From 13 January 2018, HMRC will no longer be accepting payments from personal credit cards to pay tax liabilities. This will include payments for personal tax liabilities, VAT, and PAYE.
That means that if you are planning on settling your personal tax liability that is due by 31 January 2018 and was planning on using a credit card, you will need to make payment before 13 January 2018. If you are self-employed, you should assess your finances now to consider how you are going to pay any tax liability that is due by 31 January 2018.
The rule changes have come in due to EU restrictions which prohibits merchant fees being recharged to payers. HMRC cannot currently take payments at a cost to the public finances, so this will mean they are no longer able to accept credit card payments.
