AHV and supplementary benefits in Basel-Stadt (cross-border guide)

Context

In brief

• Basel-Stadt: Cantonal Pension Fund and First Pillar
• AHV pension requires attention to contribution gaps
• Supplementary benefits cover the minimum subsistence
• FSIO/BSV follows pension provision, not taxes

Key Facts

• Topic → AHV/AHV and supplementary benefits in the Canton of Basel-Stadt
• Reference → cantonal compensation office
• Calculation → AHV pension and contribution gaps
• Function → coverage of the minimum subsistence
• AHV/IV/EO contributions → 5.3% employee; 10.6% overall with employer
• Social competence → FSIO/BSV

In the canton of Basel-Stadt, the first pillar is structured around a cantonal compensation office, the calculation of the AHV pension, the verification of contribution gaps and supplementary benefits intended to cover the minimum subsistence. They are four coordinates of the same path, but they do not indicate the same thing.

The perimeter of the verification

For the reader, the first distinction concerns AHV/AHV and supplementary benefits. The AHV pension must be read through its calculation; contribution gaps are the point to be checked when reconstructing the pension position. Supplementary benefits, on the other hand, belong to the chapter of minimum subsistence coverage. Separating these plans avoids looking for a single answer to different questions.

On salary, the AHV/IV/EO contribution is 5.3% for the employee and 10.6% overall with the employer. The BVG/BVG, on the other hand, uses the coordinated salary and different percentages for each group: 7% between 25 and 34 years old, 10% between 35 and 44, 15% between 45 and 54 and 18% from 55 years old up to the reference age. The distinction serves to read the pension items separately, without transforming the BVG data into an AHV figure.

The offices also have different responsibilities. The FSIO/BSV concerns social security — AHV, IV and BVG — and does not set taxes. The FTA/ESTV concerns direct federal tax and VAT. The cantonal administrations are responsible for cantonal and municipal tax; for statistics, the reference is FSO/BFS. For a coordinated reading of the first pillar and the BVG, see guida AVS e LPP.

Operational details

The practical question changes depending on the problem. If you try to understand the pension, the path concerns AHV/AHV, calculation and contribution gaps. If you ask how to cover the minimum subsistence, the point is that of supplementary benefits. The connection with the cost of living should therefore be read through this second topic, without confusing the result of the pension with the supplementary coverage.

Three paths that should not overlap

In a hypothetical scenario, a person notices that their contribution history has a gap. The first check concerns the AHV position and the calculation of the pension; the question about supplementary benefits comes from a different level, because it concerns the coverage of the minimum subsistence. In practice, the procedure starts from the distinction between the two questions and not from the attempt to use a pension figure as an automatic answer to the minimum subsistence.

Another confusion concerns the KVG. For residents, it is compulsory and must be taken out within 3 months of arrival. It is a per capita premium insurance, not a tax or a wage contribution. Premiums vary by canton and region, while the premium reduction is a cantonal subsidy. This item may weigh on the family budget, but it does not change the meaning of supplementary benefits: their focus is on the coverage of the minimum subsistence.

Taxes also follow a separate circuit. The system has three levels: direct federal tax, cantonal tax and municipal tax. Each canton has its own law and multiplier, and the municipality applies the multiplier to the cantonal one. If the doubt concerns these levies, the reference is not the FSIO/BSV: the FTA/ESTV for direct federal tax and VAT come into play, as well as the cantonal administrations for cantonal and municipal taxes.

Key points

The most straightforward approach is to keep the questions separate before looking for figures or answers. The topic of AVS and supplementary benefits in Basel-Stadt can be addressed using a simple step-by-step process.

A Practical Step-by-Step Guide

1. Define the question. Specify whether the inquiry concerns the calculation of the AVS/AHV pension, a contribution gap, or the subsistence minimum. These are different inquiries and lead to different paths.

2. Start with the cantonal reference. For pension calculations or contribution gaps, focus your inquiry on the cantonal compensation fund. The UFAS/BSV remains the point of reference for social security but does not set tax rates.

3. Review the deductions by category. AVS/AI/IPG amounts to 5.3% for the employee and 10.6% total including the employer; AD/AC is 1.1% up to the annual cap, while LAINF/LAA ranges from 0.7% to 1.5% depending on the sector. LPP/BVG must be treated separately and uses the coordinated salary.

4. If the question concerns the minimum subsistence level, keep the section on supplementary benefits separate. If it concerns health insurance premiums, refer to the LAMal/KVG: coverage is mandatory for residents, must be obtained within 3 months of arrival, and may qualify for a premium reduction as a cantonal subsidy.

5. If the issue is tax-related, refer the matter to the appropriate authority. The AFC/ESTV handles direct federal tax and VAT; cantonal administrations handle cantonal and municipal taxes.

Before using any amounts, always check the reference year. The 3rd pillar (3a) contribution limit, the LPP coordination threshold or deduction, the AD/AC limit, the average LAMal premiums, and the median wage are figures that are indexed annually. The correct value must therefore be taken from the official source for the relevant sector.
