How to make an additional payment
If you have underpaid a payroll tax payment, and it is too late to cancel the submission, you will want to submit the difference as soon as possible. If this was due to additional checks that needed to be run, you can set the paid through date in the tracking setup back to what it was before the original payment.
To set your paid through date back on a payment already made, go to the tracking page of the relevant jurisdiction. In this example we will use US Withholding.
Note that the date entered into this field is telling the system what date you have paid through. Therefore, if the check date that you need to submit an additional payment is 2/1/2024, as seen below, select the check date immediately prior to the desired check date; in this example, that would be 1/16/24. This will set the 2/1/2024 check as the payment to be made.
Importantly, when you are making your additional payment, make sure to edit your totals to remove the amount already paid so that only your desired additional amount will be paid.
