Self-Employed Tax Calculator Québec 2026

Short answer A self-employed person in Québec with no other income pays about 20% of profit in tax and contributions at $30,000, 28% at $60,000, 34% at $100,000 and 37% at $150,000 in 2026. That includes federal tax after the 16.5% Québec abatement, Québec tax, both halves of the QPP (12.6% plus 8% on the top band, up to $9,790.60), QPIP at 0.764% and the health services fund contribution. Nothing is withheld, so set the money aside as you earn it: the balance is due April 30, 2027, even though you have until June 15, 2027 to file.

Self-employed tax calculator, Québec 2026

Item	Amount

Estimate only, not tax advice, using 2026 rates in effect on November 9, 2026: a single person, resident in Québec all year, aged 18 to 64, carrying on a business in Québec and not registered for EI special benefits for the self-employed. Only the basic personal amounts, the Canada employment amount (on salary only), the Québec deduction for workers, the credits and deductions tied to QPP, QPIP and EI, and the RRSP deduction are included. Other credits (living alone, medical, donations, children), refundable credits, the alternative minimum tax and the prescription drug insurance premium are excluded. Salary is assumed to come from one employer with correct withholdings.

How to use the self-employed tax calculator

The calculator estimates the tax and contributions on one year of self-employment income in Québec, using the 2026 rates. Only the first amount is required; leave the others blank if they don’t apply.

Gross revenue: what you invoiced or earned from your business in 2026, without the GST and QST you charged. Sales taxes are not income; they go back to Revenu Québec.
Business expenses: the deductible costs of earning that revenue, such as supplies, software, the business share of your phone and vehicle, home office costs and capital cost allowance. If you already know your net profit from your books, tick the box and enter it directly. A loss can be entered as a negative number.
Employment salary: if you also had a job in 2026, enter the gross salary from your T4 and RL-1. Your employer already withheld QPP and QPIP on that pay, and the calculator subtracts that from what the business owes. It also assumes the tax on your salary was withheld, so the tax lines show only the extra tax your business income creates.
RRSP contribution: the amount you plan to deduct for 2026. It lowers income tax on both returns but not the QPP, QPIP or health services fund.

The results update as you type. The bottom of the table shows a monthly amount to set aside and whether federal or Québec instalments are likely if your income stays at this level.

How self-employed income is taxed in Québec

There is no separate tax rate for the self-employed. Your net business income (revenue minus deductible expenses) is added to your other income on two personal returns: the federal T1, with form T2125 for the business, and the Québec TP-1, with form TP-80. On that profit you pay five things:

Federal income tax at the 2026 rates of 14%, 20.5%, 26%, 29% and 33%, reduced by the Québec abatement of 16.5% of basic federal tax.
Québec income tax at 14%, 19%, 24% and 25.75%.
QPP contributions, both the employee and the employer share.
QPIP premiums at the self-employed rate.
The health services fund (HSF) contribution, which applies to business income but not to salary.

Employees pay the same income tax, but their employer withholds it from every pay and pays half of the QPP. The self-employed pay everything themselves, once a year or through instalments. That is why the same $60,000 feels more expensive as a freelancer: the bill is the same order of magnitude, but it arrives all at once and includes the employer’s share of the QPP. Our self-employed tax guide covers the forms line by line.

Self-employed tax in Québec: 2026 results by income

These figures come from the calculator, for a single person whose only income is self-employment profit, with no RRSP contribution. “Total” is all tax and contributions; “Rate” is total divided by profit.

Net business income	QPP (both halves)	QPIP	HSF	Federal tax	Québec tax	Total	Rate	Per month
$30,000	$3,339	$229	$95	$1,167	$1,059	$5,888	19.6%	$491
$60,000	$7,119	$458	$150	$4,205	$4,938	$16,871	28.1%	$1,406
$100,000	$9,791	$764	$443	$10,439	$12,146	$33,583	33.6%	$2,799
$150,000	$9,791	$787	$943	$20,216	$23,493	$55,230	36.8%	$4,602

Three things stand out. First, at lower incomes the QPP is larger than federal and Québec income tax combined. Second, the QPP stops growing at $85,000 of earnings, so from about $100,000 the rate climbs more slowly until the top brackets start. Third, the cost of the next dollar is high early: about 37 cents per extra dollar from $25,000 to $60,000, because the 12.6% QPP rate stacks on a 25.69% combined income tax rate (partly offset by the QPP deduction and credit). It peaks at 43 to 47 cents between about $65,000 and $85,000, where full QPP meets the 20.5% federal and 19% Québec brackets, drops to about 38 cents once the QPP is maxed out, then rises to 47 to 50 cents above $125,000.

With a job on the side. Take $60,000 of profit plus a $50,000 salary. The salary already covered QPP on its first $50,000 of earnings, so the business pays only $3,932 of QPP on the room left up to $85,000, plus $405 of QPIP and $150 of HSF. But the profit lands in higher brackets: the extra federal tax is $9,124 and the extra Québec tax $10,554, for $24,164 in total, or 40.3% of the business income. A side business taxed on top of a salary costs more per dollar than the same business on its own, even with a smaller QPP bill.

Why your QPP doubles when you’re self-employed

An employee pays 6.3% of earnings between $3,500 and $74,600 in 2026 (5.3% base plus 1% first additional contribution) and 4% between $74,600 and $85,000 (the second additional contribution). The employer matches both. A self-employed person is both, so the rates on net business income are:

2026 QPP on self-employment	Rate	Earnings band	Maximum
Base contribution (both halves)	10.6%	$3,500 to $74,600	$7,536.60
First additional contribution (both halves)	2%	$3,500 to $74,600	$1,422.00
Second additional contribution (both halves)	8%	$74,600 to $85,000	$832.00
Total			$9,790.60

The QPP is calculated on Schedule U of the Québec return and paid to Revenu Québec with your balance or your instalments. Both returns then soften it the same way:

Deducted from income on both returns: the “employer” half of the base contribution (5.3%), the full first additional contribution (2%) and the full second additional contribution (8%). Federally this is line 22200; on the Québec return, line 248.
Federal non-refundable credit: the “employee” half of the base contribution (5.3%) gives a 14% credit on line 31000.
No Québec credit: Québec gives no credit for QPP contributions. Instead, its basic personal amount is higher ($18,952 in 2026) and it grants the deduction for workers.

At $60,000 of profit, $7,119 of QPP comes with $4,124 of deductions and a credit on $2,995, so its real after-tax cost is lower than it looks. And it is not lost: it buys an indexed lifetime pension and disability and survivor coverage, in the same way an employee’s contributions do.

If you also have a salary, your employment and self-employment earnings are combined on Schedule U, and only one $3,500 exemption and one set of ceilings applies. Twice the employee contributions already withheld from your pay are credited against the self-employed amount. A salary of $85,000 or more already maxes out the QPP, so business income on top of it adds no QPP at all. A business loss does not reduce the QPP withheld on a salary.

QPIP for the self-employed

The Québec parental insurance plan funds maternity, paternity, parental and adoption benefits, and the self-employed are covered. The 2026 self-employed rate is 0.764% of net business income, down from 0.878% in 2025, on income up to the $103,000 maximum insurable earnings. The maximum premium is $786.92. If you also earn a salary, the ceiling is shared: business income is insured only up to what your salary has not already used.

You pay no premium if your net business income and insurable employment income total less than $2,000. About 43.7% of the premium (the part above the employee rate of 0.430%) is deductible on both returns, through line 22300 federally and line 248 in Québec, and the rest gives a federal credit. The upside: if you plan a child, your QPIP benefits are based on these insured earnings, so a year of good profit is also a year of coverage.

Do self-employed people pay EI?

No, not by default. Employment Insurance does not cover self-employment, and there is no premium on business income. You can sign an agreement with the Canada Employment Insurance Commission to join the EI special benefits program for the self-employed, which covers sickness, compassionate care and family caregiver benefits. Once you opt in, premiums are calculated on your self-employment earnings each year. In Québec, maternity and parental benefits come from QPIP, not EI. The calculator assumes you have not opted in.

The health services fund contribution on business income

Employees never see this one, because their employer pays the HSF on payroll. Individuals pay an HSF contribution on income other than employment income: business income, rental and investment income, pensions and capital gains. It is calculated on Schedule F and added to your Québec balance on line 446.

Schedule F starts with your total income, takes out employment income and a few other items, then subtracts the QPP and QPIP deductions on your business income. Your RRSP deduction and the deduction for workers do not reduce it. For 2026:

Income subject to the contribution, 2026	HSF contribution
$18,500 or less	$0
$18,500 to $33,500	1% of the excess over $18,500
$33,500 to $64,355	$150
Over $64,355	$150 plus 1% of the excess over $64,355, up to $1,000

The $1,000 maximum is reached at $149,355 of income subject to the contribution. Revenu Québec’s own estimate tables apply these brackets to net business income directly, which gives a slightly higher figure; Schedule F, which is what you file, subtracts the QPP and QPIP deductions first, and that is what the calculator does. At $100,000 of profit the difference is about $60.

The Québec deduction for workers, and what the self-employed don’t get

Québec’s deduction for workers is 6% of eligible work income, up to $1,450 for 2026, and net business income counts toward it along with salary. It is reached at about $24,200 of combined work income, so most self-employed people get the full amount. It reduces Québec taxable income only.

The federal Canada employment amount ($1,501 for 2026) is a different story: it applies only to employment income. A freelancer with no salary can’t claim it, which is one reason employees and the self-employed with the same income don’t pay exactly the same federal tax.

How much should you set aside for taxes?

Since nothing is withheld from your invoices, the safest habit is to move a fixed share of every payment you receive into a separate savings account. Based on 2026 rates, for a single person with no other income:

Profit around $30,000: set aside about 20%.
Profit around $45,000 to $60,000: about 25% to 28%.
Profit around $85,000 to $100,000: about 33% to 34%.
Profit around $150,000: about 37%, and closer to 40% at $200,000.
Side business on top of a full-time salary: often 37% to 45% of the business profit, because it is taxed in your top bracket.

Apply the percentage to profit, not revenue: on a $1,000 invoice with $200 of related expenses, set aside your rate on $800. Keep the GST and QST you collect in the same account, because they belong to the government. The calculator turns your estimate into a monthly amount; if your income is seasonal, set aside the percentage on each payment instead of a flat amount.

Instalments: when the government asks you to prepay

Once your tax bill is large enough, the CRA and Revenu Québec stop waiting for April. For Québec residents, both use the same $1,800 threshold, applied separately to each government:

CRA: you must pay federal instalments for 2027 if your net federal tax owing is more than $1,800 for 2027 and was more than $1,800 for 2026 or 2025.
Revenu Québec: you must pay instalments if your net Québec income tax payable is expected to be more than $1,800 for the year and was more than $1,800 for either of the two previous years. Once you have to pay them, the instalments also cover your QPP, QPIP and HSF.

Instalments are due March 15, June 15, September 15 and December 15. In your first profitable year there are usually none, because the previous years don’t meet the test, so your whole first bill lands on April 30. That is the year people get caught. The calculator flags instalments as “likely if this repeats” when this year’s balance passes $1,800, meaning that if next year looks similar, you will probably receive reminders from both governments. For a single person with no other income, that happens at about $36,000 of profit on both sides. Our tax instalments guide explains the three ways to calculate the payments and how interest is charged.

File by June 15, pay by April 30

Self-employed people and their spouses have until June 15 to file their returns. For the 2026 tax year, that is June 15, 2027. But the payment deadline does not move: any balance owing for 2026, including QPP, QPIP and the HSF, is due April 30, 2027. Interest runs from May 1 on anything unpaid, even if you file on time in June.

The practical rule is to do your numbers in March or April, pay both governments by April 30, and use the extra time only for the paperwork. If you can’t pay in full, file on time anyway: late-filing penalties are charged on top of interest, by each government. All the dates are on our Québec tax deadline calendar.

Lower the bill legally: expenses and RRSP

Every deductible dollar of expense reduces income tax, QPP, QPIP and the HSF at the same time, which makes it worth more to the self-employed than any personal deduction. At $60,000 of profit, $1,000 of extra legitimate expenses saves about $364. The main categories are supplies and software, professional fees, advertising, the business share of your phone, internet and vehicle (with a logbook), home office costs and capital cost allowance on equipment. Québec limits some home office costs to 50% and caps meals and entertainment based on your sales. Our complete list of self-employed deductions in Québec covers each one, with the 2026 limits.

An RRSP contribution works differently. It reduces income tax only. At $60,000 of profit, deducting $5,000 cuts the bill from $16,871 to $15,586, a saving of $1,285, or about 26%. The QPP stays the same. Your RRSP room depends on your previous year’s earned income, which includes net business income.

GST and QST are a separate account

The calculator ignores sales taxes because they are not income. If your worldwide taxable sales pass $30,000 in a calendar quarter or over four consecutive quarters, you must register with Revenu Québec, which administers both the GST and the QST in Québec, and charge 5% GST and 9.975% QST. Taxi and ride-hailing drivers must register from the first dollar. You then claim back the taxes paid on business purchases. To price an invoice or back taxes out of a total, use our GST/QST calculator, and read our GST/QST guide for small businesses for registration, filing periods and the quick method.

When does incorporating start to make sense?

A corporation doesn’t make the tax disappear; it lets you defer it. Profit left in the corporation is taxed at 12.2% if it qualifies for the Québec small business deduction, or 20.5% if it doesn’t, which is the case for most one-person service corporations because of the 5,500 paid-hour test. Personal tax is paid later, when you take the money out as salary or dividends.

That deferral helps only if you can leave money in the company. For a solo owner in Québec, incorporating usually starts to pay off around $120,000 to $150,000 of profit, and only if you live on noticeably less than that. Below that level, or if you take everything out every year, the accounting, legal and annual filing costs usually cancel the benefit. Read should you incorporate in Québec? for the full analysis, and use our salary vs dividends calculator to see what you would take home once incorporated.

Common mistakes we see with self-employed taxes

Paying on June 15. June 15 is the filing deadline. The balance was due April 30, and interest has been running since May 1.
Budgeting for income tax but not the QPP. At $40,000 of profit the QPP alone is $4,599.
Forgetting the HSF. It is small, up to $1,000, but it is on your Québec bill and not on most online calculators.
Setting aside a percentage of revenue taken from someone else’s situation. A freelancer with a full-time job needs a much higher rate on business profit than one with no salary.
Counting the GST and QST as income, or spending them before the return is due.
Ignoring the first instalment reminder. Instalment interest is compounded daily and is not deductible.
Claiming 100% of a car or phone without a logbook or a reasonable business-use percentage.
Treating a business loss as a way to recover QPP on a salary. It reduces income tax, not the QPP withheld by your employer.

What this calculator includes and leaves out

It uses the official 2026 federal and Québec brackets, the federal basic personal amount and its phase-down between $181,440 and $258,482 of net income, the Québec basic personal amount of $18,952, the 16.5% Québec abatement, the QPP rates and ceilings on Schedule U, the 2026 QPIP rates on Schedule R, the HSF calculation on Schedule F, the deduction for workers (Work Chart 201), the QPP and QPIP deductions and federal credits, and, when you enter a salary, the employee QPP, QPIP and EI withheld and the Canada employment amount.

It leaves out other non-refundable credits (living alone, age, medical expenses, donations, tuition), refundable credits and benefits (solidarity tax credit, work premium, GST credit, Canada child benefit, family allowance), the Québec prescription drug insurance premium if you are not covered by a group plan, the alternative minimum tax, capital gains and investment income, partnerships, and contributors aged 65 or older who stopped contributing to the QPP. Treat the result as a planning estimate, not tax advice. Your actual returns can differ, sometimes by several hundred dollars.

FAQ

How much tax does a self-employed person pay in Québec?

For 2026, with no other income, total tax and contributions are about 20% of profit at $30,000, 28% at $60,000, 34% at $100,000 and 37% at $150,000. That covers federal and Québec income tax, both halves of the QPP, QPIP and the health services fund contribution.

What percentage should I set aside for taxes as a freelancer in Québec?

Roughly 20% of profit at $30,000, 25% to 28% between $45,000 and $60,000, 33% to 34% around $85,000 to $100,000, and 37% or more above $150,000. If you also have a full-time salary, set aside 37% to 45% of the business profit. Keep the GST and QST you collect separately as well.

How much QPP does a self-employed person pay in 2026?

12.6% of net business income between $3,500 and $74,600, plus 8% between $74,600 and $85,000, for a maximum of $9,790.60. That is both the employee and employer shares. Part of it is deductible on both returns and part gives a federal credit. A salary from a job reduces what the business owes.

What is the QPIP rate for the self-employed in 2026?

0.764% of net business income, up to the $103,000 maximum insurable earnings, for a maximum premium of $786.92. The rate was 0.878% in 2025. No premium is due if your business and insurable employment income total less than $2,000.

Do self-employed people pay the health services fund contribution?

Yes. Business income is subject to the individual HSF contribution on Schedule F. For 2026 it is nil up to $18,500 of income subject to the contribution, 1% of the excess up to $150, a flat $150 up to $64,355, then $150 plus 1% of the excess, up to $1,000.

When do self-employed people have to pay their taxes in Québec?

The balance for 2026 is due April 30, 2027, even though the filing deadline is June 15, 2027. Interest starts on May 1. If you must pay instalments, they are due March 15, June 15, September 15 and December 15 of the tax year.

When do I have to pay tax instalments as a self-employed person?

When your net tax owing is more than $1,800 for the current year and was more than $1,800 in either of the two previous years. The test is applied separately by the CRA and by Revenu Québec. Your first profitable year usually has no instalments, so the first bill arrives all at once.

Does the calculator work if I also have a job?

Yes. Enter your salary and the calculator subtracts the QPP and QPIP already withheld from your pay, applies the shared ceilings, and shows only the extra income tax your business creates, assuming your employer withheld the right tax on the salary. It does not handle several employers or a salary paid outside Québec.
