Few Spanish tax obligations have generated as much fear as Modelo 720. Not without reason: for a decade, filing it late or with errors could trigger fixed fines of €5,000 per omitted or incomplete piece of data — with a €10,000 minimum — plus a penalty that could reach 150% of the value of undeclared assets. The Court of Justice of the EU ended that penalty regime in January 2022, ruling it disproportionate. What a lot of people get wrong from there is exactly what changed, and what didn’t.
What Modelo 720 requires (and still requires)
Any Spanish tax resident holding assets or rights abroad worth more than €50,000 in any of these three categories is required to declare them, each one assessed independently:
- Accounts at financial institutions located outside Spain.
- Securities, rights, insurance, and income held, managed, or earned outside Spain.
- Real estate and rights over real estate located outside Spain.
The filing window runs from 1 January to 31 March of the year following the tax year declared. Once filed for the first time, you only need to file again if the value of any category increases by more than €20,000 compared with the last filing, or if you cease to own an already-declared asset.
What changed in 2022, and what didn’t
The CJEU ruling specifically eliminated the disproportionate penalty regime — the fixed €5,000-per-item fines and the 150%-of-asset-value penalty — and Spain replaced it, through Law 5/2022, with a penalty regime brought in line with other similar informational returns: substantially milder, matching what any other late or incorrect informational filing gets penalised, not a punishment specifically designed to discourage holding assets outside Spain.
What the ruling did not touch is the filing obligation itself. It still exists, is still fully enforceable, and the tax authority still has access to information on foreign accounts and assets through automatic information-exchange mechanisms between EU tax administrations and broader international agreements — meaning the absence of a disproportionate fine doesn’t equal non-filing going unnoticed.
The mistake that still costs, even though it’s no longer disproportionate
The most common pattern behind a Modelo 720 problem isn’t deliberate concealment: it’s not knowing it applies. Someone who inherits a foreign account, keeps savings from a period living abroad, or has a family property in another country, is often unaware that, once they become a Spanish tax resident, those assets fall directly under this obligation if they exceed €50,000 per category.
The good practical news: regularising a situation like this before the tax authority detects it — filing the form late through a voluntary amended return — has far milder consequences than the alternative. Combining «obligation still in force» with «penalty no longer disproportionate» isn’t an invitation to ignore it; it’s simply one less reason to panic and one more reason to regularise it as soon as you realise it applies to you.
In the comments: if you registered late for Modelo 720 or regularised a pending situation after 2022, share what penalty you actually got and how the process went. It helps a lot in dispelling the disproportionate fear still circulating around this form, based on the old penalty regime that no longer exists.
