Base Salary and 13th Month

The base salary (Grundgehalt) is the fixed contractual amount. Most Swiss employers add a 13th month salary equal to one additional monthly salary (1/12 of annual compensation, typically paid in November or December, or split into two half-months). The 13th month is not legally mandatory (OR does not require it), but it is standard practice and required by many GAV (construction, hospitality, banking). It is subject to AHV, ALV and income tax. Once established as a consistent practice, the employer cannot unilaterally remove it without a contract change.

Variable Compensation

Many Swiss employers offer variable components: individual bonus (discretionary, tied to personal performance), team or company bonus (tied to collective targets), profit-sharing (Tantième), or long-term incentives (stock options, restricted stock units, more common in listed companies). Unless contractually guaranteed, bonuses are discretionary and can be reduced or eliminated. A promise of a certain bonus in a job offer letter can create a legitimate expectation, even without formal contract inclusion.

Fringe Benefits and Total Compensation

Typical fringe benefits in Swiss employment: company car (private share 0.9% of purchase price/month, taxable), public transport allowance (GA), health insurance contribution (employer voluntary), pension fund contributions above the BVG minimum, childcare subsidy, staff restaurant/meal vouchers, phone/computer. Fringe benefits that have monetary value must appear on the Lohnausweis (wage certificate). Compare total compensation including benefits, a lower base with full health insurance and company car can be more valuable than a higher bare salary.


Frequently Asked Questions

Is the 13th month salary mandatory in Switzerland?

Not by federal law. However, it is mandatory under many GAV (collective agreements). If established as consistent practice over multiple years, it becomes an implied contractual obligation that the employer cannot remove unilaterally.

Is a bonus guaranteed if promised during the hiring process?

A written promise in the offer letter can create an expectation. Pure discretionary bonuses with no formula can be reduced to zero. Bonuses tied to measurable targets (revenue, profitability) are harder to deny if targets are met. Always push for clarity in writing.

What fringe benefits are tax-free in Switzerland?

Reimbursement of actual business expenses is tax-free (up to amounts in the approved expense policy). Contributions to BVG above legal minimum: deductible for the employee. Health insurance employer contributions: partially taxable. Company gym, canteen discounts within limits: often not taxed.
