Mexico vs Arizona for Canadian Snowbirds — Cost, Lifestyle, and Tax Comparison

FIRPTA — the Foreign Investment in Real Property Tax Act — is a US federal law that requires the buyer to withhold 15% of the gross sale price when a foreign person (including a Canadian) sells US real estate. This withholding is not a tax itself but a prepayment against any potential US capital gains tax. The withheld amount is submitted to the IRS at closing, and the Canadian seller must file a US non-resident tax return (Form 1040-NR) to either confirm the tax was correct or claim a refund of the excess. The refund process typically takes 6–12 months. For a Canadian selling a $500,000 USD Arizona property, that's $75,000 USD held back at closing — even if the actual capital gains tax owed is far less. Most Canadians buying in Arizona are unaware of this until they try to sell.

Generally, no annual US tax return is required if you own Arizona real estate but have no US-sourced income. Passive property ownership without rental income typically does not trigger a US filing obligation. However, if you rent your Arizona property — even short-term Airbnb rentals for a few weeks while you're away — you have US rental income that must be reported to the IRS on Form 1040-NR. You'll also need to file when you sell (for FIRPTA purposes). Additionally, you must file the T1135 form with CRA annually once your total foreign property cost exceeds $100,000 CAD — this applies to Arizona property the same as Mexico property.

This is the single biggest financial risk of choosing Arizona over Mexico, and it's routinely underestimated. As a Canadian in Arizona, you are in the US healthcare system — the most expensive in the world. Your provincial health coverage provides minimal-to-no coverage in the US. Travel insurance covers emergencies for the first 90–180 days of a trip, but if you're spending 5–6 months per year, a longer-term US expat health plan is essential. These plans run $4,000–$12,000 CAD/year for a couple depending on age and coverage level. One uncovered US emergency hospitalization can cost $30,000–$100,000+ USD. In Mexico, a full private expat health insurance policy runs $2,000–$4,000 CAD/year for a couple and covers hospital care, surgery, and specialist visits at Mexican private hospitals — which are modern and excellent in major resort cities.

Arizona has historically been the default for Western Canadian snowbirds because of the short flight (2.5 hours Calgary to Phoenix), USD familiarity, English language, and the established retirement communities in Sun City and Scottsdale. But the cost gap has widened significantly in the last five years: Arizona real estate has appreciated substantially, while Mexico's resort markets remain 50–60% cheaper for comparable properties. Albertans and BC residents who priced themselves out of Scottsdale in the 2020–2024 run-up are actively looking at Puerto Vallarta, Mazatlán, and Cabo — all with direct flights from Calgary, Edmonton, and Vancouver at comparable or shorter times than Phoenix. Mexico's combination of lower entry price, dramatically lower property tax, lower healthcare costs, and no FIRPTA exposure is compelling for cost-conscious buyers.

A fideicomiso is a bank trust where a licensed Mexican bank (BBVA, Banorte, HSBC Mexico, Scotiabank Mexico) holds legal title to coastal property on your behalf, with you as the named beneficiary with full rights to use, rent, sell, and pass the property to heirs. It's required for all foreign buyers purchasing within 50km of any Mexican coastline. The fideicomiso is not a risk — it is a well-established legal structure used by hundreds of thousands of foreign property owners for over 40 years. The main risks people associate with it are misunderstood: the bank does not have discretion over your property, cannot sell it, and cannot prevent you from selling it. The primary practical consideration is the annual trust fee ($550–$1,000 USD) and the need to name substitute beneficiaries for estate planning. Compare this to Arizona: no trust required, direct title — but FIRPTA and US tax complexity instead.

Yes, in both countries, but with different administrative profiles. In Arizona, renting your property creates US rental income that must be reported to the IRS on Form 1040-NR. You can deduct expenses (mortgage interest, depreciation, management fees) and may pay little or no actual tax, but the filing requirement exists regardless. In Mexico, non-resident rental income is subject to Mexican income tax at 25% of gross revenue (or 35% on net income if you elect that option) — your property manager typically withholds and remits this. Both countries also require CRA reporting in Canada. Mexico's rental market in PV and Cabo tends to generate higher gross yields (6–9%) than Arizona's typical condo market (4–6%), partly because the purchase price is so much lower in Mexico.

OAS and CPP are not affected by spending time in either country, provided you remain a Canadian tax resident (which most snowbirds do). CPP is payable worldwide unconditionally. OAS requires 20 years of Canadian residency after age 18 and is payable abroad. As a Canadian tax resident spending time in Arizona or Mexico, you continue filing Canadian taxes and receive your OAS and CPP normally. The issue arises if you actually emigrate — non-residents face 25% withholding on OAS/CPP, reducible under Canada's tax treaties with both the US and Mexico. The GIS (Guaranteed Income Supplement) is never payable outside Canada regardless of duration. Snowbirds who return to Canada before the 183-day threshold are almost universally Canadian tax residents and unaffected.

The 183-day threshold matters differently in each country. For Canada, spending more than 183 days outside Canada in a calendar year doesn't automatically make you a non-resident — CRA uses a residential ties test. But for the US specifically, there is a separate Substantial Presence Test that can make you a US tax resident if you exceed 183 days across a 3-year weighted formula. Most snowbirds staying 4–6 months annually in Arizona will not trigger this (the formula weights current-year days at 1x, prior year at 1/3, and two years back at 1/6), but it's worth annual tracking. Mexico has no equivalent trap — staying up to 180 days on a tourist permit creates zero Mexican tax residency exposure.
