The deadline of 31st January to file your 2021-22 Self-Assessment tax return is fast approaching. Last year over 12.5 million taxpayers were required to complete a Self-Assessment tax return but over 2.3 million taxpayers missed the 31 January deadline.

The deadline to submit your 2021-22 Self-Assessment tax return online is 31 January 2023. In addition, any tax due should also be paid by this date. As well as the first payment on account due for the current tax year 2022-23, it includes any balance of Self-Assessment liability for 2021-22.

A £100 fixed penalty will usually be charged if you miss the deadline, regardless of whether you owe any tax or pay it on time. In the event that you do not file and pay by 1 May 2023, you will face additional daily penalties of £10 per day, up to a maximum of £900. If the return still remains outstanding, further penalties will be charged after six months and again after twelve months from the filing date. There are also additional penalties for paying late that amount to 5% of the tax unpaid at 30 days, 6 months and 12 months.

If you are filing online for the first time you should ensure you register to use HMRC’s Self-Assessment online service.
