Foreign owners often overpay — or get surprised by — capital gains tax (ISR) when they sell in Mexico. Get a fast estimate of your net proceeds and see where the money goes.
Adjust the cost assumptions
This is an estimate only. In Mexico the Notario Público calculates and withholds the actual ISR at closing — in pesos, not dollars — and has the final say on your rate, deductions, and any exemptions. Confirm every figure with your notario and a cross-border tax professional before relying on it. Your U.S. tax side is separate and not included here.

Estimates are informational and not legal, tax, or financial advice. Mexican capital gains tax is assessed in pesos and finalized by the Notario Público, whose determination governs. Sources: SAT / Mexican Income Tax Law (LISR); typical Sonora / Puerto Peñasco transaction costs, 2026.
