I am an Irish Tax resident and have a UK investment property, I have to declare my 2005 Irish Tax 31st Oct but don't have to report my UK tax until 31st Jan next, should I be seeking a tax credit in Ireland against my UK tax or the other way round, all suggestions welcome.
If you have a UK liability you will have to account for that and take a credit for taxes "paid" when submitting your Irish form. (you should have paid preliminary tax in the UK by this stage if you have a liability there)
You may not even have a UK liability but have an Irish liability on the income.
Get someone to look at the UK for you. Available if needed.
Under the relevant Double Taxation Agreement the UK has taxing rights on a UK situate property, therefore, you will be seeking a credit for UK tax paid against your Irish liability. Please note the UK tax year is still April to April not a calender year - like in Ireland
