If payroll checks previously issued did not have a state (NJ) designation is there a way to go back to those checks to designate the state? The issue is for W-2's the State Gross is missing amounts for several payroll checks for which the state was not designated until after those several checks were issued. So the employees in question have amounts in the NJ taxable box but it does not match the Federal Gross by the those checks. Nothing has been filed yet so this is not a correction situation.
Any hep would be appreciated as it seems we are not able to go back and change those checks and we are trying to avoid voiding the originals and redoing them.
I'd like to help ensure you have an accurate information entered on your employee's W2 form.
To make sure you will not incur any problems with your 2018 tax forms like 941 and W2, what you can do is to create an adjustment check dated the same with the last payroll for 2018. Prior creating the adjustment check, you need to make sure you have updated the State Tax information of your employees and created a payroll item for it.
Lastly, since your employee's were overpaid on their payroll last year, you can create a deduction item with a tax tracking type of “None” and use it on their first payroll for the current year.
