How to Start a Sole Proprietorship in Quebec: 6 Steps for 2026

You want to work for yourself, but you're not sure where to begin. Here's the good news: starting a sole proprietorship in Quebec takes just a few days, costs as little as $41, and can be done entirely online.

Our tax accountants walk you through every concrete step: registration with the REQ, tax enrolment, GST/QST thresholds, and your first deductions — all based on the rules in effect for 2026.

What Is a Sole Proprietorship in Quebec?

A sole proprietorship — also called a self-employment business or individual proprietor — is a business operated by a single person with no legal distinction between the owner and the business. It is the simplest business structure available in Quebec: no articles of incorporation, no shareholders, no board of directors. Choosing this path means operating as a self-employed individual in the eyes of both the CRA and Revenu Québec.

Before you launch, two key realities are worth understanding:

• Unlimited personal liability: your personal assets can be seized to cover business debts. Unlike a corporation, no legal shield protects your personal finances.
• Personal income taxation: your business income is added to your other income and taxed at the progressive personal rate.

Advantages and Disadvantages of a Sole Proprietorship

A sole proprietorship is often the first choice for new entrepreneurs — and for good reason. It has genuine strengths, along with limits you should understand from day one.

What Self-Employment Offers You

Fast and affordable start. Registering with the REQ costs $41 and takes a few hours online. No articles to draft, no legal fees at startup. It is the most accessible structure for starting a business in Quebec without committing significant resources.

Full control. You make every decision independently, without consulting a partner or board. That day-to-day autonomy is a real and practical advantage.

Simplified taxation. Your business income flows directly into your personal income tax return. No separate corporate filing, no complex accounting structure at the start.

Deductible losses. If your business generates losses in its early years, you can deduct them from your other personal income — which can lower your overall tax bill.

Its Limits

Unlimited personal liability. This is the most significant drawback. Your personal assets — home, savings, car — can be used to satisfy business creditors. The higher the commercial risk of your activity, the more this matters.

Progressive taxation. Your business income is added to your personal income and taxed at the progressive personal rate. As your sole proprietorship becomes more profitable, your marginal tax rate rises accordingly. This is a natural threshold to monitor as your revenue grows, and a key reason many business owners eventually consider incorporating.

No built-in benefits. Unlike an employee, you pay both the employee and employer portions of QPP (Quebec Pension Plan) contributions, and you have no access to employment insurance if your activity stops.

Limited financial credibility. Financial institutions typically view sole proprietorships as less stable structures. Securing a business loan or landing certain contracts may be harder than with an incorporated company.

In summary, a sole proprietorship is an excellent entry point into entrepreneurship. Its limitations are not flaws — they are signals to watch as your business grows and your needs evolve.

Step 1 — Determine Whether REQ Registration Is Required

First decision: do you need to register with the Registraire des entreprises du Québec (REQ)?

If you operate under your full legal name (e.g., "Marie Tremblay, Translator"), registration is optional. As soon as you use any other trade name — even a partial variation (e.g., "MT Translation Services") — registration becomes mandatory within 60 days of starting your activities.

Why register even when it's not required? Registration gives you a Quebec Business Number (NEQ) — your official identifier for opening a business bank account, accessing government programmes, and building credibility with clients and suppliers.

Step 2 — Choose and Verify Your Trade Name

If you use a name other than your full legal name, that name must comply with REQ rules:

• It must be in French or include an official French version
• It must not be identical or too similar to an already-registered name
• It must not suggest the business is a corporation or a government body

Check name availability through the Quebec Business Registry before submitting your application.

Step 3 — Register Online with the REQ

Registration is completed entirely online through the Start a Business portal on Quebec.ca (French Only). This centralized portal covers your REQ filing, Revenu Québec enrolment, and other government steps in a single session.

What you'll need:

• Your Social Insurance Number (SIN)
• Your business address
• Your most recent Revenu Québec notice of assessment number
• A description of your activities

In 2026, the fee is $41 at the regular rate and $61.50 at the priority rate, as per the official REQ fees.

Step 4 — Register with Revenu Québec and the CRA

Once you have your NEQ, two tax registrations may apply depending on your situation.

Revenu Québec: register through Mon dossier pour les entreprises or directly through the Start a Business portal. This gives you your provincial tax numbers.

Canada Revenue Agency (CRA): if you have employees or your revenue exceeds certain thresholds, federal registration is required to obtain your Business Number (BN).

Step 5 — Determine Whether You Need to Register for GST/QST

This is the obligation many new self-employed individuals discover too late — sometimes with serious financial consequences.

According to Revenu Québec, you must register for both GST and QST once your total taxable supplies exceed $30,000 in a single calendar quarter or over the previous four quarters. Below this threshold, you are considered a "small supplier" and registration is optional.

If you exceed the $30,000 threshold without registering, Revenu Québec can require retroactive payment of uncollected taxes — drawn from your personal cash flow.

Voluntary registration under $30,000: this can be advantageous if you incur significant business expenses, since it allows you to claim Input Tax Credits (ITCs) and Input Tax Refunds (ITRs) to recover the taxes paid on your purchases.

Certain activities require immediate registration regardless of revenue — taxi, ridesharing, gasoline sales, and other regulated sectors.

Step 6 — Check Permits Specific to Your Sector

Some industries require licences or permits before you can legally operate:

• Food and restaurant: permit from MAPAQ
• Construction: licence from the Régie du bâtiment du Québec (RBQ)
• Financial services: oversight by the Autorité des marchés financiers (AMF)
• Regulated professions: law, medicine, accounting — governed by their respective professional orders

Sole Proprietorship Taxation: What Comes Back Every Year

The six steps above bring you into compliance as a self-employed individual in Quebec. Here is what recurs annually.

Personal Income Tax Return

Your business income is reported on your personal income tax return — both to Revenu Québec and to the CRA. It is added to your other income (if you are also employed by a company at the same time) and taxed at the progressive personal rate.

Keep accurate records of all your revenue and expenses throughout the year to properly track all income and expenses related to your self-employment activity.

Quarterly Instalment Payments

If your estimated tax liability exceeds $1,800 provincially or $3,000 federally for the year, you must make instalment payments in March, June, September, and December. Missing these deadlines results in interest charges from both levels of government.

QPP Contributions

Unlike an employee, you pay both the employee and employer shares of Quebec Pension Plan (QPP) contributions — approximately 12.8% of your net business income in 2026. This is a cost that many new sole proprietors underestimate in their financial planning.

How Do You Pay Yourself as a Sole Proprietor?

This is one of the most common questions from new self-employed individuals. Unlike a corporation, a sole proprietorship has no salary or dividend mechanism. You simply draw money from your business as needed — these are called owner's draws. Your taxable income is your net business profit (revenue minus deductible expenses), regardless of how much you actually withdrew during the year.

Deductible Business Expenses

Sole proprietorship taxation allows you to deduct expenses incurred to earn business income. The list of deductible business expenses in Canada is longer than most people expect: home office expenses, vehicle costs, equipment, professional development, and accounting fees.

When Should You Consider Incorporating?

As your activity grows, the question of sole proprietorship vs corporation in Canada comes up naturally. In practice, it is worth evaluating when your net income regularly exceeds $50,000 to $80,000 per year, when you want to protect your personal assets, or when you are planning to eventually sell your business.

The transition can often be made without immediate tax impact through the tax rollover provisions under Section 85 of the Income Tax Act (ITA). For a full breakdown, read our article on the advantages and disadvantages of incorporating in Quebec.

This decision depends on many factors specific to your situation. Consulting a CPA before acting is recommended.

FAQ — Starting a Sole Proprietorship in Quebec

How do I register a sole proprietorship in Quebec online?

Through the Start a Business portal on Quebec.ca. You will need your SIN, your business address, and your most recent Revenu Québec notice of assessment number. The fee is $41 at the regular rate in 2026. If you operate under your full legal name, no registration is required — a NEQ only becomes mandatory if you use a different trade name.

How much does it cost to register a sole proprietorship in Quebec?

If you operate under your full legal name, there is no cost. If you register with the REQ — by choice or obligation — the fee is $41 at the regular rate or $61.50 at the priority rate in 2026. Annual update fees may apply thereafter.

Does a sole proprietor need a business number in Canada?

You will need a Business Number (BN) from the CRA if you have employees or if you are required to register for GST/QST. The NEQ (provincial) and the BN (federal) are two distinct identifiers — you may need one, both, or neither depending on your situation.

Does a sole proprietor need to collect sales tax?

Yes, once your taxable supplies exceed $30,000 in a calendar quarter or over four consecutive quarters. Below that threshold, registration for GST and QST is optional — though it may still be beneficial if you incur significant business expenses and want to recover Input Tax Credits (ITCs).

Do I need to make instalment payments as a self-employed individual?

Yes, if your estimated tax liability exceeds $1,800 provincially or $3,000 federally for the year. These payments are quarterly: March, June, September, and December. Failing to make them results in interest charges on the amounts owed.

Can a sole proprietor have a company name?

Yes. If you want to operate under a name other than your full legal name, you must register that trade name with the REQ within 60 days of starting operations. The name must comply with REQ rules, including a French version requirement.

Do I need to register as a sole proprietor in Quebec?

It depends on the name you use. Operating under your full legal name requires no registration. Using any other trade name — even partially different from your legal name — triggers a mandatory REQ registration within 60 days.

How do I incorporate a sole proprietorship in Canada?

You cannot technically "convert" a sole proprietorship into a corporation — you incorporate a new entity and transfer your business assets to it. This can often be done tax-free using the Section 85 rollover under the Income Tax Act. A CPA can structure the transfer to minimize the tax impact.

What are the main risks of a sole proprietorship?

Unlimited personal liability is the primary risk: a business debt can result in seizure of your personal assets. The secondary risk is tax-related: as your income grows, your marginal rate increases, making incorporation progressively more advantageous.

Start Your Business in Quebec as a Sole Proprietor

Starting a sole proprietorship in Quebec is an excellent first step. The process is straightforward, the costs are minimal, and your initial tax obligations are manageable with basic organisation.
