If you are a foreign resident in Spain or own assets abroad, it is crucial to stay compliant with Spanish tax regulations. Two key declarations you must be aware of are Modelo 720 and Modelo 721. These forms are mandatory for reporting foreign assets and cryptocurrencies, respectively. Failing to submit them on time may lead to significant penalties.
What is Modelo 720?
Modelo 720 is a mandatory tax declaration for individuals and entities with assets outside of Spain exceeding €50,000. These assets include:
- Bank accounts
- Real estate properties
- Investments (stocks, bonds, and shares)
- Life insurance policies
Deadline: March 31st of each year
If you have previously submitted Modelo 720, you only need to file it again if the value of your declared assets has increased by more than €20,000 or if you have disposed of any of them.

What is Modelo 721?
Modelo 721 is a newer tax declaration specifically for individuals who own cryptocurrencies in foreign exchanges. It applies if your cryptocurrency holdings abroad exceed €50,000 as of December 31st of the fiscal year.
Deadline: March 31st of each year
If your cryptocurrency holdings change significantly in the future, you may need to update your declaration in subsequent years.
Consequences of Non-Compliance
Failing to submit these declarations or providing incorrect information can result in severe fines. Spanish tax authorities impose penalties for:
- Late submission
- Inaccurate or missing information
- Non-declaration of eligible assets
