Current year option
- Payments are equal to your 2023 estimated net tax owing, Canada Pension Plan contributions payable and voluntary Employment Insurance premiums payable, in four equal instalments

Interest and penalty charges
The CRA may charge you substantial interest and penalties if you don’t pay the required instalments on time. Instalment interest is calculated at the CRA’s prescribed rate plus an additional 4%. The prescribed rate is set quarterly and approximates short-term money market rates set by the Bank of Canada.
With the recent interest rate hikes, the interest rate on overdue taxes is currently 9%.
The prescribed interest rate has not been this high since the fourth quarter of 2007, over 15 years ago. Remember that instalment interest charges are compounded daily, bringing the effective annual rate to over 9.4%. Note that this interest rate also applies to the unpaid balance from your 2022 tax return balance-due date until the date the balance is paid. If needed, you may be able to borrow funds from a financial institution at a lower interest rate.
In addition, CRA may charge a penalty on late or insufficient instalment payments. The penalty can apply if your instalment interest is more than $1,000. It is calculated by taking your actual instalment interest charges for 2023, subtracting the higher of $1,000, or 25% of the instalment interest that would be payable if you had not made any instalments for 2023, and then dividing the difference by two.
In Quebec, the current interest rate charged on amounts owing is 10%, and an additional interest of 10% per annum, compounded daily, is applicable where the amount of an instalment payment is less than 75% of the amount the taxpayer is required to pay.
Note that trusts (other than a graduated rate estate) may also be required to make instalment payments. However, the CRA’s administrative policy is that they will not assess penalties or interest where a trust fails to make sufficient instalment payments.
Ways to reduce or eliminate interest charges and penalties
If you’re behind on your March and June 2023 instalments, it’s not too late! You can reduce or eliminate the interest charges and penalties by overpaying your September and December instalments or paying them early. This is because the CRA will calculate a notional interest on early or excess payments that will be offset against interest charges on late payments. Since instalment penalties are charged on the net interest, they will also be reduced.
