Mexico Real Estate: Legal & Tax Information
The tax and cost picture in Mexico differs enough from Canada's that it's worth understanding before you budget a purchase or plan a sale — not after. Here's what actually applies to a foreign buyer or seller.
Closing costs: budget 5–8% of the purchase price
Total closing costs for a foreign buyer are commonly cited in the 4–8% range, trending toward the higher end for lower-priced properties or any purchase requiring a new fideicomiso (whose setup cost weighs proportionally more on a smaller transaction). The main components: the acquisition/transfer tax (ISAI), set by the state and municipality — commonly around 2–4.5% of the higher of the appraised or sale value; notario fees, typically 1–2% of value plus Mexico's 16% IVA (value-added tax) on the professional-fee portion; Public Registry registration, roughly 0.5–1%; and, for restricted-zone purchases, the fideicomiso setup cost described in our Foreign Ownership guide. Get a specific quote from your notario once you have an accepted offer — this range is a planning tool, not a substitute for their final number.
The seller typically pays the real estate commission (commonly 5–8% plus IVA) and any capital gains tax owed.
Capital gains tax (ISR) — a real difference from home
Mexico's principal-residence capital gains exemption is reserved for Mexican tax residents with a Mexican tax ID, and doesn't apply to non-resident foreign owners — which is the situation for the large majority of Canadian buyers. On sale, the notario, as withholding agent, calculates tax two ways and applies whichever is lower: 25% of the gross sale price with no deductions, or roughly 35% of the net gain, but only if you can substantiate your cost basis and improvements with proper SAT-registered invoices (facturas). Many foreign owners can't produce clean invoices for a purchase made years ago or for informally paid renovation work, which in practice often pushes the calculation toward the 25%-of-gross method by default.
Either way, this is a materially higher effective rate than most Canadian sellers are used to at home, and it's calculated and withheld at closing — not something you settle later at tax time. Keep every purchase and improvement invoice from day one if you plan to eventually sell; it's the only way to access the lower net-gain calculation.
Annual property tax (predial) — genuinely low
Predial, Mexico's annual municipal property tax, is calculated on the government's cadastral (assessed) value — typically only 30–60% of actual market value — at rates commonly in the 0.05–1.2% range, with most residential property toward the lower end. The combination of a below-market assessed value and a low rate means the real annual bill is consistently a small fraction of what an equivalent property would cost in property tax in BC or Alberta. Most municipalities offer an early-payment discount (often up to 20%) for paying in January or February, and the tax is due annually.
Renting out your property
If you plan to rent your Mexican property — through Airbnb or otherwise — the tax treatment differs meaningfully depending on whether you hold a Mexican tax ID (RFC). A foreign individual beneficiary without an RFC can face steep withholding on gross rental payouts through some platforms; this is a real, practical reason some investment-focused buyers choose to register for an RFC or hold rental property through a Mexican corporation instead of an individual fideicomiso. If rental income is part of your plan from the outset, raise this with your accountant before you buy, not after your first booking.
Mexico Real Estate: Legal & Tax Information — FAQs
Is there a way to reduce the 25%/35% capital gains withholding?
The net-gain method (roughly 35% of the actual gain, versus 25% of the full sale price) is usually the better outcome if your gain is modest relative to the price — but it requires proper SAT-registered invoices for your original purchase and any capital improvements. Keep those documents from the day you buy; without them, the notario will typically default to the 25%-of-gross calculation.
How does Mexican property tax actually compare to what I'd pay in BC or Alberta?
Materially lower in almost every case, because Mexico taxes a below-market assessed value at a low rate, versus a market-value assessment in Canada. It's one of the most consistent, genuine cost advantages of owning in Mexico versus at home.
Do I need a Mexican accountant, or just a notario?
For a straightforward purchase and eventual sale, the notario handles the required tax calculation and withholding. If you plan to rent the property, hold it through a corporation, or want to actively manage your Mexican tax position, a Mexican accountant becomes genuinely worth having alongside your notario and attorney.
