The 11.9% CPP surprise
When you were an employee, CPP came off your cheque and your boss quietly matched it. Self-employed, you are both — so you pay both halves. This is the single biggest shock in a contractor's first solo tax bill.

Why the first year hurts
Employees never really see CPP. A bit comes off each cheque, the employer matches it behind the scenes, and it's invisible. The day you go out on your own, that whole thing lands on you at once — both halves, 11.9% in 2026 (see the CRA's CPP contribution rates) — and it shows up as one big line in your balance owing.
At the 2026 maximum, that's about $8,461 in base CPP alone, before a single dollar of income tax — plus up to $832 more in CPP2 once your earnings pass $74,600, per the CRA's CPP contribution rates. For a lot of first-year contractors, the CPP is bigger than they expected the entire bill to be.
The part that softens it
You do get relief: a deduction for the employer half and a credit for the employee half. It lowers your income tax — but it does not reduce the cash you have to hand the CRA. The full contribution is still due. Relief on the tax side, not the cash side.
How to not get caught
This is the real reason the "set aside 25–30%" rule is as high as it is — pure income tax would be lower; CPP is what pushes the number up. The good news: the calculator for your province already builds the full self-employed CPP into your total and your monthly set-aside, so if you follow that figure, the CPP is already covered. Nobody who plans for it gets surprised by it.
This doubled CPP is also the whole reason a self-employed dollar is worth less than a salaried one. If you're weighing a T4 job against going out on your own, the employee vs self-employed calculator shows exactly what that second CPP half costs you — and how much self-employment income it takes to match a salary.
Common questions
How much CPP does a self-employed person pay in 2026?
Self-employed contributors pay 11.9% of pensionable earnings (both the employee and employer halves) up to the year's maximum pensionable earnings of $74,600, after a $3,500 basic exemption. That's a maximum base contribution of about $8,460.90 for 2026. On top of that, CPP2 applies at 8% on earnings between $74,600 and $85,000, up to about $832 more.
Why do I pay double the CPP I used to?
As an employee you paid one half (about 5.95%) and your employer paid the matching half. Self-employed, there is no employer — you are it — so you pay both halves. Your total percentage doesn't change versus what was really being paid on your behalf; it's just that all of it now visibly comes out of your pocket.
Is any of the CPP deductible?
Yes. You get an income tax deduction for the 'employer' half of your CPP, and a tax credit for the 'employee' half. It softens the blow, but it doesn't remove the cash requirement — you still have to pay the full amount to the CRA, usually as part of your balance owing or through instalments.
How do I avoid getting blindsided by it?
Budget for it from day one. When people say 'set aside 25–30% for taxes,' the CPP is a big part of why that number is that high — income tax alone would be lower. This calculator includes the full self-employed CPP in the total, so the monthly set-aside figure it gives you already accounts for it.
Can I opt out of CPP if I'm self-employed?
No — for most self-employed people CPP contributions are mandatory once your net self-employment earnings pass the $3,500 basic exemption. You can't opt out the way you might imagine. (Once you're 65+ and collecting CPP there are limited election options, but for a working-age contractor it's required.)
What is CPP2 and do I have to pay it?
CPP2 is the second earnings tier added by the CPP enhancement. In 2026 it applies at 8% (both halves, self-employed) on earnings between $74,600 and $85,000, up to about $832. If your net income is under $74,600 you don't pay any CPP2; above it, you pay it on the slice in that band.
