Swiss Salary Certificate: Common Errors, Controls and Best Practices

What is the purpose of the salary certificate?

The salary certificate is an essential official document in Swiss employment relations. Its main purpose is to declare the income received by an employee to tax authorities and social insurance agencies. This document is indispensable for:

• Tax declaration: Employees use the salary certificate to complete their tax returns.
• Social insurance: The declared amounts serve as the basis for calculating social contributions (AVS, AI, APG, etc.).
• Social benefits: Declared income affects eligibility for certain social benefits, such as family allowances or health insurance subsidies.
• Administrative procedures: The salary certificate may be required for credit applications, rental agreements, or other procedures needing proof of income.

In summary, this document ensures transparency of income and social charges for both employer and employee.

Taxable and non-taxable elements in the salary certificate

The salary certificate must accurately reflect taxable and non-taxable income. Here is a clear distinction between these two categories:

Taxable elements

• Gross salary: The total amount before deductions.
• Bonuses and premiums: Any additional remuneration, such as performance or year-end bonuses.
• Benefits in kind: For example, private use of a company car or employer-paid phone subscriptions.
• Meal and accommodation allowances: If they exceed the exempt amounts set by law.
• Overtime allowances: If not exempt according to legal conditions.

Non-taxable elements

• Family allowances: These amounts are not subject to tax.
• Reimbursement of professional expenses: Provided they are justified and comply with the guidelines of the Federal Tax Administration (FTA).
• Employer contributions to occupational pension schemes: For example, contributions to the 2nd pillar.
• Modest gifts: Gifts valued below CHF 500 are generally not taxable.
