Capital gains tax relief. Taxes paid in Spain

I have applied for the foreign tax relief, and at the end of the self-assessment, I don't receive any credit. I paid about £400 tax in Spain for selling a property there.

Hi

As we don't know what entries you made in the foreign pages of your tax return, we are unable to advise why your attempt to claim Foreign Tax Credit Relief was unsuccessful.
Please call HMRC and ask to speak to a taxes technician, who should be able to resolve the problem. Contact details can be found here
