I know!
Generally, the only time you should void a paycheck is if the paycheck shouldn't exist - if it was created by accident and you didn't pay the employee with that check.
In your case it sounds like the paychecks are legitimate, that they contain payroll information and pay that actually happened, and that you need give the employee a current-dated check so they can deposit it (because for some reason they did not do so at the time they were paid).
If so, the best thing to do is to create a replacement check for the employee without altering the prior paycheck at all. To do this,
- Create a standard bank check (not a paycheck) dated today, for the net amount of the paycheck you want to replace.
- In the Expense field on the check voucher area, enter the same bank account as you're writing the check from. Also, perhaps add a memo to the check explaining what it is.
- Save the check. You might get a nagging message that what you're doing is odd. Ignore it.
Once you've saved it, you'll have two new entries in your bank account register, one a check and the other that looks like a deposit. Net, the check won't actually impact your bank balance.
Later when you reconcile the account, select both the old uncleared paycheck and the 'deposit' created by the new one. Again, they will cancel each other out. You can even do a fake reconciliation just to mark these paired transactions as cleared. If you do that, then in the reconcile window make the ending balance the same as the beginning balance, as you expect a 0.00 net change as a result of such a reconciliation.
