"European corporate tax" is not one thing. Same continent, same single market, wildly different tax bills. The spread is the whole story. - Hungary at 9% sits at the low end. Other countries run roughly three times that. - EU directives, patent boxes, national incentives, and treaty networks stack on top of the headline. Two companies in the same country can pay very different effective rates. - Benchmark honestly: the US federal 21% sits mid-table globally. I have seen people call a 25% European rate "high" while their all-in US number was nearly the same. - Compare the full stack or do not bother. Our 212-jurisdiction table covers all of Europe, refreshed for 2026.
