A qualifying corporation pays roughly 12.2% tax on its first $500,000 of active income in Québec, against a personal rate that can exceed 50%. Deferral, income splitting and the capital gains deduction complete the picture.
Incorporating is often sold as a way “to pay less tax”, an appealing phrase but an imprecise one. A business corporation does not make tax disappear: it changes when you pay it, at what rate, and how much room you have to manoeuvre. Used well, those three levers add up to substantial savings. Misunderstood, they disappoint. Here is the straight version.
A markedly lower entry rate
The active business income of a qualifying corporation benefits, on its first $500,000, from the small business deduction. The resulting combined federal and Québec rate is several times lower than an individual’s top marginal rate. One important Québec wrinkle: access to the reduced provincial rate depends partly on the corporation’s volume of paid hours, which can limit the advantage for very small structures with no employees. The precise calculation belongs to your accountant; the order of magnitude remains striking.
Deferral: paying later, on your own terms
The central advantage is not the rate but control of the calendar. In a corporation you decide how much you take out, as salary or as dividends, and how much stays in the business. What stays has borne only corporate tax; personal tax arrives only on withdrawal, at a moment you choose. An entrepreneur who earns well can therefore smooth income over time, take more in lean years and less in good ones, and in the meantime put to work sums that, in a sole proprietorship, would have been cut down immediately by the marginal rate.
Flexible remuneration
Salary, dividends, or a mix of the two: each has its effects on payroll contributions, Québec Pension Plan entitlements, RRSP room and instalments. A corporation also allows certain family strategies, although the rules on split income have considerably narrowed splitting with relatives who do not actively participate in the business. Here too, caution and professional advice: the flexibility is real, but it operates within limits that have become strict.
The choice between salary and dividend comes round every year. Here is what separates them, without the figures, which depend on your situation.
| Salaire | Dividende | |
|---|---|---|
| Deductible for the corporation | Yes | No |
| Payroll contributions | Yes | No |
| Québec Pension Plan entitlements | Generates entitlements | Generates none |
| Espace REER | Creates room | Creates none |
| Source deductions | To be withheld and remitted | No withholding of that kind |
| A decision to document | Remuneration resolution | A directors’ resolution |
| Régularité | Predictable, periodic | Adjustable to available cash |
Your accountant runs the numbers; we secure the legal form of the decisions.
On a sale: the capital gains deduction
This is the advantage least thought about at the start and the one that weighs most at the end. The sale of qualified small business corporation shares can benefit from the lifetime capital gains exemption, which shelters from tax a gain exceeding a million dollars per person, according to the indexed limit in force. The conditions of eligibility, the nature of the corporation’s assets and the holding period, are prepared years in advance. A self-employed worker selling a client list has nothing comparable. For anyone building a business to sell one day, this alone can justify incorporating.
The last word
These advantages share one condition: profits that exceed what you need to live on. Incorporating does not create wealth, it optimizes the wealth that already exists. If your activity has reached that point, the business corporation is probably the most profitable tool the law puts at your disposal; we set it up in a few days, and your accountant will run its machinery year after year.
The advantages that exist only if you prepare them
Part of the above does not trigger automatically on the day you need it. The capital gains deduction is the most expensive illustration: it requires the corporation to meet certain conditions on the nature of its assets and on the period the shares have been held. A corporation that has, over the years, built up substantial cash, investments or real estate unconnected to the operating business can stop meeting those criteria without anyone noticing.
The consequence lands at the worst moment: an offer to purchase arrives, and it turns out the shares do not qualify, or will not until a holding period has run from a clean-up still to be done. That clean-up, called purification, is a routine operation, but it is planned in advance and not in the middle of a negotiation.
The practical conclusion holds for any entrepreneur contemplating a sale one day, however distant: have the eligibility of your shares checked periodically rather than assuming it. A review every two or three years with your accountant is generally enough.
Investment income, the blind spot of accumulation
Leaving profits in the corporation is the heart of the deferral strategy. Those sums end up being invested, though, and the income they generate follows rules different from those governing business income.
Two effects are worth knowing. First, investment income earned in a corporation does not benefit from the small business rate and bears markedly heavier tax, partly recoverable when dividends are paid, through mechanisms your accountant understands. Second, and this is the point few entrepreneurs anticipate, beyond a certain level of investment income the corporation’s access to the reduced rate on its business income is progressively ground down.
In other words, the accumulation that made incorporating worthwhile can, past a certain volume, erode the very advantage that justified it. That is not a reason not to accumulate; it is a reason to watch the threshold and to consider, when the time comes, other structures for accumulation. Our article on corporate taxation addresses the role a holding corporation can play in that situation.
Taking money out: the reflexes that cost you
The corporation’s tax leverage rests on a clear boundary between its patrimony and yours. The most frequent mistakes consist precisely in blurring it.
Paying personal expenses out of the corporate account does not make them deductible and generally creates a taxable benefit in your hands, often together with a denial of the deduction for the corporation. You therefore pay twice for having tried to pay less.
Shareholder advances are another recurring source of reassessments. Taking money out of your corporation and booking it as a loan is possible, but regulated: an amount not repaid within the period the law provides can be added to your income, and a balance that drags on year after year inevitably attracts attention. The direction of the advance matters too: money you lent your corporation can be repaid to you tax-free, provided the account is properly kept and kept separate from the rest.
The undocumented dividend closes the list. A payment entered after the fact by the accountant, with no résolution authorizing it, is an anomaly that is easy to spot and hard to justify. Legal form is not separate from tax: it is what tax rests on.
Frequently asked questions
Does incorporating really mean paying less tax?
It does not make tax disappear: it changes when you pay it, at what rate, and with how much room to manoeuvre. The advantage only materializes if you earn more than you need to live on, since it is the surplus left in the corporation that is taxed only at the corporate rate.
What is the capital gains deduction?
It is a mechanism that can shelter from tax a substantial part of the gain realized on the sale of qualified small business corporation shares. The conditions of eligibility, tied to the corporation’s assets and to the holding period, are prepared years in advance.
Can I take money out of my corporation as I please?
No. Paying personal expenses out of the corporate account generally creates a taxable benefit, an advance not repaid within the prescribed period can be added to your income, and a dividend paid without an authorizing resolution is an anomaly that is easy to spot.
