Cantonal Tax: A Comparison Between Switzerland in 2026 and Bern (cross-border guide)

Context

At a Glance

• Taxation occurs at three levels: federal, cantonal, and municipal
• Each canton applies its own laws and multiplier
• The municipality applies a multiplier to the cantonal tax
• AFC/ESTV administers direct federal tax and VAT

Key Facts

• Levels → direct federal tax, cantonal tax, and municipal tax
• Cantons → their own laws and multipliers
• Municipalities → a multiplier applied to the cantonal tax
• AFC/ESTV → direct federal tax and VAT
• LAMal/KVG → mandatory for residents

The Swiss tax system consists of three levels: direct federal tax, cantonal tax, and municipal tax. When analyzing the 2026 comparison for the Canton of Bern, these three components must be considered separately, because each canton has its own law and multiplier, while municipalities apply a multiplier to the cantonal tax.

Agencies and Responsibilities

The AFC/ESTV oversees direct federal tax and VAT. Cantonal administrations, on the other hand, oversee the cantonal and municipal components. The result cannot be expressed as a single national percentage: the federal portion remains distinct from cantonal regulations and the municipal multiplier.

The Federal Social Insurance Office (UFAS/BSV) has a different role. It is responsible for social security, including AVS, AI, and LPP, but does not set tax rates. The Federal Statistical Office (UST/BFS) also plays a statistical role and does not establish tax rates. This distinction is intended to avoid confusion between those who administer tax collection and those who produce statistics or oversee social security.

For those comparing Bern with other cantons, the practical sequence is therefore fixed: first, separate out the direct federal tax; then examine the cantonal portion; and finally, consider the municipal multiplier. The same framework must be maintained when using dichiarazione delle imposte; otherwise, there is a risk of comparing different components.

AVS/AI/IPG, AD/AC, LAINF/LAA, and LPP/BVG also belong to a separate category: payroll contributions. They are not the fourth tier of cantonal tax; they must be kept separate in the 2026 comparison.

Operational details

Items to keep separate

The calculation of the salary and the cantonal tax are not the same. Social security or insurance contributions may appear on the salary that follow different rules from the comparison between cantons.

Contributions and awards

For AHV/IV/EO, the employee's share is 5.3%; the total with the employer is 10.6%. AD/HC is worth 1.1% up to the annual ceiling. UVG/LAA ranges from 0.7% to 1.5% depending on the sector. For BVG/BVG, the percentages indicated on the coordinated salary are 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.

These items do not become cantonal tax rates just because they appear in the salary calculation itself. In the comparison on Bern, it is therefore clearer to keep a tax freeze and a contribution freeze, without automatically adding up quantities that have different functions.

The KVG follows yet another logic. For residents, it is a compulsory health insurance policy to be taken out within three months of arrival; it works with per capita premiums, not with a tax or wage contribution. Premiums vary by canton or region, and the premium reduction is cantonal. For adults, the available deductibles are CHF 300/500/1000/1500/2000/2500.

The cost of living should therefore not be read through the cantonal tax alone. The same caution is needed when comparing work: in Switzerland there is no federal minimum wage, although some cantons have their own. This is a figure to be kept separate from the tax grid.

Finally, legitimate optimisation strategies require up-to-date figures. The third pillar 3a ceiling, the BVG coordination threshold or deduction, the AD/AC ceiling, the average KVG premiums and the median salary are indexed figures each year.

Key points

Practical Procedure for Bern

The 2026 comparison for the Canton of Bern becomes operational once each item is assigned to the correct level. A brief procedure prevents the use of a municipal multiplier as if it were a cantonal tax rate or the inclusion of LAMal premiums in the tax levy.

Five Operational Steps

1. Identify the scope. Specify the Canton of Bern and the reference municipality. The canton should be interpreted according to its own law and multiplier; the municipality according to the multiplier applied to the cantonal tax.

2. Identify the responsible authorities. For direct federal tax and VAT, the reference is the AFC/ESTV. For the cantonal and municipal components, consult the cantonal administrations. The Federal Social Insurance Office (UFAS/BSV) and the Federal Statistical Office (UST/BFS) are not involved in tax determination: the former oversees social security, while the latter handles statistics.

3. Update the 2026 figures. Do not set amounts without verifying the 3a contribution limit, the LPP coordination threshold or deduction, the AD/AC limit, the average KVG premiums, and the median wage. These figures are indexed annually; use the updated official source.

4. Set the salary aside. Record AVS/AI/IPG, AD/AC, LAINF/LAA, and LPP/BVG separately. This prevents contributions and taxes from being added together and allows you to determine labor costs without converting contribution percentages into cantonal tax rates.

5. Check KVG requirements and planning. If you are a resident, health insurance is mandatory and must be obtained within three months of arrival. For adults, deductibles are CHF 300/500/1,000/1,500/2,000/2,500; premiums vary by canton or region, while premium reductions are determined at the cantonal level. For lawful optimization, apply only rules and figures verified for the specific canton and year in question.
