From 13 January 2018 HMRC will no longer take payments for outstanding tax charges by personal credit card.
The HMRC notice reads:
The EU Payment Services Directive 2 comes into effect on 13 January 2018. This new legislation removes the ability for merchants including HM Revenue and Customs (HMRC) to charge back fees for payments made by personal debit and credit cards to the customer. However, as HMRC doesn’t make a surcharge for debit card payments, this change only impacts personal credit card payments.
As a public funded body, HMRC is unable to absorb the cost of personal credit card fees as this would ultimately mean charging the fees back to customers through the public purse. It has been agreed that HMRC is unable to accept personal credit card payments from 13 January 2018.
