If you are under special GST accounting periods, the deadline to submit your returns is one month after the cut-off date of the special accounting period. For example, if the GST return is for the special accounting period from 5 Apr 2012 to 5 Jul 2012, the due date to submit your return is 5 Aug 2012.

Penalties will be imposed if you are late in filing your GST return and making payment.

For GST refundable to you, it will be sent to your company via cheque or credited to your GIRO-linked bank account within a period equivalent to the prescribed accounting period after the return to which the refund relates is received by the Comptroller. For example, if you are under quarterly accounting cycle, the refund will be made to you within three months from the date the Comptroller receives your GST return. This does not apply under certain circumstances such as if you have outstanding GST returns which are not submitted, or if your GST return is being reviewed by our auditor.

Request for extension of deadline

All GST-registered businesses need to put in place systems to track their transactions, and to plan their resources to submit their GST returns on time.
