Security deposit — rules for charging and settlement

What is the maximum deposit?

Under the tenants' rights act, the deposit cannot exceed twelve times the monthly rent. In practice, 1–3 months' rent is most common.

When and how to return it?

The deposit must be returned within 30 days of the tenant vacating the property. You can deduct justified repair costs and payment arrears — but you must document them.

What can you deduct?

  • Repair costs beyond normal wear and tear
  • Rent and utility arrears
  • Costs of removing items left by the tenant
  • Cleaning costs if the apartment was returned in poor condition

Note: Normal wear and tear (minor marks on walls, natural floor ageing) does not justify deductions.

How to document deductions?

Each deduction must be supported by an invoice or receipt. Photos from the handover report are your main evidence. In SmartRentier, the deposit settlement generates a PDF with itemised deductions and the final amount to be returned.
