Why equity plans are central to Swiss startups
For many startups and SMEs structured as GmbHs, human capital matters more than paid-in capital. When cash budgets are tight, equity participation plans — stock options, restricted shares, or virtual participation — allow you to align employees' interests with those of the founding shareholders, deferring compensation until an exit or a concrete increase in company value.
In Switzerland, however, an equity plan is not a simple internal document: it affects taxable remuneration, OASI/BVG contributions, withholding tax, the balance sheet, and — in the case of GmbHs — the transferability of membership interests. The difference between a well-structured option and an informal agreement can translate into thousands of francs in back taxes, social security penalties, or unforeseen balance sheet liabilities.
This guide explains how to choose the legal form of the plan, which tax and accounting obligations to activate, and how to document each stage — from grant to vesting, from exercise to transfer — with reference to current federal law and the practices most widely used among Swiss scale-up GmbHs and AGs.
Types of plans: which instrument for which objective
Before drafting regulations or amending the articles of association, it is worth clarifying which instrument fits the company's profile and the level of risk accepted by employees and investors:
| Instrument | Mechanism | Best suited to | Typical tax treatment |
|---|---|---|---|
| Share / membership interest options | Right to purchase at a preset price (strike) after a vesting period | Growing startups, tech teams, imminent investment round | Income from gainful activity at exercise (Art. 17b para. 3 DBG) |
| Restricted shares / membership interests | Actual transfer with a contractual prohibition on transfer for a defined period | Key people, management, companies with stable valuations | Taxability on acquisition with a 6% discount per year of restriction, up to a maximum of ten years (Art. 17b paras. 1 and 2 DBG) |
| Virtual participation (phantom shares) | Right to a cash payment linked to share value performance, without transfer of securities | GmbHs with restrictive approval clauses, operational teams without company membership | Income from gainful activity at payment (Art. 17c DBG) |
| Direct grant of unrestricted shares / membership interests | Immediate transfer without transfer restrictions | Exceptional cases, one-off bonuses already settled for tax purposes | Immediate taxability at market value on the acquisition date |
| Convertible / SAFE for employees | Convertible risk capital instrument converting into membership interests or shares at future events | Pre-seed startups with professional investors | Case-by-case assessment; often income at conversion |
For GmbHs, virtual participation is often the quickest solution: it avoids the actual transfer of membership interests and the associated formalities (shareholders' meeting approval, entry in the register of membership interests and the Commercial Register). For AGs — the preferred form when raising capital from funds or planning an IPO — options on registered shares remain the de facto market standard.
Legal and corporate setup: GmbH vs AG
An effective equity plan requires consistency between the articles of association, plan regulations, employment contract, and — for GmbHs — any shareholders' agreements:
GmbH — registered membership interests
Every transfer of membership interests to an employee requires a written transfer agreement (Art. 785 CO) and, as a rule, approval by the shareholders' meeting (Art. 786 CO), unless the articles of association provide otherwise. The articles must provide for or authorize the plan; in the absence of a permissive statutory clause, shareholders' meeting approval is required for individual transfers.
Many GmbH startups create a class B membership interests (full economic rights, limited voting rights) reserved for the team, or use an intermediate holding vehicle. The pool of interests allocated to the plan must be stated explicitly in the cap table and, if necessary, protected by a dilution clause in investor agreements.
AG — shares and authorized capital reserve
The AG may issue participation shares (Art. 656 CO) with different rights and establish a conditional capital reserve for the plan. The board of directors, if delegated by the articles of association or the general meeting, may increase share capital within authorized limits without convening the general meeting each time.
Option plan regulations must precisely define the maximum number of shares, the exercise price, vesting conditions, good leaver / bad leaver provisions, and valuation methods in the absence of a liquid market.
Mandatory elements of the plan regulations
- •Eligible beneficiaries (employees, consultants, board members with an employment relationship)
- •Pool size (typically 10–20% of fully diluted capital for startups)
- •Vesting schedule (12-month cliff and linear vesting over 3–4 years is the standard)
- •Fair market value valuation method (latest round, simplified DCF, contractual formula)
- •Exit provisions: acceleration on exit, forfeiture in case of early voluntary resignation
- •Tax and social security reporting obligations borne by the beneficiary
Taxation: employee, company, and withholding tax
Tax treatment depends on the type of instrument and the point at which the beneficiary acquires an effective economic benefit. The distinction between restricted shares and unrestricted instruments is decisive:
| Event | Options / virtual participation | Restricted shares / membership interests (Art. 17b DBG) |
|---|---|---|
| Grant | No immediate taxability for unlisted or not freely tradable options (taxation at exercise, Art. 17b para. 3 DBG); for phantom shares, taxability at payment (Art. 17c DBG) | Taxability on acquisition: fair market value minus a 6% discount per year of restriction (max. 10 years) minus purchase price |
| Exercise / vesting | Taxable income = fair market value at exercise minus price paid | As a rule, no new taxable event arises during the restriction period; early release generates additional income (Art. 11 OPart) |
| Transfer / exit | Capital gain = difference between sale price and taxable value already taxed at exercise | Gain on sale generally treated as private capital gain exempt from tax (Art. 16 para. 3 DBG), subject to taxable components under FTA Circular No. 37 |
| Tax rate level | Federal, cantonal, and municipal income tax + possible withholding tax | Same treatment as employment income; no automatic relief at federal level |
Requirements for tax-recognized restriction (Art. 17b para. 2 DBG and FTA Circular No. 37): the transfer restriction must be set out in a written contract or plan regulations; the employee may not freely dispose of the security (sell, pledge, or encumber) during the restriction period. There is no statutory minimum duration: the 6% discount applies for each year of contractual restriction, up to a maximum of ten years. If the requirements are not met, the FTA taxes the benefit as salary on the acquisition date without any discount.
Withholding tax: for employees subject to withholding tax (generally without a C permit or with cross-border commuter status), the benefit from option exercise is subject to withholding tax at the ordinary rate on income from gainful activity. The paying company must calculate the taxable base, withhold the tax, and include the amount on the salary certificate.
Company side: the benefit granted to the employee is generally deductible from the company's taxable income as personnel expense, provided it is documented and granted on arm's-length terms. For virtual participation, provisioning a liability when the entitlement vests is tax-relevant.
Accounting under Swiss standards
SMEs applying Swiss accounting standards (Swiss GAAP FER) must reflect equity plans so that the balance sheet faithfully represents the obligation to beneficiaries. For share-based payments, established practice follows FER 31 principles and professional recommendations:
Options and virtual participation
For equity-settled options, if fair value is determinable at grant, personnel expenses are recognized on a straight-line basis over the vesting period, with a corresponding entry in equity reserves. For virtual participation (cash-settled), a liability for employee benefits is provisioned equal to fair value, remeasured at each closing date until payment.
Typical entries: debit Personnel expenses — equity plans (account 6xxx) / credit Equity reserves (options) or Liabilities for employee benefits (account 23xx, phantom shares). At exercise or cash payment, the liability or reserve is settled and any difference between the amount recorded and the amount paid affects the current period.
Restricted shares / membership interests
If shares are granted at a price below fair market value, the difference constitutes personnel expense generally recognized on acquisition (or allocated over the restriction period, depending on the accounting policy adopted).
The actual transfer of membership interests or shares changes equity: increase in nominal capital (if applicable) and/or recognition of share premium in reserves. For GmbHs, verify that the capital increase meets formal requirements and that the contribution is recorded in the register of membership interests.
| Stage | Accounting entry | Practical note |
|---|---|---|
| Grant with vesting | Monthly accrual of fair value / number of vesting months | Document the valuation method (simplified Black-Scholes or latest round value) |
| Forfeiture (early departure) | Reversal of unvested liability or reserve | Recognition in income statement of cost no longer owed |
| Option exercise | Settlement of reserve/liability + recording of strike payment in capital/cash | Share issuance or membership interest transfer with written contract and shareholders' meeting approval (GmbH) |
| Phantom share payment | Debit personnel expense / credit cash or liability | Include the amount on the salary certificate for OASI and withholding tax |
Companies adopting IFRS or US GAAP apply IFRS 2 / ASC 718 with stricter fair value measurement criteria. If the FER balance sheet is the basis for the tax return, aligning the two approaches with your tax advisor avoids discrepancies between accounting income and taxable income.
OASI, BVG, and unemployment insurance
Every benefit that qualifies as taxable remuneration triggers mandatory social security contributions. The obligation arises when the benefit is determinable and taxable — not necessarily at grant:
- 1OASI/IV/EO: the salary base includes income from option exercise and payments from virtual participation. For restricted shares, contributions accrue when the income becomes taxable (generally on acquisition of the interests), unless cantonal practice differs.
- 2BVG (2nd pillar): if the taxable amount exceeds the coordinated threshold, check whether the fund regulations provide for contributions on extraordinary salary elements. Many funds require an additional one-off contribution borne by the employer and the employee.
- 3UI (unemployment insurance): the taxable benefit counts toward the benefit base. Undervaluation at exercise can result in a retroactive adjustment by the cantonal compensation fund.
Caution: cashless exercise and employee financing
When the company finances option exercise (cashless exercise) or advances withholding tax, the entire net amount paid to the employee constitutes taxable salary. Planning the necessary liquidity — especially ahead of an exit — avoids cash flow strain and social security disputes.
Operational checklist for GmbHs and startups
Before communicating the plan to the team, verify that every administrative step is covered:
Independent or documented valuation
Fair market value determined using a traceable method (latest round, appraisal, statutory formula). Essential for options and to avoid tax assessments.
Shareholder / general meeting approval
Formal resolution on pool creation, plan regulations, and — for GmbHs — authorization to transfer membership interests to employees.
Individualized grant letter
Number of options/interests, strike price, vesting schedule, leaver clauses, and reference to the general plan regulations.
Integration into the salary certificate
Include the taxable benefit on the annual certificate (Form 11 or equivalent) and manage withholding tax where applicable.
Accounting entries and updated cap table
Monthly accruals, register of membership interests or share register, dilution table shared with investors and auditor.
Employee disclosure
Written explanation of personal tax and social security consequences, with a recommendation to consult a tax advisor for the cantonal tax return.
Common mistakes to avoid
Verbal promises without documentation
An informal agreement on "1% of the company" without a strike price, vesting, or valuation creates civil disputes and tax risks. Formalize before hiring.
Confusing legal restriction and statutory restriction
A transfer restriction provided only in internal regulations, but not formalized contractually, does not activate the Art. 17b para. 2 DBG discount. The employee may be taxed immediately on the full market value at acquisition.
Forgetting the impact on the investors' cap table
A 15% pool not diluted before Series A can block a round. Negotiate the ESOP (Employee Stock Option Plan) in the term sheet from the outset.
Treating phantom shares as non-salary income
Cash payments from virtual participation are always income from gainful activity. Omitting them from the salary certificate exposes you to OASI penalties and tax assessments.
Transferring GmbH membership interests without formalities
Transferring membership interests to an employee at exercise requires a written contract, shareholders' meeting approval (unless the articles provide otherwise), and entry in the register of membership interests. Omitting these steps invalidates the transfer and complicates a future exit.
With Accountex: keep costs, liabilities, and deadlines under control
A well-designed equity participation plan is a strategic tool; poorly managed, it becomes a hidden balance sheet liability and a tax risk for the company and employees. The key is to integrate the accounting perspective from the outset — periodic accruals, cap table updates, salary certificates — with the legal and tax perspective.
With Accountex you can record personnel expense accruals, monitor liabilities for employee benefits, link phantom share payments to cash flows, and prepare data for the salary certificate and year-end close. For GmbHs and scaling startups, having up-to-date figures on the real cost of the equity plan also facilitates investor negotiations and compliance with OASI and cantonal tax deadlines.
