I have an interesting situation that maybe someone has a solution to. An employee receives an overpay in 2010 of $5K. The company asks the payroll service to redo that payroll to the lower gross pay amount and refile the quarterly and annual reports. The problem is the tax was already impounded based on a higher gross amount. The payroll service says there is no way to get that tax back. The payroll service W-2 no longer would reflect that tax on their payroll. The W-2 with the correct documentation about tax impounded is being invalidated.
Shockingly the payroll service says it has no way to document this for the IRS and state. So the risk here is that the taxes collected would not be properly credited to the taxpayer, and there doesn't seem to be any valid documentation of the taxes paid since the W-2 that does document the payment is being made invalid / corrected.
How do you correctly document this situation to the IRS and state, so that that taxpayer is properly credited for taxes impounded, while simultaneously having a corrected, lower gross salary reported?
