Around 5,542,000 taxpayers have less than a month to complete their Self Assessment tax returns before the 31 January deadline.
In total, more than 11.5 million 2017/18 tax returns are due and HM Revenue and Customs (HMRC) expects the vast majority of taxpayers to complete their returns and pay any tax owed by the end of the month.
Approximately 52% of taxpayers have already filed their returns, as of 31 December 2018, and more than 5 million have completed their returns online (88% of the total returns filed).
Financial Secretary to the Treasury, Mel Stride, said: “It is encouraging that around 52% of taxpayers have already completed their Self Assessment tax returns. With less than one month to go before the deadline, there are still many people that need to act now.
“HMRC is encouraging all Self Assessment filers to complete their returns by 31 January and is offering support every step of the way.”
