If you are living in Spain or planning to relocate, understanding Spanish international tax obligations is essential.
Becoming a tax resident in Spain may trigger reporting obligations regarding your assets held abroad. One of the most important is Modelo 720, the mandatory foreign asset disclosure form.
At CPG Abogados, we advise expatriates, investors, and international property owners on Spanish tax residency, foreign asset reporting, and pre-relocation tax planning to ensure full compliance with the Spanish Tax Agency.
WHAT IS MODELO 720?
Modelo 720 is an annual informative declaration submitted to the Spanish Tax Agency (Agencia Tributaria) to report certain foreign assets.
It is important to understand that:
- It is not a tax return.
- It does not automatically generate tax liability.
- It is a mandatory disclosure obligation.
- Non-compliance may trigger administrative penalties.
WHEN ARE YOU CONSIDERED A TAX RESIDENT IN SPAIN?
You are generally considered a Spanish tax resident if any of the following applies:
- You spend more than 183 days during the calendar year in Spain.
- Your main centre of economic interests is located in Spain.
- Your spouse and dependent children habitually reside in Spain.
If any of these criteria are met, Spain applies the principle of worldwide taxation, meaning you must declare your global income and certain international assets.
ASSET CATEGORIES TO REPORT
Foreign assets must be reported in three separate blocks:
- Foreign Bank Accounts – account balances and bank details.
- Foreign Securities and Rights – stocks, funds, insurance policies, etc.
- Foreign Real Estate and Property Rights – properties located abroad.
If the cumulative value of assets in a given category exceeds €50,000, all assets in that category must be declared.
MODELO 720 FILING DEADLINE
Modelo 720 must be filed annually between January 1 and March 31, reporting the status of foreign assets as of December 31 of the previous year.
For example, assets held on December 31, 2025 must be reported between January 1 and March 31, 2026.
Failure to file within the deadline may result in administrative penalties under the general Spanish tax regime. If you became a Spanish tax resident during the year, it is advisable to assess your reporting obligations well before the end of your first tax year.
IS IT REQUIRED EVERY YEAR?
Not necessarily.
A new filing is required only if:
- The value of a category increases by more than €20,000 compared to the last filing, or
- An asset previously declared is sold, cancelled, or transferred.
DOES MODELO 720 CREATE TAX LIABILITY?
Modelo 720 itself does not create a tax charge. However, the declared assets may have implications for:
- Personal Income Tax (IRPF – worldwide income taxation)
- Spanish Wealth Tax
- Temporary Solidarity Tax on large fortunes
- Future capital gains taxation
For this reason, proper international tax structuring before becoming a Spanish tax resident is essential.
TAX PLANNING BEFORE MOVING TO SPAIN
Many foreign nationals relocate without reviewing:
- International investment portfolios
- Foreign property holdings
- Corporate structures
- Life insurance wrappers and financial products
Pre-residency tax planning can significantly reduce future tax exposure, prevent compliance risks, and provide clarity on Spanish reporting obligations.
CONCLUSION
If you are a Spanish tax resident and hold foreign assets exceeding the legal thresholds, you are likely required to file Modelo 720.
Accurate and timely compliance is essential to avoid unnecessary risks with the Spanish Tax Agency and to maintain a secure tax position in Spain.
At CPG Abogados, we assist expatriates, investors, and international families with global asset analysis, pre-residency tax planning, and full compliance with Spanish reporting obligations.
If you are living in Spain or considering relocating, it is highly advisable to review your international tax position before the end of your first tax year as a resident.
