Employer Registration Switzerland: AHV & VAT (2026)
Before hiring the first employee in Switzerland, a company must complete employer registration with several authorities. Failure to register correctly results in retroactive liability for unpaid social insurance contributions, interest at 5% per annum, and penalties. This guide covers every mandatory registration step — AHV, accident insurance, occupational pension, sickness benefits, source tax, and VAT — with timelines and contribution rates for 2026.
Step 1: AHV Compensation Office Registration (Ausgleichskasse)
The first and most important employer registration in Switzerland is with the cantonal AHV compensation office (Ausgleichskasse). This is the central hub for Swiss social insurance — AHV (old age insurance), IV (disability insurance), EO (income compensation for military service and maternity), and in most cantons, FAK (family allowances).
How to register: Apply to the cantonal Ausgleichskasse in the canton where the company is registered. In Zug, this is the Ausgleichskasse Zug. The application requires:
- Commercial Register extract of the company
- Details of directors and any initial employees
- Expected annual payroll
Timeline: Registration typically completed within 1–2 weeks.
What you receive: An employer number and account with the Ausgleichskasse. Going forward, you submit monthly or quarterly AHV declarations and pay contributions on that schedule.
Contribution rates (2026):
- AHV/IV/EO: 10.6% of gross salary (employer pays 5.3%, employee pays 5.3%)
- ALV (unemployment insurance): 2.2% up to CHF 148,200 annual salary (employer 1.1%, employee 1.1%); 1% solidarity surcharge above CHF 148,200
- FAK (family allowances): cantonal; employer pays approximately 1.5–3.5% of payroll (rate depends on canton)
The Federal Social Insurance Office (FSIO) publishes AHV contribution rates and thresholds at admin.ch.
Step 2: Accident Insurance (UVG / SUVA)
Swiss employers must insure employees against occupational accidents and occupational disease under the Federal Accident Insurance Act (UVG/LAA).
Occupational accident insurance (Berufsunfall): Mandatory from the first day of employment. The employer pays 100% of the premium. Most employers are automatically affiliated with SUVA (Schweizerische Unfallversicherungsanstalt) for certain industries; others can choose a private accident insurer.
Non-occupational accident insurance (Nichtberufsunfall): Required for employees working 8 or more hours per week with the employer. The employee pays the premium, deducted from salary.
Registration: Contact SUVA or your chosen private insurer before the first employee starts. SUVA will issue an employer policy number.
Step 3: Pension Fund (BVG / 2nd Pillar)
Swiss employers must affiliate with an occupational pension fund (Pensionskasse) for all employees earning above the BVG entry threshold (CHF 22,680 per year in 2026).
Employer obligation: Pay at least 50% of the BVG contributions. The employee pays the remaining portion, deducted from salary. Total contribution rates are age-dependent, rising from approximately 7% (age 25–34) to 18% (age 55–65) of the BVG-coordinated salary.
How to affiliate: Either join an industry-specific collective pension fund or establish a connection with an independent Pensionskasse. Many banks and insurance companies offer BVG collective foundations (Sammelstiftungen) for SMEs.
Timeline: Must be in place before the first BVG-eligible employee starts. Allow 2–4 weeks.
Step 4: Daily Sickness Benefit Insurance (Krankentaggeld)
Not legally mandatory under statute, but treated as essential in practice — most collective labour agreements (GAV) impose it, and Swiss employment market norms expect it.
Typical Krankentaggeld coverage: 80% of salary from day 30 of illness, for up to 720 days (2 years). Employer and employee typically share the premium equally.
Register with a health insurer offering group Krankentaggeld insurance before the first employee starts.
Step 5: Source Tax Registration (Quellensteuer) for Foreign Employees
If you hire foreign employees who do not hold a Swiss C permit and are not married to a Swiss citizen, you must withhold income tax at source (Quellensteuer) from their salary and remit it to the cantonal tax authority monthly.
Registration: Apply to the cantonal tax authority (Steueramt) in the canton of the company’s domicile. In Zug, this is the Steuerverwaltung Zug.
Rate: Depends on gross salary, civil status, number of dependent children, and canton. Monthly rates are published by each cantonal authority in Quellensteuer tables.
Swiss nationals and C-permit holders file ordinary tax returns — no employer withholding is required beyond social insurance.
For employees who require a work permit in Switzerland — such as B permit holders — source tax withholding is required from the start of employment. See our B permit guide for permit classes and their tax treatment.
Step 6: VAT Registration
VAT registration is separate from employer registration and is required when the company’s annual turnover from taxable supplies exceeds CHF 100,000. Registration is with the ESTV (Federal Tax Administration) and is voluntary below the threshold.
For new companies expecting to exceed CHF 100,000 in turnover in the first year, voluntary early registration is advisable — it allows input VAT recovery from the start. Registration takes 2–4 weeks.
The ESTV provides VAT registration forms and guidance on estv.admin.ch. For a full breakdown of Swiss VAT rates and rules, see our VAT Switzerland guide.

Ongoing Employer Obligations
Once registered, an employer’s recurring obligations include:
- Monthly/quarterly AHV declarations and payments to the Ausgleichskasse
- Monthly source tax remittance for foreign employees
- Annual payroll reconciliation (Lohnausweis — salary certificates to each employee and cantonal tax authority by 31 January)
- BVG contribution payments (monthly or as agreed with the Pensionskasse)
- Quarterly or monthly VAT returns (depending on the method selected)
- Annual AHV audit by the Ausgleichskasse (typically every 4 years for small employers)

Frequently Asked Questions
When must employer registrations be completed relative to the start of employment?
All registrations should be in place before the first employee starts work. AHV and accident insurance (UVG) are particularly time-sensitive — retroactive contributions with interest at 5% per annum apply if registration is delayed.
Does a sole director/owner count as an employee for these purposes?
If the director receives a salary, they are an employee for AHV and social insurance purposes. Even a sole shareholder-director who pays themselves a salary must be registered as an employee with the Ausgleichskasse. A director who takes only dividends (no salary) may not need to be registered — but this arrangement has tax implications that should be reviewed.
What happens if we miss the AHV registration?
The Ausgleichskasse will assess retroactive contributions from the date employment commenced, with interest at 5% per annum on unpaid amounts. In addition, employer-paid contributions that should have been withheld from employees cannot be recovered retroactively — the employer bears both halves.
What are the AHV contribution rates in Switzerland in 2026?
AHV/IV/EO combined rate is 10.6% of gross salary (employer 5.3%, employee 5.3%). ALV (unemployment insurance) is 2.2% on salaries up to CHF 148,200 — employer pays 1.1%, employee pays 1.1%. A 1% solidarity surcharge applies on salaries above CHF 148,200. FAK (family allowances) is cantonal, approximately 1.5–3.5% of payroll, paid entirely by the employer.
Is Krankentaggeld (daily sickness benefit) insurance mandatory in Switzerland?
Krankentaggeld is not a statutory requirement under federal law, but most collective labour agreements (GAV) impose it, and Swiss employment market norms treat it as standard. In practice, virtually all employers covering a workforce of any size maintain group Krankentaggeld insurance. The typical benefit is 80% of salary from day 30 of illness for up to 720 days.
What is the BVG entry threshold for occupational pension in 2026?
The BVG entry threshold is CHF 22,680 per year in 2026. Employees earning below this amount are not subject to mandatory BVG affiliation, though voluntary coverage is possible. Above the entry threshold, the employer must pay at least 50% of the applicable BVG contributions.
Who must register for source tax (Quellensteuer) withholding?
Employers must register for Quellensteuer withholding if they hire foreign employees who do not hold a Swiss C permit and are not married to a Swiss citizen. This includes B permit holders, L permit holders, and most other non-C-permit foreign nationals. Swiss nationals and C-permit holders file ordinary tax returns independently — the employer has no additional withholding obligation beyond social insurance.
When is VAT registration required for a new employer in Switzerland?
VAT registration with the ESTV is required once annual taxable turnover exceeds CHF 100,000. Voluntary registration below this threshold is permitted and is advisable if the business will incur significant input VAT from the start. Registration takes approximately 2–4 weeks from submission of the application.
How often must an employer file AHV declarations?
AHV declarations and payments are made monthly or quarterly to the cantonal Ausgleichskasse, depending on payroll size. An annual payroll reconciliation (Lohnausweis) must be submitted to each employee and the cantonal tax authority by 31 January each year. The Ausgleichskasse conducts a formal AHV audit approximately every four years for small employers.
Can a foreign company register as an employer in Switzerland without a Swiss subsidiary?
A foreign company posting employees to Switzerland must comply with Swiss employer registration requirements, including AHV enrolment, under the Swiss posted workers rules (Entsendegesetz). For longer-term operations involving employees permanently based in Switzerland, establishing a Swiss subsidiary or branch office is generally required to satisfy Swiss employment law, tax, and social insurance obligations fully. See our company formation Switzerland guide for entity options.
