The Short Version
Sweden does not have the highest tax rate in Europe by any standard comparative measure. On overall tax burden (tax-to-GDP ratio), Eurostat 2024 data ranks Denmark (45.8%), France (45.3%), and Belgium (45.1%) above Sweden (42.5%). On top personal income tax rates for 2026, Denmark (~55.9–60.5%) and France (~55.4%) both exceed Sweden (~52%). Sweden is undeniably a high-tax country, but the claim that it holds the single highest tax rate in Europe is not supported by the evidence.
