Capital Gains Tax on Portuguese house sale

[taxationconfusion]

Hi.
I was born and have lived my whole life in England. I inherited a share of a relative's house in Portugal several years ago and it sold in August 2024. I have paid capital gains tax in Portugal. Do I need to declare the gain and pay tax in the UK as well or does the double tax treaty mean tax is only due in Portugal?
Thanks for any help.

If you're tax resident in the UK it'll be taxable here too, albeit you should get a foreign tax credit for the Portuguese tax paid.

Just be aware the rules on expenses and cost basis may be different to Portugal (along with exchange rate considerations at spot rates), so the gain may be different, but HMRC do accept that you don't need to apportion the FTC available. So tax should only be due if the UK tax rate is higher.
