What is a salary certificate?

A salary certificate is an official document that employers create once a year for employees. In addition to the wages, salaries and other remuneration that an employee has received over the course of a calendar year, it lists the social security contributions and any withholding taxes paid. The salary certificate is required for the tax return as detailed proof of income.

Swiss salary certificates: an overview of the most important provisions

According to the Swiss Tax Act (Art. 168 of the Steuergesetz) employers are obliged to issue their employees with a salary certificate for each past calendar year. As a rule, employees receive their salary certificates in January of the following year.

However, federal law does not provide for an exact deadline for issuing the salary certificate. Rather, this is determined by cantonal regulations or by the guidelines and recommendations of the cantonal tax administrations.

However, the form to be used is uniform throughout Switzerland. The Swiss Federal Tax Administration provides a downloadable PDF form of the salary certificate on its website.

Regulations and legal texts on Swiss salary certificates

In Switzerland, various laws and regulations regulate the proper creation and use of salary certificates. In particular, the following must be taken into account:

  • The Swiss Federal Act on Direct Federal Taxation (DBG): among other things, the DBG determines the components of the income and the deductions to be included in the salary certificate. Article 127 DBG establishes the obligation of third parties to provide certification, for example, the obligation of employers to account for the benefits they have paid to employees.
  • The Swiss Federal Act on the Harmonisation of Direct Taxes of the Cantons and Municipalities (StHG): the StHG creates a uniform basis for the cantonal tax laws and thus also has an influence on salary certificates.
  • Regulations and instructions of the Swiss Federal Tax Administration (FTA): the FTA regularly issues instructions and explanations that provide detailed information on how to correctly fill in the salary certificate.
  • Cantonal tax laws and regulations: since tax jurisdiction in Switzerland lies with both the federal government and the cantons, the cantons have their own tax laws, which may contain supplementary provisions on income taxation. These laws vary depending on the canton.
  • Social insurance laws: the deductions for social insurance, such as old-age and survivors' insurance (AHV), disability insurance (IV), loss of earnings compensation (EO) and unemployment insurance (ALV) must also be included in the salary certificate. These are regulated by laws such as the AHVG (Swiss Federal Act on Old-Age and Survivors' Insurance) and the AVIG (Swiss Federal Act on Compulsory Unemployment Insurance and Insolvency Compensation).
  • Swiss Withholding Tax Ordinance: if withholding taxes are deducted, these must also be noted in the salary certificate in accordance with the Swiss Withholding Tax Ordinance (QStV).

Particularly important: the salary certificate must be filled in correctly. Anyone who does not fill in a salary certificate or who fills it out incorrectly can be prosecuted (Articles 127, 174 and 186 DGB, Articles 43, 55 and 59 StHG and Article 251 StGB) and held liable (Article 177 DBG, Article 56 StHG). It is therefore worthwhile to manage your payroll accounting with software like bexio: it supports you in correct creating salary certificates and makes the process simple and understandable.

Salary certificate for employees: when and how is it submitted?

The salary certificate serves as the most important proof for the income tax return. Employees should therefore know when and how to forward this document after receiving it. The following tips should be borne in mind:

Timely receipt of the salary certificate in full

Employers should usually prepare and issue the salary certificate by the end of January of the following year. If an employer allows this period to pass, employees should point this out to them and ask for the salary certificate to be issued. If someone has been employed several times with different employers in the past calendar year, separate salary certificates are required from each of them.

Attachment to the income tax return

The employee submits the salary certificate together with the income tax return. The exact time for filing the tax return varies depending on the canton. In most cantons, the deadline is 31st March, but in some it can be between the end of February and the end of April. Be sure to find out about the requirements for your canton.

Form of submission

It is now possible to file the tax return electronically in all cantons. It is therefore sufficient to scan the salary certificate during its electronic or online creation and upload it as an attachment. There is no need to sign it in writing. For paper-based submissions, taxpayers send a copy of the salary certificate together with their other documents.


It is advisable to keep the original salary statement and all other relevant tax documents for at least five years in case there are questions or there is a tax audit, or should an employee become incapacitated for work. They will then be used to prove income.

Late submission

If you do not file the tax return on time, you may be reminded and, in certain circumstances, will receive a fine. On request, many cantons grant a deadline until September or December for filing the tax return. Here, again, you should find out about the requirements in your canton. It is also important to request any extension of the deadline in good time before the end of the actual deadline.

Filling out the salary certificate for employers: required information

The salary certificate consists of two sections: the upper part contains general information about the employee, their employment relationship and the reporting period for all data in alphabetically ordered sections A to H.

The lower part, in 15 numbered lines, records the employee's detailed benefits and deductions in the past calendar year. The gross wage is first determined in lines 1 to 8, and the net wage in lines 9 to 11, by amassing all deductions. Lines 12 to 15 serve to record further individual tax deductions, expense allowances, fringe benefits and additional remarks.

1. Wage

In addition to the ordinary salary, the daily benefits from health and accident insurance as well as all allowances (commissions, allowances for commuting to and from work and external catering at the place of work) must also be listed in line 1.

2. Fringe benefits

These include, for example, benefits in the form of meals and accommodation, or the private share in a company car, if provided. Here, 0.9 percent of the purchase price, excluding VAT, must be declared monthly (i.e., a maximum of 10.8 percent in a full calendar year).

3. Irregular benefits

Under this point, everything must be listed that cannot be attributed to the ordinary salary and regular fringe benefits, but is paid on a case-by-case basis, such as bonus payments, anniversary gifts, loyalty bonuses or relocation compensation.

4. Capital benefits

This means, on the one hand, back pay of wages and, on the other hand, severance payments and capital benefits of a provisioning nature.

5. Participation rights

These are shares and options in the company held by employees.

6. Compensation paid to the board of directors

Separate from the regular and irregular benefits, the compensation paid to the board of directors or attendance fees and royalties must be listed here.

7. Other benefits

Point 7 includes, among other things, various proportionate contributions made by the employer to insurance for employees, as well as benefits from unemployment insurance (ALV) and loss of earnings compensation (EO), contributions to occupational pension institutions, daily benefits from insurance companies that are not declared under point 1, and school fees for children. In addition, if they make up a substantial part of the salary, tips.

8. Total gross salary

In this line, all previously listed amounts/benefits are added. The sum makes the total gross salary for the past calendar year.

9. Contributions to AHV, IV, EO, ALV and NBUV

In line 9, the contributions for old-age and survivor's insurance (AHV), disability insurance (IV), loss of earnings compensation (EO), unemployment insurance (ALV) and non-occupational accident insurance (NBUV) are recorded.

10. Occupational pension

In this section, all deductions for the ordinary contributions to the occupational pension plan as well as the contributions for buying into the occupational pension plan must be entered.

11. Total net salary

The deductions from the gross salary listed under points 9 and 10 result in the net salary. This is essential for the tax return and must be carried over into it.

12 to 15. Further information

Lines 12 to 14 record any possible withholding taxes, expense allowances and other fringe benefits (such as goods and services received at a preferential price).

Under "Remarks" in line 15, again, any further information that does not fit under any of the preceding points must be noted. This may include, for example, notes stating that the employee in question has several salary certificates, or that the position in question is a part-time position. The number of days with loss of earnings compensation and any agreed employee participations or relocation costs paid by the employee themselves are also listed here.

Finally, the employer confirms the place, date and correctness of the information in field I.

Creating a salary statement: employers have these options

As an employer, you have three options for creating a salary certificate.

1. Download and fill out the form

First, download the official salary certificate form from the Swiss Federal Tax Administration. To be able to view and edit it, you need either Adobe Acrobat Reader or Snapform Viewer. Both pieces of software are free of charge, and the FTA also provides download links on its website.

Once you have created the salary certificate and entered all the data correctly, you can print it out and hand it over to the employee in duplicate (one for passing on with their tax return, one for their own records).

2. Use eLohnausweis SSK – the electronic salary certificate

The electronic salary certificate from the Swiss Tax Conference (SSK) is a free web application that SMEs, for example, can use without any dedicated salary software. The number of salary certificates to be created with this software is unlimited.

Important: eLohnausweis SSK is not cloud software. This means that all necessary wage information must be stored correctly and is the sole responsibility of the software users. Unsaved data may be lost and must be entered again in eLohnausweis SSK (this is due to data protection requirements).

There is a form view and a guided mode with additional assistance. Electronic transmission of salary certificates to the cantonal tax administrations by means of Lohnstandard-CH from Swissdec (ELM) is not supported.

The Swiss Tax Conference provides a helpful collection of FAQs on eLohnausweis SSK. In addition, you will find the current Guidelines for Completing Salary Certificates and overviews of the cantonal tax authorities on the information page of the Swiss Federal Tax Administration.
