When does self assessment tax have to be paid?

You’ll need to pay self assessment tax by the UK government deadline to avoid penalties and interest fees. If you file a late return up to 3 months after the deadline, the penalty is £100 plus accrued interest¹.

The penalty can increase for late payment, and for filing more than 3 months after the deadline. There’s a tool on the UK government website to calculate the late payment penalty you may need to pay². To avoid this, make sure you pay self assessment online or by post by the deadlines:

• 31st January for your balancing payment covering any tax owed from the previous year
• 31st January for the first payment on account
• 31st July for the second payment on account

Paying self assessment by Bacs

You can also choose to pay self assessment through CHAPS, Bacs and Faster Payments⁴. The process for all 3 payment types is the same, but check if your own bank charges different fees for these services as that may make one a more attractive option for you. Bacs payments can take 3 days to arrive, while CHAPS and Faster Payments should arrive on the same day.

Your self assessment tax bill will give you the bank account details you’ll need to pay into. If you do not have a bill, or you’re not sure, you can pay into either:

• Sort code - 08 32 10
• Account number - 12001039
• Account name - HMRC Cumbernauld

OR

• Sort code - 08 32 10
• Account number - 12001020
• Account name - HMRC Shipley

If you’re paying from an account which is overseas, you’ll have to pay into one of the following accounts:

• Bank Identifier Code (BIC) - BARCGB22
• Account number (IBAN) - GB62BARC20114770297690
• Account name - HMRC Cumbernauld

OR

• Bank Identifier Code (BIC) - BARCGB22
• Account number (IBAN) - GB03BARC20114783977692

Pay self assessment by debit card

You’ll be able to pay self assessment tax through debit or corporate card and it’ll be processed either on the same day or the following day depending on the time you initiate it⁵.

You’ll need to:

• Go to the UK Government and HMRC website.
• Click 'Start your Self Assessment payment'.
• Select 'pay by card'.
• Payments can only be made from corporate cards or personal debit cards - personal credit cards aren’t accepted.
• Bear in mind you need your UTR as a reference - use this 10 digit number, followed by K to generate your payment reference.

Paying self assessment by Direct Debit

If you want to pay self assessment tax through direct debit⁶ you can do so - but bear in mind it’ll take 5 working days to set up a new direct debit, or 3 days if you’ve previously used this payment method.

You can set up weekly or monthly direct debits as part of a budgeting plan, or you can make an annual payment if you’d prefer. You’ll need to find your UTR and use this, followed by the letter K as the reference you use when you create your direct debit with your bank or building society.

Pay self assessment by cheque through the post

Finally, you’ll have the option to pay self assessment tax through the post by sending a cheque⁷. Make your cheque payable to ‘HM Revenue and Customs only’.

The mailing address you need is:

Direct
BX5 5BD

You do not need to include a street name, city name or PO box with this address, and you’ll need to allow 3 working days for your payment to reach HMRC.
