I have no option but to send my SA200 by post as I don't have a computer. In previous years I have always been told to return the SA200 to BX9 1AS. The notes with the form this year say return to BX9 1LZ. However, the address shown on the top of the SA 200 is still BX9 1AS. HMRC can you tell me why the accompanying notes are telling me to send it to a different address to previous years.
