Mexico cryptocurrency tax guide

What this guide covers

No crypto-specific tax law exists in Mexico. This guide covers how the SAT instead applies Mexico's existing Income Tax Law (ISR) concepts to crypto, for the 2025 tax year, based on secondary sources. sat.gob.mx wasn't directly fetched in this research pass. This is educational information, not individualized tax advice.

Tax treatment of cryptocurrency

Cryptocurrencies aren't considered legal tender in Mexico. Their legal status rests primarily on the Fintech Law (Ley para Regular las Instituciones de Tecnología Financiera), which defines them as "Activos Virtuales." For tax purposes, the SAT reportedly folds crypto gains into the general ISR framework as a disposal of goods (enajenación de bienes) — the same category used for other intangible movable assets, not a separate, crypto-specific capital-gains regime.

Common taxable events

• Selling crypto for pesos — a disposal of goods under the ISR, with the gain added to the individual's other income for the year.
• Receiving crypto as payment for goods or services is reported as subject to VAT (IVA) on the business side of the transaction.
• Mining is reported as treated as self-consumption ('autoconsumo') requiring declaration — this guide did not independently confirm the exact mechanism against an official source.

Potentially non-taxable events

• Buying and holding crypto without disposing of it — not taxable.
• A wallet-to-wallet transfer between your own wallets — this guide didn't find official confirmation of an exemption here. Treat as unresolved pending direct confirmation.

Tax rates and thresholds

There's no separate crypto tax rate. Your gain is added to your total income for the year and taxed at Mexico's ordinary progressive ISR bracket rates, which this guide doesn't reproduce. Secondary sources genuinely conflict on the exact personal exemption figure for small gains, citing roughly MXN 124,000–128,383 per year — likely reflecting annual UMA (Unidad de Medida y Actualización) adjustments between sources of different vintages. This guide doesn't assert a single figure; confirm the current UMA-linked threshold directly with the SAT. A Prodecon preliminary study has reportedly floated a 20% ISR specifically on larger crypto sales exceeding a Federal Fiscal Code threshold. This guide treats that as an unconfirmed study, not enacted law.

Cost basis and calculation

Your taxable gain is disposal proceeds minus acquisition cost, consistent with the general ISR disposal-of-goods framework. This guide doesn't independently confirm Mexico's specific cost-basis identification convention for crypto — whether FIFO or another method is mandated.

Reporting and compliance

• Gains are reported as part of the individual's annual ISR return (Declaración Anual).
• Entities and frequent traders are reported as required to register in the Padrón de Actividades Vulnerables and report operations to the SAT under anti-money-laundering rules — a separate obligation from the income tax itself.
• This guide does not independently confirm the exact 2025-tax-year filing deadline — confirm directly with the SAT.

Residency and cross-border issues

Your Mexican tax residency governs whether your worldwide crypto gains fall within this regime. Using a foreign exchange doesn't, by itself, change this for a resident taxpayer. A reported 2026 OECD CARF reporting requirement for exchanges serving Mexican clients wasn't independently confirmed against an official source in this pass. This guide doesn't cover non-resident-specific rules in depth.

Example

This example is hypothetical, for illustration only. Diego buys 1 BTC for MXN 300,000 and sells it for MXN 500,000 — a MXN 200,000 gain. Mexico has no separate crypto capital-gains category, so the MXN 200,000 is added to Diego's other income for the year and taxed at his applicable progressive ISR bracket — not a flat rate, and not a special crypto rate.

Limitations and review information

Tax year covered: 2025. Last verified: October 29, 2026 (citation-integrity pass; source now individually verified and read directly). Known verification gap: sat.gob.mx and the Ley del ISR text itself were not directly fetched; the personal exemption figure is genuinely disputed across secondary sources, and the 20% withholding rule rests on a preliminary, non-binding Prodecon study rather than confirmed SAT policy. This is educational information only, not individualized tax advice — confirm current specifics directly with the SAT or a Mexican tax professional.
