Payslip Dematerialization in Switzerland

In Brief

• Electronic payslips are accepted in Switzerland. Article 323b of the Code of Obligations (CO) requires a salary statement, not a paper document.
• The condition is practical: the employee must be able to access, read, save and print the payslip at any time.
• To our knowledge, no Swiss provision requires the employee’s consent, but informing staff and offering a transition period is recommended.
• Under the revised Federal Act on Data Protection (FADP), in force since September 1, 2023, delivery must be secured: encryption, restricted access and breach notification.
• Employers keep payroll records for 10 years (art. 958f CO), and electronic archiving is possible.
• French rules (right to refuse, 50-year retention) do not apply by default to work performed in Switzerland.

 

Yes, Swiss law allows electronic payslips. Article 323b CO requires the employer to hand over a salary statement, and nothing in it demands paper, provided the employee can access, read, save and print the document. Most French-language information online describes French law, which does not apply by default to work performed in Switzerland. This guide sets out the Swiss legal framework, data protection duties, retention rules, costs and a six-step method for moving to paperless payroll.

 

What Is Payslip Dematerialization?

 

Payslip dematerialization means producing, delivering and archiving payslips in digital form instead of on paper. In practice, it covers three levels: a PDF sent by e-mail, secure delivery through encrypted messaging, and an employee portal or app that also stores the archive. Each level offers a different balance of security, cost and employee experience.

In Switzerland, the standard term for the document is the salary statement, and the same idea appears under several names. The sections below use these terms consistently so that readers can match them to their own tools. For the content of the document itself, see our guide to the Swiss payslip.

 

Electronic payslip, PDF, portal: what are we talking about?

 

• Electronic payslip: any payslip delivered in digital form, whatever the channel.
• PDF payslip: a file generated by the payroll system, sent by e-mail or made available for download.
• Employee portal or app: a secure online space where each employee logs in to view, download and archive payslips and, often, other HR documents.
• Digital safe: a long-term storage service attached to the portal, designed to keep documents unaltered.

 

What does dematerialization not cover? The salary certificate and Swissdec

 

Two documents are often confused with the payslip. The electronic wage declaration known as Swissdec ELM transmits data from payroll software to insurers and authorities. It is not a way to deliver payslips to employees. The salary certificate is an annual document for tax purposes and follows its own rules. For example, some cantons such as Vaud do not accept certificates sent as PDF attachments by e-mail and require transmission through certified payroll software.

 

Is the Electronic Payslip Legal in Switzerland?

 

Yes. In Swiss law, article 323b CO requires the employer to give the employee a salary statement, and the law does not prescribe paper. Swiss practice and legal commentary accept electronic delivery, provided the employee can access, read, save and print the payslip at any time. The Canton of Zurich confirmed in 2023 that no legal change was needed to deliver payslips electronically.

 

Article 323b CO: a statement, not necessarily on paper

 

The French text of article 323b CO states that a statement is handed to the employee (« un décompte est remis au travailleur »). The German version speaks of a written statement (« schriftliche Abrechnung »). In practice, a document that the employee can read, store and print fulfills this function, which is why electronic delivery is accepted. The law gives no list of mandatory items, but the statement must allow the employee to check the calculation.

Do employers need the employee’s consent?

 

To our knowledge, no Swiss provision requires the employee’s consent or grants a general right to a paper copy. This differs from French law. Good practice is nevertheless to inform employees in advance, offer a transition period and keep paper available on request for employees without digital access. Check the employment contract, internal regulations and any collective labor agreement, since these may contain specific rules. For a specific case, validate the position with a lawyer.

 

Is an electronic signature required?

 

No. The payslip is not a document subject to written form, so no signature is needed. A qualified electronic signature (art. 14 para. 2bis CO) is only necessary where the law requires a handwritten signature. It can still help to prove the integrity of archived files.

 

Switzerland or France: Do Different Rules Apply to Cross-Border Workers?

 

Yes. Swiss and French rules differ on the legal basis, the default channel, the right to refuse and employee retention. The table below summarizes the contrast so that cross-border workers and French readers do not apply the wrong rules.

 

 

What does French law say?

 

For contrast only: French law makes electronic delivery the default, requires the employer to notify employees, and lets each employee object at any time. French rules also require the employee to keep access to the payslips for 50 years or until the age set in the Labor Code plus 6 years. These rules come from the French Labor Code and the official public service information.

 

Which law applies to a cross-border worker employed in Switzerland?

 

As a rule, the law of the country where the work is habitually performed applies (art. 121 of the Federal Act on Private International Law), unless the contract validly chooses another law. French rules on electronic payslips therefore do not apply by default to a French resident working in Geneva. Consider an employer with 80 employees, 20 of them French cross-border workers: the same Swiss approach applies to all 80. For specific contracts, seek legal validation. For payroll specifics, see our article on cross-border worker payroll.

 

How Do You Secure Payslip Delivery and Protect Data?

 

You secure payslip delivery by choosing a channel that matches the sensitivity of the data. A payslip contains personal data and sometimes sensitive information, such as health-related absences. The revised FADP requires security appropriate to the risk, so an unencrypted PDF sent by regular e-mail is not recommended.

 

Employer obligations: art. 328b CO and the FADP

 

• Article 328b CO: the employer may process only data related to the employment relationship.
• FADP article 8: technical and organizational measures must ensure security appropriate to the risk, for example encryption and restricted access.
• FADP article 24: a data breach likely to result in a high risk must be reported to the Federal Data Protection and Information Commissioner as soon as possible. There is no fixed 72-hour rule.
• Fines of up to CHF 250,000 can be imposed, and they target the responsible individuals rather than the company.

For a deeper look at these duties, read our article on payroll data protection in Switzerland.

 

E-mail, protected PDF, secure messaging, portal: which channel should you use?

 

 

Hosting in Switzerland or abroad: points to check

 

Transfers of personal data abroad are regulated by the FADP. Since September 15, 2024, the Swiss-US Data Privacy Framework allows transfers to certified US companies only. When evaluating a provider, ask where data is hosted, how it is encrypted, who keeps access logs and which subcontractors are involved.

 

How Long Must Payslips Be Retained and Archived Electronically?

 

Employers must keep payslips for 10 years, because payroll records form part of the accounting records (art. 958f CO). Electronic archiving is allowed if the files stay unaltered and traceable. Employees have no legal retention duty, but keeping payslips for at least 5 years is advisable because salary claims expire after 5 years (art. 128 CO).

 

Employer: 10 years and unalterable files

 

The Ordinance on the Keeping and Retention of Accounting Records requires integrity and traceability, and the PDF/A format is recommended for long-term storage. Files must remain readable throughout the retention period, so the archive should be tested periodically. For the broader legal context, see our article on payroll documentation obligations.

 

Employee leaving the company: what happens to the payslips?

 

Portal access usually ends with the employment relationship. Employers should therefore plan a final export, or a send-out of all payslips, in their offboarding process. A typical case is an employee who asks for three years of payslips after leaving to support a mortgage application. Employees should download their documents before the last working day.

 

What Do Electronic Payslips Really Cost and Change?

 

The benefits are real but depend on the channel. Electronic delivery can reduce printing and postage, speed up distribution, make payslips available at any time and simplify archiving. The limits are channel fees, change management and employees without digital access. Payslips are one part of the wider digital transformation of payroll.

 

The real cost of a paper payslip

 

The national postal operator charges CHF 1.20 for a standard A-Post letter and CHF 1.00 for B-Post in 2026. From January 1, 2027, the prices rise to CHF 1.40 and CHF 1.10. This is only the postage.

 

Illustrative calculation (example, not a benchmark)

• 100 employees x 13 payslips x CHF 1.10 (B-Post, 2027) = CHF 1,430 of postage per year.
• To add: printing, envelopes and the handling time of the payroll team.
• To subtract: the cost of the electronic channel, which varies from a few cents per message to a platform fee.

 

Savings depend on the channel: the cases of Zurich and Basel-Land

 

Two Swiss public-sector examples show why the business case needs a case-by-case review. In 2012, the Canton of Zurich rejected electronic delivery for cost reasons: secure e-mail would have cost CHF 0.46 per message for about 37,000 payslips per month. In 2023, the Zurich government found that no legal change was needed to deliver payslips electronically. In 2016, Basel-Land estimated that secure e-mail would cost about CHF 50,000 per year, similar to the postage savings. The takeaway is that the channel drives the business case.

 

How Do You Roll Out Electronic Payslips in Six Steps?

 

You roll out electronic payslips by following six steps, from the audit to the offboarding procedure:

1. Audit: review the current process, employment contracts, internal rules and any collective labor agreement.
2. Choose the channel: compare protected PDF, secure messaging and employee portal using the table above.
3. Check data protection: confirm hosting location, access rights and the breach notification procedure.
4. Inform employees: announce the change, define a transition period and keep paper on request.
5. Run a pilot: start with one team, collect feedback and fix issues before the full rollout.
6. Set up archiving and offboarding: define the 10-year archive and the final export when employees leave.

 

Outsourcing payroll and payslip delivery

 

Employers without in-house expertise can outsource both payroll and delivery. A specialized provider can run paperless payroll processing and offer digital document management through an employee portal, as part of outsourcing payroll with an employee portal. When comparing providers, ask about the delivery channel, hosting location and access rules after an employee leaves.

 

Going further: the digital personnel file

 

The same principles apply to the digital personnel file, a frequent next step after payslips. Article 328b CO still limits the data to what relates to the employment relationship, employees keep their access rights, and retention after departure must be planned. Digitizing absence management and time tracking is a logical follow-up once payslips are paperless.

 

Frequently Asked Questions About Electronic Payslips

 

Can my employer impose the electronic payslip?

 

Swiss law does not require the employee’s consent, as far as current sources show, provided the payslip remains accessible, readable, savable and printable. Check your contract, internal rules and any collective labor agreement. Many employers keep paper on request during a transition.

 

Can a payslip be sent by unencrypted e-mail?

 

It is not recommended. A payslip contains personal and sometimes sensitive data, and the FADP requires security appropriate to the risk. Use at least a password-protected PDF, and ideally secure messaging or an employee portal.

 

What happens to my electronic payslips if I leave the company?

 

Portal access usually ends with the employment. Ask for an export of all your payslips before leaving. Employers should plan this step in their offboarding process.

 

Does a PDF payslip have the same value as a paper payslip?

 

Yes, it fulfills the same function of salary statement under article 323b CO. For banks or landlords, a PDF generated by the payroll system is generally used like a paper copy.

 

Can the salary certificate also be sent by e-mail?

 

To the employee, electronic delivery is possible. To the tax office, cantonal rules apply. For example, Vaud does not accept PDF files sent by e-mail and requires transmission through certified payroll software.

 

Is a qualified electronic signature required on the payslip?

 

No. The payslip is not subject to written form. A qualified electronic signature is only needed where the law requires a handwritten signature, although it can be useful to prove the integrity of archives.

 

How much does it cost to send a paper payslip?

 

Postage alone is CHF 1.00 (B-Post) to CHF 1.20 (A-Post) in 2026 and CHF 1.10 to CHF 1.40 from 2027, before printing, envelopes and handling. For 100 employees and 13 payslips a year, B-Post postage alone reaches about CHF 1,430 in 2027.

 

Conclusion

 

Electronic payslips are legal in Switzerland, and a good rollout rests on three things: a channel that protects personal data, a 10-year archive, and a clear transition for employees. Start with an audit and a pilot, and plan the offboarding export from day one.
