Foreign property is where MTD gets genuinely difficult. The rules are not far off UK property, but most software and guidance assume all your property is here.
Add a Barcelona apartment, a villa in the Algarve or a studio in Dubai and the standard workflow breaks: it has to be filed separately from your UK property, every euro or dollar converted into pounds, and your true UK tax bill cannot be settled until the relief for tax paid abroad is applied at the year end.
First, a point that catches people out. A UK resident who lets property abroad is not a non-resident landlord. The Non-Resident Landlord Scheme is for people who live overseas and let property here, so it does not apply to you.
I deal with this every day. A large proportion of our clients own property abroad and building RentalBux to handle foreign property was one of our earliest decisions. This guide is what I would tell a landlord sitting across my desk with an overseas portfolio and a list of MTD questions.
This guide assumes you already know how quarterly updates, the Final Declaration and the qualifying income threshold work. If not, start with our complete MTD for Income Tax guide, then come back for the foreign property layer.
KEY TAKEAWAYS
Your overseas lettings form one foreign property business for MTD, separate from UK property, however many countries are involved.
Gross foreign rents count towards the qualifying income threshold, aggregated with UK rents and any self-employment turnover.
Every figure you file must be in sterling. You convert each transaction and keep both the foreign currency and the sterling amount in your records.
Double tax relief is claimed at the Final Declaration and worked out per country, so you must track income and foreign tax by country from the first quarter.
The finance cost restriction known as Section 24 applies to overseas residential property exactly as it does to UK residential property.
Most mainstream cloud platforms do not support foreign property filing. Check the specific income types your software is recognised for, not just whether it is MTD ready.
Is Your Foreign Property a Qualifying Business for MTD?
Under MTD, all your overseas rental properties are treated as one qualifying business, separate from any UK property you hold.
A UK resident landlord who owns both files two sets of quarterly updates: one for the UK property business, covering every UK property combined, and one for the foreign property business, covering every overseas property combined, regardless of how many countries are involved.
Key Fact
A landlord with a Spanish apartment, a French villa and a US condo files one combined foreign property quarterly update, not three updates by country. All foreign rental income and expenses are aggregated into a single business for MTD. This mirrors the Self Assessment position, where foreign property income is reported on the SA106 foreign pages as one property business.
The UK and foreign updates are filed separately, through different HMRC endpoints. For the qualifying income threshold test, though, they are added together, along with any self-employment turnover.
So the threshold test combines everything, while the quarterly reporting keeps the two property businesses apart. Hold on to that distinction, because it catches people out in both directions.
How Foreign Rents Count Towards the Qualifying Income Threshold
Your gross foreign rental income counts towards the qualifying income threshold. It is aggregated with your UK gross rents and any self-employment turnover.
Worked Example
James runs a consulting business with £60,000 of gross turnover, owns three UK buy to lets producing £42,000 of combined rent, and lets a Barcelona apartment to tourists for £18,000 a year.
His aggregate qualifying income is £120,000, well above the threshold. Once mandated, he files three quarterly updates each quarter: self-employment, UK property and foreign property. That is twelve quarterly filings a year, plus one Final Declaration.
Foreign property is mandated on the same timetable as everything else: MTD applies from 6th April 2026, when your combined qualifying income is over £50,000, from 6th April 2027, when it is over £30,000, and over £20,000 from 6th April 2028. The first wave is already in effect.
You can confirm your own position with HMRC's eligibility guidance. The point to take from this section is this: Overseas rent is not separate from the threshold but a part of it.
Are Your Foreign Rents Taxable in the UK Yet?
The UK taxes its residents on worldwide income, so foreign rental profit is normally taxable here whether or not you bring the money home.
Once Exception
Since 6th April 2025 the remittance basis has been replaced by the four-year foreign income and gains regime. A qualifying new arrival who has not been UK resident in the previous ten years may claim to have their foreign income, including overseas rental profit, exempted from UK tax for their first four years of UK residence.
If you fall within that regime, your reporting position is different, and you should take advice before assuming the standard rules apply to you. For everyone else, your foreign rents are taxable in the UK, and the rest of this guide is what you need.
How MTD For Foreign Property Owners Look Like
Converting Foreign Income and Expenses to Sterling
Every figure you file with HMRC must be in sterling, converted using one method that you apply consistently to every foreign property for the whole year.
HMRC accepts three approaches.
Transaction date rate: The exchange rate on the date of each individual transaction. This is the most accurate method and the most time-consuming, because it needs a spot rate for every rent receipt and every payment.
Period average rate: HMRC publishes monthly average exchange rates on GOV.UK. Using the monthly or quarterly average for all transactions in that period is an accepted simplification.
Actual conversion rate: Where you actually convert currency at a point in time, the rate your bank or currency service gave you can be used.
Whichever method you choose must be applied consistently across all your foreign properties for the year. Switching between methods or between properties to pick up a more favourable rate is not allowed. Choose a method, write it down and stick to it.
What I Recommend
For most clients I recommend HMRC's published monthly average exchange rates. They sit on GOV.UK, they are easy to defend in an enquiry because HMRC published them, and they remove the need to look up a spot rate for every line.
HMRC's own approach to exchange rates for tax purposes is set out in its Business Income Manual at BIM39515. Traders have flexibility in choosing exchange rates. They may use rates quoted by their bank, London closing rates, or the monthly average rates published by HMRC for VAT purposes, provided the chosen method is in accordance with generally accepted accounting practice (GAAP). That gives a sensible balance between accuracy and effort.
Convert before you file, not after. Your digital records should store the sterling figure alongside the original foreign currency amount. The quarterly update reports only the sterling, so HMRC never sees the euro or dollar figures.
If you use a feed from a foreign bank, check whether your software converts automatically at a rate you can set, or whether it imports the foreign currency and leaves you to convert by hand. Across four quarters, that difference in workflow is significant.
Tracking Each Property by Country
Track every foreign property by country from the first quarter, because HMRC identifies each property by a country code and your year end double tax relief is calculated country by country. HMRC's foreign property design includes a unique property identifier for each overseas property, linked to a country code.
When your software submits a foreign property for the first time, it sends the property name and country code and receives an identifier in return. This identifier is then used in every later submission for that property.
This is a real difference from UK property, where individual properties are not separately identified in the submission. For foreign property, HMRC wants to know which property, in which country, the income relates to.
Not every part of this is fully enforced yet, but it is expected to become mandatory, so set each property up with its country code from the start.
Even if HMRC did not require it, there are strong reasons to track income and expenses by country inside your software:
Double tax relief. This is the credit that stops the same rental profit being taxed in both the country where the property sits and the UK. It is calculated country by country, so without per-country figures, the year-end relief claim becomes very hard to do accurately.
Different cost profiles. Management fees, local property taxes and compliance costs vary by jurisdiction. Per country tracking shows you which properties, in which countries, are actually making money.
Local tax returns. Many countries require you to file a local return on the rent. The data the Spanish return needs differs from what the French return needs. Per country records serve both.
Currency. Different countries mean different currencies and rates. Per country tracking makes sure the right rate is applied to each.
Tip: Set your software up to track by country and by individual property from day one. Reconstructing per country and per property splits from a combined record at year end, especially for the double tax relief calculation, is one of the most time consuming jobs in property tax. Getting the structure right at the start costs nothing. Fixing it later costs hours. |
Filing Your Quarterly Updates for Foreign Property
The foreign property update follows the same rhythm as everything else under MTD: cumulative year to date totals, filed by the same deadlines of 7 August, 7 November, 7 February and 7 May. The mechanics are identical to your UK property update. Four things are different.
Everything is in sterling. The converted amounts, not the original currency, are what sit in your digital records and your update. HMRC does not accept euros, dollars or any other currency.
Fewer expense categories. HMRC uses a simpler category structure for foreign property than for UK property, which reduces the categorisation work each quarter.
Section 24 applies to overseas residential property. Finance costs on overseas residential property are subject to the same basic rate credit restriction as UK residential property, known as Section 24 after section 24 of the Finance (No. 2) Act 2015. They go in the residential property finance costs category, not in general expenses. People assume this does not reach overseas property. It does.
Simpler categorisation is always available. For UK property, simpler categorisation is only available below the £90,000 VAT registration threshold. For foreign property it is available whatever the income. That means you can report just three figures a quarter: total income, total expenses excluding finance costs, and residential property finance costs. For an overseas portfolio, where mapping local costs to HMRC's UK focused categories would be awkward, this is a real saving.
What a quarterly update looks like: You let an apartment in Barcelona. For the quarter to 05/07 you receive rent of €4,500 and pay a management fee of €450, local property tax (IBI) of €300, insurance of €200 and mortgage interest of €600. Using HMRC's published average for the period, say €1.17 to £1: |
Category | EUR | GBP filed |
|---|---|---|
Total property income | €4,500 | £3,846 |
Total expenses (excluding finance costs) | €950 | £812 |
Residential property finance costs | €600 | £513 |
Only the sterling column goes to HMRC. The euro figures stay in your records, and your software should keep both for audit purposes.
Claiming Double Tax Relief at the Year End
Most UK residents with foreign property pay tax on the rent twice over: once in the country where the property sits, and again in the UK on the same profit. Double tax relief, given as foreign tax credit relief, stops that. It is claimed at the Final Declaration, never in the quarterly updates. HMRC's overview of relief where you are taxed in more than one country is at Tax on foreign income.
The mechanism is straightforward in principle. The UK taxes your worldwide income, including the foreign rental profit. You then claim a credit for the foreign tax you have already paid, capped at the amount of UK tax due on that same income.
If the foreign tax is lower than the UK tax on the income, you pay the difference here. If the foreign tax is higher than the UK tax, the excess cannot be refunded or used to reduce tax on other types of income. Furthermore, unlike certain corporate tax scenarios, individuals cannot carry forward this excess foreign tax to future tax years; it is effectively lost.
One practitioner point that is easy to miss: where the foreign tax exceeds the UK tax on the income, claiming the foreign tax as a deduction against the rental profit rather than as a credit can sometimes give a better result, because it can create or increase a loss to carry forward. It is worth comparing both before you file the Final Declaration. [FLAG - partner to confirm the deduction alternative for the client's facts]
The relief is worked out country by country. A landlord with property in Spain and the US calculates the Spanish relief separately from the US relief. This is why per country tracking is not optional: without it, the calculation cannot be done properly.
Warning
The in year tax estimate your software shows after each quarterly update does not account for double tax relief. For anyone who has paid foreign tax, that estimate overstates the UK liability, sometimes substantially. Treat it as a rough gross figure, not your real bill. The accurate position only appears at the Final Declaration once the relief is applied.
The Final Declaration for Foreign Property
The Final Declaration for a landlord with foreign property includes everything a UK only landlord declares, plus the foreign specific elements.
The cumulative quarterly data carries forward and the full year foreign result is confirmed. If you used simpler categorisation during the year, you do not have to provide the full category breakdown at year end for foreign property.
Your double tax relief claim goes in here, calculated per country, supported by evidence of the foreign tax paid, usually a foreign assessment or payment receipt. Foreign residential finance costs join any UK residential finance costs in the single Section 24 basic rate credit calculation, computed on the combined total.
And if exchange rates moved sharply during the year, the cumulative converted figures may need reviewing against the actual sterling equivalents, which matters most where a large one off cost, a major repair or a tax payment, was converted at a rate different from the monthly average you used through the year.
The deadline is 31 January after the tax year, with the same payment dates as any other MTD taxpayer. For how the Final Declaration works in general, see our [complete MTD for Income Tax guide].
What Your Software Must Handle for Foreign Property ?
This is the single biggest practical problem for landlords with overseas property, so it deserves a clear summary. HMRC uses entirely separate endpoints for foreign property: Foreign Property Income and Expenses Period Summary, Foreign Property Annual Submission and Foreign Property Details. Software that has only built the UK property endpoints cannot touch foreign property, whatever its marketing says about being MTD ready.
At the time of writing, several leading cloud platforms including FreeAgent and Sage support sole trader and UK property income but do not support foreign property filing under MTD. This is not a temporary gap waiting to be filled. Foreign property is a niche many general platforms have chosen not to prioritise.
Requirement | Why it matters |
|---|---|
Recognition for foreign property | UK property recognition alone is not enough. Without foreign recognition the software cannot submit your foreign updates. |
Separate foreign property endpoints | HMRC uses different endpoints for foreign income. The software must connect to these specifically. |
Per property identifier with country code | Each foreign property must be linked to a country. Your software must support this. |
Multi-currency recording | Foreign currency stored alongside its sterling conversion, with a configurable rate method. |
Per country tracking | Essential for the year end double tax relief calculation. |
Section 24 routing for foreign residential | Overseas residential finance costs must land in the correct restricted category. |
Simpler categorisation | Available for foreign property at any income level. The software should offer it. |
If your current platform does not meet these, you have three options: switch to one that does, run a second platform alongside your main one for foreign property only, or use bridging software to connect a spreadsheet to HMRC's foreign property endpoints. The third is technically valid but adds manual work and digital link risk. A second subscription for one income type is workable, but it means two sets of records and a reconciliation at year end.
Full disclosure: this is one of the reasons I built RentalBux with foreign property support from the outset. It holds recognition for UK property, foreign property and self-employment, which is an uncommon combination, and if you have mixed income including overseas property the software choice genuinely matters.
Practical Challenges Unique to Overseas Property
Foreign property creates workflow problems UK property simply does not have. These are worth planning for before the first deadline.
Source documents may arrive in the local language. Agent statements, local tax receipts and invoices often come in Spanish, French or Portuguese. You will need either a translation or enough familiarity with the document format to pull the right figures. Agreeing a standard reporting format with your overseas agent saves real time.
Local tax years rarely match the UK's. Many countries run a calendar tax year, while the UK year runs to 5 April. Income on the Spanish return for 2026 straddles two UK tax years. Allocate every transaction to the correct UK quarter, not to the local tax period. This one trips people up regularly.
Local compliance does not go away. You may need to file a local return, register with the local authority and keep records to local rules, all alongside UK MTD. Be clear about whether your UK adviser handles any of that or only the UK side.
Foreign bank feeds are patchy. Rent may land in a foreign account. If a feed is available it can be imported and converted; if not, you enter transactions by hand from the statements. Availability varies a great deal by country and bank.
For accountants: State in the engagement letter whether you are handling UK MTD quarterly updates and the Final Declaration only, or UK MTD plus the local country return. Most disputes I see arise from a client assuming that handling the property included the overseas filing. If you do not handle the local return, recommend a local adviser and put that recommendation in writing. Price the foreign element separately, because currency conversion, separate endpoints, per country relief and foreign language documents make it genuinely more work than a UK only portfolio.
Foreign Property Owned Jointly
Jointly owned overseas property follows the same principles as jointly owned UK property. Each co-owner files their own quarterly updates for their share, each is tested against the threshold individually, and the jointly let easement, which lets passive co-owners report only their share of income each quarter and defer the expense detail to the Final Declaration, applies in the same way.
Joint ownership, foreign property and currency conversion together create three layers at once. Each co-owner's share of each transaction has to be calculated, converted to sterling and reported in their own update. Where ownership ratios differ across properties in different countries, apply the per property split first, then aggregate by country, then convert. For a passive co-owner, the jointly let easement is especially valuable here, cutting the in year obligation to reporting a converted share of income each quarter. For the full mechanics, see our MTD for jointly owned property guide.
Common Mistakes With Foreign Property and MTD
"My software is MTD ready, so it handles foreign property." Recognition is per income type. UK property recognition does not cover foreign property. Check the specific income types your software is approved for.
"Foreign rent does not count towards the threshold." It does. Gross overseas rent is aggregated with UK property and self-employment income for the qualifying income test.
"I can report in euros." No. Every figure in an HMRC submission must be in sterling. Conversion is required for every transaction.
"I will sort the per country split at year end." By year end you need per country figures for double tax relief and potentially per property figures for HMRC's identifier system. Rebuilding that from a combined record is one of the most painful exercises in property tax.
"Section 24 does not apply abroad." It does. The finance cost restriction applies to all residential property held personally, wherever in the world it is.
"The quarterly estimate is my real bill." For anyone paying foreign tax, the estimate is overstated because it cannot include double tax relief. The accurate figure only appears at the Final Declaration.
"The local return is not my problem." Many countries require a local return on the rent. Confirm in writing whether your UK adviser handles it.

What to Do Next
Start by confirming whether your current software actually supports foreign property MTD filing. If it does not, do not wait until the first deadline to find out, because the switch takes time and your records need to be in the new system before the quarter closes.
Set each foreign property up with per country and per property tracking from day one, choose your exchange rate method and document it, and if you pay tax where the property is, start collecting the evidence early so the double tax relief claim is straightforward.
Foreign property is the part of MTD where good advice pays for itself.
