How the first pillar works in the Canton of Vaud. Cantonal Compensation Fund Guide, Contribution Gaps and Supplementary Benefits for Minimum Living.

Context

In brief

AVS: 5.3% employee contribution; retirement age 65 for men
PC: cantonal benefits to cover the minimum living standard when the pension is insufficient
Vaud Compensation Fund: manages contributions, pension calculations, and PC access

Key facts

What: Three-pillar pension system; AVS is the mandatory first national pillar
Who: UFAS/BSV (federal office), Vaud cantonal compensation fund
Where: Canton Vaud, French-speaking Switzerland
When: Contributions throughout working life; pension from the set date
Amount: 5.3% gross employee, 5.3% employer; self-employed 10.6% on net income

In Canton Vaud, the Swiss pension system is structured into three pillars: the first is AVS (Old-Age and Survivors' Insurance), the second is LPP (mandatory occupational pension), and the third is individual private savings. The Vaud cantonal compensation fund is the administrative body that manages, at the local level, the inflow of AVS contributions, the calculation of pensions, and support for supplementary benefits (PC).

AVS is a mandatory scheme for anyone working or residing in Switzerland. An employee pays 5.3% gross of their salary as an AVS/AI/IPG contribution (covering old age, disability, maternity allowance). The employer pays an additional 5.3%, totaling 10.6% of the wage bill. Self-employed individuals pay 10.6% on their net income from self-employment, in two semi-annual installments.

Operational details

Contributory gaps: nature and recoverability

A contributory gap arises when a year of insurance has no contributions or only partial ones. The causes can be involuntary — periods of unemployment, maternity/paternity leave, illness, injury — or voluntary, such as a work interruption for personal reasons. The good news is that many gaps are recoverable. The Vaud cantonal compensation fund allows for retroactive contributions to be paid within certain deadlines and under specific conditions. Those who were unemployed and received unemployment benefits (AD/AC) will have automatic contributions credited by the unemployment fund. Those on maternity leave benefit from contributions covered by the health insurance fund or the institution that provided the subsidy.

Voluntary gaps — years in which you did not work by choice — are harder to fill: the payment is optional and must be actively requested from the fund. Only the last 10 years of voluntary gaps can generally be recovered, at the discretion of the compensation fund.

Pension calculation: formula, indices, and impact

The AVS pension is not calculated as a simple percentage of the average salary. The formula considers:

1. Number of contribution years: from a minimum of 1 year up to 44 years for full pension entitlement. Those with fewer than 44 contribution years receive a proportionally reduced pension. 2. Average annual salary: determined based on contributions paid throughout the working life, updated each year according to the salary index published by UFAS/BSV. 3. Salary index: UFAS/BSV updates this index annually to reflect national salary inflation. The pension amount is revalued each year.

Step-by-step procedure to request supplementary benefits in Vaud

The process is administrative, managed by the Vaud cantonal fund. Here's how it proceeds:

1. Contact the fund well in advance Don't wait until the day of retirement. Contact the Vaud cantonal compensation fund well before the expected retirement date. During this interview (often available via videoconference), the fund verifies if you are eligible for supplementary benefits based on your estimated income and declared assets.

2. Gather the necessary documents Prepare to provide: contribution extract (automatically provided by the fund); documents of total income (tax forms, self-employment income certificates if applicable); rental contract or property certificate of the residence; lists of current expenses (utilities, insurances); asset declarations (bank statements, securities balances).

3. Complete the official request The fund provides a standardized form for the supplementary benefits application. It is not particularly complicated, but it must be filled out accurately: full names, dates of birth, account numbers, income and asset amounts declared exactly.

4. Send the application to the Vaud fund You can send the application by regular mail to the fund's address, or deposit it directly at the cantonal offices if present in your municipality of residence. Always keep a copy for your personal records.

5. Wait for the decision The fund processes the application in times that vary depending on the administrative load; it is generally prudent to expect several weeks. If doubts arise about income, assets, or other information, the fund contacts you for clarification requests or additional documentation.
