred with no mandation date set.

Just as importantly, partnership profit share is not counted in your qualifying income for the threshold test. If you have £35,000 of sole-trader turnover and a £40,000 share of partnership profits, your qualifying income is £35,000 — you are not in Phase 1.

Limited companies are outside MTD for Income Tax entirely; that is MTD for Corporation Tax, which also has no confirmed start date.

The Two Core Submissions

Quarterly Updates

You submit cumulative year-to-date summaries of income and expenses every quarter. These are not tax returns — they are running totals, broken down by category.

Because the updates are cumulative, anything missed in an earlier quarter is picked up automatically in the next one. There is no amendment process to worry about — a receipt you find in October still lands correctly in the Q2 figures.

Each income source files separately. One freelance business plus one rental property means two sets of quarterly updates. UK property and foreign property also count as separate businesses.

Final Declaration

After the fourth quarter, a Final Declaration replaces your Self Assessment return. It pulls together every income source — self-employment, property, employment, dividends, savings, capital gains — and confirms your total tax liability. The deadline is 31 January following the end of the tax year, so 31 January 2028 for 2026/27.

Note: older guides describe a separate End of Period Statement (EOPS) filed before the Final Declaration. That step was removed and its function folded into the Final Declaration. The process is quarterly updates, then Final Declaration — nothing in between.

Digital Record Keeping

Under MTD you must record, digitally, for every business transaction:

• the date
• the amount
• the category of income or expense

Paper records alone are not sufficient. That means MTD-compatible software, or a spreadsheet paired with bridging software.

You are not required to store a digital image of every receipt — the digital requirement applies to the transaction record. But HMRC can request the underlying documents during a compliance check, and the retention rules have not changed: keep records for at least 5 years after the 31 January filing deadline.

Since you need the receipts anyway, capturing them digitally creates the digital record and the supporting evidence in one step. See our guides to VAT record keeping requirements and whether bank statements count as receipts for what HMRC actually expects behind each figure. For what a compliant record looks like transaction by transaction, and whether you need to scan receipts, see MTD digital records explained.

Digital Links

Once data is in your digital records, any transfer between systems or to HMRC must be digital.

Not acceptable:

• Manually typing figures from one system into another
• Copy-pasting between a spreadsheet and accounting software

Acceptable:

• API connections between products
• CSV or structured file imports
• Automated syncs
• Formulas within a single spreadsheet

If you keep records in a spreadsheet, you need bridging software to submit. If you use separate tools for record keeping and filing, the handoff between them has to be one of the acceptable methods above.

What Software Do You Need?

You need MTD-compatible software that can submit quarterly updates and your Final Declaration to HMRC through their API. HMRC maintains an official list of recognised providers and a software finder that filters by your income sources and accounting period.

Options range from full accounting packages (Xero, QuickBooks, FreeAgent, Sage) to lighter tools built for MTD submission, plus free options for simple affairs. HMRC explicitly permits using more than one product — for example one for creating records and sending quarterly updates, another for the tax return. Our MTD software guide walks through the choice.

MTD Penalties

MTD uses a points-based system for late submissions, with a significant concession in the first year:

• Quarterly updates carry no penalty points during 2026/27. Confirmed at Autumn Budget 2025.
• Late annual returns do earn points, this year and after.
• The threshold is 4 points for quarterly filers; reaching it triggers £200, and every further miss costs another £200.
• Late payment penalties apply in full: 3% of tax outstanding at day 15, a further 3% at day 30, then 10% per year charged daily. For your first year in the system you get an extra 15 days before the first charge.
• A £3,000 penalty exists for failure to keep digital records or a break in digital links, though it arises through a compliance check rather than automatically.

What to Do Now

If you are already in Phase 1, the job is keeping the rhythm:

1. Diarise 7 November — the Q2 deadline — our quarterly update checklist walks through the reconciliation
2. Reconcile before you file, not at year end — match each bank transaction to its receipt as you go, so Q2's figures are right first time
3. Fill the Q1 gaps — anything missed in the first quarter can simply be included now, since updates are cumulative
4. Check your software actually submits — a tool that organises records is not the same as one HMRC recognises for filing
5. Confirm who files — if your accountant submits on your behalf, make sure you both know it

If your phase is still ahead, the £30,000 threshold arrives in April 2027 and £20,000 in April 2028. Work through this before then:

1. Confirm your gross income threshold — check your latest return for turnover and gross rents, not profit
2. Choose MTD-compatible software — and check it supports every income source you have
3. Sign up through Government Gateway — HMRC will not enrol you automatically
4. Set up digital record keeping now — scan receipts as they arrive and connect your email so digital receipts are captured without forwarding. Starting early means the mandate is a filing change rather than a filing change plus a bookkeeping overhaul
5. Review your allowable expenses — MTD does not change what is deductible, but quarterly reporting makes gaps more visible. See self-employed expenses, flat rate expenses, and mileage allowance
6. Talk to your accountant — agree who submits quarterly updates, which software they can work in, how you will share records, and whether your workflow needs to change

Preparation Checklist

• Gross income threshold confirmed (Phase 1, 2, or 3)
• MTD-compatible software chosen, covering all income sources
• Signed up for MTD for Income Tax on Government Gateway
• Digital receipt capture in place
• Email connected for automatic receipt capture
• Bank statements reconciled against receipts
• Allowable expense categories reviewed
• Workflow agreed with your accountant
• Quarterly deadlines in the calendar — 7 Aug, 7 Nov, 7 Feb, 7 May

If receipts are the part that breaks down — and for most people they are, because rent and invoices arrive as clean bank lines while costs arrive as paper — MTD-ready record keeping covers how to close that gap.

Making Tax Digital FAQ

Does MTD apply to me if I am self-employed?

Yes, if your combined gross income from self-employment and property exceeds the threshold for your phase — £50,000 from April 2026, £30,000 from April 2027, £20,000 from April 2028. Gross means turnover before expenses.

What is MTD for ITSA?

MTD for Income Tax Self Assessment is the branch of Making Tax Digital that applies to sole traders and landlords. It replaces the annual Self Assessment return with quarterly updates plus a Final Declaration.

Do I need to submit every receipt quarterly?

No. Quarterly updates are summary totals of income and expenses, not individual transactions. You must keep the underlying receipts in case HMRC requests them.

Can I use a spreadsheet for MTD?

Yes, but you need bridging software to submit the data to HMRC digitally. You cannot manually type figures into HMRC's systems.

Do partnerships have to comply?

No. General partnerships, limited partnerships, and LLPs are all deferred with no mandation date. Partnership profit share also does not count towards your personal qualifying income threshold.

Will I be fined for a late quarterly update this year?

Not a penalty point — quarterly updates carry no points during 2026/27. Late payment penalties still apply, and a late annual return still earns a point.

What if my income drops below the threshold?

Once mandated into MTD, you remain in it even if income falls below the threshold in later years. You can apply to HMRC to leave in certain circumstances.

Does MTD replace Self Assessment?

For income covered by MTD (self-employment and property), the quarterly updates and Final Declaration replace the Self Assessment return. Other income types are declared in the Final Declaration.

Can I apply for an exemption?

You can apply on grounds of digital exclusion — age, disability, location without reliable internet, or religious objection. Applications are assessed individually, and this must be requested separately even if you already hold an exemption for MTD for VAT.
