Changing GST Accounting Periods

When you register for GST, you are allocated quarterly GST accounting periods according to your financial year-end.

Depending on your business needs, you can write in to request for a change in filing frequency (e.g. change to monthly GST accounting period) via myTax Mail (log in to myTax Portal) or email.

Your GST accounting period may also be adjusted if there is a change in your financial year end
