Bitcoin in Mexico: rules, tax and how it's priced
In Mexico bitcoin is quoted as the price of one whole BTC in Mexican pesos (MXN), and platforms let you buy fractions, so small purchases are often shown in sats (1 BTC = 100 million satoshis). The figures on this page are the international BTC/USD price converted into pesos at today's exchange rate, before exchange fees, spreads and any local premium, so a Mexican platform's quote can differ slightly.
Is bitcoin legal in Mexico?
Owning and trading bitcoin is legal in Mexico, but it is not legal tender. The 2018 Fintech Law (Ley para Regular las Instituciones de Tecnología Financiera) defines crypto as “virtual assets” and excludes them from legal tender. The Banco de México keeps virtual assets at a distance from the financial system: under its Circular 4/2019, banks and fintech institutions may use them only in internal operations, not offer them to the public. In a joint statement in June 2021, Banxico, the Finance Ministry (SHCP) and the banking regulator (CNBV) repeated that bitcoin is not legal tender, that financial institutions are not authorised to offer it to customers, and that blockchain-based peso or dollar stablecoin services had not been authorised.
How bitcoin is taxed in Mexico
Mexico has no special crypto tax regime. For individuals, a profit on selling bitcoin is generally treated as income from the disposal of assets under the Income Tax Law (ISR): the gain is the sale price minus the inflation-adjusted cost, and it is declared in your annual return and taxed at the progressive individual rates, which go up to 35%. Swapping one crypto for another or paying for goods with bitcoin can also count as a disposal, while moving coins between your own wallets does not. Income from mining, staking or rewards is generally taxable when received. Mexico has committed to the OECD's Crypto-Asset Reporting Framework (CARF), so the SAT will increasingly receive data from exchanges.
Buying bitcoin in Mexico
Because banks cannot sell bitcoin to their customers, Mexicans buy through crypto platforms, funding accounts with a peso bank transfer, or peer-to-peer. These platforms are not licensed by Banxico as crypto banks; instead, exchanging virtual assets is classified as a “vulnerable activity” under the federal anti-money-laundering law (LFPIORPI), so platforms must register with the SAT, verify customers and report to the authorities. Expect to provide official ID and proof of address before you can buy. Keep your own records of purchase prices and dates, since you will need them to calculate any gain for your annual tax return.
Anti-money-laundering reporting thresholds
Under the LFPIORPI, platforms that habitually exchange virtual assets must identify every customer, whatever the amount. They must also file a notice (aviso) with the authorities, which is passed to the Financial Intelligence Unit (UIF), for operations at or above a threshold expressed in UMA, Mexico's indexed reference unit. A reform published in the Diario Oficial on 16 July 2025 cut that threshold from 645 to 210 UMA per operation, about MX$24,600 at the 2026 UMA value. The notice is a routine compliance report, not a tax; it does not mean you have done anything wrong, but it does mean larger purchases are visible to the authorities.
