New tax tables are not being applied to the employees

Hi chrischeah,

Welcome to Quickbooks Community.
We can check on the Pay Category being used by going to the employee record > Pay rates page. You will see a red box around a pay rate field which means the rate displayed is not the rate that will be paid in a pay run. The reason varies on different scenarios, to have a better illustration on this, please refer on this article to guide you on how to correct the pay rates: https://support.yourpayroll.com.au/hc/en-au/articles/360003111835-Why-are-the-rates-on-an-employee-s-Pay-Rates-page-NOT-what-the-employee-is-being-paid-

I hope this helps.  Thanks for stopping by.
