Making Tax Digital is HMRC’s flagship digitalisation programme, and it’s expanding fast. Whether you’re already filing VAT digitally or bracing for MTD for Income Tax, here’s what every small business needs to know right now.
Making Tax Digital (MTD) is HMRC’s programme to modernise the UK tax system. The core idea: businesses must keep digital records and use HMRC-approved software to submit tax returns, replacing manual paper-based processes entirely.
MTD is rolling out in stages. VAT-registered businesses are already in scope. Self-employed individuals and landlords are next, with the most significant deadline coming in April 2026.
Since April 2022, MTD for VAT has applied to all VAT-registered businesses, regardless of turnover. If you’re VAT-registered, you must already be:
If you’re still submitting VAT returns manually through HMRC’s old portal, you are not compliant and could face penalties.
⚠ No manual entry allowedYou cannot enter figures manually into HMRC’s own portal and be MTD compliant. The data must flow digitally from your records into your return. Bridging software (which reads a spreadsheet and submits it via API) is permitted as a short-term solution.
The most significant expansion is MTD for Income Tax Self Assessment (ITSA), which will transform how self-employed people and landlords report their income to HMRC:
| Date | Who it affects | What changes |
|---|---|---|
| April 2026 | Self-employed & landlords with income over £50,000 | Must keep digital records and submit quarterly updates to HMRC, plus an end-of-period statement |
| April 2027 | Self-employed & landlords with income over £30,000 | Same requirements as above |
| TBC (likely 2028) | Those with income over £20,000 | Government has committed to this threshold; date not yet confirmed |
This replaces the traditional single annual Self Assessment return with four quarterly updates per year, plus a final declaration. Quarterly updates don’t mean quarterly tax payments — they’re information submissions. You still pay tax through the normal Self Assessment payment schedule.
HMRC requires you to record each transaction digitally, including: date of the transaction, amount, category (e.g. office costs, travel, materials), and whether it’s income or expenditure. You don’t need to scan every receipt, but you do need the figures captured in compliant software — not in a Word document or an ordinary Excel spreadsheet unless bridging software is used.
HMRC is introducing a new points-based penalty system alongside MTD. Each late or missed submission earns a penalty point. Once you reach the threshold (currently four points for quarterly filers), a £200 financial penalty applies — with further £200 penalties for each subsequent failure. Points expire after two years of full compliance.
📌 What to do this yearEven if the 2026 deadline doesn’t apply to you yet, this is a good moment to: review your current record-keeping, trial one or two MTD-compatible software packages, and speak to your accountant about their MTD migration plan. The businesses that struggle most are those who leave it until six months before the deadline.
HMRC has confirmed plans for MTD for Corporation Tax, but no firm implementation date has been set. Limited company owners should monitor HMRC announcements but are not yet required to act.
