Should you incorporate in Québec? 2026 guide

Short answer Incorporating generally pays off when your profit is well above what you need to live on and you can leave the surplus in the company for several years. For a solo owner in Québec that usually starts around $120,000 to $150,000 of profit. Below that, or if you take everything out each year, the extra costs and Québec’s 20.5% rate for small solo corporations usually cancel the benefit.

“Should I incorporate?” is one of the first questions self-employed people in Québec ask us, usually once revenue starts climbing. The honest answer depends less on revenue than on how much profit you can leave in the business. A corporation mostly lets you defer tax, not avoid it. Below we explain what changes, the numbers at several profit levels, what it really costs, what limited liability does and doesn’t do, the Québec rules that catch people off guard, and how to incorporate step by step.

What changes when you go from sole proprietor to corporation?

	Sole proprietor (self-employed)	Corporation (société par actions)
Legal status	You and the business are the same person	A separate legal person that you own through shares
Tax on profit	All profit taxed on your personal return, up to 53.31%	12.2% or 20.5% on the first $500,000 while profit stays in the company; personal tax when you take it out
Returns	T1 and TP-1 with business statements (T2125 and TP-80)	T2 and CO-17 for the corporation, plus your own T1 and TP-1
QPP	Both halves on your net business income	Only on the salary you take, none on dividends
Losses	Reduce your other income	Stay in the corporation
Registry	REQ registration only if required (for example a business name other than your own): $41, then $41 a year	Incorporation $397, then an annual updating declaration ($106)
Liability	Unlimited	Generally limited, with important exceptions
Selling the business	You sell assets	You can sell shares and may use the lifetime capital gains exemption ($1,275,000 in 2026)

If you are still a sole proprietor, our self-employed tax guide covers how you are taxed today.

How does the tax deferral actually work?

Take $10,000 of extra profit for a sole proprietor whose income is already about $150,000. At a combined marginal rate of 47.46%, they keep $5,254. In a corporation that pays 20.5%, $7,950 stays in the company after tax, or $8,780 at 12.2%. That difference, $2,696 or $3,526, is tax deferred: you pay personal tax on it when the corporation pays it to you as a dividend.

If you take everything out in the same year, the deferral disappears and the total tax ends up about the same, or higher. The real gains come from:

Time: the deferred tax can be invested or used in the business for years.
Lower-income years: taking dividends later, during a sabbatical, a slow year or retirement, at lower personal rates.
Selling the shares: the lifetime capital gains exemption, if the shares qualify.
Family planning: in limited cases allowed by the TOSI rules.

Keep in mind that investment income earned inside a CCPC is taxed at about 50.17% in Québec, with 30.67 points refundable when dividends are paid. Passive income over $50,000 a year also starts to reduce the corporation’s small business limit.

At what profit does incorporating start to pay off?

Here is an illustrative estimate for a solo owner who needs about $75,000 of salary to live on and leaves the rest in the corporation. Assumptions: single, living in Québec, no other income, 2026 federal and Québec rates, business income under $500,000, no EI on the owner’s salary, HSF at 1.65%. As a sole proprietor, the owner pays both halves of QPP and the self-employed QPIP rate (0.764%). The corporation pays 20.5% because one person can’t meet Québec’s 5,500-hour test. The last column shows the deferral if the corporation qualified for 12.2%. Extra annual costs are not deducted.

Profit before owner pay	Sole proprietor: tax, QPP and QPIP	Corporation: tax and contributions this year	Left in the corporation after tax	Tax deferred this year (20.5%)	Tax deferred at 12.2%
$80,000	$25,849	$25,919	$0	None	None
$100,000	$33,647	$30,321	$14,923	$3,326	$4,883
$120,000	$41,263	$34,421	$30,823	$6,842	$10,060
$150,000	$55,287	$40,571	$54,673	$14,716	$20,423
$200,000	$79,352	$50,821	$94,423	$28,531	$38,389
$300,000	$130,651	$71,321	$173,923	$59,330	$77,488

How to read the table

Up to about $80,000: the owner needs all the profit, so nothing stays in the corporation and there is nothing to defer. Incorporating only adds costs.
Around $100,000: about $3,300 is deferred, roughly what the extra accounting and filings cost. It is a wash.
From about $120,000 to $150,000: the deferral ($6,800 to $14,700 a year) clearly exceeds the costs, as long as you really leave the money in the company.
Above $200,000: the deferral becomes significant.

Two checks matter. First, if the owner at $150,000 took all the profit out in the same year (salary plus dividends), the total would be about $58,900 instead of $55,300 as a sole proprietor: about $3,600 more tax, plus fees. Incorporating only to take everything out doesn’t pay in Québec at 20.5%. Second, if the $54,673 left in the corporation is paid out later as a dividend in a year with no other income, the personal tax on it is roughly $5,500 at 2026 rates (about $6,000 with the dividend credit announced for 2027). That is where the deferral turns into real savings. To decide how to pay yourself once incorporated, see our salary vs dividends guide.

What does a corporation cost to set up and run?

Government fee	Québec corporation	Federal corporation
Incorporation	$397 at the Registraire des entreprises ($595.50 priority)	$200 online at Corporations Canada, plus registration with the Registraire des entreprises (its fee schedule lists $397 for a corporation constituted outside Québec)
Name	Numbered company, or optional name reservation ($27)	Numbered company, or a NUANS name search report
Annual registry filings	Annual updating declaration: $106	Federal annual return ($12 online) plus the Québec annual updating declaration

In both cases, add:

Legal setup: bylaws, share issuance, minute book, register of ultimate beneficiaries, and a shareholder agreement if you have partners. The cost depends on your lawyer or notary.
Corporate returns (T2 and CO-17): with us, from $1,200 a year, or $900 for Growth and Scale bookkeeping clients.
Payroll, if you take a salary: with us, $75 a month for 1 to 5 employees.
Separate bookkeeping: with us, plans from $350 a month.

As a rough estimate, plan for about $2,500 to $4,500 a year more than as a sole proprietor, depending on your volume and legal upkeep. Your corporation also needs its own bank account and books. Mixing personal and business spending creates shareholder loan and taxable benefit problems. See our bookkeeping and corporate tax services and pricing.

Does incorporating protect my personal assets?

Partly. A corporation’s debts are generally its own, and shareholders risk only what they invested. In practice:

Banks, landlords and some suppliers usually ask a young corporation’s owner for a personal guarantee.
Directors can be personally liable for unpaid source deductions, unremitted GST and QST, and certain unpaid employee wages.
You remain personally responsible for your own professional errors. Insurance does more than incorporation here.

Limited liability is a real benefit when the business signs contracts, has employees or carries risk, but it is rarely a reason on its own to incorporate.

Should I incorporate in Québec or federally?

Québec incorporation: one registry, one annual declaration, lower total cost. Usually the better choice if you operate mainly in Québec.
Federal incorporation: your name is protected across Canada and it is easier to operate in several provinces, but you must also register with the Registraire des entreprises to do business in Québec, so you have two registries and two annual filings. Federal corporations also report individuals with significant control to Corporations Canada.

Tax is the same either way. The corporation pays federal and Québec tax based on where it earns income, not where it was incorporated.

What is the Québec 5,500-hour rule and does it apply to me?

The federal small business rate (9%) is available to almost every CCPC. The Québec rate (3.2%) requires that the corporation’s employees were paid for at least 5,500 hours in the year, or, with associated corporations, in the previous year. It is reduced between 5,500 and 5,000 hours and is nil below 5,000. Hours count up to 40 per week per person. Corporations in the primary and manufacturing sectors can qualify through a separate activity test.

A solo consultant counts at most about 2,080 hours, so their corporation pays 20.5% instead of 12.2%. That is why our table uses 20.5%, and why incorporating pays later in Québec than calculators built for other provinces suggest. In April 2026 Québec announced a cut of its small business rate to 2.2% for taxation years beginning after April 29, 2026. It doesn’t change the hours test. It comes with a smaller Québec credit on non-eligible dividends from 2027, which also applies to owners of corporations at 20.5%. It was not passed into law before the October 2026 election, so the new government has to confirm it.

I work for one main client. Can I incorporate?

You can, but be careful. If, without the corporation, you would reasonably be considered an employee of your client, the corporation can be treated as a personal services business. It then loses the small business deduction, pays the full corporate rates plus an extra 5% federal tax, and can deduct very few expenses. Several clients, your own tools and real business risk reduce this exposure. We review the facts before you incorporate.

Can professionals incorporate in Québec?

Members of a Québec professional order (accountants, engineers, lawyers, physicians and others) can practise through a corporation only if their order’s regulations allow it, and under its conditions on ownership, directors and liability insurance. Your personal professional liability stays. The 5,500-hour rule applies too, so a professional corporation with no staff also generally pays 20.5% in Québec.

What about the lifetime capital gains exemption?

When you sell shares of a qualified small business corporation, up to $1,275,000 of capital gains can be exempt in 2026. The main tests: at the time of sale, all or substantially all (90% or more) of the corporation’s assets are used in an active business mainly in Canada; over the previous 24 months, more than 50% of its assets were; and the shares were held by you or a related person for those 24 months. A sole proprietor can’t use this exemption on a sale of business assets. If a sale is in your plans, incorporate early enough and keep the corporation free of excess investments.

Can I split income with my family through a corporation?

Much less than before 2018. Dividends to family members who don’t work in the business are generally subject to the tax on split income (TOSI) at the top rate. Exclusions exist: a family member who works in the business an average of 20 hours a week (now or in any five previous years), a shareholder aged 25 or older with at least 10% of the votes and value of a corporation that is not a professional corporation and earns less than 90% of its income from services, or your spouse once you are 65. A reasonable salary for real work remains possible.

When should you not incorporate?

You need nearly all your profit to live on, so nothing stays in the company.
Your profit is under about $100,000 and you work alone.
You expect losses in the first years. As a sole proprietor, they reduce your other income.
You work like an employee for a single client (personal services business risk).
You plan to take everything out each year anyway.
You don’t want separate books, a minute book and two extra returns a year.

You can incorporate later. Business assets can generally be transferred to a new corporation on a tax-deferred basis (a section 85 rollover, with the matching Québec election).

How do you incorporate a business in Québec, step by step?

Plan the structure with your accountant: who owns shares, which share classes, whether a holding company makes sense, and your year-end.
Choose a name or a number. A name must comply with Québec’s French-language rules. A numbered company is faster.
File the articles of incorporation online with the Registraire des entreprises and pay the fee. The corporation receives its Québec enterprise number (NEQ).
Organize the corporation: adopt bylaws, elect directors, issue shares, open the minute book and the registers, and declare the ultimate beneficiaries.
Open tax accounts: a CRA business number and corporate income tax account, registration for GST and QST with Revenu Québec if needed (see our GST/QST guide and GST/QST filing service), and payroll accounts with the CRA and Revenu Québec if you will take a salary (see payroll).
Move the business in: a corporate bank account, contracts and invoices in the corporation’s name, and a rollover of equipment or other assets where useful.
Set up separate bookkeeping from day one.
Stay compliant: T2 and CO-17 within six months of year-end, the annual updating declaration, annual minutes, and T4/RL-1 or T5/RL-3 slips by the end of February. Our tax deadlines guide lists them.

Frequently asked questions

At what profit should I incorporate in Québec?

There is no single number, but for a solo owner it generally starts to pay around $120,000 to $150,000 of profit, when you can leave a meaningful surplus in the company each year. Below about $100,000, the extra costs usually cancel the tax deferral.

Does incorporating reduce my taxes?

Mostly it defers tax on the profit you leave in the corporation. Permanent savings come from paying it out in lower-income years, the lifetime capital gains exemption on a sale and, in limited cases, family planning allowed by the TOSI rules.

How much does it cost to incorporate in Québec?

The Registraire des entreprises charges $397 to incorporate and $106 for each annual updating declaration. Add legal setup and yearly accounting; with us, corporate returns (T2 and CO-17) start at $1,200 a year.

Should I incorporate federally or in Québec?

If you operate mainly in Québec, a Québec corporation is usually simpler and cheaper because you deal with one registry. Federal incorporation protects your name across Canada but adds a second registry and annual filing. Tax is the same either way.

Does a corporation protect my house and savings?

Generally only partly. Lenders and landlords often require a personal guarantee, directors can be liable for unpaid source deductions and GST/QST, and your own professional errors stay personal.

Why is my small corporation taxed at 20.5% instead of 12.2%?

Québec gives its small business rate only to corporations with at least 5,500 paid hours (reduced between 5,500 and 5,000), unless they are in the primary or manufacturing sectors. A one-person corporation can’t reach that, so it pays 9% federal plus 11.5% Québec.

I have one main client. Is incorporating risky?

It can be. If you would be an employee of that client without the corporation, the CRA can treat it as a personal services business, which loses the small business rate, pays an extra 5% federal tax and can deduct very few expenses.

Can I incorporate my existing business later?

Yes. Business assets can generally be transferred to a new corporation on a tax-deferred basis with a section 85 rollover and the matching Québec election. We plan the timing with you.
