Hello there, @bkramer1.
I'll ensure you can enter a credit amount for withholding tax to decrease the balance due.
If you want to decrease the credit amount due, you may need to enter a positive amount instead of a negative one.
You can refer to the following steps and the sample screenshots below for visual reference:
- Go to the Taxes menu, then select Payroll Tax.
- Locate the withholding tax you want to enter a credit amount and click Pay.
- Fill out all the needed information in the Add Tax payment section.
- In the Payment amount area, enter a positive amount.

- Then, click Submit payment to save changes.
Now, the amount due is reduced by $10 after we apply the positive amount.
