Penalties and Interest

If you owe money to Revenu Québec, you must pay the debt by the deadline prescribed by law to avoid incurring interest and penalties

However, if you cannot pay the entire amount owed in one lump sum, you can always propose a payment agreement based on your ability to pay.

Any overpayment you make will be refunded with interest if the refund is made after the deadline prescribed by law.


Interest on debts and interest on refunds granted under Québec tax laws is capitalized daily on amounts owing.


Under the GST system, different interest rates are applied to amounts owing or refunds. The rates are given on the Prescribed interest rates page of the Canada Revenue Agency website.

Cancellation of interest, penalties or charges 

In specific situations, Revenu Québec may cancel interest, penalties or charges at your request.
