We must act with due diligence in refunding any net tax that a registrant claims on the required return.

If you file your return on or before the last day of a reporting period and you are not refunded the GST within 29 days after the last day of the reporting period, you will be paid interest calculated as of the 30th day following the last day of the reporting period until the day the refund is paid.

If you file your return after the last day of a reporting period and you are not refunded the GST within 29 days after the date we receive your return, you will be paid interest calculated as of the 30th day following the date we receive your return until the day the refund is paid.

In all cases, you will be paid a refund only if you have filed all the required returns for the reporting period and for all previous reporting periods. You may not receive the refund you claimed if you have a debt with the CRA. If this is the case, interest (if any) will stop accruing on the date the refund is applied to payment of the debt.

If you are not paid a QST refund within 45 days after the date we receive your return, you will be paid interest calculated as of the 46th day following the date we receive your return until the day the refund is paid. You may not receive the refund you claimed if you have a debt with us (including a GST debt). If this is the case, interest (if any) will stop accruing on the date the refund is applied to payment of the debt.

We can withhold a QST refund if you did not file all the required returns and reports under a Quebec fiscal law or a regulation made under such a law. You will not receive interest on the refund for the period the refund is withheld.
