German tax revenues up 2.6% in May, finance ministry says

German tax revenues grew 2.6% year-over-year in May, a significant slowdown compared to the previous three months' gains of over 8%, with total revenue reaching 62.8 billion euros. While income and sales tax increased, withholding tax on interest and capital gains showed no significant growth for the first time in a year. Despite raised economic forecasts for the year, the finance ministry anticipates limited momentum in the coming months, citing uncertainty in international trade policy and expecting declining income tax growth rates in 2025.

Analysis

German federal and state government tax revenues experienced a notable deceleration in May, rising only 2.6% year-over-year to 62.8 billion euros, a stark contrast to the significantly higher growth rates observed in April (10.2%), March (11.1%), and February (8.1%). While income and sales tax contributions increased, a key development was the stagnation in year-on-year growth for withholding tax on interest and capital gains, marking the first such instance since May 2023, potentially indicating shifts in investment income or capital gains realization. Despite this slowdown, cumulative tax revenue from January to May 2025 rose 8.3% year-on-year to 349 billion euros. The finance ministry projects limited economic momentum in the near term, citing uncertainties in international trade policy as a primary concern, even though four German economic institutes recently upgraded their growth forecasts for the current year. Furthermore, the ministry anticipates declining growth rates for income tax in 2025, attributing this to the incorporation of wage increases from collective bargaining into the comparative baseline and a subdued labor market, suggesting potential future fiscal pressure.

Key Decisions for Investors

• Investors should interpret the significant slowdown in May's tax revenue growth, particularly the flat withholding tax on capital gains, and the finance ministry's cautious outlook as potential leading indicators of cooling economic activity in Germany, warranting a more nuanced view despite recent optimistic institutional forecasts.
• Monitor upcoming German macroeconomic indicators, especially international trade data and labor market reports, to assess if the May tax revenue deceleration marks the beginning of a sustained trend or a temporary fluctuation.
• Consider reviewing exposure to German equities and sectors highly sensitive to domestic consumption and export performance, and factor in the projected decline in income tax growth for 2025 when assessing the medium-term fiscal landscape and its potential impact on sovereign risk or public spending.
