By debit or corporate credit card online

You can pay online.

There’s a fee if you pay by corporate credit card. The fee is not refundable.

You cannot pay by personal credit card.

Use your 10-digit Unique Taxpayer Reference (UTR) followed by the letter ‘K’ as your payment reference. You’ll find it either:

HMRC will accept your payment on the date you make it, not the date it reaches their account - including on bank holidays and weekends.

If you’re unable to pay your Self Assessment tax bill in full by card, you should use another payment method like a bank transfer.
