Prop firm payouts and tax in France

No official French position on prop-firm payouts. The residual category under art. 92 CGI is bénéfices non commerciaux (BNC), which covers profits not falling in another category. That is the most likely home for a performance/service fee paid by a foreign firm. Professional (habitual) vs non-professional BNC changes the boxes and the social-contribution treatment.

Usually taxed as: business incomeNo specific ruling — general rules appliedTax year: calendar year (1 Jan – 31 Dec)

The France tax office has not ruled on prop-firm payouts specifically. The treatment below applies the general rules for this kind of income. Basis: BOFiP BOI-BNC-CHAMP-10-10-20 (art. 92 CGI): BNC includes income from lucrative occupations/sources of profit not belonging to another category of income; the BOFiP page lists 'opérations de bourse' as a separate sub-category. There is no ruling specific to prop firms.

Registration, costs and currency

Registering
Micro-entrepreneur: services threshold €77,700 for 2025 income and €83,600 from 2026 income, based on 2024 or 2025 turnover, with a 34% flat allowance (minimum €305) (service-public F23267). A habitual professional activity needs a business registration through the guichet unique, which brings URSSAF contributions. That registration step is not verified from an official page here. Non-professional BNC needs no business registration. Source: entreprendre.service-public.gouv.fr
Challenge fees and other costs
Deductible: likely. Under micro-BNC no actual expenses are deductible because the 34% flat allowance replaces them. Under déclaration contrôlée (2035), costs incurred for the activity are deductible under the general BNC rules. No specific guidance on challenge fees.
Converting to EUR
No official BNC-specific rule found. BOFiP BOI-BIC-BASE-20-20 §180, which is for BIC/IS, uses the Banque de France rate closest to year-end for receivables. For cash-basis BNC the commonly applied practice is the rate on the day of receipt, but this is UNVERIFIED.

What to watch out for

  • Social contributions depend on status: URSSAF micro-entrepreneur rates, SSI under the réel regime, or 17.2% prélèvements sociaux on non-professional BNC. None of these is modelled.
  • Do not claim the professional vs non-professional split; it depends on facts.
  • The 2042-C-PRO box numbers come from the 2026 campaign (2025 income) brochure; they can change yearly.
  • The versement libératoire option is not modelled.
