Structuring founder equity: Vesting, cliffs, and Swiss tax implications

Equity structuring is one of the most consequential decisions founders make — and one of the most common sources of disputes when things don’t go as planned. Swiss law offers flexibility, but also traps for the uninformed.

The basics: Who gets what, and when

Most Swiss startups begin with a simple share split among founders. The problems emerge later: a co-founder leaves early, contributes less than expected, or the team grows and needs to allocate new equity.

Vesting solves this by making equity conditional on continued contribution over time.

How vesting works in Switzerland

Unlike the US, Switzerland has no standardized vesting framework. Founders must contractually create their own vesting mechanism. Common approaches:

Reverse vesting

All shares are issued upfront, but subject to a repurchase right (Rückkaufsrecht) that lapses over time. This is the most common approach for Swiss startups.

• Typical schedule: 4 years with a 1-year cliff
• Cliff: No vesting occurs in the first year; if a founder leaves before the cliff, all shares can be repurchased at nominal value
• Acceleration: Consider single-trigger (on acquisition) or double-trigger (acquisition + termination) acceleration

Conditional share grants

Shares are only transferred as they vest. Simpler contractually but creates ongoing notarial requirements for each transfer.

Tax implications

This is where Swiss founders often get surprised:

• Income tax: If shares are granted below fair market value, the discount is taxable as employment income (even between co-founders)
• Vesting events: Each vesting milestone can trigger a taxable event if the shares have appreciated
• Capital gains: Generally tax-free for individuals in Switzerland — but only for shares held as private assets, not as employment compensation

The Art. 17d approach

Structuring equity as “Mitarbeiteraktien” under the Federal Tax Administration’s circular allows deferred taxation under certain conditions. This requires careful planning at incorporation.

Common mistakes

1. No vesting agreement at all: The #1 mistake. If a co-founder walks after 6 months with 33% of the company, you have a problem
2. Vesting without a shareholders’ agreement: Vesting is one piece; drag-along, tag-along, pre-emption rights, and deadlock resolution are equally important
3. Ignoring tax on grant: Founders assume nominal value = fair market value. After a seed round, it usually doesn’t
4. US-style option pools without Swiss adaptation: ESOP structures from US templates often don’t translate cleanly to Swiss corporate law

Our recommendation

Get the equity structure right at incorporation — or at latest before your first external funding round. The cost of restructuring later (legally, tax-wise, and interpersonally) is disproportionately higher.
