Adjusted Net Income for childcare

I know how to work this out, but what period the projection of my income based on? I need to make circa £8k pension contributions to bring my adjusted net income below £100k and qualify - should this be for the 2024/25 tax year I need to be under £100k, or for the next 12 months from my application?

Hi
It would be for the tax year 2024/25.
