Key Takeaways in 60 Seconds
  • Core Concept: Modelo 720 is an annual informative tax declaration required by Spain’s Tax Agency (AEAT) for tax residents holding foreign bank accounts, financial assets, or real estate exceeding €50,000 in aggregate value across distinct asset classes as of December 31.
  • Why It Matters: Following the 2022 Court of Justice of the European Union (CJEU) ruling striking down disproportionate 150% fines, Modelo 720 remains fully mandatory but now conforms to standard statutory penalty limits, ensuring asset safety across borders.

Legal Nature: What Is Modelo 720 and Who Must File

Expats and international investors must maintain pristine compliance. Calculate your compounding wealth across international accounts using our compound interest calculator:

  • Obligated Taxpayers: Any tax resident individual or legal entity in Spain holding title, beneficial ownership, or authorized signature rights over qualifying assets abroad.
  • Purely Informative Return: Filing Modelo 720 creates zero direct tax liability. Capital gains, dividends, and interest generated by these foreign assets are reported separately on your annual IRPF income tax return.

The 3 Asset Categories and the €50,000 Reporting Threshold

Each asset class operates under autonomous valuation rules:

Reporting Obligation=∑AssetsCategory>€50,000  (Dec  31∨Q4  Avg)\text{Reporting Obligation} = \sum \text{Assets}_{\text{Category}} > \text{€}50{,}000\;(\text{Dec}\;31 \lor Q4\;\text{Avg})

If you hold €70,000 in foreign brokerage stocks (Category 2) and €12,000 in an overseas bank account (Category 1), you only report Category 2. In subsequent tax years, you only refile if your previously declared category grows by more than €20,000 or if an asset is closed.

Foreign Brokers and Neobanks: Who Triggers Modelo 720?

Investors must verify the legal custody domicile of every financial intermediary:

  • Interactive Brokers (Ireland - IBIE): Assets held under Irish custody. Portfolios exceeding €50,000 trigger Category 2 reporting, plus Category 1 if uninvested cash exceeds €50,000.
  • DEGIRO: Cash held in FlatexDEGIRO Bank AG (German IBAN). Portfolios exceeding €50,000 trigger Category 2.
  • Revolut / Trade Republic (Spanish Branches): Accounts operating with a verified Spanish IBAN (ES...) report data directly to AEAT and do not trigger Modelo 720.
  • US Accounts (401k, IRAs, US Brokerages): Full disclosure required under Category 2 if values exceed €50,000 equivalent in EUR.

Frequently Asked Questions (FAQ)

What if I hold €35,000 in a foreign bank and €40,000 in foreign stocks?

You do not need to file. Each asset category is assessed independently. Neither category reaches the €50,000 threshold.

Do I have to file Modelo 720 every single year?

No. You only refile if your declared category increases by more than €20,000, or if you dispose of or close previously declared assets.

Are cryptocurrency holdings declared on Modelo 720?

No. Overseas crypto assets are reported on a distinct return introduced in 2023: Modelo 721.

What are the consequences of a voluntary late filing without AEAT notification?

Filing voluntarily before any tax inspection incurs minimal administrative fines (typically €100 to €150) under standard General Tax Law provisions.
