How to start a business in Canada as a US citizen: tax & setup guide

Written by  Andrew Coleman, CPA

Last updated May 31, 2026

A US citizen can fully own and run a business in Canada, but two tax systems apply from day one: the Canada Revenue Agency (CRA) on the Canadian side and the IRS on the US side, because the United States taxes citizens and green card holders on worldwide income.

This guide covers what to set up when you start a business in Canada from the US, including structure, CRA registration, tax rates, and the US foreign-corporation forms that follow.

Here are the most common questions upfront.

For the broader US picture, see our overview of US expat tax rules.

Can a US citizen start a business in Canada?

Yes. There is no Canadian citizenship or residency requirement to own a business at the federal level, and most provinces allow non-resident ownership.

The barrier is rarely ownership; it is the right to physically work in Canada. Owning shares in a Canadian corporation does not give you immigration status.

A US citizen starting a business in Canada who plans to relocate, perform paid work on Canadian soil, or take on a managerial role usually needs a work permit. Activities permitted under the business visitor category are narrow: meetings, contract negotiation, and after-sales service, but not active employment.

A useful separation to remember:

• Ownership of a Canadian company is usually permitted for any foreign national.
• Director residency rules depend on the statute. Under federal incorporation, corporations ordinarily need at least 25% resident Canadian directors, or at least one if there are fewer than four directors. Provincial rules still need a separate check.
• Working in Canada requires work authorization, separate from ownership.
• Banking typically requires in-person identification and a local address for business accounts.

A US business in Canada that is fully owned by a US citizen is therefore legal, but operational steps (banking, contracts, hiring) usually require local presence or a Canadian representative. Short trips for owners generally fall under standard visitor rules.

Quick checklist: how to start a business in Canada from the US

The full Canada business start-up process takes 1 to 4 weeks for a federally incorporated company, assuming name approval, banking, and CRA registrations move in parallel.

The same checklist applies whether you are an American starting a business in Canada through incorporation or planning to start a business in Canada as a non-resident. The 10 steps below cover everything from structure choice through your first US filing year:

1. Choose a structure. Sole proprietorship, partnership, corporation, or co-operative. Skip US LLCs (see structure section below).
2. Pick federal or provincial incorporation. Decide based on where you will operate and the director's residency rules.
3. Run a name search. NUANS report for federal; provincial systems for provincial.
4. Incorporate or register. File articles of incorporation, or register the sole proprietorship/partnership name.
5. Get a Business Number (BN). This is your CRA identifier for all federal accounts.
6. Open CRA program accounts. Corporate income tax (RC), GST/HST (RT), payroll (RP), import/export (RM), as needed.
7. Register for GST/HST. Mandatory once you cross the $30,000 small supplier threshold; optional below it.
8. Open a Canadian business bank account. Most banks require an in-person visit.
9. Set up bookkeeping in CAD. Track expenses in Canadian dollars; convert to USD for IRS filings.
10.  Plan your US filings. Form 5471, 8865, 8858, 8938, and FBAR may apply from year one.

The federal government lists the underlying registries and the order in which you usually need them.

As of November 3, 2025, new BN and CRA program account registrations are done online through Business Registration Online (BRO); phone registration is no longer available. If you cannot complete the registration online, you can submit the form by mail.

For complex cross-border setups, TFX works directly with founders doing business in Canada from the US, including dual filings, CFC analysis, and quarterly bookkeeping. Country-level guidance is collected on our Canada services page.

If your setup spans both countries, a cross-border tax professional can handle the dual filings and CFC analysis from year one.

Choose the right Canadian business structure

Canada recognizes four main structures: sole proprietorship, partnership, corporation, and co-operative.

The most important fact for Americans: Canada does not have LLCs or S-Corps. A US LLC operating in Canada is generally treated as a corporation by the CRA, which can break the pass-through treatment you assumed on the US side and trigger double tax.

The tax benefits of incorporating a business in Canada include limited liability, lower active-business tax rates, income-splitting flexibility (within TOSI rules), and easier access to certain credits.

The trade-off is more compliance: a separate T2 return, corporate bookkeeping, and CFC-level US filings on the IRS side.

For most US citizens planning to start a business in Canada as a foreigner, a Canadian corporation is the cleanest path, but it triggers full US foreign-corporation reporting through Form 5471. A sole proprietorship is simpler but exposes personal assets and is taxed at full personal rates.

For more on the US compliance layer, see our overview of US tax preparation in Canada.

Federal vs provincial incorporation in Canada

Federal incorporation gives you nationwide name protection and the right to operate under that name in every province, but you still need to register extra-provincially in each province where you carry on business.

Provincial incorporation is cheaper upfront, faster, and well-suited to businesses that operate in one province only.

The choice usually comes down to three factors:

• Where will you operate? One province only points to provincial. Multiple provinces or unclear future scope points to the federal.
• Director Residency. Under federal CBCA incorporation, at least 25% of directors must generally be resident Canadians, or at least one director if the corporation has fewer than four directors. Provincial rules vary and should be checked before incorporation.
• Local address. Most provinces require a registered office address (and sometimes an agent for service) in the province of incorporation.

Federal incorporation costs $200 online for those registering a federal corporation across provinces and territories, plus per-province extra-provincial registration fees. Provincial-only fees vary (Ontario is around $300, BC is around $350).

Registering your Canadian business with CRA

Every Canadian business that has employees, charges GST/HST, imports or exports, or files a corporate return needs a 9-digit Business Number (BN) from the CRA.

The BN is followed by a 2-letter program code and a 4-digit reference number to form each program account (for example, 123456789 RT 0001 for GST/HST).

You typically need one or more of the following CRA program accounts:

• RC: corporate income tax (automatic for incorporated businesses)
• RT: GST/HST
• RP: payroll deductions
• RM: import/export

Phone registration for a new BN or CRA program account is no longer available as of November 3, 2025. Use Business Registration Online (BRO) to register. If you cannot register online, you can submit the form by mail.

The most common Canadian business tax forms you will see:

• T2: corporation income tax return
• T1: personal return (covers sole proprietors and partners)
• T5013: partnership information return
• GST34: GST/HST return
• T4 / T4A: payroll information returns for employees and contractors

Canadian business income tax is calculated at both federal and provincial levels on the same T2, except in Quebec and Alberta, which administer their own corporate tax and require a separate provincial corporate return.

Canada business tax rates in 2026

The federal net Canada business tax rate is 15% on general active business income and 9% on the first $500,000 of qualifying CCPC income.

Provincial rates are added on top, generally between 0% and 16% depending on province and income type. The combined rate for a non-CCPC operating in a typical province usually falls between 23% and 31%.

For most US-owned Canadian corporations, expect the general federal rate of 15% plus a provincial rate of 8%–16%, because non-resident ownership generally blocks CCPC status and the 9% small business rate.

Ontario's general corporate rate is 11.5%. Its small business rate is 3.2% in early 2026, with a planned reduction to 2.2% from July 1, 2026.

Quebec and Alberta administer their own corporate tax outside the CRA, so you file a separate provincial return there. Current federal and provincial corporation tax rates are published by the CRA and updated annually.

The general framework for Canadian corporations, including who files a T2 and how rates apply, covers all of the above, plus reporting obligations for non-resident-owned corporations.

Small business deduction in Canada

The small business tax deduction in Canada brings the federal corporate rate from 15% down to 9% on the first $500,000 of active business income, but only for a Canadian-Controlled Private Corporation (CCPC).

The deduction grinds down to zero when taxable capital employed in Canada reaches $50 million, and a separate adjusted aggregate investment income test can also reduce or eliminate access.

A corporation generally qualifies as a CCPC if all of the following are true:

• It is a private corporation.
• It is a resident in Canada.
• It is not controlled, directly or indirectly, by non-residents, public corporations, or any combination of the two.

US ownership often triggers this problem, but the CCPC test looks beyond voting-share percentages: if a US citizen or any non-resident controls the corporation directly or indirectly, the company fails the CCPC test, loses the small business deduction, and pays the general 15% federal rate plus provincial.

The same risk applies to associated corporations: if your Canadian company is "associated" with another corporation you control, you share the $500,000 limit.

Canada business tax filing deadlines

The Canada business tax filing deadline for a T2 corporation return is six months after the end of the corporation's fiscal year.

Corporate tax owed is due earlier: two months after year-end for most corporations, or three months after year-end for CCPCs that meet specific income criteria.

Key dates to track for any Canada business tax return cycle:

• T2 corporate return: 6 months after fiscal year-end.
• Corporate tax balance: 2 months after year-end (3 months for qualifying CCPCs).
• Quarterly or monthly instalments: based on prior-year tax, typically required after the first profitable year.
• GST/HST return: monthly, quarterly, or annual, depending on revenue.
• Payroll remittances: monthly by default, more frequently as payroll grows.
• T4/T4A slips to CRA and employees: last day of February, or the next business day when February 28 falls on a weekend.

A Canadian corporation with a December 31 year-end therefore files its Canadian business tax return by June 30 of the following year and pays its balance by February 28 (or March 31 for qualifying CCPCs).

The CRA's corporation income tax return filing schedule confirms the six-month return deadline, and the full calendar of important dates for corporations lists balance, instalment, and information-return due dates side by side.

US filers should align the Canadian fiscal year-end with US planning, because mismatched year-ends create timing problems for Foreign Tax Credit claims on Form 1116 and complicate Form 5471 Subpart F or GILTI calculations.

We handle this coordination as part of our expat tax services.

GST/HST, payroll, and import/export accounts

GST/HST registration is mandatory once your business exceeds $30,000 in worldwide taxable supplies over four consecutive calendar quarters, or in a single calendar quarter.

Below that threshold, you are a "small supplier" and registration is optional, but voluntary registration lets you claim Input Tax Credits (ITCs) on business purchases through a GST/HST account.

Provincial sales tax rates in 2026:

• GST only (5%): Alberta, Yukon, Northwest Territories, and Nunavut.
• GST plus a separate provincial sales tax or QST: British Columbia, Saskatchewan, Manitoba, and Quebec.
• HST (combined federal + provincial): Ontario 13%, Nova Scotia 14%, New Brunswick 15%, Newfoundland and Labrador 15%, Prince Edward Island 15%.

A few practical rules:

• Register before your first taxable sale above $30,000. Late registration triggers retroactive GST/HST liability on past sales.
• Charge based on where the customer is, not where you are. Place-of-supply rules govern this.
• Some services supplied to non-resident customers can be zero-rated, but it depends on the specific service and recipient. Zero-rating is not automatic. You can still claim ITCs when it applies.

Payroll accounts (RP) are required before issuing the first paycheck. The employer remits federal and provincial income tax, Canada Pension Plan (CPP), and Employment Insurance (EI) on each pay run.

CPP contribution rates for 2026 are scheduled to remain at 5.95% employee and 5.95% employer up to the YMPE, plus the second-tier CPP2 between the YMPE and YAMPE.

Import/export accounts (RM) are required if you import goods commercially or export taxable goods. The account links to CBSA for customs declarations and duty calculations.

Tax deductions for small businesses in Canada

The CRA allows deduction of any current expense incurred for the purpose of earning income, which covers most ordinary business spending.

The list below shows the most common tax deductions for small businesses in Canada, all of which apply equally to sole proprietors filing on T1 and corporations filing on T2:

• Rent and utilities for business premises.
• Office supplies and software subscriptions.
• Salaries, wages, and benefits paid to employees, including CPP/EI employer portions.
• Professional fees (legal, accounting, consulting).
• Advertising and marketing, with limits on advertising in non-Canadian media for Canadian audiences.
• Vehicle expenses, prorated by business-use percentage.
• Home office expenses, prorated by square footage or room count, if the home is the principal place of business or used regularly for clients.
• Capital Cost Allowance (CCA) for depreciable assets: equipment, vehicles, buildings, and certain software.
• Meals and entertainment are generally limited to 50% deductibility.

Deductions vs credits:

• A deduction reduces taxable income. If your corporation is taxed at 26.5% combined, a $1,000 deduction saves $265.
• A credit reduces tax payable directly. A $1,000 non-refundable credit saves $1,000 in tax, assuming you owe at least that much.

Capital expenditures (assets that last more than a year) are not deducted in full in the year of purchase. You claim CCA over multiple years at a class-specific rate (for example, Class 50 computer equipment at 55%, Class 1 buildings at 4%).

Tax credits and incentives for Canadian businesses

Federal and provincial business tax credits in Canada target three main areas: research and development, hiring, and capital investment in priority sectors.

The biggest single program is the federal Scientific Research and Experimental Development (SR&ED) credit, which offers up to 35% refundable on the first $3 million of qualifying R&D spending for CCPCs and 15% non-refundable for other corporations.

Programs to know:

• SR&ED (federal): 35% refundable for CCPCs on the first $3 million; 15% non-refundable beyond that or for non-CCPCs. Most provinces add their own R&D credit.
• Investment Tax Credit (ITC): available for specific Atlantic-region and Northern Canada investments, certain clean energy property, and certain manufacturing.
• Apprenticeship Job Creation Credit: 10% of the eligible apprentice's salary, up to $2,000 per apprentice per year.
• Provincial digital media, film, and manufacturing credits: available in Ontario, British Columbia, Quebec, and elsewhere, with sector-specific rules.

For US-owned Canadian corporations, the SR&ED refundable rate is generally not available because CCPC status is lost. Non-refundable SR&ED at 15% is still claimable.

The federal SR&ED tax incentive program is administered by the CRA, and a fuller list of business tax credits covers Apprenticeship, ITC, and sector-specific options.

US tax rules for Americans who own a Canadian business

US citizens and green card holders report worldwide income to the IRS, full stop. Owning a Canadian business does not change that.

The US-Canada treaty reduces double taxation through the Foreign Tax Credit (Form 1116), but it does not exempt you from filing. Article XXIX(2) (the "saving clause") preserves the US right to tax its citizens as if the treaty did not exist.

For US citizens who own a business in Canada, the practical filing list usually includes:

• Form 1040 with worldwide income, including your share of the Canadian business.
• Form 5471 can apply in several categories. A 10% ownership threshold is one trigger in some cases, but it is not the only filing rule and does not capture every filing situation. Categories 1–5 dictate which schedules apply.
• Form 8865 if you are a partner in a foreign partnership.
• Form 8858 for foreign disregarded entities or foreign branches.
• Form 8938 if your specified foreign financial assets exceed the threshold ($200,000 end-of-year or $300,000 anytime, for single filers living abroad).
• FinCEN Form 114 (FBAR) if your aggregate foreign financial accounts exceed $10,000 at any point in the year. This includes business accounts you have signature authority over.

The two structural risks to flag:

• CFC status. A Controlled Foreign Corporation exists when US persons own more than 50% of a foreign corporation's vote or value. Subpart F income and GILTI (renamed NCTI under the One Big Beautiful Bill Act) inclusions can flow to your 1040 even if no cash is distributed.
• PFIC trap. Holding Canadian mutual funds or ETFs inside or outside a corporate structure can trigger Passive Foreign Investment Company rules, with punitive tax treatment under Section 1291.

For dual citizens, the picture is similar but with additional exit-tax exposure if renouncing. See our guide to US-Canada dual citizenship taxes.

US company doing business in Canada: when Canadian tax may apply

A US corporation doing business in Canada may still have Canadian filing obligations even without a permanent establishment. If it carries on business in Canada or disposes of taxable Canadian property, it generally must file a T2 return, even when treaty relief eliminates Canadian tax.

Without a PE, business profits are not taxed in Canada under Article VII, though a T2 filing may still be required.

A permanent establishment generally exists if any of the following are true:

• A fixed place of business in Canada: office, branch, factory, workshop, or similar.
• A dependent agent in Canada with authority to conclude contracts in the company's name and exercising that authority habitually.
• A construction or installation project in Canada lasting more than 12 months.
• Services performed in Canada for more than 183 days in any 12-month period for the same or connected project, under Article V(9).

The tax implications of doing business in Canada are still real, even with treaty protection. A US company without a PE may still need to:

• File a treaty-based T2 return to claim the exemption.
• Register for GST/HST if Canadian sales exceed $30,000. The threshold can apply to non-residents from the first dollar in some categories.
• Withhold Regulation 105 at 15% on payments to non-residents performing services in Canada. This is refundable through treaty if no PE exists.

A US company can do business in Canada as a US company without forming a Canadian subsidiary, but whether Canadian tax applies depends on whether it has a permanent establishment under the treaty. If it carries on business in Canada through a PE, Canadian tax and branch tax may apply, subject to treaty relief.

Canada-US tax treaty: business profits and permanent establishment

Article VII of the US-Canada tax treaty business profits rules allocates the right to tax business income to the country where the enterprise operates through a permanent establishment.

Article V defines what counts as a permanent establishment, and the 183-day services rule in Article V(9) is the most common trap for cross-border consultants and contractors. The complete US-Canada income tax treaty text is published by the IRS, with the consolidated protocols also available from the Department of Finance Canada treaty page.

The saving clause in Article XXIX(2) is critical for US citizens: it preserves the US right to tax its citizens on worldwide income, so most treaty benefits that would relieve a Canadian resident do not relieve a US citizen living in Canada. The Foreign Tax Credit, not treaty exemption, is the usual relief mechanism.

When you take a treaty position that reduces or eliminates US tax (for example, claiming no PE exists), you generally need to file Form 8833 with your US return to disclose the position. Disclosure is mandatory above $10,000 of treaty-based reduction; penalties for failure to disclose start at $1,000 for individuals and $10,000 for corporations.

The treaty also covers:

• Dividends: 5% withholding for corporate shareholders owning at least 10%; 15% otherwise.
• Interest: generally 0% if at arm's length.
• Royalties: 0%–10% depending on type.

Business immigration: Can you move to Canada to start a business?

Owning a Canadian business and being allowed to live and work in Canada are two separate questions.

Moving to Canada to start a business requires an immigration pathway: a work permit, a permanent residence stream, or a business visa program. Ownership alone gives you no right to enter Canada beyond the standard visitor allowance.

Routes used by US founders historically include:

• Start-Up Visa (SUV): permanent residence for entrepreneurs with a qualifying business and a designated organization's support.
• C11 entrepreneur work permit: for applicants who will own at least 50% of a Canadian business and can show significant economic benefit.
• Intra-Company Transferee (ICT): for executives, managers, and specialized-knowledge employees of a foreign parent opening a Canadian branch or subsidiary.
• CUSMA Investor / Trader: under the Canada-US-Mexico Agreement, for US citizens making substantial investments.

Important 2026 update on Canada's Start-Up Visa for business founders

As of January 1, 2026, the Start-Up Visa Program is paused for new applicants. Applicants with a valid 2025 commitment certificate can still apply until June 30, 2026.

A short-term business visa to Canada from the US is usually unnecessary, since US citizens are visa-exempt and can enter as business visitors for meetings, contract negotiation, and after-sales service. Anything beyond that, including hands-on work, requires a work permit.

For relocation planning, see how to move to Canada and the best places to live in Canada for US expats.

Best places to start a business in Canada

The best place to start a business in Canada depends on your customers, sales tax exposure, director residency requirements, and where work is physically performed. There is no single answer, but four provinces handle the majority of US-founded businesses.

• Ontario: largest market, deepest professional services bench, HST at 13%, no resident-director requirement since 2021. Combined corporate rate 26.5% general. Ontario's lower rate is 3.2% through June 30, 2026, then 2.2% from July 1, 2026.
• British Columbia: Pacific gateway, strong tech and film sectors, PST + GST (not HST), no resident-director requirement. Combined corporate rate 27% general.
• Alberta: lowest combined corporate rate at 23% general, no provincial sales tax, no resident-director requirement. Strong energy and ag-tech focus.
• Quebec: civil law jurisdiction (different from common-law provinces), French-language requirements for business operations, distinct corporate tax administration through Revenu Québec.

An easy business to start in Canada for a non-resident is generally one that:

• Does not require physical presence in Canada (consulting, SaaS, online services).
• Does not require a federally regulated license (banking, telecom, transport).
• Stays below the $30,000 GST/HST threshold initially while testing the market.

That said, "easy to start" is not the same as "easy to run cross-border." Even a one-person consulting setup will trigger Form 5471 or Form 8858 the moment it incorporates in Canada.

Sector-specific licensing varies by industry: founders in regulated areas should check the federal permits and licenses lookup tool, which also pulls in provincial and municipal requirements.

Canada vs US business taxes: Key differences

Canadian and US business tax systems share common ground (federal plus state/provincial layering, depreciation regimes, employment taxes) but diverge on structure recognition, sales tax, and capital gains.

The most consequential difference for founders running a Canada-US business is that Canada has no LLC or S-corp, so US pass-through plans rarely survive crossing the border intact.

For a US founder, the biggest structural shift in business in Canada vs the US is the absence of pass-through entities, the presence of a federal value-added tax (GST/HST), and the requirement to file in both countries every year because of US citizenship-based taxation.

Business capital gains tax in Canada is calculated using the one-half inclusion rate for tax year 2025. The proposed increase to two-thirds was later cancelled, so the one-half inclusion rate remains the current rule in the CRA's 2026 guidance.

Common mistakes US founders make in Canada

These are the seven mistakes that come up most often in TFX cross-border engagements and that drive the largest corrective bills.

1. Assuming a US LLC works the same way in Canada. The CRA treats US LLCs as corporations, breaking pass-through and creating double tax. The US owner still gets pass-through on the US side, so foreign tax credits are mismatched.
2. Missing GST/HST registration. Crossing $30,000 without registering triggers retroactive GST/HST liability on past sales. The CRA does not waive this when discovered.
3. Using personal bank accounts for business income and expenses. This breaks corporate veil arguments and creates bookkeeping chaos that can disqualify expense deductions.
4. Ignoring Form 5471, 8865, 8858, 8938, or FBAR. The Form 5471 penalty generally starts at $10,000 per failure and can rise by up to $50,000 in continuation penalties, for a potential total of $60,000 per form. The BSA E-Filing System is where the FBAR (FinCEN 114) is submitted. For 2026, a non-willful FBAR violation can trigger a penalty of up to $16,536, generally applied per FBAR form rather than per account after Bittner.
5. Assuming the treaty removes the US filing. It does not. The saving clause preserves US taxation of citizens, and treaty positions usually require disclosure on Form 8833.
6. Confusing business visitor status with work authorization. Closing deals, signing contracts, and attending meetings are visitor activities. Performing the work, even for a Canadian company you own, requires a work permit.
7. Year-end mismatches between the Canadian fiscal year and the US tax year. This creates timing problems for Foreign Tax Credit claims and Form 5471 calculations.
