Nearly 5.7 million taxpayers are yet to file their self-assessment tax returns, with less than a month left before the deadline on 31 January.

HMRC is urging customers to submit their returns as soon as possible to avoid missing the deadline and facing an automatic £100 penalty.

Last year, HMRC gave taxpayers extra time to complete and pay their 2020/21 tax return, waiving penalties for anyone submitting before 28 February 2022. However, customers should not expect extra time this year.

Over 12 million self-assessment customers are expected to file a return for the 2021/22 tax year, 42,500 of which chose to submit between 31 December 2022 and 1 January 2023. More than 25,000 online tax returns were filed on New Year's Eve, while 17,571 were filed on New Year's Day.

There are options available for customers with reasonable excuses for paying late and those unable to pay their tax bill in full, so long as they inform HMRC before the deadline.

HMRC's director general for customer services, Myrtle Lloyd, said:

"There is less than one month for customers to submit their tax returns and my message to those yet to start is: don't delay, do it online."
