Your Landlord Never Sent a Nebenkostenabrechnung? There's a Real Deadline, and It Actually Works in Your Favor
A Nebenkostenabrechnung, also called a Betriebskostenabrechnung, is the annual statement your landlord sends reconciling the actual costs of running your building, heating, water, trash collection, building maintenance, and similar shared expenses, against the monthly advance payments (Vorauszahlungen) you've already made. Under § 556 BGB, your landlord genuinely has to deliver this statement to you by the end of the twelfth month after the billing period ends, this is a real, legally binding deadline, not a soft target. If your landlord misses it, the consequence actually favors you: they lose the right to demand any additional payment (Nachforderung) you might otherwise owe, unless they can prove the delay genuinely wasn't their fault, and the burden of proving that sits with them, not you. Importantly, this deadline cuts only one way: if the reconciliation shows you're actually owed a credit (Guthaben) because your advance payments exceeded the real costs, your landlord still has to pay that out regardless of how late the statement arrives, the missed deadline doesn't erase money owed to you.
The Official Rule
Understanding what a Nebenkostenabrechnung actually is, and specifically what happens when your landlord is late with it, changes an annual paperwork anxiety into something you can genuinely track and rely on.
A Nebenkostenabrechnung, sometimes called a Betriebskostenabrechnung, is the annual reconciliation of your building’s actual shared running costs, heating, water, trash collection, building maintenance, and similar expenses, against the monthly advance payments you’ve already been making. This is a real accounting exercise, not just a bill, it either results in you owing an additional payment or being owed a credit, depending on whether your advance payments matched the real costs.
| Situation | What happens |
|---|---|
| Landlord delivers statement within 12 months | Normal reconciliation, either party may owe the other |
| Landlord misses the 12-month deadline | Landlord loses the right to demand additional payment from you |
| Landlord proves the delay genuinely wasn't their fault | Exception applies, landlord can still claim the Nachforderung |
| You're owed a credit (Guthaben) | Still owed to you regardless of how late the statement arrives |
Under § 556 BGB, this deadline is genuinely legally binding: your landlord has to deliver the statement to you by the end of the twelfth month after the billing period ends. This isn’t a soft, best-practice target, it’s a statutory deadline with a real, specific consequence attached when it’s missed.
If your landlord misses this deadline, the consequence actually works in your favor: they lose the right to demand any additional payment (Nachforderung) you might otherwise owe for that billing period. This is a real, meaningful protection, not a technicality, a landlord who’s simply disorganized or slow about sending statements can genuinely forfeit their claim to money you’d otherwise owe.
There’s a real exception worth understanding honestly: if the landlord can prove the delay genuinely wasn’t their fault, they can still claim the Nachforderung despite the missed deadline. The critical detail here is where the burden of proof sits. It’s on your landlord to demonstrate this, not on you to prove they were simply late through their own fault, this default in your favor is a real, practical protection.
The deadline cuts only one way, and it’s worth being clear-eyed about this rather than assuming full symmetry. If the reconciliation actually shows you’re owed a credit because your advance payments exceeded the real costs, your landlord still has to pay that out regardless of how late the statement arrives. A missed deadline doesn’t let a landlord simply keep money that’s genuinely yours, it only limits their ability to collect more from you.
What Real People Say
Tenants navigating a genuinely late Nebenkostenabrechnung consistently describe initial uncertainty about whether they still owed money regardless of the delay, several mention real relief at learning the 12-month rule exists specifically to protect against open-ended financial exposure from a landlord’s slow paperwork.
Tenancy law resources describing this rule consistently emphasize the burden-of-proof detail as the part worth remembering specifically, since landlords sometimes assert a delay “wasn’t their fault” without actually being able to substantiate it, and tenants who understand this default is in their favor are better positioned to push back on an unsupported claim.
Step by Step
- Note the exact end date of your billing period (Abrechnungszeitraum), this is what starts the 12-month clock, not the date you moved in or any other date.
- If 12 months pass without a statement, know that your landlord has genuinely lost the right to demand additional payment from you for that period, barring a proven exception.
- If your landlord claims the delay wasn’t their fault, ask for actual documentation, the burden of proof is on them, not you.
- If you believe you’re owed a credit, pursue that regardless of how late the statement is, the 12-month rule doesn’t protect a landlord from paying out money that’s genuinely yours.
- Keep a simple record of your billing period dates and any correspondence, this makes the deadline easy to verify if a dispute ever comes up.

FAQ & Common Pitfalls
It's been over a year since our billing period ended and we still haven't received a statement. Does that mean we're just off the hook for any extra payment?
Genuinely, in most cases yes, this is exactly what the 12-month deadline is designed to protect you from. Once that period passes, your landlord loses the right to demand a Nachforderung from you for that billing period, unless they can prove the delay genuinely wasn't their own fault, and that's a real burden they have to meet, not something you need to disprove yourself.
What if our landlord says the delay was due to their property management company being slow, not their own fault?
This is exactly the kind of situation where the exception could genuinely apply, but the legal standard is specifically about the landlord's own fault, and courts have generally held landlords responsible for delays caused by people or companies working on their behalf, like a property manager. It's worth taking this claim seriously enough to ask for actual documentation rather than accepting it at face value, since the burden of proof is on your landlord either way.
We think we're actually owed money back, not owing anything. Does the 12-month rule protect us the same way?
No, and this is a genuinely important distinction to understand. The 12-month rule specifically limits your landlord's right to demand additional payment from you, it doesn't work the other way around. If your advance payments exceeded the real costs, you're still owed that credit regardless of how late the statement arrives, a delayed accounting doesn't let your landlord simply keep money that's genuinely yours.
