How to find your Government Gateway User ID
Most people use their Government Gateway Gateway ID to deal with their tax affairs online. When you first set up your account with the Government Gateway, your user ID would have been sent to you, either by post or by email. It would have been a long string of up to 12 numbers.
You could look through your email inbox, and search using the subject heading "Government Gateway user ID". If you can't find the email, you could telephone the appropriate HMRC helpline telephone number.
