Shocking Ways Germany Wastes YOUR Tax Money: The Billion-Euro Burn
You pay thousands in taxes, but where does it go? We reveal the most outrageous ways the German government wastes your hard-earned money in 2025. 💸
Key Takeaways
- Germany’s annual budget sees billions in tax money wasted on non-sensical projects, as exposed by the 2025 “Schwarzbuch” report.
- Protected bats in railway tunnels caused costs to explode from €49 million to €207 million, halting the project’s completion.
- A venue restoration meant for 2020 reached €221 million, resulting in massive operating deficits and exorbitant daily rental fees.
- Billionaire Kühne’s opera house actually costs taxpayers €311 million in infrastructure, while Kühne has the right to veto the design.
- Despite a guaranteed price, Hamburg’s youth prison costs surged to €430 million under a high-priced “rent instead of own” model.
- Contaminated land and planning errors delayed this project for a decade, with costs nearly tripling to a staggering €476 million.
- After ten years and €40 million spent without construction, the Port Museum budget has climbed from €185 million to €500 million.
- Fire safety delays and poor planning pushed renovation costs to €417 million, with a reopening now delayed until at least 2031.
- A failed battery factory project potentially cost taxpayers €1 billion in lost loans and bonds, risking Chinese investor buyouts instead.
- Modeled after the infamous Stuttgart 21, this renovation could cost up to €3 billion and take 30 years to finish.
- Germany spent €7 billion on six billion masks, half of which were destroyed, while storage costs alone hit €500 million.
- While 14 billion Euros is wasted on these projects, it represents a fraction of Germany’s vast 500-billion-euro annual budget.

More InformationWhere Does Your Money Really Go?
You pay thousands of Euros in taxes every year—and we do too. Thanks to our taxes, this country can keep on running, funding everything from the legendary Autobahn to the social safety net. But have you ever asked yourself where all your money actually goes? And who truly decides how to spend it? What if we told you that billions of Euros are wasted every single year on projects that make absolutely no sense at all?
That’s exactly what the Schwarzbuch (Black Book) from the German Taxpayers’ Association exposes. We read this entire report, and we found ourselves laughing and crying at the same time. The scale of mismanagement is breathtaking. We will show you the 10 most shocking ways the German government burns through YOUR taxes, highlighting the systemic failures in planning and execution that define modern German bureaucracy. It all starts with a project that prioritize wildlife over transit efficiency.
The Hermann Hesse Railway: The 200-Million-Euro Bat Tunnel
The Hermann Hesse Railway in Baden-Württemberg began as a small line meant to reconnect the towns of Calw and Weil der Stadt. The plan in the early 2000s was simple: reopen the old track by 2018 to better connect the Black Forest to the Stuttgart metropolitan region. But today, no train is running. The reason? Bats. Around 1,000 protected bats live in two tunnels along the route. Instead of relocating them, which would have been the logical economic choice, engineers were forced to build a “tunnel inside the tunnel,” complete with complex lighting systems and ultrasound technology to guide the animals.
What began as a modest 49-million-euro project has now exploded to a staggering 207 million Euros—and the line remains unfinished. It is a classic example of how strict environmental regulations can paralyze infrastructure and drain taxpayer coffers without delivering a single commute.

More InformationBeethoven Hall Bonn: Music for the Masses?
Just like the Beethoven Hall in Bonn, a historic concert venue named after the city’s most famous son. It was supposed to be fully restored in just three years, ready for Beethoven’s 250th birthday in 2020. However, five years after that deadline, the hall only recently officially reopened in December 2025. What began as a 43-million-euro project has now soared to more than 221 million Euros.
Because of those skyrocketing costs, renting the main hall now costs over €20,000 per day—four times more than before the renovation. The city now fears that this high rent will drive away organizers, leaving the venue empty and costing taxpayers an additional operating deficit of 2 to 3 million Euros per year. We have paid over five times the original price for a hall that many cultural groups can no longer afford to use.
The "Gift" of the Kühne Opera in Hamburg
Let’s talk about two projects in Hamburg that highlight the city’s struggle with large-scale management. A new opera house is being planned in the HafenCity, promoted as a generous “gift” from billionaire Klaus-Michael Kühne. He wants to fund the construction through his foundation and then hand the finished building over to the city. While that sounds like a win for residents, this so-called “Kühne Opera” is turning into an expensive deal for taxpayers.
The city still has to cover land preparation, flood protection, and infrastructure, all while keeping the old opera running until 2034. Altogether, public costs add up to more than 311 million Euros. Furthermore, the deal grants Kühne a veto in the design process, making it feel more like he is buying influence rather than offering pure generosity. Is it really a “gift” when the public pays hundreds of millions for a private vision?

More InformationBillwerder: The Premium-Price Youth Prison
Hamburg isn’t just wasting your tax money on high culture; they are also burning it on what was supposed to be Germany’s most modern youth prison in Billwerder. The project was originally planned to cost 165 million Euros with a “guaranteed maximum price.” But in German bureaucracy, that guarantee didn’t mean much. Costs have already climbed to 192 million Euros. Because the prison is built under a “rent instead of own” model, higher construction costs translate directly to higher rent.
The annual rent has jumped from 8.6 to 11.7 million Euros, which works out to more than €42 per square meter every month. In total, taxpayers could end up paying over 430 million Euros for this “maximum-price” project. Seeing these projects, it’s easy to get frustrated because we can’t stop the government from wasting our money. But what you can do is ensure YOU are not overpaying your own taxes by seeking expert financial advice.
Zwickau-Marienthal: The Unfinished Prison
From one prison to another, the new correctional facility in Zwickau-Marienthal was planned to cost 150 million Euros back in 2014. But more than 10 years later, the prison remains unfinished. The site turned out to be contaminated, and after years of planning errors and failed tenders, construction stopped completely in 2024.
By now, over 230 million Euros have already been spent on a half-built facility. The earliest opening date is now projected for 2030, and the total price tag has exploded to 476 million Euros, plus another 24 million set aside for “risk reserves”. This project illustrates a recurring theme in German infrastructure: a failure to properly assess site conditions before spending hundreds of millions in public funds.

More InformationThe German Port Museum: A Museum Without Walls
Let’s move into the top five wasteful projects, returning to Hamburg. The German Port Museum was supposed to be a national landmark celebrating maritime trade. The project started back in 2015 with an opening planned for 2025. But 10 years later, not a single brick has been laid. The foundation behind it still hasn’t delivered a proper plan or cost estimate, and the chosen site sits dangerously close to chemical plants using hazardous materials like chlorine gas.
The original budget was 185 million Euros, but new estimates put the total cost at nearly 500 million Euros. Almost 40 million Euros have already been spent on a museum that literally does not exist yet. This is a staggering misuse of funds for a project that lacks even a basic construction timeline.
Augsburg State Theater: A Century of Delays
Number four takes us to Augsburg, home to one of Germany’s most expensive theater renovations. The State Theater has been closed since 2016 due to fire safety issues and outdated technology, some of which dated back to the 1930s. It’s been dark for nine years and will stay closed for at least another six, with reopening not expected before 2031.
The project has been plagued by poor planning, endless delays, and a planning office that had to be replaced after faulty work. Redesigns to preserve historic remains pushed costs even higher. What started at 186 million Euros has now climbed to 417 million Euros. Experts warn it could exceed 600 million before the curtain finally rises, leaving an entire city without its primary cultural venue for nearly two decades.

More InformationNorthvolt: The Billion-Euro Green Gamble
Number three is the insolvency of the Swedish company Northvolt. You might ask how your tax money is lost if a private Swedish company goes bankrupt. Northvolt was supposed to build a massive battery factory in northern Germany, a flagship project to make Europe less dependent on China. But the company filed for bankruptcy, leaving behind billions in debt and an unfinished factory near Heide.
The state-owned KfW bank invested 600 million Euros through a convertible bond that is now effectively gone, and another 420 million are at risk from an older German loan. Altogether, up to 1 BILLION Euros of taxpayer money could vanish. The ultimate irony? The remains of Northvolt might now be sold to a Chinese investor—the very dependency this project was meant to end.
Stuttgart's "Opera 21": A Budget Sinkhole
We’ve already heard about operas, but Stuttgart is taking things to the next level with its own “Opera 21.” Just like the infamous Stuttgart 21 train station, this renovation has turned into a billion-euro tax sinkhole. The historic State Opera, built in 1912, urgently needs renovation. Its stage machinery dates back to the 1980s, and working conditions are unacceptable.
The project was first budgeted at 960 million Euros in 2019, but constant delays and rising prices have pushed that figure to around 2 billion Euros. Critics warn it could even reach 3 billion before it is done. The timeline is just as dramatic: the first performance in the renovated opera house isn’t expected before 2043—nearly 30 years after planning first began.

More InformationPandemic Mask Waste: The €7 Billion Mistake
Finally, we come to number one: the government’s mask purchases during the pandemic. This is one of the biggest cases of waste in modern German history. In early 2020, the health ministry promised every supplier a fixed price of €4.50 per FFP2 mask. This sparked a buying frenzy where Germany ended up ordering nearly six billion masks.
Less than a third were ever used, and more than HALF had to be destroyed after they expired. Storing and managing this mountain of unused masks has cost another half a billion Euros, and ongoing lawsuits from suppliers could add hundreds of millions more. In total, this “pandemic panic shopping” could cost taxpayers well over 7 billion Euros.
Putting Waste into Perspective
Altogether, these 10 projects have wasted nearly 14 billion Euros of taxpayer money. That is a staggering amount, but to put it in perspective, it is still only about 3% of Germany’s 2025 federal budget, which totals more than 500 billion Euros.
While we can’t stop the government from burning money on bat tunnels and expired masks, we can take control of our own financial health. The government might be wasteful, but that doesn’t mean you have to be. By optimizing your own tax situation, you can at least ensure you are keeping as much of your hard-earned income as possible.
