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

Verified August 28, 2026 All New Mexico topics →

New Mexico requires a landlord to pay annual interest on a security deposit, but only under an annual rental agreement where the deposit is greater than one month's rent — and the rate the statute names stopped existing in 1986.

Cited to NMSA 1978 § 47-8-18 (Deposits) — official annotated text of chapter 47 (A)(1), (A)(2), (B), (C), (D), (E) and 3 more cited sources · Verified August 28, 2026

Section 47-8-18(A)(1) sets the figure at "the passbook interest permitted to savings and loan associations in this state by the federal home loan bank board." That is a reference to a legal ceiling rather than to a market rate, and the federal authority to set such ceilings expired on March 31, 1986; the Federal Home Loan Bank Board was abolished three years after that. The words have stood unchanged since the section was last amended in 1989, and no New Mexico court, Attorney General opinion, agency rule or court form has ever supplied a substitute. So the duty sits on the books while the amount cannot be worked out from the statute, and no figure is published here. When interest is owed it runs on the entire deposit, not on the part above one month's rent, and it is payable every year. Nothing in the deposit section penalizes a landlord who never pays it; the tenant's real lever is the Act's two-way prevailing-party attorney-fee rule.

Rate rules

The statute names a rate source that no longer exists. Section 47-8-18(A)(1) requires "an interest equal to the passbook interest permitted to savings and loan associations in this state by the federal home loan bank board." That points not at a market rate but at a legal ceiling — the most a savings and loan was permitted to pay. Congress ordered those ceilings phased out, and the federal authority to set them expired on March 31, 1986; since April 1, 1986 no passbook rate has been permitted to anyone. The Federal Home Loan Bank Board itself was abolished in 1989. New Mexico last amended § 47-8-18 on June 16, 1989, and the words have stood unchanged ever since.

No New Mexico authority has filled the gap. The one appellate opinion that quotes the clause stops with an ellipsis exactly where the dead words begin and decides the case on other grounds (Hedicke v. Gunville, 2003-NMCA-032). The Attorney General has never opined on the section. The Administrative Code sets no substitute rate, no uniform jury instruction reaches it, and the Supreme Court's own complaint form for the return of a deposit has no line for interest at all. Four bills reopened the section between 1999 and 2023 and carried the clause forward word for word, and the 2025 rewrite of the Act did not mention it.

So the duty is real and the amount is not ascertainable from the statute. No lawful figure can be computed, and none is published here.

Accrual and payment Interest is payable annually: the owner "shall be required to pay to the resident annually an interest ... on such deposit." The statute fixes no measuring date, so it does not say whether the year runs from the lease anniversary or on the calendar, and it requires no notice, statement or accounting of the interest. When interest is owed it runs on the whole deposit, not on the portion above one month's rent.
Who and what is covered Two conditions, both in § 47-8-18(A)(1), and both must hold: the tenancy is under an annual rental agreement, and the owner demanded or received a deposit greater than one month's rent. The two fit together, because under an agreement shorter than a year the owner may not demand or receive a deposit above one month's rent at all (§ 47-8-18(A)(2)) — so a deposit large enough to carry interest can lawfully exist only on a lease of a year or more. "Annual rental agreement" is not defined in the Act; New Mexico Legal Aid's renter's guide reads it as a written lease for a term of a year or more. The money must also be a genuine damage deposit within the Act: the Court of Appeals held that a sum nearly thirty-two times the monthly rent was not a security deposit and so bore no interest (Hedicke v. Gunville, 2003-NMCA-032).
Statute controls where or how the deposit is held No statute addresses how the deposit is held
Interest-bearing account required No statute addresses whether the account must bear interest
Custody rules No statute addresses custody of the deposit
Penalty for violation

Nothing in the deposit section penalizes a failure to pay the interest. The forfeitures in § 47-8-18(D) — the owner loses the right to withhold any part of the deposit, loses any counterclaim, becomes liable for court costs and reasonable attorney fees, and loses an independent action for damage to the property — are triggered only by the failure to deliver the itemized written statement of deductions within thirty days of termination, as the Court of Appeals held in Stodgell v. Weissman, 2025-NMCA-003. The $250 civil penalty in § 47-8-18(E) is tied to retaining a deposit in bad faith, not to unpaid interest.

What does reach interest is § 47-8-48(A): in a suit to enforce any provision of the Uniform Owner-Resident Relations Act, the prevailing party is entitled to reasonable attorney fees and court costs. It runs both ways, so a tenant who sues for the interest and loses can be ordered to pay the owner's fees. Unpaid interest can also be raised as a counterclaim in an action for possession or rent (§ 47-8-30(A)).

Local rules Neither Albuquerque nor Santa Fe adds a deposit-interest rule of its own, so § 47-8-18 governs unmodified in both cities.
