Three Quarters

The numbers are in, and they are stark. In 2024, banks, investment funds, and insurance companies generated more than three quarters of Luxembourg's corporate income tax revenue. That is up from 70% the year before.[1]

Finance Minister Gilles Roth, answering a parliamentary question from Greens MP Sam Tanson, revealed that roughly €2.97 billion out of €3.84 billion in total corporate income tax came from the financial centre last year. Revenue from the sector climbed 18.6% between 2023 and 2024, then rose a further 33.3% the following year.[1]

In the first six months of 2026 alone, corporate income tax revenue was already running €1 billion higher than the same period last year, thanks, in the minister's words, to the "dynamism of the financial centre."[2]

The figures speak for themselves. Luxembourg is leaning ever more heavily on its financial centre. The sector's contribution to the national budget has grown from significant to dominant, and the trend is accelerating. A single industry, concentrated in a single city, now funds the majority of the state's corporate tax intake.

There is nothing inherently wrong with a country specialising. Luxembourg has built its modern economy on financial services, and the sector has delivered prosperity, stability, and tax revenue that funds public services. But concentration brings risk. A downturn in financial markets, a regulatory shift in Brussels, or a loss of competitiveness in fund administration could leave a significant hole in the budget. The minister's own figures show that non-financial corporate tax revenue has become almost a rounding error relative to the financial sector's contribution.[1]

The question is not whether the financial centre is good for Luxembourg. It clearly is. The question is what happens if the music stops, and whether anyone is planning for that day.
