Missouri Security Deposit
Return Calculator

Missouri limits security deposits to 2 months’ rent and requires landlords to return the deposit within 30 days after a tenant moves out. The state does not require landlords to pay interest on security deposits.

These rules are established by Mo. Rev.

Stat. § 535.300.

Landlords who miss the 30 days return window or make unsupported deductions face penalties: tenant may recover up to double the wrongfully withheld deposit. Both tenants disputing withheld funds and landlords defending deductions benefit from knowing exactly what Missouri law allows and requires.

Missouri's Security Deposit Act (Mo. Rev.

Stat. § 535.300) allows up to 2 months' rent.

Missouri's double-damage penalty applies to 'wrongfully withheld' deposits — courts have interpreted this to require some element of bad faith or unreasonableness. Kansas City and St.

Louis do not have local rent control ordinances that modify state deposit rules, though both cities have active tenant advocacy organizations. Missouri's small claims limit is $5,000.

Missouri courts have held that landlords cannot charge for interior painting after tenancies of 3 or more years unless specific lease language makes painting a tenant obligation. Pet deposits are commonly collected separately but must stay within the 2-month aggregate cap.

Service animals are exempt from pet deposits.

Under Mo. Rev.

Stat. § 535.300, Missouri limits security deposits to 2 months’ rent.

This cap applies to the security deposit itself and typically does not include last month's rent, pet deposits, or other fees that may be collected separately under Missouri law. Landlords who collect more than the statutory maximum may be required to reimbursement the excess and could face additional penalties.

The deposit limit in Missouri is designed to prevent landlords from demanding excessive upfront payments that create barriers to housing access. For a rental with monthly rent of $1,500, the maximum security deposit under Missouri law would be calculated based on the 2 months’ rent formula.

Tenants should verify that the total amount collected at move-in does not exceed the statutory cap, and should request a receipt documenting the deposit amount, the date paid, and the account where the deposit is held.

Missouri tenants should be aware that security deposits are separate from other move-in costs. Application fees, pet fees, cleaning deposits, and last month's rent are distinct charges that may or may not be subject to separate regulations.

Read your lease carefully to understand exactly what each payment covers and whether it is reimbursable.

Missouri law requires landlords to return security deposits within 30 days after the tenant vacates the rental unit. This deadline is strict — this is roughly in line with the national average for deposit return deadlines.

The clock typically starts when the tenant surrenders possession of the unit and returns all keys.

Along with the deposit (or any remaining balance after deductions), the landlord must provide an itemized written statement listing each deduction. Missouri law specifically requires this itemization, and failure to provide it within the statutory window can result in the landlord forfeiting the right to retain any portion of the deposit.

Each deduction must be documented — vague entries like "cleaning" or "damages" without specifics are generally insufficient.

To protect your rights as a tenant in Missouri, always provide your landlord with a forwarding address in writing when you move out. Some states require the forwarding address before the return deadline begins to run.

Take date-stamped photos or video of the unit at both move-in and move-out to document the property's condition. If the landlord fails to return the deposit or provide an itemization within 30 days, send a written demand letter via certified mail before pursuing legal action.

Under Missouri law, landlords may deduct from the security deposit for the following: unpaid rent, damage beyond normal wear and tear. These deductions must be reasonable, documented, and itemized in the statement provided to the tenant.

Landlords cannot deduct for normal wear and tear — this is a critical distinction that is frequently disputed between landlords and tenants.

Normal wear and tear in Missouri generally includes minor scuffs on walls, worn carpet from everyday foot traffic, small nail holes from hanging pictures, faded paint due to sunlight exposure, and minor door or window wear. Damage beyond normal wear includes large holes in walls, stained or burned carpet, broken windows, unauthorized modifications, pet damage, and excessive filth requiring professional cleaning.

The line between wear and damage is not always clear, which is why move-in and move-out condition documentation is critical.

While Missouri does not require a formal walk-through inspection before move-out, tenants can request one. A pre-move-out inspection gives you the chance to fix any issues the landlord identifies, potentially saving deductions from your deposit.

Even without a formal requirement, conducting your own thorough inspection with date-stamped photos on the day you move out creates a strong evidence trail if you need to dispute deductions later.

Missouri does not require landlords to pay interest on security deposits. No interest requirement.

This places Missouri in the majority — only 14 of 51 jurisdictions require deposit interest. While tenants do not earn interest on their deposits in Missouri, they still have full rights to the return of the principal amount, less any lawful deductions.

Even without an interest requirement, Missouri tenants should be aware that their deposit money is being held for the duration of the lease. This represents a real opportunity cost, particularly for larger deposits.

When negotiating a lease in Missouri, consider whether the deposit amount is reasonable relative to the monthly rent and whether any of the upfront costs can be reduced.

Missouri does not require landlords to hold security deposits in a separate or escrow account. This means a landlord may commingle the deposit with personal or business funds, which carries some risk for tenants if the landlord faces financial difficulties.

Approximately 16 jurisdictions require separate accounts for deposit funds. Missouri tenants may want to ask their landlord where the deposit is being held, even though disclosure is not always required by law.

The penalties for security deposit violations in Missouri are significant. Under Mo.

Rev. Stat.

§ 535.300: tenant may recover up to double the wrongfully withheld deposit. These penalties apply when a landlord fails to return the deposit within the statutory deadline, makes improper deductions, or fails to provide the required itemized statement.

Missouri's double-damages provision means that a landlord who wrongfully withholds a $2,000 security deposit could owe $4,000 to the tenant, plus any attorney fees and court costs awarded. This penalty applies when the landlord's withholding is found to be willful or in bad faith — an honest mistake in calculating deductions may not trigger the penalty multiplier, but failing to return the deposit at all almost certainly will.

To pursue a security deposit claim in Missouri, tenants typically file in small claims court, which handles disputes up to a specified dollar amount without requiring an attorney. The process involves filing a complaint, paying a small filing fee, and presenting evidence at a hearing.

Key evidence includes the lease, proof of deposit payment, move-in and move-out photos, the landlord's itemized deductions statement (or lack thereof), and any correspondence about the deposit. Many Missouri courts also offer mediation services that can resolve deposit disputes faster than a full hearing.
