The problem
If you are a tax resident in Spain and hold financial assets, securities, or real estate outside the country above certain thresholds, you are required to file an annual informational declaration known as the Modelo 720 with the Spanish Tax Agency (AEAT). Many new residents — particularly those who have recently relocated through the Digital Nomad Visa, the Non-Lucrative Visa, or who have become Spanish tax residents after years of part-time presence — are entirely unaware of this obligation until they receive a letter from the AEAT or encounter the issue during a tax compliance review. The consequences of non-compliance can range from administrative penalties to a full tax investigation of the origin of the undeclared assets. While the original disproportionate penalty regime was struck down by the Court of Justice of the European Union in 2022, the obligation to declare remains fully in force and penalties for non-compliance, though now proportionate, are still significant.
Our solution
At BMC we specialise in the Modelo 720 for international clients who have recently become Spanish tax residents and for long-term residents who have never filed or have filed incorrectly in previous years. We conduct a full inventory of your overseas assets, determine in which categories the 50,000-euro threshold is exceeded, calculate the values to declare, and file the return within the legal deadline. For clients with previous years of non-compliance, we assess the advisability of voluntary late filing under the new proportionate penalty regime and advise on coordinating the 720 with your annual income tax return and wealth tax obligations.
How we do it
Asset inventory and threshold analysis
We catalogue all your overseas financial holdings as of 31 December of the relevant tax year: bank accounts (current, savings, investment, and credit), securities (shares, investment funds, ETFs, bonds, listed and unlisted), life insurance policies with surrender value, annuities, and real estate held directly or through ownership structures. We determine whether the 50,000-euro threshold is exceeded in each of the three independent categories.
Obligation assessment and filing strategy
We determine the obligation category by category and year by year. For clients with past non-compliance, we assess the practical risk of the AEAT already holding the information through automatic exchange of tax information (CRS/FATCA) and compare it against the cost of voluntary late filing under the current penalty regime.
Preparation and timely filing
We prepare the Modelo 720 with all required data: financial institution names and BIC/IBAN codes, asset types, ownership percentages, values, and acquisition dates. We file electronically before the 31 March deadline for the previous tax year.
Coordination with income tax and wealth tax returns
We verify that the information in the Modelo 720 is consistent with what is reported in your Spanish income tax return (IRPF or IRNR) and your wealth tax return (Impuesto sobre el Patrimonio), avoiding inconsistencies that could trigger a compliance review. We also advise on the Modelo 721 for cryptocurrency assets held on foreign exchanges.
I had lived in Spain for two years and had no idea about the Modelo 720. My Swiss investment account was well above the threshold. BMC assessed the situation, filed three years of late declarations under the new penalty framework, and the total cost was a fraction of what I had feared. Completely handled.
What is the Modelo 720 and why does it matter?
The Modelo 720 is an informational tax declaration filed annually with the Spanish Tax Agency (AEAT) by Spanish tax residents who hold overseas assets above specified thresholds. It is not a separate tax — it does not directly generate a payment obligation. Its purpose is transparency: to allow the Spanish tax administration to cross-reference declared overseas assets against income and wealth reported in other filings, deterring the undeclared accumulation of assets abroad.
The declaration is structured around three independent categories, each with its own 50,000-euro threshold:
Category 1 — Accounts in foreign financial institutions: Current accounts, savings accounts, investment accounts, credit accounts, and any other account in which you hold title, beneficial interest, are an authorised signatory, or have power of disposal.
Category 2 — Securities, rights, insurance, and annuities held abroad: Shares (listed and unlisted), investment funds (including SICAV and ETF), bonds, structured products, life insurance policies with surrender value, capitalisation contracts, and temporary or lifetime annuities deposited or managed by entities outside Spain.
Category 3 — Real estate situated outside Spain: Property held directly in your name, or indirectly through rights in rem or through participations in entities whose principal asset is real estate located abroad.
The 2022 CJEU ruling: a turning point
When the Modelo 720 was introduced in 2013, the penalty regime was notoriously harsh: penalties of up to 150% of the undeclared asset value, with no statute of limitations in certain cases. The European Commission challenged this regime as incompatible with EU law, and in January 2022 the Court of Justice of the European Union agreed, ruling in case C-788/19 that the disproportionate penalties violated the fundamental freedoms of the European Union.
The Spanish legislature reformed the penalty regime in 2023, bringing it in line with comparable informational declarations. The practical consequence is that voluntary late filing of previous years’ declarations is now a viable and much less costly option than it was before 2022.
Coordination with Wealth Tax and Income Tax
The information disclosed in the Modelo 720 is used by the AEAT as a baseline for verifying the consistency of your Wealth Tax and income tax filings. If you declare overseas securities in the Modelo 720, the capital gains, dividends, and interest generated by those securities should be declared in your income tax return. Inconsistencies between these filings are one of the most common triggers for a AEAT compliance review.
For clients who have recently relocated to Spain and are navigating the Beckham Law regime — where foreign-source income may be exempt — the Modelo 720 interacts differently with the income tax obligation, and specialist advice is essential. We provide this as part of our international tax advisory service and coordinate it with non-resident tax obligations where relevant.
