Taxation due after moving UK

Can someone clear up this for me.

My uncle recently moved to Ireland from the UK. House was sold in UK and money is sitting in a bank account in UK, earning interest. Unlce receives a UK pension, works out about €130 p/w. He will start to work part time in Ireland over the coming weeks, earning about €250 per week.

I understand that tax has to be paid on the total of his weekly wage and pension (total €380 p/w), less tax credits.

What I looking into is the interest earned from the UK bank. 20 % dirt is paid in the uk. Is this his total liability or does this interest have to be taxed again like an added income in this country.

He should return interest earned and tax deducted thereon when making his annual tax return Form 12. Credit is given for UK tax deducted

If he is non-domiciled, he may have liability on UK income limited to amounts remitted to Ireland.

He should seek Tax advice to confirm his status and tax liabilities.
