Czech rental deposit: limit, interest and return

You may be deciding whether to pay a two-month deposit, calculating interest after several years, or waiting for money after handing back the keys. Treat these as one evidence chain: what was agreed, how the statutory cap was calculated, when and to whom you paid, what happened during the tenancy, when it ended, which deductions are proved, and which principal and interest remain.

This guide is for a direct apartment lease. If you contracted with a tenant or cooperative member rather than the owner, use the sublease-deposit recovery guide before relying on the Section 2254 cap or interest rule.

What the deposit is — and is not

A rental deposit secures obligations arising from the tenancy. Government guidance says the deposit and agreed contractual penalties together may not exceed three times the monthly base rent; service payments are not included in that ceiling. The money is not automatically the landlord’s final month of rent, and it is not a general renovation budget.

Before paying: verify the cap and the paper trail

• Find the exact deposit clause and the obligation it secures.
• Use base rent without service advances when checking the three-rent ceiling.
• Add every agreed contractual penalty to the deposit before testing that combined ceiling.
• Confirm the recipient, bank account and how an agency or reservation payment will be credited.
• Pay by traceable transfer or obtain a signed receipt stating amount, date, apartment and purpose.
• Write down the interest rule, return event, permitted set-off and method for documenting deductions.

Do not silently treat the deposit as the last month’s rent. Unless the parties agree to that settlement, rent and the security remain separate obligations. Also distinguish a landlord deposit from an agency reservation fee or commission; sending several payments to one account does not give them the same legal purpose.

What may be deducted?

• Unpaid rent or service obligations that are actually due.
• Proven damage beyond ordinary wear, with a defensible cost.
• Other due obligations that the deposit validly secured.

Ask for an itemised calculation, not only a rounded total. For damage, compare the move-in and move-out records, the age and original condition of the item, invoices or estimates, and whether the issue is ordinary wear. Replacing an old item with a new one does not automatically make the entire new purchase price a fair deduction. For a painter or wall claim, use the room-by-room painting evidence guide.

If the tenant is still in the apartment and the arrears are growing, do not treat the deposit as a substitute for the required notices. The unpaid-rent landlord timeline separates the debt ledger, repayment demand, termination and 2026 eviction order.

When should the deposit be returned?

Civil Code Section 2254 says the landlord returns the security when the tenancy ends and sets off what the tenant then owes. The current Ministry for Regional Development guidance says the same; it does not create a general statutory 30-day grace period. Record separately when the legal tenancy ended, when the apartment and keys were handed over, and any different contractual settlement term.

A future annual service statement does not by itself explain holding the whole deposit for months. Ask which existing or reasonably identified obligation is being set off, the amount retained for it, its evidence, and when the unused balance will be paid. A disputed contract clause or unusual chronology needs individual review rather than a guessed universal deadline.

Do not forget interest

Section 2254 gives the tenant interest on the deposit from payment until return, at least at the statutory rate. Government guidance says the rate may be agreed but cannot remove the minimum entitlement; a clause denying all interest is described as invalid. The fallback rate can be legally and factually disputed, so do not copy a percentage from a generic calculator without recording the lease date, deposit date, amount, agreed clause and source of the rate.

Deposit interest compensates for holding the security during the tenancy. Interest for late payment after the balance became due is a separate question. Keep principal, deposit interest, accepted deductions and any default claim on separate lines so one uncertain rate does not hide the undisputed balance.

Send one complete written demand

• Identify the lease, apartment, deposit amount, and payment date.
• State the tenancy-end and key-handover dates.
• List any deductions you accept and expressly dispute the others.
• Request an itemised calculation and supporting documents.
• Give the bank account and a clear response and payment deadline.
• Request the remaining deposit plus applicable interest.
• Send it in a form whose content and delivery you can later prove.

If the landlord still does not pay

Preserve the demand and proof of delivery. The ministry’s guide recommends a written request first and identifies a court claim as the next route when the landlord does not respond. Before litigation, have the amount, evidence, limitation period, interest, and likely costs checked for your specific case.

If withholding the deposit followed a disputed termination, also review whether the termination notice and its deadlines were valid. Keep the two disputes in one chronology but calculate them separately.

Build the evidence from day one

• Pay by traceable transfer and label the payment clearly.
• Use a detailed handover report with meters, keys, defects, and equipment.
• Take dated photos before moving belongings in.
• Record every repair request and the landlord’s response.
• Repeat the same evidence process at move-out.
