Probably not the best answer.  But here's what we did with the same situation last year.  In Payroll, Set up a new pay period, and Enter Checks, as a Second check for each employee impacted.  Zero out everything. In the employer tax portion enter the amount to correct the SUI (The difference between what it is on your report, and what it should be (-0.00)).  Make certain everything else is zeroed out, including direct deposits and all fringes.  Process and print 'fake' checks using whatever numbering system you use for other corrections that won't interfere with your normal check numbers.  Post this payroll as usual.  Your new report should reflect the correct amounts.

Steps are in Knowledge Base 21156, and there is a report attached to that Knowledge Base article that will give you the difference in the tax.  You will need to issue a zero dollar check.  All pays, deductions and employEE taxes will be zero, you will  just have the amount of the difference in the employER tax.   If it happened on several checks, you can enter one check for the full amount with a check date at the end of the quarter, you do not need to enter a second check for each pay period.  

Thanks [email protected], sounds great! I have also learned you can correct it making reverse entries into Job Costs. Depending on the number of entries, the process seems quicker. Thanks again for your response.

Thanks Rachel,
