Fill in Excess Pension to carry forward for next year tax year

Hi, I came to UK in 2020. My pension limit for a year is 40,000 pounds. I have paid 43,000 pounds and would like to carry forward 3000 pounds into the next tax year which is 2024-25. How do I do self assessment of this 3000 pounds to be carried over next year? In the sefl assessment section: Pension saving tax charges etc, I am confused how do you specify that I would like to carry over this excess into the next financial year? In this section "Pension saving tax charges et", I have put Amount saved towards your pension, in the period covered by this return, in excess of the Annual Allowance: 3000 pounds Annual Allowance tax paid or payable by your pension scheme:646.4 pounds. Can you please help me how can I carry forward the excess and where in the forms section should I specify this?

Hi VenuKelkar,
You cannot carry forward the £3000 as contributions are given relief only in the year they are paid.
You may have unused relief from previous years that you can use to avoid any pension tax charge as you have exceeded the annual limit. if you don't have any unused relief and need to pay the tax charge, it is the £3000 that you declare.
Pension savings — tax charges (Self Assessment helpsheet HS345)
Advises you how to work it out and complete your tax return.
Thank you. 

Hello HMRC admin, Thanks for replying here. I have unused pension amount from 2020. In 2020-2021 I have only invested 7000 pounds into my pension scheme. There is a deficit of 40000-7000 = 33000 for year 2020. Now with this, the 3000 from tax year 2022-2023 can be considered for the year 2020-2021. In this case, do I need to declare any amount in the section: "Pension saving tax charges etc" ? If yes, which boxes should I fill and what should be their amounts? Its a bit confusing. requesting your help to fill this up. Thanks and best regards.

Hi VenuKelkar,
The unused pension threshold from the 3 previous tax years, can be carried forward and added to the year in question.  
Eg.  22/23 can have unused threshold from the 3 previous years added to the threshold of up to £40000.  
The unused threshold cannot be carried back from 22/23 to an earlier year.
Thank you.
