clientservices@lsrpartners.comMany non-residents assume that after enough time outside the UK, capital gains tax on UK property disappears. It does not.
The answer is no.
Capital gains tax on UK property applies to non-residents with no time limit. There is no point at which the liability disappears because you have been gone long enough. But there are important reliefs available depending on when you bought the property, and a significant trap for anyone who returns to the UK within five years of leaving.
Here is what you need to know before you sell.
Non-resident capital gains tax, known as NRCGT, came into force in April 2015. Before that date, non-residents were not subject to UK capital gains tax on UK residential property disposals at all.
That historical starting point matters because it directly affects how the gain is calculated for properties purchased before April 2015. HMRC does not automatically tax the entire gain from the original purchase date. Instead, specific relief options are available that can significantly reduce the taxable amount.
From April 2015 onwards, any gain on the disposal of UK residential property is subject to capital gains tax regardless of your residence status. Selling UK property as a non-resident does not remove the obligation. Neither does the length of time you have been outside the UK.
Non-residents who sell UK residential property must report the disposal to HMRC within 60 days of completion and pay any capital gains tax due at the same time. This applies even where reliefs reduce the taxable gain to nil or close to it. Missing the 60 day deadline triggers automatic penalties.
If you owned UK property before April 2015, two relief options are available. You can choose whichever produces the more favourable outcome for your specific circumstances.
Rebasing allows you to treat the market value of the property as at April 2015 as your base cost rather than the original purchase price. Only the gain arising from April 2015 onwards falls within the scope of NRCGT.
For properties that have been owned for a long time and appreciated significantly before 2015, rebasing often produces the most favourable outcome. The pre-2015 growth falls entirely outside the scope of UK capital gains tax.
Time apportionment relief takes a different approach. It calculates the total gain across the entire period of ownership and apportions the taxable element to the period from April 2015 onwards.
Take a property owned for 30 years, 20 of which fell before April 2015. Under time apportionment, only 10 thirtieths of the total gain would fall within the scope of NRCGT. The pre-2015 portion falls outside it.
For some ownership profiles this produces a better result than rebasing. The right choice depends on how the property has appreciated over time and when the most significant growth occurred.
A third option also exists. You can calculate the gain as if you had always been UK tax resident and taxable on the full amount from the original purchase date. This rarely produces the best result but can occasionally be useful in specific circumstances, for example where the property has made a loss or where other reliefs interact in a particular way.
The rate of capital gains tax you pay on UK residential property as a non-resident depends on your UK income position for the year. Gains that fall within the unused basic rate band are taxed at 18%. Gains above that threshold are taxed at 24%.
For non-residents with limited UK income, a meaningful portion of the gain may fall within the basic rate band, which makes the rate calculation worth working through carefully rather than assuming the higher rate applies to everything.
This is the part of the rules that catches people out most often, particularly those who leave the UK intending to stay away but return sooner than planned.
If you leave the UK and return within five years, HMRC treats you as temporarily non-resident. Any gains that were not fully taxed during your period of non-residence can be brought back within the scope of UK capital gains tax in the year you return.
Most people understand this principle in relation to investment portfolios. Leave the UK, sell a large holding of shares, crystallise a significant gain outside the UK capital gains tax net, then return within five years and those gains come back into charge.
What fewer people realise is that the same logic applies to UK property gains under the NRCGT rules.
If you sold a UK property during your period of non-residence and benefited from the pre-2015 reliefs, meaning you were taxed on less of the gain than you would have been as a UK resident, the portion that was not fully taxed can be brought back within scope if you return to the UK within five years.
This is not a theoretical risk. It arises for clients who planned a long-term move overseas, sold UK property during that period at a reduced capital gains tax rate, and then returned to the UK earlier than expected for personal or family reasons.
The temporary non-residence rules treat the under-taxed element of the gain as if it arose in the year of return. The tax consequences can be significant, particularly if the gain was large and the relief obtained during the period of non-residence was substantial.
The interaction between NRCGT, the pre-2015 reliefs and the temporary non-residence rules means that the tax consequences of selling UK property as a non-resident depend heavily on your specific circumstances.
When did you buy the property? How long have you been non-resident? Are you planning to return to the UK and if so when? All of these factors affect both the amount of tax you pay and whether the temporary non-residence rules could apply to bring additional gains into charge later.
Getting the calculation right before you sell is considerably easier than trying to correct an incorrect position after completion. And understanding the implications of any plans to return to the UK before you make irreversible decisions is essential.
