Late Fees and Default Interest for Landlords in Baden-Württemberg

When a tenant fails to pay rent on time, landlords naturally want to recover not just the outstanding amount but also compensation for the delay. However, German law — primarily governed by the Bürgerliches Gesetzbuch (BGB), which has been in effect since 1 January 1900 — sets strict limits on what can be charged, particularly in residential tenancies. The US-style practice of flat "late fees" is largely unenforceable in Germany.

When Does Default Begin?

Under German law (§ 556b BGB), residential rent is due at the beginning of the month — specifically, no later than the third business day of the month. If the tenant fails to pay by this date, they are automatically in default (Verzug). Under § 286 Abs. 2 Nr. 1 BGB, no separate reminder or demand letter is required to trigger default — the calendar date alone is sufficient.

Default Interest in Residential Tenancies

Once the tenant is in default, the landlord is entitled to statutory default interest from the first day of default.

• The interest rate for residential tenancies (consumer transactions) is 5 percentage points above the current base rate (Basiszinssatz) as defined in § 247 BGB (§ 288 Abs. 1 BGB).
• The base rate changes semi-annually (January 1 and July 1), so the effective default interest fluctuates.
• Contractual agreements for higher interest rates in standard-form residential leases are generally void under § 307 BGB.

Calculation: Multiply the outstanding rent by the interest rate, divide by 365, and multiply by the number of days in default. For a €1,000 monthly rent, the daily default interest amount is typically in the single-digit cent range — making it a marginal deterrent at best.

Dunning Fees (Mahngebühren)

Flat late-fee penalties — common in the US (e.g., "$50 per late payment") — are not enforceable in German residential leases. Such clauses constitute an unreasonable disadvantage to the consumer and are void under standard terms (AGB) law (§ 307 BGB).

However, landlords may charge reasonable dunning fees as damages for the administrative cost of issuing reminders:

• Accepted amounts: Courts generally tolerate €2.50 to €3.00 per dunning letter (often only from the second reminder onward).
• What is not compensable: The landlord's personal time spent drafting the letter is not considered recoverable damages.
• Fees of €5, €10, or €20 per notice are regularly struck down as disproportionate.

Bank Charges for Failed Direct Debits

If the landlord collects rent via SEPA direct debit and the charge is returned due to insufficient funds, the bank typically charges the landlord a return fee (usually €3 to €5).

These actually incurred bank charges can be recovered from the tenant in full as damages, in addition to the postage cost for the notification letter.

Jurisdiction and Termination Rights

Landlords facing persistent non-payment should focus on their termination rights and the appropriate legal venue. Any lawsuit regarding residential tenancy must be brought before the local Amtsgericht (District Court) where the property is located, regardless of the value in dispute (§ 23 Nr. 2a GVG, § 29a ZPO).

• Extraordinary (immediate) termination is possible when the tenant is in arrears for two consecutive months or has accumulated total arrears equal to two months' rent (§ 543 Abs. 2 BGB).
• The statutory cure right (Schonfristzahlung) allows the tenant to void the extraordinary termination by paying in full within two months of being served — but this remedy is available only once every two years.

Automated Dunning with Landager

Stop calculating interest by hand. Landager syncs with your bank account, detects missing rent payments by the 4th business day of each month, and can automatically generate legally compliant payment reminders — complete with accurate default interest calculations. If arrears reach the termination threshold, the system flags the situation and drafts the extraordinary termination notice at the click of a button.
