Gifting shares before a sale: purging the capital gain without abuse of law

Gifting shares before selling purges the latent capital gain, provided the donor truly parts with them.

Introduction: gifting shares before the sale, the lever that erases the seller's capital gain

Should you sell your company and then pay tax on the capital gain, or first gift part of the shares to your children so that this tax is never due on the gifted portion? Gifting shares before the sale, often called a gift-then-sale, consists of donating all or part of a company's shares before selling them, so that the latent capital gain attached to the gifted shares is purged, because under Article 150-0 A of the French General Tax Code a gift is not a taxable event. The donee acquires the shares at their market value on the day of the gift, and when they later sell at that same price, their capital gain is close to zero.

« In order to restore its true character, the tax authority is entitled to set aside, as unenforceable against it, transactions constituting an abuse of law. », Article L64 of the French Book of Tax Procedures.

The stakes in 2026 rest on three converging factors. First, the finance act did not overhaul the taxation of sales but reinforced the requirements of economic substance and the tax authority's scrutiny of wealth-planning structures. Second, the boundary between legitimate optimisation and abuse of law now turns on whether the donor genuinely parts with the shares, an area the French Council of State has precisely mapped out. Third, for a Franco-Swiss owner, the French reflex of purging the gain makes no sense across the border, where private capital gains are already tax-exempt. This article sets out the definition, origin, motivations, method, timing, advantages and limits of gifting shares before a sale, the five mistakes to avoid, two worked cases for France and Switzerland, a word from the founder, a ten-question FAQ and an operational summary.

Definition: what is gifting shares before a sale?

Gifting shares before a sale is a two-step wealth operation. In the first step, the owner gifts part or all of their shares, most often to their children, through a deed of gift or a shared gift executed before a notary. In the second step, the company is sold, and it is now the donees who sell the shares they received. The tax effect sought is the purge of the latent capital gain on the gifted portion, since the gift transfers ownership of the shares at their market value on the day, which becomes the new cost basis for computing the donee's capital gain.

The mechanism rests on a precise interaction of two taxes. A direct sale of the shares by the owner triggers tax on the securities capital gain, at the flat tax of 30%, being 12.8% income tax and 17.2% social levies, increased where applicable by the exceptional contribution on high incomes. The gift, by contrast, does not trigger this capital-gains tax, but transfer duties on gifts, mitigated by the allowance of €100,000 per parent and per child, renewable every fifteen years. The structure is only worthwhile when the capital-gains tax saving exceeds, or usefully complements, the cost of the gift duties the family would have borne anyway on transferring the business. The quality of the share valuation underpins the whole edifice.

Origin: from a notarial practice to a scheme framed by the courts

Gifting shares before a sale is neither a recent structure nor an exotic loophole. It follows mechanically from the logic of the securities capital-gains tax, which strikes only the gain realised on a sale for value, and not a transfer made without consideration. Notarial firms have long used it to prepare the transfer of a family business, combining succession planning with tax efficiency.

Its legal security has been built through case law. The French Council of State laid down a now settled principle: the tax authority may challenge a gift-then-sale only on the ground of fictitiousness, that is a simulated gift, and not on the ground that the operation has an exclusively tax purpose. In other words, choosing to gift before selling in order not to pay capital-gains tax is not in itself abusive. What is sanctioned is the sham gift, where the donor in reality recovers the sale price. The introduction of the mini abuse-of-law rule of Article L64 A of the Book of Tax Procedures, targeting operations with a mainly tax purpose, revived concern, but the tax authority has confirmed that a genuine gift-then-sale, marked by an irrevocable disposal, falls outside its scope.

Why gift before selling

First, the purge of the capital gain. On the gifted portion, the 30% tax that would have struck the latent gain disappears, since the donee sells at a value equal to that used for the gift duties. On a large gain, the saving runs into hundreds of thousands of euros.

Second, early transfer. The gift removes the value from the owner's estate and places it in the hands of the next generation, before the sale turns the shares into cash that is often harder to transfer without later tax friction.

Third, flexibility of calibration. The owner chooses the gifted portion, from a few per cent to the whole, and keeps for themselves the fraction from which they wish to draw available proceeds. They may also gift only the bare ownership and retain the usufruct.

Fourth, optimisation of duties. Direct-line allowances, renewable every fifteen years, and the donor's ability to bear the duties without this constituting an additional gift, reduce the cost of the transfer.

Fifth, alignment with a family plan. The structure makes full sense when the family intended to transfer in any case: the sale becomes the occasion to purge the gain and prepare the succession in a single move, rather than suffering the tax and then facing the transfer of the net proceeds.

How a gift-then-sale is built

The build follows a rigorous sequence whose order is decisive. The first step is the valuation of the shares at their true market value, by a defensible multi-method approach, because this value serves both as the base for the gift duties and as the cost basis for the donee's future capital gain. An undervaluation exposes the parties to a reassessment on the duties, an overvaluation needlessly inflates the taxable base.

The second step is the gift itself, formalised by notarial deed, ideally as a shared gift to fix values among heirs and prevent disputes. The third step, crucial, is respect for the timing: the gift must be concluded and registered before the sale has become certain in its principle and price. A gift signed once the sale agreement is already sealed weakens the whole.

The fourth step is the sale, now carried out by the donees for the portion they hold, at a price consistent with the gift value. The fifth step is the fate of the proceeds: the donee must receive and be able to freely dispose of their share, without the donor recovering its substance. Where ownership is split, a usufruct-on-proceeds agreement drawn up beforehand organises the debt of restitution for the benefit of the bare owners. The sixth step is the preservation of evidence, deeds, financial flows and decisions, which will document the reality of the disposal in the event of an audit. Our teams coordinate this sequence with the notary and the tax lawyer, as an extension of our financial structuring engagements.

When to use a gift-then-sale

The structure applies first when the latent capital gain is high, that is when the cost basis of the shares is low relative to their current value, a frequent situation for a founder who created the company with modest capital. It becomes particularly relevant when the owner has a family-transfer plan: gifting before selling achieves two aims at once.

It also suits configurations where the owner does not need the entire proceeds to fund their lifestyle or projects, and can therefore genuinely part with a fraction of the shares. Conversely, it is inadvisable when the seller needs all the proceeds, when the sale is already legally committed, or when the family relationship makes an irrevocable disposal hard to accept. Gifting before a sale finally combines with other levers, such as the contribution-then-sale under Article 150-0 B ter or the Dutreil pact, each answering a different logic that must be articulated rather than stacked.

Donation, contribution-then-sale or retirement relief: which lever to choose

Gifting before a sale is only one of the levers available to an owner who sells. Three logics coexist and answer different projects, so that confusing them often leads to the wrong choice. Gifting before a sale purges the capital gain and transfers the value to the next generation, but it is irrevocable and requires genuinely parting with the shares. The contribution-then-sale under Article 150-0 B ter does not purge the gain but defers its taxation, by placing the shares in a holding company controlled by the owner, subject to reinvesting a substantial part of the proceeds in an economic activity if the sale occurs within three years. The relief for an owner retiring, provided by Article 150-0 D ter, applies a fixed allowance of €500,000 on the capital gain, subject to an actual retirement within the required timeframe.

The choice is read against the seller's real project. Those who want to transfer to their children favour gifting before a sale. Those who want to reinvest while keeping control of their capital lean towards the contribution-then-sale. Those who cease their activity and wish to cash out use the retirement relief. These levers do not, moreover, exclude one another: a gift of part of the shares can combine with retirement relief on the retained portion, provided the specific conditions of each mechanism are carefully articulated.

Lever	Tax effect	Trade-off	When to choose it
Gift before sale	Purges the gain on the gifted shares	Irrevocable, gift duties	You want to transfer to your heirs
Contribution-then-sale (150-0 B ter)	Defers taxation of the gain	Holding, reinvestment if sale under 3 years	You want to reinvest while keeping control
Retirement relief (150-0 D ter)	€500,000 allowance on the gain	Actual retirement within the deadlines	You cash out on ceasing activity

Who to call on

Three criteria should guide the choice of advisers. The first is the independence of the valuer: the value of the shares, the bedrock of the structure, must not be set by a party with an interest in the transaction, on pain of weakening both the gift duties and the future capital gain. The second is multidisciplinary coordination, because the operation mobilises a notary for the deed, a tax lawyer for the security of the scheme, and a valuer for the value. The third is knowledge of the Franco-Swiss context, essential as soon as the owner, the company or the heirs have a connection to Switzerland.

Hectelion acts as an independent boutique firm, alongside your usual advisers, to produce a multi-method valuation aligned with IVSC standards and defensible before the tax authority, and to secure the economic consistency of the whole. Our economic independence from traditional financial intermediaries guarantees an objective value, neither pushed down to minimise the duties, nor inflated to flatter a seller. We support operations of 2 to 500 MCHF, working closely with the notary and lawyer who carry the deeds.

Advantages: purge, transfer, flexibility

The first advantage is fiscal and immediate: the latent gain on the gifted shares is erased, which can represent a substantial saving on a gain built over decades of entrepreneurship. The second advantage is patrimonial: the gift organises the transfer of the business or its value to the next generation, with renewable allowances and the ability to fix balances among heirs through a shared gift. The third advantage is flexibility: the gifted portion, the use of split ownership and the donor's assumption of the duties allow the structure to be finely adjusted to the family's needs and the seller's desired liquidity. Well conducted, the structure turns a tax constraint into a mastered transfer project.

Limits: irrevocability, gift duties, recharacterisation

The first limit is irrevocability: to give is to part definitively, without being able to take back the shares nor, above all, the price of their sale. An owner who hopes to quietly recover the funds has no place in this structure. The second limit is the cost of the gift duties, which can be high when the gifted value far exceeds the allowances, and which must be weighed against the capital-gains saving to check that the operation is genuinely worthwhile.

The third limit is the risk of recharacterisation as abuse of law when the gift is fictitious, notably in the event of the donor recovering the proceeds or of a reversed chronology. The penalty is heavy: reinstatement of the capital-gains tax and a surcharge that can reach 80%. The fourth limit, essential for a Franco-Swiss owner, is the unsuitability of the structure to the Swiss regime, where private capital gains are already exempt, which deprives the purge of any purpose and shifts the stakes to other risks, such as indirect partial liquidation.

The 5 mistakes to avoid

Mistake 1: Gifting after the sale has become certain

Timing is the pillar of the structure. If the gift occurs once the sale agreement is signed, the price is set and the sale is certain in principle, the tax authority considers that the gain was realised by the donor themselves, who merely passed on the proceeds of an already secured sale. The gift must precede the sale, and a sufficient time gap, together with a negotiation still open at the time of the gift, strengthens the security of the operation.

Mistake 2: Recovering the sale proceeds

This is the fatal mistake. When the donor recovers, directly or indirectly, the proceeds from the sale of the gifted shares, the gift is deemed fictitious and the structure collapses. Case law is consistent: the immediate recovery of the price, even dressed up after the fact with a usufruct-on-proceeds agreement, reveals the absence of donative intent and characterises abuse of law. The donee must receive and be able to use their share.

Mistake 3: Neglecting the valuation of the gifted shares

The value used at the time of the gift plays a dual role: it sets the transfer duties and becomes the donee's cost basis. An approximate or complacent valuation exposes the parties to a reassessment on the duties if too low, and needlessly inflates the taxable base if too high. A multi-method, documented and independent valuation is the best protection.

Mistake 4: Confusing the French and Swiss regimes

Mechanically applying the gift-then-sale to a Swiss SME is an analytical error. Private capital gains being exempt there, there is no gain to purge, and the structure brings only a cost of gift duties and needless complexity, while leaving intact the real Swiss risks of indirect partial liquidation and transposition. The reasoning must always start from the tax regime applicable to the seller.

Mistake 5: Overlooking the usufruct-on-proceeds agreement and the debt of restitution

Where the owner gifts only the bare ownership and retains the usufruct, the sale of the split-ownership shares raises the question of the fate of the proceeds. Absent a reinvestment in a split-ownership asset, a usufruct-on-proceeds agreement must be drawn up beforehand, with a debt of restitution for the bare owners, enforceable and documented. Improvised after the sale to justify a recovery of the funds, it protects nothing and instead fuels the suspicion of fictitiousness.

Case 1: a shared gift of 40% before the sale of a family SME at €4,000,000

A French owner holds 100% of an SME valued at €4,000,000. They had set up the company with capital of €200,000, which is their cost basis, giving a latent capital gain of €3,800,000. If they sell all their shares without any planning, the gain of €3,800,000 is subject to the flat tax of 30%, being a tax of €1,140,000, and no transfer is organised. To this sum is added the exceptional contribution on high incomes, of 3 to 4% above the thresholds, being an extra cost of the order of €100,000 to €150,000 on a gain of this magnitude, which further weighs on the plain sale.

The owner chooses another path. Before any sale, while the negotiation with the buyer remains open, they make a shared gift of 40% of the shares, being a value of €1,600,000, to their two children, at €800,000 each. On this gifted portion, the gain is purged: when the children sell their shares at €1,600,000, their gain will be near zero, since their cost basis is the gift value. The capital-gains tax that would have struck these 40%, being a gain of €1,520,000 taxed at 30%, represented €456,000: that sum disappears.

The cost of the transfer is that of the transfer duties on gifts. For each child, the taxable base is €800,000 less the €100,000 allowance, being €700,000. Under the direct-line scale, the duties amount to about €152,962 per child, being close to €305,924 for the two. The owner then sells the 60% they retained, for €2,400,000, paying the flat tax on a gain of €2,280,000, being €684,000.

The outcome is telling. Without the structure, the total tax is €1,140,000 and nothing is transferred. With the structure, the total borne is €684,000 of flat tax on the retained 60%, plus €305,924 of gift duties, being €989,924, while transferring €1,600,000 to the two children with a purged gain. The owner thus saves €150,076 in tax and organises, in the same move, the transfer of €1.6 million. Using split ownership or having the donor bear the duties, allowed without an additional gift, would further improve this result. The condition remains absolute: the gift must precede the sale and the children must freely dispose of their proceeds.

Taxable portion, after the €100,000 allowance per child	Applicable direct-line rate
Up to €8,072	5%
€8,072 to €12,109	10%
€12,109 to €15,932	15%
€15,932 to €552,324	20%
€552,324 to €902,838	30%
€902,838 to €1,805,677	40%
Above €1,805,677	45%

Applied to Case 1: on a base of €700,000 per child, the duties reach about €152,962, being close to €305,924 for the two children.

Scenario	Total tax borne	Value transferred to children
Plain sale of 100% of the shares	€1,140,000	€0
Shared gift of 40% then sale	€989,924, of which €684,000 flat tax and €305,924 duties	€1,600,000
Difference	€150,076 less tax	€1,600,000 transferred

Illustrative assumptions, excluding the exceptional contribution on high incomes, 2026 direct-line scale. Amounts depend on each family's own situation.

Case 2: in Switzerland, a gain already exempt but the threat of indirect partial liquidation

A Geneva entrepreneur holds 100% of an SME valued at CHF 6,000,000, of which about CHF 2,000,000 of cash and non-operating assets, distributable. Tempted to reproduce the French structure, they consider gifting part of their shares to their children before selling. The Swiss analysis leads to the opposite conclusion to that of France.

In Switzerland, the gain realised on the disposal of shares held in the taxpayer's private wealth is exempt from tax under Article 16 paragraph 3 of the Federal Act on Direct Federal Taxation. In other words, by selling their shares, the entrepreneur bears no tax on the gain. There is therefore no capital gain to purge, and gifting before the sale loses all fiscal purpose from the seller's standpoint. Worse, it would add the possible cost of a cantonal gift tax, even if the direct line is often exempt in Geneva, without neutralising the real risk of the operation.

That risk is indirect partial liquidation. If the buyer is a company that records the participation in its business wealth, if the sale covers at least 20% of the capital, and if, within five years, non-operating substance already distributable at the time of the sale is distributed with the seller's involvement, the sale proceeds are recharacterised as taxable investment income within the meaning of Article 20a of the same act. On the CHF 2,000,000 of distributable substance, a recharacterisation would result, after partial taxation of dividends, in a taxable base of the order of CHF 1,400,000, and a tax that can reach several hundred thousand francs at the Geneva marginal rate. Gifting before the sale offers no protection against this risk.

The right Swiss reflex is different. It consists of securing the characterisation of the gain rather than purging a tax that does not exist: contractually locking in the absence of any distribution of substance for five years, providing for compensation in the event of a breach, and confirming the tax treatment through a cantonal tax ruling. Transfer to the children, if desired, then follows a succession logic, handled by a gift or an inheritance pact for family reasons, and not a purge of the gain. This contrast illustrates a simple rule: a tax lever is always reasoned from the applicable regime, never by imitation of a foreign practice. We develop this comparison in our analysis of family business transfers in Switzerland.

Criterion	France	Switzerland
Regime of the sale gain	Gain taxed at the 30% flat tax, plus the high-income contribution	Private capital gain exempt (Art. 16 para. 3 DFTA)
Effect of gifting before the sale	Purges the latent gain on the gifted shares	No fiscal purpose, no gain to purge
Cost specific to the structure	Transfer duties on gifts, €100,000 allowance	Cantonal gift tax, often nil in the direct line
Real risk to watch	Fictitiousness of the gift, recovery of the proceeds (abuse of law)	Indirect partial liquidation and transposition (Art. 20a DFTA)
Right reflex	Gift first, genuinely part with the shares, document	Secure the characterisation of the gain through structuring and a ruling

A word from the founder

« Gifting before a sale is one of the rare structures where tax optimisation and family transfer move hand in hand. But I see too many owners engage in it thinking first of the tax and only then of their children. It is the opposite that works: you gift because you want to transfer, and the purge of the gain rewards that choice. »

« The red line is always the same. The day you try to take back with one hand what you gave with the other, the gift becomes fictitious and everything collapses. I invite every owner to ask a simple question before signing: am I truly ready to part with these shares and their price, definitively? If the answer is no, this structure is not the right one. »

« For our Franco-Swiss clients, the first task is often to unlearn. What is an obvious reflex in France makes no sense in Switzerland, where the private gain is already exempt. Our role is to start from the real regime, value the shares rigorously and build a structure that withstands an audit, not to duplicate a recipe. »

FAQ: the 10 essential questions on gifting shares before a sale

Introduction: what to remember before the questions

Gifting shares before a sale is a legal and proven structure, but a demanding one. Its success rests on three cumulative conditions: a real and irrevocable gift, prior to a still uncertain sale, and a donee who freely disposes of their proceeds. The following questions answer owners' most frequent queries, systematically distinguishing the French context, where the purge makes sense, from the Swiss context, where it does not.

Q1: Is gifting before a sale legal or is it abuse of law?

It is entirely legal. The French Council of State has held that the tax authority may challenge it only on the ground of the fictitiousness of the gift, and not because it pursues a tax purpose. Choosing to gift before selling in order not to pay capital-gains tax is not abusive. What is abusive is the sham gift, where the donor recovers the price.

Q2: In what order should you gift and then sell?

The gift must imperatively precede the sale. It is the donee who then sells the shares received. A reversed order, or a gift occurring once the sale is already certain, exposes the parties to a recharacterisation, the authority considering that the gain was realised by the donor.

Q3: How much time to leave between the gift and the sale?

No legal delay is set, but the larger the time gap, the lower the risk of recharacterisation. The essential point is that the sale must not be certain in its principle and price at the time of the gift. A gift made while the negotiation genuinely remains open is far safer than a gift signed the day before the sale.

Q4: What gift duties will I pay?

Transfer duties on gifts apply to the gifted value, after an allowance of €100,000 per parent and per child, renewable every fifteen years, then under a progressive direct-line scale. The donor may bear these duties without this constituting an additional gift, which optimises the transfer. Do not confuse this with the temporary €100,000 allowance for cash gifts, in force until the end of 2026, which covers only cash allocated to certain uses, and not the gift of shares, which falls under the ordinary €100,000 direct-line allowance.

Q5: Can I recover the sale proceeds through a usufruct-on-proceeds?

This is the most sensitive point. A recovery of the price by the donor, even justified by a usufruct-on-proceeds agreement, is the main ground for recharacterisation when it reflects a recovery of the funds. Such an arrangement is admissible only if it results from a split ownership organised beforehand, with a documented debt of restitution, and not from a late device intended to take back the funds.

Q6: Can I gift only the bare ownership and keep the usufruct?

Yes, split ownership is common and lets the owner keep an income. One must, however, anticipate the fate of the proceeds on the sale of the split-ownership shares, either by reinvestment in a split-ownership asset, or by a usufruct-on-proceeds agreement drawn up before the sale, failing which the structure weakens.

Q7: Who signs the sale deed if I have gifted the shares?

It is the donees, now owners, who sell the portion they hold. The owner sells only the shares they retained. Where ownership is split, usufructuary and bare owner act together in the deed, according to the terms provided by the agreement.

Q8: Does gifting before a sale work in Switzerland?

No, not in its French logic. Private capital gains being exempt in Switzerland, there is no gain to purge. The gift then brings only cost and complexity, without neutralising the real Swiss risks of indirect partial liquidation and transposition. Transfer there answers succession motives, not tax ones.

Q9: Is a tax ruling needed to secure the operation?

In France, a ruling can confirm certain elements, even if the security rests above all on the reality of the disposal. In Switzerland, the cantonal tax ruling is a central tool to secure the characterisation of the gain and rule out the risk of indirect partial liquidation. In both cases, an independent valuation of the shares is the prerequisite.

Q10: How to value the gifted shares to avoid a reassessment?

By a multi-method valuation, aligned with IVSC standards, combining income, multiples and asset approaches, documented and carried out by an independent third party. This value underpins both the gift duties and the donee's cost basis: it must be defensible before the tax authority, neither understated nor overstated.

Conclusion: gift first, sell next, and never take back with one hand what you gave with the other

Gifting shares before a sale is one of the most effective levers for combining the purge of the capital gain with the transfer of a family business. Its power in France rests on a simple articulation: the gift not being a taxable event, it erases the latent gain on the gifted shares, which the donee then sells at their value. But this efficiency has a price, irrevocability, and a condition, the reality of the disposal. The owner who is not ready to part definitively with the shares and their price must forgo the structure. For a Franco-Swiss owner, vigilance is twofold, because what goes without saying in Paris makes no sense in Geneva, where the private gain is already exempt and where the stakes shift to the characterisation of the gain.

Article summary

Gifting shares before a sale consists of donating shares before selling them, in order to purge the latent gain on the gifted portion, the gift being subject not to capital-gains tax but to transfer duties on gifts, mitigated by the €100,000 direct-line allowance. The structure is secure only on three conditions: a real and irrevocable gift, prior to a still uncertain sale, and a donee who freely disposes of their proceeds. The donor's recovery of the funds, even through a late usufruct-on-proceeds, is the main ground for recharacterisation as abuse of law, with a surcharge that can reach 80%.

The worked French case shows that a shared gift of 40% before the sale of an SME valued at €4,000,000 saves €150,076 in tax while transferring €1,600,000 to the children. The Swiss case demonstrates the opposite: private capital gains being exempt, gifting before a sale loses all fiscal purpose there and leaves intact the risk of indirect partial liquidation, which must be handled through structuring and a ruling, not a purge.

The success of the operation rests on an independent, multi-method valuation of the shares, the bedrock of both the gift duties and the future capital gain, and on close coordination between the valuer, the notary and the tax lawyer. Hectelion provides this valuation and structuring, in France as in Switzerland, for operations of 2 to 500 MCHF, in full independence from traditional financial intermediaries.
