If you have ever missed a CRA instalment deadline, you know the feeling. The Canada Revenue Agency charges interest on late or insufficient payments, and those charges add up fast. For many Canadian business owners, the biggest challenge is simply keeping track of the schedule: March 15, June 15, September 15, and December 15 for individuals, or monthly for corporations with large tax balances. This guide covers the [cra installment payments schedule canada], how to calculate what you owe, and practical ways to stay on top of your payments.

What Are CRA Instalment Payments?

CRA instalment payments are periodic payments made to the Canada Revenue Agency toward your expected tax balance for the current year. They are required when your net tax owing exceeds a certain threshold: for individuals, it is $3,000 (or $1,800 for Quebec residents) in 2024; for corporations, it is $3,000. The idea is to pay your taxes gradually throughout the year rather than in one lump sum after filing.

Who Needs to Pay Instalments?

You must pay instalments if your net tax owing is above the threshold in either of the two previous years. For example, if your 2023 balance was $4,000, you must pay instalments in 2024 even if your 2024 income ends up lower. The CRA will send you a reminder with a calculated amount, but you can choose your own method.

Instalment Payment Schedule

For individuals (including self-employed), the four quarterly due dates are:

  • March 15
  • June 15
  • September 15
  • December 15

For corporations, payments are due monthly, on the last day of each month, starting two months after the corporation's year-end. For example, a December 31 year-end corporation would start instalments on February 28 (or 29 in leap years).

How to Calculate Your Instalment Payments

You have three options for calculating instalment amounts. The CRA will send you a notice with the amount they calculate, but you can choose a different method if it saves you money.

Option 1: No-calculation Method (CRA's Calculated Amount)

The CRA calculates your instalment based on your previous year's tax return. You simply pay the amount shown on your instalment reminder. This is the simplest method, but it may result in overpayment if your income drops.

Option 2: Prior-year Method

You base each instalment on your net tax owing from two years ago. For example, for 2024 instalments, you use your 2022 tax balance. This method can work well if your income is stable or rising.

Option 3: Current-year Method

You estimate your current year's tax owing and pay one-quarter (for individuals) or one-twelfth (for corporations) each period. This requires forecasting your income and deductions. It can minimize overpayment but carries risk if your estimate is too low, leading to interest charges.

Table: Instalment Calculation Methods Compared

Method How It Works Best For Risk of Interest
No-calculation (CRA) Pay the amount CRA provides Simplicity, stable income Low if income stable; high if income drops
Prior-year Use tax balance from 2 years ago Stable or rising income Low to moderate
Current-year Estimate current year's tax Fluctuating income Higher if estimate is low

Example: Calculating Instalments for a Self-Employed Consultant

Consider a self-employed consultant in Ontario with the following tax balances:

  • 2022 net tax owing: $8,000
  • 2023 net tax owing: $12,000
  • Expected 2024 net tax owing: $10,000

Under the prior-year method, she would pay $8,000 / 4 = $2,000 per instalment. Under the current-year method, she would pay $10,000 / 4 = $2,500 per instalment. If she uses the prior-year method and her actual 2024 tax is $10,000, she will owe an additional $2,000 at filing but may avoid interest if she pays the balance by April 30. However, if her 2024 income spikes to $15,000, she could face interest on the shortfall.

How to Pay CRA Instalments

You can pay instalments through your bank's online bill payment, CRA's My Payment service, pre-authorized debit, or by mail with a cheque. For businesses, payroll remittances and GST/HST payments often follow separate schedules, so it is important to keep them distinct.

Setting Up Pre-authorized Debit

Pre-authorized debit (PAD) is the most hands-off approach. You authorize CRA to withdraw the instalment amount from your bank account on the due dates. You can set up PAD through My Account for individuals or My Business Account for corporations. This eliminates the risk of forgetting a deadline.

Common Mistakes to Avoid

One frequent error is mixing up instalment payments with other CRA obligations. Instalments are separate from payroll source deductions and GST/HST remittances. Each has its own schedule and remittance forms. Another mistake is assuming the CRA's calculated amount is always correct. If your income has dropped, you can pay less, but you must document your reasoning to avoid penalties.

Interest and Penalties on Late or Insufficient Instalments

The CRA charges interest on late or insufficient instalments at the prescribed rate, which is set quarterly. The rate is currently 9% (as of Q2 2024), compounded daily. This interest is non-deductible for individuals but deductible for corporations in certain circumstances.

How Interest Is Calculated

Interest is calculated on each instalment from its due date to the date of payment or the filing deadline (whichever is earlier). The CRA uses a formula that compares the total instalments paid to the amount that should have been paid under the best of the three calculation methods. If you underpay, interest accrues on the shortfall.

Avoiding Interest Charges

The safest way to avoid interest is to pay the CRA's calculated amount or use the prior-year method if it results in higher payments. If you use the current-year method, be conservative in your estimate. You can also make extra payments at any time to reduce future instalment amounts.

Using Accounting Software to Manage Instalments

Manually tracking instalment due dates and amounts across multiple clients or your own business is tedious. Many Canadian CPA firms and small businesses use cloud accounting software to automate reminders and reconcile payments. Awditify's small business platform includes instalment tracking within its tax management features. You can set up recurring reminders, record payments, and generate reports showing your instalment history. For accountants managing multiple clients, the practice management tools allow you to monitor all instalment schedules from one dashboard.

Scenario: A Two-Partner CPA Firm

A two-partner CPA firm in British Columbia handles tax compliance for 200 clients. Before using a centralized system, the partners manually tracked instalment due dates on a spreadsheet. They missed one March deadline for a corporate client, resulting in $400 in CRA interest. After switching to Awditify for accounting firms, they now receive automated alerts for each client's instalment dates and can record payments directly in the client's file. The audit trail keeps a record of every payment, which helps during reviews.

Frequently Asked Questions

What is the CRA instalment payment schedule for individuals?

For individuals, the quarterly due dates are March 15, June 15, September 15, and December 15. These apply if your net tax owing was above $3,000 ($1,800 for Quebec) in either of the two previous years. The CRA will send you an instalment reminder with the amounts.

How do I calculate my CRA instalment payments?

You can use one of three methods: the no-calculation method (pay the amount CRA provides), the prior-year method (base on your tax balance from two years ago), or the current-year method (estimate the current year's tax). The prior-year method is often the simplest and safest.

What happens if I miss a CRA instalment deadline?

The CRA charges interest on late or insufficient instalments at the prescribed rate, currently 9% compounded daily. Interest accrues from the due date until the payment is made or the filing deadline. There are no late-filing penalties for instalments alone, but interest can add up quickly.

Can I change my instalment payment method during the year?

Yes, you can switch methods at any time. If you realize your current-year estimate was too low, you can increase subsequent payments or make a lump-sum payment to reduce interest. Keep records of your calculation method in case the CRA asks.

How can I automate CRA instalment payments?

You can set up pre-authorized debit through CRA My Account or My Business Account. For a more integrated approach, use accounting software like Awditify that tracks instalment due dates, sends reminders, and records payments. This reduces manual work and helps avoid missed deadlines.

What to Do Next

Understanding the CRA instalment schedule and choosing the right calculation method can save you significant interest and stress. The key is to set up a system that works for your situation: pre-authorized debit for simplicity, or a conservative current-year estimate if your income fluctuates. For accountants and business owners managing multiple obligations, a dedicated Canadian platform like Awditify can centralize instalment tracking, payroll, and GST/HST remittances in one place.
