🌴 COUNTRY A Florida VS 🍁 COUNTRY B Canada

Yes — the United States taxes its citizens on worldwide income regardless of where they live. An American who moves to Canada must still file a US federal tax return every year. The US-Canada tax treaty and foreign tax credit system are designed to prevent double taxation: taxes paid to Canada can generally be credited against the US tax liability on the same income. However, the filing obligation remains, and Americans with Canadian bank accounts, RRSPs, or TFSAs must also comply with FBAR and FATCA reporting requirements.

Canada considers you a tax resident if you spend 183 or more days in the country in a calendar year — or if you establish significant residential ties such as a home, spouse, or dependents in Canada. Florida snowbirds who spend winters in Florida and summers in Canada need to carefully track their days. Exceeding 183 days in Canada could trigger Canadian tax residency, meaning Canada would tax your worldwide income at its progressive federal+provincial rates. The US-Canada tax treaty provides tie-breaker rules, but the situation can become complex quickly.

Canada has a two-tier income tax system. The federal government taxes income at progressive rates from 15% on the first $57,375 CAD up to 33% above $246,752 CAD. Each province then levies its own additional income tax — Ontario's rates run from 5.05% to 13.16%. These two sets of rates are stacked, meaning a resident of Ontario pays both federal and provincial rates on every dollar of income. At $100,000 USD equivalent, the combined Ontario+federal burden reaches approximately $24,385 USD, versus $0 in Florida state tax.

Yes — Americans living and working in Canada may qualify for the Foreign Earned Income Exclusion (FEIE) under IRS Form 2555, provided they pass either the Bona Fide Residence test (establishing genuine Canadian residency) or the Physical Presence test (330 days outside the US in a 12-month period). The FEIE exclusion amount for 2025 is $126,500, indexed for inflation. However, many Americans in Canada find it more advantageous to claim the Foreign Tax Credit instead of FEIE, since Canadian taxes are typically higher than US federal rates, meaning the credit fully offsets the US liability.

Yes — the US-Canada Tax Convention (originally signed in 1980, with multiple protocols) is one of the most comprehensive bilateral tax treaties in the world. It covers the treatment of employment income, business profits, dividends, interest, royalties, and capital gains. For Americans living in Canada, the treaty's most important provisions determine which country has primary taxing rights on various income types and provide relief from double taxation through the foreign tax credit mechanism. The treaty also contains provisions for RRSP (Registered Retirement Savings Plan) treatment, which the IRS generally allows to grow tax-deferred.

Beyond income taxes, the cost comparison involves several factors. Canada has universal healthcare, eliminating health insurance premiums but funded through higher taxes. Housing in Toronto and Vancouver is extremely expensive — comparable to Miami or Tampa in cost. Canadian goods and services attract 13% HST in Ontario versus Florida's 6% sales tax. Gasoline, groceries, and consumer goods are generally more expensive in Canada. Florida's lower overall tax burden (zero state income tax, lower property tax rates in many counties) combined with lower healthcare costs often makes Florida the more affordable option for higher earners.
