2025 tax instalment payments: How instalments work in Canada

Last updated: Apr. 4, 2025 

Unfortunately, when it comes to instalment payments, the answer to this question is not so cut and dry.

Installment payments are typically calculated using your previous years’ net taxing owing. If your net tax owing was more than $3,000 ($1,800 for Quebec) for 2024, and in either 2023 or 2022, then you may need to pay instalments in 2025. However, this formula doesn’t take your current tax situation into account.

For example, let’s say you owed more than $3,000 in the past two years due to an unusual sell-off of investments, then the calculation would indicate instalment payments are due. However, if you do not owe any additional tax in the current tax year (maybe your employer remitted sufficient tax and/or there were no unusual gains), then instalments aren’t due at all – despite having owed more than $3,000 of net tax in prior years.

Below, we walk you through the ins-and-outs of instalments, including how to calculate them.

If you’re ever uncertain about whether you should pay your instalments, we recommend speaking with a tax specialist to ensure you avoid Canada Revenue Agency (CRA) interest or penalties.

What are tax instalment payments?

Instead of paying taxes in one lump sum on April 30 of the following year, instalments are paid during the same year as the income is earned.

As stated above, if your net tax owing was more than $3,000 ($1,800 for Quebec) for 2024, and in either 2023 or 2022, then you will need to pay instalments in 2025.

This can happen when your employer doesn’t withhold enough tax, if you’re self-employed or have more than one job, or if you have additional income sources from investments, rental properties, or certain pension payments.

When you go to file your taxes, you must claim the installment payments you made in the same year as you earned the income.

When are tax instalment payments due?

Tax instalment payments are typically due quarterly by the following dates: 

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

 If a due date falls on a Saturday, a Sunday, or a public holiday, the CRA considers your payment to be paid on time if it is received on the next business day. 

If your primary source of income is self-employment income from farming or fishing, you only have one instalment payment due date per year. You will receive an instalment reminder in November and must make your payments in the current year by December 31. 

Payments that are late or short of the full amount are subject to interest and penalty charges by the Canada Revenue Agency (CRA). 

How do I know if I have to pay tax by instalments?

The CRA will look at your prior-year tax return and send instalment reminders to you based on your prior returns. Although payments are typically due quarterly, the CRA will only send two instalment reminders:

• February reminder is for the March and June payments
• August reminder is for the September and December payments

You can find the amount you owe and the reminders online in your CRA My Account for Individuals or your CRA My Business Account.

Please note, if you’ve opted to receive an express Notice of Assessment (NOA), instalment reminders will also be electronically sent (i.e., not physically mailed).

 

How do I calculate my tax instalment payments?

According to the CRA, there are three different options you can use to calculate your instalment payments:

• No-calculation option: The option is best if your income, deductions, and credits generally stay the same each year. With this option, the CRA determines the amount of your instalment payments based on your latest assessed tax return.
• Prior-year option: If your 2025 income, deductions and credits will be similar to 2024, but significantly different from 2023, then determine the instalment payments based on your 2024 tax return.
• Current-year option: This option is best if your 2025 income, deductions and credits will be vastly different from those in 2024 and 2023. In this option, you determine your amount based on your estimated current year net tax owing.

The CRA has a chart to help you calculate instalment payments for the current year. Again, we recommend speaking with a tax specialist before calculating your instalment payments to ensure you’re meeting all your tax obligations.

What if my income level changes in the same year as I make instalment payments?

As stated above, tax instalments can be calculated using several different methods, including prior year amounts owed, most recent year, and/or an estimated current year amount.

If your income increases through the year, you may owe additional income tax when you go to file your return – even though you’ve already made instalment payments. If that’s the case, you are still obligated to pay the outstanding amount by April 30 of the following year.

If your business is cyclical and your income fluctuates greatly throughout the year, you may still be required to pay your instalments. If that’s the case, then it’s important to treat instalments as any other financial obligation – budget accordingly to pay the right amount at the right time.

Can I reduce or eliminate tax instalment payments?

There are two ways to reduce or eliminate your tax instalment payments:

1.You incur losses or generate little income in a given tax year
If you incur rental losses, capital losses or otherwise have little-to-no taxable income within a given tax year, you likely do not need remit instalments because you will not owe any taxes.

2. You are employed or receive pensions
If you’re an employee or receive certain pension payments, you can have tax withheld or increase the amount of tax deducted from these sources:

• Old Age Security
• Canada Pension Plan Benefits
• Employment Insurance or pension benefits

The CRA provides the following example of how this works:

• Hugh is a resident of Alberta and pays his tax by instalments. His net tax owing has been $3,500 for several years and he expects it will stay the same in 2025.
• He decides to have more tax withheld from his income in 2025. In January 2025, Hugh filled out Form TD1 to ask his pension plan administrator to withhold an extra $250 each month from his pension income.
• Hugh now estimates his net tax owing will be $500 for 2025. Based on his estimate, he does not have to make instalment payments in 2025 because his net tax owing will not be over $3,000 for 2025.

Instalment payments for farming and fishing

If your main source of self-employment income is from farming or fishing and you owe more than $3,000 in net tax, you only make one lump sum instalment payment on December 31.

You’ll receive an instalment reminder in November.

Instalment quick tips:

• Instalments are typically due quarterly: March 15, June 15, September 15, and December 15. If you work in farming or fishing, they’re due on December 31.
• If the instalment deadline falls on a weekend or holiday, the CRA considers it to be on time if it’s received by the next business day.
• The CRA will send you instalment reminders in February and August for quarterly payments, but it’s up to you to remember to pay them or you may face interest and penalties. Farmers and fishers will receive their reminder in November.
• You can find the amount you owe and the reminders online in your CRA My Account for Individuals or your CRA My Business Account.
• Payments can be made through your CRA account, through your financial institution, or by cheque as long as it’s postmarked by the instalment deadline. You can also choose to make pre-authorized payments.
• You must claim your instalment payments when you go to file your taxes for the same year in which you earned that income.

Determining whether you must pay instalments or not really boils down to your unique tax situation. Consulting with a tax specialist will ensure you apply the right strategy to meet your tax obligations while avoiding costly fees and penalties.

Commonly asked questions about tax instalments in Canada

Still have questions about how tax instalments work for your business? You’re not alone. Tax instalments can be confusing, especially when you’re trying to figure out whether you need to pay monthly or quarterly, or how your business structure affects your obligations. Let’s clear up some of the most common questions we hear from business owners.

How do corporate income tax instalments work under the Income Tax Act?

Under the Income Tax Act, a corporation must pay tax instalments if its total tax payable (federal and provincial/territorial) is more than $3,000 ($1,800 for Quebec) in the current year and in either of the previous two years.

The CRA offers three methods to calculate your instalments:

• No-calculation: CRA sends you amounts based on your last assessed return
• Prior-year: Based on last year’s actual tax payable
• Current-year: Based on your estimate for this year’s taxes

Corporate income tax instalments must be paid either monthly or quarterly, depending on your eligibility. This requirement applies to taxes before any refundable credits or amounts already withheld.

Do I have to make monthly or quarterly instalment payments as a corporation?

Most corporations must make monthly instalment payments, due on the last day of each month. You can qualify for quarterly instalments if your corporation meets all these requirements:

• You’re a Canadian-controlled private corporation (CCPC)
• You claim the small business deduction
• Your taxable income is under $500,000
• Your taxable capital employed in Canada is under $10 million
• You’ve maintained good tax compliance over the past 12 months

Quarterly instalments are due March 15, June 15, September 15, and December 15. Any final payment (remaining balance) must be paid by:

• 3 months after year-end for CCPCs eligible for the small business deduction
• 2 months after year-end for all other corporations

How do I calculate total tax payable if I have investment income or claim refundable tax credits?

Your total tax payable includes all corporate taxes owed after applying available tax credits (both refundable and non-refundable). If your corporation earns investment income such as dividends or interest, you may face additional taxes including:

• Refundable Part of Part I Tax
• Part IV Tax on portfolio dividends

These refundable taxes increase what you need to pay during the year, even though you might get some back later. Your instalments must reflect all income sources, including passive investment income. Failing to account for all sources can lead to interest charges or penalties.

The CRA’s Instalment Chart for Corporations (updated yearly) can help you calculate the correct tax amount for your specific situation.

What happens if I only make a partial payment or miss my balance due day?

Your balance due day falls either:

• 3 months after year-end for CCPCs eligible for the small business deduction
• 2 months after year-end for all other corporations

If you make only a partial payment or miss an instalment, you may face:

• Interest charges at the CRA’s prescribed rate (currently 10% annually as of Q2 2025)
• Instalment penalties, especially if you didn’t follow one of CRA’s approved calculation methods

Even if your estimate seemed reasonable, CRA may still charge interest if another method would have resulted in lower required payments. Any unpaid amount after your balance due day continues to accumulate interest daily until paid in full.

How do associated corporations and permanent establishments affect my corporate tax instalments?

Corporate relationships and business locations impact your tax obligations in specific ways.

For associated corporations:

• You must share the $500,000 small business deduction limit across your entire group
• Your combined taxable capital determines eligibility for quarterly instalments
• If your combined capital exceeds $10 million, all associated corporations must make monthly payments

If your business has a permanent establishment in multiple provinces or territories:

• You need to allocate income by jurisdiction
• Complete T2 Schedule 5 with your return
• Adjust your total tax payable to account for both federal and provincial/territorial taxes

These factors can increase your instalment obligations or change your eligibility for simplified payment schedules.
