Information you need
In your return, you need to declare how much GST you collected on sales, and how much GST you paid on purchases. It’s compulsory to e-file your GST F5 return via myTax Portal.
When to file
Most businesses are on a quarterly accounting period, which means they file a GST F5 every three months. However, you can ask to file monthly.
You must e-file your return within a month of the accounting period ending. (Check due dates on this IRAS web page). If there were no transactions, submit a nil return.
GST payments have to be paid when the return is filed. If you have an existing GIRO arrangement, the payment will be deducted on the 15th of the month following filing.
Getting a GST refund
If you paid more GST than you collected, IRAS will owe you a refund.
Refunds paid via GIRO may arrive within 7 days. Most other refunds arrive within 30 days, although cheques sometimes take longer.
