Mexico Crypto Tax Guide 2026

Mexico does not have specific crypto tax legislation, but the Servicio de Administración Tributaria (SAT) treats cryptocurrency gains as taxable under the general income tax framework (Ley del Impuesto sobre la Renta, LISR). Crypto disposals may be taxed as capital gains (enajenación de bienes) or as business income depending on the nature of the activity. Mexico's Fintech Law (2018) recognized virtual assets and gave the Banco de México regulatory authority over crypto used by financial institutions, but individual taxation falls under general ISR rules. The SAT has been increasing its focus on crypto compliance and has begun requesting transaction data from exchanges.

Capital gains from cryptocurrency disposals are subject to ISR (Impuesto sobre la Renta) at progressive rates. For individuals, the marginal rates range from 1.92% to 35%, depending on your total annual income. The gain is calculated as the disposal proceeds minus the verified acquisition cost (costo comprobado de adquisición). Inflation adjustment (actualización) may be applied to the cost basis to account for peso devaluation. Crypto-to-crypto trades are generally considered taxable events. If crypto trading constitutes a business activity (actividad empresarial), different rules and rates may apply, including potential VAT implications.

Mexican taxpayers who earn income from crypto disposals may be required to make monthly provisional tax payments (pagos provisionales) to the SAT. These are advance payments toward your annual tax liability, calculated based on the gains realized in each month. The provisional payment rate for capital gains from asset disposals is typically 20% of the gross proceeds (not the gain), which is then reconciled in your annual return. This can create cash flow challenges since the provisional rate may exceed your actual tax rate on the net gain.

Staking rewards and mining income are taxable as ordinary income (ingresos acumulables) at your marginal ISR rate when received. The fair market value in MXN at the time of receipt determines the taxable amount. If mining is conducted as a business, it may be classified under the business activity regime with obligations including monthly ISR and VAT declarations. Airdrops and interest from DeFi lending are similarly treated as taxable income upon receipt. The income value at receipt establishes the cost basis for future disposals.

Crypto gains must be reported on your annual income tax return (Declaración Anual de ISR), filed by April 30 of the following year. Capital gains from crypto are reported in the enajenación de bienes section. You need to maintain detailed records including purchase receipts, sale confirmations, exchange statements, and wallet transaction histories. The SAT requires invoices (CFDI) for deductible expenses. Mexico participates in international tax information exchange agreements, and the SAT is developing capabilities to track crypto transactions through exchange data sharing.

Taxxy calculates crypto gains using FIFO and converts all values to MXN using historical exchange rates. The platform generates a comprehensive gains report compatible with SAT annual filing requirements, separating capital gains from income events. Taxxy calculates monthly provisional payment obligations and tracks the annual ISR liability at your marginal rate. The platform also flags high-frequency trading patterns that may indicate business activity classification.
