HMRC bans credit card payments. HM Revenue & Customs is to stop accepting credit card payments less than three weeks before the 31 January 2018 deadline for submitting, and paying, self-assessment tax returns. The agency has charged about £12 million a year in commission to process credit card payments. An EU Directive being introduced on 13 January 2018 will prohibit all entities, including HMRC, from charging customers a fee for using MasterCard and Visa credit cards. The HMRC ban will go into effect that same day.
