How to buy bitcoin in Mexico

Is it legal to buy bitcoin in Mexico

Yes. There is no prohibition on individuals buying, holding, or selling bitcoin in Mexico. Bitcoin is recognised as a virtual asset under the Ley para Regular las Instituciones de Tecnologia Financiera, the Fintech Law, but both Banco de Mexico (Banxico) and the Comision Nacional Bancaria y de Valores (CNBV) have reaffirmed that it is not legal tender, as of March 2026. That means no one is obliged to accept bitcoin as payment, though private parties may agree to use it. The practical consequence of Circular 4/2019 is that you cannot buy bitcoin directly from a Mexican bank, because regulated financial institutions are barred from offering crypto services to the public. You buy instead from a dedicated crypto platform.

The compliant steps

Buying bitcoin compliantly in Mexico is a straightforward sequence. First, choose a platform that genuinely serves Mexican residents, such as the locally authorised Bitso or a major international exchange that supports peso funding. Second, complete the identity verification the platform requires under the anti money laundering rules, since virtual asset operations are a vulnerable activity under the Ley Antilavado. Third, fund your account with pesos, usually by a SPEI bank transfer from your own bank account or, on some platforms, a card. Fourth, place your order to buy bitcoin. Fifth, decide on custody: you can leave the bitcoin on the platform or move it to a wallet you control for self custody. Throughout, keep dated records of the peso amounts, because you will need them for tax when you eventually sell.

Where to buy

The platforms available to Mexican residents include the local exchange Bitso, which holds a CNBV authorisation as an electronic payment funds institution and supports peso deposits and withdrawals through SPEI, alongside major international exchanges including Binance, Coinbase, and Kraken, which serve Mexican users with peso funding. Compare fees, supported assets, peso funding options, and security before choosing, and confirm a platform's current status directly. See the best exchanges in Mexico page. This is information, not a recommendation of any one platform.

Tax when you sell

Buying and holding bitcoin is not a taxable event in Mexico. Tax arises on disposal. When you sell bitcoin for pesos, swap it for another crypto, or spend it, the Servicio de Administracion Tributaria (SAT) taxes the gain as income under the ISR, at progressive rates up to 35 percent, with the acquisition cost adjustable for inflation. Keeping the peso value of your purchase makes the later calculation manageable. See the Mexico crypto tax page. This is general information, not tax advice, so verify before filing.
