Girobank reports that 2500 people used its Internet bill payment service last month to meet the 31 January self assessment tax deadline, paying a total of £3.3 million online.
On 31 January alone, 700 taxpayers used the BillPay service to pay almost £1.3 million in tax.
The Inland Revenue is one of 145 organisations that accept payments via Girobank's BillPay portal. Users do not need an online bank account - just a debit card, such as Switch, Delta, Solo or Electron. The service uses secure, 128-bit encryption technology.
Graham Baughan, BillPay product manager, says: "No-one likes to pay tax but, with BillPay, we have tried to make the process as easy and painless as possible."
Other electronic payment methods offered by the Inland Revenue include direct credit by Bacs or Chaps, telephone and Internet banking and debit card over the telephone.
