How long does a landlord have to return a security deposit in Oklahoma?

45 days. The clock does not start at move-out. It runs from the latest of three events — the tenancy terminating, possession being delivered, and a WRITTEN demand from the tenant — and the balance comes back without interest.

What happens if a landlord does not return the deposit on time in Oklahoma?

The civil remedy is a bare recovery of the deposit and any prepaid rent, with no statutory multiplier. Misappropriating escrowed deposit money is separately a crime, punishable by up to six months in county jail and a fine of up to twice the amount taken.

Do landlords have to pay interest on security deposits in Oklahoma?

No — Oklahoma does not require interest on the security deposit to be paid to the tenant. No interest is ever owed to the tenant. Section 115(B) expressly says the balance is returned 'without interest,' and the 6-month reversion clause frames the escrow cost as the landlord's consideration.

What are the security deposit rules in Oklahoma?

Verified October 2, 2026 All Oklahoma topics →

Oklahoma sets no cap on security deposits, but landlords must keep every deposit in an escrow account maintained in Oklahoma with a federally insured financial institution, and must return the balance, without interest, within 45 days after the tenancy ends, possession is delivered, and the tenant makes a written demand for the money.

Cited to 41 O.S. § 115 (A)-(G) and 1 more cited source · Verified October 2, 2026

That written demand is not optional fine print: a tenant who fails to demand the deposit in writing within six months of the tenancy ending forfeits it — the statute says the deposit 'reverts to the landlord' outright. Any deductions for unpaid rent or damages must be itemized in a written statement delivered by return-receipt mail or in person. A landlord who fails to comply owes the tenant the deposit and any prepaid rent back — Oklahoma has no double- or triple-damages multiplier — but the prevailing party in the lawsuit collects attorney fees, and misappropriating escrowed deposit money is a crime punishable by up to six months in county jail and a fine of up to twice the amount taken.

Oklahoma security deposits at a glance

Maximum deposit	No statutory cap
Return deadline	45 days
Deadline conditions	The clock does not start at move-out. It runs from the latest of three events — the tenancy terminating, possession being delivered, and a WRITTEN demand from the tenant — and the balance comes back without interest. 41 O.S. 115(B) says 'within forty-five (45) days after the termination of tenancy, delivery of possession and written demand by the tenant.' The demand must be written (stricter than AZ/SC, where any demand suffices), and it carries a deadline of its own: 'If the tenant does not make such written demand of such deposit within six (6) months after termination of the tenancy, the deposit reverts to the landlord in consideration of the costs and burden of maintaining the escrow account, and the interest of the tenant in that deposit terminates at that time.' Return is 'without interest.'
Itemization required	Yes
Itemization rules	Deductions are limited to accrued rent and damages suffered by reason of the tenant's noncompliance with the act and the rental agreement, 'all as itemized by the landlord in a written statement' (41 O.S. 115(B)). The statute prescribes the delivery method for the itemized statement: by mail, return receipt requested, to be signed for by any person of statutory service age at the address, or in person to the tenant 'if he can reasonably be found.'
Separate account required	Yes
Interest owed to tenant	No
Account & interest rules	No interest is ever owed to the tenant. Section 115(B) expressly says the balance is returned 'without interest,' and the 6-month reversion clause frames the escrow cost as the landlord's consideration. The escrow account itself IS mandatory, but it generates nothing for the tenant.
Pet deposits	No statute addresses a pet deposit, and no general deposit cap exists for one to count against. The pet-deposit rule, pet rent and fees, and the assistance-animal rules are on the pets and assistance animals page.
Non-refundable fees allowed	Not addressed by statute
Penalty for violation	The civil remedy is a bare recovery of the deposit and any prepaid rent, with no statutory multiplier. Misappropriating escrowed deposit money is separately a crime, punishable by up to six months in county jail and a fine of up to twice the amount taken. Those are two distinct tracks that secondary sources routinely conflate. Civil: if the landlord fails to comply with the section or to return prepaid rent, 'the tenant may recover the damage and security deposit and prepaid rent, if any' (115(E)) — a bare recovery remedy with NO statutory multiplier, though the prevailing party gets reasonable attorney fees under 41 O.S. 105(B). Criminal: 'Misappropriation of the security deposit shall be unlawful and punishable by a term in a county jail not to exceed six (6) months and by a fine in an amount not to exceed twice the amount misappropriated from the escrow account' (115(A)) — the 'twice the amount' figure is a criminal fine cap payable to the state, not tenant damages.
Tenant forwarding-address duty	No statutory duty to furnish a forwarding address — instead Oklahoma imposes a harsher affirmative duty: make WRITTEN demand for the deposit within six months of termination or the deposit reverts to the landlord permanently (115(B)).

Notes and caveats

No cap on deposit size — none of any kind — Section 115 contains no cap on what a landlord may collect. The blank here means no statutory limit exists, not a limit of zero.
Stale-source trap: the "two months' rent" cap — Property-management sites circulate a claim that Oklahoma caps deposits at two months' rent. No such cap exists anywhere in § 115.
The escrow account is mandatory, not a best practice — Section 115(A) says the deposit "must be kept in an escrow account for the tenant ... maintained in the State of Oklahoma with a federally insured financial institution." Some guides soften this into a recommendation, but the statute says "must" and backs it with a criminal misappropriation offense.
Stale-source trap: "45 days after move-out" — The 45-day clock does not start at move-out — it needs all three triggers, including a WRITTEN demand from the tenant. And a tenant who makes no written demand within six months loses the deposit outright to the landlord, a reversion rule most 50-state charts omit.
Stale-source trap: "the tenant recovers double the deposit" — The 2x figure belongs to § 115(A) and is the cap on a criminal FINE payable to the state, not a civil award to the tenant. The civil remedy in § 115(E) carries no multiplier at all.
The deposit is not last month's rent — Section 115(F) bars a tenant from applying the deposit to the last month's rent unless the rental agreement allows it.
The deposit follows the property — Sections 115(C)–(D) apply when the landlord's interest in the unit ends by sale, assignment, death, bankruptcy, the appointment of a receiver or otherwise. Within a reasonable time the person holding the deposits must either transfer them to the successor in interest and notify the tenants in writing of the transfer and of the transferee's name and address, or return the deposits to the tenants. A successor who receives them takes on all of a landlord's rights and obligations for those deposits.
Nonrefundable fees: the act says nothing either way — The ORLTA neither authorizes nor prohibits nonrefundable fees, and § 102(11) excludes deposits from the definition of "rent" — making this a lease-drafting question rather than a statutory one. That silence, not a prohibition, is why the answer is blank here.

How this record was verified: Direct read of statute text in the Oklahoma Legislature's complete-title files (oklegislature.gov/OK_Statutes/CompleteTitles: Titles 41, 12, 11, 15 and 25, each generated December 30, 2025), read again on October 2, 2026: 41 O.S. 61, 102 to 105, 109, 111, 115, 121, 123, 124, 128, 131 and 132; 12 O.S. 1148.1 to 1148.16, 990A, 1751 and 2006; 11 O.S. 14-101.1; 15 O.S. 213 to 215; 25 O.S. 82.1; and Article V of the Oklahoma Constitution. Every key figure was read word for word: the escrow-account requirement, the misappropriation penalty (county jail up to 6 months plus a fine up to twice the amount misappropriated), the 45-day return clause with its three triggers (termination of tenancy, delivery of possession and written demand by the tenant), the 6-month demand window with reversion to the landlord, 'without interest', the 30-day and 7-day termination notices of 111(A)-(B), the 'one (1) day's notice ... reasonable times' entry rule of 128(C), and the 5-day rent demand of 131(B). Negative checks run against the full text of Title 41 (the residential act and the older sections): no deposit cap, no deposit interest, and no late-fee amount, structure or grace period anywhere in the title. No act of the 2025 or 2026 sessions amended a section these answers rest on: the Legislature's bill pages and its measures-by-citation report show Senate Bill 128 of 2025 vetoed on May 5, 2025, and Senate Bill 1296, House Bill 3389, Senate Bill 1209, House Bill 2015 and House Bill 3386 of 2026 not enacted when the session adjourned on May 29, 2026. The municipal codes of Oklahoma City, Tulsa, Norman and Broken Arrow were read for rent regulation. The Supreme Court of Oklahoma's order 2020 OK 22 was read on the Oklahoma State Courts Network on October 2, 2026.
