Dry Income in Employee Equity: Section 19a EStG After the ZuFinG

The problem

Employee equity is a standard tool for startup compensation. In the United States, stock option grants with favorable tax treatment have been routine for decades. In Germany, the same transaction creates a tax trap.

When a startup grants shares to an employee at a discount or for free, the difference between fair market value and the price paid is taxed as wage income under Section 19 EStG. The marginal tax rate reaches 45% plus solidarity surcharge. The employee owes this tax immediately, even though the shares cannot be sold, there is no market, and the company may still fail. This is the dry income problem (Dry-Income-Problematik).

For years, the standard workaround was the VSOP (Virtual Stock Option Plan). VSOPs avoid the problem entirely by granting no actual equity. But this comes at a cost: VSOP payouts are taxed as ordinary wage income at up to 45%, rather than at the 25% capital gains rate that applies to actual shares. The tax differential can amount to tens of thousands of euros per employee.

The legislature recognized this problem. In 2021, Section 19a EStG was introduced through the Fondsstandortgesetz (Fund Location Act). In 2024, the Zukunftsfinanzierungsgesetz (ZuFinG) substantially expanded its scope. This analysis examines whether the reformed provision actually solves the dry income problem, where gaps remain, and what structuring options exist.

Legal framework

Section 19a EStG: the deferral mechanism

Section 19a EStG allows qualifying companies to grant equity to employees without triggering immediate wage taxation. The taxable benefit (geldwerter Vorteil) is recognized but not assessed until a triggering event occurs.

The provision applies to companies that do not exceed the following thresholds in the year of transfer or any of the six preceding years: annual revenue of EUR 100 million, annual balance sheet total of EUR 86 million, and 1,000 employees. The company must have been founded no more than 20 years before the transfer (Section 19a(3) EStG). The ZuFinG doubled the revenue and balance sheet thresholds and quadrupled the employee count from the original 2021 limits (EUR 50 million, EUR 43 million, 250 employees, 12 years).

Three events trigger subsequent taxation under Section 19a(4) EStG:

1. Transfer of the participation (sale, gift, or other disposition)
2. Expiry of 15 years after the original grant (extended from 12 years by the ZuFinG)
3. Termination of employment with the granting employer

If the employee has held the participation for at least three years at the time of the triggering event, the one-fifth rule (Fünftelregelung) under Section 34 EStG applies, providing limited rate mitigation.

Section 19a(4a): the employer liability option

The ZuFinG introduced a critical new mechanism in Section 19a(4a). If an employer irrevocably declares that it will assume liability for the wage tax owed on the participation, triggering events 2 and 3 (15-year expiry and termination) no longer apply. Only an actual transfer of the participation triggers taxation.

This provision was designed to solve the core dry income problem: an employee who holds shares indefinitely and cooperates with a willing employer should never face taxation without liquidity.

Frotscher/Geurts (EStG § 19a Rz. 55a) observes that this mechanism potentially allows perpetual deferral of taxation under Section 19a if the participation is held permanently. The commentary further notes that inheritance does not constitute a taxable transfer, since acquisition by inheritance under Section 1922(1) BGB is not a "gratuitous transfer" (unentgeltliche Übertragung) within the meaning of the statute.

Section 3 Nr. 39 EStG: the annual exemption

In addition to the deferral, Section 3 Nr. 39 EStG provides an annual tax exemption of EUR 2,000 for employee equity participation. The ZuFinG raised this from EUR 1,440. While helpful, this exemption is modest by international standards: Austria provides EUR 3,000, and Italy EUR 2,100, as Flick Gocke Schaumburg have noted in their analysis of the reform.

Konzernklausel (JStG 2024)

The Jahressteuergesetz 2024, enacted on 18 October 2024, addressed a significant limitation. Previously, only participations in the direct employer company qualified for Section 19a deferral. This excluded common structures where employees of an operating subsidiary receive shares in the parent holding company.

The JStG 2024 inserted a new sentence after Section 19a(1) sentence 2: shares in a group company within the meaning of Section 18 AktG now qualify, provided the size thresholds of Section 19a(3) are not exceeded by the group as a whole and no group company was founded more than 20 years ago. The provision applies retroactively from 1 January 2024.

Administrative view

The Federal Ministry of Finance published comprehensive application guidance on 1 June 2024 (BMF letter IV C 5 - S 2347/24/10001 :001), replacing the earlier guidance from 16 November 2021. This letter addresses the practical application of both Section 3 Nr. 39 and Section 19a EStG after the ZuFinG reform.

Key positions taken by the Finanzverwaltung include confirmation that the expanded size thresholds apply from 1 January 2024, that the 15-year deferral period also applies to participations transferred before 2024, and that Section 19a(4a) requires the employer's irrevocable declaration to be filed no later than the wage tax return following the triggering event.

The BMF letter notably does not address the interaction between Section 19a deferral and social insurance contribution obligations. This silence is significant, as discussed below.

Case law: BFH clarifies the boundary

On 22 January 2026, the Bundesfinanzhof published two decisions (both decided on 21 October 2025) that reshape the tax treatment of ongoing payments from employee participations.

In VIII R 13/23, the BFH held that ongoing profit distributions from a typical silent partnership (typische stille Gesellschaft) held by an employee constitute capital income under Section 20(1) Nr. 4 EStG, not wage income under Section 19 EStG. In VIII R 14/23, the court reached the same conclusion for interest payments from a mandatory profit participation right (Genussrecht), classifying them under Section 20(1) Nr. 7 EStG.

The BFH established three prerequisites for capital income classification:

1. Effective civil law formation of the participation arrangement (documented partnership or profit participation agreement)
2. Serious implementation of the contractual terms in practice
3. Independent economic substance distinct from the employment relationship

The court explicitly stated that high, profit-dependent returns do not by themselves justify reclassification as wage income. This overturns the practice of some local tax offices that treated above-market returns as disguised compensation.

These decisions do not directly address Section 19a. But they have significant implications for structuring: properly structured Genussrechte and silent partnerships now have BFH confirmation that their ongoing returns are taxed at the 25% capital gains rate, not the 45% wage rate. Combined with Section 19a deferral on the initial grant, this creates a powerful two-stage benefit.

Competing views

Three areas of genuine dispute emerge from the current legal landscape.

1. Residual dry income: the social insurance gap

Section 19a defers income tax. It does not defer social insurance contributions. When an employee receives equity, social insurance contributions on the monetary benefit may be due immediately, even if wage tax assessment is deferred.

This creates a partial dry income situation that the statute does not address. For an employee at the contribution ceiling (Beitragsbemessungsgrenze), the immediate social insurance burden may be manageable. For employees below the ceiling, the combined employer and employee social insurance contribution of approximately 40% on the benefit can be substantial.

The BMF letter of 1 June 2024 is silent on this interaction. The GAIA Law analysis notes that "social security contributions may be due immediately" despite Section 19a deferral, creating a compliance trap for employers who assume the dry income problem is fully resolved.

2. The termination trap

Section 19a(4a) allows employers to prevent taxation on termination by assuming wage tax liability. But this is an employer option, not an employee right. The employer's declaration must be irrevocable, creating a long-term contingent liability on the employer's balance sheet.

Dornbach characterizes this as a "Damocles sword" (Damoklesschwert) for employees: a departing employee who retains shares but loses employer cooperation faces immediate taxation at potentially the worst moment. Noerr's analysis (Voigt/Scheuch) identifies an additional enforcement risk: if a former employee becomes unreachable years later when the employer's liability is called upon, the employer bears the tax burden without recourse.

In practice, this means the dry income problem is solved only in cooperative employer-employee relationships. In adversarial terminations (bad leaver scenarios), the problem persists in full. Properly drafted leaver provisions in the participation agreement become essential.

3. Konzernklausel: open interpretation questions

The JStG 2024 group company clause raises unresolved questions. GAIA Law identifies a temporal ambiguity: if a group company was acquired rather than founded, does the 20-year founding requirement apply to the original founding date of the acquired entity? For mature companies joining a startup group through acquisition, this could disqualify the entire group.

Noerr flags a structural ambiguity: Section 19a(1) requires that the participation be transferred by "the employer or a shareholder of the employer." In complex group structures with intermediate holding companies, it is unclear whether a transfer from a great-grandparent entity qualifies. The BMF letter predates the Konzernklausel and provides no guidance.

Analysis

Section 19a EStG after the ZuFinG represents meaningful progress. The legislature correctly identified the dry income problem as a barrier to startup equity compensation and designed a targeted deferral mechanism with reasonable eligibility thresholds.

Three structural judgments emerge from the analysis.

First, the social insurance gap is a genuine deficiency, not just a theoretical concern. Any employer implementing Section 19a for employees below the contribution ceiling should budget for the immediate social insurance cost and communicate it clearly. The gap is not a reason to avoid Section 19a, but it undermines the narrative that the dry income problem is "solved."

Second, the dependency on employer cooperation in Section 19a(4a) reflects a deeper design tension. The provision was created to benefit employees, but its most powerful feature (indefinite deferral until exit) requires the employer to accept an irrevocable, open-ended contingent liability. Sophisticated employers with legal counsel will structure this appropriately. Early-stage startups without advisors may not understand the implications, leaving employees exposed.

Third, the interaction between Section 19a (deferral of the initial benefit) and the BFH's VIII R 13/23 and VIII R 14/23 (capital income classification of ongoing returns) creates a genuinely favorable landscape for properly structured real equity. An employee who receives Genussrechte, benefits from Section 19a deferral on the grant, and receives ongoing distributions taxed at 25% under Section 20 EStG is in a materially better position than one holding VSOPs taxed at 45%. The tax differential justifies the structuring complexity.

Practical implications

The following comparison summarizes the current landscape:

The practical recommendation depends on the company's resources and risk tolerance. For well-advised startups seeking to maximize employee benefit, direct equity or Genussrechte combined with Section 19a and an Abs. 4a employer liability election offer the best tax outcome. For startups prioritizing simplicity and speed, the VSOP remains pragmatically defensible despite its tax disadvantage. Genussrechte occupy the middle ground: real economic participation with favorable tax treatment, without the cap table complexity of direct equity.

Outlook

The ZuFinG II was effectively absorbed into the Standortfördergesetz (StoFöG), passed by the Bundesrat on 27 March 2026. The StoFöG does not contain further changes to Section 19a. This suggests the legislature considers the current framework adequate for now.

Three developments merit monitoring. First, the social insurance treatment of Section 19a participations may be addressed in future guidance or legislation. The current asymmetry between income tax deferral and immediate social insurance liability is widely acknowledged in practice. Second, the European Commission's EU Inc. proposal includes a standardized EU-ESOP framework that would tax employee equity only on actual sale, potentially making the dry income problem obsolete for companies using the new European form. Third, the BMF has yet to issue guidance on the Konzernklausel introduced by JStG 2024. A clarifying letter is expected in 2026 or 2027.

Conclusion

Section 19a EStG after the ZuFinG is a meaningful reform that gives German startups a tool to offer real equity to employees without immediate tax consequences. The deferral mechanism works. The employer liability option in Section 19a(4a) is well-designed for cooperative relationships. The 2024 Konzernklausel closes an important structural gap.

But the provision is not a complete solution. The social insurance gap, the dependency on employer cooperation, and the unresolved Konzernklausel interpretation questions mean that competent structuring and legal advice remain essential. The strongest configuration under current law is a real participation (direct equity or Genussrechte), combined with Section 19a deferral, an Abs. 4a employer liability election, and contractual protections for termination scenarios.

For founders weighing their options: the tax advantage of real equity under Section 19a (25% capital gains rate) over VSOPs (45% income tax rate) is substantial enough to justify the additional structuring effort. The BFH's January 2026 decisions further strengthen this position. The direction of German law is clear. The implementation details require care.
