Deposit Return in Germany: What a Correct Kautionsabrechnung Looks Like

Why your deposit is being held — and why you deserve a proper accounting

You handed over roughly two to three months' rent when you moved in. You cleaned the flat, returned the keys, and now — weeks or months later — the money still hasn't landed in your account. Or worse, a smaller amount arrived with a vague note about "repairs" and nothing else.

If you moved to Germany to study or work, this is one of the most stressful parts of leaving a flat, precisely because the rules aren't obvious and the paperwork is in German. This guide explains, in plain terms, what you are actually entitled to, how long a landlord may take, what they may and may not deduct, and what a correct Kautionsabrechnung (deposit settlement statement) has to contain so you can check it line by line.

One honest note up front: this is general information, not legal advice. For a binding assessment of your specific contract, contact a local Mieterverein (tenants' association) or a lawyer specialising in tenancy law (Mietrecht).

What is a Kautionsabrechnung, exactly?

A Kautionsabrechnung is the landlord's written settlement of your security deposit: it states how much you paid, what (if anything) is being deducted, on what legal grounds, and how much is being paid back to you.

There is no single official form, but a proper statement is transparent and verifiable. Case law and tenant-law practice expect landlords to provide a detailed, itemised list of any claims — not a round number. If your landlord simply says "we kept €400 for cleaning and repairs," that is not a Kautionsabrechnung; it is an assertion you are entitled to challenge.

What a correct statement should contain

A settlement you can actually check should include:

• The original deposit amount paid, and how it was paid (in one sum or in the three legally permitted instalments).
• Any interest accrued — a cash deposit must be held in an account bearing the usual interest rate for savings with three months' notice, and that interest belongs to you (§ 551 (3) BGB).
• Each deduction listed separately, with a short reason (e.g. "unpaid utility balance," "repair of damaged worktop").
• Evidence for each deduction: invoices, cost estimates (Kostenvoranschläge), or the relevant line of the utility statement.
• The remaining balance paid out to you, and the date of payment.

If any of these are missing, ask for them in writing.

How much deposit could the landlord even keep?

Your deposit was legally limited from day one. Under § 551 BGB, a security deposit for a residential flat may not exceed three months' cold rent — the base rent without heating, water, or other service charges (Nebenkosten). Any contract clause demanding more than three months' cold rent is invalid for the excess.

The same rule gives you the right to pay the deposit in three equal monthly instalments: the first when the tenancy begins, the other two with the following two months' rent. Landlords must also keep the deposit separate from their own money, in a dedicated, insolvency-proof account (typically a Mietkautionskonto). This matters at move-out because the account should have earned interest that is added to your refund.

When must the deposit come back?

Here's the part that surprises most international tenants: German law sets no fixed 30-day deadline. Instead, the landlord is granted a "reasonable consideration period" (angemessene Überlegungsfrist) to inspect the flat and check for any claims.

In practice, German courts generally treat three to six months after the end of the tenancy as reasonable. Some rules of thumb:

• If the flat is handed back without defects and with no open debts, the deposit should be returned promptly — the Federal Court of Justice regards a few days as appropriate in clear cases.
• The landlord may hold back only the portion realistically needed to cover a specific expected cost, and must return the undisputed remainder without waiting.
• Holding the entire deposit for well over six months, with no justification, is generally unlawful and can expose the landlord to a claim for damages.

The utility-bill exception

There is one legitimate reason a small part of your deposit may be held longer: the annual utilities statement (Nebenkostenabrechnung). A landlord may retain a reasonable sum to cover a possible back-payment until the final utility bill is settled — but only that sum, not the whole deposit, and the rest must come back on the normal timeline.

What can a landlord legally deduct — and what not?

A landlord may only reach into your deposit for a concrete, provable claim against you. In practice, valid deductions fall into a few categories:

1. Unpaid rent you still owe.
2. Outstanding utility costs confirmed by the Nebenkostenabrechnung.
3. Damage beyond normal wear and tear that you demonstrably caused.
4. Valid cosmetic-repair (Schönheitsreparaturen) obligations — but only if the clause in your contract is legally effective.

Normal wear and tear is not chargeable

This is where many international tenants lose money they shouldn't. Normal wear and tear (normale Abnutzung) cannot be deducted. Faded paint after several years, minor scuffs on walls, small dents in carpet where furniture stood — these come with ordinary living and are covered by the rent, not the deposit. Only genuine damage — a burn in the countertop, a cracked sink, a hole drilled far beyond the ordinary — may be charged.

Many cosmetic-repair clauses are invalid

German landlords often try to shift painting and minor renovation onto the tenant. But the Federal Court of Justice (Bundesgerichtshof) has invalidated large numbers of these clauses. A cosmetic-repair clause is likely void if it:

• imposes a rigid time schedule (e.g. "repaint every three years regardless of condition");
• requires you to renovate even though the flat was handed to you unrenovated; or
• dictates the exact colour you must use.

If your clause is invalid, you owe nothing for cosmetic repairs — and any deduction on that basis can be challenged. When in doubt, have the clause read by a Mieterverein before you accept a deduction.

How do I check a Kautionsabrechnung line by line?

Use this quick checklist when a statement arrives:

• [ ] Does it show the full original deposit plus any interest?
• [ ] Is every deduction itemised with a reason — no lump sums?
• [ ] Is there an invoice or cost estimate for each repair charged?
• [ ] Are any deductions actually just normal wear and tear (not chargeable)?
• [ ] Is a cosmetic-repair charge based on a clause that is actually valid?
• [ ] Do the utility deductions match your Nebenkostenabrechnung?
• [ ] Was the flat's condition recorded in a handover protocol (Übergabeprotokoll) you both signed?

The handover protocol is your strongest evidence. If you documented the flat's condition (ideally with dated photos) at move-in and move-out, disputed "damage" is much harder to pin on you.

What if the landlord withholds the deposit without a proper statement?

If months pass with no money and no accounting, you can escalate step by step.

1. Send a written demand (Mahnung). Request the refund and the itemised statement, set a clear, reasonable deadline (e.g. 14 days), and send it by registered post (Einschreiben) so you can prove delivery. State that you will pursue legal steps if the deadline passes.
2. Get support from a Mieterverein. A local tenants' association can review your contract, draft further letters, and mediate. Membership typically costs in the region of €50–€100 per year and includes legal advice on tenancy matters.
3. Consider a court claim. As a last resort you can file a payment order (Mahnbescheid) or a claim at the local court (Amtsgericht). Legal-expenses insurance (Rechtsschutzversicherung) can cover the costs if you had it in place.

Remember the timing: claims from the tenancy are subject to a three-year limitation period (Verjährungsfrist). For a deposit, that period generally begins after the tenancy ends and the landlord's reasonable settlement window has passed — so don't wait indefinitely, but you are not out of time the day after month six.

Conclusion

Your deposit is your money, and German law is on your side: it caps the amount, requires interest, limits deductions to proven claims, and entitles you to a clear, itemised Kautionsabrechnung you can verify. The single most useful step is to check any statement line by line against your signed handover protocol and dated photos — and if a deduction doesn't hold up, put your demand in writing and take it to a local Mieterverein before you accept a cent less than you're owed.
