Income from Spanish Villa Tax already paid but how to deal with it tax return and not be taxed

So we have have a villa in Spain where we have paid 24% tax on gross income from holiday letting. On my tax return if I add the income in the EEA property section and then foreign tax credit, this still calculates that i pay income tax on the balance. eg, so say the income was £1000 and tax paid in Spain was 240. on my calculation in my draft UK tax return, the balance ie 760 is then taxed at 20%, so double taxation, That cannot be right. Help please. Where in my tax return do i deal with this, so i don't pay any UK income tax as there is a double taxation agreement? so that while there was an income of £1000, all tax paid, so not added for purpose of calculating income tax due. Or do i have to reclaim that tax paid separately and if so how do i do that? thank you

Hi Rob Graham,
You need to declare the £1000 as income and then claim the £240 as foreign tax credit relief.
If the UK tax is less it will be limited to what that is.
Thank you.
