Who this guide is for
Anyone in Canada about to turn an idea into income and stuck on the very first fork: register as a sole proprietor, or incorporate.
That includes freelancers and consultants taking their first client, side-business owners deciding whether to "make it official," tradespeople and creators starting to earn, and newcomers building a business in a system they're learning from scratch. You don't need to have decided on a name, a niche, or a plan. You only need to be close enough that the structure question has become real.
It does not replace advice from an accountant or lawyer about your own numbers — and by the end you'll see exactly where that line is, and when crossing it is worth the money.
Most new founders should start as a sole proprietor — and incorporate when there's a reason to.
If you're testing an idea, earning modestly, carrying little liability, and you need the income to live on, a sole proprietorship is usually right: it's cheap, it's simple, and — this surprises people — your tax bill is often roughly the same as a corporation's once the rules are accounted for.
Incorporate when you have a specific problem it solves: real liability exposure, consistent profit you can leave inside the company, investors or clients who require it, or an eventual sale. A corporation is a powerful tool with ongoing cost and paperwork. It should answer a problem you actually have — not one you imagine you might have someday.
What you're actually choosing between
Strip away the jargon and there's one idea underneath everything else.
A sole proprietorship is you. There is no separate entity. You earn the income, you owe the tax, you carry the risk, all personally. Registering a sole proprietorship mostly means registering a name to operate under — it doesn't create a new legal "thing."
A corporation is a separate legal person. Once created, it exists apart from you. It earns its own income, owns its own assets, signs its own contracts, files its own tax return, and can be sued in its own name. You own and run it — but you and it are legally two different parties.
Almost every practical difference below — liability, tax, banking, paperwork — flows from that one distinction.
Sole Proprietorship
You, operating a business under your own name or a registered business name.
- Legally
- Not separate from you. You are the business.
- Liability
- Unlimited — personal assets are exposed.
- Tax filing
- On your personal return (T1) using form T2125.
- Setup
- Fast and cheap; often same-day online.
- Upkeep
- Minimal. No separate corporate filings.
Corporation
A separate company you own and direct, distinct from you in law.
- Legally
- A separate legal person, distinct from its owner.
- Liability
- Limited — with real exceptions (see below).
- Tax filing
- Its own corporate return (T2), separate from you.
- Setup
- More steps, more cost, name & share structure.
- Upkeep
- Ongoing: minute book, annual return, T2, records.
Liability: the difference that actually protects you (with caveats)
This is the reason many founders incorporate, and it's a real one. As a sole proprietor, if the business is sued or can't pay a debt, your personal assets — savings, and in some cases your home — are on the table, because there's no legal line between you and the business.
A corporation draws that line. In general, the company's debts and liabilities are the company's, not yours, so a creditor or claimant reaches the corporation's assets, not your personal ones. That protection is the "corporate veil."
Three things routinely pierce it for small founders, and no one mentions them at the registry counter:
- Personal guarantees. Banks, landlords, and major suppliers often won't extend credit to a young corporation without you personally guaranteeing it. Sign that, and you've contracted around your own protection for that debt.
- Director liabilities. Directors can be held personally liable for specific things even inside a corporation — most importantly unremitted GST/HST and payroll source deductions, and unpaid wages in some cases.
- Your own conduct. Fraud, negligence, or personal wrongdoing isn't shielded by incorporating.
The veil is genuinely valuable — especially if you have employees, premises, physical products, or significant contracts. Just don't treat it as absolute, and don't incorporate only for liability if your real risk is low.
Tax: the most misunderstood reason people incorporate
"Incorporate to save tax" is the most repeated advice in Canadian business — and for a lot of new founders, it's simply wrong. Here's what's actually true.
A sole proprietor's business income is added to their personal income and taxed at personal marginal rates. Nothing separates it.
A corporation that qualifies as a Canadian-Controlled Private Corporation (CCPC) pays a low rate on its first slice of active business income through the small business deduction: 9% federally on the first $500,000 of active business income, versus the general federal rate of 15%. Add the provincial small-business rate and the combined rate lands around 9–13% depending on the province.
That looks like an enormous saving. The catch is what happens next.
That low corporate rate applies to money kept inside the company. The moment you pay it to yourself — as salary or dividends — you pay personal tax on it too. Canada's tax system is built around "integration," which means the combined corporate-then-personal tax you pay roughly equals what you'd have paid as a sole proprietor. The corporate rate isn't a permanent break; it's a deferral on profit you don't need yet.
So the real tax advantage of incorporating shows up only when you can afford to leave profit in the company to reinvest or invest. If you need every dollar the business earns to live on, incorporating usually saves little or no tax — while adding real cost and paperwork.
Two more things before you assume incorporation = savings
- The small business rate has conditions. The 9% rate requires CCPC status and active business income; it grinds down when a corporation earns more than $50,000 of passive investment income in a year, and disappears entirely by about $150,000 of passive income.
- Income splitting is restricted now. Paying family members to lower the household tax bill was a classic corporate move, but the "tax on split income" (TOSI) rules since 2018 sharply limit it unless those family members are genuinely, actively involved in the business.
There are real long-game tax advantages — a lifetime capital gains exemption (over $1 million) can shelter much of the gain when you sell qualifying small-business-corporation shares, and deferral compounds over years. They're just advantages for a specific situation, not a default everyone should grab on day one.
One simple rule for when to get help: once the business is producing consistent profit beyond what you need to live on, that is the moment to run the numbers with a CPA.
GST/HST: this is about revenue, not structure
A common myth is that incorporating triggers sales-tax obligations, or that sole proprietors don't deal with GST/HST. Both are wrong. The rule is the same for either structure, and it's tied to one number.
You must register for GST/HST once your taxable revenue passes the small-supplier threshold of $30,000 — measured over a single calendar quarter, or over four consecutive calendar quarters. Cross it in one quarter and you have to register essentially immediately (within 29 days), and start charging tax on the very sale that put you over. This threshold is not indexed to inflation, and it counts taxable revenue — not employment income or exempt supplies.
- Below $30,000? You're a "small supplier" and registration is optional. You can still register voluntarily — worth it if you have big startup expenses, because it lets you claim input tax credits (refunds of the GST/HST you paid on business purchases).
- Whichever structure you pick, the threshold is identical. Incorporating doesn't change when you owe sales tax.
CRA directs new businesses to register GST/HST accounts online through Business Registration Online. Before relying on phone or paper registration, check CRA’s current GST/HST registration page.
The business bank account
Here the structures genuinely differ.
As a sole proprietor, the law doesn't force you to have a separate business account — but you should open one anyway, and you'll generally need one once you operate under a registered business name (the bank wants the account name to match). Mixing business and personal money makes bookkeeping and tax time miserable.
A corporation must have its own bank account. Because it's a separate legal person, its money is not your money. Running corporate income through a personal account isn't just messy — it undermines the very separation (the corporate veil) you incorporated to get. Keep corporate and personal finances strictly apart.
CRA accounts: the Business Number and what hangs off it
Both structures live under one root identifier: the Business Number (BN), a single number the CRA uses to track your business. Specific program accounts attach to that BN as you need them:
- RT — GST/HST, once you register (mandatory past $30,000, optional before).
- RP — Payroll, once you hire and start paying employees and remitting source deductions.
- RC — Corporate income tax, for corporations only — this is the account a corporation files its T2 against.
The clean way to see it: a sole proprietor has a BN and may add GST/HST and payroll accounts, but files business income on their personal T1 (via T2125) — no corporate tax account. A corporation has a BN with a corporate income tax account and files its own T2, plus GST/HST and payroll accounts as needed.
What each one really costs — in money and in time
The registry fee is the small part. The ongoing burden is the part founders underestimate.
Sole proprietorship
- Setup: a modest provincial registration (often well under $100), frequently same-day online. In some provinces, operating strictly under your own legal name needs no registration at all.
- Ongoing: file your taxes once a year on your personal return. No separate corporate filings, no minute book, no annual corporate return.
Corporation
- Setup (government): federal incorporation through Corporations Canada is $200 online ($250 by paper); provincial incorporation fees vary (roughly $300–$360 in the larger provinces), usually plus a name-approval fee.
- Setup (real-world): most founders also pay for legal/accounting help to set up the share structure and minute book properly — commonly several hundred to a couple of thousand dollars. It's optional, but mistakes here are expensive to unwind.
- Ongoing: a separate T2 corporate return every year (most owners hire an accountant — budget meaningful annual fees), an annual corporate return to the registry, a maintained minute book, and, for federal corporations, an Individuals with Significant Control (ISC) register.
- Federal-specific: a federal corporation still has to register extra-provincially in each province where it actually does business — an extra filing and an extra annual fee per province.
Federal incorporation gives nationwide name protection and easy interprovincial reach, but costs more once you layer in extra-provincial registrations, and carries a director-residency rule (next section). Provincial incorporation is usually cheaper and simpler if you operate in one province — with name protection limited to that province. For many single-province small businesses, provincial is the practical pick.
So which one — for you, right now?
Match your situation, not your ambition. You can always incorporate later; many founders do exactly that once the business proves itself.
Stay a sole proprietor if…
- You're testing an idea or running a side business
- Revenue is modest and your liability risk is low
- You're a freelancer or consultant working on your own
- You need most of the income to live on (so deferral wouldn't help)
- You value simplicity and low cost right now
Incorporate if…
- You have real liability exposure — employees, premises, products, big contracts
- You're consistently profitable beyond what you draw, and can leave money in
- You're planning to hire, scale, or raise investment
- Clients, institutions, or government require you to be incorporated
- You're building toward an eventual sale of the business
If you're an immigrant founder
Two things trip up newcomers constantly — and getting them wrong is costly, so they're worth stating plainly.
You generally do not need to be a citizen or permanent resident to register a sole proprietorship or incorporate a company in Canada. But your immigration status governs whether you can actively work in and run that business inside Canada. Owning shares passively is one thing; being self-employed and operating day-to-day is another, and some permits restrict it. Confirm what your specific status allows with IRCC or an immigration professional before you start operating — the registry will happily register you regardless of whether you're authorized to work.
The federal director-residency rule (verified, and it still applies)
If you incorporate federally, the Canada Business Corporations Act requires that at least 25% of the directors be "resident Canadians" — and if there are fewer than four directors, at least one must be. A "resident Canadian" means a citizen ordinarily resident in Canada, or a permanent resident who has been ordinarily resident in Canada for more than one year. A brand-new PR or a non-resident doesn't satisfy this on their own.
This is exactly why many newcomer and non-resident founders incorporate provincially instead: several provinces — including British Columbia, Ontario, and Alberta — have no director-residency requirement at all. (Provinces removed theirs; the federal rule was not removed.)
One more nuance that matters for the tax section above: the low small-business rate requires CCPC status, which means the corporation must not be controlled by non-residents. If you're a resident controlling your own company, you're fine. A corporation controlled by non-residents generally loses the small business deduction.
If you're in British Columbia
The principles above are national; the mechanics and a few numbers are provincial. For B.C. specifically:
- Sole proprietorship: register through BC Registries / OneStop — about $40, typically same-day online. You'll first reserve a business name (about $30) unless you operate strictly under your own legal name, in which case registration may not be required. You log in with a BCeID or BC Services Card.
- Provincial incorporation: about $350 plus a $30 name-approval fee, through BC's corporate registry. B.C. has no director-residency requirement — a practical reason newcomers and non-residents often choose a B.C. corporation over a federal one (you still need a B.C. registered-office address).
- Corporate tax rate: a B.C. small business (CCPC) pays roughly 11% combined — 9% federal + 2% B.C. — on the first $500,000 of active business income; the general combined rate is about 27% (15% + 12%).
- PST is separate from GST. B.C. is not an HST province. On top of the federal GST, if you sell goods (and certain services) in B.C. you may need to register for and collect provincial sales tax (PST) — a separate registration from GST/HST.
- Municipal licence: most B.C. municipalities (Vancouver, Surrey, Victoria, and others) require a municipal business licence in addition to provincial registration. Check your city.

Common mistakes to avoid
- Incorporating too early "to save tax" when you need all the income to live on — paying for complexity that delivers no deferral benefit yet.
- Treating limited liability as absolute — forgetting personal guarantees and director liabilities for unremitted GST/HST and payroll.
- Commingling personal and corporate money — which weakens the corporate veil and turns bookkeeping into a nightmare.
- Assuming incorporation handles sales tax — the $30,000 GST/HST threshold is the same regardless of structure.
- Forgetting extra-provincial registration for a federal corporation that operates in a province.
- Choosing federal incorporation without realizing the 25% Canadian-resident director rule — when a provincial corporation would have avoided it.
- Assuming business registration grants the right to work in Canada — it doesn't; immigration status is a separate question.
