The Structural Decision: C-Corp vs. LLC vs. S-Corp

Most Canadian founders go wrong with the selection of the right entity type for their business. Don't just choose the entity based on the setup fees. Instead you need to assess the choices based on your capital strategy.

If you intend to raise venture capital from investors, a Delaware C-Corp is the standard. Investors require it for equity grants and preferred stock structures. If you are running a bootstrapped SaaS, an agency, or a services business, a Wyoming LLC is often more efficient due to lower fees and no state corporate income tax.

There is one important nuance for Canadian founders. Canadian tax authorities treat US LLCs as corporations for Canadian tax purposes, not as pass-through entities. This mismatch (LLC is pass-through in the USA, corporation in Canada) can create double-taxation situations. Many Canadian founders end up preferring the C-Corp structure specifically because the tax classification is consistent on both sides of the border.

Some Canadian founders read about the "tax savings" of an S-Corp and try to elect this status. This is not allowed. To get S-Corporation status you need to strictly be a US person. As a Canadian resident you are not legally eligible to own shares in an S-Corp.

Prerequisites for Canadian Founders

Before you file your articles of incorporation, you must have these four pillars in place. Missing one will stall your banking or trigger immediate IRS notices.

• Unique Company Name: Must be distinguishable from existing entities in your chosen state.
• Registered Agent: A person or service with a physical street address in the state of incorporation.
• USA Business Address: While you don't need to live in the USA, banks and the IRS require a USA-based mailing address for KYC (Know Your Customer) requirements.
• Founder Documentation: Valid Canadian passports for all directors and shareholders/members.

Documents required to start a USA Company

These are the documents US banks and the IRS will typically request from a Canadian founder during formation and account opening. Home-country regulatory processes (if any apply on the Canada side to owning a foreign entity) fall outside the scope of this guide. Consult a Canadian cross-border adviser for those.

• Canadian Passport: Primary identity document for all directors and shareholders. US banks require a valid international passport for every beneficial owner (25%+ ownership).
• Proof of Address: A recent utility bill, bank statement, or government-issued document showing your current residential address. US banks use this to verify residency and geolocation consistency.
• Source-of-Funds Documentation: US banks routinely ask for evidence of legitimate source when funding comes from outside the USA. Salary slips, business income records, or investment statements typically satisfy this.
• Business Plan (optional but helpful): A short business plan meaningfully accelerates US bank account applications for founders from any jurisdiction.
• Corporate Records (if using a parent entity): If your existing home-country company will own the US entity, US banks will require formal corporate records (incorporation certificate, authorization resolutions, beneficial ownership disclosure) for KYC. If those records are in a language other than English, US banks will typically request certified translations.

Step-by-Step Registration Process

Select Your State: Delaware or Wyoming or any other state.

1. Appoint a Registered Agent: Hire a professional service to handle state correspondence.
2. File Articles of Organization/Incorporation: The formal filing with the Secretary of State.
3. Obtain an EIN (Tax ID): File Form SS-4 with the IRS via fax. As a Canadian resident, expect 4 to 6 weeks for EIN processing.
4. Open a USA Bank Account: Use your EIN to apply for a business account through platforms like Mercury, Relay, and Meow. Canadians typically clear onboarding in 1 to 2 weeks and are among the easiest applicants for US fintechs.

The Cost of Doing Business

• State Filing Fees: $90–$200.
• Registered Agent: $100–$300 annually.
• Franchise Tax: Minimum $175 for LLCs; $175+ for C-Corps.
• Compliance & Tax Prep: $1,000–$2,500 annually for foreign-owner reporting (e.g., Form 5472).

Challenges for Canadian Founders

These are the challenges Canadian founders specifically face on the USA side of setting up a US business. Tax and regulatory implications on the Canada side of owning a US entity fall outside our scope of expertise. If you need advice on how income from your US company is taxed in Canada, or on any Canada reporting obligations, consult a Canada cross-border tax adviser.

• US EIN Processing Timeline: As a Canadian resident, expect 4 to 6 weeks for EIN acquisition via fax. Standard timeline for founders from lower-risk jurisdictions.
• US Bank Account Onboarding: Expect 1 to 2 weeks for US bank account activation. Canadians are treated near-US-person by most US fintechs. Fastest US bank onboarding of any foreign-founder nationality.
• US-Canada Tax Treaty Benefits: One of the most comprehensive treaties the USA has with any country. Dividend withholding is reduced to 5% for corporate shareholders with 10%+ ownership, 15% otherwise. Interest and royalty withholding is also reduced.
• Form W-8BEN: File Form W-8BEN with your US bank and any US paying agent to claim treaty benefits.
• US Entity Choice Implications: Your choice of Delaware C-Corp vs Wyoming LLC (or any other US entity) affects how the US entity is taxed in the USA. The interaction with Canada-side tax treatment is a cross-border question worth discussing with a Canada tax adviser familiar with US structures.

Comparison: LLC vs. C-Corp vs. S-Corp

FAQs

Why can't I use an S-Corp as a Canadian founder? The IRS mandates that S-Corp shareholders must be "US persons." Attempting this structure will lead to the company being taxed as a C-Corp by default, often with late-filing penalties.

Does the US-Canada tax treaty apply to my US company income? Yes. Canada has a comprehensive tax treaty with the USA that reduces US withholding rates on dividends, interest, and royalties from your US entity. File Form W-8BEN with your US bank and any US paying agent to claim treaty benefits. For the tax implications on the Canada side, consult a Canada cross-border tax adviser.

Do I need USA Visa or Social Security Number as a Canadian resident to incorporate my company in USA? You do NOT need a US Visa or a Social Security Number (SSN) to own a US company.

How long does the whole US-side process take from Canada? State registration takes 2 to 5 days. EIN acquisition for Canadian residents typically takes 4 to 6 weeks via fax. US bank account activation adds another 1 to 2 weeks.

What about my tax obligations in Canada? That falls outside our scope of expertise. Owning a US entity may create reporting or tax obligations on the Canada side. Consult a Canada cross-border tax adviser for how your US company income is treated locally.
