The easiest way to pay your self assessment tax bill is by transferring the money online from your bank using Faster Payments.
If you have a bill it will tell you which account to use. If you don’t have a bill, or you’re not sure, use HMRC Cumbernauld. Most banks have an option to choose Cumbernauld or Shipley. If not, the account details are shown below.
You’ll need to use your 11-character payment reference when you pay. This is your 10-digit UTR (Unique Tax Reference) followed by the letter ‘K’.
