Interest rates under Section 28 of the Tax Administration Act, RSQ, c.A-6.002. This is the interest that runs on any debt you owe to the Government of Quebec. Similarly, if you obtain a judgment for a sum of money against your debtor (or he obtains a judgment against you, as your creditor!), this is the "additional indemnity" interest which may be stipulated in your judgment, to ensure you are able to execute your judgment (or that the judgment may be executed against you) with interest beyond the simple 5% standard from the Civil Code of Québec.
The current interest rate as of October 1st 2011 is 6%. A new interest rate is fixed every three months, starting on January 1st.
