Self Assessment
Registration Guide

​

There are a variety of reasons why you might be required to complete a Self-Assessment return. This includes if you are self-employed, a company director, have an annual income over £100,000 and / or have income from savings, investment or property.

 

Taxpayers that are required to complete a Self-Assessment return for the first time should inform HMRC by 5 October following the end of the tax year for which a Self-Assessment return needs to be filed. Here’s an example: 

Jane becomes a company director in June 2020. This means Jane needs to file a tax return for the 6 April 2020 - 5 April 2021 tax year because she became a director within that tax year. She must inform HMRC that she needs to register for self assessment by 5 October 2021. 

 

If you have missed the deadline for the 2020-21 tax year please notify HMRC and register as soon as possible by calling 0300 200 3310. You should also ensure that you file your 2020-21 tax return and pay any tax due by 31 January 2022. Alternatively, call us on 0800 161 5435 and we will be happy to assist you.

 

In certain circumstances, HMRC may also ask taxpayers to complete tax returns. HMRC has an online tool www.gov.uk/check-if-you-need-tax-return/ that can help you check if you are required to submit a Self-Assessment return.
