Outsourcing payroll in Switzerland: process and costs

Payroll is one of the most sensitive tasks in a small or medium company. It leaves no room for error, it runs to fixed deadlines, and it touches the one thing every employee expects from you: the right salary, on time, in their account. Owners and managing directors therefore ask whether outsourcing pays off. This guide explains in plain English what Swiss payroll actually covers, how outsourcing works in practice, and what it realistically costs.

What payroll actually covers

The breadth of the task surprises most people. Payroll reaches well beyond transferring an amount of money. It means calculating every salary-related item correctly and reporting it to your employees and to the Swiss authorities.

The core elements:

• The monthly payroll run: gross to net salary, with every deduction, allowance, expense claim and variable component such as bonuses or hourly pay.
• Social insurance: correct calculation and settlement of AHV (the Swiss state old-age pension), IV (disability insurance), EO (compensation for loss of earnings during military service and parental leave), ALV (unemployment insurance), the occupational pension and accident insurance.
• Withholding tax (Quellensteuer): deducted at source from the salaries of employees who are subject to it, calculated monthly and paid over to the canton.
• Family allowances: child and education allowances, settled through the AHV compensation office.
• Salary certificates and confirmations: at year end and whenever an employee or an authority asks for one.
• Year-end work: reconciliation, final statements and the electronic declarations to every office involved.

Each of these items carries its own rules, its own deadlines and its own recipients. That variety is what makes payroll error-prone when it is squeezed in alongside other work.

Social insurance at a glance

Social insurance contributions sit at the heart of every Swiss payslip. A large share of them is split evenly between employer and employee, a principle known in Switzerland as parity.

The key figures for 2026:

• AHV, IV and EO together come to 10.6% of salary. The employee carries half of that, 5.3%, which the employer deducts from the salary and pays to the compensation office together with the employer share.
• Unemployment insurance (ALV) comes to 2.2% and is split in half in the same way. It applies to salary up to a ceiling of CHF 148'200 per year.
• The occupational pension (BVG), Switzerland's second pillar, becomes mandatory from an annual salary of CHF 22'680. The coordination deduction stands at CHF 26'460. That is the slice of salary the state pension already covers, so it comes off before the insured BVG salary is worked out. The exact savings contributions depend on age and on the rules of the chosen pension fund.
• Accident insurance (UVG) covers occupational and non-occupational accidents. The employer pays the premium for occupational accidents, and the employee usually carries the premium for non-occupational accidents.
• Family allowances are paid out through the compensation office and financed by an employer contribution.

Round a figure too generously, transpose two digits or overlook a salary ceiling, and the result is back payments, corrections and unhappy employees. A well-run external payroll service takes these calculations off your desk and delivers them accurately and on time.

Withholding tax: the tricky part

Withholding tax applies to employees who work in Switzerland without a C permit, the Swiss permanent residence permit, along with certain people resident abroad such as cross-border commuters. These employees file no Swiss tax return of their own. The employer deducts the tax directly from the salary and forwards it.

That sounds straightforward. Day to day, the employer has to:

• apply the correct tariff code for each family situation,
• calculate the tax monthly and precisely,
• pay it over to the canton responsible and file the return,
• and report changes promptly, for example a marriage, the birth of a child or a change in contracted hours.

Tariffs differ from canton to canton. Errors often surface late, and correcting them at that stage is slow and expensive. For companies with international teams, withholding tax ranks among the main reasons to outsource payroll. If you are still building your Swiss employer setup, our guide to hiring in Switzerland walks through the registrations that come first.

swissdec and the unified salary declaration procedure

Employers once had to enter the same salary data into a whole series of separate forms: once for the compensation office, once for the accident insurer, once for the statistics office. That meant duplicated work with plenty of room for error.

swissdec, the body that sets Swiss payroll standards, created Lohnstandard-CH, the national salary standard, and with it ELM (Einheitliches Lohnmeldeverfahren), the unified salary declaration procedure. The idea is simple and it works well: you record the salary data once in certified payroll software. From there it goes out electronically and encrypted to each authorised recipient.

Recipients of the data include:

• the AHV compensation office,
• the accident insurer and the daily sickness benefits insurer (Krankentaggeld, the cover that keeps salary flowing during a long illness),
• the withholding tax authorities,
• the Federal Statistical Office.

The standard keeps evolving. For withholding tax, ELM 5.0 has been mandatory since the 2026 salary year. The specific product version matters, not just the product name. Before electronic filing, we compare that version with the official Swissdec list. If it is not currently certified there, the system is updated or a suitable product is selected first.

How outsourcing works in practice

Outsourcing payroll hands the day-to-day execution to specialists while you keep oversight and the final say. The process usually follows a clear structure.

One-off: the setup phase

At the start, your master data moves across: employees, salaries, employment levels (Pensum, the contractual share of a full-time role), insurance arrangements and the payroll records to date. This phase matters because it lays the foundation for every payroll run that follows. A good provider also checks that everything recorded so far is correct.

Monthly: the payroll run

Each month you send the changes, for example new joiners, leavers, timesheets, bonuses or expenses. The provider runs the calculation, produces the payslips, prepares the payments and handles the declarations. You release the payments, so the money stays under your control.

Annually: the year-end work

At year end, the salary certificates are issued, the final statements with the social insurers are prepared and all declarations go out through swissdec. Each employee receives their salary certificate for the tax return.

One point deserves emphasis. A reliable partner takes the operational work off your hands in full. In the eyes of the authorities you remain the employer, and the legal responsibility stays with you. That is why reliability weighs as heavily as the price.

What does outsourcing payroll cost?

The honest answer: it depends. You have every right to transparency all the same. Costs are driven mainly by the number of employees, the complexity of the salaries and the range of additional services.

Typical cost drivers:

• the number of payslips per month,
• whether hourly wages, shift work or many variable items are involved,
• the share of employees subject to withholding tax,
• extra tasks such as change notifications, confirmations or reports.

Many providers bill per payslip, often in the range of CHF 20 to 100, depending on complexity and region. A monthly base fee and separate charges for the year-end work are common on top. Costs become hard to predict when items sit outside the published figure.

Our payroll price is published: CHF 250 per month plus CHF 25 to 40 per employee, depending on the complexity of your operation. We agree the figure with you before the engagement starts and it stays fixed. You know in advance what you pay. The full picture is on our pricing page.

If you need support beyond payroll itself, with contracts, reference letters or onboarding, our HR administration covers it: CHF 250 per month plus CHF 25 to 55 per employee on a subscription, and CHF 140 per hour for individual assignments. Combining payroll and administration earns a bundle discount of 7.5%. Our services page gives an overview of everything we handle.

Is outsourcing worth it for your company?

Do the maths honestly. Running payroll in-house costs money for software, takes real time and ties the knowledge to one or two individuals. When they are away, the payroll run stops. There is risk on top of that: a single withholding tax error or a missed deadline can become expensive.

Outsourcing pays off especially when:

• you have no HR function of your own or your HR team is stretched,
• payroll depends on a single person,
• you employ people subject to withholding tax or coming from abroad,
• you want your time to go into the core business,
• data security and clean data protection matter to you.
