Self-Employed Tax Calculator Canada: How Much Tax Will You Owe for 2026?

When you work for yourself in Canada, nobody holds tax back, so the bill lands all at once: pension contributions, federal tax, and provincial tax. Type your net self-employment income (after expenses) and your province, and this page reads you the estimated total for 2026 and the monthly amount to set aside. It assumes this is your only income. The math runs in your browser; the numbers you type are never sent anywhere.

Your numbers

Your self-employment income

Net self-employment income for the year ($)

What is left after business expenses, the amount your return starts from. This calculator assumes it is your only income for the year.

Province or territory where you live

Your province of residence on December 31 sets your provincial tax. Quebec is in the list too: it runs its own pension plan, the QPP, and its own tax, and both are worked in.

Estimated total owed for 2026 Your number is waiting

Type your numbers above to see your estimate.

Canada Pension Plan (CPP) $0 Both halves, employee and employer, because you are both.

Federal tax $0 After the basic personal amount and the pension credit.

Provincial tax $0 Your province's tax, after its basic personal amount and the pension credit.

Effective tax rate 0 The total owed as a share of your net income, pension included.

You keep after the bill $0 Net income minus the total owed.

Set aside each month $0 The total owed divided by 12, so the bill is covered when it comes due.

Picture tax time with the money already waiting in its own account: the bill arrives, you pay it from what you set aside each month, and the rest of your income stays free for the life you are building.

Pension first, on income between the $3,500 exemption and the ceilings. Then tax on what is left after the deductible part of the pension comes off your income, with credits for the basic personal amounts and for the credit base, which is half of the base portion of the pension.

The formula in plain words: as a self-employed person you pay both halves of the pension plan. The tax system softens that in two ways, set out in CRA Schedule 8: half of the base portion of the contribution earns a credit against your tax, and everything else, the other half of the base portion plus the enhanced portion and CPP2, is deducted from your income before tax. This calculator applies both, the same way a return does.

What this free calculator did not calculate. One net self-employment income for 2026, with no other income. No other credits or deductions beyond the basic personal amounts and the pension split, and no high-income reduction to those amounts. No Employment Insurance, which is opt-in when you are self-employed, and no Quebec Parental Insurance Plan premiums in Quebec. No GST or HST, and no provincial surtaxes or health premiums. The full workbook below tracks income, expenses, instalments, and GST or HST across all provinces all year, and the 2026 Self-Employed Tax Filing Planner (CA$27.99) walks the filing itself step by step.

How the self-employed tax calculator works

Updated November 2026

Why the self-employed bill feels bigger

An employee sees tax and CPP come off every paycheque, and the employer quietly pays half the CPP on top. When you work for yourself, none of that happens during the year. You owe the income tax, and you owe both halves of the pension plan, all on the same return. The total is not a penalty; it is the employee share, the employer share, and the tax, arriving together.

The steps, in plain words

Four steps, and the calculator above runs exactly these:

Step 1: the pension contributions. CPP takes 11.9 percent of net income between the $3,500 basic exemption and $74,600, then 8 percent more on income from $74,600 to $85,000. The most anyone pays for 2026 is $9,292.90. Quebec's QPP takes 12.6 percent on the first band and 8 percent on the second, to a maximum of $9,790.60. The first band itself has two parts: a base portion (9.9 percent for CPP, 10.6 percent for the QPP) and a 2.0 percent enhanced portion. The 8 percent second band is the second additional plan, CPP2 (QPP2 in Quebec).

Step 2: the deduction. This is the split set out in CRA Schedule 8. Only the base portion divides in two: one half of it becomes the credit base used in Step 4. Everything else is deducted from your income: the other half of the base portion, the enhanced portion in full, and the whole second band (CPP2 or QPP2). What is left after the deduction is your taxable income.

Step 3: the tax. The 2026 federal brackets tax the taxable income, and so do your province's brackets. In Quebec, the federal result is then reduced by the 16.5 percent Quebec abatement.

Step 4: the credits. Each level takes off its basic personal amount credit (the amount times its lowest rate) and a credit on the credit base, which is half of the base portion of your pension contributions, also at the lowest rate. Credits are non-refundable, so neither tax can go below zero. Add the pension total back on, and that is the estimated bill.

A worked example

Take the numbers this calculator opens with. Net self-employment income of $80,000, your only income, for 2026 in Ontario.

Step 1: the first band is $8,460.90 (11.9 percent of $71,100), made of a base portion of $7,038.90 (9.9 percent) and an enhanced portion of $1,422.00 (2.0 percent), plus $432.00 on the second band (8 percent of $5,400), for a pension total of $8,892.90. Step 2: the credit base is half of the base portion, $3,519.45, and the deduction is the rest, $5,373.45, which comes off the income and leaves taxable income of $74,626.55. Steps 3 and 4: federal tax comes to $8,698.45 and Ontario tax to $3,785.13, each after its basic personal amount credit and the pension credit. The total owed is $21,376.48, an effective rate of 26.72 percent. You keep $58,623.52, and setting aside $1,781.37 a month covers the bill when it comes due.

The same $80,000 in Quebec: QPP is $9,390.60 (a base portion of $7,536.60, an enhanced portion of $1,422.00, and $432.00 of QPP2), the credit base is $3,768.30 and the deduction is $5,622.30, federal tax after the abatement is $7,191.51, Quebec tax is $8,233.67, and the total is $24,815.78, before Quebec Parental Insurance Plan premiums, which this calculator leaves out.

How to read your result

The total owed is the headline: pension, federal tax, and provincial tax together. The effective rate puts that total against your net income, which is the honest way to compare this year with a salaried year. The monthly set-aside is the habit that makes the bill boring: move that amount to a separate account every month, and tax time stops being a surprise. If you also have a salary or other income, your real bill will differ, because the pension and the brackets are shared across all your income; that fuller picture is what the workbook and a tax pro are for.

What the math takes as given, and what it leaves out

The math covers one net self-employment income for 2026, with no other income, full basic personal amounts at every income, and the pension split described above. It leaves out every other credit and deduction, the reduction to the basic personal amount at high incomes (federal, and the Manitoba and Yukon amounts that follow similar rules), Employment Insurance, which self-employed people join only by choice, GST and HST, provincial surtaxes and health premiums, provincial tax reductions, and Quebec Parental Insurance Plan premiums. Your real return can differ, so treat the result as an estimate, not a filing.

The filing side of the same numbers

Knowing the bill is half the work. The other half is the filing itself: which forms, which deadlines, and how instalments work when the bill is large. The Kollaz Money guide Sole Proprietor Taxes Canada 2026: What You Owe, When It's Due, and How to Pay walks through it in plain words. And once you know what the year costs, the free freelancer rate calculator makes sure the rate you charge covers it.

Frequently asked questions

How does this calculator work out my tax?

It runs the same steps a Canadian self-employed return runs, in a simplified form. First it works out your pension contributions on your net self-employment income: CPP everywhere except Quebec, which has the QPP. Then it applies the pension split from CRA Schedule 8: only the base portion of the contribution splits, with half of it forming the credit base, while the rest of the contribution is deducted from your income, like the deduction on a real return. Next it taxes what is left with the 2026 federal brackets and your province's brackets. Last, it takes off the basic personal amount credits and a credit on the credit base, at the lowest federal and provincial rates. What is left, plus the pension contributions themselves, is your estimated total owed.

Why do I pay both halves of the pension plan?

An employee pays one half of CPP and the employer pays the other half. When you are self-employed, you are both, so you pay both halves yourself on your tax return. For 2026 the self-employed CPP rate is 11.9 percent on income between the $3,500 basic exemption and $74,600, plus 8 percent on income from $74,600 to $85,000, for a maximum of $9,292.90. Under CRA Schedule 8, half of the base portion of what you pay earns a credit, and the rest, including the enhanced portion and CPP2 in full, is deducted from your income, which is how this calculator treats it.

What is different in Quebec?

Quebec runs its own pension plan, the QPP, and its own income tax through Revenu Quebec. The self-employed QPP rate for 2026 is 12.6 percent between the $3,500 exemption and $74,600, plus 8 percent up to $85,000, for a maximum of $9,790.60. Quebec income tax has its own brackets and a basic personal amount of $18,952, and the federal tax is reduced by the 16.5 percent Quebec abatement. This calculator includes all of that. It does not include Quebec Parental Insurance Plan premiums, which self-employed workers in Quebec also pay.

What does this calculator leave out?

It covers one net self-employment income for 2026, with no other income, and the basic personal amounts as the only credits besides the pension credit. It leaves out every other credit and deduction, the reduction to the basic personal amount at high incomes, Employment Insurance (which is opt-in when you are self-employed), GST and HST, provincial surtaxes and health premiums, and Quebec Parental Insurance Plan premiums. Your real return can differ, so treat the result as an estimate.

Where does my information go when I use this calculator?

Is this tax advice?

No. It is arithmetic on the numbers you type, using the published 2026 federal and provincial rates and credits. It does not know your full return, your other credits, or your life. For decisions about your specific situation, talk to a qualified tax professional.
