NHS PENSION

So i submitted my self assessment tax return by 31st jan 2024. I am self employed I did not account for all my pension paid (both by myself and those i completed work for) How can i submit these payments to HMRC, and will I be due a refund?

Hi,
​​​​​​If you are a higher rate tax payer and paid into your pension scheme, you will want to claim personal pension relief.  
You should declare the amount you paid into your pensoin, plus the tax relief claimed by your pension provider in box1 of page TR4, or the online equivalent.
Thank you.
