I got home today to find an HMRC envelope, tatty looking paper inside and the instructions to fill it in (my name, hubby's name and address) and post it back (not even a pre-paid envelope).
Being the suspicious person I am alarm bells were sounding when it states it's a TC664 (change of circumstances) form yet the instructions tell me to go online and find out how to complete a TC600 form - which looks nothing like this.
