How to Register a US Business from Canada

Overview

Canadian founders are, on paper, the best-positioned non-resident entrepreneurs in the world when it comes to entering the United States. Same time zones. Same language of commerce. A land border that carries roughly two billion dollars of trade a day. And yet the question we hear most often from Toronto, Vancouver and Calgary is not "should we expand?" but "how do we register a US business without accidentally creating a tax mess at home?"

That second half of the question is the one that matters. Registering a company in Delaware or Wyoming takes a few business days and costs less than a nice dinner. Registering the wrong company, in the wrong state, with the wrong tax election, and then discovering eighteen months later that the Canada Revenue Agency treats your structure differently than the IRS does — that is the expensive part. This Doc walks the entire path in order, with the Canadian-specific traps flagged where they actually appear.

Who This Doc Is For

You are a Canadian resident (citizen or PR) who wants a US legal entity. You are not relocating. You do not have a Social Security Number. You want US payment processing, US customers, US contracts, and ideally a US bank account, and you want to know exactly what each step costs and how long it takes before you start.

Step 1: Decide Whether You Actually Need a US Entity

Not every Canadian business needs one. If you sell digital services to a handful of US clients and invoice them from your Ontario corporation, you can often carry on for years without a US entity. The threshold questions are practical rather than legal:

• Do US customers refuse to onboard a foreign vendor? Enterprise procurement teams frequently do. A US EIN and a US address make you a domestic supplier in their system.
• Do you need US payment rails? Stripe, PayPal and Shopify Payments all support Canada, but US-domiciled accounts settle faster, cost less on cross-border card fees, and avoid FX haircuts on every transaction.
• Are you raising from US investors? American venture funds are structurally allergic to foreign entities. A Delaware C-Corp is not a preference, it is a precondition.
• Are you holding inventory in US warehouses? Amazon FBA stock in a US fulfilment centre creates state-level nexus regardless of where your company is registered. A US entity makes the sales tax registrations far cleaner.

If none of these apply, keep your Canadian corporation and revisit in six months. If any two apply, keep reading.

Step 2: LLC or C-Corporation — The Canadian Wrinkle

This is where generic advice hurts Canadians specifically, so read this section twice.

A US LLC is a pass-through entity for US federal purposes. Profits flow to the owner and are taxed once. For a founder in most countries, that is the efficient choice. Canada is the notable exception. The CRA generally treats a US LLC as a corporation for Canadian tax purposes, while the IRS treats it as a flow-through. That mismatch is a classic hybrid-entity problem: income can be taxed personally in the US and again as a dividend in Canada, and foreign tax credits may not line up cleanly. Canada–US treaty relief exists, but it is narrow and fact-specific.

Practical translation:

• Canadian resident, service business, wants simplicity: an LLC still works for many founders, but you should confirm the treatment with a cross-border accountant before you file, not after. Do not assume the flow-through benefit reaches you.
• Canadian resident planning to raise capital or issue equity: a Delaware C-Corporation is almost always the answer. It is a corporation on both sides of the border, so the classification mismatch disappears, and Canadian tax treatment of dividends and share sales is well-trodden ground.
• Canadian corporation expanding operations: many groups register a US C-Corp as a subsidiary of the existing Canadian corporation, keeping ownership at the corporate level rather than the personal level.

If you are unsure which fits, our comparison of LLC, S-Corp and C-Corp structures lays out the trade-offs, and Bizvee's formation team will not file until the structure question is settled.

Step 3: Choose Your State

Three states account for the overwhelming majority of non-resident registrations, and they are not interchangeable.

Delaware is the default for anything venture-backed. Its Court of Chancery has two centuries of corporate case law, investors' documents assume it, and no serious US fund will ask you to justify the choice. Costs run higher: an annual franchise tax plus a registered agent fee.

Wyoming is the cost-efficient favourite for LLCs. Low annual report fees, strong charging-order protection, no state income tax, and minimal public disclosure of members. For a bootstrapped services business or an ecommerce brand, it is hard to beat.

Florida, Texas or New York make sense only if you have genuine physical operations there — staff, an office, inventory you control. Registering in a state where you actually operate avoids the need to also register as a "foreign entity" in that state later.

Do not chase a state because a blog called it "tax free." If you have employees or a warehouse in California, California will find you regardless of where the certificate was issued. Our US state filing and renewal fee explorer shows the real year-one and year-two cost of each state so you can compare like for like.

Step 4: File the Formation Documents

Formation itself is administrative. You will need:

• A company name that is available in your chosen state and does not include restricted words such as "bank," "insurance" or "trust" without a licence.
• A registered agent with a physical street address in the state, available during business hours to receive legal service. You cannot use your Vancouver address for this. Bizvee's US registered agent service covers this at $49/year.
• A US business address for banking, platform verification and correspondence. A registered agent address is not the same thing and is often rejected by banks. Our US physical business address is $149/year and includes mail scanning.
• Member or director details, which vary in how public they are by state.

Turnaround is typically one to five business days depending on state and whether you pay for expedited processing.

Step 5: Get an EIN Without an SSN

The Employer Identification Number is the federal tax ID for the company. It is free from the IRS, and it is the single step where Canadian founders lose the most time.

The instant online EIN application requires the responsible party to hold an SSN or ITIN. Without one, you file Form SS-4 by fax or mail. Realistic timelines: fax responses often return in two to four weeks; mail can take four to eight. Rejections are common and usually caused by small errors — an entity name that does not exactly match the state filing, a missing responsible-party signature, a formation date that predates the certificate, or a foreign address formatted in a way the IRS system will not accept.

Two important clarifications:

1. You do not need an ITIN to get an EIN. Write "Foreign" in the SSN field of the SS-4. Applications get delayed constantly because founders think they must obtain a personal number first.
2. You may need an ITIN later — for a personal US filing obligation, a treaty claim, or reduced withholding. Handle that separately once the company exists. Bizvee runs both as distinct services: EIN application and ITIN application.

Step 6: Open US Banking

You have your certificate, your EIN letter (CP 575) and your operating agreement or bylaws. Now the bank.

Traditional US banks generally require an in-person visit by a signatory. That is feasible for Canadians — a day trip to Buffalo or Bellingham is a real strategy people use — but it is not required. Fintech banking platforms built for startups onboard non-resident founders remotely and are what most Bizvee clients use. Expect to provide:

• Certificate of Formation or Incorporation
• EIN confirmation letter
• Operating agreement (LLC) or bylaws plus a banking resolution (Corp)
• Passport of each beneficial owner
• Proof of home address
• A clear description of the business, its customers and expected monthly volume

The last item causes more rejections than any document. "Consulting" is not a business description. "Monthly retainer software development for four US SaaS companies, invoiced in USD, expected volume $30–50k/month" is. Our banking support guide covers the platforms that reliably accept Canadian founders and what each one asks for.

Step 7: Understand Your Two-Country Tax Picture

Here is the honest version, stripped of comfort.

US federal. A C-Corp files Form 1120 annually and pays 21% federal tax on US taxable income. A foreign-owned single-member LLC files Form 5472 with a pro-forma 1120 every year even with zero income — the penalty for missing it is $25,000, and it is applied mechanically.

US state. Franchise taxes and annual reports are separate from income tax and are due regardless of profit. Delaware and Wyoming both have annual obligations.

Sales tax. Economic nexus rules mean you may owe sales tax in states where you have no physical presence at all, triggered purely by revenue or transaction thresholds. Ecommerce sellers hit this fastest. See our sales tax registration service.

Canada. Your Canadian corporation or personal return still reports worldwide income. Foreign affiliate reporting (T1134), foreign property reporting (T1135) and transfer pricing between your Canadian and US entities all come into play once the structure is live. Intercompany invoicing between your two companies must be at arm's-length rates and documented.

Permanent establishment. If you manage the US company entirely from Canada, the treaty may treat it as having a Canadian permanent establishment. This is a technical determination, not a matter of opinion, and it is the reason cross-border advice is worth paying for once.

Step 8: Build the Annual Compliance Calendar

Formation is a day. Compliance is forever. Set these before you forget them:

Bizvee clients get these tracked in the dashboard with reminders, and our bookkeeping and tax filing services handle the US side end to end.

Common Mistakes Canadian Founders Make

Forming an LLC because a US podcast said so. The hybrid-entity issue is real and Canada-specific. Confirm first.

Using a home Canadian address on the US filing. It works for the state and then fails at the bank, at Stripe, and at the platform onboarding stage.

Skipping the operating agreement. Banks ask for it, partners rely on it, and courts look at it when the relationship goes wrong. Generate one free with our operating agreement tool.

Assuming the EIN arrives quickly. Build four to eight weeks into your launch plan or pay for a service that handles the follow-up with the IRS.

Ignoring Form 5472. It is the most expensive piece of paper a non-resident LLC owner can forget.

Timeline at a Glance

• Days 1–2: structure decision and name check
• Days 2–5: state filing, registered agent, business address
• Weeks 1–6: EIN via SS-4
• Weeks 6–8: bank account and payment processors
• Ongoing: bookkeeping from day one, not from March

Where Bizvee Fits

We file the entity, act as registered agent, provide the US business address, chase the IRS for your EIN, prepare the operating agreement or bylaws, introduce you to banking partners who accept Canadian founders, and keep the compliance calendar so nothing lapses. Start with company formation, or book a founder consultation if the LLC-versus-C-Corp decision is still open — for Canadians, that one conversation is usually worth more than everything else on this page.
