Swiss government opposes tax initiative on married couples
Swiss Finance Minister Karin Keller-Sutter launched the campaign against a tax initiative on Tuesday.
The initiative, put forward by the Centre party, goes to a national vote on November 29 and would keep married couples jointly taxed for federal income tax.
It would also require that married couples are not taxed more heavily than unmarried couples living together.
In March 2026, voters approved a move to individual taxation for everyone from 2032, across federal, cantonal and local taxes.
Keller-Sutter says the new initiative could leave couples jointly taxed federally but individually taxed by cantons and municipalities, creating two tax systems at once.
She also argues that joint taxation can discourage second earners, often women, from working and could disadvantage unmarried people.
Depending on how it is implemented, the initiative could cause annual tax revenue losses of up to 3 billion francs, compared with about 630 million francs forecast for the federal tax under individual taxation.
Finance Minister Karin Keller-Sutter launched the government’s campaign against a tax initiative that will go to a vote on November 29.
The initiative would keep married couples jointly taxed for direct federal tax and require that they not be treated worse than unmarried couples.
Keller-Sutter said the initiative could leave federal taxes on married couples operating under a different system from cantonal and municipal taxes.
Voters approved individual taxation in March 2026, and the change is due to apply across federal, cantonal and municipal taxes from 2032.
Keller-Sutter warned that the initiative could cause annual tax revenue losses of up to 3 billion francs, depending on how it is implemented.

Tax system
Swiss government
The government says the initiative could leave married couples jointly taxed at federal level while individual taxation applies to cantonal and municipal taxes.
Mitte initiative supporters
The initiative calls for married couples to continue being jointly taxed for direct federal tax.
Fairness
Swiss government
The government says individual taxation has already addressed the disadvantage known as the marriage penalty and that joint taxation could privilege married couples over unmarried people.
Mitte initiative supporters
The initiative would enshrine in the constitution that married couples must not be treated worse than unmarried couples.
Implementation
Swiss government
The government says the initiative could lead to administrative confusion and delay while cantons continue work on individual taxation.
Mitte initiative supporters
The initiative proposes an alternative calculation, with tax authorities automatically applying the more favourable rate for the couple if the constitutional provision is not implemented within three years.
Voters approved the shift to individual taxation.
Keller-Sutter launched the government’s campaign against the initiative.
The initiative is scheduled to go to a vote.

What people are saying
The goal of abolishing the marriage penalty has already been achieved with the adoption of individual taxation.
This would be an unsettling, complicated scenario.
It is now appropriate to call it a day and let the matter rest.
