How long does a landlord have to return a security deposit in Missouri?
In Missouri, the deadline is 30 days after move-out. That clock runs from move-out and the return of possession, not from the end of the lease.
Missouri law sets the maximum deposit at 2 months' rent.
Missing the deadline has teeth. Across states, remedies range from losing the right to any deduction to penalty damages plus the tenant's attorney's fees. The itemized deduction statement has to arrive inside the same window to preserve any deduction at all.
