Commission Tax in Canada 2026: How Much You Actually Take Home

Is commission taxed higher than salary? (No)

This is the biggest myth in sales pay: commission is not taxed at a higher rate than salary. A dollar of commission and a dollar of salary are taxed at the exact same federal and provincial brackets, and the same CPP and EI rules apply.

On your T4, commissions show up in Box 42 — but that amount is already included in Box 14 (total employment income). It is shown separately only so the CRA can see how much of your pay was commission. It is not added on top of your income.

So why does your commission cheque feel like it gets hammered? Because of withholding, not the tax rate.

How much of your commission do you actually keep?

Here is the real math for an Ontario salesperson on a $50,000 base salary. The table shows how much of each commission you keep after federal tax, provincial tax, CPP and EI (2026):

So a big commission year nets you roughly two-thirds of the commission — not the half-or-less that a lump-sum cheque's withholding makes it look like.

Why your commission cheque looks so heavily taxed

When commission (or a bonus) is paid as a separate lump-sum cheque, the CRA tells employers to use the "bonus method" so they do not massively over-withhold. In short, it annualizes the payment: spread the commission across your pay periods, calculate the tax on your regular pay plus that slice, and withhold the difference.

The key point: withholding is only an estimate of your tax, not the final tax. Your real tax is always calculated on your total annual income when you file. CRA's own illustration shows a $5,000 payment withholding roughly $1,000 under the bonus method versus about $1,800 under the plain periodic method — but actual amounts vary by pay frequency, province and your regular pay.

Because commission is lumpy and can push you into a higher bracket, withholding often does not match your real tax:

• Over-withheld → you get a refund at filing.
• Under-withheld → you have a balance owing.

Neither is "extra tax" — it is just settling up. If you regularly come up short, ask your employer about Form TD1X, which can base your withholding on your estimated net annual commission.

Do you pay CPP and EI on commission?

Yes. For an employee, commission is pensionable and insurable exactly like salary, so CPP (plus CPP2 above the first ceiling) and EI are deducted up to the same annual maximums. Once you hit the yearly maximum, deductions stop for the rest of the year.

Employee (T4) vs. self-employed (T4A) — realtors, contractors, agents

The tax rate is the same either way. What changes is everything around it:

Many real estate agents are self-employed, so they typically owe a larger balance at filing (no tax withheld) and pay both halves of CPP. Insurance and financial commissions are often GST/HST-exempt — a separate wrinkle from the $30,000 rule.

Lower your tax: the commission-employee deduction (Line 22900)

This is the one real tax break unique to commission employees. With a signed Form T2200 from your employer, you can deduct employment expenses on Form T777 (Line 22900) that salaried employees cannot. To qualify, all of these must be true:

1. Your pay varies with sales volume or contracts (a fixed "commission" does not count);
2. Your contract requires you to pay your own expenses;
3. You normally work away from the employer's place of business;
4. You did not get a tax-free travel allowance.

What you can deduct that salaried employees cannot includes advertising and promotion, client meals and entertainment (50%), licences and liability insurance, and a portion of home insurance and property tax for a work-space at home.

The catch: except for interest and capital cost allowance on your vehicle, your total deductions cannot exceed the commission you earned that year — you cannot use sales expenses to create a loss. And a T2200 is necessary but not sufficient: each expense still has to genuinely qualify, be unreimbursed, and be receipted.

Same $80,000, different province

A salesperson earning $50,000 base + $30,000 commission = $80,000 keeps a different amount depending on where they live (2026 take-home):

General information for 2026, not tax advice. Commission tax rules (the bonus method, the four T2200 conditions, Line 22900) are stable year to year, but dollar thresholds like the CPP/EI ceilings change annually — confirm current figures with the CRA.
