Salary wins because it is the deduction that survives
For a personal services business, salary is not one of two reasonable ways to pay the owner; it is the mechanism that keeps the corporation's tax bill near zero. A PSB may deduct salary, wages and benefits paid to the incorporated employee and very little else, so profit that leaves as salary is taxed once, on your personal return, at your marginal rate. Profit that stays in the corporation is taxed at roughly 44.5 per cent, and profit that leaves as a dividend is taxed at that corporate rate first and then again in your hands. Only one of those three paths is not a penalty.
The usual argument for keeping profit inside a corporation is deferral: the gap between the 12.2 per cent small business rate and your personal rate is capital you can invest until the money comes out. A PSB has no such gap: its corporate rate is within a few points of the top personal rate, so there is nothing to defer and nothing to protect by leaving money in. The instinct to retain, which is correct for most owner-managed corporations, is wrong here, and the plan is to pay it out. The reasons a corporation ends up with the label, and the four tests behind it, are in what is a personal services business; this page starts from the label and answers the payment question.
Salary also has a defensive value that dividends lack. If your PSB status is uncertain rather than settled, paying salary now protects you in both worlds: if CRA later finds the corporation was a PSB, the reassessed years have little income left to tax; if it was not, you have paid the same total tax you would have as a salaried owner of an ordinary corporation, having given up only a deferral you might not have been entitled to. That asymmetry is why we move uncertain files to salary first and argue about the facts second.
Bonusing out the profit before year-end, and the 180-day rule
You do not have to guess the year's profit in January; you can pay a base salary through the year and clear the remainder with a bonus declared at year-end. The bonus is accrued in the corporation's books as at the fiscal year-end and deducted in that year, provided it is actually paid within 180 days after the year-end. Miss the 180 days and the deduction moves to the year of payment, which for a PSB means a year of profit taxed at the corporate rate that could have been avoided. We diarize the deadline the day the year-end closes.
The mechanics are simple but unforgiving. The bonus is approved by a resolution dated on or before year-end, the amount is set once the year's numbers are known, and when it is paid it runs through payroll with source deductions withheld and remitted like any other pay. The bonus is your income in the calendar year you receive it, not the year the corporation deducted it, which creates a legitimate timing lever: where the 180-day window crosses December 31, which it does for a December year-end and for most year-ends in the second half of the calendar year, the corporation deducts the bonus in one fiscal year and you report it in the next calendar year. A year-end in the first half of the year usually has no such spread, because the 180 days expire before December.
Two cautions. The bonus must be reasonable for the work you performed, which for the incorporated employee who generated all of the revenue is rarely a problem but is worth a sentence in the resolution. And the cash has to exist; a bonus accrued against profit that was already spent on denied overhead cannot be paid, which is why the salary plan and the expense plan in what expenses a personal services business can still deduct have to be built together.
Payroll mechanics: T4, CPP and remittances
Salary only counts if it is paid as salary, which means a payroll account, withholdings and remittances, not a transfer labelled salary in the bank memo. The corporation registers a payroll program account with CRA, calculates income tax and CPP on each payment, remits the withheld amounts plus its own share of CPP by the due date for its remitter type, and files T4 slips and a T4 Summary by the end of February for the prior calendar year. EI premiums do not apply to you if you control more than 40 per cent of the corporation's voting shares, because that employment is not insurable, so the corporation neither deducts nor pays EI on your salary.
CPP is the cost people notice. Both the employee and employer contributions come out of what would otherwise be your money, and the combined amount is the price of building CPP entitlement, discussed below. Remittance discipline is the other cost: late or short remittances attract penalties quickly, and a one-person corporation paying itself irregularly is the classic late remitter. Setting a fixed monthly salary and topping up with the year-end bonus keeps the remittance calendar predictable; the traps are covered in how to prevent payroll remittance surprises.
Keep the paper consistent. The T4 total should reconcile to the salary and bonus deducted on the corporate return, the payroll remittances should reconcile to the T4 Summary, and the bonus resolution should match the accrual in the financial statements. A PSB reassessment reads all three together, and salary the auditor cannot trace through payroll is salary the auditor may not allow.
The dividend trap when the income already bore PSB tax
A dividend from a personal services business is the most expensive way to get money out of any Canadian corporation, and the reason is arithmetic rather than policy. Dividends are not deductible, so the profit they come from has already been taxed at roughly 44.5 per cent. The dividend is then taxed on your personal return with a gross-up and credit that were designed to compensate for corporate tax at ordinary rates, not at the PSB rate, so the credit falls well short of the corporate tax actually paid. The combined burden lands above the top personal rate, meaning you keep less than an employee earning the same amount would have kept after withholdings.
| Factor | Ordinary CCPC owner | Personal services business owner |
|---|---|---|
| Corporate deduction for what you pay yourself | Salary deductible; dividends not, but the corporate rate is low | Salary deductible; dividends come from profit taxed first at roughly 44.5 per cent |
| Deferral from retaining profit | Real, roughly 40 points on the first 500,000 dollars | None; the corporate rate nearly matches the top personal rate |
| Does the dividend credit match the corporate tax paid? | Approximately, by design | No; the credit assumes ordinary corporate rates |
| RRSP room and CPP | A reason to include some salary in the mix | A side benefit of a route you are taking anyway |
| Income splitting with family | Limited by TOSI; salary for real work still works | Same limits; dividends to family are taxed at top rates unless an exclusion applies |
| The decision each year | A genuine mix, re-set annually | Salary, with the only questions being how much and when |
The trap has a family version. Owners sometimes hope to pay dividends to a spouse or adult child to spread the PSB income across lower brackets, and the tax on split income rules generally tax those dividends at the top rate unless the family member genuinely works in the business or another narrow exclusion applies. For a one-person services corporation the exclusions rarely fit, and even where one does, the dividend still has to come out of profit taxed at the PSB rate first. A family member who actually does work can be paid a reasonable salary for it, which is deductible; that is the one splitting route that survives, and it survives only on real hours.
RRSP room and CPP: the side benefits of being forced onto salary
Salary is the route a PSB takes anyway, so the benefits that usually have to be weighed against deferral come free. Salary is earned income for RRSP purposes, generating contribution room of 18 per cent of the prior year's earned income up to the annual dollar limit, and dividends generate none. For an owner who has been paying dividends for years and has no room, a switch to salary rebuilds it from the next year, and an RRSP contribution is one of the few ways a PSB owner can still shelter income from tax, because it is a personal deduction that does not depend on the corporation's rules.
CPP works the same way. Contributions on salary build pensionable earnings and a CPP retirement pension, along with disability and survivor coverage, none of which dividends provide. The employer and employee contributions together are a real cost, and a PSB pays both halves out of what is effectively the owner's money, but the alternative for a PSB was never a cheaper dividend; it was a dividend that cost more. Seen that way, the CPP and RRSP effects are the consolation prize of a structure that is otherwise doing little for you, and for owners planning retirement they are not a small one.
Reported salary also helps with the mortgage and lending questions that dividend-paid owners struggle with, since lenders read T4 income more easily than a chain of corporate statements. It is a minor point beside the tax, but it is a point in the same direction.
Retained earnings from earlier years, and how this differs from the ordinary decision
If the corporation already holds retained earnings from earlier years, the right treatment depends on which tax those earnings actually bore. Earnings from years that are closed and were taxed at the small business rate can be paid out as dividends on the ordinary basis; the low corporate tax was real, the dividend credit roughly matches it, and there is no reason to rush them out. Earnings from years CRA has reassessed at the PSB rate are the problem: the corporate tax is sunk, the dividend adds a second layer whenever it is paid, and the only levers left are timing, paying them out in years when your other income is low, and patience. There is no route that recovers the corporate tax already paid on them, and salary paid now does not reach back to those years, except that a large current-year salary that pushes the corporation into a loss can sometimes be carried back against earlier open years, which is a modelling exercise rather than a rule of thumb.
The ordinary salary-versus-dividends decision, worked through in salary versus dividends for Canadian business owners, is a genuine trade-off: deferral and simplicity on the dividend side, RRSP room, CPP and lender-friendly income on the salary side, re-set each year against your personal bracket and the corporation's cash needs. For a PSB the trade-off collapses, because the dividend side has no deferral to offer and carries a penalty instead. The only decisions left are how much salary, how much bonus, and when to pay it.
The facts that change the answer, in the order we check them:
- Whether the PSB label is settled or arguable: settled means salary to nil; arguable means salary as insurance while the facts are fixed.
- Your fiscal year-end: a year-end whose 180-day window crosses December 31 lets a bonus deducted in one corporate year be taxed to you in the next calendar year.
- Whether the corporation has any income the PSB rules do not touch: a second genuine business or investment income can be retained on ordinary terms.
- What the retained earnings actually bore: the small business rate in closed years, or the PSB rate on reassessment.
- Family members who genuinely work in the business: reasonable salary for real hours is deductible; dividends to them are mostly not worth paying.
- Whether the facts will change: if next year's engagement is genuinely independent, the retention question reopens on ordinary terms.
We run PSB compensation as part of the payroll and year-end work inside End-to-End Accounting: the monthly salary, the bonus resolution, the 180-day diary and the T4s, all reconciled to the corporate return so that the deduction holds. If your corporation is paying you dividends and one client pays most of your invoices, a free 15-minute discovery call is the fastest way to find out whether you are standing in the trap.
