Insolvency of a German GmbH: director duties, deadlines — and what to do now

Insolvency is the scenario every managing director wants to avoid: a GmbH — Gesellschaft mit beschränkter Haftung, the German limited-liability company — can no longer make payments as they fall due, and from that point on it is not just the business side that decides what happens next, but German insolvency law. The good news is that it rarely arrives without warning. A business that watches its liquidity weekly generally sees the shortfall coming weeks in advance — and that lead time is what decides whether it stays a squeeze or turns into a genuine crisis; the groundwork is covered in the guide to cash flow forecasting.

This guide explains the three statutory grounds for insolvency under German law, the managing directors’ duties and deadlines, how to tell actual insolvency apart from a temporary cash flow shortage — and the immediate steps that matter once things get tight.

Legal note: This article explains the underlying business mechanics and sets out the broad statutory framework under German law. It is not legal advice and does not replace it. Whether actual insolvency or a filing duty applies in a specific case is a legal assessment — bring in a law firm specialising in German insolvency and restructuring law, or a restructuring advisor, early. This is specifically a feature of German law: the tests, filing duties and directors’ liability that apply once a company is in genuine financial distress differ by jurisdiction.

The three insolvency grounds under German law

German insolvency law — the Insolvenzordnung (InsO), Germany’s insolvency code — recognises three triggers that can open insolvency proceedings against a GmbH, with very different consequences for the managing directors:

• Actual insolvency (§ 17 InsO). The company is unable to meet its payment obligations as they fall due. The law generally presumes actual insolvency once a company has stopped paying. It is by far the most common ground in practice — and it is the one that triggers the duty to file.
• Imminent insolvency (§ 18 InsO). The company will probably be unable to meet its existing payment obligations once they fall due; the forecast period applied is, in most cases, 24 months. It entitles the company to file, but does not require it — and it opens the door to preventive restructuring tools at the same time.
• Over-indebtedness (§ 19 InsO). The company’s assets no longer cover its liabilities, unless continuing the business over the next twelve months is predominantly likely (a positive going-concern forecast). Over-indebtedness also triggers the duty to file.

The crucial distinction is between profit and cash: a GmbH can show black figures in its management accounts and still become insolvent — a healthy P&L does not protect against an empty account. The causes are almost always a matter of timing: receivables arrive later than planned, capital sits tied up in stock or work in progress, or a large payment falls due before the matching receipt comes in.

Directors’ duties: deadlines and liability

Once actual insolvency or over-indebtedness has occurred, a tight statutory framework applies to the managing directors:

• Duty to file (§ 15a InsO). The insolvency filing must be made without undue delay — at the latest three weeks after actual insolvency occurs, or six weeks after over-indebtedness occurs. These deadlines are maximum periods for a realistic restructuring effort, not waiting periods: if it becomes clear earlier that restructuring will not succeed in time, the filing must be made sooner. Filing late is a criminal offence and creates personal liability risk.
• Payment restrictions (§ 15b InsO). Once insolvency maturity has occurred, payments out of company assets are generally prohibited; what remains permitted is essentially limited to payments consistent with the diligence of a prudent business leader — for example, to keep the business running for the proceedings. A director can be held personally liable for payments made in breach of this rule.
• Continuous crisis monitoring (§ 1 StaRUG). Independent of any acute crisis, German law requires the management of limited-liability companies to continuously monitor developments that could threaten the company’s survival and to take countermeasures in good time. A well-maintained cash flow outlook is the natural tool for meeting — and documenting — that duty.

In practice, this means that from the moment a serious squeeze becomes visible, documentation matters as much as the cash itself — who knew what numbers when, and which measures were taken. A week-by-week, continuously updated cash flow forecast is the most defensible evidence of that.

Cash flow shortage or actual insolvency? A worked example

Not every squeeze is insolvency. What matters is whether the gap is temporary and closes again quickly. If a large customer payment lands a few days after payroll is due, the gap in between is a cash flow shortage — uncomfortable, but bridgeable. If the gap persists, or the expected receipt keeps slipping further out, the position becomes serious.

German case law has developed a rule of thumb for drawing that line: a merely minor liquidity gap — as a rough guide, under ten percent of the obligations due — that is expected to close within roughly three weeks still points to a temporary stoppage; a larger or longer-lasting gap points to actual insolvency.

A generic example (illustrative values only): if €500,000 is due and €30,000 of that is missing but is confirmed to arrive within two weeks, a temporary stoppage looks likely. If €120,000 is missing with no confirmed receipt in sight, the position has to be assessed differently. That calculation — payment obligations due against available funds and confirmed receipts, week by week — is, at its core, exactly what a cash flow forecast does. The legal assessment of the result belongs with qualified advice; the earlier that advice is brought in, the better.

A simplified example of what the week-by-week view can reveal (generic illustrative values, not real figures):

On a monthly view this pattern looks unremarkable — a surplus overall. Only the weekly view shows the company slipping below zero in Week 2. See that three weeks ahead and there is room to act: bring a receipt forward, delay a payment, talk to the bank about the line. See it only on the bank statement, and the options — and possibly running deadlines — are already gone.

Immediate steps when the shortfall is real

Once a serious squeeze is in view, sequence and speed matter:

• Create transparency. Build a current 13-week outlook and a bank mirror across every account and line — based on real open items, not a gut feeling. That is also the foundation for every conversation with the bank and with advisors. To get a first, one-off read on the coming weeks without setting up ongoing software, the free 13-week forecast generator only needs two CSV exports and the current bank balance.
• Activate receivables. Chase due and overdue invoices consistently; take deposits and part-payments wherever the contract allows.
• Control outflows. Renegotiate payment terms with suppliers; stop or defer spending that is not business-critical.
• Talk to the bank — with numbers. A clean bank mirror and a defensible outlook are the difference between “we have a problem” and “we have a problem and a plan.”
• Document everything. Record the figures, the assumptions and the measures taken in writing — if it comes to it, that record is the evidence of having acted on the duty to monitor.
• Get advice early. Where insolvency is imminent, legal and restructuring advice belongs in the picture early — room to manoeuvre is greatest at the start, and the § 15a InsO deadlines run regardless of when you notice them.

What happens next: restructuring, the bank, and when you need a lawyer

Caught early, the paths forward stay open: short-term levers such as firm receivables collection and renegotiated payment terms (covered in the guide to cash flow shortage), a structured conversation with the bank about lines and bridging — see negotiating a credit line — and, where insolvency is only imminent rather than actual, the preventive restructuring tools the StaRUG opens up, discussed in the guide to imminent insolvency under German law. Every one of these paths needs the same entry ticket: current, defensible numbers.

Once actual insolvency has occurred, however, there is no way around legal involvement — at that point it is about filing on time and limiting the personal liability risk for the managing directors. Here too, a well-maintained weekly outlook puts you in a different negotiating position than starting to run the numbers only now.
