Corporation or general partnership (SENC)

You’re starting a business with two or more partners and need to choose your business structure: incorporate a corporation or form a general partnership (SENC). Both allow you to go into business together and share profits, but everything else differs: who pays taxes, who is liable for debts, how much the structure costs, and what happens when a partner leaves.

The financial implications add up quickly. A partner taxed at the maximum personal rate pays up to about 53% on their share of a SENC’s profits, whereas a corporation eligible for the SME rate pays about 12% in Quebec in 2026: every $100,000 left in the business can represent around $40,000 in deferred taxes. And when it comes to risk, a single lawsuit or operating debt can put the homes and savings of a SENC’s partners at risk.

Here’s a comprehensive comparison, backed by 2026 figures, to help you decide based on your profile: risk tolerance, income, number of partners, and growth outlook. And if you’re still unsure, we’ll connect you for free with a vetted accountant who will run the numbers based on your actual figures.

A corporation is a separate legal entity : It owns its own assets, signs its own contracts, and pays its own taxes. Your liability is limited to your capital contribution, and the structure provides access to the combined SME tax rate of approximately 12.2% in Quebec in 2026 (9% federal, 3.2% provincial) on the first $500,000 of eligible active income. Profits retained within the corporation are not taxed in your hands until they are distributed: this is tax deferral, the key benefit of incorporation.

The trade-off is the administrative burden: articles of incorporation, corporate ledger, annual T2 and CO-17 filings, financial statements, and updates to the registry. Startup costs and recurring fees are higher, and the small business deduction in Quebec requires meeting eligibility criteria, including a threshold for paid hours.

• Advantages: limited liability, an SME tax rate of approximately 12%, tax deferral, choice between salary or dividends, and a lifetime capital gains exemption ($1.25 million or more) upon the sale of eligible shares.
• Drawbacks: higher formation and maintenance costs, more burdensome annual requirements, and a longer process to wind up the company properly.
• Who it’s for: those with profits exceeding their living expenses, those in high-risk industries (lawsuits, debt, large contracts), those planning for growth or a future sale, and partners who want to define their rights through a shareholders’ agreement.

A SENC brings together two or more partners who operate a business together under a common name. It’s quick to set up: all you need is a partnership agreement (highly recommended) and registration with the Registraire des entreprises in Quebec. No separate tax return is required: each partner reports their share of the profits on their personal tax return, which keeps administrative burdens light and startup costs minimal.

There are two downsides. First, liability: the partners are liable jointly and severally operating debts, on their personal assets, including for the actions of another partner. Next, taxation: profits are taxed in the year they are earned, at each individual’s personal tax rate (up to approximately 53% in Quebec in 2026), even if they remain in the business, no carryforward is possible.

• Strengths: simple and inexpensive to set up, minimal administrative burden, and profit-sharing tailored to the articles of incorporation.
• Limitations: unlimited and joint personal liability; no tax deferral; business continuity is jeopardized by the departure or death of a partner.
• Who it’s for: a group of people starting a low-risk business, profits fully withdrawn to cover living expenses, or a project you want to test before investing in a formal business structure.

The real question isn’t “which one is better,” but “where are you at?” As soon as there’s business risk, profits that exceed your living expenses, or a potential resale, the corporation comes out on top: asset protection, an SME tax rate of about 12%, and tax deferral. The SENC remains a good option for starting a business with multiple partners, quickly and at low cost, as long as the business exposure remains low.

• Choose a corporation if your profits exceed your living expenses, if your industry involves risk (lawsuits, debt, major contracts), or if you plan to sell the business someday: tax deferral, limited liability, and capital gains exemption all work in your favour.
• Choose the SENC if you’re starting a low-risk business with two or more partners, you’re withdrawing all profits to cover your living expenses, and you want a simple, low-cost structure backed by a solid articles of incorporation.
• Choose the two-step approach if you’re testing the market: start with a SENC, then switch to a corporation via a tax rollover when profits or risk increase.

In terms of accounting fees, a corporation is more expensive to maintain than a SENC (financial statements, T2, and CO-17). The Bankeo Fee Barometer estimates the median at around $3,000 per year, ranging from $500 to $6,000 depending on the industry (2024-2026 data based on 1,248 real-world cases).

Does a SENC protect my personal assets?

No. In a SENC, each partner is personally liable for the business’s debts with their personal assets, and this liability is joint and several: a creditor can demand full payment of a debt from a single partner, even if the debt was incurred by another. Your home, savings, and investments are at risk. If your business involves risk, a corporation offers protection that a SENC does not provide.

Can a SENC be converted into a corporation later on?

Yes, and this is a common path: you start as an SENC, then incorporate when profits or risk warrant it. A tax rollover (Section 85) allows you to transfer assets to the new corporation without triggering immediate tax liability. The timing of the transition is carefully calculated: a vetted accountant compares the taxes paid under each structure and plans the transition with you.

How much does it cost to form a corporation in 2026?

Expect to pay $200 for online federal incorporation, or a few hundred dollars for provincial incorporation (fees indexed annually), plus the fees of the professional who drafts the articles of incorporation and sets up the corporate book. A SENC is less expensive to set up initially: registration with the Registraire des entreprises and, ideally, a partnership agreement drafted by a lawyer.

What is the tax rate for a corporation in Quebec in 2026?

For an SME eligible for the SME deduction, the combined tax rate is approximately 12.2% (9% federal, 3.2% Quebec) on the first $500,000 of active income, subject to eligibility criteria, including paid hours. Above that threshold, the general combined tax rate rises to 26.5%. In a SENC, each partner is taxed at their personal rate, up to approximately 53%.

Does an SENC have to register for the GST and QST?

Yes, as soon as its taxable sales exceed $30,000 over four consecutive calendar quarters (end of small supplier status). Registration is done in the name of the SENC itself, not the partners, and the business then collects the 5% GST and the 9.975% QST. The same rule applies to a corporation.
