Property Sale Tax Calculator Mexico

How This Is Calculated

Sale price in USD is converted to MXN at the selected exchange rate.

The original purchase price is inflation-adjusted using Mexico's official INPC index (approximate 3%/yr for simplicity). Commissions, notary and closing costs are deducted from the sale price.

For tax residents of Mexico: ISR is calculated at 35% on net capital gain (sale price minus adjusted cost basis minus deductible expenses).

For non-residents: we calculate both 25% on gross sale price and 35% on net gain, then apply whichever is lower per Art. 126 LISR.

Results are estimates only. A Mexican notary and tax advisor should review your specific transaction. Individual results may vary significantly based on avalúo, deductible improvements, and tax residency status.
