We retired to Frnce about 4 years ago.I have investments in various countries which are paid into a UK bank account, but are not taxed in the UK. All income is declared in France and any due taxes are paid. I have filled on all the necessary double taxation paperwork, stamped and signed my my local tax office and returned to HMRC. My problem is that I have one UK based investment and I'am currently cashing in a UK based private pension. For reasons I don't understand both of these will be/are taxed in the UK at source and I have to fill in a self assessment form to claim back the tax. Does anyone else have a similar problem. Also will I recover all the tax or will it follow the personal allowance, 20%/40% procedure . Then is for any advice.
