You should contact Revenue now to see by what method they can pay you. You should have the P50 filled out and ready to go and your friend can post it in for you. You can fill that in now and perhaps just ask the friend to fill in the figures when you get them. If Revenue can only pay you back by cheque, then someone will have to pick that up from your address and send it along to you unfort. I've no idea if Revenue give refunds other than by cheque - hard to imagine that they don't as there are bound to be a lot of people working in Ireland and then travelling back to their home country mid-tax year. Revenue won't talk to someone else on your behalf unless they are a registered tax advisor as far as I know, but you should be able to do it all by post and have it ready to send off to them before you leave the country.
