France-Spain tax treaty: how to avoid double taxation

The tax convention between France and Spain, signed on October 10, 1995, determines which of the two States can tax each category of income, and eliminates double taxation by two mechanisms: tax credit and exemption with progressivity. It applies to income tax, corporate tax and wealth tax.

When a taxpayer receives income in one country (source state) but resides in the other (state of residence), the risk of being taxed twice on the same income is real. Here, category by category, is what the agreement provides:

The principle of tax residence

The convention establishes that it is the tax residence which determines which state has the right to tax your worldwide income. If you are a tax resident in Spain, you must declare all of your income (French and Spanish) to the Hacienda. Spain will then grant you a mechanism to neutralize the tax already paid in France.

Spanish tax residence is determined according to three alternative criteria: presence in the territory for more than 183 days in the calendar year, center of economic interests in Spain (main place of work or activity), or center of vital interests (family, main housing). A single criterion is enough to be considered a Spanish tax resident.

The two methods to eliminate double taxation

Depending on the nature of the income, the Franco-Spanish convention provides for two distinct methods:

1. The imputation method (tax credit)

This is the most common method, applicable in particular to dividends, interest and royalties. Spain calculates the tax on your overall income, then deducts from this tax the amount you have already paid in France, up to the limit of the Spanish tax corresponding to this income.

Numerical example: if France has taken 15% at source on your dividends and the corresponding Spanish IRPF is 19 %, Spain will grant you a credit of 15 % — you only pay the difference of 4% to the Hacienda. If the French rate is equal to or higher than the Spanish rate, the credit covers the whole thing: you do not have to pay anything extra in Spain.

2. The exemption method with progressiveness

Applicable in particular to real estate income from French sources or French civil service retirement pensions. This income is not taxable only in France. However, Spain requires you to declare them: they will not be taxed directly, but they will be taken into account to determine the tax rate applicable to your other Spanish income (this is called the effective rate).

Concretely: a French rent of €15,000/year will not be taxed in Spain, but it may increase your tax rate by 24 % à 27 % on your Spanish income. The impact varies greatly depending on your total income level.

Rates withheld at source on cross-border income

The convention sets maximum withholding tax rates for flows between the two countries:

• Dividends : withholding limited to 15 % (5% if the beneficiary company holds more than 25% of the capital)
• Interests : withholding limited to 10 %
• Royalties (licences, patents): retention limited to 5 %

These rates can only be levied by the source State; if the internal rate of that State is lower, the internal rate applies.

The Modelo 720: reporting obligation in Spain

If you reside in Spain and hold property or bank accounts in France worth more than 50 000 €, you are required to declare them via the Modelo 720. This informative declaration (not taxable in itself) lists your bank accounts, securities and real estate held abroad. Failure to comply with this obligation historically resulted in very high fines – the CJEU deemed them disproportionate in 2022, but the reporting obligation remains in force.

The Beckham regime: a tax alternative for impatriates

For people who settle in Spain after having resided abroad for at least 5 years, the impatriate regime (Beckham law) constitutes a radically different alternative to the classic convention. Rather than applying the progressive IRPF scale (which goes up to 47 %), the Beckham regime caps taxation at a flat rate of 24% on income from Spanish sources up to €600,000, for 6 years.

This regime is completely distinct from the Franco-Spanish double taxation agreement: income from French sources remains taxable in France, income from Spanish sources is taxed at 24% under Beckham. The combination of the two mechanisms — convention + Beckham — can generate significant optimization for managers and executives moving to Barcelona or Madrid.

Practical note on forms

On the French side, to declare income from foreign sources while avoiding double taxation, you must use the form 2047 in addition to the classic 2042 declaration. On the Spanish side, the annual IRPF declaration (form 100) takes into account the tax credits of the convention. If you manage a cross-border business from Barcelona or San Sebastián, our team of Fractional CFOs in Barcelona regularly supports managers in structuring this type of situation.

These tax credit and exemption mechanisms take on their full meaning as soon as a French company opens a subsidiary in Spain: each intra-group flow (management fees, dividends, loans) is affected by the agreement. Manage a Spanish subsidiary from France then calls for rigorous monitoring of these cross-border flows to avoid adjustments on both sides of the border.
