The France-Spain tax treaty: residence, presence and people.
Between two EU states the directives handle the money. The treaty handles the harder questions — who is resident where, when presence becomes taxable, and which country taxes a person who works in both.
France and Spain have a long-standing double taxation convention, modified by the OECD multilateral instrument to which both states are parties. For a French group with a Spanish subsidiary, most day-to-day intra-group flows are governed by the EU directives rather than by that convention. What the treaty actually decides is people and presence — and given a shared land border, those questions arise constantly.
What the treaty decides, and what it does not.
| Question | Instrument | Note |
|---|---|---|
| Dividends between associated companies | Parent-Subsidiary Directive | Potentially 0%, subject to conditions |
| Interest and royalties between associated companies | Interest and Royalties Directive | Potentially 0%, beneficial ownership required |
| Dividends to individuals | Treaty | Reduced rate against Spanish domestic withholding |
| Corporate and personal residence | Treaty | Tie-breaker where both states claim |
| Permanent establishment | Treaty, as modified by MLI | The definition that matters for cross-border sales |
| Employment income | Treaty | Generally taxed where the work is done, with exceptions |
| Directors' fees | Treaty, separate article | Often a different rule from salary |
| Social security | EU coordination rules | Not the treaty. Can land in a different state |
Income tax and social security are decided by different instruments.
A French employee working substantially in Spain may be taxable on that employment income in Spain under the treaty while remaining in the French social security system under EU coordination rules, or the reverse. Getting one right tells you nothing about the other, and each requires its own documentation.
Residence: the tie-breaker.
Both countries can claim a person as resident under their own domestic rules — France on the basis of home, main activity or economic interests, Spain on more than 183 days or the centre of economic interests. When both claim, the treaty applies a sequence.
For a founder or executive splitting time between the two countries, the practical lesson is that day-counting alone does not decide the question. Where the family lives, where the assets are and where the economic centre sits generally matter more — and they are harder to change than a calendar.
Cross-border and posted workers.
The France-Spain border produces a category of worker that more distant country pairs rarely generate: people who genuinely work in both countries in the same month, sometimes the same week.
Staff crossing informally for years
Technicians on Spanish client sites, sales staff covering Catalonia from Toulouse, nobody counting days, no posting documentation, and salary costs recharged inconsistently or not at all.
Days tracked, documents held, costs allocated
A record of where work is performed, correct posting certificates, cost recharges that match the reality, and a deliberate decision about which entity employs whom.
Claiming relief in practice.
- A valid tax residence certificate from the French authorities, current for the relevant period
- Evidence of beneficial ownership where a reduced rate or exemption is claimed
- Holding percentage and period documented, where directive relief is relied on
- Arm's-length pricing and documentation for any intercompany charge
- Related-party reporting filed, which is a separate Spanish obligation
- Consistency between what the French accounts show and what the Spanish filings say
Get the residence certificate before the payment, not after it.
Where relief is claimed without supporting documentation in place, Spanish domestic withholding may be applied and recovered only through a refund procedure — which works, but slowly, and ties up cash in the meantime.
- Convention fiscale
- The double taxation convention, in French. Convenio de doble imposicion in Spanish.
- Etablissement stable
- Permanent establishment. Establecimiento permanente in Spanish.
- Attestation de residence fiscale
- Tax residence certificate — the document Spain requires before applying treaty or directive relief.
- Travailleur detache
- Posted worker, with its own social security documentation requirements under EU coordination rules.
- Centre des interets vitaux
- Centre of vital interests — usually the decisive residence tie-breaker.
- MLI
- The multilateral instrument, which modifies the bilateral convention without renegotiating it.
A Spanish entity settles most of them by construction.
Incorporation, tax activation, employer registration and related-party documentation — so residence, employment and presence are decided deliberately rather than argued about afterwards.
