Self-Employed Tax Instalments in Canada: When You May Need to Pay
Self-employed Canadians may need to pay income-tax instalments during the year. Learn how CRA eligibility, dates, calculation options and records fit together.
Self-employed Canadians may need to pay income-tax instalments during the year if their tax owing is high enough and they also owed more than the applicable threshold in a previous year. The CRA looks at your province or territory of residence and your net tax owing for the current and previous tax years. Your business income, expenses, other income, tax credits and amounts already paid can all affect the result. Review the CRA’s current instalment criteria before deciding whether a reminder applies to you.
What income-tax instalments are
Income-tax instalments are payments made to the Canada Revenue Agency throughout the year while you earn income. They help cover tax that might otherwise be payable as one larger balance after the year ends. Unlike payroll deductions taken from an employee’s pay, self-employed income generally does not have income tax withheld automatically. The CRA describes instalments as payments made during the year in which the taxable income is earned.
Instalments are separate from filing your income-tax return. Paying instalments does not remove your obligation to report your business income and expenses, and it does not determine your final tax liability. Your return still has to reflect your actual facts and records for the year.
When self-employed Canadians may need instalments
For 2026, the CRA says you generally have to pay income tax by instalments if both of these conditions apply:
- Your estimated net tax owing for 2026 is more than $3,000, or more than $1,800 if you are a Quebec resident; and
- Your net tax owing was also more than the applicable threshold in either 2025 or 2024.
The CRA’s “Who has to pay” page explains these current-year and prior-year conditions. The applicable threshold depends on where you live on December 31. A person living outside Quebec uses the $3,000 threshold, while a Quebec resident uses the $1,800 threshold shown by the CRA for this purpose.
Self-employment income is one common reason a person may have tax to pay without enough tax withheld during the year. However, instalment obligations are not limited to business income. The CRA also identifies rental income, investment income, certain pension payments and income from more than one job as situations that may result in insufficient withholding. See the CRA’s explanation of why instalments may be required.
What the CRA instalment reminder means
The CRA generally sends an instalment reminder to people who are likely to have to make instalment payments. The reminder suggests an amount and shows calculation options. For 2026, the CRA says the February reminder covers the March and June payments, while the August reminder covers the September and December payments. You can also view reminders in your CRA account. Check the CRA’s current reminder information.
A reminder is useful, but it is not a substitute for reviewing your own facts. The CRA’s suggested amount is based on information available to it, while your current business may be growing, slowing down, changing expenses or receiving income from several sources. Eligibility and the appropriate payment amount depend on your circumstances and the records supporting them.
When instalment payments are due
For most individuals required to make instalments in 2026, the payment dates are:
- March 15
- June 15
- September 15
- December 15
If a due date falls on a Saturday, Sunday or a CRA-recognized public holiday, the CRA considers the payment on time when it is received on the next business day. Confirm the current instalment dates and weekend or holiday rule on Canada.ca.
Special timing for farmers and fishers
If your main source of income is self-employment income from farming or fishing, the CRA says you have one instalment due date rather than the usual quarterly schedule. The current due date shown by the CRA is December 31. The farming and fishing rules can involve additional conditions, so review the CRA guidance if they apply to you. Read the CRA’s exceptions to quarterly instalment dates.
How to choose an instalment calculation method
The CRA provides three calculation options. The best option depends on whether your income, deductions and credits are stable or changing.
1. No-calculation option
This option uses the amount shown on your instalment reminder. It may be easier to follow when your income and tax situation are broadly similar from year to year. The CRA explains how the no-calculation option works.
2. Prior-year option
This approach uses information from the previous tax year. It may be relevant when your current-year income, deductions and credits are expected to resemble the previous year but differ significantly from the year before that.
3. Current-year option
This approach estimates the current year’s net tax owing and certain other amounts identified by the CRA, such as CPP contributions payable and voluntary EI premiums. It may be useful when your business has changed substantially, but it requires a reasonable estimate supported by current records. Review the CRA’s descriptions of all three options before changing the amount shown on your reminder.
Choosing an option is not the same as creating a deduction or reducing the tax you ultimately owe. It changes how you make payments during the year. If your estimate is too low, the CRA may charge instalment interest or a penalty in the circumstances described on its website.
What can happen if payments are late or too low
If you are required to pay instalments, receive a reminder showing an amount and do not pay, pay late or pay less than required, the CRA may charge instalment interest. The CRA says this interest is compounded daily at the prescribed interest rate, which can change every three months. See the CRA’s current explanation of instalment interest.
A penalty may also apply in limited circumstances. The CRA states that the instalment penalty applies only when instalment interest for the year is more than $1,000. The calculation is based on the CRA’s rules and the payments that should have been made. Do not assume that receiving a refund in another year automatically prevents interest or penalties; the relevant facts and payment history matter.
The CRA also explains that paying a later instalment early or paying more than required may reduce or eliminate some interest and penalty charges. Any credit interest described by the CRA is not refundable and can only be used against certain interest charges for the same tax year. Read the CRA guidance before relying on this approach.
Practical example: a changing freelance business
Imagine a freelance designer living outside Quebec. In the previous year, the designer had steady business income and received a CRA instalment reminder. During the current year, several contracts ended, revenue declined and some ordinary business costs increased. The designer should not automatically assume that the reminder amount still reflects the current situation.
A practical review would involve updating the income records, organizing expense documents, checking other income and considering whether the current-year calculation option is appropriate. The designer would then compare the estimate with the CRA’s current instalment criteria and keep a written record of the assumptions used. If the estimate is uncertain, professional tax advice may be appropriate. The example does not establish whether instalments are required or what amount should be paid; those conclusions depend on the person’s complete tax facts and records.
How to pay and verify an instalment
The CRA says individuals can pay instalments online, in person or by mail. If paying in person or by mail, an instalment remittance voucher may be needed so the payment is applied to the correct account. Review the CRA’s payment methods and voucher instructions.
Keep proof of each payment until you confirm that it appears in CRA My Account or receive the relevant instalment payment summary. The CRA advises allowing three business days for online payments and 10 business days for payments by cheque or money order before checking whether a payment has been processed.
How instalments appear on your tax return
Instalments are reported as tax paid, not as a business expense. The CRA says the total instalment payments for the tax year are claimed on line 47600 of the corresponding income-tax return. You can use the CRA’s instalment reminder, instalment payment summary or CRA account records to confirm the amount. If a payment is missing from the CRA’s records, keep proof and follow the CRA’s instructions for including it. See the CRA’s line 47600 guidance.
Record-keeping checklist for instalment planning
Good records help you estimate current-year income and expenses, compare your results with prior years and verify payments. The CRA requires business records that support income and expense claims, and generally requires them to be kept for at least six years from the end of the last tax year to which they relate. Review the CRA’s business-record requirements.
- Record business income by date, amount and source.
- Save sales invoices, contracts, fee statements, receipts and deposit records.
- Record business expenses promptly and retain receipts or other supporting vouchers.
- Separate personal and business transactions where practical.
- Track other income that may affect your total tax position, such as investment or rental income.
- Keep CRA instalment reminders and payment summaries.
- Save payment confirmations, bank records and remittance voucher details.
- Reconcile payments to your CRA account after the processing period.
- Document the assumptions used if you estimate current-year income.
- Keep records in a readable electronic or paper format.
Your next step
Sign in to your CRA account and locate your latest instalment reminder and payment history. Then update your year-to-date business income, expenses, other income and tax information using your records. Compare your estimate with the CRA’s current eligibility rules and calculation options before making, changing or stopping an instalment payment. If your situation is complex, ask a qualified Canadian tax professional to review the facts.
