I paid an employee early last year, and forgot to make a paycheck for the transaction. I need to create a paycheck, but can't go back in dates far enough. How can I?

Let me provide some information about creating paychecks in QuickBooks Online (QBO), aaron58.

We can create unscheduled checks for the current pay period up to the pay periods dating six months ago. However, the option to create a check with a date in the past is unavailable. The only available check dates are dates that fall after your last check date and before your next payday. This is to ensure to keep your payroll taxes error-free. Here's how:

1. Go to the  Payroll menu, then select Employees.
2. Tap Run payroll.
3. Find the employee you want to pay, and then select Create another check.
4. Enter employee compensation, including any salary adjustments, vacation or sick hours, and other pay types.
5. Confirm the pay period and check date.
6. Click Preview Payroll, and then hit Submit payroll. If creating a paper check, handwrite or print the check and give it to the employee by the check date.
7. Press Finish payroll.

If the same thing happens, I'd suggest contacting our Payroll Support Team to help you create the paycheck. To ensure we address your concern, our representatives are available from 6:00 AM to 6:00 PM on weekdays and 6:00 AM - 3:00 PM on Saturdays, PST. See our support hours and types for more details about this one. Here's how:

1. Go to the Help icon on the top right. 
2. Enter your concern in the search field.
3. Choose Talk to a human.
4. Click the OK. To get you to the right human, in a few words, tell me what you need help with option and tap I still need a human. 
5. Press Contact us.
6. Tick Continue. 
7. Choose Message an agent or Get a callback.
