Other ways to register

If you’re unable to register online, you can write a letter to HMRC instead.

You’ll need to create a 10-digit dummy Unique Taxpayer Reference (UTR) and should include this at the top of your letter.

To create a dummy UTR, use the year and month of the date you are sending your letter followed by six 5s — YYMM555555. For example, if you are sending your letter in July 2024, the dummy UTR would be 2407555555.

You will also need to include all the information from the ‘What you’ll need’ section in your letter.

Send your letter to:

Corporation Tax Services
HM Revenue and Customs
BX9 1AX
United Kingdom

After you’ve registered

The dummy UTR should only be used to chase the progress of your registration.

HMRC will process your registration and send your Corporation Tax UTR by post.
