🇺🇸 United States — 🇨🇦 Canada

Tax Treaty / Double Tax Avoidance Agreement detail

The US-Canada Income Tax Convention was originally signed in 1980 and has been amended by five protocols, the most significant being the Fifth Protocol of 2007 which entered into force in December 2008. It is among the most heavily utilised tax treaties globally given the deep economic integration between the two neighbours. Dividend withholding is reduced to 5% where the recipient company owns at least 10% of the voting shares of the paying company, and 15% in all other cases. Under the Fifth Protocol, certain cross-border interest payments between arm's-length parties are fully exempt from withholding, bringing the treaty in line with modern standards. Royalties for cultural royalties (payments for copyright of literary, artistic, or musical works) remain taxable at 10%, while other qualifying royalties are exempt. The treaty includes a robust Limitation on Benefits article added in the 1995 Fourth Protocol to guard against treaty shopping. Qualified persons include Canadian and US residents meeting ownership and base-erosion tests, publicly traded entities, and pension plans. A saving clause preserves each country's right to tax its own residents and citizens under domestic law. US citizens resident in Canada are a notable group affected: they remain subject to US worldwide taxation regardless of the treaty, except for specific carve-outs such as the Article XXV(3) credit mechanism that partially relieves double taxation on Canadian-source income. The treaty also governs taxation of capital gains, real property income, and business profits through permanent establishment rules. Cross-border workers near the border have special provisions. The separate US-Canada Totalization Agreement prevents double social security contributions and co-ordinates benefit entitlements.
