The refund will be made to you within a period equivalent to your prescribed accounting period, from the date the Comptroller receives your GST return.
Example: GST Refunds
If you are under a quarterly GST 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 when you have outstanding GST returns which are not submitted, or when your GST return is being reviewed by our auditor.
