Capital gain tax Mexico is a topic every property buyer and investor should know about. While Mexico does apply a capital gains tax, the way it works is different than in the U.S. or Canada. Real estate sellers especially need to understand how it’s calculated, what deductions are available, and which exemptions apply.
At Baja Properties, we’ve worked with both locals and international clients who sell in Los Cabos. The good news: with proper planning and documentation, you can reduce your tax bill legally and keep more profit from your property sale.

Does Mexico Have a Capital Gains Tax and How Does it Work?
Yes, Mexico has a capital gains tax. It applies to residents and non-residents when selling assets for profit, including property, shares, and certain investments.
- For non-residents: You have two options when selling real estate. Pay a flat 25% tax on the gross sale price with no deductions, or pay 35% on the net gain after allowable deductions. Most choose the second option, but it depends on your records.
- For residents: The tax is calculated on net gain and follows Mexico’s progressive income tax rates (1.92% up to 35%). Residents may qualify for exemptions if it’s their primary home.
Deductible items include:
- The original purchase cost (with official CFDI tax receipts)
- Documented capital improvements (renovations with valid invoices)
- Agent commissions and professional fees
- Notary and legal costs
- Transfer taxes paid at purchase
All calculations must be done in pesos, even if the transaction is in U.S. dollars. The peso conversion is based on official exchange rates at the time of purchase and sale.

How Capital Gains Tax Applies to Real Estate in Mexico
The Basics for Buyers, Investors, and Sellers
Whenever you sell a residential property in Mexico for a profit, you’re subject to capital gains tax. The taxable amount is the net gain: sale price minus purchase price, improvements, and deductible expenses.
Notaries handle the tax calculation and collection at closing. Sellers should budget for this from the beginning. If you’re buying, it’s smart to keep every receipt and digital tax invoice so that when you sell, your gain is as small as possible on paper.
Exemptions and Allowances
- Primary residence exemption (Mexican residents only): If you’re a resident with a Mexican tax ID (RFC), you may exempt up to 700,000 UDIs (inflation-indexed units). As of 2025, that’s about 5–6 million pesos. This exemption can be used once every three years.
- Foreign sellers: There’s no direct exemption for non-residents. However, with proper deductions you can lower the taxable gain.
For a property to qualify as your main home, you must prove residency (utility bills, voter ID, or tax returns).
Common Mistakes and Compliance
- Not saving receipts: Improvements without official invoices cannot be deducted.
- Missing CFDI documents: Without them, your purchase price may not count fully.
- Assuming foreign exemptions apply: U.S. or Canadian tax breaks don’t carry over to Mexico.
Every sale should include a full closing package and a digital tax receipt. A trusted notary ensures the tax is calculated correctly and reported to Mexico’s SAT (tax authority).

Capital Gains Tax in Cabo San Lucas & Baja California Sur
Cabo follows the same capital gains rules as the rest of Mexico, but sellers here should also plan for:
- Property transfer tax: Usually 2–5% of the transaction, depending on the municipality.
- Annual property tax: Los Cabos property taxes are low compared to the U.S., but they must be current before a title can transfer. See our full guide on Los Cabos cost of living.
With Cabo’s active expat and vacation home market, many sellers are foreign owners. Budgeting for capital gains plus transfer costs ensures you’re not surprised at closing.
Common search terms like Cabo capital gains tax, Baja California Sur real estate tax, and Los Cabos seller rules all point to the same reality: rules are national, but local costs add up.
Planning Ahead: Tips for Protecting Your Profits
- Document everything: Keep invoices for every improvement - kitchen remodels, new roofs, landscaping. No invoice, no deduction.
- Stay current on property taxes: Being behind can delay a sale.
- Use experts: A local notary and tax advisor will help you apply the right deductions and exemptions.
- Plan timing: If you qualify as a resident, timing your sale can maximize your exemption.
- Know your options: Non-residents can sometimes save more by choosing the 25% gross option if they don’t have strong documentation.
Selling in Mexico isn’t complicated, but it requires paperwork discipline. At Baja Properties, we encourage clients to think about capital gains before they buy - not just when it’s time to sell.
