I'll be sharing some insights to help you adjust employee YTD earnings in QuickBooks Online Payroll (QBOP).
To correct the payroll now that the YTD figures are entered, you'll need to roll back, re-run, and re-submit it as a correction to an earlier submission. This process will overwrite the existing submission with HMRC for that period.
Once payroll has been submitted in QBOP, the option to make changes will no longer be visible in your account. In this case, if any changes need to be made, the payroll support will help you correct them in future pay runs or you can use the HMRC PAYE tools if necessary. Any current tax year payruns will be available at an employee level but are static and cannot be amended. Any corrections should take place in the following payrun.
