@McClerk RE: How can I withhold FICA for one employee task but not another?
There isn't a way to get QuickBooks do that automatically. If an employee is subject to FICA taxes (almost all are) then it thinks all earnings are subject to the FICA taxes. Generally, QuickBooks doesn't automatically handle edge cases like this (I've actually never heard of this one before.)
In this case, the only way I can think of to make this work is tricky. To do this, I recommend creating a special paycheck just for the election work and on it overwrite both the employee and company FICA taxes to 0.00. Then, so that QuickBooks doesn't defeat your efforts and just add more tax to the next check, enter a liability adjustment for the employee and reduce the wages for all four of the FICA taxes, both company and employee, by the elections earnings amount. I think after doing that then your 941 and W-2 forms will work correctly.
