What Is Making Tax Digital? The Complete Guide for UK Small Businesses (2026)
What Is Making Tax Digital? The Complete Guide for UK Small Businesses (2026)
Making Tax Digital (MTD) is HMRC's programme to replace paper-based tax reporting with real-time, software-driven submissions. If you're a sole trader or landlord earning over £50,000, MTD for Income Tax applied to you from 6 April 2026. If you're below that threshold, it's coming — the question is when, and whether your records are in any shape to handle it.
This guide cuts through the confusion: what MTD actually requires, who it affects, what the quarterly deadlines are, what happens if you miss one, and which software genuinely makes compliance manageable.
Receipts are the foundation of MTD compliance. Dext captures them automatically from email, photos, and bank feeds — so your quarterly submissions are ready without the last-minute scramble.
MTD in Brief: Two Taxes, Two Timelines
Making Tax Digital currently covers two taxes:
- MTD for VAT — mandatory for all VAT-registered businesses since April 2022. HMRC's old VAT portal closed in November 2022. If you're VAT-registered and still submitting returns, you're already operating inside MTD.
- MTD for Income Tax Self Assessment (MTD ITSA) — the change that affects sole traders and landlords. This is what most of the current debate is about, and what this guide focuses on.
MTD for Corporation Tax has been consulted on but has no confirmed start date. For now, limited companies are not affected.
Who Does MTD for Income Tax Apply To?
MTD ITSA affects sole traders and landlords whose qualifying income — self-employment income plus property income, measured gross before expenses — exceeds a rolling threshold. HMRC is introducing it in three phases:
| Phase | Start Date | Qualifying Income Threshold | Estimated Taxpayers Affected |
|---|---|---|---|
| Phase 1 | 6 April 2026 | Over £50,000 | ~864,000 |
| Phase 2 | 6 April 2027 | Over £30,000 | ~1,077,000 additional |
| Phase 3 | 6 April 2028 | Over £20,000 | ~975,000 additional |
By April 2028, approximately 2.9 million sole traders and landlords will be inside MTD ITSA. General partnerships are expected to follow, but no confirmed date has been set. The threshold is based on gross qualifying income, not taxable profit — if your turnover exceeds £50,000 even after a loss-making year, MTD still applies.
There is a digital exclusion exemption for people who genuinely cannot use computers due to age, disability, or religious reasons. In practice, this applies to a very small number of taxpayers and requires HMRC approval.
What MTD for Income Tax Actually Requires You to Do
Under MTD ITSA, the annual Self Assessment tax return is replaced by a combination of quarterly updates throughout the year and a Final Declaration at year-end. The underlying record-keeping requirement runs all year, not just at submission time.
Quarterly Updates
You submit a summary of income and expenses to HMRC four times a year using MTD-compatible software. The deadlines for the 2026–27 tax year are:
- 7 August 2026 — for the quarter ending 5 July 2026
- 7 November 2026 — for the quarter ending 5 October 2026
- 7 February 2027 — for the quarter ending 5 January 2027
- 7 May 2027 — for the quarter ending 5 April 2027
These are summaries, not detailed receipt-by-receipt returns. HMRC receives your income and expense totals by category — not scanned copies of every invoice. The underlying records stay in your software and must be available for inspection if HMRC asks.
The Final Declaration
After the tax year closes on 5 April, you submit a Final Declaration by 31 January — the same deadline as the current Self Assessment tax return. This is where you finalise your figures, add any additional income sources (savings interest, dividends, capital gains), and confirm your tax liability for the year. It replaces the Self Assessment return for the income sources covered by MTD.
A correction to make clear: many older articles still refer to an "End of Period Statement" (EOPS) as a separate requirement. The EOPS was permanently abolished following the 2023 Autumn Statement. It no longer exists under the current MTD rules. If a guide you're reading mentions submitting an EOPS, it hasn't been updated — disregard that requirement.
What "Digital Links" Means in Practice
MTD requires a digital link between your records and the figures you submit to HMRC. The rule is simple: no manual re-typing of numbers between systems. If a figure moves from one place to another, it must do so digitally.
Acceptable digital links include:
- Cloud accounting software where data flows directly from bank feeds to the submission
- Spreadsheet formulas feeding a bridging software tool
- CSV exports imported into compatible software
- API connections between receipt capture tools and accounting packages
What is not acceptable: reading a figure from a bank statement and typing it into a spreadsheet. Even copying and pasting a number between applications technically breaks the digital link requirement. This matters most for sole traders who currently manage books in a spreadsheet from paper records.
HMRC-Approved Software: What Are Your Options?
HMRC does not provide a free government portal for MTD ITSA submissions — you must use third-party software. There are currently over 50 HMRC-recognised products. Our complete guide to HMRC-approved MTD software covers the full list, but the main options break into two categories.
Full Cloud Accounting Software
These handle record-keeping, bank feeds, quarterly submissions, and the Final Declaration in one place. The main HMRC-recognised options for UK sole traders:
- Xero — from £18/month (Ignite plan). Strong bank feeds, solid mobile app, and popular with bookkeepers managing multiple clients. See our Xero vs QuickBooks comparison for a detailed head-to-head.
- QuickBooks — from £10/month (Simple Start). HMRC-recognised with MTD ITSA submissions included. Lower entry price than Xero, slightly less polished interface.
- Sage Accounting — from £15/month. UK-based company, HMRC-recognised, and well-supported for sole traders. See our Sage vs Xero vs QuickBooks comparison for a full assessment of all three.
- FreeAgent — free for NatWest, RBS, and Mettle business account holders; £19/month otherwise. Purpose-built for UK sole traders and freelancers. Read our FreeAgent review for the full picture on whether it's genuinely free for you.
- QuickFile — free tier available for businesses under a certain transaction volume. UK-specific, well-regarded by accountants, and HMRC-recognised for MTD ITSA.
For sole traders who want to automate as much of this as possible, pairing cloud accounting software with a receipt capture tool means your receipts, invoices, and bank transactions are all categorised before they reach the quarterly summary. Our guide to building a complete AI bookkeeping stack for under £60/month shows how this fits together in practice.
Not all compliant software costs money. Starling Bank includes free MTD ITSA quarterly submission tools with its sole trader account, and several other platforms offer free tiers. For a current list of the best free options and a comparison of what each covers, see our Starling Accounting review and our guide to the best free bookkeeping tools for UK sole traders.
Bridging Software
If you want to keep using a spreadsheet for day-to-day bookkeeping, bridging software connects your spreadsheet to HMRC's MTD systems. Products like 123 Sheets (free tier available) and VitalTax handle the quarterly submission without requiring a full software switch.
Bridging software costs roughly £5–£30/month — less than full cloud accounting. The trade-off: it doesn't validate data quality, and you still need to maintain a properly linked spreadsheet throughout the year. For most sole traders whose income is growing, the move to full cloud accounting tends to pay for itself in time saved quickly. Our guide on automating your bookkeeping with AI explains where the biggest time savings come from.
The MTD ITSA Penalty Regime
HMRC uses a points-based penalty system for late quarterly submissions:
- Each late quarterly update earns 1 penalty point
- Accumulate 4 points and HMRC issues a flat £200 penalty
- Every further late submission after that triggers an additional £200 fine
- Points expire after 24 months if your compliance record is clean in the intervening period
HMRC has confirmed a soft landing for the 2026–27 tax year: late quarterly updates won't trigger penalty points during the first year, giving newly mandated businesses time to adapt. This soft landing does not apply to the Final Declaration — late payment penalties and interest on overdue tax apply from day one, exactly as under current Self Assessment rules.
