Understanding Property Taxes and Capital Gains in Los Cabos
For American buyers accustomed to property tax rates of 1-3% of market value annually, the Mexican property tax system comes as a pleasant surprise. Property taxes in Los Cabos — known as predial — are remarkably low, often amounting to just a fraction of what the same property would be taxed in California, Texas, or Florida. However, the broader tax picture for foreign property owners in Mexico includes several components that buyers should understand before purchasing.
This guide covers everything American buyers need to know about property taxes, capital gains taxes, rental income taxes, and tax planning strategies for Los Cabos real estate.
Predial: Annual Property Tax
The predial is Mexico's equivalent of U.S. property tax, assessed annually by the municipal government (Ayuntamiento de Los Cabos). The key differences from U.S. property tax:
- Assessment basis: Predial is calculated on the catastral (cadastral) value, which is typically 20-40% of actual market value
- Rates: The effective rate varies but generally results in annual taxes of 0.1-0.3% of market value
- Early payment discount: Most municipalities offer a 15-25% discount for paying the full year's predial in January
Typical Predial Amounts in Los Cabos
- $500,000 condo: $500-$1,200 USD annually
- $1M home: $800-$2,000 USD annually
- $3M estate: $2,000-$5,000 USD annually
- $10M+ trophy property: $5,000-$15,000 USD annually
Compare this to a $3M home in California (approximately $30,000-$36,000 annually) or Texas (approximately $60,000-$75,000 annually), and the savings are dramatic.
Capital Gains Tax (ISR) When You Sell
This is where the Mexican tax system gets more complex, and where proper planning can save American sellers tens or even hundreds of thousands of dollars.
How Mexican Capital Gains Tax Works
When you sell property in Mexico, the notario público calculates and withholds the income tax (Impuesto Sobre la Renta — ISR) at closing. There are two methods for calculating this tax:
- Flat rate method: The notario withholds a flat percentage (typically 25-35%) of the gross sale price. This is the simpler method but almost always results in a higher tax burden.
- Net gains method: The notario calculates the actual gain by subtracting the original purchase price (adjusted for inflation), closing costs, documented improvements, and applicable deductions. The tax is then applied to the net gain at progressive rates ranging from 1.92% to 35%.
Always request the net gains method. It requires more documentation but virtually always results in a lower tax liability.
Key Deductions to Reduce Capital Gains
- Inflation adjustment: Your original purchase price is adjusted upward using Mexico's official inflation index (INPC), reducing the taxable gain
- Documented improvements: Renovations, additions, and improvements supported by facturas (official tax invoices) are deductible. This is critical — save every factura from every contractor, architect, and supplier.
- Closing costs: Both the original purchase closing costs and the sale closing costs are deductible
- Notario fees and commissions: Real estate commissions paid at both purchase and sale are deductible
Primary Residence Exemption
If the property is your primary residence and you can demonstrate residency (temporary or permanent resident status in Mexico), you may qualify for a capital gains exemption on sales up to approximately $700,000 USD (the peso-denominated limit is adjusted annually for inflation). This exemption can only be used once every three years.
Rental Income Tax
If you rent your Los Cabos property, the income is taxable in Mexico. There are two common approaches:
Individual Tax Returns
Rental income for individuals is taxed at progressive rates from 1.92% to 35%. However, you can deduct operating expenses including:
- Property management fees
- Maintenance and repairs
- Utilities (if owner-paid)
- HOA fees
- Insurance
- Depreciation of the structure (not land)
- Fideicomiso fees
After deductions, the effective tax rate on net rental income is typically 15-25%.
Mexican Corporation
Many investors with significant rental operations establish a Mexican corporation (SA de CV or S de RL de CV). The corporate tax rate is a flat 30%, but with broader deduction options and the ability to carry forward losses, the effective rate on net income is often lower than the individual progressive rate. Corporations also provide liability protection and can be more tax-efficient for properties with high gross revenue.
U.S. Tax Obligations
American citizens and permanent residents must report worldwide income to the IRS, including Mexican rental income and capital gains from property sales. However, several mechanisms help avoid double taxation:
- Foreign Tax Credit: Taxes paid to Mexico can generally be credited against U.S. tax liability on the same income
- FBAR reporting: If you have Mexican bank accounts (including escrow accounts) exceeding $10,000, you must file an FBAR (FinCEN Form 114)
- Form 8938: Foreign financial assets exceeding certain thresholds must be reported on Form 8938 with your tax return
- Depreciation: You can depreciate the structure portion of your Mexican property on your U.S. return
Work with a cross-border tax professional who understands both Mexican and U.S. tax law. The cost of proper tax planning ($2,000-$5,000 annually) is typically a fraction of the savings achieved.
Estate and Inheritance Considerations
Mexico does not have a federal estate tax or inheritance tax. However, proper estate planning is essential:
- Mexican will: Having a Mexican will (testamento) specifically covering your Mexican property ensures smooth transfer to heirs and avoids the need for U.S. probate proceedings in Mexico
- Substitute beneficiaries: Your fideicomiso should name substitute beneficiaries to facilitate transfer upon death
- U.S. estate tax: Your Mexican property's fair market value is included in your U.S. taxable estate. Proper planning with your U.S. estate attorney is essential for high-value properties
Tax Planning Best Practices
- Keep every factura (official invoice) for improvements, furnishings, and services — these are your capital gains deductions
- Register improvements with the notario and update the catastral value periodically
- Pay predial early each January to capture the discount
- Consider residency if you spend significant time in Mexico — the primary residence exemption is valuable
- Use a cross-border CPA who files returns in both countries
- Structure correctly from the start — fideicomiso vs. corporation has long-term tax implications
The low property tax burden in Los Cabos is one of the market's most attractive features for American buyers. Combined with proper planning around capital gains, rental income, and estate matters, the total tax cost of owning property in Mexico is typically far lower than comparable U.S. coastal markets.
