Incorporating in Consulting Services in Quebec (2026): The Guide by Profession
In consulting services, incorporation is the industry standard: most agencies and major clients require it before signing a mandate, and no practice permit is required for the majority of consulting professions. Incorp-Québec prepares your corporation for $497 all-in, including the $397 government fee, in about 20 minutes.

Why incorporation is the standard in consulting services
No law forces a consultant to incorporate — the market does. Agencies and corporate or public clients contract with corporations, not individuals: in IT, the industry association (AQIII) estimates that about 94% of independent consultants operate as corporations, and agency onboarding guides present incorporation as the first step, even before prospecting.
The reasons are concrete: limited liability against contractual claims, the professional image expected by buyers of services, access to agency mandates and public contracts, and the ability to leave surpluses in the corporation when revenue justifies it. For the structure itself, see our comparison of legal structures in Quebec; for the right timing for your situation, our guide When should you incorporate in Quebec?.
The sector's common core: five cross-cutting issues
Whatever your specialty — strategy, IT, HR, marketing, finance — a Quebec consulting firm faces the same major questions. Each profession guide applies them to its own reality; here is the overview.
No practice permit for most consulting professions
Quebec's professional system distinguishes two regimes. Professions with exclusive practice (lawyers, notaries, engineers, architects…) reserve certain acts: you must be a member of the order to perform them. Professions with reserved title (Adm.A., CRHA/CRIA…) reserve only the title: anyone can offer management or human resources consulting without being a member — only using the title, or letting people believe you hold it, is an offence. For the vast majority of consultants, there is therefore no licence to obtain before invoicing. And for members of a professional order, Bill 67 (November 2024) reversed the logic of the Professional Code: practising through a corporation is now permitted unless expressly prohibited.
The PSB: the sector's real cross-cutting risk
Consulting's number-one trap is neither a permit nor a professional order: it's the personal services business (PSB — in French, entreprise de prestation de services personnels, or EPSP). If, without your corporation, you would reasonably be considered your client's employee — a single client, real subordination, tools supplied, imposed schedule — the tax authorities reclassify the corporation: about 44.5% combined tax instead of 20.5% for a legitimate solo consultant, denied expenses (essentially only the salary paid remains deductible), retroactively and with interest. The CRA publishes the factors it analyzes and Revenu Québec applies the same conditions; the only automatic exclusion: more than 5 full-time employees all year.
A written “independent contractor” contract does not protect you: the facts prevail. The antidotes — several clients, control over method, your own tools, real financial risk, business presence — are broken down criterion by criterion in our IT consultant guide, including the constraints the CRA considers “neutral” in agency mandates. The riskiest scenario — invoicing your former employer without changing anything — is covered in the management consultant guide.
GST/QST: the $30,000 threshold arrives fast
Registering for GST and QST becomes mandatory as soon as your taxable supplies exceed $30,000 in a calendar quarter or over the four preceding calendar quarters — in consulting services, a few weeks of invoicing is often enough. Below that, voluntary registration gives you the right to input tax credits and rebates. For your invoices, our GST/QST calculator gives the exact amounts.
Invoicing the public sector: three thresholds to know
Three thresholds mark access to public organizations: from $25,000, the Revenu Québec compliance certificate is mandatory — an outstanding account blocks it, and therefore the contract too; from $139,000 (2026-2027 threshold), the services contract goes through a public call for tenders on SEAO, where registration is free; from $1M (services), you need authorization from the Autorité des marchés publics (AMP). The full process is detailed in the management consultant guide.
Errors and omissions insurance: contractual, not legal
No law requires a consultant outside a professional order to carry professional liability (E&O) insurance, but most large clients require it by contract: no policy, no mandate. Usual limits of $1M to $5M, premiums for a solo consultant starting around $800 per year. Members of a professional order have mandatory insurance through their order.
The prerequisite for everything else: your corporation, $497 all-in
Articles of incorporation, initial declaration with the REQ and $397 government fees included. A form of about 20 minutes, filed directly with the Registraire des entreprises — your NEQ ready for agencies and clients.

CAE codes for consulting services (77xx)
When incorporating the corporation, the Registrar asks for an economic activity code (CAE) describing the main activity. Consulting services occupy the 77xx section — Business services. Our CAE code search tool covers all sectors; here is the full 77xx section. Codes marked with an asterisk (*) are reserved for members of the relevant professional order — see the box further below.

Only declare one of these codes if you are a member of the order in question; if you offer the same service without the title, use the corresponding generic code (7771, 7731, 7797…). Our CAE code search tool flags these reserved codes, and the declared code then appears in the public register — see our guide to the Quebec Enterprise Register.
FAQ — Incorporating in consulting services in Quebec
Do I need a permit to be a consultant in Quebec?
No, for most consulting professions. Titles like Adm.A. or CRHA are reserved titles: only the use of the title is protected, not the activity — anyone can offer management or HR consulting. The exceptions are professions with exclusive practice (lawyers, engineers, architects…), which correspond to the CAE codes marked with an asterisk.
What is a PSB, in a nutshell?
A corporation behind which the tax authorities see an employee incorporated as a company: without it, you would reasonably be your client's employee. Consequences: about 44.5% combined tax instead of 20.5% for a legitimate solo consultant, and almost all expenses denied except the salary paid. Automatic exception: employing more than 5 full-time employees all year.
How can I reduce PSB risk?
Diversify your clients, control your method and schedule, supply your own tools, take on real financial risk and build a genuine business presence (website, your own invoices, GST/QST, insurance). A written “independent contractor” contract is not enough: the facts prevail. A single client in ongoing subordination remains the highest-risk profile.
Which CAE code should I choose for a consulting firm?
The code in the 77xx section that best describes your main activity: 7771 for management consulting, 7721 for IT, 7741 for advertising, 7797 for design, 7799 for other business services. Watch for the codes marked with an asterisk (7732, 7751, 7752, 7761…): they are reserved for members of the relevant professional order.
How do I invoice the Quebec government?
From $25,000, the Revenu Québec compliance certificate is mandatory — an outstanding account blocks it. From $139,000 (2026-2027 threshold), the services contract goes through a public call for tenders on SEAO, where registration is free. From $1M (services), you need authorization from the Autorité des marchés publics (AMP).
When do I need to register for GST/QST?
As soon as your taxable supplies exceed $30,000 in a calendar quarter or over the four preceding calendar quarters. Below that, registration is optional, but it gives you the right to input tax credits and rebates — often worthwhile from the start in consulting services.
Is errors and omissions insurance mandatory?
Not by law for a consultant outside a professional order, but most large clients require it by contract: no policy, no mandate. Usual limits of $1M to $5M, solo premiums starting around $800 per year. Members of a professional order have mandatory insurance through their order.
How much does it cost to incorporate a consulting firm?
$397 in government fees, included in Incorp-Québec's Essential package at $497 all-in (articles of incorporation, initial declaration); the Complete package at $697 adds the official name, GST/QST and source deductions registrations, and express service.
