Does a landlord have to pay interest on a security deposit in Montana?

Verified August 28, 2026 All Montana topics →

Montana requires no interest on a residential security deposit, and its deposit chapter does not mention interest, accounts, or banks at all.

Cited to Mont. Code Ann. § 70-25-201 (security deposit; deductions authorized) and 2 more cited sources · Verified August 28, 2026

Title 70, chapter 25 is nine sections long and covers five things: what counts as a security deposit, what may be deducted from it, a written list of any rent due and damage and cleaning charges delivered with the balance within 30 days of the tenancy ending or the premises being surrendered and accepted, whichever comes first — within 10 days where there is no damage, no cleaning required, and no rent or utilities unpaid — the loss of all deduction rights if the landlord never provides that list, and liability for anything wrongfully withheld. Not one of the nine sections says where the money is held, whether it earns anything, or who gets what it earns. The chapter reaches as widely as it can: § 70-25-102 applies it to all rentals of dwellings under the Residential Landlord and Tenant Act and under the mobile home park chapter alike, so park spaces get the same answer as apartments. And § 70-25-103 makes any lease provision contrary to the chapter invalid and any tenant waiver invalid — which cuts nothing here, because there is no interest duty for a lease to waive.

How this record was verified: Direct read of the whole of the Montana Code Annotated 2025, title 70, chapter 25 (Residential Tenants' Security Deposits), on the Legislative Services Division's code site — all nine sections, 70-25-101 through 70-25-206, read in full and searched for interest, account, trust, escrow, bank, accrual and investment terms, none of which occurs anywhere in the chapter, including its headings and history lines. Title 70, chapter 24 (the Residential Landlord and Tenant Act of 1977) was checked heading by heading across all four of its parts for any deposit-holding provision, and its one security-deposit section, 70-24-112, read in full. Currency taken from the chapter's own history lines, which carry the 2025 session amendments to 70-25-201 and 70-25-202.
