For your adjusted net income calculations, you can deduct charity gift aid contributions from your total taxable income. So say for 2022-2023, do they allow you take take into account charity contributions from this year (2023-2024) into that calculation in a similar way they do for when doing your self-assessment for the tax year 2022-2023.
I wasn't sure if it was effectively the same thing or not. I am slightly over the £100K threshold for 2022-2023 and looking to bring this down by making a charity contribution this tax year, but wasn't sure if that counted towards your adjusted net income.
Apologies if there is another thread on this.
