What you really delegate when you outsource payroll in Switzerland, what remains the employer's responsibility, and which model suits which profile.
Reading time: 18 min
The managing director of an SME in the canton of Vaud signs a payroll outsourcing contract and considers the matter settled. A few months later, the compensation fund writes to the director, not to the provider.
Outsourcing payroll does not mean outsourcing the employer. What goes to a provider is an administrative workload: calculations, statements, declarations, deadlines to meet. What stays with you is the decision and the responsibility.
This article shows where that line runs: what the term "HR outsourcing" covers on the Swiss market, what can be delegated function by function, what can never be delegated, and which model fits which situation.
In brief
- Check what the word outsourcing covers in the proposal you are reading: payroll management alone, personnel administration as a whole, or the employment relationship itself.
- Do not expect to delegate your status as employer along with the statements: the law names the one who hires, not the one who calculates.
- Choose your model on the only question that truly separates the four: who remains the employee's employer.
- Set a monthly cut-off date and a single point of contact before the first payroll run, because it is this calendar, not the contract, that keeps the arrangement working day to day.
Payroll, HR administration, social insurance: what the word covers
Three people can use the word "outsourcing" in front of you and mean three different things. The first is thinking of the monthly salary calculation. The second adds contracts and personnel files. The third hands the employment itself to a third party. Nothing requires a proposal to cover all three. It is by reading it that you spot which of these scopes is being sold to you, and it is the only way to compare two offers.
Separate these blocks before comparing, or you risk paying for a task you will keep doing yourself. The reasons for delegating are covered in our article on the benefits of outsourcing payroll management. This page answers the next question: what exactly goes into the contract.
Payroll management
This is the easiest scope to pin down, the one fiduciaries also call payroll accounting: monthly calculation, issuing payslips, payment orders, periodic statements to the funds and annual declarations.
The process relies on data you pass on and produces dated documents. A fifteen-person consulting firm in Geneva that delegates this block keeps its organization intact.
Personnel administration
The second circle groups everything that surrounds the payslip without being a calculation: contracts and amendments, certificates, record keeping, permit monitoring, time and absence management, notifications of hires and departures.
This block often weighs more than payroll in hours worked. An architecture firm in Sion with twelve employees spends several days a month on it.
Social insurance management
The third block covers relations with the funds and insurers: affiliation with a compensation fund for AVS, AI, APG and AC, occupational pension (LPP) files, accident reports to your LAA insurer, notifications of hires and departures, follow-up of daily benefits.
It is the most technical of the three, because a single long-term absence involves the loss-of-earnings insurer, the compensation fund and your pension institution all at once.
What falls outside the scope: recruitment and HR development
The word "HR" suggests that human resources management can be delegated in full. In the offers on the Swiss payroll market, sourcing candidates, interviews, appraisals, training and everything to do with company culture remain outside the contract.
No one will recruit your workshop manager in Delémont for you. Read the list of services through this filter: administrative or human.
What can really be delegated
Read any offer in two columns: what is produced for you, and what is expected from you as input. The second column is missing almost everywhere, and it is the one that determines the workload you will be left with.
Filing deadlines and their calendar are detailed in the employer obligations checklist, which serves as the compliance reference; here we stick to the division of tasks.
Payslips and the monthly calculation
Your provider calculates gross pay, applies the deductions, produces each employee's payslip and prepares the payment file. It handles pro rata calculations for hires and departures, the 13th salary and the month's variable items.
It can only subject to contributions what you tell it about. A loyalty bonus paid to a team leader, a long-service gift, an allocation of employee shares to a manager: these items form part of the determining salary, and therefore of the contribution base, and only you know they have been decided.

Declarations and statements to the funds
It also prepares the periodic statements for your compensation fund, the annual salary declaration, the statements for your accident insurer and your pension institution, as well as your employees' salary certificates.
You provide the up-to-date list of your affiliations, the corresponding contract numbers and immediate notice of any change. A change of pension institution reported two months late produces two months of statements to redo.
Withholding tax and its cantonal rate tables
An employee's attachment to a canton is not assigned, it follows from their situation. What belongs to you is holding the information that determines it and answering for it; your provider then applies the rate table published by the competent tax authority. We do not publish any here, since they differ from one canton to another and are updated regularly.
You alone receive this information: place of work, type of permit, family situation, spouse's employment, a move. A cross-border sales advisor who moves to Switzerland changes situation that very month.
Contracts, amendments and certificates
An HR administration offer covers drafting contracts based on your decisions, amendments when an activity rate or a role changes, and routine certificates: a salary certificate for a bank, an interim reference, a certificate for unemployment insurance.
The decision remains yours, the drafting is theirs. This division holds as long as decisions arrive in writing: a raise announced verbally produces neither an amendment nor a line on the payslip.
Tracking time, absences and accidents
Time entry, vacation tracking, absence monitoring and reporting to insurers can be delegated, usually with an entry tool made available to your teams. Your partner sends reminders, checks consistency and calculates the balances.
The event itself happens at your end. An accident on a Friday evening on a building site in Fribourg has to be passed on before it can be reported.
Employee hires and departures
Hiring and departure formalities make up the most time-consuming batch: notifications to the funds, pension affiliation, opening the file, then the final settlement, deregistrations and leaving documents. These formalities follow one another in sequence at a provider, provided it receives in time what triggers them.
For that it needs the exact date, the signed contract and the reason for leaving. A resignation passed on three weeks late costs a correction across two payslips.
What can never be delegated
Part of the work changes hands, another part never changes owner. The distinction is not a commercial one: a service company carries out, you decide and you answer for it. This is the point proposals detail the least.
The decision to hire and dismiss
Hiring, promoting, setting pay, terminating a contract: these decisions belong to you, and no service contract transfers them. Your provider prepares the documents that put them into effect, calculates the final balance and produces the certificates.
The division shows in the sequence: you decide, you notify, it carries out. A restaurant manager in Montreux who asks the provider whether they can dismiss someone is asking the wrong person.
Your authority to direct your employees
Day-to-day instructions, objectives, organizing working hours, approving leave and appraising performance stay within your organization. An administrative mandate covers files, not people.
This point is not theoretical: it is what separates the four models described below.
The employer's responsibility toward social insurance
Your provider calculates and declares. The law, for its part, never names it: it names the employer. Employers must withhold the employee's contribution from all salary, settle the contribution account periodically with the compensation fund, and prepare the data needed to keep the employees' individual accounts. Withholding takes place at each payroll, and payment is made periodically by the employer, together with the employer's contribution.

The consequence appears a few articles further on and is worth reading word for word: "An employer who, intentionally or through gross negligence, fails to observe regulations and thereby causes damage to the insurance is liable to make good that damage." Where the employer is a legal entity, the members of its board and all persons involved in its management or liquidation are liable for the damage on a subsidiary basis.

A note from the Federal Social Insurance Office confirms the rule from the other end. Devoted to neighboring arrangements, it places outside its subject the offer that is limited to taking on administrative tasks, as a fiduciary, for clients who are self-employed as well as employers, and it states: "Such a service has no effect on their social security status." In other words, handing over the administrative processing does not shift the status of the one who handed it over.

We do not comment on the scope of these texts, which is assessed case by case and is a matter for the authorities and your legal counsel.
The information only you hold
The last point is a practical one, and it explains most of the errors found after outsourcing. No process can catch information that never reached it. A change of address, a birth that opens entitlement to family allowances, a renewed permit, an overtime hour approved on a building site: none of it reaches your provider unless someone at your end has passed it on.
The collective labor agreement (CLA) that applies to your sector or your company is part of this. Your provider calculates according to the minimum wages and rules it sets, but it does not know the agreement exists, or that it has changed, unless you tell it. A CLA declared generally binding, for example in the Geneva construction sector, applies automatically to every employer within its scope, whether or not they belong to a signatory association. Your provider, however, will only apply it if you tell it that you fall under it.
Delegating therefore shifts your workload toward collecting and checking. You stop calculating, you start feeding and verifying.
Four delegation models, four company profiles
The payroll and human resources outsourcing offers on the Swiss market fall into four models. They differ less in price than in their answer to a single question: who is the employee's employer once the contract is signed.
Outsourced payroll management
Your employees remain your employees, your contracts remain your contracts, and only the monthly processing goes out. It is the easiest model to undo, since it touches neither employment nor organization.
It suits companies that have an HR function, even if it comes down to one person, and that want to free up that person's time. A transport company in Neuchâtel with forty employees finds what it needs here.
Full HR administration
The scope extends to all personnel administration: contracts, amendments, certificates, time, absences, hires and departures. You keep the decisions and the authority to direct, and you hand over their administrative translation.
This model suits Swiss businesses without an HR department, where payroll is handled by the managing director or by accounting. It requires a designated point of contact at your end, without which information circulates poorly.
Personnel leasing
Here, the employment relationship splits in two, and the Federal Social Insurance Office describes what the market calls "payrolling". The arrangement involves two companies. Yours needs a skill without wanting to carry the employment contract; a second company hires the person and puts them at your disposal. You give the day-to-day instructions; it takes on the employer's functions, namely paying the salary, settling and paying social insurance contributions and, for a foreign employee, registering with the tax and migration authorities. The Office draws a clear conclusion: "Such an arrangement must be regarded as personnel leasing."

The model is regulated: "Employers (leasing companies) whose business is to hire out the services of workers to third parties (hiring companies) must have obtained a license from the cantonal employment office."
Source: Swiss Confederation, Federal Act on Employment Services and the Hiring of Services (LSE), RS 823.11, art. 12 para. 1, as at 1 January 2026, verified on 13 August 2026.
Asking to see that license is therefore the first reflex when faced with such a proposal. The model serves time-limited assignments: six months of reinforcement on an IT project in Basel.
Good to know
Two limits frame cross-border situations. A SECO license is required on top of the cantonal license to hire out the services of workers abroad, and hiring out staff from abroad into Switzerland is not permitted: the leasing company must be based in Switzerland. A foreign company that wants to place its own staff with a Swiss client therefore runs up against the text.

The employer of record
In this last model, the employment contract is carried on your behalf: the salary is paid, contributions are declared to the funds and the administration is kept up, while the person works for you. It meets a specific situation, that of a company with no legal entity in Switzerland that wants to employ one or two people there.
Depending on how the assignment is organized, this model can fall under the same licensing framework as personnel leasing: check this point before signing. Our page dedicated to the employer of record in Switzerland describes this arrangement.
What changes in your organization
Delegating creates work before it removes any: the first three months take up time for the person who runs payroll.
The management mandate, and what it should provide for
The contract that binds you to a payroll management company is often called a management mandate. What you check when reading it is what it lists:
- the exact scope of services, function by function, with what remains your responsibility;
- the mutual deadlines: your cut-off date for passing on data, its date for delivering the payslips;
- the transmission channel, the processing of your employees' personal data and where it is hosted;
- the designated contact on each side, and their deputy;
- the procedure in case of error: who corrects, within what time, on which payslip;
- the end of the relationship: notice period, return of data, handover of the annual cumulative totals.
That last point is negotiated at the start: a provider that agrees to put in writing how it will return your data is already showing its method.
The monthly transmission calendar
The real constraint of the arrangement is not the contract, it is a date. Each month, a cut-off sets the limit beyond which information no longer makes it into the current payroll. Whatever arrives later waits for the following month, with the corrections that implies.
Three rules are enough to keep this process on track: a single person passes on the data, a single channel is used, and your team leaders know the cut-off date. Salary data is most often transmitted to the funds and insurers using the Swissdec standard, which our page on payroll software in Switzerland or outsourcing covers in detail.
Taking over the history: the first three months
A switch during the year means taking over the cumulative totals already reached: contributions, pension bases, withholding tax already deducted, vacation and overtime balances. The salary certificate covers the whole year, however many parties have followed one another.
Plan for a full export from your current system, a parallel run on the first month to check the results line by line, and the availability of the person who knows the special cases. A horticultural business in Valais that switches in September without its cumulative totals finds out when the salary certificates are due.
The moments when the question arises
The question does not arise at a given headcount, and no text sets a threshold. It arises at identifiable moments, which recur from one company to the next:
- the first employee you hire, with an affiliation to a compensation fund to open before the first salary payment;
- employees spread across several cantons, which multiplies the attachments to monitor;
- the arrival of cross-border workers or foreign employees, with the permits and tax attachments that come with them;
- the departure of the person who ran payroll, when the know-how leaves all at once;
- growth that makes the monthly close heavier than the business itself.
None of these signals makes delegation mandatory. Each one justifies asking the question, because it changes the nature of the work, not just its volume.
Our offers follow the same dividing line: who remains the employee's employer. The Payroll Management Solutions cover the calculation, the payslips and the declarations without touching your employees' employment contracts, and you remain their employer. Personnel Leasing answers the other case, where the contract is carried by a third party, with the cantonal license this requires. Our payroll and HR specialists work from Switzerland and together have more than 50 years of cumulative experience in payroll management; the details of our services are on the Payroll Management Solutions page from Numeriq Payroll. Once the scope is set, it remains to choose who to entrust it to: our article on how to choose a payroll company in Switzerland is devoted to that.
Frequently asked questions
How do you outsource your payroll?
The process comes down to four steps. You define the scope function by function, separating what is produced for you from what you pass on. You choose the model, based on who remains the employer. You sign a contract that sets the mutual deadlines, data processing and exit conditions. Finally, you organize the takeover of the history and the monthly cut-off date.
What does payroll outsourcing cost?
There is no official rate, and the price depends on the scope, the headcount and the number of special situations. We therefore do not publish any amount here. Our dedicated article on the cost of payroll management in Switzerland sets out the pricing models.
Can I outsource only part of my payroll?
Yes. The combinations you come across are the monthly calculation alone, the calculation with the declarations to the funds, or processing only the employees subject to withholding tax. The limit lies in data consistency: two systems that each hold part of the workforce must be reconciled at the annual close.
Who is responsible if a contribution is not declared?
The law names the employer, not whoever carries out the work on its behalf. When an intentional failure to comply or gross negligence causes damage to the insurance, the employer must make good the damage. If the employer is a legal entity, the members of its board and the persons involved in its management or liquidation are liable on a subsidiary basis. The scope of this rule is assessed case by case, with your legal counsel and your fund.

How do you outsource the HR function when you have no HR department?
This is the most common situation in Swiss SMEs, where payroll is handled by the managing director or by accounting. Start by listing what is done today, including the invisible tasks: certificates, notifications to the funds, permit monitoring. Then designate a contact person, even part time, because the human resources function needs someone who decides and passes things on. The full HR administration model, described above, fits this case.
