The Idea Behind It All
Canadian tax policy tries to make the corporation invisible. If integration worked perfectly, a dollar earned through your company and paid out to you would cost exactly what a dollar earned directly would.
It doesn’t work perfectly — there are modest advantages and disadvantages depending on province and income type — but it works well enough that you should stop looking for a structure that makes income tax-free. There isn’t one. What a corporation genuinely gives you is control over timing, and timing is worth a great deal.
Money left in the corporation has been taxed at roughly 11%. The remaining 89 cents can be invested, used to fund growth, or held against a lean year. Had you earned the same income personally at a 45% marginal rate, you would be investing 55 cents. Over a decade that difference compounds substantially — and you choose which year the personal tax is triggered.
Key Takeaways
- Canada’s system aims at integration — earning through a corporation and paying it out should cost roughly the same as earning it personally. The advantage is timing, not rate.
- Salary builds RRSP room and CPP entitlement; dividends avoid CPP but build neither. Most owners should take some of each.
- A shareholder loan not repaid by the end of the following fiscal year becomes personal income in full.
- TOSI ended most casual income splitting in 2018. Paying a spouse or adult child requires meeting a specific exclusion, not just issuing shares.
- The lifetime capital gains exemption is $1,275,000 for 2026 — but qualifying for it requires conditions met over the 24 months before a sale.
Salary versus Dividends
| Salary | Dividend | |
|---|---|---|
| Corporate deduction | Yes — reduces corporate tax | No — paid from after-tax income |
| CPP | Both halves, ~$9,300 at the ceiling | None |
| RRSP room | Yes — 18% of earned income to the annual limit | None |
| Payroll administration | Source deductions, T4, remittances | T5 slip, director’s resolution |
| Personal tax | Ordinary rates | Gross-up and dividend tax credit |
| Supports a mortgage application | Readily | Often with more difficulty |
Dividends come in two flavours. Non-eligible dividends are paid from income that was taxed at the small business rate and carry a smaller gross-up and credit. Eligible dividends come from income taxed at the general rate, tracked in the GRIP account, and are taxed more favourably in your hands. Most owner-managers of small CCPCs are paying non-eligible dividends.
Choosing Your Mix
There is no universal answer, but there are reliable considerations.
Take enough salary to maximise RRSP room if you intend to use it. RRSP room accrues at 18% of earned income, and dividends generate none. An owner who takes only dividends for a decade arrives at retirement with no registered room and no CPP.
CPP is a genuine choice, not simply a cost. The combined 11.90% feels like pure expense, but it buys an indexed, government-backed lifetime pension. Owners who dismiss it should be doing so because they have a deliberate alternative plan, not because the deduction is annoying.
Dividends are more flexible. They can be declared after year end when the numbers are known, adjusted to the actual result, and don’t require monthly remittances. For businesses with volatile income this is a real administrative advantage.
Watch the bracket. Where a large one-off dividend would push you into a higher bracket, splitting it across two calendar years is often worth more than any structural planning.
Shareholder Loans
If you take money from the corporation that isn’t salary, dividend, or repayment of something the company owes you, it is a loan — and section 15(2) of the Income Tax Act governs it.
The rule: a loan to a shareholder must be repaid by the end of the corporation’s fiscal year following the one in which it was made, or the entire amount is included in the shareholder’s income for the year it was received. Not the interest. The whole balance.
Repaying just before year end and redrawing immediately after is specifically anticipated — the rules look for a series of loans and repayments and will treat them as continuous. There are narrow exceptions, including loans for a home purchase or to acquire shares of the employer, but they carry their own conditions including a bona fide repayment schedule.
While a loan is outstanding you also have a taxable interest benefit, calculated at the CRA’s prescribed rate, unless you pay the corporation interest at that rate within 30 days of year end.
The account that runs the wrong way
Many owners have a shareholder loan account that is genuinely in their favour — they lent the company startup money, or paid business expenses personally. Drawing that down is tax-free, because you are being repaid your own capital. The problem is that almost nobody tracks the balance properly. Keep it clean: it is the cheapest money you will ever take out of your company, and it is worthless if you cannot prove it.
Paying Family Members
Paying a spouse or adult child a salary is legitimate where the work is real and the pay is reasonable for that work. Both conditions matter. The CRA will disallow a $60,000 salary for a few hours of administration, and it will look closely where the amount lands conveniently at the top of a low bracket.
Document as you would for any employee: a job description, time records, pay at a defensible market rate, actual payments into their own bank account, proper source deductions and a T4. A salary that exists only as a year-end journal entry is the easiest adjustment an auditor will make all week.
TOSI
The tax on split income rules, substantially expanded in 2018, are the reason the old approach of issuing shares to a spouse and paying dividends no longer works by default. Where TOSI applies, the dividend is taxed at the highest marginal rate regardless of the recipient’s own income, eliminating the benefit entirely.
TOSI is the default for dividends paid to a related individual, and you must fit within an exclusion to avoid it. The main ones:
- Excluded business — the individual worked in the business an average of 20 hours a week during the year, or in any five previous years.
- Age 25 and owning 10% or more of votes and value, where the business is not a professional corporation and earns less than 90% of its income from services.
- Age 65 owner — amounts that would have been excluded for the owner can be paid to their spouse, a deliberate retirement-splitting provision.
- Reasonable return, judged on labour and capital contributed and risk assumed — narrower for those aged 18 to 24.
These are technical tests with real consequences for getting them wrong. Do not restructure share ownership on the strength of a summary like this one.
Where to Put Excess Cash
Profit accumulating in the corporation has to go somewhere, and the options interact with the passive income rules described in the T2 corporate tax guide.
Leave it and invest inside the corporation. You are investing pre-tax dollars, which is powerful, but investment income is taxed at roughly 50% corporately, and once it passes $50,000 a year it starts grinding down your small business limit on operating profit.
Pay salary and contribute to an RRSP. Straightforward, creates room, and moves money into a fully tax-sheltered environment. Costs CPP on the way out.
Pay dividends and fund a TFSA. No CPP, and TFSA growth is genuinely tax-free rather than deferred.
An individual pension plan may allow larger deductible contributions than an RRSP for older, higher-earning owners, at the cost of complexity and actuarial fees.
Most owners end up with a combination, and the right one shifts as the corporation’s investment portfolio grows toward the $50,000 threshold.
The Lifetime Capital Gains Exemption
On a sale of qualifying small business corporation shares, the LCGE shelters a lifetime total of $1,275,000 for 2026 in capital gains — indexed annually. For a business owner this is the largest single tax benefit available in the Act, and it applies per individual, which is why family ownership structures can multiply it.
Qualifying is the hard part, and it is tested against conditions in the period before the sale:
- At the time of sale, 90% or more of the fair market value of the corporation’s assets must be used in an active business carried on primarily in Canada.
- Throughout the 24 months before the sale, more than 50% of asset value must have met that active business test.
- The shares must not have been owned by anyone other than you or a related person during those 24 months.
The 90% test is what catches people. A corporation holding surplus cash, a portfolio, or a building not used in the business can fail it on the day of sale — and the fix, moving those assets out, is a transaction with its own tax consequences that needs to happen well in advance. This is the clearest example in Canadian tax of planning that must start years before the event.
Planning an Exit
Buyers usually want to buy assets; sellers usually want to sell shares. A share sale gives the vendor access to the LCGE and a clean exit; an asset sale gives the purchaser a stepped-up cost base and leaves known liabilities behind. The gap between those preferences is negotiated in price.
An asset sale also leaves cash inside your corporation, which must then be extracted — potentially triggering a second layer of tax, though the capital dividend account can move part of it out tax-free.
The practical advice is unglamorous: start three years out — the tax and bookkeeping side of selling a business covers the sequence. Purify the balance sheet so the 90% test is met, get financial statements into a state a buyer’s advisers will accept without discounting, document that the business runs without you, and resolve any shareholder loan balances. Businesses sold on six weeks’ notice are sold at a discount, and much of that discount is tax that could have been planned away.
