If you need to complete a 2021-22 tax return but haven’t submitted one before, you’ll need to register with HMRC to get your ten-digit Unique Taxpayer Reference (UTR), which is a piece of information you’ll need in order to complete your tax return.
The last tax year started on 6 April 2021 and ended on 5 April 2022. The deadline for letting HMRC know that you need to submit a tax return for the last tax year is 5 October 2022. You can do this by registering for Self-Assessment.
The deadline for filing a paper tax return for the 2021-22 tax year is 31 October 2022, and the deadline for filing an online tax return is 31 January 2023. The deadline for paying the tax you owe, whether you’ve submitted via post or online, is also 31 January 2023.
You may also be required to make payments on account, which are advance payments. If so, this second payment deadline is 31 July 2023.
According to HMRC, you can’t file a tax return online for the things listed below. Instead, you’ll have to use commercial software or download other forms
· a partnership
· a trust or estate
· if you lived abroad as a non-resident
· to report multiple ‘chargeable gains, for example from life insurance
· if you get income from a trust, you’re Lloyd’s underwriter or a religious minister
One benefit of filing your tax return ahead of the deadline is that you’ll know how much you owe, giving you more time to budget and plan your finances. By filing earlier, you could also get refunded quicker if you’re owed a refund.
