I just realized that the dates for my payroll periods are off by one day. How can I update the records to reflect the correct dates?

Hi, dawnrplante. Ensuring payroll periods align with timesheets is important, and it's commendable that you’ve identified and are addressing this discrepancy.

To begin, we'll add a new pay schedule for the correct pay periods since existing ones can't be edited directly. Please note that updating payroll transactions from previous pay periods will depend on whether these transactions were processed using paper checks or direct deposits. I'd be glad to provide more details to help you update the paychecks with the incorrect pay periods in QuickBooks Online (QBO).

Here are the steps to add a pay schedule with the correct pay period for each employee: 

1. In your QBO account, go to Payroll. Then, Employees.
2. Select your employee. 
3. From Employment details, select Edit.
4. From the Pay schedule dropdown, click + Add pay schedule.
5. Choose the Pay frequency for the employee.
6. In the Next payday box, choose the previous periods where you want to start editing the previous payroll transactions with the incorrect pay period.
7. Select the correct End of next pay period.
8. Review the accuracy of the Upcoming pay periods on the right panel. Then, input a Pay schedule name to distinguish it from other pay schedules.
9. Select Save. Then, Done.
10. Repeat steps 1-3 for the rest of your employees. Then, choose the pay schedule you created from the drop-down list.

If these payroll transactions from previous pay periods are processed using paper checks, you can delete and recreate them. You can follow these steps:

1. Go to Payroll. Then, Employees.
2. Select Paycheck list. 
3. Click on the Filter button. Then, select the Date range of the payroll transactions at issue. 
4. Click on Apply.
5. From the Action column, select the drop-down arrow for each of the paychecks. Then, hit Delete.

Once done, run payroll for the previous payroll transactions.

However, if you've processed the previous payroll transactions using direct deposit, our phone/chat payroll support team can assist you in updating the paychecks to the correct pay schedule with the correct pay period. You can refer to this article to contact them: Contact Payroll Support.

For future reference, you may want to verify past payroll records that might have been affected by the incorrect dates. I'm adding this article about running payroll reports in QBO: Run payroll reports.
