Canada has two layers of corporate law, federal and provincial, and two layers of tax, national and provincial. A company can be incorporated federally under the Canada Business Corporations Act (CBCA) or under a provincial statute, such as the Ontario or British Columbia business corporations acts. Each route has its own registry and annual obligations, while the Canada Revenue Agency (CRA) administers the main taxes.

This guide covers the private corporation, which is the usual vehicle for founders and for foreign-owned subsidiaries. It also explains where a branch, an unlimited liability company or a partnership differs. It is written for founders and for legal, finance and operations teams who need a clear annual view.

Entity compliance Canada: the quick answer

• File the annual return with the corporate registry. For a CBCA corporation, this is due within 60 days after the anniversary date, together with information on individuals with significant control.

• File provincial annual returns where the corporation is registered or extra-provincially registered. Dates and fees vary.

• File the T2 corporate income tax return within six months after the tax year-end, and pay any tax balance earlier.

• File information returns, such as the T106 for transactions with non-arm's length non-residents.

• Register for and file GST/HST returns if the business is a registrant, and keep payroll remittances current.

• Maintain the minute book, registers and the register of individuals with significant control.

What determines a Canadian corporation's compliance requirements?

The statute under which the corporation exists comes first. A CBCA corporation reports to Corporations Canada. A provincial corporation reports to its provincial registry. A corporation that operates in other provinces must usually register there too, and each registration has a separate annual return.

Next is the tax profile. Corporations that are Canadian-controlled private corporations (CCPCs) have access to the small business deduction and some different payment dates. A corporation controlled by non-residents is not a CCPC, so a foreign-owned subsidiary generally falls under the general rules. Finally, the size and activity of the business affect sales tax registration, payroll, audit requirements and sector licences.

Annual entity requirements in Canada: the core checklist

1. Corporate annual return and individuals with significant control

Every CBCA corporation must file an annual return with Corporations Canada. The deadline is within the 60 days following the corporation's anniversary date, meaning the date it was incorporated, amalgamated or continued under the CBCA. Since 22 January 2024, corporations must also file information on individuals with significant control (ISC) at the same time. An individual with significant control is generally a person with direct or indirect control over 25 percent or more of the votes or of the fair market value of the shares, or with influence that amounts to control. Corporations must keep an ISC register and update it as ownership changes.

Provincial corporations follow their own annual return rules. Some provinces tie the return to the tax filing or the anniversary date, and others have set annual dates. A foreign-owned subsidiary with provincial registrations in several provinces should list each date in the calendar.

2. Financial statements and audit

Corporations must prepare annual financial statements and present them to shareholders. Under the CBCA, a private corporation that is not a distributing corporation can usually dispense with an audit if all shareholders consent in writing each year, subject to the statute and its articles. Provincial laws differ, so confirm the rule that applies. Foreign parents often require an audit or review anyway for group reporting.

3. Annual shareholder meeting or resolutions

Corporate law requires an annual meeting of shareholders within set periods after year-end, to receive the financial statements, elect directors and appoint an auditor if one is required. Private corporations commonly satisfy this through written resolutions signed by all shareholders. Keep signed resolutions in the minute book.

4. Directors, officers and registers

Corporations must keep registers of directors, officers, shareholders, securities transfers and individuals with significant control. Changes in directors or officers are reported to the registry within the time allowed, usually within 15 days for a CBCA corporation. Residency requirements for directors vary by statute and over time, so confirm them for the corporation's governing law.

5. Registered office and records

The corporation must have a registered office in its jurisdiction of incorporation and keep the records there or at another disclosed place. Many foreign-owned subsidiaries use their law firm or a registered office provider. Check that mail is forwarded and monitored, because registry notices create deadlines.

Tax and indirect tax obligations

The T2 corporate income tax return is due six months after the end of the tax year. The balance of tax is generally due earlier, two months after the year-end, or three months for qualifying CCPCs. Instalment payments may be required during the year. Late filing penalties are significant and rise for repeat failures.

Corporate income is taxed federally and provincially, and the combined rate depends on the province and on whether reduced small business rates apply. A foreign-owned subsidiary should model the general combined rate for its province.

Goods and services tax and harmonized sales tax (GST/HST) apply to most supplies. A business must register once taxable supplies exceed the small supplier threshold, or sooner if it chooses. Registrants file returns monthly, quarterly or annually depending on revenue. Quebec and some provinces also have their own sales taxes with separate filings. Payroll deductions, including income tax, Canada Pension Plan and employment insurance, are remitted regularly, and the T4 information return summarizes the year.

Foreign-owned subsidiaries

Foreign ownership brings several extra items. The T106 information return reports transactions with non-arm's length non-residents above a reporting threshold, and it is due with the same six-month timing as the T2. Intercompany loans, management fees and royalties need transfer pricing documentation, and withholding tax applies to many payments to non-residents, with treaty rates reducing the statutory rate where the paper requirements are met. The payer files the NR4 information return for these payments. A Canadian corporation that owns foreign affiliates files the T1134, and Canada has thin capitalization limits on interest paid to related non-residents.

Establishing or acquiring a Canadian business triggers the Investment Canada Act. A non-Canadian investor must notify the government after establishing a new business, and larger acquisitions require review. National security review can apply to investments of any size in sensitive sectors. These rules are about the investor, so involve counsel before the transaction.

First-year and event-triggered obligations

In the first year, the corporation is incorporated and receives its certificate, issues shares, appoints directors, opens a CRA business number with the relevant program accounts, registers for GST/HST and payroll if needed, registers in other provinces where it operates, and makes the Investment Canada filing if required. Choose the fiscal year-end deliberately, because it sets the T2 and information return dates.

Events that trigger filings include a change of directors or officers, a change of registered office, a name change, a share issue or transfer that changes ISC information, an amalgamation, a continuance and a dissolution. Most have short registry deadlines. A dormant corporation still files annual returns and tax returns until it is formally dissolved.

Employment and local requirements

Employment standards are mainly provincial, so minimum wage, holiday pay, notice and termination rules depend on where the employee works. Employers must register with the provincial workers' compensation board in most provinces, and some provinces require health taxes or training levies. Quebec has distinct language, payroll and tax rules, and businesses there should plan for French-language requirements. Federally regulated industries follow the Canada Labour Code. Many foreign-owned subsidiaries hire a payroll provider to manage the filings and remittances.

Build a compliance calendar for Canada

A compliance calendar turns the rules above into dated tasks with named owners. Start from the financial year-end and the incorporation anniversary, then add the recurring monthly and quarterly items. Review it each quarter, because deadlines, extensions and registry systems change.

• Within 60 days after each anniversary date: CBCA annual return and ISC information, plus provincial returns on their own dates.

• Two months after year-end: pay the corporate tax balance (three months for qualifying CCPCs).

• Six months after year-end: file the T2 and the T106 if it applies.

• Monthly or quarterly: GST/HST returns and payroll remittances.

• February: T4 and related information returns for the prior calendar year.

• As needed: director changes, Investment Canada notices and registry amendments.

Common mistakes

• Assuming the federal annual return covers provincial registrations.

• Missing the ISC update when ownership changes at the parent level.

• Treating the T2 filing date as the payment date.

• Forgetting the T106 for intercompany transactions with a foreign parent.

• Paying management fees or interest abroad without checking withholding and the NR4 return.

• Registering for GST/HST late and owing tax that was never collected.
