Hi,
Please refer to the SA105 and SA106 help notes.
UK Property Notes
Foreign notes (2023-24)
If you receive income from FHL in the European Economic Area (EEA) you must complete the SA105 UK property pages. If you want to claim Foreign Tax Credit Relief on any foreign tax paid on your EEA FHL fill in the section ‘Foreign tax paid on employment, self-employment and other income’ on page F6 of the Foreign pages.
More information about FHL can be found in our HS253 on GOV.UK and Property Income Manual PIM4100. If you have a more specific query to your own circumstances then please expand further.
Thank you.
