Up to 2 months’ rent under Missouri law. A landlord may not demand or receive a security deposit greater than two months' rent (RSMo 535.300.1). The cap covers the security deposit itself. Nonrefundable fees and pet deposits can raise ongoing questions, so read your lease closely.
Return deadline
30 days
30 days after the tenancy ends. Enter your move-out date for the exact deadline.

These are the Missouri figures applied to what you entered: a plain summary of the rule and the dates, not a determination that anyone did or did not comply.

If a deposit is wrongly kept
If a landlord wrongfully withholds all or part of the deposit, the tenant may recover as damages twice the amount wrongfully withheld. Missouri courts treat the deadline strictly, with no grace period, so a late or missing itemization can trigger the double-damages exposure.
Interest on the deposit
Missouri does not require a landlord to pay interest on a security deposit. The statute is clear that any interest the deposit earns belongs to the landlord, not the tenant.
Local ordinances
The landlord must give the tenant written notice, at the last known address or in person, of the date and time of the move-out inspection, and the tenant has the right to be present at that inspection.

How Missouri security deposits work

Missouri caps a residential security deposit at two months' rent under RSMo 535.300, and it requires the landlord to hold that money for you in a bank, credit union, or federally insured depository institution rather than spending it. After your tenancy ends, the landlord has 30 days to either return the full deposit or send you a written itemized list of the damages being charged, along with whatever is left over. If the landlord wrongfully keeps any part of your deposit, you can recover twice the amount wrongfully withheld. One Missouri-specific step protects you at move-out: the landlord must give you written notice of the inspection date and time, and you have the right to be there. Any interest the deposit earns belongs to the landlord, and Missouri does not require the landlord to pay you interest.
