Dutch MPs voted on Thursday to tax the biggest fortunes harder, passing an amended 2027 tax plan by 76 votes, one more than a majority in the Tweede Kamer. The plan adds a top rate of 38.5% on returns above €60,000 a year from savings and investments, and cuts the standard rate on those returns from 36% to 35.5%.

Two of the three parties in Prime Minister Rob Jetten's coalition, D66 and CDA, wrote the change with the opposition parties PRO and Volt on Wednesday. The third partner, the VVD, voted against it. ChristenUnie, DENK, the Party for the Animals and 50Plus voted with D66, CDA, PRO and Volt.

The amendment moves about €1 billion of tax onto wealthier households and cuts the burden on middle and lower-income households by €900 million. "If this proposal is adopted, the Netherlands will introduce a millionaire's tax," PRO leader Jesse Klaver said.
