When you set up your limited company, HMRC will post your Corporation Tax UTR to the company’s registered address. You may also receive a CT600 notice (a letter reminding you to file your company tax return) that includes the same code.
What the UTR is for
Your company UTR is a 10-digit number that identifies your business for Corporation Tax purposes.
We’ll need this code to file your company’s tax returns with HMRC.
Keep it confidential - it should only be shared with your accountant or HMRC.
You may also have a separate personal UTR for Self Assessment. Make sure not to confuse the two.
If you haven’t received it
You can request a copy of your company’s UTR from HMRC online. HMRC will post it to the business address registered with Companies House.
