residency in Spain is a key factor in the taxation of individuals who live or work in the country. Increasing globalization and international mobility have generated numerous tax conflicts, where two or more countries may consider the same individual a tax resident, leading to double taxation and increasing the taxpayer's tax burden.
At Resitax, expert tax advisors, we explain how to determine tax residency in Spain, what criteria the Tax Agency applies, and how to avoid international double taxation using current regulations and Double Taxation Agreements (DTAs).
Taxation Models Around the World: How Do Countries Determine Tax Residency?
The most common taxation model globally is based on the individual's tax residence, which means that:
- Tax residents are taxed on all their worldwide income.
- Non -residents only pay taxes on income generated within the country.
However, there are other, less common models:
- Some countries do not impose income tax on individuals.
- Others only tax income earned within their territory.
- The United States taxes its citizens regardless of where they reside.
- There are special limited taxation regimes for non-habitual or temporary residents.
Tax Residency in Spain: Key Criteria for Determining It
Spain, like most European countries, follows the tax residency. However, this can lead to conflicts when another country also considers a person to be a resident.
"To find out the official criteria regarding tax residency in Spain, you can consult the Tax Agency's guide here."
The main criteria for determining tax residency in Spain include:
- Stay in the country: More than 183 days a year in Spanish territory.
- Center of economic and vital interests: Where economic activities and the family nucleus is located.
- Nationality: Used as a residual criterion or tie-breaking rule in certain cases.
Tax Residence in Spain according to the LIRNR
According to Article 6 of the LIRNR, a person is considered a tax resident in Spain if they meet any of these criteria:
1. Staying in Spain for more than 183 days
- Sporadic absences are included , unless the individual proves tax residence in another country .
- If a taxpayer has been in Spain for 150 days without proving residence in another country, they will be considered a Spanish tax resident.
2. Center of Economic Interests
- It is evaluated country by country, not in relation to the rest of the world.
- Not only income is considered, but also assets and expenses.
- The Law on Financing of the Autonomous Communities uses a similar concept to determine tax residency within Spain.
3. Family Ties
- If the spouse is not legally separated and the minor children reside in Spain, the taxpayer's tax residence is presumed
Double Taxation Agreements (DTAs): How to Avoid Taxation in Two Countries
Double taxation agreements (DTAs) are bilateral treaties designed to avoid double taxation. Spain has signed agreements with countries such as:
- Germany (July 30, 2012)
- Austria (December 20, 1966)
- Switzerland (March 3, 1967)
Although double taxation agreements (DTAs) do not define residency, they establish tie-breaking rules to resolve conflicts when two countries consider a person to be a tax resident.
Tie-breaking Rules in Double Taxation Agreements: How to Determine the Correct Tax Residency
When there is a conflict of dual residence, the IDCs apply these hierarchical criteria:
- Permanent residence: The country where the person has a home available.
- Center of vital interests: Where you have the strongest personal and economic ties.
- Usual residence: Country where the taxpayer lives most regularly.
- Nationality: If the conflict persists, nationality is used as the final criterion.
- Friendly agreement: Ultimately, the tax authorities of both countries must negotiate.
To apply for a CDI, the taxpayer must obtain a tax residency certificate issued by the Tax Administration of the country in question.
Supreme Court ruling STS 778/2023: A Key Precedent in Tax Residence
Supreme Court ruling STS 778/2023 has been fundamental in matters of tax residency and double taxation in Spain. Some key points:
1. Validity of Tax Residency Certificates
- Spain cannot question the validity of a tax residence certificate issued by another country.
- Example: A certificate issued by the U.S. IRS must be accepted without objection.
2. Center of Vital Interests: Expansion of the Concept
- It should not be evaluated solely based on assets or income obtained in Spain.
- Family, social, and professional relationships should also be considered .
3. Burden of Proof of Tax Residency
- The taxpayer must prove their residence in another country, but the Tax Administration must rely on objective evidence.
4. Application of the ICD Tie-Breaking Rules
- Before applying Spanish legislation, the rules of the Double Taxation Conventions (DTCs) must be respected.
Other Key Aspects in Spanish Jurisprudence
- Regime for expatriates: Possibility of issuing tax residence certificates by the Ministry of Finance.
- Flexibility in proof: Some courts accept bank statements and bills as proof of residence. However, the Tax Authority usually requires a certificate from the relevant tax authority.
- Countries considered tax havens: Stricter proof of tax residency is required, such as staying for more than 183 days.
- No splitting of tax periods: Spanish law does not allow dividing the fiscal year due to changes of residence.
The Importance of Good Tax Advice
Since the tax system in Spain is based on tax residency, it is essential to have a clear definition and avoid broad interpretations by the Administration.
To avoid double taxation problems , it is essential to:
- Having good tax advice.
- Know and correctly apply the tie-breaking rules of the CDI.
