Making Tax Digital for Tradespeople: What You Need to Know in 2026

Making Tax Digital (MTD) is HMRC's programme to move the UK tax system fully online. For most tradespeople it means submitting quarterly digital updates instead of a single annual tax return — and it is already live for higher earners.

What is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) requires sole traders and landlords to keep digital records and submit quarterly updates to HMRC through compatible software. At the end of the tax year you submit a final declaration instead of a traditional Self Assessment return.

It is not optional. Once you hit the income threshold, you must comply or face penalties.

Who does it apply to — and when?

The rollout is staged by income level:

If your combined self-employment and rental income exceeds £50,000, you are already required to comply. If you are between £30,000 and £50,000, you have until April 2027.

MTD for VAT has been mandatory since April 2022 for all VAT-registered businesses, so if you are VAT-registered you are already submitting through compatible software.

What does quarterly submission actually mean?

Instead of one annual return, you submit four quarterly updates to HMRC:

• Quarter 1: April to June (due 5 August)
• Quarter 2: July to September (due 5 November)
• Quarter 3: October to December (due 5 February)
• Quarter 4: January to March (due 5 May)

Each update is a summary of income and expenses for that period — not a full tax calculation. HMRC uses them to give you an estimated tax position throughout the year. The final declaration at year end adjusts everything and confirms your actual liability.

The quarterly updates are simpler than a Self Assessment return, but they require your records to be up to date throughout the year rather than scrambled together in January.

What software do you need?

You must use HMRC-recognised software. The list includes major accounting platforms (FreeAgent, QuickBooks, Xero, Sage) as well as purpose-built tools for tradespeople.

Sleepless Tradesman is MTD-compatible and built for trades — it connects to HMRC directly and lets you submit from the same place you manage jobs, quotes, and invoices.

The software must be able to:

• Store digital records of income and expenses
• Connect directly to HMRC's systems
• Submit quarterly updates and the final declaration

Spreadsheets alone do not qualify unless they are linked to approved bridging software.

Do I still need an accountant?

MTD does not remove the need for an accountant, but it does change the relationship. Instead of handing over a box of receipts once a year, you share live data throughout the year. Many tradespeople find this means smaller, more predictable accounting bills — and fewer surprises at payment on account time.

What happens if I miss a deadline?

HMRC operates a points-based penalty system for MTD. Each missed quarterly update earns a point. Reach the threshold (four points for quarterly filers) and you receive a £200 penalty. Persistent non-compliance can lead to further fines.

The best protection is software that reminds you when submissions are due and makes it straightforward to meet the deadline.

Frequently asked questions

Does MTD apply to limited companies? No. MTD ITSA applies to sole traders and partnerships. Limited companies are subject to MTD for Corporation Tax, which is still in consultation and does not have a confirmed start date.

What if my income fluctuates? You are assessed on your actual income for the tax year. If your income drops below the threshold, you may be able to apply to leave MTD — HMRC will confirm the process in those cases.

Can I still use a paper tax return? No. Once you are within MTD, digital submission is mandatory. Paper returns are no longer accepted for those in scope.

Do I need to submit if I have nothing to report in a quarter? Yes. You must submit a nil return for any quarter where you have no income or expenses to report.
