France long-term losses on equity participations 2026: Copé niche, corporate tax (IS) and symmetric treatment
France corporate income tax (IS) 2026 regime for long-term capital losses on equity participations: Copé niche (CGI Art. 219 I a quinquies), 12% QPFC recharge, non-deductible losses, 10-year carryforward, symmetric treatment, intra-group disposals and practical watchpoints.

The "Copé niche" — the colloquial name for the long-term capital gains exemption on equity participations (titres de participation) under CGI Article 219 I a quinquies — is one of the most structurally significant tax benefits available to French corporate groups. A disposal gain may be subject to an effective IS rate of just 3% rather than the standard 25%. The flip side is equally significant: by deliberate symmetry, long-term capital losses on those same shares are not deductible from ordinary taxable income. They remain trapped until they can be offset against future long-term gains, within a ten-year window.
For holding companies managing mixed portfolios of winning and losing participations, this asymmetry — visible on gains, invisible on losses — generates material unexpected tax costs that are frequently discovered late, during the preparation of the annual corporate tax return.
In brief. Long-term gains on equity participations held ≥ 2 years are 88% exempt from IS; only a 12% recharge (QPFC) is taxed at 25%, yielding a 3% effective rate. Long-term losses on the same shares are not deductible against ordinary income — they offset only long-term gains of the same nature, within 10 years.
1. What qualifies as an equity participation (titre de participation) under French tax law?#
The tax qualification determines which regime applies. It does not automatically follow accounting classification, although the two frequently coincide.
Automatically qualified (CGI Art. 39 quaterdecies I-1 a):
- Shares representing at least 5% of the capital of the issuing company (legal presumption).
- Shares qualifying for the parent-subsidiary regime (CGI Art. 145).
- Shares received in exchange for a partial business contribution (apport partiel d'actif) under the favourable rollover regime.
- Shares accounting-classified as participations under French GAAP (PCG Art. 211-3) and recorded in account 261.
Excluded from the regime:
| Category | Applicable tax regime |
|---|---|
| Short-term investment securities | Standard rate 25% |
| UCITS, FCP, SICAV (except specific carve-outs) | Standard rate 25% |
| Unlisted real-estate holding companies (SPI) held non-operationally | Standard rate 25% |
| Shares issued by an ETNC entity (CGI Art. 238-0 A) | Standard rate 25%, no Copé niche |
| Shares held for documented speculative purposes | Standard rate 25% |
Practice note. Qualification documentation must be contemporaneous with acquisition: board resolution, investment memorandum, initial accounting entry in account 261. A retroactive reclassification — even in good faith — will be very difficult to sustain under a DGFiP audit. This is the most common procedural weakness in participation tax files.
2. The Copé niche mechanism for long-term gains#
Effective IS calculation#
CGI Article 219 I a quinquies exempts 88% of the net long-term gain. A mandatory recharge for fees and charges (QPFC) of 12% is taxed at the standard 25% rate.
| Step | Amount |
|---|---|
| Gross long-term gain on disposal | €1,000,000 |
| Taxable QPFC recharge (12%) | €120,000 |
| IS on QPFC (25%) | €30,000 |
| Effective tax rate | 3% |
Minimum holding condition#
The two-year holding period runs from the balance-sheet entry date (accounting recognition date), not from the legal acquisition date or the date conditions precedent are fulfilled.
Critical QPFC calculation rule#
The 12% recharge is calculated on the gross gain of each disposal, before any offset against long-term losses realised in the same year. Even if the year's net long-term result is zero after compensation, the gross gains of individual disposals still generate a QPFC charge. This is a point regularly missed in tax planning models.
3. The asymmetric treatment of long-term losses#
Non-deductibility principle#
Net long-term losses on equity participations held ≥ 2 years:
- are not deductible from standard-rate (25%) taxable income,
- are imputable only on net long-term gains of the year of realisation or of the 10 following financial years (CGI Art. 39 quaterdecies I),
- if not offset within 10 years, the long-term loss is permanently lost for tax purposes.
Comparative treatment table#
| Nature | IS treatment | Effective rate | Offset mechanism |
|---|---|---|---|
| Long-term gain — equity participation (≥ 2 years) | 88% exempt, QPFC 12% taxable | 3% | N/A |
| Long-term loss — equity participation (≥ 2 years) | Not deductible at standard rate | 0% IS saving | Against LT gains within 10 years |
| Short-term gain (< 2 years) | Taxable at standard rate | 25% | N/A |
| Short-term loss (< 2 years) | Fully deductible from ordinary income | 25% saving | Immediate |
Our reading. The asymmetry is deliberate: the French state cannot simultaneously exempt gains and allow full deductibility of losses. In practice, a holding company selling a mixed portfolio — winners and losers — in the same year will often pay more IS than the 3% headline rate suggests, because losses do not reduce the QPFC base calculated on gross gains.
4. Worked example — Equity participation disposal at a €200,000 loss#
Scenario. A French IS-taxpayer holding company has held two equity participations for four years. In 2026 it disposes of both.
- Participation A (B2B SaaS): acquired for €500,000, sold for €900,000 → long-term gain: €400,000.
- Participation B (e-commerce): acquired for €1,000,000, sold for €800,000 → long-term loss: −€200,000.
| Disposal | Acquisition cost | Disposal price | Long-term result |
|---|---|---|---|
| Participation A (SaaS, 4 years) | €500,000 | €900,000 | +€400,000 |
| Participation B (e-commerce, 4 years) | €1,000,000 | €800,000 | −€200,000 |
| Net long-term result 2026 | — | — | +€200,000 |
IS calculation:
- Net long-term gain: €200,000 (after offsetting Participation B loss).
- QPFC: calculated on the gross gain of Participation A = €400,000 × 12% = €48,000 taxable.
- IS on QPFC: €48,000 × 25% = €12,000.
What this means in practice. The €200,000 loss on Participation B does offset the net gain, but the QPFC is calculated on the gross gain of €400,000 — not on the net €200,000. The company pays €12,000 IS on an economic net gain of €200,000. Had the loss been deductible at the standard rate, it would have generated an IS saving of €50,000 (€200,000 × 25%). The fiscal cost of the asymmetry in this example is therefore €50,000 of foregone IS saving, plus the QPFC charge of €12,000. Total fiscal drag vs. ordinary regime: €62,000.
5. Participation shares vs. portfolio securities — operational distinctions#
This distinction drives the applicable tax rule and generates restatements across accounting, tax, and group reporting.
| Criterion | Equity participations (titres de participation) | Portfolio securities (titres de portefeuille) |
|---|---|---|
| Ownership threshold | ≥ 5% or parent-subsidiary regime | < 5%, no significant influence |
| Accounting account | 261 or 271 (by influence level) | 503 (short-term investments) |
| Holding period for LT regime | ≥ 2 years | ≥ 2 years (where LT regime available) |
| Gain treatment | Copé niche — 3% effective | Standard rate 25% |
| Loss treatment | Non-deductible, 10-year carryforward | Deductible if held < 2 years |
| Dividend treatment | Parent-subsidiary regime (95% exempt) if conditions met | Taxed at standard rate |
Arbitrage. An investor holding between 3% and 6% of a company faces a genuine choice: increasing to 5% to access the Copé niche on future gains, or staying below 5% to retain full deductibility of a potential loss if the investment deteriorates. This threshold decision must be made at acquisition, not after the fact.
6. Intra-group disposals and long-term loss management#
Tax consolidation (intégration fiscale) regime#
Within a French tax group (CGI Art. 223 A), long-term intra-group gains and losses on equity participations are neutralised at the consolidated level. A loss on an intra-group disposal of a participation generates no deductible charge for the group. When the entity leaves the tax group perimeter, the neutralisations are unwound under CGI Art. 223 F — sometimes with unexpected consequences for previously reported long-term loss carryforwards.
Intra-group disposals outside tax consolidation#
Outside tax consolidation, an intra-group disposal of a participation at a loss creates a non-deductible long-term loss for the selling entity. This mechanism is sometimes used to transfer shares to a group entity better positioned to absorb the loss through future gains — but the operation must have genuine economic substance, otherwise it risks being challenged as an abnormal management act or an abuse of right under LPF Art. L. 64.
What the DGFiP examines. The French tax authority is attentive to intra-group disposals at below-market-value prices followed by a rapid external disposal at a higher price by the acquiring entity. This pattern may be characterised as tax abuse if the primary purpose is fiscal.
7. Articulation with accounting impairment#
A key operational distinction is the difference between accounting impairment and realised fiscal loss.
| Dimension | Accounting (French GAAP / PCG) | Tax (CGI) |
|---|---|---|
| When recognised | Annual impairment test (ANC Reg. 2014-03 Art. 214) | At effective disposal only |
| IS effect | Neutral while shares are held | Long-term gain or loss at disposal |
| Reversal | Possible if value recovers before disposal | Not applicable — one-time event |
| DGFiP scrutiny | Cross-checked at disposal against cumulative impairments | Reconstitution of the tax basis required |
The DGFiP regularly audits the reconciliation between cumulative accounting impairments and the fiscal long-term loss recognised at disposal. Discrepancies must be documented in the tax file, particularly when impairments have been booked over multiple years before the disposal event.
8. 2026 watchpoints#
- Finance Act 2026 (LFI 2026): no structural modification of the Copé niche or the symmetric loss regime has been enacted.
- QPFC calculated on gross gains: even if the year's net long-term result is nil, the 12% recharge applies to each disposal's gross gain.
- 10-year expiry: long-term losses recorded in 2016 expire in 2026 — groups that experienced portfolio writedowns during 2015-2016 must urgently review their 2058-B carryforward schedules.
- Reinforced anti-abuse enforcement: intra-group disposals followed by rapid external exits are under heightened DGFiP scrutiny.
- ETNC annual list: verify on impots.gouv.fr each January before any disposal of shares in a non-EU/non-treaty entity.
- EU minimum taxation (Pillar Two / GloBE): for groups above the €750M revenue threshold, the 3% effective rate on equity gains may interact with the 15% global minimum tax top-up. Monitor OECD and EU guidance on the qualified domestic minimum top-up tax (QDMTT) for French entities.
9. Director decision framework#
| Situation | Recommended action |
|---|---|
| Winning and losing disposals in same year | Execute both in the same financial year to maximise LT compensation |
| Losing participation, no LT gain expected within 10 years | Consider disposing before the 2-year threshold (loss then deductible at 25%) |
| Participation held in an ETNC | Verify annual ETNC list before any disposal — no Copé niche available |
| Tax-consolidated group with neutralised intra-group LT losses | Model the perimeter exit consequences before any restructuring |
| Long-term loss carryforward unused for > 8 years | Plan a qualifying gain disposal before the 10-year expiry |
| High accounting impairment, disposal not yet executed | Do not confuse impairment with a realised fiscal loss — IS treatment arises only at disposal |
Operational checklist:
- Annual census of equity participations: original cost, net book value, estimated disposal value
- Verify qualification (participation vs. portfolio) and holding period for each position
- Check ETNC list (CGI Art. 238-0 A) each January
- Pre-calculate QPFC on gross gains before offset for each planned disposal
- Complete form 2058-B in the annual corporate tax return, even in years with no disposal
- Manage disposal calendar in advance of fiscal year-end
Closing thoughts#
The Copé niche provides a structurally significant tax advantage — a 3% effective rate versus 25% — but its symmetric treatment of long-term losses imposes an active portfolio management discipline that holding companies frequently underestimate. The non-deductibility of long-term losses, the QPFC calculated on gross gains rather than net results, and the 10-year expiry of loss carryforwards are three mechanisms that regularly generate unexpected tax costs during portfolio restructurings.

Frequently asked questions
Qu'est-ce que la « niche Copé » et comment fonctionne-t-elle en 2026 ?
La niche Copé désigne le régime fiscal favorable des plus-values à long terme sur titres de participation (CGI art. 219 I a quinquies). Les plus-values nettes à long terme réalisées par une société soumise à l'IS lors de la cession de titres de participation détenus depuis au moins 2 ans sont exonérées d'IS, sous réserve de la réintégration d'une quote-part de frais et charges (QPFC) de 12 % imposable à taux plein de 25 %. Taux d'imposition effectif global : 3 % au lieu de 25 %. En 2026, aucune modification structurelle de ce régime n'a été adoptée par la LFI 2026.
Comment fonctionne le traitement asymétrique des moins-values à long terme sur titres de participation ?
Par symétrie délibérée, les moins-values à long terme sur titres de participation détenus depuis ≥ 2 ans ne sont pas déductibles du résultat imposable au taux normal de 25 %. Elles s'imputent uniquement sur des plus-values nettes à long terme de même nature, au titre de l'exercice de réalisation ou des 10 exercices suivants (CGI art. 39 quaterdecies). Une moins-value de 200 000 € ne réduit pas l'IS de 50 000 € — elle reste « bloquée » jusqu'à une future plus-value long terme dans le délai de 10 ans. Passé ce délai, elle est définitivement perdue.
Quels titres sont éligibles au régime des titres de participation (niche Copé) ?
Sont automatiquement qualifiés de titres de participation : (1) titres représentant au moins 5 % du capital de la société émettrice ; (2) titres ouvrant droit au régime mère-filles (art. 145 CGI) ; (3) titres reçus en contrepartie d'apports partiels d'actifs sous le régime de faveur ; (4) titres comptablement classés en participations (compte 261, PCG art. 211-3). Sont exclus : titres de placement, OPCVM, SPI non cotées, titres dans un ETNC (art. 238-0 A CGI). La qualification doit être documentée de manière contemporaine à l'acquisition.
Mon holding détient des titres d'une filiale étrangère — la niche Copé s'applique-t-elle ?
Oui, sous réserve que les titres soient qualifiés de participation au sens fiscal français (≥ 5 % capital ou régime mère-filles) et que la société émettrice ne soit pas implantée dans un État ou Territoire Non Coopératif (ETNC) au sens de l'article 238-0 A du CGI. Pour les holdings françaises détenant des filiales dans l'UE ou dans des juridictions conventionnées (UK, USA, Suisse, Singapour, Canada), la niche Copé s'applique pleinement. La liste des ETNC est mise à jour annuellement par arrêté ministériel — vérification impérative avant toute cession.
Comment la dépréciation comptable des titres de participation se distingue-t-elle de la moins-value fiscale ?
Ce sont deux réalités distinctes. La dépréciation comptable (compte 686, art. 214 du règlement ANC 2014-03) est constatée annuellement sur la base d'un test de valeur, sans incidence fiscale IS tant que les titres ne sont pas cédés. La moins-value fiscale long terme n'est réalisée qu'à la cession effective : elle correspond à la différence entre le prix de cession et la valeur fiscale d'origine. La DGFiP contrôle régulièrement la cohérence entre les dépréciations comptables cumulées et la moins-value fiscale constatée à la cession — les écarts doivent être documentés dans le dossier fiscal.
