I need to void a payroll check from my QB Mac verison in 2017, however I switched in 2018 to Windows Desktop QB. I can see the paycheck in my bank register, however the employee was from 2017 and did not cash the check because he went to jail. How do I credit back this old, uncashed payroll check to balance out our register with my bank account?
See the rules for unclaimed wages in your state. Usually you're supposed to send the money to the state. While you can void the check to fix your register (that's all that's required if it never cleared and so you didn't mark it cleared) you will probably also need to remit the money to the state.
