Annual accounting requirements for an SME in Quebec: The complete checklist for 2026

At a Glance. An SME in Quebec must file returns with two tax authorities each year: the Canada Revenue Agency (CRA) at the federal level and Revenu Québec at the provincial level. An incorporated company must file a T2 return and a CO-17 return within six months of the end of its fiscal year; an unincorporated business reports its business income on the T1 and TP1 forms by June 15 at the latest, with any balance due payable as of April 30. In addition, there are GST (5%) and QST (9.975%) returns, source deductions if you employ staff, T4s and RL-1 slips by the end of February, the annual update with the Registraire des entreprises, and the retention of records for six years. Here is the complete checklist, with all deadlines.

Running an SME in Quebec means dealing with a compliance schedule that never really takes a break: two tax returns, taxes due several times a year, employer reports in February, an update with the Registraire des entreprises, and tax instalments in between. Every oversight results in penalties and interest charges. This 2026 guide compiles all the annual accounting obligations for a Quebec SME into a single checklist, including standard deadlines and best practices to ensure everything is covered. It complements our Startup Checklist for a New Business, which covers initial entries.

Why is the schedule of a Quebec SME so busy?

Quebec is the only province where a business deals with two separate tax authorities. Most obligations therefore exist in duplicate: a federal and a provincial tax return, source deductions remitted to both levels, and federal and Quebec pay stubs for employees. Annual compliance consists of four main categories:

• Income Taxes: Form T2 to the CRA and Form CO-17 to Revenu Québec for a corporation; Form T1 and Form TP1 for a self-employed individual or a partnership.
• Sales Taxes: The 5% GST and 9.975% QST, both administered by Revenu Québec, must be reported according to the frequency assigned to you.
• Employer obligations: Source deductions (DAS), T4 and RL-1 slips, employer summary, salary reporting to the CNESST, and contributions calculated based on total payroll.
• Administrative Requirements: Annual update with the Registraire des entreprises, bookkeeping and record-keeping, retention of supporting documents for six years.

The complete annual checklist, in a table

Here is the master list. The exact deadlines depend on your fiscal year-end, your corporate structure, and your status as an employer: use this table as a guide, then verify each date for your specific situation.

A detail that trips up many business owners: for a company, the issuance date (six months) and the payment date for the balance (two or three months) are not the same. Many SMEs file on time but pay late, and interest accrues from the payment date, not the filing date.

Income taxes: T2 (federal), CO-17 (provincial)

An incorporated company files two separate returns each year: the T2 with the CRA and the CO-17 with Revenu Québec, each within six months of the end of the fiscal year. The annual financial statements are submitted with the T2 form as a General Index of Financial Information (GIFI). The tax balance is due earlier: generally two months after the fiscal year-end, or three months for many Canadian-controlled private corporations eligible for the small business deduction. Most corporations also make tax instalments during the year, either monthly or quarterly, depending on their size.

What if your business isn’t incorporated?

A self-employed individual or business partner reports business income on their personal tax returns: the T1 form at the federal level and the TP1 form in Quebec. The filing deadline is June 15, but any tax balance is due as of April 30, and tax instalments may be required on March 15, June 15, September 15, and December 15 when the tax due exceeds the specified thresholds. The classic pitfall: filing in June under the assumption that payment will follow, even though interest has been accruing since the end of April.

GST and QST: Returns that come up throughout the year

As soon as your taxable sales exceed $30,000 over four consecutive calendar quarters, registration for the GST/QST becomes mandatory. In Quebec, Revenu Québec administers both taxes: you collect the 5% GST and the 9.975% QST (approximately 14.975% combined), you recover the taxes paid on your eligible expenses through ITCs and ITRs, and then remit the net amount.

• Annual frequency: Taxable sales of $1.5 million or less (default frequency); quarterly estimated payments may apply if your annual net tax exceeds $3,000.
• Quarterly frequency: Sales between $1.5 million and $6 million; the filing and payment are due one month after the end of the quarter.
• Monthly frequency: Sales exceeding $6 million, or at the company’s discretion, for example, to accelerate recurring repayments.

The detailed procedures (registration, ITC and ITR, zero-rated and exempt supplies, choice of filing frequency) are covered in our GST/QST Guide for Businesses in Quebec.

Employer: source deductions, statements, and CNESST

As soon as you hire your first employee, your schedule gets busier. Source deductions (DAS) are remitted at two levels: federal income tax and employment insurance to the CRA; Quebec income tax, the Quebec Pension Plan (QPP), the Quebec Parental Insurance Plan (QPIP), and employer contributions, including the HSF, to Revenu Québec. The annual cycle for a Quebec employer looks like this:

• Every month: Submission of source deductions forms to the CRA and Revenu Québec by the 15th of the following month for the standard filing frequency (earlier for companies with large payrolls).
• End of February: T4 forms for the CRA, RL-1 slips for employees and Revenu Québec, and a summary of employer withholdings and contributions.
• March 15: Submitting payroll reports to the CNESST, which is used to determine your insurance premium for the year.
• Throughout the year: Maintaining payroll records and updating withholding rates, which change every January 1.

Registraire des entreprises, books, and record keeping

Every business registered in Quebec must file an annual update with the Registraire des entreprises and pay its annual registration fees; for most corporations, this filing occurs at the same time as the Quebec income tax return. Regarding records, the law requires reliable accounting records (general ledger, bank reconciliations, payroll and tax records) and, for a corporation, an up-to-date corporate book containing annual resolutions and the register of directors and shareholders. Finally, supporting documents must be retained for six years after the end of the last applicable tax year, a requirement shared by both the CRA and Revenu Québec, either in paper form or in a readable digital format.

How much does annual compliance cost, and how can you ensure you cover everything without missing a step?

The good news: You can delegate this entire checklist. An accountant who is familiar with your files will handle the entire cycle (bookkeeping, taxes, payroll, filings, and the Registrar) and keep track of the schedule for you. It’s almost always less expensive than the penalties, interest, and lost hours associated with piecemeal compliance efforts.

In terms of budget, an SME pays a median of approximately $3,000 per year for accounting services, with most engagements ranging from $500 to $6,000 depending on transaction volume and the services included. Based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received; the Bankeo Fee Barometer breaks down these ranges by department and by industry. To ensure you cover everything without missing a thing, the easiest way is to be matched with an accountant whose services align exactly with your list of obligations: that’s exactly what Bankeo does, for free, and we’ll support you for as long as you need.

Frequently asked questions

What are the annual accounting requirements for a corporation incorporated in Quebec?

Each year, a Quebec company files a T2 with the CRA and a CO-17 with Revenu Québec within six months of the end of its fiscal year, pays its tax balance two or three months after the fiscal year-end, makes its tax instalments, files its GST and QST returns as required, fulfills its obligations as an employer if it has employees, files its annual update with the Registraire des entreprises, updates its corporate ledger, and retains its supporting documents for six years.

What is the deadline for filing form T2 and form CO-17?

Both filings must be submitted within six months of the end of the fiscal year: a company with a December 31 fiscal year-end has until June 30. Please note that the tax balance is due well before then, generally two months after the fiscal year-end, or three months for certain Canadian-controlled private corporations eligible for the small business deduction. Interest accrues as soon as the payment due date passes, even if the return is filed on time.

What are the deadlines for an unincorporated Self-Employed individual?

Your business income must be reported on your personal T1 and TP1 tax returns, which are due no later than June 15. However, any tax balance is due as of April 30, and tax instalments may be required on March 15, June 15, September 15, and December 15. If you are registered for the GST and QST, your tax returns are due according to your filing schedule.

What are an employer’s annual obligations in Quebec?

An employer remits source deductions to the CRA and Revenu Québec, usually by the 15th of the following month at the latest. By the end of February, the employer files T4s, RL-1 slips, and the summary of employer source deductions and contributions. By March 15, the employer must file its payroll report with the CNESST. In addition, there are contributions calculated based on the total payroll, including the contribution to the Health Services Fund.

How long must you keep your accounting records?

The general rule is six years after the end of the last applicable tax year, for both the CRA and Revenu Québec. Digital formats are accepted as long as they remain legible and complete. Certain corporate documents, such as the corporate book, resolutions, and shareholder registers, must be retained for the entire life of the business.

How much does it cost to hire an accountant to handle all these obligations?

An SME pays a median of approximately $3,000 per year for accounting services, with most engagements ranging from $500 to $6,000 depending on volume and services. Based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received. The Bankeo Fee Barometer provides details on these price ranges, and the matching process with a vetted accountant is free and non-binding for the business owner.
