Management incentive plans in Luxembourg: sweet equity, vehicles and the tax on exit

A management incentive plan is a share deal with an employment shadow

When a private equity fund buys a company, it asks the management team to invest alongside it. The fund puts most of its money into preferred instruments that earn a fixed return. The managers buy ordinary shares, the sweet equity, for a small amount. If the exit goes well, the ordinary shares take everything above the fixed return, and a EUR 50,000 cheque becomes EUR 400,000 or more. Family offices do the same with an outside CEO.

In Luxembourg the tax answer for a resident manager is attractive and simple to state: a gain on privately held shares is tax-free after six months if the stake is no more than 10%, and taxed at half the global rate above that. The tax authorities and courts look at whether the manager paid fair value, whether the money was at risk, and whether the return really came from the shares or from the job. If the answer is the job, the gain is employment income at up to 45.78%, with social security.

Sweet equity, ratchets, tracking shares and alphabet classes

Sweet equity and the institutional strip. A typical Luxembourg buyout TopCo is an S.à r.l. or an SCA. The sponsor funds it mostly with shareholder loans, convertible or non-convertible preferred equity certificates (CPECs or PECs) or preferred shares carrying a fixed coupon, often 8% to 12% a year. That money is the institutional strip. Ordinary shares carry what is left after the strip has been repaid with its coupon. Managers buy ordinary shares, sometimes with a thin slice of the strip.

Below a large preferred layer, ordinary shares are cheap at entry and leveraged at exit. A low price is legitimate only if it reflects that structure, not a gift.

Ratchets. A ratchet gives management a larger share of exit proceeds once the sponsor reaches a return threshold, for example 2.5 times its money or a 25% IRR. It has value at entry, even if out of the money, and that value must be paid for or it is a benefit in kind.

Alphabet classes. Luxembourg companies often issue classes A to J so that cash can be returned by redeeming and cancelling one whole class. In its judgment of 14 June 2023 (no. 45759C), the Administrative Court accepted that the redemption of an entire class followed by its cancellation is a partial liquidation, not a dividend, provided the price is the fair value of the class and the operation has an economic justification. If either fails, the payment is a hidden distribution with 15% withholding tax.

Law and practice: Law of 10 August 1915 on commercial companies (share classes, redemption and cancellation of own shares); LIR Articles 97 and 101; Administrative Court, 14 June 2023, no. 45759C, summarised by CMS Luxembourg and Loyens & Loeff.

Direct holding, a management S.à r.l. or an SCSp

A sponsor rarely wants twenty managers on its TopCo register. Management shares are therefore pooled. The choice of pool decides how each manager is taxed.

Special limited partnership (SCSp). The usual choice. Its partnership agreement can mirror the MIP rules line by line. For income tax it is transparent: each manager is treated as holding a share of the TopCo shares held by the SCSp. Under Article 14 of the income tax law (LIR) a partnership is treated as carrying on a business if a corporate general partner holds an interest of 5% or more, so the general partner, usually a small S.à r.l., keeps a minimal interest. Because the partners look through, a manager with 30% of the SCSp that holds 20% of TopCo has an indirect 6% of TopCo, and stays below 10%.

S.à r.l. ManCo. An opaque ManCo is costly at exit. The ManCo sells its TopCo shares and pays corporate income tax on the gain, 23.87% in Luxembourg City in 2026, unless the participation exemption applies: a stake of at least 10% or an acquisition price of at least EUR 6 million, held for twelve months. A management pool usually meets neither test. The cash then reaches the managers as dividends or liquidation proceeds, taxed again.

Law and practice: LIR Article 14(4) (commercial partnerships, 5% rule), Articles 100 and 166; Circular L.I.R. no. 14/4 of 9 January 2015 on SCS and SCSp; Law of 10 August 1915, Articles 320-1 et seq. (SCSp). See also our guide to the SCSp as a fund vehicle.

Valuation at entry and the benefit in kind risk

Luxembourg has no special regime for management equity. Since the circular on stock options and warrants (L.I.R. no. 104/2 of 29 November 2017) was withdrawn with effect from tax year 2021, employee equity has been taxed under the general rules. Anything an employee receives because of employment, in cash or in kind, is employment income under Article 95 LIR. Shares bought below their value are such an advantage.

The rule in practice. If the manager pays fair value, there is no benefit at entry and any later gain is a gain on shares. If the manager pays less, the shortfall is salary in the year of acquisition. The employer withholds tax and social security on it, up to the ceiling. Shares sold cheaply by the sponsor rather than the employer are caught too, if granted because of the job.

What fair value means for sweet equity. The ordinary shares are worth little because of the strip above them, and that is legitimate. A sound entry file values the whole capital structure at the deal price, allocates it across the classes by an option-pricing or probability-weighted method, and documents the lack of marketability and the leaver terms. The ratchet and any tracking class need their own value.

Options are different. A non-transferable option is taxed at exercise as employment income on the spread. Bill 8782, filed on 1 July 2026, would codify that rule, add a lock-up discount of up to 20%, and create a regime for young innovative companies taxed at sale at a quarter of the global rate. It is not adopted and targets start-up options, not buyout sweet equity; see our comparison of Benelux option regimes.

Not carried interest. The carry regime in force from tax year 2026 covers individuals who manage alternative investment funds. A portfolio company's CEO or CFO is outside it. Sponsor staff are under the carry rules for their carry only.

Law and practice: LIR Articles 95 and 104 (employment income and benefits in kind); circular L.I.R. no. 104/2 of 29 November 2017, withdrawn from 2021; bill 8782 filed 1 July 2026, summarised by Loyens & Loeff; carried interest law adopted as bill 8590 on 22 January 2026.

How the exit is taxed for a Luxembourg resident

For a Luxembourg resident holding shares privately, three facts decide the tax: the holding period, the size of the stake, and the character of the gain.

The 10% test. A participation is substantial if the seller, alone or with a spouse or partner and minor children, held more than 10% of the capital, directly or indirectly, at any time in the five years before the sale. A ratchet that lifts a CEO from 9% to 12% before exit changes the result.

The half global rate. The global rate is the average rate on the manager's total taxable income, the gain included. Half of it applies to the gain after the allowance. With the top marginal rate at 45.78% including the solidarity surcharge, the effective rate stays below about 22.9%. A 1.4% dependency contribution is collected on taxable investment income and gains.

Budget bill 8800. Filed on 7 October 2026, it would extend the six-month period to twelve months from tax year 2027, for the speculative gain rule, for access to the half global rate and for non-residents. Published summaries mention no transitional rule. The bill is still before Parliament in November 2026.

Dividends. Half of a dividend from a fully taxable Luxembourg, EU or treaty company is exempt; the first EUR 1,500 of investment income a year (EUR 3,000 for a couple) is exempt too. The 15% withholding tax is credited.

Law and practice: LIR Article 99bis (speculative gains), Article 100 (substantial participations), Article 101 (liquidation), Article 115 no. 15a (50% dividend exemption), Articles 130 and 131 (allowance and half global rate); bill 8800, summarised by Stibbe and Goodwin; 2026 class 1 scale; figures computed by us.

French, Belgian, German and Dutch managers of a Luxembourg TopCo

Luxembourg domestic law. A non-resident is taxed on a gain from shares in a Luxembourg company only if the stake is substantial, more than 10%, and either the shares are sold within six months of acquisition, or the seller was a Luxembourg resident for more than 15 years and became non-resident less than five years before the sale. Bill 8800 would extend the six months to twelve.

Treaties. Where domestic law does bite, the treaties usually give the gain to the country of residence. The 2018 France–Luxembourg treaty allows Luxembourg to tax only a participation of 25% or more held by someone who was resident in Luxembourg in the five years before the sale. The treaty with the Netherlands keeps a source-state right for former residents with substantial holdings. The treaties with Belgium and Germany follow the general rule that gains on shares are taxed where the seller lives, with exceptions for companies rich in real estate. Check the text.

The home country is the real battleground, and a Luxembourg structure does not change that. See the note on Belgian executives and our guide to moving with equity.

Dividends and entry. Dividends from TopCo to a non-resident bear 15% Luxembourg withholding tax, credited at home under the treaty; partial liquidation proceeds do not. A discount at entry is employment income, taxed in Luxembourg for the days the manager works there.

Law and practice: LIR Article 156 no. 8 (non-residents' gains on substantial participations); France–Luxembourg treaty of 20 March 2018, Article 13, summarised by Arendt; Netherlands treaty per Chambers International Tax 2026; French CGI Article 163 bis H as amended by the 2026 Finance Law, per CMS Francis Lefebvre. See also dividends to non-residents.

Leaver terms, the MIP rules and how the exit works

Leaver provisions decide the character. Every MIP says what happens when a manager leaves. A good leaver usually sells at fair value; a bad leaver, after resignation or dismissal for cause, at the lower of cost and fair value. On their own these clauses do not make the gain salary: the manager invested at fair value and bears the loss.

The risk rises when the return depends on staying rather than on the shares: extra shares granted for remaining until exit, a ratchet only employees can hold or a guaranteed floor. Then the tax authorities can argue that part of the gain is pay for services under Article 95 LIR, taxed at progressive rates, and that social security is due. No statute draws the line; the documents must.

• Shareholders' agreement. Transfers, drag and tag, leavers and the waterfall; see our note on shareholders' agreements.
• MIP rules or SCSp agreement. Who may invest, allocation, vesting, leaver prices, the fair-value method and the role of the general partner.
• Articles of TopCo. Share classes, ratchet conversion, redemption of classes and the authorised capital to issue them.
• Valuation report. At entry and at each later allocation, on the actual capital structure.
• Subscription file. Proof that each manager paid with own funds; a sponsor-financed loan must carry arm's length interest and recourse.

Exit mechanics. On a sale, the sponsor exercises its drag-along and every manager sells on the same terms per share of each class; tag-along protects managers if the sponsor sells alone. The buyer often asks managers to roll part of their proceeds.

Rollover. Managers exchange part of their shares for shares in the buyer's new TopCo. For a resident below 10% after the holding period, the exchange is a disposal but the gain is exempt; the new shares are acquired on the exchange date, so a new holding period starts, twelve months if bill 8800 passes. For a substantial participation, Article 22bis LIR, applied to private holdings, can defer the gain on a qualifying share-for-share exchange; the conditions are strict, so check them before signing.

Law and practice: LIR Articles 22bis, 95 and 102; Circular on Article 22bis of 27 July 2021; Law of 10 August 1915 on transfer restrictions in S.à r.l. and SCSp. Exit structuring at holding level: selling a business through a SOPARFI.
