Open the N26 app on any given morning and, for a significant number of its customers across Europe, the number at the top of the screen is not the one they expect to see. It is not a reassuring green figure showing the money set aside for rent, groceries or a long-planned holiday. It is a red one, with a minus sign in front of it.
Across Trustpilot, Reddit, X and the comment sections of consumer finance blogs, the picture is remarkably consistent. Customers of the Berlin-based neobank — one of Europe’s most prominent fintech success stories, with millions of users across the continent — describe logging in to find accounts that have slipped into negative territory. Some are down a few euros. Others report balances of minus fifty, minus one hundred, minus several hundred. The amounts vary. The frustration, on the evidence of the public complaints, does not.
“I barely used the account, yet closing it turned into a complete nightmare,” one customer wrote in a review posted earlier this year, describing a situation in which a small negative balance spiralled into a prolonged dispute with customer support. It is a pattern echoed by dozens of others who have taken to public forums to share screenshots of their apps, timestamps of unanswered support tickets, and long threads of increasingly exasperated messages.
A quiet problem, loudly discussed
What makes the phenomenon striking is not any single case but the sheer volume of them. Scroll through the recent reviews of N26 on consumer feedback platforms and a recurring theme emerges: people who say their accounts have gone into the red, and who say they are struggling to get a clear answer about how to resolve it. Some describe waiting days for a response from support. Others say they were told the issue was being looked into, only to check back later and find the negative balance unchanged — or, in some accounts, grown larger as additional charges accrued while the case remained open.
The stories come from Germany, France, Spain, Italy, Austria and beyond. They come from long-standing customers who say they were loyal to N26 for years, and from recent sign-ups whose relationship with the bank began badly and never recovered. The common thread is the minus sign, and the sense — repeated again and again in these accounts — of not being fully in control of one’s own money.
What the bank’s own rules say
N26’s published terms make clear that a negative balance is not, in itself, an anomaly. The bank’s support pages state that accounts can go into the red in a range of routine circumstances, including offline card payments processed after the fact, fees for certain services, and overdraft arrangements where eligible. Customers are formally obligated, under the bank’s terms and conditions, to bring the account back to zero promptly. They receive email reminders, and the account remains active for sixty days before the bank is entitled to close it.
In other words, a negative balance at N26 is a known category of event with a defined process attached to it. What the public complaints raise is a separate question: how smoothly that process works in practice when a customer does not understand why the minus sign appeared, or cannot reach a human being quickly enough to discuss it.
The human side of a digital bank
Part of what has drawn attention to the issue is the gap between expectation and experience. N26 built its reputation on the promise of banking reimagined for the smartphone generation — slick, transparent, free of the opacity associated with traditional high street banks. Its customers, by and large, signed up precisely because they wanted clarity: real-time notifications, intuitive app design, immediate visibility into every euro.
A negative balance that a customer cannot immediately explain, therefore, lands differently here than it might at a legacy institution. Users describe the experience in almost emotional terms — the jolt of opening an app to see a minus sign, the hours spent scrolling through transactions trying to pinpoint the cause, the uneasy sense that money they thought was theirs has quietly gone somewhere else.
A company under scrutiny
N26 is no stranger to public attention. The bank has spent the past several years navigating a period of significant regulatory oversight in Germany, alongside the ordinary pressures of scaling a technology business to millions of users across multiple jurisdictions. It has repeatedly said, through public statements and press communications, that it takes customer feedback seriously and is investing in its support operations.
For the customers currently watching their balances sit stubbornly below zero, however, the question is more immediate. They want to know when the minus sign will disappear, what they are expected to do about it, and who they can speak to in the meantime. Until those questions are answered to their satisfaction, the reviews — and the screenshots — seem likely to keep coming.

Their DevOps engineers fucked up totally
-23,000 euro on the account now and support can’t help
Their support is useless….
i noticed it this morning. what the fuck is happening there in germany? where is my money?
Actually, I also tried to get in contact with their support and it was useless and then I contacted their higher management, they are saying it was a bug ONLY with the users who had connected crypto wallets or platforms or something. i had -725,000 euro on the account this morning and now it is already settled
How did you manage to settle it? I still have minus on my acc and support cant do anything about it???
One of Gino’s friends is my friend too who is working down there in Berlin. I am bridging one of my platforms with the OnRamper, and I was told that is why my account was flagged in their system. They told me, they needed system to reboot my account balance with 12% of debt that was showing in there
You mean crypto related accounts are the one that were flagged and bugged?
Yes
I used my German account to transfer to the N26 so it would be in the same day, after funds came I just sent it back to my account but it was enough to make system reboot and the debt is gone now
