I was slightly bothered after moving to Spain from the UK because I had to submit the IRPF and similar. You never have to think of such a thing in the UK unless you see the wrong code on your payslip, and that is always in order to get a refund. People of the US won't trust a damn thing the government does, probably for pretty good reason, and the whole country suffers for it. IRS can adequately track and report your taxes, even refunding them if they're too high? HELL NO, gotta blow most of that potential refund on a tax adviser to prove that I could get refunded! HMRC can adequately track and report your taxes? Actually, most of the time yes. No need to file unless it's a more complicated setup.
