Almost 340,000 people have used it to pay since 6 April 2025, an increase of 132,788 people compared to the same period last year.

Self Assessment customers need to file their tax return online for the 2024 to 2025 tax year and pay any tax owed by 31 January 2026.

HMRC is encouraging those yet to start theirs, to go to GOV.UK and do it now. Anyone who misses the deadline could be subject to an automatic £100 penalty.

Filing tax returns ahead of the deadline means knowing how much tax to pay sooner. It is quick and easy to pay via the HMRC app and set up payment reminders to make sure the deadline isn’t missed.

Myrtle Lloyd, HMRC’s chief customer officer, said: “The Self Assessment deadline is less than one month away, and thousands of people have already paid their tax bill via the HMRC app.

“It is quick and easy to do, and you can also see your payment history.

“Search ‘download the HMRC app’ on GOV.UK to access the app and make your Self Assessment payment.”

People unable to pay any tax owed in full may be able to set up a Time To Pay arrangement, if they meet the eligibility criteria and they owe less than £30,000.

Alternative options include paying directly through a bank account, direct debit or paying online via GOV.UK. A full list of payment options can be found on GOV.UK.
