Set up a Direct Debit through your HM Revenue and Customs (HMRC) online account to make single payments for 31 January.
Set up another debit before 31 July if you need to make a payment on account.
You'll need to set up single payments each time you want to pay by Direct Debit.
You'll need to use your 11-character payment reference. This is your 10-digit Unique Taxpayer Reference (UTR) followed by the letter 'K'.
You'll find it either on your:
- HMRC online account
- paying-in slip, if you get paper statements
Your payment may be delayed if you use the wrong reference number.
Allow 5 working days to process a Direct Debit the first time you set one up. It should take 3 working days the next time if you're using the same bank details.
