Marriage Initiative: What Is Actually Decided on 29 November

On 29 November, Swiss voters will decide on the popular initiative «Yes to fair federal taxes for married couples too – finally abolish discrimination against marriage!». The title sounds like an old dispute over the so-called marriage penalty. But the starting point is new: in March, voters already approved the Federal Act on Individual Taxation. It is to enter into force by 2032 at the latest.

Anyone who wants to understand the November proposal must therefore keep two questions apart. The first is: how should married couples be treated under direct federal tax? The second: what happens to the already decided switch to individual taxation? The vote answers the first question directly, but not the second conclusively.

What the initiative would write into the constitution

The wording of the initiative is clear in principle and open on how it would be implemented. A married couple's income is to be added together. At the same time, the law is to ensure that married couples are not disadvantaged compared with other taxpayers. The proposal concerns direct federal tax.

It does not, however, prescribe a complete new rate schedule. Nor does it set out which family would be relieved by how many francs. The legislature would have to decide on the concrete implementation. If no implementing provisions apply three years after approval, the initiative text provides for an ordinance by the Federal Council. Alongside joint calculation, this would have to provide for an alternative calculation with a rate schedule and deductions for unmarried persons; the lower amount would be owed.

That sounds technical, but it is central. The initiative does not simply guarantee a blanket tax cut for all married people. Its effect depends on later legislation – and for individual households on, among other things, how income is divided, children and deductions. It also concerns direct federal tax here, not automatically every cantonal or municipal tax bill.

Individual taxation has already been decided

On 8 March 2026, the Federal Act on Individual Taxation was adopted with 54.23 percent of votes in favour. This model taxes people individually, regardless of marital status. In August the Federal Council decided to bring the act into force by 2032 at the latest. This gives the cantons time to adapt their laws and technical processes.

This reform also pursues the goal of removing disadvantages for married couples, but it starts at the system level: the basis is not the couple's joint income but the individual incomes. The November initiative chooses the opposite constitutional starting point. It wants to retain the addition of incomes and rule out any disadvantage within that system.

So this is not merely about the size of a deduction. It is about whether the taxation of married couples should be organised as a joint or an individual system. Both approaches can change differences in the tax burden, but they do so in different ways.
