Spain's DD1 form and modelo 720: two different filings for foreign accounts

Reporting foreign accounts: the Banco de España's DD1 form and the modelo 720

Opening an account abroad is not a crime. Failing to declare it, under the current rules, can cost you dearly. And the detail almost nobody gets right is that there are two separate obligations that are constantly confused: one goes to the Banco de España and the other to the Spanish Tax Agency. The first is Circular 3/2006, which requires reporting the opening and closing of accounts abroad, as well as their balances and transactions. The second is the modelo 720, filed with the Tax Agency when your total assets and rights abroad exceed €50,000.

The most common mistake is believing that below that threshold there is nothing to do. That is not the case: the €50,000 threshold exempts you from the 720, but not from the Banco de España form. The confusion comes from mixing up the two filings, and from the fact that the authorities themselves do not always clarify which one applies.

What the DD1 form is and when it must be filed

The DD1 is the document used to declare the opening or closing of an account abroad. The DD2 covers transactions. The obligation stems from Circular 3/2006 of 28 July, and the deadline for filing the opening is one month from the date the account was peine. For transactions, the rule sets thresholds: the total must exceed €600,000 per year or €3,000,000 per month before reporting becomes mandatory.

Here is the catch: many people with modest accounts believe they are exempt from everything. They are only exempt from the transaction reporting. The opening, however, must always be reported. And if the month has passed, the situation does not fix itself.

The modelo 720: what it is and why it intersects with income tax

The modelo 720[/B> is the informative declaration of assets and rights located abroad. It is filed with the Spanish Tax Agency and, under the rules cited, its exceptional filing period was during the months of March and April. The threshold that triggers the obligation is holding more than €50,000 in total. Below that figure, there is no need to file it.

Here comes the point that causes the most anxiety: the Tax Agency has confirmed that, once the 720 has been filed, it can check whether the declared assets match declared income. In other words, the form is not an isolated formality: it opens the door for the Tax Agency to review whether that money held abroad was declared at the time in personal income tax. If it was not declared, it can be regularised. And if it is regularised, payment is due.

Penalties: what the law says and what remains unclear

Ley 19/2003, on capital movements and economic transactions with abroad, sets out the penalty regime. For late filing without a prior request from the authorities, fines are tiered: up to €300 if no more than six months have passed, with a minimum of €150. Beyond that, things escalate.

What remains unresolved is whether that law is still the one governing penalties for failing to report to the Banco de España, or whether the anti-fraud law has updated it. Some argue that penalties lapse after one year, which in practice would leave very late notifications unpunished. Others warn that this would be a contradiction: if you are required to report, it makes no sense for the obligation to disappear on its own over time. The discrepancy remains open.

The real antiestéticar: that the 720 will be used to collect tax for previous years

Part of the analysis holds that the tightening of the rules is not only aimed at organising information, but also at opening the door to regularisations of past tax years. The reasoning is simple: if you declare an account you had failed to declare for years, the Tax Agency can check whether the interest it generated was taxed at the time. If it was not, you must pay the difference plus surcharges.

Against that, another view defends that declaring is always better than not doing so. The fine for filing late is capped; the penalty for concealment, when you are caught, is not. And with international banking data exchanges, the likelihood of being caught without having declared keeps rising.

Broker accounts: the doubt the Banco de España resolved by phone

A recurring question is whether securities and derivatives accounts with foreign brokers fall under the DD1. The answer given by the Banco de España's department for economic transactions with abroad was that they do not: those accounts are not considered bank accounts and do not need to be declared via the DD1 form. The clarification matters because many investors operate with brokers outside Spain and assumed the opposite.

How to file and where to send it

The process is not convenient. The DD1 and DD2 forms cannot be downloaded directly: you must request them by email from the Banco de España, which sends them blank by post. They are then filled in and sent back. There is also an online route with a digital certificate or electronic ID, although it does not always work: some users have reported loading errors on the Banco de España website when trying to file.

The postal address of the head offices is C/ Alcalá, 48, 28014 Madrid, and the enquiries phone number is 91 338 50 00. For specific questions about the procedure, the Banco de España has contact email addresses for its economic transactions with abroad department.

Is it worth regularising an old account that was never reported? The answer depends on how much is in it, how many years have passed and whether that interest was declared at the time. Nobody gives an exact figure, and that is precisely the part that remains unresolved.
