By cheque through the post
You can send a cheque by post to HM Revenue and Customs (HMRC).
You do not need to include a street name, city name or PO box with this address.
Allow 3 working days for your payment to reach HMRC.
What to include
Make your cheque payable to ‘HM Revenue and Customs only’ followed by your Unique Taxpayer Reference (UTR) number. You’ll find this on your paying-in slip.
Include the paying-in slip HMRC sent you (if you still get paper statements). Do not fold the paying-in slip or cheque or fasten them together.
If you do not have a paying-in slip
You can print a slip to use to pay by post. You cannot use this at a bank.
