MTD ITSA and Landlords with a Self-Employed Business: How the Rules Combine

If you run a sole trade and let property, Making Tax Digital for Income Tax adds your trading and rental income together for the entry test, then makes you report each one separately. That rule catches many people who assumed they were below the threshold, because a modest self-employment and a single rental property can combine to exceed £50,000 of qualifying income where neither would alone. Making Tax Digital self-employed 2026 rules took effect from 6 April 2026, and the first quarterly deadline has already passed for those in scope. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, finds the reporting burden routinely underestimated by people holding both income types. This article explains how the two sets of rules interact, how qualifying income is measured, how many submissions you owe, and what to do before the next deadline.

Key Takeaways

• Making Tax Digital for Income Tax applies from 6 April 2026 to sole traders and landlords whose combined qualifying income exceeded £50,000 in the 2024/25 tax year, falling to £30,000 from April 2027 and £20,000 from April 2028.
• Qualifying income is gross income before expenses, so a sole trader with £38,000 of turnover and £19,200 of rents has £57,200 of qualifying income and is inside MTD.
• A person with both a sole trade and a property business submits two sets of quarterly updates, giving eight submissions a tax year plus one final declaration.
• Quarterly update deadlines for 2026/27 are 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027, with the final declaration due by 31 January 2028.
• Making Tax Digital changes how you report, not when you pay: income tax remains payable on 31 January and 31 July, and payments on account continue unchanged.

How does Making Tax Digital work if you are self-employed and a landlord?

Making Tax Digital for Income Tax treats a sole trade and a property business as two separate businesses that share one entry test. HMRC adds the gross income from every self-employment and every property source together to decide whether you are in scope, but once you are in, each business is reported in its own right with its own digital records and its own quarterly updates.

The practical effect is that the two income types never merge. A consultant who also lets two flats keeps one set of digital records for the consultancy and another for the lettings, and files a quarterly update for each. An overseas property business counts separately again, giving a landlord with a holiday flat abroad a third reporting stream.

The final declaration is where everything comes back together. It replaces the self-assessment tax return, pulls in the figures from every business, and adds anything MTD does not cover, such as employment income, dividends, savings interest and pension contributions. Only at that stage is a single income tax liability calculated.

How is qualifying income calculated when you have two income sources?

Qualifying income is total gross income from self-employment and property before allowable expenses, measured against the tax year two years earlier. For entry on 6 April 2026, HMRC looked at the 2024/25 self-assessment return.

Gross is the word that catches people out. A landlord thinks in terms of profit after mortgage interest and repairs, while HMRC counts the rent that arrives; a sole trader thinks in terms of drawings, while HMRC counts turnover.

Take a self-employed graphic designer with £38,000 of turnover and business costs of £11,000, alongside two rental properties producing £19,200 of gross rents with £13,000 of mortgage interest and running costs. The taxable profit across both is £33,200, comfortably below the threshold. Qualifying income, however, is £38,000 plus £19,200, or £57,200, which is above £50,000 and puts both businesses into MTD ITSA from 6 April 2026. A second designer with £34,000 of turnover and £14,000 of rents has £48,000 of qualifying income and joins from April 2027 instead.

Employment, pension, dividend and savings income is excluded from the test entirely, so a person with a £70,000 salary and £22,000 of rents is not in MTD until April 2028. For a full overview of the timetable and what it means for a sole trade, see our guide to Making Tax Digital for the self-employed.

How many quarterly returns does a self-employed landlord submit?

A person with one sole trade and one property business submits eight quarterly updates a tax year, four for each business, followed by a single final declaration. Add a second trade or an overseas let and the count rises by four again.

Each quarterly update is a cumulative summary of income and expenses for that business, categorised as on the self-employment or property pages of a tax return. It is not a tax calculation and nothing is payable on submission. Because updates are cumulative, an error in an earlier quarter is corrected simply by filing the next one with the right figures.

Landlords get one useful relaxation. Where property is jointly owned, HMRC allows the joint owner to report only their share of the gross rents quarterly and to bring in the expenses at the final declaration instead, which removes a good deal of work for couples who own rental property together.

What are the MTD deadlines for 2026/27?

The quarterly returns self-employed taxpayers and landlords must file for 2026/27 are due on 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027, one month after each quarter end. The standard quarters run 6 April to 5 July, 6 July to 5 October, 6 October to 5 January, and 6 January to 5 April.

Software can be set to use calendar quarter ends of 30 June, 30 September, 31 December and 31 March instead, which suits anyone whose bookkeeping already runs to month end. The election must be made before the first update of the tax year and applies to all of your businesses, so a sole trade and a property business cannot use different quarter dates.

The final declaration for 2026/27 is due by 31 January 2028, and the balancing payment and first payment on account for 2027/28 fall due on the same day. Late quarterly updates attract points under the points-based penalty regime rather than an immediate fine, with a £200 penalty once four points are reached.

How should you prepare before your next quarterly update?

The most important preparation step is separating the two businesses in your records before the quarter closes, because MTD software cannot split a mixed bank account for you. Open a dedicated account for rents and property costs, and keep trading receipts and payments away from it.

Check that your software appears on HMRC's list of compatible products and that it supports multiple businesses under one taxpayer, since some cheaper packages handle a sole trade well and property poorly. Authorise it with HMRC, confirm the quarter end convention you want, and run a test submission early rather than in the final week.

Treat the quarterly rhythm as a benefit rather than a chore. A trader and landlord who reconciles both businesses every three months has a reliable profit figure four times a year, which makes tax payments predictable and leaves real time to act before 5 April.

Frequently Asked Questions

Do I have to file separate MTD returns for my self-employment and my rental income?

Yes. Making Tax Digital for Income Tax treats a sole trade and a property business as two separate businesses, each with its own digital records and its own quarterly updates. A person with one trade and one UK property business files eight quarterly updates a tax year, four for each business, then brings everything together in a single final declaration by 31 January.

Is the £50,000 MTD threshold based on profit or turnover?

The threshold is based on gross income before expenses, not profit. HMRC adds together turnover from every self-employment and gross rents from every property business. A sole trader with £38,000 of turnover and £19,200 of rents has qualifying income of £57,200 and is inside MTD, even though the combined taxable profit may be well under £35,000.

Does salary or dividend income count towards the MTD threshold?

No. Only self-employment turnover and property income count towards the qualifying income test. Employment income, pension income, dividends, savings interest and capital gains are excluded. Someone earning £70,000 as an employee with £22,000 of rental income has qualifying income of £22,000 and joins Making Tax Digital from April 2028 under the £20,000 threshold.

When are the quarterly updates due for the 2026/27 tax year?

Quarterly updates for 2026/27 are due on 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027. Each covers the quarter ending one month earlier, running from 6 April to 5 July and so on. The final declaration replacing the self-assessment tax return is due by 31 January 2028.

Do I still pay my tax on 31 January under Making Tax Digital?

Yes. Making Tax Digital changes how income tax is reported, not when it is paid. Balancing payments remain due on 31 January and payments on account on 31 January and 31 July. Quarterly updates carry no payment obligation, though the running estimate they produce makes budgeting for those dates considerably easier.

Conclusion

The combination of a sole trade and rental property is the single most common reason people find themselves unexpectedly inside Making Tax Digital, because the £50,000 test looks at gross income across both. If that is you, the obligation is eight quarterly updates a year plus a final declaration, and it is already live. Check your 2024/25 return, add the turnover to the gross rents, and if the total clears £50,000, get the two businesses separated in your records before the November deadline.
