UK Resident with Rental Income in Ireland

Hi I would like to ask if I will need to pay tax in the UK if I already pay tax for my rental income in the Republic of Ireland? And if so how do I do that? And how do I declare my Ireland rental income to the HMRC? Thank you.

Hi,
If you do not already complete Self Assessment returns, then you should register for Self Assessment to report your foreign income. To register, please visit:
Check how to register for Self Assessment
When you complete your Self Assessment return, you will be able to include details of any foreign tax already paid on your foreign rental income, and claim Foreign Tax Credit Relief to avoid double taxation. Foreign Tax Credit Relief is always limited to the amount of UK tax that would be due on the foreign income. You can see general information about tax on foreign income here:

Thank you.
