Hi there,
QuickBooks Online makes it easy to change the GST filing period. I'll be happy to show you how.
From your left navigation panel, click Taxes > Retuns > Prepare Return > Adjust the filing period. I've attached a screenshot below for more clarification. Let me know if you have questions. Here's a helpful resource with more info on changing your report period. Check it out and don't hesitate to reach out if you need anything.
