Every income tax campaign the same scene is repeated: that client arrives with a face like “I haven’t sold anything”, convinced that his cryptocurrency operations are not taxed because he hasn’t withdrawn a single euro to his bank account. And that is the beginning of our fiscal tragicomedy…
🎬 Primer acto: el mito del HODL eterno
“But if I just traded ETH for USDC?” “If it’s all inside Binance, why does the IRS care?” Spoiler: it cares. A lot. Because, surprise, the passage from a crypto to a stablecoin is considered a patrimonial transfer. In plain English: it’s like selling.
And here comes the scare. What for the trader is just “switching to a more stable currency”, for the Tax Agency is a taxable event like a cathedral.
⚖️ Segundo acto: la doctrina fiscal europea (una tragicomedia en varios idiomas)
Although it may seem like a European mess worthy of Kafka, the truth is that most EU member countries apply the same criteria: converting a cryptoasset to a stablecoin (such as USDT, USDC, DAI…) is like selling it for euros. Whichever way you look at it, Treasury always wins.

😱 Tercer acto: el susto de la cuenta de resultados
When the client sees the tax summary and the amount to be paid after 2000 trading operations with stablecoins, his face pales. Because the fiction of stability becomes an avalanche of transmissions subject to IRPF.
“But I was just protecting my profits!”
-Yeah, right… and you’ve inadvertently generated a taxable income that makes you laugh at Wall Street Bets!
🧠 Moraleja (fiscal y emocional)
The use of stablecoins in internal trading operations is not innocent. Even less so is it invisible to the tax authorities. In fact, it is no longer a matter of “taking out FIAT” as a threshold: the taxable event is in the conversion itself.
🧩 Therefore, having a clear tax strategy, annual simulations, and professional advice is as important as choosing the right token.
