Mexico Real Estate Taxes for Americans: What You Need to Know in 2026

Taxes are the topic that scares most foreign buyers away from Mexico — unnecessarily. The Mexican tax system for real estate is actually simpler than many buyers expect, and with proper structuring, the tax burden is often lower than in the US.

Here’s the complete breakdown.

1. Purchase Tax (ISAI)

When you buy property in Mexico, you pay the ISAI (Impuesto Sobre Adquisición de Inmuebles — Property Acquisition Tax).

Rate in Yucatan: 2% of the fiscal value (valor catastral) — not the purchase price.

Important: The fiscal value in Yucatan is often lower than market value, which reduces the tax. Your notary calculates this and collects it at closing.

Who pays: The buyer.

Typical cost: For a $200,000 USD property, expect $3,000–$6,000 USD in ISAI (depending on the catastral value, which varies).

2. Capital Gains Tax (ISR on Sale)

When you sell property in Mexico, you may owe ISR (Impuesto Sobre la Renta — Income Tax) on the profit.

Rate: 25% of the total sale price, OR 35% of the net gain (profit) — whichever is lower, calculated by the notary.

Key deductions that reduce your taxable gain:

Purchase price (adjusted for inflation)
Notary and closing costs paid when you purchased
Major improvements (with receipts/invoices — CFDI)
Real estate agent commission paid upon sale
ISAI paid at purchase

The principal residence exemption: If the property is your primary residence AND you’ve lived there for at least 2 years, you may exclude up to MXN $3,497,780 from capital gains (approximately $175,000 USD). This exemption can only be used once every 5 years.

Practical example:

Purchase price: $200,000 USD (MXN $4,000,000)
Sale price: $320,000 USD (MXN $6,400,000)
Net gain: $120,000 USD (MXN $2,400,000)
ISR at 35% of net gain: ~$42,000 USD — unless exemptions apply

3. Rental Income Tax (ISR on Rents)

If you rent your Mexican property — whether through Airbnb, long-term leases, or direct arrangements — you owe ISR on that income.

Flat rate option: 35% on gross rental income (minus a small deduction for the bank trust fee if applicable)

Itemized deduction option: Pay tax on net rental income after deducting:

Property taxes (predial)
Maintenance fees (HOA)
Insurance
Maintenance and repairs (with receipts)
Property management fees
Depreciation (3% of construction value per year)
Bank trust fees
Interest on any property loan

Most investors choose the itemized option, which significantly reduces the effective tax rate.

VAT (IVA): Residential rental income is exempt from VAT. Vacation rentals (Airbnb) technically are commercial activity — rules are evolving, and some large property management companies are now collecting IVA.

4. Annual Property Tax (Predial)

The Mexican equivalent of property taxes is the predial, paid annually to the municipal government.

In Merida: Very low — typically MXN $1,000–$4,000 per year for most residential properties ($50–$200 USD). Pay in January for a 10–20% discount.

5. US Tax Obligations for Americans Owning Mexican Property

Americans must report worldwide income to the IRS. Your Mexican property creates several US tax obligations:

FBAR (FinCEN 114): If you have foreign financial accounts (including the bank trust account for your property) exceeding $10,000 at any point during the year, you must file FBAR. Important: A bank trust (fideicomiso) IS considered a foreign financial account for FBAR purposes.

Form 8938 (FATCA): Required if your foreign financial assets exceed $50,000 (single) or $100,000 (married).

Rental income: Must be reported on your US return (Schedule E). You can claim a Foreign Tax Credit for ISR paid in Mexico, which reduces your US tax liability. Double taxation is generally avoided through this credit.

Capital gains on sale: Report the gain on your US return. Foreign tax paid to Mexico on the gain can typically be credited against your US capital gains tax.

6. Canadian Tax Obligations

T1135 (Foreign Income Verification): Required if foreign property cost more than CAD $100,000.

Rental income: Reported on Canadian return. Foreign tax credits apply for ISR paid in Mexico.

Capital gains: Mexico’s ISR on sale is credited against your Canadian capital gains tax under the Canada-Mexico tax treaty.

Common Tax Mistakes to Avoid

Not keeping receipts for improvements. Every peso you spend on qualifying improvements (with proper CFDI receipts) reduces your future capital gains tax. Keep everything.
Not registering your RFC. To legally rent property or sell with proper documentation, you need a Mexican RFC (tax ID). Get this early.
Not using the principal residence exemption. If you qualify, using this exemption on a high-gain sale can save tens of thousands of dollars.
Forgetting the FBAR. The penalties for non-filing are severe ($10,000+ per violation). File it.
Assuming you owe no US tax because you paid Mexico. You must report AND file the foreign tax credit. It doesn’t happen automatically.

Recommended Tax Strategy

For Americans buying in Merida:

Register an RFC in Mexico as soon as you start generating rental income
Work with a bilingual accountant who handles both US and Mexican returns
Keep all receipts for improvements (ask for official CFDI invoices, not just receipts)
If selling, get a tax projection from the notary before signing the listing agreement
Consider whether the principal residence exemption applies to your situation
