I just chased my rebate I submitted in February! The cheque was sent out yesterday for a total of £771.60, which is higher than I expected. But still, near on 8 months turn around? Anyone else had problems like this?
Well, you "think" you overpaid to much would usually be the case for many people.
Sending your P60 in is the best thing to do. If you just send in a letter asking for a rebate you may get a letter back with an additional form asking for proof of earnings for the tax year - hence dragging out the ordeal even more.
