Week in Insights: Swiss Wealth Tax Rebuff Is a Lesson, Not an End

December 7, 2025, 3:01 PM UTC

Last week, Switzerland informed (or perhaps reminded) the world that efforts to tax extreme wealth shouldn’t start with a knockout punch attempt.

Swiss voters rejected a plan to impose a 50% inheritance tax on estates worth over 50 million francs ($62 million). The results weren’t close; 78% of voters said no to the proposal, which failed by an even steeper margin than a similar initiative in 2015.

The tax would have affected just 0.03% of the population, raised billions, and funded climate policy. But instead of sparking a movement to address wealth concentration, it triggered billionaire exit threats and the specter of economic ruin.

The Swiss left came in too hot. The 50% rate was a bold opening bid for a wealth tax, and it handed opponents an easy target and all the rhetorical ammunition they needed. Detractors could frame the tax as an existential threat to family businesses and, by extension, national competitiveness—even if the reality would have been more modest.

The failed proposal offers a broader lesson for reformers in Switzerland and worldwide. For all the talk of taxing billionaires, you can’t assume you have public buy-in. Step one isn’t setting the ideal tax rate, it’s creating a precedent. Get something on the books that can be worked with, even at a modest rate. Normalize the policy, earmark the revenue for something tangible and popular, and increase the rate later.

Switzerland may have said no to this tax, but it likely hasn’t seen the last wealth tax proposal. Proponents of similar measures should treat this as a strategic misstep that can be used to recalibrate and try again.

The penny’s demise creates a rounding problem for retailers but gives states an impetus to modernize sales tax policy through mandatory e-invoicing and real-time enforcement, Andrew Leahey says in his latest Technically Speaking column.

“A system where every invoice is digitally transmitted to the tax authority at the time of sale isn’t just auditable—it’s self-auditing,” Andrew writes, adding that pairing this with receipt-based lotteries for customers would benefit businesses, governments, and taxpayers. Read More
