Canadian SaaS founders, agencies, and freelancers sometimes want a US LLC for US customers, Stripe, and a US-facing brand. But unlike most countries on this site, the LLC choice in Canada is not automatically the best move. The cross-border tax mismatch (below) means many Canadian founders are better served by a Canadian corporation or a US C-corp depending on goals. Treat the entity decision as something to get advised on first.

This is the point that matters most and that generic guides miss. The US generally treats a single-member LLC as a disregarded/pass-through entity, but the Canada Revenue Agency (CRA) has historically treated a US LLC as a corporation. That difference in classification can break the way treaty relief and foreign tax credits are supposed to work, and can create double taxation for a Canadian resident. NEEDS EXPERT REVIEW. Confirm with a US-Canada cross-border CPA before forming, and ask specifically whether an LLC, a Canadian corporation, or a US C-corp fits your situation.

Passport or government ID, proof of address, and LLC formation documents + EIN for banking/Stripe. Providers may request additional KYC.

File SS-4 with "Foreign" on line 7b; apply by fax or the international phone line (+1 267-941-1099). See the EIN guide. Timing varies; not guaranteed.

Mercury is generally available (verify at application); Wise Business and Payoneer also work for USD. No provider approval is guaranteed.

Stripe operates in Canada directly, so a Canadian founder may not even need a US entity to use Stripe, another reason to confirm whether a US LLC is the right tool for your goal before forming one. A US LLC + EIN can still help for US-specific needs, but approval is never guaranteed. See the Stripe guide.

On the US side, budget for Form 5472 + pro-forma 1120 every year plus your state report/fee; BOI does not apply to your US-formed LLC. On the Canadian side, GST/HST and CRA foreign-reporting obligations may apply. Confirm with your cross-border CPA.

Formation plus registered agent in USD, and the ongoing state cost depends on the state. Wyoming charges an annual report license tax of $60 or two-tenths of one mill on the dollar of assets located in Wyoming, whichever is greater, due the first day of the anniversary month of formation.[1]Wyoming Secretary of State, Annual Report and License Tax Rules Every domestic and foreign Delaware LLC owes a flat $400 annual tax, due on or before June 1, and files no annual report.[2]State of Delaware, Delaware Code, 6 Del.

The US LLC is easy to form and bank, but for a Canadian resident the tax treatment is the catch. Get a US-Canada cross-border CPA to confirm whether an LLC actually works for you (vs a Canadian corporation or US C-corp) before you form anything. If you do use a US LLC, file Form 5472 each year and handle GST/HST and CRA reporting properly.

CRA: Canada Revenue Agency. Entity classification mismatch. When two countries treat the same entity differently (e.g. US pass-through vs Canadian corporation). GST/HST. Canadian sales taxes. EIN / Form 5472 / ECI, see the federal guides.
