Hi Meegan,
Love your question!
You can unlock the pay run and make the change, but when you finalise it again, opt out from lodging it to the ATO from the pay run. Instead, please go to the Reports section in your Employees tab and click on Single Touch Payroll to create and lodge an update event.
Here is an article from our Payroll support website for your reference:
- Creating & Lodging an Update Event
Thank you and please let us know if you have any questions on following the steps in the article.
