Unique Tax Reference Number
This is issued by HMRC when you register for self-assessment tax returns. You can only have one UTR number and it is important that you keep a record of this for reference.
If you can’t find your number or believe you have not had one issued after registration for self assessment, then you can contact HMRC to have it reissued out to you.
Your personal tax return can’t be submitted without your UTR Number. The deadline for the submission is 31/01/2017.
