Only working 1 month in 2010 tax year.. refund?

Hi, I will finish up employment with my Irish based employer on Jan 22nd and will be relocating to the UK to take up full time (i.e. will be domiciled in the UK) position in London. My question is can I claim my full years Irish PAYE tax free allowance from my January pay check on the provision I will not have any other Irish income in this tax year? Should my employer organise this at source or do I have to make a seperate request directly to the revenue for a refund?

Any advice greatly appreciated.

You can take advantage of the split year basis of assessment, so you will get a full year's tax credits in both countries.

So you will pay no tax in Ireland.

Your employer should operate tax as normal, and you will claim a refund.

If the amount of the refund was not large, the employer might adjust the tax credits to give you two months' credits and lower rate bands. In theory this is wrong, but in practice it saves a lot of admin and I doubt if the Revenue would have any problem with it.

Thank you Brendan.. thats exactly what I was looking for
