Switzerland faces controversy over the "marriage penalty," a potential financial disadvantage some couples might experience due to taxation upon marriage.

High-earning couples facing tax disadvantages opt for unrecognized marriages, tax separation, and a decrease in female workforce participation rates.

Switzerland faces controversy over the "marriage penalty," a potential financial disadvantage some couples might experience due to taxation upon marriage.

In Switzerland, a long-standing debate has been unfolding regarding the "marriage penalty" tax, a situation where married couples with two working spouses often face higher combined tax rates than two equivalent unmarried individuals living together. This issue, known as the marriage penalty, has implications for employment, family dynamics, and tax revenues.

The Marriage Penalty and Its Impacts

The marriage penalty, prevalent in many Swiss cantons, results in married couples paying more taxes than unmarried couples with similar incomes. This financial disadvantage may discourage the second spouse, often the woman, from entering or remaining in the workforce, potentially reducing overall female employment rates or labor market participation within families subject to this tax penalty.

Furthermore, the financial disadvantage might influence couples’ decisions on marriage and labor division, potentially encouraging unmarried cohabitation or traditional single-earner family models to avoid tax burdens.

In terms of tax revenues, abolishing the marriage penalty would likely reduce tax revenues from married dual-earner households in the short term since tax burdens would be lowered. However, by encouraging higher labor participation of the second spouse, it might broaden the tax base over time, partially offsetting revenue losses.

Current Situation and Proposals

While no concrete legislative changes or proposals to abolish the marriage penalty were identified in the recent search results up to August 2025, the debate continues. The liberal FDP in Switzerland sees the abolition of the marriage penalty as a means of combating the skills shortage by encouraging more people to work.

In contrast, conservative parties, including the Swiss People's Party (SVP) and The Centre, oppose the abolition of the marriage penalty. They argue that it could lead to a loss of tax revenues and potentially disadvantage single-income families and stay-at-home parents under the proposed individual taxation system.

Another proposal from conservative parties is a splitting model similar to Germany's, where partners' incomes are aggregated but taxed at half the rate. This approach would maintain some level of tax advantage for married couples while addressing the marriage penalty to some extent.

The Future of the Marriage Penalty Debate

The dispute over the marriage penalty is seen as a power struggle between progressive and conservative voices in family policy. The Swiss Parliament has decided to abolish the marriage penalty, a tax disadvantage for couples where both partners work. However, the SVP and The Centre are advocating for a referendum to prevent this abolition.

Observers consider the current debate as a continuation of this power struggle between progressive and conservative voices in family policy. The outcome of this debate could have significant implications for employment, family dynamics, and tax revenues in Switzerland.
