Moving to Canada With a US LLC: Why the Structure That Worked at Home Double-Taxes You Abroad

The LLC problem is a characterization problem. The US, by default, ignores a single-member LLC and taxes a multi-member LLC as a partnership: profits land on the owners' 1040s as earned, whether or not distributed. Canada looks at the same entity — limited liability, separate legal personality — and classifies it as a corporation: the owner is a shareholder, and Canada taxes the owner when the corporation distributes, as foreign dividend income, with no dividend tax credit (that credit is for Canadian corporations). Put those together for an LLC owner who becomes a Canadian resident and the timing and character split: year one, the US taxes the profit personally while Canada sees no income (nothing distributed) — the US tax finds no Canadian tax to credit against; year three, the LLC distributes and Canada taxes the full amount as investment income at high personal rates — and the US, which taxed those profits years ago, has no current tax for Canada to credit. The same dollars, taxed twice, in different years, as different kinds of income, by design. The treaty's fourth protocol added relief that helps in defined situations (Article IV(6) lets treaty benefits flow through fiscally transparent entities for US-source income), but it does not repair the core distribution mismatch for a Canadian-resident owner. The honest advice for most people moving with an LLC is structural: change what the entity is — to Canada, to the US, or to both — before the residency date.

Key takeaways

• The mismatch, precisely: US taxes profits as earned (flow-through); Canada taxes distributions when made (corporation). Foreign tax credits require the same income, same person, same period — the LLC breaks all three axes.
• It can also be a CFC problem in reverse and a filing generator: a Canadian-resident owner of a US LLC has T1134 foreign-affiliate reporting on the Canadian side, FAPI analysis if the LLC earns passive income, and the LLC's own US filings continue; the compliance stack alone rivals the double tax.
• Fixes before the move (best): dissolve or wind up the LLC and operate personally or through the right entity per side; or check-the-box the LLC to be taxed as a US corporation (aligning both countries on "corporation" — coherent, but now a genuine corporation with CFC/GILTI analysis for the US-citizen owner and cross-border corporate tax planning to do); or move the business into a Canadian corporation for go-forward activity, leaving the LLC as an empty shell to close.
• Fixes after the move (harder): the same moves, executed with a Canadian resident's exit and entry consequences attached — liquidating an LLC with appreciated assets after arrival can itself be a taxable event in both systems.
• S corporations are the different animal: a US citizen can keep S status while Canadian-resident (residency alone no longer kills the election for a citizen), and the treaty provides a competent-authority path (Article XXIX(5)) to align Canadian taxation with the S corporation's flow-through — imperfect but administrable. LLCs have no equivalent.
• Professional and consulting income has a clean landing: most one-person US LLC consultancies moving north do best as a plain Canadian corporation or Canadian sole proprietorship for new work, with the LLC retired. Sentiment about the old entity is not a tax attribute.

Why advisors still see this every month

Because nothing forces the question at the border. The LLC keeps working — invoices go out, the US return gets filed — and the problem only becomes visible when Canada taxes the first big distribution, or the T1134 non-filing surfaces, or a Canadian bank asks what this entity is. The cost of the do-nothing path compounds quietly: undistributed profits pile up US-taxed and Canada-pending, and every year of operation adds to the eventual reckoning.

Worked example

A marketing consultant moves from Nashville to Ottawa with her single-member LLC earning US$180,000 a year. Do-nothing path: the US taxes her US$180,000 annually as self-employment income; Canada, seeing a corporation, taxes her salary-free, dividend-free years at zero — then when she distributes US$300,000 of accumulated profits in year three, Canada taxes it as foreign investment income at roughly 48% Ontario rates with essentially no credit for the US tax paid in earlier years. Restructured path, executed the month before her residency date: the LLC distributes its retained cash while she is still US-only (no Canadian claim), she forms an Ontario corporation for go-forward client work (or simply operates unincorporated her first year while revenue clarifies), and the LLC files a final return and dissolves. Result: her business income is taxed once, in one country per period, with a structure each country recognizes — and her accountant's annual letter shrinks from a reconciliation memo to a checklist.

The IRS states that a single-member domestic LLC is "treated as an entity disregarded as separate from its owner," that "a domestic LLC with at least two members is classified as a partnership," and that an LLC changes its classification on "Form 8832, Entity Classification Election." — Internal Revenue Service, Limited Liability Company (LLC), https://www.irs.gov/businesses/small-businesses-self-employed/limited-liability-company-llc

The CRA states that "you may be able to claim the foreign tax credit if you paid foreign income or profit taxes" on income earned outside Canada, using "Form T2209, Federal Foreign Tax Credits." — Canada Revenue Agency, Federal foreign tax credit, https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-40500-federal-foreign-tax-credit.html

Practitioner note

LLCs are the single most common pre-move restructuring we do, and the urgency is real: every option is cheaper before the residency date than after. The framing that lands with clients — Canada will treat your flow-through as a corporation whether you like it or not, so choose your corporation deliberately or dissolve it — turns a technical mismatch into a decision they can actually make in the month they have.
