2025 Tax tables already in MYOB payroll

Query from our Payroll team - the amount is minor but:

It looks as though they have started using the 2025 tax tables early.

We are processing the 18-24 Mar pay run (pay day 25 Mar) and the PAYE amount is different from the previous week. And the difference is the ACC levy increase.

I understand that this is a minor amount for this client but they are a payday filing client so we would not have expected them to have to adjust the amount to pay until next week.

I would like an explanation as to why the 2025 tax tables are being used for a 2024 pay period and payment date.

Thanks
