How can I reduce my tax owed last year that I realised while doing self assessment now?

I am doing my self assessment for 2019-2020 now before the Dec 31st deadline. While doing so, I realised that I owe tax. Little had I known that in the tax year itself, I would have planned to reduce my tax burden. But I am here now. I've had a few sleepless nights looking at options.  For example, I cannot backdate my pension contributions to reduce my overall taxable income. I believe it was possible 10 years back. Are there any other options?

Hi, did you manage to do anything about it ? We do have exactly the same problem? Please let me know if is still posible to put money on the pension pot to reduce tax from 2019/20. Thank you

No, you cannot make pension contributions after 5 April 2020 and get tax relief for 2019:20.

How time flies. Pension payment carry back ended 31 January 2006.
