Crypto Taxation in Mexico: A Complete Guide

In 2025, Mexico embraces trading digital assets like Bitcoin, marking a notable boom in adoption. As more dive into this digital trend, knowing tax rules becomes essential to protect earnings. Mishandling taxes can shrink profits, and the Servicio de Administración Tributaria (SAT) ensures everyone follows the law. This guide breaks down Mexico’s crypto tax system, rates, and filing steps, aiding individuals in staying lawful and dodging penalties.

Tax Authorities & Regulations 

The Servicio de Administración Tributaria (SAT) handles cryptocurrency oversight in Mexico.

Lacking a specific crypto law, SAT uses the Income Tax Law (ISR), viewing crypto as “intangible assets”, not money or real estate. This policy kicked off in 2018, and by 2025, SAT has sharpened its watch, tapping exchange records and blockchain tech to monitor trades. The Fintech Law (2018) oversees platforms, yet all crypto actions—buying, selling, or earning—face taxation, leaving no gaps for avoidance.

Types of Crypto Taxes in Mexico

• Income Tax (ISR): Applies to profits from selling crypto or earnings from mining, staking, or payments.
• Value-Added Tax (VAT): Charged at 16% on exchange fees or services, not direct crypto trades.
• Other Taxes: No wealth or inheritance taxes apply to crypto as of 2025, though future rules may emerge.

Tax Rates & Brackets

• ISR rates for individuals range from 1.92% to 35%, based on total income, including crypto gains.
• Businesses pay a flat 30% ISR on crypto profits.
• An annual ISR exemption of 90,000 MXN ($4,500 USD) applies to small gains for individuals.
• VAT on fees is fixed at 16%, with no exemptions for crypto-related services.

Crypto Transactions & Tax Treatment

• Buying and Selling Crypto: Buying is tax-free; selling triggers ISR on profits.
• Crypto Mining and Staking: Earnings are taxed as income (1.92%–35%) when received.
• Crypto Received as Payment: Taxed as income at the recipient’s ISR rate.
• Crypto-to-Crypto Trades: Treated as a sale, taxable under ISR on gains.
• DeFi Activities, Lending, Yield Farming: Taxed as income, pending clear SAT guidance.
• NFT Transactions: Follows crypto rules, with ISR on profits from sales.

Crypto Tax Reporting & Compliance 

Individuals must report crypto gains on their annual tax return, filed via SAT’s online portal by April 30 for the prior year (January 1–December 31). They need records of all transactions—dates, amounts, and peso values—using methods like First-In-First-Out (FIFO). Records must be kept for five years. Late or missing reports can lead to fines or audits, with SAT increasingly vigilant in 2025.

Tax Deductions & Exemptions 

Individuals can ease their tax load with a 90,000 MXN ($4,500 USD) annual ISR exemption for small crypto gains. Losses from sales can offset gains, reducing ISR liability. Businesses may deduct costs like mining equipment if properly documented. No crypto-specific exemptions exist, but careful reporting maximizes benefits. A tax expert can ensure accuracy.

Enforcement & Penalties for Non-Compliance 

SAT enforces crypto taxes strictly in 2025, using KYC data from exchanges, blockchain analysis, and AI to detect unreported gains. In 2021, platforms like Bitso share user info, and by 2027, global data agreements will expand SAT’s reach. Non-compliance risks fines starting at 1,400 MXN (~$70 USD) per violation, escalating to 20% of unreported amounts, or jail time up to five years for evasion. The Voluntary Disclosure Program offers leniency if reported before SAT acts, critical as crypto use surges.

Future of Crypto Taxation in Mexico

Crypto rules may tighten as SAT eyes stricter platform oversight with the Fintech Law. A 2027 global Crypto-Asset Reporting Framework will boost cross-border tracking. The Bank of Mexico’s planned digital peso by late 2025 could shift policies. While supportive of innovation, the government prioritizes tax collection, possibly adding incentives for compliance.

Conclusion 

Mexico taxes crypto via ISR and VAT, enforced by SAT with advanced tools. Individuals must report gains, keep records, and file by April 30 to avoid fines or worse. Compliance is essential across all crypto activities. As regulations evolve, staying informed is key. A tax professional can simplify the process, ensuring legal crypto use without SAT interference.
