The consultation process on changes to the taxation of large gambling winnings was opened on December 5, 2025.
The amendment to the law aims to restrict the possibility of optimizing taxes by moving to another canton after winning a large amount of money. In future, therefore, winnings of CHF 1 million or more will be taxed at the place of residence at the time of the win.
The Federal Council is thus implementing a motion passed by Parliament.
All winnings from regulated casinos and winnings from lotteries and online games remain tax-free up to (as of January 1, 2026) CHF 1,071,000.
