HMRC has confirmed that more than 11.7 million people submitted their 2021-22 Self-Assessment tax returns by the 31 January deadline. This included over 861,000 taxpayers who left their filing until the final day and over 36,000 that filed in the last hour before the deadline.

Whilst this was the highest ever number of filings, there are still an estimated 600,000 taxpayers that have missed the deadline and are yet to file. Are you among those that missed the 31 January 2023 filing deadline for your 2021-22 Self-Assessment returns?

If you have missed the filing deadline then you will usually be charged a £100 fixed penalty if your return is up to 3 months late, regardless of whether you owed tax or not. If you do not file and pay before 1 May 2023 then you will face further penalties unless you have arranged to pay HMRC.

If you are unable to pay your tax bill, there is an option to set up an online time to pay payment plan to spread the cost of tax due on 31 January 2023 for up to 12 months. This option is available for debts up to £30,000 and the payment plan needs to be set up no later than 60 days after the due date of a debt. This should be done sooner rather than later as a 5% late payment penalty will be charged if tax remains outstanding, and a payment plan has not been set up, before 1 April 2022.

If you owe self-assessment tax payments of over £30,000 or need longer than 12-months to pay in full, you can still apply to set up a time to pay arrangement with HMRC, but this cannot be done using the online service.

HMRC’s Director General for Customer Services, said:

‘Thank you to the millions of customers and agents who got their tax returns in on time. Customers who have yet to file, and who are concerned that they will not be able to pay in full, may be able to spread the cost of what they owe with a payment plan.’
