Selling pre-IPO startup shares in France: BSPCE, approval and tax

France leans on BSPCE and other tax-advantaged instruments. Here’s what you hold, what the pacte d’associés controls, and how the flat tax (and the BSPCE 3-year rule) works.

Quick answer. For BSPCE you exercise first, then sell. Capital gains are generally taxed under the flat tax (PFU, 31.4% from 2026); BSPCE has its own treatment, more favourable with 3+ years' seniority. The pacte d'associés usually requires agrément and respects a droit de préemption.

France has some of Europe’s most developed startup-equity instruments — and the one you hold, especially BSPCE, changes both how you sell and how you’re taxed.

What do you hold? BSPCE, options, or free shares

What controls a transfer

In an SAS, the by-laws (statuts) and the pacte d’associés usually contain an approval clause (agrément) and a pre-emption right (droit de préemption). As elsewhere, you typically offer internally or seek approval first, then complete with your buyer.

Tax when you sell (directional)

Capital gains are generally taxed under the flat tax (PFU) at 31.4% for gains realised from 2026 (12.8% income tax + 18.6% social levies; it was 30% through 2025). For BSPCE, a 2025 reform changed the treatment: broadly, the built-in gain at exercise is taxed as employment-type income (a favourable flat rate with 3+ years’ seniority, higher below that), while any further gain up to the sale is an ordinary capital gain. The details are specific and rates change — confirm with a French adviser. Source ↗

The French gotcha: BSPCE seniority (the 3-year mark) materially affects your tax, and the pacte d’associés usually requires agrément and respects a droit de préemption. Check both your BSPCE terms and the pacte before you sell.

Questions people ask

Can I sell my startup shares in France?
Often yes. In an SAS (the usual French startup form), shares transfer relatively freely, subject to the by-laws (statuts) and the shareholders' agreement (pacte d'associés), which usually include an approval clause (agrément) and a pre-emption right (droit de préemption). BSPCE and options are exercised into shares before selling.
How is a startup share sale taxed in France?
Capital gains are generally taxed under the flat tax (PFU) at 31.4% for gains realised from 2026 — 12.8% income tax plus 18.6% social levies (it was 30% through 2025). For BSPCE, a 2025 reform means the gain at exercise is taxed as employment-type income (a favourable flat rate with 3 or more years' seniority, higher below that), while any further gain up to the sale is an ordinary capital gain. Rates change, so confirm with a French tax adviser.
What is BSPCE and how does it affect selling?
BSPCE (Bons de Souscription de Parts de Créateur d'Entreprise) is France's tax-advantaged startup equity instrument. You exercise BSPCE to acquire shares, then sell the shares. The tax on the eventual gain depends on your seniority at the company (a 3-year threshold matters), so your holding period affects your net outcome — check your BSPCE terms before selling.
