France-Spain tax treaty: how to avoid double taxation

The tax treaty between France and Spain, signed on 10 October 1995, determines which of the two states may tax each category of income, and removes double taxation through two mechanisms: the tax credit and exemption with progression. It covers income tax, corporation tax and wealth tax.

When you earn income in one country (the source state) but live in the other (the state of residence), the risk of being taxed twice on the same income is real. Here is what the treaty provides, category by category:

The principle of tax residence

Under the treaty, it is your tax residence that determines which state has the right to tax your worldwide income. If you are tax resident in Spain, you must declare all your income (French and Spanish) to the Hacienda. Spain then gives you a mechanism to offset the tax already paid in France.

Spanish tax residence rests on three alternative tests: presence in the country for more than 183 days in the calendar year, centre of economic interests in Spain (main place of work or business), or centre of vital interests (family, main home). Any one criterion is enough to be treated as a Spanish tax resident.

The two methods for removing double taxation

Depending on the type of income, the France-Spain treaty provides two distinct methods:

1. The credit method (tax credit)

This is the most common method, used in particular for dividends, interest and royalties. Spain calculates the tax on your total income, then deducts what you have already paid in France, up to the amount of Spanish tax due on that income.

Worked example: if France has withheld 15% at source on your dividends and the corresponding Spanish IRPF is 19%, Spain will grant you a credit of 15% — you pay only the 4% difference to the Hacienda. If the French rate is equal to or higher than the Spanish rate, the credit covers everything: there is nothing more to pay in Spain.

2. The exemption-with-progression method

This applies in particular to French rental income and French civil service pensions. Such income is taxable only in France. Spain still requires you to declare it, however: it is not taxed directly, but it is taken into account when setting the rate applied to your other Spanish income (the so-called effective rate).

In practice: French rental income of €15,000/year is not taxed in Spain, but it can push up your tax rate by 24% to 27% on your Spanish income. The impact varies widely with your total income.

Withholding rates on cross-border income

The treaty caps withholding tax rates on flows between the two countries:

• Dividends: withholding capped at 15% (5% if the recipient company holds more than 25% of the share capital)
• Interests: withholding capped at 10%
• Royalties (licences, patents): withholding capped at 5%

Only the source state may levy these rates; if its domestic rate is lower, the domestic rate applies.

Modelo 720: the filing obligation in Spain

If you live in Spain and hold property or bank accounts in France worth more than €50,000, you must declare them on the Modelo 720. This informational return (not itself a tax) lists the bank accounts, securities and property you hold abroad. Historically, failing to file carried very heavy fines — the CJEU ruled them disproportionate in 2022, but the filing obligation remains in force.

The Beckham regime: a tax alternative for impatriates

For people moving to Spain after at least 5 years living abroad, the impatriate regime (Beckham law) is a radically different alternative to the standard treaty route. Rather than applying the progressive IRPF bands (which climb to 47%), the Beckham regime caps taxation at a flat rate of 24% on Spanish-source income up to €600,000, for 6 years.

This regime is entirely separate from the France-Spain double taxation treaty: French-source income remains taxable in France, while Spanish-source income is taxed at 24% under Beckham. Used together — treaty plus Beckham — the two can offer significant tax optimisation for directors and executives relocating to Barcelona or Madrid.

A practical note on forms

On the French side, to declare foreign-source income without being taxed twice, you use form 2047 alongside the standard 2042 return. On the Spanish side, the annual IRPF return (form 100) applies the treaty's tax credits. If you run a cross-border business from Barcelona or San Sebastián, our team of Fractional CFOs in Barcelona regularly helps executives structure this kind of situation.

These credit and exemption mechanisms come into their own as soon as a French company opens a Spanish subsidiary: every intra-group flow (management fees, dividends, loans) falls within the treaty. Running a Spanish subsidiary from France then calls for rigorous tracking of these cross-border flows to avoid reassessments on either side of the border.
