Hi
You can only claim the expenses that are set against the property in the country the property is in.
The profits of the overseas property business are computed in the same as the profits or loss of a trade, just like a UK rental business.
This means that a UK resident landlord will pay tax on the same profits both here and abroad. But the double charge is relieved by deducting the overseas tax paid on the property income from the UK tax due on the same income. (
PIM4702 - Rent from property outside the UK: Income Tax (IT)).
Thank you
