Filing Past Years of Self Assessment Tax Return

Hi, I registered Self Assessment for the tax year 6 April 2023 to 5 April 2024 and received a UTR number. Meanwhile, I received letters from HMRC informing me to complete a Self Assessment tax return for the tax year 2021-2022 and year 2022-2023 within 3 months. May I know how I could complete the tax return online (i.e. tax year 2021-2022 and 2022-2023)? I am not able to find the link when I login to my gateway profile. Where can I get that? Thank you.

Hi ,
 

After logging into your Personal Tax Account, click on the Self Assessment tile on the homepage. Select ‘ More details about your Self Assessment returns and payments’, then select the link ‘More Self Assessment details’. On the page that follows, select ‘Tax Return Options’, then choose the tax year you wish to file from the drop down menu. If any of these steps are not present, contact our online services by webchat or phone via : Technical support with HMRC online services    .  Thank you .
