Foreign income and the £50,000 Making Tax Digital threshold

The answer turns on residence, not geography

For a landlord or business owner who straddles the UK and the UAE, the natural question about Making Tax Digital for Income Tax is whether their overseas income drags them over the £50,000 threshold. The instinct is to look at the property: the flat in Dubai, the villa in France, the trade run from abroad, and to ask whether HMRC counts it. That is the wrong place to look. Whether foreign income counts is not decided by where the income arises. It is decided by whether the person was UK resident for the year in question, and residence is settled by the Statutory Residence Test, not by where a home happens to be.

The result is that the same overseas rent counts for one person and not for another, purely because of their residence status. A UK resident is measured on their worldwide property and trading income; a non-resident is measured only on what is declared on a UK return. The building has not moved. The residence has. This note draws that line precisely, because for a corridor client it is the difference between being pulled into quarterly digital reporting by their foreign portfolio and being outside the threshold on their UK income alone.

First, what qualifying income even is

Before residence, one narrowing point that removes most of the anxiety. Qualifying income, the figure tested against the threshold, is only income from self-employment and property. It is measured gross, before expenses, and it does not include other kinds of income at all.

That means foreign dividends, foreign interest, a foreign salary, and an overseas pension never count towards the threshold, for anyone, resident or not, because none of them is trading or property income. A UK resident with a modest UK let and a large portfolio of overseas dividends is not pushed into Making Tax Digital by the dividends, because dividends are outside qualifying income entirely. The only foreign income that can ever be in play is foreign property income and foreign self-employment income. Everything else is beside the point. So the real question narrows to: does foreign property and foreign trading income count, and that is where residence decides the answer.

If you were UK resident: the measure is worldwide

For a UK resident, the qualifying-income calculation is worldwide as regards property and self-employment. HMRC assesses the figure from the Self Assessment return for the relevant year, and for a UK resident that return includes both UK and foreign property income, and UK and foreign self-employment.

HMRC's own example is a person who is a sole trader in the UK and also rents out a property in France; both income sources count towards their qualifying income. Read across to the corridor, a UK resident who lets a property in the UAE counts that UAE rent towards the £50,000 threshold in exactly the same way. For a UK-resident owner with property on both sides, the foreign rent is not a separate matter to be reported elsewhere; it is part of the same qualifying-income total, and it can be the income that lifts them over the line and into quarterly digital reporting when their UK income alone would not.

This catches people who think of their overseas property as outside the UK system because it is taxed, or not taxed, abroad. For a UK resident it is inside the UK system, it is on the UK return, and it is inside the Making Tax Digital calculation.

If you were not UK resident: the measure is UK only

For a non-resident, the calculation is ring-fenced to UK-taxable income. HMRC assesses qualifying income from the UK Self Assessment return, and for a non-resident that return carries UK property income, self-employment income declared on the UK return, and any trade of dealing in or developing UK land. Foreign property income and foreign self-employment that are not declared on the UK return do not count.

HMRC's example is a person tax resident in Spain who rents out a property in the UK and runs a sole trade in Spain; only the UK property income counts towards their qualifying income. The Spanish trade is outside it. Translate that to the corridor and the point is sharp: a landlord resident in the UAE, with a substantial UAE property portfolio and a single UK buy-to-let, counts only the UK buy-to-let towards the threshold. The UAE portfolio, however large, does not enter the calculation, because it is not on the UK return. A non-resident is not measured on their worldwide wealth; they are measured on the slice of income the UK actually taxes.

This is usually good news for the UAE-based owner, and it compounds with the separate deferral available to non-residents. A non-resident landlord is both ring-fenced to their UK income for the threshold and, through the SA109 residence page, deferred from Making Tax Digital until at least April 2027, the mechanism set out in the guide to Making Tax Digital for the non-resident landlord.

Residence is a test, and it is tested year by year

Because everything turns on residence, two further points decide real cases.

The first is that residence for this purpose is not a matter of choice or of where a person feels settled. It is determined by the Statutory Residence Test, the day-counting and connecting-factor framework that decides UK residence for a tax year, examined in the analysis of the Statutory Residence Test. A person who believes they have left the UK but who fails the test is UK resident, and their worldwide property and trading income is in the qualifying-income calculation whether they expected it or not. The residence question has to be answered correctly before the threshold question can be.

The second is timing. HMRC assesses the threshold from the return for the year it uses, and residence is decided year by year. A person part-way through a move between the UK and the UAE can therefore be on the worldwide measure in the year they were UK resident and on the UK-only measure in the year they were not, with the threshold answer changing as the residence answer changes. The year of departure, with its split-year treatment and its SA109 page, is exactly the year where the calculation shifts, and it is the year most likely to be misread. The wider UK tax position of a person living in Dubai, of which this forms one part, is set out in UK tax when you live in Dubai.

Working it out, in order

For a corridor client the calculation is short once the order is right.

• Fix your residence first. Decide, under the Statutory Residence Test, whether you were UK resident for the year HMRC will assess. This decides which measure applies.
• Take only property and self-employment income. Ignore dividends, interest, employment and pensions, foreign or domestic, because they are not qualifying income.
• Apply the residence measure. If UK resident, include worldwide property and self-employment, so foreign rent counts. If non-resident, include only UK-taxable income, so foreign rent does not.
• Test the gross total against the threshold for the year, £50,000 from April 2026, then £30,000 and £20,000, and check the SA109 deferral if you are non-resident.

The threshold is not worldwide, and it is not domestic. It is whatever your residence makes it, and residence is a test you sit, not a place you keep a home.

Frequently asked questions

Does foreign income count towards the £50,000 Making Tax Digital threshold?

It depends on your UK residence status. If you were UK resident, your qualifying income includes worldwide property and self-employment income, so foreign rent counts. If you were not UK resident, only income declared on your UK Self Assessment return counts, so foreign property and foreign self-employment that are not on the UK return do not. Residence is decided by the Statutory Residence Test, not by where the property is.

Does my UAE or overseas rental income count if I live in the UK?

Yes. A UK resident's qualifying income includes worldwide property income, so rent from a property in the UAE, France or anywhere else counts towards the £50,000 threshold alongside your UK rent. It can be the income that takes you over the line into Making Tax Digital even where your UK income alone would keep you under it.

I live abroad and rent out UK property, does my foreign income count?

No, not if it is not on your UK return. As a non-resident, only your UK-taxable income counts towards qualifying income: your UK property income and any UK-land-dealing trade. A large overseas portfolio does not enter the calculation. A UAE-resident landlord with a big UAE portfolio and one UK let counts only the UK let towards the threshold.

What types of income count towards qualifying income?

Only income from self-employment and property, measured gross before expenses. Employment income, a share of partnership profit, dividends including from your own company, State Pension, private pensions, and income from REITs or property authorised investment funds are all excluded. Because the test looks only at trading and property income, most other income is irrelevant to the threshold whether it is UK or foreign.

Do foreign dividends, interest or a foreign salary count?

No. Dividends, interest, employment income and pensions are not qualifying income, whether they arise in the UK or abroad, because qualifying income is limited to self-employment and property. A person with large foreign dividend or interest income but modest property and trading income is not pushed into Making Tax Digital by the investment income.

How does my residence status affect the threshold?

Residence decides the measure. A UK resident is assessed on worldwide property and self-employment income; a non-resident is assessed only on income declared on the UK return. So the same overseas rent is inside the calculation for a UK resident and outside it for a non-resident. Getting the residence position right under the Statutory Residence Test is therefore the first step, because it fixes which income counts.

Which year's residence decides my qualifying income?

HMRC assesses the threshold from the Self Assessment return for the year it uses, and residence is decided separately for each tax year. A person moving between the UK and the UAE can be on the worldwide measure in a year they were UK resident and on the UK-only measure in a later year they were not. The year of departure, with split-year treatment and the SA109 page, is where the measure changes and is the most common point of error.

I have UK rental and overseas property, how do I work out my threshold?

Start with your residence for the relevant year. If you were UK resident, add your UK and overseas gross property income and any self-employment turnover, and test the total against the threshold. If you were non-resident, count only your UK property income and UK-declared self-employment, and ignore the overseas property. In both cases exclude dividends, interest, employment and pensions, and if you are non-resident check whether the SA109 deferral applies.
