What is Making Tax Digital? A Guide for UK Sole Traders

What is Making Tax Digital?

Making Tax Digital (MTD) is HMRC's programme to modernise the UK tax system through digital, quarterly reporting. Instead of filing one Self Assessment tax return each January, you submit income and expense summaries every three months through HMRC-approved software — followed by a final end-of-year declaration.

MTD already applies to VAT-registered businesses, having been introduced in April 2019 for larger businesses and extended in April 2022. From April 2026, it expands to Income Tax Self Assessment — which directly affects sole traders, freelancers, and landlords above certain income thresholds.

The quarterly updates are not tax payments. They are summaries of your income and expenses so that HMRC can build a more accurate, real-time picture of your tax position throughout the year. The actual tax calculation and settlement happens at the end of the tax year.

Who is Affected by Making Tax Digital — and When?

MTD for Income Tax Self Assessment (MTD ITSA) rolls out in three phases, based on your qualifying income. Qualifying income is your combined gross total from self-employment and UK property — before deducting any expenses:

• April 2026: Sole traders and landlords with qualifying income over £50,000
• April 2027: Those with qualifying income over £30,000
• April 2028 (expected): Those with qualifying income over £20,000

If you have income from more than one source — for example, freelance work plus rental income from a property — both streams count toward the threshold. If your combined qualifying income crosses £50,000, you are in scope from April 2026.

PAYE employment income does not count. If you earn £40,000 through PAYE employment and £25,000 from freelancing, only the £25,000 matters for MTD. HMRC also excludes dividends, savings interest, and pension income from the qualifying income calculation.

What Does MTD for Income Tax Require You to Do?

Once in scope, MTD for Income Tax requires three things:

1. Keep digital records of all income and expenses throughout the year, using HMRC-approved software
2. Submit quarterly updates to HMRC — a summary of your income and expenses for each quarter
3. File a final declaration at the end of the tax year, replacing your current annual Self Assessment return

Quarterly submission deadlines

Quarter	Period covered	Submit by
Q1	6 April – 5 July	7 August
Q2	6 July – 5 October	7 November
Q3	6 October – 5 January	7 February
Q4	6 January – 5 April	7 May

What Software Do You Need for MTD?

You will need software that HMRC officially recognises as MTD-compatible. Spreadsheets alone — including Excel and Google Sheets — are not sufficient for direct submission unless connected via approved bridging software.

The four main options for UK sole traders are:

• FreeAgent — purpose-built for freelancers and sole traders; fully HMRC-recognised; free with qualifying NatWest, RBS, Ulster Bank, or Mettle business accounts
• Xero — feature-rich with strong bank feeds and integrations; best suited to growing businesses needing comprehensive reporting
• QuickBooks — competitive pricing with a dedicated sole trader plan; strong mobile app; full MTD Income Tax support
• Sage — UK-based with a genuinely free tier for sole traders (Sage Sole Trader); good compliance credentials and UK customer support

Paid plans start from around £8 per month for a basic sole trader plan, rising to around £19 per month for more comprehensive packages. FreeAgent and Sage both offer free options in specific circumstances. Prices as of March 2026 — always check provider websites for current pricing.

If you currently use spreadsheets and want to continue doing so, bridging software is also an option. It connects your spreadsheet data to HMRC's MTD system and handles the submission automatically. See our MTD software options guide for a full breakdown of all approaches.

What Are the Penalties for Missing an MTD Deadline?

HMRC uses a points-based penalty system for MTD non-compliance:

• Each missed quarterly submission earns one penalty point
• Reaching four points triggers a £200 financial penalty
• Each additional missed submission after reaching the threshold = a further £200 penalty
• Points reset only after 24 months of full compliance

HMRC has confirmed a soft landing period for 2026/27 — penalty points will not convert to financial penalties during the first year of mandatory MTD. This is intended to give businesses time to adjust. However, it is not a grace period to ignore the process; the habit of quarterly reporting needs to be established before the soft landing ends.

Do You Need to Register for MTD Yourself?

Yes. HMRC will not automatically enrol you into MTD for Income Tax. You need to register yourself through your Government Gateway account. HMRC may write to you ahead of your mandatory start date, but you should not wait for that letter — register proactively and give yourself time to set up and test your software before the deadline.

If you fall into the April 2026 wave (qualifying income over £50,000), you should aim to be registered and set up well before 6 April 2026.

What if Your Income is Under £20,000?

The rules for those earning under £20,000 are still being finalised. HMRC has not confirmed whether MTD will extend to this group or what the lower income limit might be. If your qualifying income is currently under £20,000, you are not required to act now. That said, building good digital record-keeping habits is sensible preparation regardless of whether MTD eventually applies to you.

What to Do Next

If your qualifying income is over £50,000, April 2026 is your mandatory start date. The practical steps are:

1. Confirm your position using the MTD eligibility checker
2. Compare software options using our Software Chooser tool or full software guide
3. Set up your chosen software and connect it to your HMRC Government Gateway account before April 2026
4. Run a trial quarterly submission before the deadline so you are comfortable with the process

If you are below £50,000, you have more time — but the software and habits you choose now will be the same ones you use when your deadline arrives.
