Pension - self employed

[Happyinheels]

Hi, just trying to work out some pension forecasts and wondered if anyone could help.

Year 1 - contribution 4550
Government- 1137.50 (25%)
Total - 5687.50

Year 2 - contribution 7800

Would the governments contribution then be on my total ie the 5687.50 from year 1 plus the 7800 from year 2? Or would it just be on the year 2 of 7800 ie 1950?

Does that make sense?
Thanks in advance 😀

If I follow your Q, it would just be on Y2.

Thank you. So each year only on what I have put in in that financial year?
