As of January 1, 2025, updates to Germany’s tax legislation regarding the solidarity surcharge (Solidaritätszuschlag) came into effect. The new rules focus on increasing the thresholds for exemption from this surcharge, affecting millions of taxpayers.
The solidarity tax remains at 5.5% of the income tax amount, but as of 2025, new thresholds apply:
Individual taxpayers are exempt from the surcharge if their annual income tax is less than €19,950 (up from the previous €18,130).
Married couples and jointly taxed individuals are exempt when their combined income tax is under €39,900(previously €36,260).
These changes aim to further reduce the tax burden on middle- and low-income individuals.
The solidarity surcharge was introduced after the reunification of Germany in the 1990s as a temporary measure, but it has remained in place. Since 2021, about 90% of taxpayers were exempt from paying the surcharge. The increase in thresholds in 2025 strengthens this trend, making the tax system fairer and more progressive.
Further increases in the thresholds are already planned:
Up to €20,350 for individual taxpayers;
Up to €40,700 for jointly taxed couples.
This will result in even more individuals being exempt from the surcharge.
If you’re unsure whether you fall under the new rules or if you want to optimize your tax strategy, a tax attorney or advisor can:
Conduct calculations to check if the new thresholds apply to you;
Help prepare accurate tax filings;
Offer legal methods for reducing your tax burden;
Represent your interests in disputes with tax authorities.
The increase in the solidarity tax thresholds is an important step toward more equitable taxation. To make the most of the opportunities provided by these legislative changes, it’s recommended to consult with a tax lawyer specializing in this field in a timely manner.
