Making Tax Digital for Income Tax: landlords and the self-employed

Updated for Budget 2026. Checked against GOV.UK, October 2026.

Making Tax Digital (MTD) for Income Tax is a new way to do Self Assessment if you're a sole trader or landlord. You keep digital records, send short updates to HMRC every 3 months, and file your tax return through software. It's coming in stages, based on your income from self-employment and property before expenses.

Who has to use it

You need to use MTD for Income Tax if all of these apply:

Partnerships don't need to use it yet. HMRC will set out a timeline later.

What counts as qualifying income

Qualifying income is your total self-employment and property income before expenses (your turnover and gross rents). HMRC checks it from your tax return for the year before.

Example

You earn £40,000 from your job. You also get £18,000 a year in rent and take £14,000 from a weekend business. Your qualifying income is £18,000 + £14,000 = £32,000. Your salary doesn't count. If that's your 2025-26 figure, it's over £30,000, so you'd start MTD on 6 April 2027.

When it starts for you

Your qualifying income on this year's returnIs more thanYou use MTD from
2024-25£50,0006 April 2026
2025-26£30,0006 April 2027
2026-27£20,0006 April 2028

So the 2025-26 return you're doing now (due 31 January 2027) is the one HMRC checks for April 2027. If your income is over the threshold, HMRC should write to you. If you don't get a letter, it's still your job to check and sign up.

Quick check: when do I start?

Enter your self-employment turnover plus gross property income (your share), before expenses. Leave a year blank if you don't know it yet. Nothing is stored or sent anywhere.

What you'll have to do

1. Use compatible software

HMRC doesn't provide software. You choose a commercial product that works with MTD for Income Tax. Some create your records for you (for example by linking to your bank account or scanning receipts). Others, called "bridging software", connect to a spreadsheet you already keep. GOV.UK has a tool to find software.

2. Keep digital records

Only for your self-employment and property income and expenses. Each record needs the amount, the date and the category, using the same categories as Self Assessment.

3. Send quarterly updates

A quarterly update is a summary of your income and expense totals, worked out by your software. It isn't a tax return and you don't make tax adjustments. Each update covers the tax year so far, so you can correct mistakes in the next one. You send one for each business, even if nothing happened that quarter.

Update period (standard)Deadline
6 April to 5 July7 August
6 April to 5 October7 November
6 April to 5 January7 February
6 April to 5 April7 May (the following tax year)

If your accounts run from 1 April to 31 March, you can choose "calendar" periods instead (ending 30 June, 30 September, 31 December and 31 March). The deadlines are the same. After each update you get an estimate of your tax bill.

4. Submit your tax return

After the year ends, you check your figures, add any other income (such as your job, savings or dividends) and reliefs, then submit your tax return through your software. The deadline is still 31 January, and so is paying your tax. You still send one return a year.

Penalties

Joining in April 2026: there are no penalties for missing a quarterly update deadline in the 2026-27 tax year. You still have to send them before you can file your return.

Joining in April 2027: Budget 2026 announced that HMRC won't give late submission penalty points for quarterly updates for the 2027-28 tax year. Again, you still need to send them before you can file.

Once you're in MTD, new penalties replace the old ones:

Your 2025-26 return still uses the current penalties, even if you join MTD in April 2026.

Exemptions

If you're exempt, you keep filing a normal Self Assessment return.
