If you live and pay tax in the UK you must declare rental income from overseas property lettings on the foreign pages of your tax return. If you pay foreign tax on the income, you can usually get credit for this against the UK tax you have to pay on it.
You have to declare any income you get from overseas property lettings on the supplementary foreign pages of the Self Assessment tax return.
How much tax you'll pay depends on whether you're 'resident' in the UK and 'ordinarily resident' or 'domiciled':
You can be more than one of these - or none.
You will have to pay tax on the income from the letting whether or not that income is brought into the UK. This is known as the 'arising basis' of assessment.
As with income from a UK rental business, you normally work out the 'net profit' (or loss) for all your overseas property lettings as if it's a single business. To do this, you:
To arrive at your taxable profit, you can deduct certain allowances from your net profit. Your final profit counts as part of your overall taxable income, and you pay tax on it at your normal rates.
You can deduct the same expenses and allowances from overseas property letting income as from UK property letting income, including travel costs. (The expenses must be solely for running your property letting business.)
Because all overseas property lettings are treated as a single business, losses from one overseas property are automatically offset against profits from the others. And if you make a loss overall, you can offset it against future years' overseas rental profits.
But UK and overseas letting businesses are taxed separately - losses from one can't be offset against the profits from the other.
In this case you can claim to be taxed only on the income received in the UK in the year. This is known as the 'remittance basis'. (This does not apply if the property is in the Republic of Ireland.)
If you've already paid tax on your rental income abroad you can usually claim credit against the UK tax you'll have to pay on it.
Or you can deduct the foreign tax from your overseas rental income when you work out the profit you'll pay UK tax on.
Recording information on your tax return
If you’re claiming foreign tax credit relief, you’ll need to show separately:
If you’re not claiming relief for foreign tax, add together all your income and expenses for your overseas property letting and show the profit or loss as a single figure.
When you work out your taxable income, you have to convert it into pounds sterling. You use the exchange rate that applied when the rent was due (or when you brought it into the UK if you're not living in the UK permanently).
If you dispose of (eg sell or give away) your property you may have to pay foreign tax. You may also have to pay UK Capital Gains Tax (CGT). Where CGT is due you can usually get credit for foreign tax you've paid on the same gain.
You'll be liable to CGT whether or not you bring the gains into the UK.
You may only be liable on gains you receive in the UK (whether the gains were made in the current year or an earlier year).
