Hello, I received a cheque from revenue today and I have a fair idea they have made a mistake in my favour, A few hundred euro in fact, Should I contact them and have them revise it or will they figure it out eventually, I know I should contact them but for once I just would like to come out the better, I am tax compliant in every way possible and I know I should sort this out but the greedy side of me is saying take it and run.
