Moving out does not always end the accounting between a tenant and landlord on the handover date. A landlord may still need to prepare an annual statement for operating costs such as heating, water or building services. In some circumstances, a limited part of a rental deposit can secure an expected extra payment while that statement is pending. That is different from a landlord keeping an unexplained amount indefinitely or treating every future bill as a proven debt.
If your landlord says they are holding money for utilities, first find out what the amount represents. Is it a final charge from a statement you have already received? A temporary reserve for a statement that is not due yet? Or a deduction for damage or another claim? Those categories have different records and timing. A handover protocol marked “all good” can help with a damage dispute, but it does not itself settle an annual utility account.
Ask what the retained amount is for
Write to the landlord or property manager and ask for a clear breakdown. Identify the amount, the date it was retained or deducted, the billing period, the contractual basis, the actual or estimated calculation, and whether a formal operating-cost statement has been issued. If the explanation refers to more than one year, ask that each year and amount be listed separately.
This matters because the story may change as details are clarified. “They deducted €300” could mean a final charge for repairs, a reserve against an expected 2025 utility balance, a separate amount for 2026, or a temporary total that combines different items. Do not assume that a number mentioned in an online comment or informal conversation accurately describes the landlord’s accounting. Ask for the landlord’s own written explanation and supporting documents.
Keep your request factual and easy to answer. For example:
Please identify how the €300 retained from my deposit has been allocated. For each amount, please state whether it is a final charge or a provisional reserve, the relevant billing period, the lease provision relied on, the calculation and the expected date of the operating-cost statement. If a statement has already been prepared, please send it and explain how the amount was calculated. I would also like to arrange inspection of the underlying records under BGB § 556(4).
This is a practical information request, not a formal legal notice or a guarantee that the landlord must use these exact words in a reply. Keep a copy and proof of delivery.
When may an amount remain reserved for operating costs?
Under BGB § 556(1)–(2), a residential lease can provide that the tenant bears operating costs, and the parties may agree to a flat amount or advance payments. Advances must be reasonable. A landlord cannot make a charge recoverable merely by calling it a utility cost; the lease and the nature of the expense still matter.
Where the tenant pays advances, § 556(3) requires an annual statement. The landlord must deliver it by the end of the twelfth month after the accounting period ends. If the landlord seeks an additional payment after that deadline, the demand is generally excluded unless the landlord was not responsible for the late delivery. The statute also says a landlord is not required to prepare partial statements. So the expected timing is measured from the end of the billing period, not automatically from the day you moved out.
The Federal Court of Justice has recognized that a rental deposit may secure an operating-cost balance that is not yet due. In its decision of 18 January 2006, BGH VIII ZR 71/05, the Court’s published headnote states that a landlord may retain an appropriate part of a deposit until the applicable accounting deadline if an additional payment is expected. The Court's reasoning ties that security to the deposit agreement, so check whether the lease limits what the deposit secures. The important limits are “appropriate part” and “if an additional payment is expected.” The decision does not authorize an arbitrary hold, establish a standard euro amount, or create a fixed return date for every deposit.
That distinction is especially important where the tenant previously received a utility refund. A past credit may be relevant when asking why the landlord expects a new balance and how much is reasonably tied to it. But one earlier refund does not automatically prove that there can be no later additional charge: costs, advances, occupancy, the billing period and allocation can change. Ask for the evidence behind the expected amount rather than assuming either that the landlord is right or that the prior refund settles the issue.
Work out which deadline applies
Find the billing period in the lease or the previous statements. It may follow the calendar year, but do not assume that without checking. The statutory accounting deadline runs to the end of the twelfth month after the actual period ends.
For example, if the applicable billing period is January 1 to December 31, 2025, the ordinary deadline to deliver the statement is December 31, 2026. A landlord who has not sent the 2025 statement by then generally cannot make an additional demand afterward unless the landlord was not responsible for the delay. If the lease uses a different billing period, calculate from its end instead. This example does not decide whether any particular cost is recoverable or whether an exception applies.
The deadline for the statement is not a universal deadline for returning every euro of a deposit. Operating costs can be settled on their annual cycle, while other deposit claims are reviewed separately. The BGB does not give a single across-the-board number of months after move-out for the landlord to return a deposit. Avoid relying on blanket internet statements such as “all deposits must be returned within three months” or “the landlord can always wait six months.” Ask what specific claim remains open, why it remains open, and when the landlord expects to resolve it.
If the landlord has sent a statement
Once you receive the statement, check it as a document rather than comparing only the final total. Confirm:
- the billing period and the dates you occupied the apartment;
- which operating-cost categories are included and whether the lease allocates them to you;
- the allocation method or share used for the apartment;
- the total building costs and the amount assigned to your unit;
- the advances already credited to you; and
- whether the resulting balance is a credit or an additional payment.
Under BGB § 556(4), you may request access to the documents underlying the statement. Ask how and when you can inspect them. Keep the statement, the envelope or email showing when it arrived, and your inspection notes. The statute generally gives a tenant 12 months from receipt to raise objections; if you need time to review the records, record the receipt date and get advice before that period expires. The statutory exception applies when the tenant was not responsible for missing the deadline, so do not assume it automatically extends your time.
If there is no statement yet, ask for an estimate and the reason a further payment is expected. You can request the prior year’s statements and records of your advances as context. A landlord need not issue a partial annual account just because the tenancy ended, but a request for the period, basis and anticipated calculation helps clarify whether the retained amount is tied to a real upcoming balance.
Separate a utility reserve from damage or other deductions
A deposit can be connected to more than one kind of claim. Keep each one separate in your correspondence:
- Pending operating-cost statement: identify the billing period, the expected extra payment and the due date for the annual statement.
- Final operating-cost statement already issued: request the complete statement, check the allocation and advances, and ask to inspect supporting documents.
- Damage claim: request the specific damage, evidence, repair estimate or invoice, and the amount the landlord says is attributable to you.
- Rent or other unpaid amount: ask for the period, contractual basis and ledger showing how payments were credited.
A signed handover record and dated photographs are useful when the dispute concerns the apartment’s condition. Under BGB § 538, changes or deterioration caused by contractual use are not the tenant’s responsibility. But the protocol does not answer whether an annual operating-cost balance is due, and a clean record may not resolve damage that was not visible at handover. Keep the record, photographs, meter readings, keys receipt, final utility statements and messages together.
Do not agree that an unexplained amount is a final debt simply to obtain the rest of the deposit, and do not assume that a “reserve” label makes any sum valid. Ask the landlord to state their position in writing. If the landlord is claiming a balance from a statement, the document and its delivery date are important. If the amount is only provisional, ask what change or event will trigger the next review and the expected date of that review.
Organize a concise record before escalating
Build a short chronology with the lease start and end dates, the billing periods, monthly advances, prior statements, move-out date, handover, date the deposit accounting arrived, and each follow-up. A case chronology workflow explains a general way to organize dates and supporting records. If the lease is long, a contract data extraction guide can help locate the clauses on operating costs, advances, accounting periods, deposit security and notice. These are document-organization resources, not German legal advice.
Imagine a tenant who moved out in May, received a letter in October saying €300 would remain “for utilities,” and previously got a small refund for an earlier year. The tenant should first ask whether the €300 covers one billing period or several, whether a formal statement exists, and what amount the landlord expects beyond advances. If the billing period is the calendar year, the 2025 statement deadline is not determined by the May move-out; it follows the end of 2025. The earlier refund is useful comparison, but the tenant should not treat it as proof that the next year must also end in a credit. The landlord’s response and documents are needed to assess the amount.

When to get individual help
Consider contacting a local Mieterverein or a lawyer who handles German residential tenancy matters if the landlord refuses to identify the amount, the statement appears incomplete, a payment deadline is near, or a large balance is being withheld. Bring the lease and addenda, deposit proof, advance-payment records, past utility statements, the final statement if one exists, handover protocol, move-out evidence and your written request.

Gotham is a legal-workspace product, not a German tenants’ association or a substitute for a local adviser. The practical goal here is to make the landlord’s calculation, billing period and supporting records clear enough for you and a qualified adviser to assess the next step.
Questions to ask about a deposit hold
Before you accept the landlord’s explanation, try to get clear answers to these questions: Is the amount a provisional reserve or a final deduction? Which billing period does it cover? What additional payment is expected, and how was that estimate reached? When does the statutory accounting period end? Has a statement already been delivered, and when did you receive it? Are there separate damage, rent or other claims? Can you inspect the documents used to calculate the statement?
Keep all answers and attachments in one dated file. If the landlord provides a corrected statement later, preserve the earlier version too. If the amount is returned or offset, ask for a final itemization showing how the deposit was settled. That record will make it easier to distinguish an appropriate temporary reserve from a final charge that still needs explanation.
Questions about rental deposits and utility costs in Germany
Can a German landlord keep part of a deposit for a later utility bill?
The Federal Court of Justice has said an appropriate part may be retained until the operating-cost accounting deadline when an additional payment is expected. That does not automatically make any amount reasonable or resolve a particular tenancy; the lease, expected cost and records matter.
Is there a fixed deadline to return a Germany rental deposit?
The BGB does not set one universal deposit-return date. Operating-cost statements have their own deadline under § 556(3), while the landlord may need a fact-specific reasonable period to review other claims. Do not confuse those clocks.
When is a German operating-cost statement due?
For advances, BGB § 556(3) requires annual accounting and delivery by the end of the twelfth month after the billing period ends. A landlord's late additional demand is generally excluded unless the landlord was not responsible for the delay.
Can I ask for receipts behind the Nebenkostenabrechnung?
Yes. Under BGB § 556(4), the tenant may request access to the documents underlying the operating-cost statement. Ask in writing which records are available and how to inspect them.
Does a clean handover protocol mean the landlord must return the whole deposit?
It is useful evidence about the condition at handover, but it does not decide a later annual utility-cost statement. Ask whether each retained sum is a damage claim, an unpaid amount or a provisional operating-cost reserve, and request its calculation.
How long do I have to object to a German utility statement?
BGB § 556(3) generally gives the tenant 12 months after receiving the statement to raise objections, subject to the statutory exception for a tenant who was not responsible for the delay. Record the date received and get advice if the deadline is close.
General information about German residential tenancy accounting, not legal advice. Whether a landlord may retain a deposit amount depends on the lease, billing period, likely additional costs, documents and timing. Get advice from a German tenant association or tenancy lawyer before withholding rent, setting off an amount or starting a claim.
