Mo. Rev. Stat. §535.300 30-Day Deadline Auto-Calc Refund Free PDF

A Missouri security deposit return letter is the written accounting a landlord must deliver after a tenant moves out. Under Mo. Rev. Stat. §535.300, the landlord has thirty days from the termination of the tenancy to return the full deposit or furnish a written itemized list of the damages withheld, together with the balance. Missouri caps the deposit at two months’ rent, gives the tenant a right to be present at the move-out inspection, and lets a wronged tenant recover twice the amount wrongfully withheld. The generator below does the arithmetic for you: enter the deposit and each line-item deduction, and it totals them, subtracts, and prints a ready-to-send letter. Confirm the current statute text at the Missouri Revisor of Statutes before you mail it.

The return letter is one equation wrapped in a legal deadline. You begin with the original security deposit the tenant paid — which in Missouri may not have exceeded two months’ rent when it was collected under Mo. Rev. Stat. §535.300(1). If the lease or a local rule required you to pay interest, you add that too, because it is legally the tenant’s money. From that combined figure you subtract every lawful deduction, each listed on its own line with a description and a dollar amount. What remains is the refund you enclose. If the deductions add up to more than the deposit, the equation goes negative and the letter instead shows the balance the tenant owes you.

What makes Missouri distinctive is the thirty-day clock in subsection 3 paired with the inspection right in subsection 5. The landlord must furnish the itemized list or the full refund within thirty days of the tenancy’s termination, and before withholding anything the landlord must give the tenant reasonable written notice of the inspection so the tenant can be present. Miss either step and a withheld amount can become wrongful, exposing the landlord to twice that amount. The generator on this page handles the money side flawlessly: it sums the deduction lines as you type, subtracts, and prints matching numbers into the PDF, so the arithmetic on the page and on the letter never disagree.

Fill in the parties, the deposit and any interest, and one line for each deduction. As you type, the calculator at the bottom updates in real time; when you click generate, the same totals are written into a formatted Missouri return letter you can print, sign, and mail. Every field below reaches the document, and the refund or balance is computed for you under Mo. Rev. Stat. §535.300.

Missouri’s entire security deposit framework lives in a single statute, Mo. Rev. Stat. §535.300, and every landlord who holds a residential deposit is bound by it. The section opens in subsection 1 by capping the deposit a landlord may demand or receive at two months’ rent. Subsection 2 defines the security deposit and confirms it remains the tenant’s money held in trust rather than the landlord’s to spend. The operative deadline sits in subsection 3: within thirty days after the tenancy terminates, the landlord must either return the full deposit or furnish the tenant a written itemized list of the damages withheld, along with the balance of the deposit.

Subsection 4 is the deduction list, and it is narrow by design. A Missouri landlord may withhold from the deposit only for three reasons: to remedy the tenant’s default in the payment of rent; to restore the dwelling unit to its condition at the commencement of the tenancy, with ordinary wear and tear expressly excepted; and to compensate the landlord for actual damages sustained because the tenant failed to give adequate notice of termination. Anything outside those three categories — and any charge for ordinary wear — is not a permitted deduction. Subsection 5 adds the inspection right: the landlord must give the tenant reasonable written notice of the date and time of the move-out inspection, and the tenant has the right to be present. Subsection 6 supplies the teeth: a landlord who wrongfully withholds all or any portion of the deposit is liable to the tenant for twice the amount wrongfully withheld.

The line between a lawful Missouri deduction and an unlawful one is the difference between damage and ordinary wear and tear. Subsection 4 authorizes only the cost of restoring the unit to its move-in condition, wear excepted — not upgrades, not routine turnover cleaning, and not the aging that happens even when a tenant is careful. The federal Department of Housing and Urban Development describes ordinary wear and tear as the deterioration that results from the intended, ordinary use of a dwelling; damage, by contrast, is harm from negligence, carelessness, accident, or abuse. Only the second category may come out of a Missouri deposit.

A useful test is to ask whether the condition came from living in the unit or from misusing it. Carpet flattened along the path from the door to the sofa is wear; the same carpet with a bleach stain is damage. Missouri courts, like courts elsewhere, also respect the depreciation idea behind HUD’s life-expectancy tables: if a carpet’s useful life is seven years and the tenant lived there five, the landlord cannot bill for a brand-new carpet, because most of that value was already used up by ordinary aging. When a line item is close to the wear-and-tear boundary, deduct conservatively and document thoroughly — an over-aggressive itemization is the fastest route to the subsection 6 penalty.

It helps to watch the equation run once with real numbers under Missouri law. Suppose a tenant paid a security deposit of fifteen hundred dollars — well within the two-month cap for a unit renting at a thousand dollars a month — and the lease did not require interest, so the interest field stays at zero. The starting pool the landlord is accounting for is therefore fifteen hundred dollars, all of it the tenant’s money held under §535.300.

At the move-out inspection, which the landlord noticed in writing and the tenant attended, the landlord finds three chargeable items. The tenant left one month of rent unpaid, which the lease pegs at nine hundred fifty dollars. A dog left urine stains that required professional carpet treatment, invoiced at two hundred eighty dollars. And a bedroom wall had several fist-sized holes that cost one hundred twenty dollars to patch and repaint. Faded paint elsewhere and a worn path in the hallway carpet were left off the list entirely, because those are ordinary wear and tear and charging for them would convert a lawful itemization into a wrongful withholding.

The three lawful deductions total thirteen hundred fifty dollars. Subtracting that from the fifteen-hundred-dollar deposit leaves a refund of one hundred fifty dollars owed back to the tenant, which the landlord encloses with the letter and mails within thirty days. Had the damage been worse — say a ruined subfloor pushing deductions past the deposit — the equation would have gone negative, and the letter would instead show a balance the tenant owes, with the same line-item detail and receipts behind it. The generator above produces exactly this arithmetic, whichever way it lands, and prints the matching figures into the PDF so the page and the letter never disagree.

Missouri gives the tenant a statutory role in the move-out inspection that many landlords overlook. Under §535.300(5), before withholding any part of the deposit the landlord must give the tenant, or the tenant’s representative, reasonable written notice of the date and time the landlord will inspect the unit to determine what to withhold, and the inspection must be held at a reasonable time. The tenant then has the right to be present at that inspection. The notice can be delivered in person or sent to the tenant’s last known address.

This is not a formality. An inspection the tenant could attend produces a shared record of the unit’s condition, which is exactly the kind of contemporaneous evidence that carries weight if a deduction is later challenged. A landlord who skips the written notice, or who inspects at an unreasonable hour with no chance for the tenant to appear, weakens the defense of every deduction that follows. Pair the inspection with a completed move-in and move-out inspection checklist and dated photographs so each line on the return letter can be tied back to a documented change in condition.

A Missouri tenant who believes the itemization is wrong or the deposit was kept without cause is not without recourse. The everyday forum is small claims court, where deposit disputes are among the most common cases and where a tenant usually does not need a lawyer. What raises the stakes for a careless landlord is subsection 6: if the landlord wrongfully withholds all or any portion of the deposit in violation of the section, the tenant recovers as damages twice the amount wrongfully withheld.

Note the precise contours of that remedy. The multiplier applies to the portion wrongfully withheld, not to the entire deposit, so a landlord who correctly deducts nine hundred fifty dollars of unpaid rent but wrongly tacks on a two-hundred-dollar wear-and-tear charge faces double damages on the two hundred, not the whole sum. And unlike some states, the Missouri deposit statute as written does not add a separate award of attorney fees in this section — the doubling is the statutory penalty. Because the exact application turns on the facts, a tenant weighing a claim, or a landlord assessing exposure, should read the current text at the Missouri Revisor and consult the broader Missouri landlord-tenant laws.

Most Missouri deposit disputes trace back to a short list of avoidable errors. Reviewing them before you mail the letter is the cheapest insurance available.

Two refinements separate a rushed Missouri return letter from a defensible one. The first is interest. Unlike a number of states, the Missouri statute does not require a landlord to pay interest on a residential security deposit, so for most Missouri tenancies the interest field on this form stays at zero. Where a written lease term or a local ordinance nonetheless promises interest, that promise is enforceable as a matter of contract or local law, and you would add the accrued interest to the deposit before subtracting deductions. When in doubt, treat interest as owed only if a document you signed or a local rule says so.

The second refinement is prorating for an item’s age. A Missouri landlord cannot bill a departing tenant the full price of a brand-new replacement for something already partway through its useful life, because subsection 4 authorizes only restoration to the move-in condition, not betterment. HUD’s life-expectancy guidance is the common reference point: interior paint is often treated as lasting two or three years, plush carpet roughly five to seven, and larger appliances closer to ten. If a carpet with a seven-year life is damaged after five years of tenancy, only the remaining fraction of its value is fairly chargeable. Applying that proration signals good faith and keeps a deduction proportionate if the tenant challenges it in small claims court.

Security deposit return rules vary widely from state to state, and Missouri sits in the middle of the pack on timing while carrying a sharper-than-average penalty. The thirty-day deadline is common, but some neighboring states run shorter or longer clocks, and several set a different window when there are no deductions than when there are. What distinguishes Missouri is the combination of a firm thirty-day rule, the tenant’s statutory inspection right, and the double-damages remedy for wrongful withholding — a package that rewards a careful landlord and punishes a sloppy one.

• Calendar the thirty days. Count from the date the tenancy terminated and mail well before day thirty, with proof.
• Give written inspection notice. Subsection 5 requires it; a tenant who could attend is far less likely to dispute the result.
• Deduct only within subsection 4. Unpaid rent, restoration to move-in condition, and damages from inadequate notice — nothing else.
• Photograph at move-in and move-out. Dated photos next to the inspection checklist turn “your word against mine” into documented fact.
• Itemize line by line. One description and one amount per deduction, never a single lump sum, and attach the receipt.
• Respect the item’s life expectancy. Prorate for age rather than charging full replacement cost on a used item.
• Mail to the last known address. Certified mail with a return receipt gives you provable timing and delivery.
• Keep a copy. Retain the signed letter, the receipts, and the mailing proof in the tenant’s file.
