How to Pay GST/HST in Installments in Toronto?

Toronto businesses registered as annual GST/HST filers with more than $3,000 in net tax owing are required to pay GST/HST in installments throughout the year. The CRA divides this obligation into four quarterly payments due on March 31, June 30, September 30, and December 31. To pay, you calculate your installment amount using one of three CRA-approved methods, then submit each payment through online banking, CRA My Payment, or pre-authorized debit using payment code 476. 

This guide walks you through the entire process so your Toronto business meets every deadline and avoids installment interest charges. 

What Are GST/HST Installment Payments?

GST/HST installment payments are quarterly advance payments that certain annual filers must make to the CRA throughout the year. Instead of paying the entire GST/HST balance when the annual return is filed, the Canada Revenue Agency requires these businesses to pay in portions across the year.

This system exists because annual filers only submit one return per year, which means the CRA would otherwise wait a full year to collect tax that was already earned and collected from customers. Installments keep the revenue flowing to the government on a regular schedule. It is worth noting that installment payments are separate from your annual GST/HST return. You still need to file your return by the deadline even if all your installments were paid in full and on time.

Who Is Required to Pay GST/HST Installments in Toronto?

Not every Toronto business needs to make installment payments. The requirement applies specifically to annual GST/HST filers whose net tax owing for the previous fiscal year exceeded $3,000. If your business files monthly or quarterly, installments do not apply to you because you are already remitting tax regularly throughout the year. The installment obligation only affects annual filers who have a larger tax liability.

If your net tax for the previous year was $3,000 or less, you are not required to make installments. However, if your business grew significantly during the current year and you expect a higher tax liability, it is still a smart move to make voluntary installment payments to avoid a large lump sum at filing time.

How to Calculate Your GST/HST Installment Amounts?

The CRA gives annual filers three methods to calculate their quarterly installment amounts. You can choose the method that works best for your business situation.

Method 1: Prior Year Method 

Divide your net tax from the previous year by four. Each quarterly installment equals 25% of what you owed last year. This is the simplest method and is safe to use if your revenue has stayed relatively stable.

Method 2: Current Year Estimate Method 

Estimate your net tax for the current year and divide that by four. This method works well if your revenue has changed significantly from the prior year, but it requires a reasonably accurate forecast to avoid underpayment.

Method 3: First Instalment Method 

For the first installment, pay 25% of your prior year net tax. For the remaining three installments, base the amounts on your estimated current year net tax minus the first payment already made. This hybrid approach gives you flexibility as the year progresses.

How to Pay GST/HST Installments in Toronto? Step by Step

Once you have confirmed your obligation and calculated your installment amounts, the actual payment process is straightforward when you follow the right steps in order. 

Step 1. Confirm You Are Required to Make Installments

 Check your previous year’s GST/HST return. If your net tax owing exceeded $3,000, you are required to make installment payments for the current year. If you are unsure, log in to your CRA My Business Account where the CRA may have already sent you an installment reminder notice.

Step 2. Choose Your Calculation Method 

Select one of the three CRA-approved methods described above. For most stable Toronto businesses, the prior year method is the easiest and most reliable. Calculate your four installment amounts before the first due date of the year.

Step 3. Set Up Your Payment Method 

The CRA offers several ways to make GST/HST installment payments in Toronto:

• Online banking is the most common option. Add the CRA as a payee through your Toronto bank or credit union, use your GST/HST business number as the account number, and select “GST/HST Installment” as the payment type.
• CRA My Payment portal lets you pay directly using Interac Online through the CRA website without any additional account setup.
• CRA My Business Account allows you to initiate a pre-authorized debit directly from your business bank account, making it a fully automated and reliable option.
• In person at a financial institution is available if you prefer to pay at a branch counter. Simply bring your remittance voucher and the teller will process the payment on your behalf.

Step 4. Use the Correct Payment Code 

When making a GST/HST payment, the CRA uses payment codes to distinguish between different types of remittances. For installment payments, use payment code 476. Using the wrong code can cause your payment to be applied to the wrong account, which may result in a missed installment on the CRA’s records even if you paid.

Step 5. Keep Proof of Payment 

Always save confirmation of every installment payment you make. This includes your bank transaction record, CRA My Payment confirmation number, or pre-authorized debit confirmation. If a discrepancy ever arises with the CRA, your payment records are your first line of defense.

Step 6. File Your Annual Return on Time 

Installment payments do not replace your annual GST/HST return. Once your fiscal year ends, file your return by the deadline March 31, 2026 for corporations with a December 31 year end, or June 15, 2026 for individuals, with any remaining balance owing by April 30, 2026. Your installments will be credited against your total tax owing, and if you overpaid, the CRA will issue a refund.

What Happens If You Miss a GST/HST Installment Payment?

A missed or underpaid installment does not result in a separate penalty, but it does trigger installment interest. The CRA calculates this interest on the difference between what you paid and what you were required to pay, compounded daily from the due date until the balance is settled.

The interest rate on overdue installments is the CRA’s prescribed rate, which is reviewed quarterly. In recent years this rate has been high enough to make underpayment a costly mistake for Toronto businesses with significant tax liabilities. The good news is that if you overpaid an earlier installment, the CRA uses that overpayment to offset interest on a later shortfall. So staying ahead on your payments protects you even if one quarter comes in lower than expected.
