Swiss voters to decide on individual taxation for married couples

On 8 March 2026, Swiss voters will decide whether married couples should be taxed individually rather than jointly, in a referendum that could significantly reshape the federal tax system. The vote follows parliamentary approval of a reform aimed at ending what is commonly referred to as the “marriage penalty.”

 

Background: Joint taxation and the “marriage penalty”

Under the current system, married couples submit a single tax return and are taxed jointly. For many dual-income households, this can result in a higher tax burden than that borne by two unmarried individuals with the same combined income.

Although various corrective mechanisms exist within the current framework, critics have long argued that joint taxation creates structural disadvantages for certain household models.

 

The Proposed Reform

The reform would introduce individual taxation for married couples at the federal level. Each spouse would file separately and be taxed under the same rules that apply to unmarried individuals.

According to supporters, the reform aims to:

• Improve tax neutrality
• Reduce work disincentives for second earners
• Reflect evolving household structures

The Federal Council has argued that the change could support labour market participation.

The legislative package also includes adjustments to tax scales and higher child deductions intended to mitigate potential negative effects.

 

Points of Debate

Opponents of the reform warn that individual taxation could:

• Disadvantage single-income households
• Increase administrative complexity
• Affect the distribution of tax revenues between the federal government and the cantons

They argue that the current system already contains mechanisms designed to reduce disparities.

 

Outlook

If approved, the reform would mark a significant structural change to the federal tax framework and could have meaningful implications for households, workforce participation, and intergovernmental fiscal balances.

Further developments will depend on the outcome of the referendum and, if adopted, on the implementation process at the federal and cantonal levels.
