The countdown is now on to submit your tax return before the 11:59pm deadline tonight (31 January 2019).

According to HMRC, 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.”

Self Assessment customers can submit their return via their personal tax account, it takes five minutes to sign up for an account. If you think you will not be able to submit your tax return by 31 January, please let HMRC know so they can help you.
