Stock options in France: 2026 tax rules and traps to avoid

Stock options give the holder the right to buy shares in their company at a price fixed in advance (exercise price), generally below their market value at the time of exercise. The resulting gain is taxable — but under rules that depend on the date the plan was awarded.

The three levels of taxation

The tax treatment of stock options breaks down into three stages, each generating a separate tax charge.

1. The excess discount (at the time of award)

Two thresholds coexist for listed companies:

• Legal threshold (French Commercial Code art. L225-177): if the exercise price is below 80% of the average price over the last 20 trading sessions, the discount is excessive under company law.
• Tax threshold (CGI art. 80 bis II): fiscally, the threshold applied is 95% of the same average price. The portion of the discount exceeding this fiscal threshold is taxed as ordinary salary at the time of award.

Accordingly, an exercise price set at 82% of the average price does not trigger a legal excess discount, but does trigger a fiscally taxable excess discount (the spread between 82% and 95%). In practice, most plans are structured to stay above both thresholds.

2. The exercise gain (when options are exercised)

This is the main benefit: the difference between the value of shares on the exercise date and the exercise price. This gain is taxable in the year of exercise.

Its tax regime depends on the date of award:

Plans awarded before 28 September 2012:
The exercise gain is taxed at a flat rate depending on whether the additional holding period has been observed (source: impots.gouv.fr, 08/04/2026):

Without additional holding period (4-year unavailability period observed):
- 30% for the fraction ≤ €152,500
- 41% for the fraction > €152,500

With additional 2-year holding period (total period of 6 years from award):
- 18% for the fraction ≤ €152,500
- 30% for the fraction > €152,500

In all cases, an option for taxation under the progressive employment income scale is available. If the deadlines are not observed, the gain is reclassified as salary.

Plans awarded from 28 September 2012:
The exercise gain is taxed as ordinary salary under the progressive scale, without a flat rate. It is also subject to employee and employer social security contributions. The tax advantage of post-2012 plans is therefore significantly reduced.

3. The capital gain on disposal (when shares are sold)

When you sell the shares acquired through exercise, the capital gain equals the sale price less the value of the shares on the exercise date (your tax cost basis). It is subject to the standard securities capital gains regime: flat tax at 31.4% (12.8% income tax + 18.6% social levies) or progressive scale on election.

Qualifying vs non-qualifying plans

A plan is qualifying if it meets the conditions of CGI article 163 bis C: joint stock company, awards to employees and officers under the statutory conditions, exercise price not below 80% of the average price, holding periods observed.

A non-qualifying plan (or "phantom options", options on unlisted securities not meeting the conditions) generates a gain taxed as a benefit in kind or salary, without the specific regimes.

Social security contributions: an often underestimated issue

For post-2012 plans, the exercise gain is subject to social security contributions (both employee and employer), not merely social levies. The difference is significant: the total contribution rate can exceed 40% on the combined employee and employer side.

This change has made free share awards (AGA) structurally more advantageous than stock options for recent plans — hence their rise in popularity.

Exercise strategy

The timing of when you exercise your options has a direct impact on your tax bill:

• Exercise in a year of low income: reduces the impact of the progressive scale if the exercise gain is treated as salary
• Staggered exercise over several years: smooths the tax charge
• Holding after exercise: allows deferral of the capital gain on disposal, but exposes you to the risk of a price decline

Management packages: a related regime to be aware of

Since 15 February 2025, a specific regime applies to gains realised by employees or officers on equity instruments under "management packages" — BSAs, convertible bonds, preference shares, etc. (LF 2025, art. 93; CGI art. 163 bis H).

The gain is taxed as a securities capital gain up to a threshold linked to the company's financial performance during the holding period. The fraction exceeding this threshold is taxed as ordinary salary. A specific 10% employee contribution applies to the salary fraction (CSS art. L137-42).

This regime is distinct from standard stock options and BSPCE. If you hold instruments of this type, the tax treatment depends on the date of disposal and the precise nature of the instrument.

Filing

• The exercise gain is in principle declared by the employer and pre-filled, but verify the box: old plans and recent plans are not declared in the same way
• Qualifying old plans: form 2042 C
• Post-2012 plans: form 2042, salary boxes
• Capital gain on disposal: form 2042, securities capital gains boxes

Pre-2012, post-2012, management packages: each situation has its own filing treatment

Depending on your plan date, the applicable regime and forms differ. A treatment error can result in taxation at the wrong rate — with significant differences on large amounts.

Fidencia.tax identifies the date and nature of your plan and guides you through your return — including for management packages under the new regime since 15.02.2025.
