Payroll additional tax deductions

Hi Faye, you’re spot on. To get this working, you’ll want to enter that extra amount in the Additional Tax field and set both the Federal and Provincial Total claim amounts to 0.00.

Setting those claims to zero is the key. It tells QuickBooks she’s already using her tax credits at her other job, so the system knows to start taxing her right away instead of waiting for her to hit an earnings threshold.

The reason you're not seeing it on their paystub is that the Additional Tax doesn't have its own separate line. Instead, it bundles into the Federal Tax (or Income Tax) and Provincial Tax totals. That's why you weren't seeing it as a distinct deduction.

To verify if it worked, during Review & Create Paychecks, when processing their payroll, click Open Paycheck Detail → Employee Summary section. The total tax withheld should match your Additional Tax amount + any system-calculated tax (now active with zero claims).
