AHV/AVS Contributions

What Are AHV/AVS Contributions?

 

In brief: AHV (Alters- und Hinterlassenenversicherung) and AVS (Assurance-vieillesse et survivants) are the German and French names for Switzerland’s first-pillar state insurance system. It covers old-age pensions, survivors’ benefits, disability insurance (IV), and income compensation (EO). Both employers and employees contribute equally at a combined rate of 12.10% of gross salary with no earnings ceiling as of 2024.

 

How AHV/AVS Contributions Work?

 

AHV/AVS is Switzerland’s mandatory state social insurance system, known as the first pillar of the Swiss three-pillar pension system. Every employee working in Switzerland and every employer with staff in Switzerland must contribute. The system is pay-as-you-go: today’s contributions fund today’s retirees, not the individual contributor’s own future pension.

The AHV/AVS umbrella actually covers three separate insurance schemes that are administered together and reported as a single contribution: AHV/AVS (old age and survivors insurance), IV/AI (disability insurance), and EO/APG (income compensation for military service, maternity, paternity, and adoption leave). These are always grouped together in payroll processing and remitted to the cantonal compensation office as one combined amount.

 

Who Must Contribute?

 

Every person who works in Switzerland must contribute to AHV/AVS, regardless of nationality or permit status. This includes Swiss citizens, foreign nationals with any permit type (L, B, C, or G), cross-border commuters, and part-time employees. There is no minimum hours threshold or minimum salary below which contributions can be avoided. Even an employee earning CHF 500 per month owes AHV/AVS contributions on that income.

Employers are jointly liable with employees for the full contribution. The employer deducts the employee’s share from gross pay and adds the employer’s matching share on top, then remits the combined total to the cantonal compensation office (Ausgleichskasse/caisse de compensation). If an employer fails to deduct and remit correctly, the compensation office holds the employer liable for both shares.

 

The Three Schemes Within AHV/AVS

 

AHV (old age and survivors insurance) is the largest component. It funds retirement pensions for individuals who have reached the reference age (65 for men and 65 for women since the AHV 21 reform took effect January 1, 2024, which harmonized the reference age) and survivor pensions for spouses and children of deceased contributors. The AHV pension is calculated based on the individual’s contribution history and average annual income over their working life.

IV (disability insurance) funds pensions, rehabilitation support, and integration measures for individuals who are unable to work due to disability. IV benefits are assessed based on the degree of disability and the individual’s ability to earn income through work.

EO (income compensation) funds replacement income during military service, civil service, civil protection service, maternity leave (14 weeks at 80% of insured income, capped at CHF 220 per day as of 2024), paternity leave (2 weeks at 80%, capped at CHF 220 per day), and adoption leave (2 weeks). The EO compensation is triggered by the employee and paid by the compensation office; the employer receives reimbursement and in turn pays the employee during leave.

 

The Cantonal Compensation Office

 

AHV/AVS is administered through cantonal compensation offices (Ausgleichskassen), not a single federal agency. Every employer registers with the compensation office of the canton in which the company’s registered office is located. The compensation office assigns an employer identification number, issues annual contribution rates, and receives the monthly remittances.

Some employers, particularly those affiliated with industry associations, may instead be registered with a professional compensation office (Verbandsausgleichskasse) specific to their industry. The contribution rates are the same; only the administrative body differs. Employers must register before their first employee starts work. The registration triggers a contribution assessment and the first monthly remittance obligation.

 

 

AHV/AVS Contribution Formulas and Rate Table

 

AHV/IV/EO contributions are straightforward in structure: a fixed percentage of gross salary, no earnings ceiling, equal split between employee and employer. The complexity lies in correctly defining the contribution base and maintaining accurate records for the annual salary declaration.

 

Contribution Formulas (2024 Rates)

 

• Formula 1: AHV/IV/EO Employee Contribution

AHV/IV/EO (Employee) = Gross Salary x 6.05%   (AHV 5.125% + IV 0.70% + EO 0.225%) No annual earnings ceiling. Applied to total gross pay including base salary, bonuses, 13th month payments, overtime pay, and taxable allowances. Does not apply to expense reimbursements that meet the conditions for expense deductibility. Example: CHF 10,833 gross x 6.05% = CHF 655.39 employee deduction per month.

• Formula 2: AHV/IV/EO Employer Contribution

AHV/IV/EO (Employer) = Gross Salary x 6.05% Exactly mirrors the employee contribution. No ceiling. The employer pays this on top of the gross salary as an additional employment cost; it is not deducted from the employee’s pay. Combined total employer and employee = 12.10% of gross. Example: CHF 10,833 x 6.05% = CHF 655.39 employer cost per month, same as employee.

• Formula 3: ALV Unemployment Insurance (bundled with AHV/AVS remittance)

ALV (Employee) = MIN(Annual Gross, CHF 148,200) x 1.10% / 12 ALV (Employer) = MIN(Annual Gross, CHF 148,200) x 1.10% / 12 ALV is remitted to the same cantonal compensation office as AHV/IV/EO. The annual cap of CHF 148,200 (CHF 12,350/month) applies. Contributions stop once the cap is reached year-to-date. Example (below cap): CHF 10,833 x 1.10% = CHF 119.17 per side per month.

• Formula 4: Monthly Remittance to Compensation Office

Monthly Remittance = (AHV/IV/EO Employee + AHV/IV/EO Employer + ALV Employee + ALV Employer) for all employees Sum the AHV/IV/EO and ALV contributions for every employee on the payroll for the month. The employer submits the total in one payment to the compensation office, typically by the 10th of the following month. The compensation office reconciles at year end against the annual salary declaration. Example (1 employee at CHF 10,833 gross): AHV/IV/EO CHF 655.39 x 2 + ALV CHF 119.17 x 2 = CHF 1,549.12 monthly remittance.

• Formula 5: Annual AHV Salary Declaration

AHV-Lohnbescheinigung Total = Sum of AHV-Relevant Gross Salary for Each Employee for the Full Calendar Year By January 30 of the following year, the employer submits an annual salary declaration listing every employee’s AHV-relevant gross income for the year. The compensation office reconciles monthly remittances against this total. Under-payment triggers a final invoice; over-payment triggers a refund. The annual declaration is also the basis for each employee’s individual AHV account entry, which determines their future pension entitlement.

Why AHV/AVS Matters for Swiss Employers?

 

AHV/IV/EO contributions are not an optional benefit. They are a statutory obligation that begins with the first day of employment and carries direct financial and legal consequences for non-compliance.

 

Employer Liability and Audit Risk

 

The cantonal compensation office conducts employer audits (Arbeitgeberkontrolle) to verify that AHV/IV/EO contributions have been correctly calculated and remitted. These audits cover the previous five years of payroll records. Common findings include: incorrect identification of AHV-relevant income (for example, excluding bonuses or 13th month payments from the contribution base); under-reporting of part-time or casual employee wages; and failure to register new employees before their first paycheck.

If an audit finds a shortfall, the compensation office assesses the back-contributions plus interest from the date the payment should have been made, and in cases of negligence, adds a surcharge. The interest rate on unpaid AHV/IV/EO is set annually; it has historically ranged between 3.5% and 5% per year. Employers who deliberately under-report can face criminal prosecution under the Federal Social Insurance Act.

 

Impact on Employee Pension Entitlements

 

Every CHF of AHV/IV/EO contribution is recorded on the individual’s AHV account held by the compensation office. This account drives the employee’s future pension entitlement. Missing or under-reported contributions reduce the employee’s future pension, creating both an ethical obligation on the employer and a potential basis for a civil claim by the employee if contributions were incorrectly withheld but not remitted.

Employees can request a free copy of their AHV individual account statement (Auszug aus dem individuellen Konto) at any time to verify that all contributions have been recorded. Payroll errors that led to under-reporting of income are visible in the account record and can surface years or decades after the payroll period in question.

 

Total Employment Cost Planning

 

The employer’s 6.05% AHV/IV/EO contribution plus the 1.10% ALV contribution represent a mandatory 7.15% cost on top of every franc of gross salary with no ceiling. For a Swiss company with 50 employees averaging CHF 9,000 per month, the combined monthly AHV/IV/EO and ALV employer cost is approximately CHF 32,175 (CHF 9,000 x 50 x 7.15%), or CHF 386,100 per year, before BVG, SUVA, and FAK obligations are added. Finance teams that exclude these costs from headcount budgets systematically underestimate total workforce cost.

 

AHV/AVS Compared to Social Insurance in Other Countries

 

Switzerland’s AHV/AVS system is distinctive in two ways: there is no annual earnings ceiling for AHV contributions (unlike the United States Social Security cap or Germany’s Beitragsbemessungsgrenze), and the contribution rate includes disability and income compensation within a single bundled rate rather than separate schemes.

 

Country	Equivalent Scheme	Combined Employer + Employee Rate	Annual Earnings Cap	Key Difference from AHV/AVS
Switzerland (AHV/IV/EO)	Old age, disability, income compensation	12.10% (6.05% each)	None	No cap; disability and EO included in one rate
Germany (RV + KV + AV + PV)	4-branch statutory social insurance	Approx. 40% combined (all branches)	Varying by branch (RV: EUR 90,600/year West, 2024)	4 separate schemes; health insurance included; each has own ceiling
United States (FICA)	Social Security (OASDI) + Medicare	15.30% combined (7.65% each)	SS: USD 168,600 (2024); Medicare: no cap	Separate caps by scheme; no disability in main FICA rate
France (retraite de base + complementaire)	State pension + mandatory supplementary	Approx. 27% combined (pension only)	Plafond de la Securite Sociale (PSS): EUR 46,368/year (2024)	Complex multi-bracket structure; far higher employer burden overall
United Kingdom (NICs)	National Insurance Contributions	25.8% combined (13.8% employer + 12% employee up to UEL)	Employee: Upper Earnings Limit GBP 50,270/year	No formal earnings cap for employer NICs; no dedicated disability fund
Singapore (CPF)	Central Provident Fund	37% combined (17% employer + 20% employee, under 55)	Ordinary Wage Cap: SGD 6,800/month (2024)	CPF funds retirement, healthcare, and housing; rate drops with age

The AHV/AVS combined rate of 12.10% (6.05% per side) appears lower than Germany’s or France’s combined social insurance burden. However, Switzerland has separate BVG pension contributions (second pillar) on top of AHV that add 7% to 18% of insured salary per side depending on employee age, making the true combined Swiss social insurance cost significantly higher than the AHV/AVS rate alone suggests.

 

AHV/AVS vs. BVG (2nd Pillar Occupational Pension)

 

AHV/AVS and BVG are the two mandatory pension-related contributions in Swiss payroll. They are frequently confused because both deduct from employee wages and fund retirement income. They are structurally very different.

Dimension	AHV/AVS (1st Pillar)	BVG/LPP (2nd Pillar)
Legal basis	Federal AHV Act (AHVG)	Federal Act on Occupational Retirement (BVG)
System type	Pay-as-you-go: contributions fund current retirees	Fully funded: individual savings account for each employee
Contribution rate	6.05% employee + 6.05% employer = 12.10% combined	Age-dependent: 7-18% per side; employer matches or exceeds employee
Earnings ceiling	None: applies to 100% of gross salary	Yes: BVG coordination deduction of CHF 25,725/year (2024); max insured salary CHF 88,200/year
Entry threshold	No minimum: all earnings subject to AHV/AVS	CHF 22,050 annual salary minimum (2024)
Administered by	Cantonal compensation office (Ausgleichskasse)	Employer-chosen pension fund (Pensionskasse)
Remittance recipient	Cantonal compensation office	Employer’s affiliated pension fund
Remittance frequency	Monthly (typically by 10th of following month)	Monthly or as fund specifies
Annual declaration	AHV salary declaration by January 30	BVG annual reconciliation to pension fund
Pension benefit	Defined benefit formula based on contribution years and average income	Capital accumulation converted to pension or paid as lump sum at retirement
Portability	Stays with the individual; continues across employers	Vested benefit transferred to new employer’s fund on job change; can be withdrawn tax-free only on permanent emigration or self-employment
Disability coverage	IV component of AHV covers basic disability	BVG covers disability at occupational level above AHV

Key employer takeaway: AHV/AVS and BVG are separate obligations remitted to different recipients on different schedules. Missing one does not affect the other. Both are mandatory and both generate independent audit risk from separate authorities. The compensation office audits AHV; the cantonal pension fund supervisory authority oversees BVG compliance.

 

Best Practices for AHV/AVS Compliance

 

Register With the Cantonal Compensation Office Before the First Hire

 

AHV registration must be completed before the first employee starts work. The compensation office assigns an employer number and sets up the contribution account. Registration retroactive to the first pay period is possible but triggers immediate back-contribution assessment. Contact the compensation office of the canton where your company’s registered address is located and allow at least two to three weeks for processing.

 

Include All AHV-Relevant Income in the Contribution Base

 

The AHV contribution base is broader than base salary. It includes: base salary, overtime pay, bonuses, commissions, 13th month salary, taxable allowances (housing, car, meals above the flat-rate deduction), and tips. It excludes: reimbursed business expenses documented per the expense regulations, family allowances paid under FAK, and benefits that qualify for exemption under the AHV income guidelines. Errors in defining the contribution base are the most common finding in compensation office audits.

 

Remit Monthly by the Compensation Office Deadline

 

Monthly AHV/IV/EO and ALV remittances are typically due by the 10th of the month following the pay period, though deadlines vary by compensation office and employer size. Set up automatic payment instructions to the compensation office’s bank account using the correct payment reference. Late remittances attract interest. Persistent late payment can result in the compensation office requiring the employer to pay a security deposit or switch to a more frequent remittance schedule.

 

Update the AHV Rate Each January

 

The AHV 21 reform changed contribution rates effective January 1, 2024. The Federal Social Insurance Office (FSIO) publishes rate updates each year. Implement the updated rates before the first January payroll run. Using prior-year rates in January creates under- or over-contributions across all employees for the entire year until corrected. Configure payroll systems to pull the current year’s rates from a centrally maintained rate table updated by a designated owner before each year’s first payroll.

 

Submit the Annual AHV Salary Declaration by January 30

 

The annual AHV salary declaration (AHV-Lohnbescheinigung) must be submitted to the cantonal compensation office by January 30 of the following year. It lists the AHV-relevant gross income for every employee who worked for the company during the calendar year, including those who left during the year. The compensation office reconciles this declaration against the monthly remittances. Discrepancies result in a final assessment or refund. The declaration also updates each employee’s individual AHV account, so accuracy directly affects employee pension entitlements.

 

How Applic8 Handles AHV/AVS Contributions?

 

Applic8 calculates AHV/IV/EO and ALV contributions for every Swiss employee through As1 using the current year’s statutory rates. When the Federal Social Insurance Office updates contribution rates each January, As1 applies the new rates centrally before the first payroll run of the year. No manual rate update is required from the employer’s payroll team.

The contribution base is calculated correctly for each employee, including base salary, 13th month accruals, bonuses, and taxable allowances. As1 distinguishes between AHV-relevant income and exempt items such as qualifying expense reimbursements, applying the correct treatment to each income component automatically.

Monthly remittance reports are generated for each employer’s registered compensation office in the required format, ready for submission and payment. The platform tracks each employee’s year-to-date AHV-relevant income and ALV contribution base, stopping ALV contributions automatically when the CHF 148,200 annual ceiling is reached.

The annual AHV salary declaration is generated as part of the year-end close workflow, listing every employee’s AHV-relevant gross income for the calendar year, formatted for direct submission to the cantonal compensation office by the January 30 deadline. All AHV/IV/EO calculations are fully logged with the gross income base, rate applied, and contribution amount for each pay period, providing the audit trail required for compensation office reviews.

 

 

Frequently Asked Questions About AHV/AVS Contributions

 

How are AHV/AVS contributions calculated?

 

AHV/IV/EO contributions are calculated at a combined rate of 12.10% of gross salary, split equally between employee (6.05%) and employer (6.05%), with no annual earnings ceiling. The 6.05% employee rate breaks down as: AHV 5.125%, IV 0.70%, and EO 0.225%. ALV unemployment insurance adds a further 1.10% per side on earnings up to CHF 148,200 per year (2024). The employer deducts the employee’s share from gross pay and remits both shares to the cantonal compensation office monthly. Example: CHF 10,833 gross x 6.05% = CHF 655.39 per side per month for AHV/IV/EO alone.

 

What is the difference between AHV/AVS and BVG?

 

AHV/AVS (first pillar) is a pay-as-you-go state scheme: today’s contributions fund current retirees, not the contributor’s own future pension. It applies to all Swiss earnings with no ceiling. BVG (second pillar, also called LPP in French) is a fully funded occupational pension: contributions accumulate in the individual employee’s personal pension account. BVG applies only to employees earning above CHF 22,050 annually (2024), and only on the insured salary after the BVG coordination deduction (CHF 25,725 in 2024). Both are mandatory. They are remitted to different recipients: AHV to the cantonal compensation office, BVG to the employer’s chosen pension fund.

 

Are AHV/AVS contributions the same for all employees in Switzerland?

 

The rate is the same for all employees subject to Swiss AHV: 6.05% employee, 6.05% employer, combined 12.10%, with no earnings ceiling. What differs is the contribution base. AHV applies to all gross employment income including bonuses, 13th month payments, and taxable allowances, but excludes qualifying expense reimbursements and certain exempted benefits. All employees working in Switzerland, regardless of nationality or permit type, must contribute. The only exception is self-employed individuals, who pay a different AHV rate on their business income. As1 applies the correct base and rate to every employee automatically.

 

When must AHV/AVS contributions be remitted?

 

Monthly remittances are typically due by the 10th of the month following the payroll period, though exact deadlines vary by cantonal compensation office and employer size. Small employers may be permitted quarterly remittance. Payment must be made to the compensation office’s bank account using the correct payment reference number assigned at employer registration. An annual salary declaration must be submitted to the compensation office by January 30 of the following year, listing AHV-relevant gross income for every employee paid during the calendar year. Late remittances attract interest charged by the compensation office.

 

What changed in the AHV 21 reform and when did it take effect?

 

The AHV 21 reform (Stabilisierung der AHV) took effect on January 1, 2024. The two main changes relevant to payroll are: the combined AHV/IV/EO contribution rate increased from 10.60% (5.30% per side) to 12.10% (6.05% per side); and the reference retirement age for women was harmonized to 65, aligning with men. The rate increase reflects the long-term funding requirement of the AHV system given demographic trends. Employers who did not update their payroll systems to the new 6.05% rate from January 2024 onward have been under-contributing since the reform took effect. The Federal Social Insurance Office (FSIO) publishes the applicable rates each year
