It's hell in the UK if your tax affairs are more than simple. I have three incomes, two with benefits and own a limited company. Tax return is hell as I'm on PAYE with two companies (yes this is legal). Usually end up owing HMRC a grand or two and have to spend 5 days a year working it all out (I won't hire an accountant as they're shysters and I've been screwed by two so far - bring on RDR).
