How Much Tax to Set Aside When Self-Employed in Canada (2026): Your Number, Not a Flat 25%

The short version

For most self-employed Canadians in 2026, the right set-aside is somewhere between about 24% and 31% of your net self-employment income — and where you sit in that range depends on three things you can name in one breath. How much you earn. Which province you live in. And the fact that you pay both halves of CPP.

A flat "save 25–30%" is not wrong, exactly. It is a guess wearing a suit. At $50,000 in Ontario it is roughly right. At $130,000 it can leave you thousands of dollars short on April 30, which is the precise moment you least want a surprise. Let's replace the guess with your number.

Why everyone says "25–30%"

Because it is safe to say and impossible to be specifically wrong about. Most guides for Canadian freelancers hand you the same range, with no province, no income level, and no mention of why the percentage climbs as you earn more. The range is a real average across real freelancers. The problem is that nobody is average in the way an average needs them to be — and the error is not symmetric. If your true number is 24% and you saved 25%, you get a small refund-feeling in April. If your true number is 31% and you saved 25%, you owe a four-figure gap, all at once.

So the honest answer to "what percentage should I save?" is: it depends on three things, and all three are knowable.

The three things your real number depends on

1. Your income level

Canada's income tax is progressive: in 2026, the federal rate is 14% on your first $58,523 of taxable income, 20.5% from there to $117,045, and 26% from $117,045 to $181,440, with higher rates above that. Every dollar you earn past a threshold is taxed at the higher rate — which means your overall percentage drifts upward as your income grows. A set-aside rule that ignores your income level is ignoring the basic shape of the system.

2. Your province

Provincial tax is its own progressive ladder stacked on the federal one, and the ladders differ a lot. Ontario starts at 5.05% on the first $53,891. Quebec's rates run materially higher, and Quebec freelancers pay into QPP rather than CPP. Two freelancers with identical income in different provinces can be several thousand dollars apart on the same April 30 bill.

3. CPP, both halves

This is the one that genuinely ambushes people in year one. An employee pays 5.95% into CPP and their employer matches it. When you are self-employed, you are both people. You contribute 11.9% of your net self-employment earnings between $3,500 and $74,600, to a maximum of about $8,461 for 2026 — plus a smaller second contribution (CPP2) on earnings between $74,600 and $85,000. On a $90,000 year, CPP alone is roughly nine thousand dollars that no income-tax bracket table warned you about. It is not a penalty. It is your pension. But it has to be in the jar.

Your number, worked out honestly

Here is what the 2026 math looks like for a freelancer in Ontario, at three income levels. These are estimates of income tax (federal + provincial, including Ontario's surtax and health premium) plus CPP, assuming your only income is self-employment income and claiming only the basic personal amounts ($16,452 federal; $12,989 Ontario). Your return will differ — other deductions, RRSP contributions, and credits all move the number. The point is the shape.

Net self-employment income (ON, 2026)	Estimated tax + CPP	Your real set-aside	Flat 25% saves	The gap
$50,000	≈ $11,900	≈ 24%	$12,500	≈ $600 over — fine
$90,000	≈ $26,400	≈ 29%	$22,500	≈ $3,900 short
$130,000	≈ $40,200	≈ 31%	$32,500	≈ $7,700 short

Read the right-hand column slowly. At $50,000, the flat rule quietly over-saves and you will be fine. At $90,000, it leaves you almost four thousand dollars short. At $130,000, the shortfall is the price of a used car. The flat rule does not fail loudly — it fails in April, all at once, after a year of feeling responsible.

This table is, more or less, why VRITTI's tax estimator exists. We started with the same flat 25% everyone recommends, ran the real progressive math — federal plus all thirteen provinces and territories, CPP both halves — and watched the flat rule quietly under-save the people earning the most. That felt like the opposite of the point, so the app computes your actual marginal picture instead and skims the right slice from each payment as it arrives.

The mechanism matters more than the math

Here is the part most guides skip entirely: when you set the money aside matters as much as how much.

The failure mode is rarely "I calculated 25% instead of 29%." It is "I meant to move money over in March and the money was already gone." A percentage you apply once a quarter, from whatever happens to be left, is a wish. A percentage you skim the day a payment lands is a system.

The move: every time a client payment arrives, transfer your percentage to a separate account before you touch the rest. Same day. The slice was never yours to spend, so treat it that way from the first minute. After a few months the skim is boring, and boring is exactly what you want your tax life to be. April stops being a reckoning and becomes a transfer.

What the set-aside is actually for

Two things, on a calendar you should know cold:

Date	What it is
April 30	Your balance owing for last year is due — even though, as a self-employed filer, your return is not due until June 15. Interest starts May 1 on anything unpaid.
June 15	Your filing deadline (the return itself).
Mar 15 / Jun 15 / Sep 15 / Dec 15	Quarterly instalment due dates, once the CRA expects you to pay as you go.

The instalment system catches up with most successful freelancers eventually: once your net tax owing is more than $3,000 ($1,800 in Quebec) in the current year and in either of the two previous years, the CRA asks you to pay quarterly instead of annually. The first instalment reminder letter rattles people, but if you have been skimming all year, it changes nothing — the money is already sitting there, and the letter is just a schedule for handing it over. (More on that letter in our instalment reminder guide.)

What NOT to count: GST/HST is not yours

One trap worth naming plainly. If you are registered for GST/HST — which becomes mandatory once your taxable sales pass $30,000 over four consecutive calendar quarters — the tax you collect on invoices is not income and not savings. You are holding it in trust for the CRA. It does not belong in your set-aside percentage, it does not count toward your tax jar, and it absolutely cannot be spent "for now."

Keep it in its own mental (ideally literal) compartment: income tax set-aside is your money, earmarked; collected GST/HST is the CRA's money, parked. Mixing the two is how a healthy-looking account balance turns into two bills you can only pay one of.

The number matters less than never having to find it all at once

Work out your real percentage — your income, your province, CPP included — and then automate the skim so the question stops recurring. Whether your number is 24% or 31%, the freelancers who feel calm in April are not the ones who computed it to the decimal. They are the ones for whom the money was simply already there, moved one unremarkable slice at a time, so that tax season arrived and asked them for nothing they hadn't already set down.
