Online self assessment user id

I'm a numpty, I do this every blooming year, and yup this year is no different


I have forgotten my user id..... AGAIN!!

For some reason I thought it was my tax reference number....but apparently not (either that or I've forgotten my password too hahaha)

Can anyone refresh my memory as to the layout of the user id
- letters and numbers
- All numbers with spaces/without spaces
- All letters with or without spaces

I'm hoping it will jog my memory :panic:

Mine is my government gateway login (although if you have more than one government gateway login it will be the first one you used for tax) Gateway numbers are formatted in 3 lots of 4 digits eg 1234 5678 7654.

Mine is 12 numbers in a row. No spaces. Hope this helps.

Thanks ladies, I managed to find my details, nothing was what I thought it was haha
All done and dusted now though, well, till next years lol
