Educational content only. This is not tax, legal, or investment advice. Mexico rules are applied by the SAT under the LISR and related guidance — confirm current positions with a Contador Público / local tax advisor before filing.
Mexico does not have a standalone “crypto tax code.” Residents still face real obligations through the Ley del Impuesto Sobre la Renta (LISR) and the SAT. This CryptoTax Digest guide focuses on the 2026 practical picture: progressive ISR, FIFO, why a BTC→ETH swap can be a permuta (taxable disposal), and the typical 30 April annual filing window.
Essentials at a glance
| Topic | 2026 snapshot (verify locally) |
|---|---|
| Legal hook | No dedicated crypto CGT statute; LISR + SAT practice |
| Asset view | Often treated as intangible / virtual assets |
| Taxable event | Enajenación (sale, spend, many swaps) |
| Rate | Progressive ISR roughly 1.92% → 35% on relevant income |
| Cost basis | Commonly implemented with FIFO + MXN FX |
| Crypto↔crypto | Often analyzed as permuta (taxable) |
| Annual return | Typically due by 30 April of year N+1 |
No dedicated crypto law — LISR still applies
Fintech recognition of virtual assets does not create a special flat “Bitcoin rate.” For many individuals, gains sit under enajenación de bienes mechanics: you realize when you dispose, not when you merely hold.
Intangible assets
Crypto is generally not MXN legal tender. For tax analysis, treat it as property whose disposal can create taxable income measured in Mexican pesos.
Enajenación de bienes
Typical triggers:
- Sell crypto for MXN / USD / other fiat
- Pay for goods or services with crypto
- Swap one crypto for another (see permuta below)
Transfers between wallets you control are usually not disposals if beneficial ownership does not change — but document them so they are not mistaken for sales.
FIFO cost basis
Mexican practice for crypto cost tracking commonly leans on FIFO (first-in, first-out). Without acquisition dates, quantities, and MXN values, your gain calculation collapses.
Why MXN FX matters
Gains are computed in pesos. Use a consistent, defensible FX source for the day of each taxable event (many practitioners reference Banco de México FIX / SAT-accepted rates — confirm what your advisor uses). Mixing USD screenshots and MXN bank deposits without a FX trail is a frequent audit headache.
Permuta: every crypto↔crypto swap can be taxable
This is the surprise angle for traders who only watch bank withdrawals. Under Mexican tax concepts, a permuta (swap) can be treated as disposing of one asset to acquire another. Practically: BTC → ETH, ETH → USDT, or altcoin rotations may each crystallize gain or loss even if you never touch pesos.
Common mistakes
- Reporting only fiat off-ramps and ignoring swaps
- Using “last price on CoinGecko” inconsistently across the year
- Assuming P2P MXN trades are invisible — platforms and counterparties still leave trails
- Treating stablecoin rotations as “not real trades”
Staking, mining, airdrops
Rewards are often discussed under Otros Ingresos concepts: value at receipt (MXN on day J) can matter, with a later disposal creating a second calculation. Doctrine and facts matter — habitual mining or trading may push you toward business-like treatment.
Strict vs deferred interpretations
Some software defaults and informal guides treat certain passive receipts as non-taxable until sale (cost basis zero or deferred). SAT-strict compliance often expects manual acquisition values when rewards are income at receipt. Do not assume a product default equals Contador guidance — document your chosen method and stay consistent.
Declaration calendar
For individuals, the annual income-tax return that includes crypto gains is commonly filed in April, with a widely cited deadline of 30 April for the prior calendar year. Confirm the exact SAT calendar for your RFC situation (employees vs multiple income sources, provisional payments, etc.).

FAQ
Is holding Bitcoin taxable in Mexico?
Usually not by itself. Taxation typically follows disposal (enajenación) or income characterization of rewards.
Are crypto↔crypto trades taxable?
Often yes, as permuta / dual disposal analysis. Do not wait for a bank deposit to start tracking.
What rate do I pay?
There is no single “crypto rate.” Net gains feed progressive ISR brackets (commonly cited up to 35%). Your total annual income matters.
When is the deadline?
Annual filing is commonly due by 30 April of the following year — verify on SAT for your case.
