CRYPTO & TAXES
Learn crypto — including the part nobody teaches: the taxes
A practicing chartered accountant explains the technology and, above all, how it affects you tax-wise in Mexico. No return promises, no influencer language.

The technology
To make good tax decisions you first need to understand what you are actually using.
The blockchain, without the mystery
Think of it as a public, shared ledger that nobody can alter. Every transaction is recorded and anyone can review it; no one can erase it or rewrite the past.
How it works, roughly
The network keeps a copy of that ledger on thousands of computers. To move funds, the network verifies and validates the transaction; once confirmed, it joins the shared history.
Your keys, your signature
A wallet does not “store” coins: it stores the keys you sign movements with. Lose the keys and you lose access. Whoever controls the keys controls the funds.
Exchanges vs. self-custody
On an exchange, a third party holds the funds for you (convenient, but you depend on that platform). With self-custody you control the keys: more control, more responsibility.
Stablecoins
Cryptocurrencies designed to hold a stable value, usually pegged to the dollar. They are widely used to move value and to pay; their tax treatment does not change just because they are “stable”.
Why this matters tax-wise
Each of these pieces — custody, keys, platforms — leaves a different trail, and each trail translates into different tax obligations.
Module 2
Taxes in Mexico
This is where most crypto courses go quiet. These are the general rules we apply every day.
No crypto-specific tax law
The Fintech Law defines “virtual assets”, and for tax purposes the SAT treats them as intangible property: a sale is taxed under the general disposal-of-assets (enajenación de bienes) rules.
What counts as a taxable event
Buying and holding does not. Selling, swapping (including crypto-to-crypto) or paying with crypto does: each of those can be a disposal or a barter.
Cost basis is everything
The gain is the sale price minus what it cost you, adjusted for inflation (INPC) between purchase and sale. Without records backing your cost, the gain can be overstated — and so can the tax.
Rates and regimes
Occasional gains stack on top of your other income and are taxed on the progressive ISR scale. If you trade frequently, it can be treated as business activity. The annual movable-goods exemption and simplified regimes depend on your profile — ask us in your consultation.
Platforms abroad
Trading on exchanges outside Mexico does not free you from filing in Mexico. Automatic information exchange between countries is advancing and platforms report more every year.
When and how it is filed
Occasional gains go on the annual return, due by April 30 of the following year. Everything is valued in pesos at the official exchange rate (Banxico).
The part nobody tells you
How crypto income fits with your tax residency, your other income and your home country. That is exactly what we review in a consultation.
This content is general and educational. Your regime, rates and strategy depend on your specific case — we define them in your consultation.
Module 3
What to watch out for
No alarmism and no promises. Just the real risks we see in practice.
Scams and pyramid schemes
“Guaranteed” returns, pressure to invest now and social pressure are red flags, not arguments. If it sounds too good to be true, it probably is.
Rug pulls and unsupported tokens
Projects that vanish with the money, or never had a real product. Popularity on social media is not a guarantee.
Phishing and key theft
Emails, messages and sites that imitate your exchange or wallet to capture your keys or your password. No legitimate party ever asks for your private keys.
Custody risk
Lose the keys and you lose the money: no bank, no reversal. Self-custody demands more care, not less.
Volatility
The price can move sharply in a short time. Do not plan tax bills or real commitments around an assumed future value of your portfolio.
The tax blind spot
The most expensive risk is usually not the market, but not filing. An undocumented deposit, a missed annual return or an unproven cost become a problem with the tax authority — not with the market.
Stablecoins that were not stable: the UST case
In May 2022, UST (Terra) —an “algorithmic” stablecoin backed by an algorithm rather than dollar reserves— lost its dollar peg and crashed together with its sister token LUNA. Nearly $45 billion was wiped out in a week and the company ended up bankrupt; the token no longer functions as a stable dollar today. The lesson: “stablecoin” is a design promise, not a guarantee — check the real backing before you trust it.
Module 4
Platforms, networks, and how your money gets in and out
Two words explain almost everything: on-ramp (the way in: pesos to crypto) and off-ramp (the way out: crypto to pesos). Here is the map, in plain language.
On-ramp: pesos into crypto
That is what the ways in are called. Buying on a Mexican exchange via SPEI, from the Mercado Pago app, or inside Telegram with a card through third-party providers. Each path has its own fees and timing.
Off-ramp: crypto back into pesos
That is what the ways out are called. Selling on an exchange and withdrawing to your CLABE via SPEI, peer-to-peer (P2P) trading, or paying directly with crypto. Remember: each exit can be a taxable event (Module 2).
The network matters as much as the coin
The same USDT exists on several networks (Ethereum, Tron, Solana and more). Sending and receiving must use the same network: pick the wrong one and the funds can be lost with no reversal. Network fees are paid in that network’s native coin, not in USDT.
The main chains, one line each
Bitcoin: the first and best known, today mostly a store of value. Ethereum: the smart-contract network where most stablecoins were born, with higher fees. Tron: the favorite for moving USDT across Latin America because it is cheap. Solana: fast and inexpensive. TON: the network behind Telegram. Cardano: a proof-of-stake network with a peer-reviewed-research approach; its coin is ADA and it lets you stake without locking your funds.
USDT and USDC: the stablecoins that are actually used
USDT (Tether) is the largest stablecoin and the most used across Latin America; USDC (Circle) is known for its reserve reporting and institutional adoption. Both are dollar-pegged and live on several networks: when choosing one, check who issues it, who audits its reserves, and which network you will move it on. Together they dominate the stablecoin market.
Operators people actually use in Mexico
This is not a recommendation: it is a map. Each person chooses based on fees, custody, and what they need it for.
Bitso
Mexican exchange: buy and sell crypto for pesos via SPEI, withdraw to your CLABE, and hold stablecoins. Its transaction statements are your best evidence for bookkeeping and cost basis.
Bitso Business
The enterprise version: local collections and payments (SPEI), mass payouts, a multi-currency account, an OTC desk, and an API to integrate collections. It includes MXNB, a peso-backed stablecoin issued by Juno (a Bitso company) that is minted via SPEI and redeemed back to pesos.
Mercado Pago — Meli Dólar (MUSD)
A 1:1 digital dollar inside the Mercado Pago app in Mexico: bought with pesos in the app with no extra fee (per their official page) and usable to pay on Mercado Libre. Custody is handled by Ripio. Probably the closest on-ramp for someone who has never used an exchange.
Telegram — Wallet and TON
A wallet built into the chat: send and receive USDT, TON and BTC, and transfers between Telegram users generally carry no network fee. You can buy with a card through third-party providers (MoonPay, Banxa, Transak), which do charge fees, and self-custody is available via TON Space. Careful: fake bots are the main source of losses — use only the official wallet or well-known wallets.
How to choose
Always compare: buy/sell and network fees; whether the platform issues statements for your bookkeeping; who holds your funds (you or the platform?); and how easy it is to exit when you need to. Information verified in September 2026 on each platform’s official pages: fees and features change, confirm at the source.
We mention these platforms for informational purposes, not as a recommendation to use or invest. Each operates under its own terms and fees.
