Among foreign residents in Spain, few pieces of paper carry the reputation of the Modelo 720. For years it was the declaration that turned honest people into severe defaulters over a filing error, and although its worst features have been struck down, it remains a trap for the newly arrived wealthy resident who does not know it exists. Anyone moving to Spain with assets abroad, which describes almost every wealthy mover, has to understand it before their first Spanish tax year closes.
What it requires
The Modelo 720 is an informative declaration: a Spanish tax resident must report assets held abroad above defined thresholds, across categories including accounts, securities and real estate. It does not itself levy a tax; it tells the Spanish authorities what a resident owns outside Spain. For a wealthy person with international accounts, investments and property, the obligation is broad and the detail demanding.
One form carries three separate obligations. Accounts with banks and credit institutions abroad fall under article 42 bis of the general tax management and inspection regulation, securities, policies and annuities under its article 42 ter, and real estate under its article 54 bis, with the parent duty in the eighteenth additional provision of the General Tax Law. Each block is a distinct obligation on one return, and thresholds and penalties are measured block by block, not across the balance sheet.
The threshold in each block is 50,000 euros, applied in aggregate rather than to any single asset. Cross it and every asset in that block must be reported. Values are taken at 31 December for accounts and securities, with accounts also reporting the final quarter’s average balance. Real estate is the exception: article 54 bis reports the acquisition value of the property, and the threshold measures that figure together with the other values the article specifies, so 31 December fixes what was held. Filing runs from 1 January to 31 March of the following year.
The rule that catches people is repeat filing. Once a block has been declared, a further return is due only where its aggregate has risen by more than 20,000 euros above the figure behind the last one, or where the person ceased during the year to hold something previously declared. A resident may file once and legitimately not file again for years, which is how it drops out of mind.
Why it became infamous
The notoriety came from the penalties. In its original form, failure to file correctly, even a late or incomplete declaration of assets on which no tax was owed, could trigger penalties so severe they exceeded the value of the assets themselves, together with the treatment of undeclared foreign assets as unjustified gains without time limit. Foreign residents who had done nothing wrong beyond a paperwork mistake faced ruinous consequences, and the regime became a byword for disproportion.
It taxed nothing and threatened everything. A late form about assets on which no tax was due could cost more than the assets themselves.
Three pieces of machinery produced that result, and they ran concurrently. Undeclared foreign assets were treated as unjustified capital gains under article 39 of the personal income tax law and attributed to the earliest year still open, with no practical route to plead limitation. A proportional fine of 150 per cent of the tax so calculated followed under the first additional provision of Law 7/2012. The reporting failure carried fixed fines of its own, at 5,000 euros per item with a floor of 10,000 euros per block and no ceiling.
The European court stepped in
The European Court of Justice found the penalty regime disproportionate and contrary to European law, and Spain was required to reform it. The crushing penalties and the unlimited look-back were dismantled, and the sanctions were brought back toward proportion. This was a genuine and important correction, and it removed the worst of the danger.
In Commission v Kingdom of Spain, Case C-788/19, decided on 27 January 2022, the Court held that Spain had breached Article 63 of the Treaty and Article 40 of the Agreement on the European Economic Area on three counts: treating non-compliance as producing unjustified capital gains with no possibility in practice of benefiting from limitation; the 150 per cent fine, applicable concurrently with the flat-rate fines; and flat-rate fines disproportionate to those for similar infringements in a purely national context, with no cap on the total.
What the Court declined to do matters as much. It accepted that effective fiscal supervision and the prevention of tax evasion are overriding reasons in the public interest, and held legislation of this kind appropriate for attaining them. The breach lay in the consequences attached to the failure, not in the requirement to report.
What Spain actually changed
The correction arrived in Law 5/2022 of 9 March, an act otherwise concerned with hybrid mismatches. Its fourth final provision rewrote the eighteenth additional provision of the General Tax Law, keeping the categories of information and deleting the penalty section beneath them. Its fifth final provision rewrote article 39 of the personal income tax law, so that an unjustified gain is integrated in the period it is discovered unless the taxpayer proves ownership from before the limitation period. Its repealing provision struck out the first and second additional provisions of Law 7/2012, where the 150 per cent fine lived.
The law was published on 10 March 2022 and took effect the following day. Any account of the Modelo 720 that assumes the old sanctions still apply describes a regime that ceased to exist more than four years ago, and the reputation the form carries in expatriate conversation is one it no longer earns. A resident who believes the form can bankrupt him makes worse decisions than one who knows its real cost.
The penalties that apply now
With the special regime gone, the form falls back on the ordinary penalty rules of the General Tax Law, as the tax agency says in its published guidance on penalties and effects. Failing to file on time a return that causes no loss to the treasury is penalised under article 198 at 20 euros for each item or set of items, with a floor of 300 euros and a ceiling of 20,000. Filing late but before any request from the authorities halves the penalty and both limits.
Filing on time but incompletely falls under article 199. Where the data are monetary the penalty is proportional: up to 2 per cent of the amounts omitted or misreported with a floor of 500 euros, graduated at 0.5, 1, 1.5 or 2 per cent as those amounts exceed 10, 25, 50 or 75 per cent of what should have been declared. The penalties apply independently to each information obligation, and the ceiling is per block; before 2022 the floor was 10,000 euros per block with no ceiling at all.
But the obligation remains
What the court did not do was abolish the declaration. The Modelo 720 still exists, the obligation to report foreign assets still applies, and penalties for non-compliance, now proportionate, still follow. A newly arrived wealthy resident who assumes the whole thing went away when the penalties were struck down is mistaken, and the mistake is one the Spanish authorities are equipped to find, because they receive information about foreign accounts automatically.
That is the point newcomers underestimate. Spain receives account data on its residents under the exchange arrangements set out in our note on the Common Reporting Standard, and comparing what arrives against what was reported is screening, not investigation. It is cheap, it runs on every file, and requires no prior suspicion.
The perimeter is wider than ownership. The obligation reaches representatives, authorised signatories, beneficiaries, holders of powers of disposal and beneficial owners as defined in the anti-money-laundering law, extending to accounts in the name of persons or arrangements constituted abroad. A resident with signing authority over a family company account abroad is inside the perimeter while owning none of it. The reporting position therefore belongs in the design of cross-border structures across the Netherlands, Luxembourg and Spain, not in the cleanup afterwards.
Crypto is inside the perimeter now
The category added since the reform is virtual currency. Article 42 quater, inserted by Royal Decree 249/2023 and in force from 25 April 2023, requires residents to report virtual currencies situated abroad, meaning those held by a party safeguarding private cryptographic keys for third parties that is not itself obliged to report to the Spanish authorities. The threshold is the familiar 50,000 euros on year-end value, with the same 20,000 euro rule for repeat filing.
It is reported separately on Modelo 721, approved by the ministerial order of 26 July 2023 and first applied to the 2023 year, filed between 1 January and 31 March 2024. Each coin is reported in its own units and in euros, valued on the 31 December quotation of the principal trading platforms or price-tracking sites or, failing that, on a reasonable estimate of market value, with the quotation or value used stated in the return.
The test is custody, not geography. The duty attaches to coins in the keeping of a third party safeguarding keys on the holder’s behalf, which is what a foreign exchange does and what a wallet whose keys the holder controls does not. A balance sheet spanning both has to be separated before the threshold is calculated, which matters most to the tech and crypto wealthy moving to Spain with holdings that were never in a bank.
Handle it as part of arriving
The sensible approach for anyone becoming a Spanish tax resident is to treat the Modelo 720 as a standard part of arriving, identified and prepared before the deadline rather than discovered after it. For a wealthy person with a complex international balance sheet, that means mapping the reportable assets in advance, which is naturally part of the wider move we describe in our notes on Spanish tax residence and the Beckham law. The declaration is no longer a threat to be feared; it is an obligation to be met, and the only people it still catches are the ones who did not know it was there.
One exemption is worth settling before that year closes. A resident who has elected the impatriate regime of article 93 of the personal income tax law is not required to file the Modelo 720, because that regime taxes him under non-resident rules rather than on worldwide income, and the tax agency confirms it in its guidance on who must declare. The exemption is strictly personal. It does not extend to a spouse or children, who are obliged in their own right if Spanish tax resident, and it expires with the regime, at which point the full obligation begins against the assets as they then stand.
