Oddly enough, I am in the unfortunate position at one level but fortunate in another that about five years ago, if not longer, I got my last letter from the Inland Revenue. It said, "Please do not send us any more tax returns because we know what your income is. It has been the same for the last 10 years so don't bother any more". If I moved house, I am not sure that anyone would know where I had gone. I assume that you have to tell the Inland Revenue but the fact is that there is this problem. As far as I am aware, PAYE is paid on the basis of where you are employed, who employs you and the income that you are paid. That can come from a variety of sources and is taxed at source. I am never quite clear whether one's residence is an important part of that issue.
