How French Stock Options Work
A stock option plan grants selected employees and/or corporate officers the right to subscribe to a capital increase (options de souscription) or to purchase existing shares (options d'achat) at a price fixed at attribution, for a limited period. The exercise price cannot in principle be modified once set. If the share price rises above the exercise price during the option's life, the holder may acquire shares at the lower fixed price and either sell immediately to realise a profit or hold for further appreciation.
The plan is purely voluntary. In listed companies, the board's power to attribute options to executive officers (dirigeants) is subject to a condition: the company must either distribute options or free shares to all employees and at least 90% of French-subsidiary employees, or implement or improve a participation or intéressement scheme (C. com. Art. L 22-10-58). Where options are granted to executive officers, the board must additionally either prohibit them from exercising the options before leaving their functions or require them to hold resulting shares in registered form until their functions end.
Three key dates
- The attribution date: when the board grants the options — the reference point for most fiscal consequences, including which regime applies (pre- or post-28 September 2012) and the benchmark share price used to measure the maximum permitted discount.
- The legal availability date: the earliest date on which the holder may exercise the option, as set in the plan rules. Plan rules often include a vesting schedule or a continued employment condition.
- The fiscal availability date: a concept applicable only to options attributed before 28 September 2012 — the date from which the holder could sell the resulting shares without losing access to the preferential tax rates. For options attributed from 28 September 2012 onwards, this concept no longer exists.
The continued employment condition (clause de présence)
Many plans include a clause requiring the beneficiary to remain employed at the date of exercise. A beneficiary who leaves before exercising loses the right to do so, even if the exercise deadline has not yet passed — provided the clause was brought to their knowledge (Cass. com. 23-3-2010). Dismissal without genuine and serious cause does not revive the right to exercise but entitles the employee to damages for loss of chance — capped at the value of the chance lost and taxed as salary income. A forfeiture clause triggered specifically by gross-misconduct dismissal is treated as a prohibited financial sanction and is deemed non-written, so the employee retains the right to exercise in that circumstance.
The Three Components of the Financial Gain
1 — The discount (rabais)
The exercise price may be set below the market price at attribution. The maximum permitted discount is 20% of the average quoted price over the 20 trading sessions preceding the attribution date, or of the average purchase price for buy-back options. Only the excess beyond 5% of the share's value at attribution (rabais excédentaire) — 10% for options attributed before 1 July 1993 — is taxable. This excess is taxed as salary income in the year of exercise, plus CSG at 9.2% and CRDS at 0.5% as employment income, withheld at source by the employer on the pay slip following exercise. Social security contributions also apply from 1 January 1995. The already-taxed fraction reduces the acquisition gain base at eventual disposal.
Average price over 20 sessions before attribution: €30. Maximum permitted discount (20%): €6. Exercise price: €24. Actual discount: €6 (= 20% of €30). 5% threshold: €1.50. Taxable excess discount: €4.50 per share — declared as salary income in the year of exercise, subject to CSG/CRDS and social security contributions from 1 January 1995.
If the holder then sells at €45, the acquisition gain for tax purposes is: €45 − €24 − €4.50 = €16.50, not €21.
2 — The acquisition gain (avantage tiré de la levée de l'option)
The acquisition gain is the difference between the share's real value at the date of exercise and the exercise price (net of any already-taxed excess discount). It represents the benefit the holder receives from exercising the option: the right to buy a share worth €33 for €24 creates an acquisition gain of €9 per share. This is the central element of the stock option fiscal regime — and the one whose tax treatment changed most dramatically in 2012.
3 — The disposal gain (plus-value de cession)
The disposal gain is the further appreciation between the share's value at the date of exercise and the price achieved on eventual sale. If the share was worth €33 at exercise and is sold at €45, the disposal gain is €12. If sold at €31, there is no disposal gain — but the acquisition gain is partially clawed back by the fall.
Options Attributed from 28 September 2012: The Current Regime
For all options attributed from 28 September 2012, the acquisition gain is taxed as salary income in the year of disposal of the shares — not in the year of exercise (CGI Art. 80 bis II bis). The taxable event is the disposal (whether by sale, gift, bearer conversion, or transfer into a securities lending arrangement). There is no minimum holding period, no fiscal availability date, and no preferential rate.
Income tax on the acquisition gain
The acquisition gain, reduced if applicable by the already-taxed excess discount, is added to the holder's other income and taxed under the progressive income tax scale in the category of employment income (traitements et salaires). The 10% professional expense deduction does not apply. No income-splitting quotient mechanism may be invoked. Tax is due for the year in which the disposal occurs.
Social charges on the acquisition gain
The acquisition gain is subject to CSG at 9.2% and CRDS at 0.5% as employment income — collected in practice in the year following the disposal, when filing the income return. No other social security contributions apply to the acquisition gain itself. For all options attributed from 16 October 2007, an additional specific employee contribution of 10% applies to the net acquisition gain (reduced by any disposal loss on the same shares), payable at the date of disposal (CSS Art. L 137-14).
The capital gain on disposal
The capital gain (the difference between the sale price and the share's value at exercise) is treated as an ordinary securities capital gain and taxed at PFU 12.8% or, on global election, under the progressive scale, plus 17.2% social charges. Duration abatements are available only for shares acquired before 1 January 2018 under CGI Art. 150-0 D, calculated from the date of exercise. The €500,000 specific abatement for retiring SME directors (CGI Art. 150-0 D ter) is available for the capital gain. Abatements on the capital gain do not reduce the basis for social charges.
Disposal loss offsetting the acquisition gain
If the shares are sold for less than their value at the date of exercise, the resulting disposal loss is deductible from the acquisition gain up to the amount of that gain (CGI Art. 80 bis IV al. 2). Any surplus disposal loss not absorbed may be offset against other securities capital gains in the same year or carried forward over the following ten years under ordinary capital gains rules.
1,000 options attributed 1 March 2013 at an exercise price of €50. Exercised 1 April 2022 when the market price is €75. All 1,000 shares sold 15 September 2024 at €10 each.
Disposal: sale price €10,000 − value at exercise €75,000 = disposal loss of −€65,000
Net acquisition gain after offset: €25,000 − €65,000 = €0 — fully absorbed
Residual disposal loss to carry forward: −€40,000 (€65,000 − €25,000)
This €40,000 is offset against other securities capital gains in 2024 or over the next 10 years
Options Attributed Before 28 September 2012: The Old Regime
Options attributed before 28 September 2012 remain subject to the regime in force at their attribution date. These are held by many employees and executives in long-running plans and may not yet have been exercised or sold, making the legacy rules still practically relevant.
Options attributed before 20 September 1995
The acquisition gain is taxed as an ordinary capital gain on securities at PFU 12.8% or, on global election, at the progressive scale, plus 17.2% social charges. No specific rate applies.
Options attributed 20 September 1995 to 26 April 2000
The acquisition gain is taxed at a specific rate of 30% for disposals made after meeting the then-applicable fiscal availability conditions, or on global option as salary income (without the quotient mechanism), plus 17.2% social charges.
Options attributed 27 April 2000 to 27 September 2012
The most complex group. The preferential rates apply only if the shares are sold at least four years after the attribution date (the fiscal availability period). The rate depends on whether the holder has also observed a further two-year holding period after exercise (the période de portage) (CGI former Art. 200 A, 6):
- Without the two-year portage period: 30% on the portion of the acquisition gain not exceeding €152,500; 41% on the surplus. Combined with 17.2% social charges: global rates of 47.2% and 58.2%.
- With the two-year portage period: 18% on the portion not exceeding €152,500; 30% on the surplus. Combined with 17.2% social charges: global rates of 35.2% and 47.2%.
On global election, the acquisition gain may alternatively be taxed as salary income (without the quotient mechanism), plus 17.2% social charges. Where a share exchange (OPA, merger, demerger, share split or grouping) occurs during the two-year portage period, the exchange is treated as an opération intercalaire — it does not restart the portage clock and does not forfeit the right to the lower rate.
Disposal loss for pre-2012 plans
The disposal-loss offset rule works the same way as for post-2012 options: a disposal loss reduces the acquisition gain up to its amount, with any residual deductible against other capital gains under ordinary rules. For options attributed before 20 June 2007, ordinary capital gains losses from other securities may additionally be offset against the acquisition gain. For options attributed from 20 June 2007, this cross-offsetting is not available because the acquisition gain is taxed under an autonomous regime (CGI Art. 200 A, 6) outside the ordinary securities capital gains framework.
Summary Table by Attribution Date
| Attribution period | Acquisition gain: income tax | Acquisition gain: social charges | Capital gain on disposal |
|---|---|---|---|
| Before 20 September 1995 | Capital gains regime (PFU 12.8% or progressive scale) | 17.2% PS (revenue from assets) | Capital gains regime (PFU 12.8% or progressive scale) + 17.2% PS |
| 20 September 1995 – 26 April 2000 | 30% flat rate or salary (no quotient); after fiscal availability | 17.2% PS (revenue from assets) | Capital gains regime + 17.2% PS |
| 27 April 2000 – 19 June 2007 | 18% or 30% (with portage); 30% or 41% (without portage); or salary on election. Fiscal availability: 4 years from attribution | 17.2% PS (revenue from assets) | Capital gains + duration abatements (if acquired before 1 January 2018) + 17.2% PS |
| 20 June 2007 – 27 September 2012 | Same preferential rates as above. Ordinary capital gains losses cannot offset this gain | 17.2% PS (revenue from assets) + 10% specific employee contribution on net gain | Capital gains + duration abatements (if pre-2018) + 17.2% PS |
| From 28 September 2012 | Salary income (progressive scale; no quotient; no 10% deduction); taxed in year of disposal | 9.2% CSG + 0.5% CRDS as employment income; 10% specific employee contribution on net gain | PFU 12.8% or progressive scale + 17.2% PS (no abatements for shares acquired from 1 January 2018) |
Indemnities for Non-Exercise: Salary Income
When options are not exercised — for example, because a public tender offer is followed by a mandatory squeeze-out — the company often pays an indemnity to option-holders in exchange for their renunciation. The Conseil d'État has consistently held that such indemnities, and any advantage received in exchange for deferring exercise, are taxable as salary income (traitements et salaires) rather than as capital gains, because they compensate for the non-exercise of a right granted in consideration of the beneficiary's employee status (CE 23-7-2010; CE 1-10-2013; CE 5-11-2014). This rule applies to both employees and corporate officers, and to options attributed both before and after 28 September 2012.
Identifying Which Shares Were Sold
Where the holder's portfolio contains shares in the same company acquired through multiple routes — market purchases, option exercises from different plans — and some shares are sold without being individually identifiable, the sold shares are treated as drawn from each category in proportion to that category's share of the total portfolio at the date of sale. This proportionate attribution is applied to compute the acquisition gain and the capital gain for each tranche. Holders wishing to optimise taxation across different plans should consider holding shares from each exercise in separate designated accounts at different custodians, allowing them to choose which tranche is being sold for each disposal.
Key Planning Observations
Early exercise when the share price is low (pre-2012 options)
For plans still subject to the old proportional rates, exercising the option when the share price is near or below the expected long-term level minimises the acquisition gain (taxed at the higher preferential rates) and maximises the capital gain (taxed at the lower PFU rate of 12.8% + 17.2% social charges = 30% total). The strategy also starts the two-year portage clock running earlier, potentially accelerating access to the reduced rates. The practical costs are the financing charge for the exercise price and the capital risk if the share subsequently falls below the exercise price.
Round-trip when the share price has fallen since exercise (pre-2012 options)
Where shares acquired through option exercise have fallen in price since exercise, the holder may sell and repurchase (aller-retour) to crystallise the acquisition gain at the current (lower) price — triggering the preferential rate on a smaller amount — while reclassifying the expected future appreciation as a capital gain taxable at PFU 30% total. Since 1 January 2020, this structure carries a theoretical abuse-of-law risk under LPF Art. L 64 A; to mitigate this, the round-trip should be accompanied by genuine portfolio diversification rather than an immediate like-for-like repurchase of the same quantity of shares.

Book a ConsultationThis article covers the income tax and social charges treatment of stock options (options de souscription ou d'achat d'actions) attributed to French tax-resident individuals from 1 January 1990. Free share plans (actions gratuites) and BSPCE (bons de souscription de parts de créateur d'entreprise) follow different rules not covered here. The interaction between the pre-2012 portage rules and share exchange operations in the context of M&A transactions involves additional provisions not fully addressed here. The rules described apply to individuals domiciled in France for tax purposes; cross-border situations involve specific allocation rules outside the scope of this article.

Listed company board conditions for attributing options to executive officers: must distribute options or free shares to all employees (at least 90% of French-subsidiary employees), or implement/improve a participation or intéressement scheme.
Excess discount (rabais excédentaire): the fraction of the discount above 5% of the share’s value at attribution (10% for pre-1 July 1993 options) is taxable as salary income in the year of exercise, subject to the progressive scale and social charges; the already-taxed excess reduces the acquisition gain base at disposal; employer withholds at source on the pay slip following exercise.
Post-28 September 2012 options: acquisition gain (avantage tiré de la levée de l’option) is taxed as salary income (traitements et salaires) in the year of disposal of the shares; no minimum holding period; no fiscal availability date; no preferential rate; no 10% professional expense deduction; no quotient mechanism.
Disposal loss offset: if shares are sold for less than their value at the date of exercise, the resulting disposal loss is deductible from the acquisition gain up to the amount of that gain; any surplus may be offset against other securities capital gains in the same year or carried forward over 10 years.
Pre-28 September 2012 options (27 April 2000–27 September 2012): preferential rates of 18%/30% (with two-year portage period after exercise) or 30%/41% (without portage), applicable to options held for at least four years from the attribution date (fiscal availability period). On global election: salary income without the quotient mechanism.
Duration abatements for capital gains on securities, calculated from the date of exercise for stock option shares: available only for shares acquired before 1 January 2018; apply to income tax base only, not social charges base; not applicable to the acquisition gain component for any attribution period.
€500,000 fixed abatement on the capital gain component for retiring SME directors (dirigeants de PME partant en retraite): available for the disposal gain on stock option shares; does not apply to the acquisition gain for any attribution period.
10% specific employee contribution on the net acquisition gain (reduced by any disposal loss on the same shares): applies to all options attributed from 16 October 2007, payable by the employee at the date of disposal, collected by the tax authorities as if income tax; applies both to old preferential rate plans (2007–2012 attribution window) and new salary-income regime (from 28 September 2012); not assessed on the capital gain component.
Indemnities for non-exercise of stock options (due to public tender offer, mandatory squeeze-out, or deferral agreement) are taxable as salary income (traitements et salaires) for both employees and corporate officers, regardless of the option’s attribution date, because they compensate for the non-exercise of a right granted in consideration of employee status.
Social Charges: The Complete Picture
Excess discount (rabais excédentaire): CSG and CRDS apply as employment income from exercise from 1 January 1995. Social security contributions and aligned contributions (Agirc-Arrco from 1 January 1996) also apply, in the same way as salary, withheld at source by the employer on the pay slip following exercise.
Acquisition gain: CSG and CRDS apply as revenue from assets (revenus du patrimoine) in the year of disposal, at 17.2%. Post-2012 options: assessed as employment income at 9.2% + 0.5% instead. Social security contributions do not apply to the acquisition gain for properly compliant plans. Where a company fails to meet its mandatory URSSAF filing obligations for post-2012 plans, the acquisition gain becomes subject to social security contributions — but in that case the employer bears the entirety of those contributions, including the employee's share.
The 10% specific employee contribution (CSS Art. L 137-14): For options attributed from 16 October 2007, a dedicated 10% contribution is due by the employee on the net acquisition gain (reduced by any disposal loss on the same shares), payable at the date of disposal, collected by the tax authorities. It applies whether the plan falls under the old preferential rates (2007–2012 attribution window) or the new salary-income regime (from 28 September 2012). Not assessed on the capital gain component.
Capital gain: Social charges at 17.2% apply as revenue from assets, assessed on the full capital gain without abatement, regardless of any duration abatement that may reduce the income tax base.
