The universal one. It’s a transaction: you gain comfort but lose control, you save time but you have to extra without really knowing what for. The system itself tells you: “it could request additional information to transfer additional data to the return.” What data? Where does it come from? You don’t know. You accept it because it’s the only door.
For couples, the system guiding you step by step is an illusion. You go into the “Return sections,” you see hundreds of boxes, and the fear of making a mistake is paralyzing. The tool lets you “jot down notes” to help you, which is like a doctor giving you a notebook so you can write down the diagnosis yourself. What would be useful is an intelligent assistant, not a digital notepad. Before. Transfer to a Spanish account, to a foreign EU/SEPA one, or even to one outside that area (where you have to fill in international bank details that are almost impossible to obtain). If you have to pay, you can split it, set up a direct debit, or use Bizum. This supposed flexibility is a minefield: a mistyped IBAN, a wrong SWIFT-BIC code, and your payment is lost. The interface doesn’t verify this data against a reliable database; it only checks the format. The trust it demands is total.
The most dangerous thing is the delegation of knowledge. As the minimally complex case (foreign income, investments in crypto-assets, assets abroad), the system becomes hostile. It isn’t designed for the exception, but for the average. And no one is the tax average.
In the end, filing online is like driving a car with the hood welded shut. You go faster, but if something sounds strange, you can’t stop to look at the engine. Just cross your fingers and trust that the system’s designer thought about your specific case. And it almost never did.
