Making Tax Digital (MTD) Complete Guide UK 2026: Everything You Need to Know

Published: 2026-03-08 · Updated for the April 2026 deadline

⏰ MTD for Income Tax starts April 2026. If you're self-employed or a landlord with income over £50,000, you need compatible software and digital records in place before the new tax year begins. Less than a month to go.

Making Tax Digital is the biggest change to UK tax reporting in a generation. Instead of filing one annual tax return, you'll submit quarterly digital updates to HMRC using approved software.

This guide covers who's affected, what changes, what software you need, and a practical action plan to get ready.

What is Making Tax Digital?

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) requires self-employed individuals and landlords to:

  1. Keep digital records of all business income and expenses
  2. Submit quarterly updates to HMRC through compatible software
  3. Submit a final declaration at year end (replacing the annual tax return)

The aim is to reduce errors, give HMRC more timely data, and give taxpayers a clearer picture of their tax position throughout the year.

Am I affected?

You must join MTD from April 2026 if:

From April 2027: the threshold drops to £30,000.

Qualifying income means your gross income from self-employment and/or property — before expenses. It's the total turnover, not your profit.

Quarterly update deadlines

Under MTD, the tax year is split into four quarters:

QuarterPeriodUpdate deadline
Q16 April – 5 July7 August
Q26 July – 5 October7 November
Q36 October – 5 January7 February
Q46 January – 5 April7 May
Final declaration31 January (following year)

Each quarterly update is a summary of income and expenses for that period. It doesn't need to be perfect — you can make adjustments in later quarters or the final declaration.

What software do I need?

You must use software that is HMRC-recognised for MTD ITSA. This means it can connect to HMRC's systems via their API to submit your updates digitally.

Your options:

OptionCostBest for
HMRC's free MTD toolFreeVery simple affairs (limited features)
FreeAgent~£15-25/monthFreelancers and sole traders
Xero~£15-35/monthSmall businesses with multiple income streams
QuickBooks~£12-30/monthSole traders who want invoicing built in
Sage~£12-25/monthTraditional businesses, bookkeeper-friendly
Bridging software£5-15/monthSpreadsheet users who want to keep their current setup

Full comparison: free vs paid MTD software →

⚠️ Spreadsheets alone aren't enough. You can use a spreadsheet to track your records, but you need bridging software to submit to HMRC. The submission must go through their API — you can't email or upload a spreadsheet.

Digital record-keeping requirements

Under MTD, your digital records must include:

What "digital" means: records must be created, stored, and maintained digitally. You can photograph paper receipts and store them digitally, but the record of the transaction itself must be in your software or spreadsheet — not a shoebox of paper.

The new penalty system

MTD introduces a points-based penalty regime (replacing the old fixed penalties):

Late submission penalties

Late payment penalties

💡 Grace period: HMRC has confirmed a lighter touch in the first year of MTD, with more support and fewer penalties while people adjust. But don't rely on this — build good habits from day one.

Action plan: how to prepare

If you earn over £50,000 (must join April 2026)

  1. Now: Choose your MTD software and sign up
  2. Now: Start entering current transactions to learn the software
  3. March 2026: Ensure all 2025/26 records are in the software
  4. 6 April 2026: Begin recording in MTD format from day one of the new tax year
  5. 7 August 2026: Submit your first quarterly update

If you earn £30,000-£50,000 (must join April 2027)

  1. Now: Start researching software options
  2. Summer 2026: Choose software and begin transition
  3. January 2027: Have software set up and tested
  4. 6 April 2027: Begin MTD reporting

If you earn under £30,000

You're not currently required to join MTD, but moving to digital record-keeping is still good practice. It makes your annual self-assessment easier and prepares you in case the threshold drops further.

Costs to budget for

MTD adds ongoing software costs that many self-employed people haven't had before:

ItemTypical annual cost
MTD software subscription£60-£360
Accountant support (if needed)£150-£500
Time spent on quarterly updates4-8 hours/year (if records are up to date)

The good news: software subscription costs are an allowable business expense — you can deduct them from your taxable profit.

Common questions

Can my accountant do it for me?

Yes. Your accountant can submit quarterly updates on your behalf using agent services. But you still need to keep digital records and provide timely information — they can't submit what they don't have.

What if I have both self-employment and property income?

You submit updates for each income source. Your software should handle multiple income streams. Both count towards the qualifying income threshold.

Will I still need to file a self-assessment return?

The annual tax return is replaced by the final declaration, which serves the same purpose but is submitted through your MTD software. The deadline remains 31 January.

I'm VAT registered — do I need to do both?

If you're already using MTD for VAT, you'll need MTD for Income Tax as well if your income qualifies. They're separate obligations with separate submissions, though some software handles both.
