10 min read What are your employer obligations for the salary certificate?
The answer is unambiguous: producing the salary certificate for each employee is a legal obligation of the employer, not an optional service. It stems from article 127 of the Federal Act on Direct Federal Taxation (LIFD) and from article 45 of the Act on the Harmonisation of Direct Taxes (LHID). The employee, on the other hand, fills in nothing: they receive, check and transfer.
A document owed spontaneously, every year
You must provide the certificate spontaneously, at the start of the year for the previous calendar year, usually in January or February, and this even if the employee does not request it. If the employee leaves during the year, it is produced at the end of the employment relationship. The official template (Form 11) and the completion rules are set by the completion guide published jointly by the Swiss Tax Conference (CSI) and the Federal Tax Administration (AFC), under reference 605.040, in its version valid as at 1 January 2026.
Your liability in the event of an error
An inaccurate or incomplete certificate is not neutral. The tax administration can require a correction, claim a withholding tax back-payment and, in the event of a breach of procedural obligations, issue a fine within the meaning of article 174 LIFD. The ibani team observes above all an underestimated side effect: an error blocks the employee's tax return abroad and quickly turns into an internal HR dispute. It is therefore better to secure the process upstream.

How do you correctly fill in sections 1 to 15?
The short answer: the certificate is structured into sections numbered 1 to 15, from the base salary (section 1) through to the free-form remarks (section 15), via the total gross salary (section 8) and the net salary (section 11). Each item has a precise definition; it is the rigour of your data entry that determines the acceptance of the document by the foreign tax authority.
Here is the completion table for the main sections of Form 11.
| Section | Heading | What the employer must enter |
|---|---|---|
| 1 | Salary | The base salary, including 13th month and paid overtime. |
| 2 | Fringe salary benefits | Benefits in kind: board and lodging (2.1), company car (2.2), other benefits (2.3). |
| 3 | Non-periodic benefits | Bonuses, gratuities and premiums paid irregularly. |
| 7 | Other benefits | Elements of remuneration not falling under the previous sections. |
| 8 | Total gross salary | The sum of all the above, before social deductions. |
| 9 | AVS / AI / APG / AC / AANP contributions | Employee's share of the 1st pillar and unemployment insurance contributions, deducted from the gross. |
| 10 | Occupational pension (2nd pillar) | Ordinary LPP contributions (10.1) and any buy-backs (10.2). |
| 11 | Net salary | The gross salary minus the contributions in sections 9 and 10. This is the basis of calculation abroad. |
| 12 | Withholding tax | Amount of tax you have withheld and paid over (Geneva cross-border workers, for example). |
| 13 | Professional expenses | Actual travel and meal expenses (13.1), other actual expenses (13.2), flat rates (13.3). |
| 15 | Remarks | Useful notes: employment dates, coverage of transport, details on cross-border status. |
Boxes F and G, classic sources of error
Beyond the sections, the certificate includes tick boxes that have a direct tax impact for the employee. The two most frequently mis-filled are box F (the employer covers the home-to-work commute) and box G (meals or canteen at a reduced price). Ticked wrongly or forgotten, they distort the deductible professional expenses flat rate and trigger a correction.

What precautions for a cross-border or expat employee?
The answer depends on the canton of work and the employee's country of residence, but one principle remains: it is the accuracy of your certificate that allows the foreign tax authority to accept it without friction. Two tax regimes coexist depending on your canton.
| Situation | Cantons concerned | Employer's role |
|---|---|---|
| "1983 agreement" cross-border worker | Bern, Solothurn, Basel-City, Basel-Country, Vaud, Valais, Neuchâtel, Jura | No withholding tax if the employee provides the 2041-AS residence certificate; section 12 stays empty. The certificate serves as supporting evidence for the tax paid in France. |
| Withholding tax | Geneva (and situations outside the 1983 agreement) | You withhold the tax at source and enter it in section 12. The employee obtains a tax credit in France to avoid double taxation. |
What the employee will do with your certificate
An employee resident in France transfers the figures from your certificate onto the 2047-SUISSE calculation aid worksheet, which explicitly refers to the line numbers of the Swiss document, to determine their taxable net salary in euros. They then transfer it onto the 2047 and 2042 returns. The more precise your certificate (consistent withholding tax in section 12, clear notes in section 15), the fewer additional queries the French tax administration will send them.
The same principles apply to an expat who declares their income in Italy, Germany, Spain or Portugal: only the national forms change, the salary certificate remains the proof of income. For the pension dimension of your employees residing outside Switzerland, see our guide LPP and foreign workers: the employer's obligations.
How do you streamline your teams' cross-border payroll?
The short answer: by removing the loss on exchange between the CHF paid and the euro actually received by your employees. The salary is calculated and, in principle, paid in Swiss francs. But many cross-border workers wish to receive their pay in euros into their account of residence, and this is where traditional channels cut into the real amount via invisible exchange margins.
A worked example at the reference market rate of 0.921: for a net salary of 5,000 CHF, the company pays this sum to ibani, and the employee receives exactly 4,605 EUR into their account, with no margin taken along the way. Across a team of several cross-border workers, the cumulative saving compared with a standard bank exchange becomes a genuine HR and financial lever.
Pay the salary in CHF like a standard Swiss transfer: ibani converts it into euros at the real interbank market rate and credits it to the employee's account, with no SWIFT fees or hidden exchange margin. The employee receives the full conversion, which strengthens the appeal of your HR package.

Frequently Asked Questions
Who must produce the Swiss salary certificate and by when?
It is the Swiss employer who produces, signs and hands over the salary certificate (Form 11), never the employee. This is a legal obligation under article 127 LIFD. The document must be provided to the employee spontaneously at the start of the year for the previous calendar year, even without a request, usually in January or February. If the employee leaves during the year, it is produced at the end of the employment relationship. In several cantons, the employer also sends a copy directly to the cantonal tax administration.
How do you correctly fill in sections 1 to 15 of the salary certificate?
The certificate is structured into sections numbered 1 to 15: base salary (section 1), fringe benefits and benefits in kind (section 2), non-periodic benefits such as bonuses (section 3), total gross salary (section 8), social security contributions AVS/AI/APG/AC (section 9), occupational pension LPP (section 10), net salary (section 11), withholding tax (section 12), professional expenses (section 13) and remarks (section 15). The employer must follow guide 605.040 of the Swiss Tax Conference and correctly tick boxes F (home-to-work commute) and G (meals).
What does an employer risk if there is an error on the salary certificate?
An incomplete or inaccurate certificate exposes the employer to correction requests from the tax administration, to a withholding tax back-payment and, in the event of a breach of procedural obligations, to a fine within the meaning of article 174 LIFD. Beyond the legal risk, an error directly penalises the employee, whose foreign tax return will be blocked or rejected, creating an avoidable internal dispute.
How does the salary certificate help the cross-border employee's return to the foreign tax authority?
An employee resident in France transfers the figures from the Swiss salary certificate onto the 2047-SUISSE worksheet to determine their taxable net salary in euros, then onto the 2047 and 2042 returns. An accurate and complete certificate, with consistent withholding tax (section 12) and clear remarks in section 15, allows the foreign tax authority to accept it without additional queries. It is therefore in the employer's interest to fill it in with care.
Should the employer pay the salary in Swiss francs or in euros?
The salary is calculated and, in principle, paid in Swiss francs (CHF). However, many cross-border employees wish to receive their pay in euros into their account of residence. The company can pay the salary in CHF to a B2B fintech solution like ibani, which converts the funds into euros at the real market rate and credits them to the employee's account, with no hidden margin, which becomes an HR retention argument.
