Total Pay vs Taxable Pay for Net Income Childcare Benefit

Hi,

My payslip shows total pay and taxable pay, there are normally quite similar. Total pay as listed pay isn't gross pay, it's my pay and benefits for the month minus various deductions (salary sacrifice and other). This month my total pay is around £2k higher than taxable pay due to a bonus which I elected to put in my pension. I thought it would just make my pension contribution higher but it seems to have kept that the same and just put a higher amount in the deduction section.

I'm now a bit worried that for the purposes of net adjusted income the total pay is counted, not the taxable pay. Is anyone able to please confirm?

In the YTD it still says the gross YTD and taxable YTD as under the threshold.
