You hand your landlord $2,000 as a security deposit. They hold it for three years. In that time, the money could have earned interest in a savings account. So here is a fair question: does your landlord owe you interest on your deposit when you move out?
The answer depends entirely on where you live. About a third of states require landlords to pay interest on security deposits, while the rest require nothing at all. Even where interest is required, the rules about rates, timing, and escrow accounts vary widely. This guide maps the landscape so you know what to expect and what to ask for.
The Short Answer
In most of the United States, landlords do not have to pay interest on security deposits. There is no federal law on the subject, and roughly two-thirds of states are silent on it, which means the landlord keeps any interest the deposit earns, or earns none at all if the money sits in a non-interest-bearing account.
Where laws do exist, they typically require the landlord to hold the deposit in a separate interest-bearing account and to pay the tenant the accrued interest annually or at move-out. The interest rates are usually modest, tied to market rates or set by statute at a low fixed percentage. Nobody is getting rich from deposit interest, but over a multi-year tenancy it can amount to a meaningful sum. If you want the full picture of how security deposits work, start there, then come back for the interest rules.
How Interest Requirements Typically Work
States that mandate interest generally use one of three models. The first requires the landlord to pay interest at a specific rate set by law, regardless of what the account actually earns. These statutory rates are often low, sometimes 1 to 2 percent, but they are predictable.
The second model requires the landlord to pay whatever interest the account actually earns. Under this approach, the landlord must place the deposit in an interest-bearing account, and the tenant receives the real earnings. When rates are near zero, the tenant receives near zero, which is fair but unexciting.
The third model ties the rate to a market benchmark, such as the average savings account rate published by a banking regulator. This keeps the rate realistic without requiring the landlord to track a specific account’s performance. Some states also let the landlord deduct a small administrative fee from the interest before paying it to the tenant.
Separate Accounts and Escrow Rules
Interest requirements almost always come paired with rules about where the deposit is held. The most common rule is that deposits must go into a separate bank account, not mixed with the landlord’s operating funds. Commingling deposit money with personal or business funds is illegal in many states, whether or not interest is required.
Several states go further and require the account to be in the tenant’s name, or require the landlord to notify the tenant of the bank and account number where the deposit is held. These rules exist to protect tenants if the landlord goes bankrupt or disappears: money in a properly segregated account is much easier to recover. If your landlord cannot tell you where your deposit is held, that is worth a follow-up question in writing.
When and How Interest Gets Paid
Timing rules vary. Some states require landlords to pay accrued interest to the tenant every year, often on the anniversary of the lease or at the end of each calendar year. Others let the interest accumulate and pay it as a lump sum when the tenant moves out, added to the deposit refund.
Annual payment rules are more tenant-friendly in practice, because tenants who move out mid-cycle sometimes have trouble collecting small accrued amounts. If your state requires annual payment and your landlord has never sent you an interest check, ask for an accounting. Landlords who are unaware of the rule usually comply once it is pointed out, since the amounts are small and the penalties for non-compliance can be larger than the interest itself.
What Counts Toward the Interest Calculation
Interest is calculated on the deposit amount actually held, starting from when the landlord receives it. If you paid a $1,500 deposit, interest accrues on $1,500. Last month’s rent collected upfront is generally not treated as a security deposit for interest purposes, even in states that regulate it, unless the lease or state law says otherwise.
Deductions complicate the picture slightly. If the landlord withholds $400 for legitimate deductions, interest is typically owed on the full amount for the period it was held, not just on the refunded portion. The deduction reduces what comes back to you, but it does not retroactively reduce the interest earned while the full amount sat in the account.
States With No Interest Requirement
In states without an interest law, landlords may still choose to hold deposits in interest-bearing accounts, but they are not obligated to share the earnings. Most small landlords in these states use ordinary accounts and the question never arises. Large management companies sometimes earn interest on pooled deposits as a matter of treasury management, and in unregulated states they keep it.
Tenants in these states occasionally try to negotiate interest into the lease, but landlords rarely agree, since it creates bookkeeping work for little benefit to them. A more productive negotiation is over the deposit amount itself: in states with no interest requirement, reducing a two-month deposit to one month saves you far more than interest ever would.
Penalties for Non-Compliance
States that require interest usually attach penalties for landlords who ignore the rule. Common penalties include forfeiting the right to withhold any of the deposit, paying the tenant a multiple of the deposit as damages, or owing the tenant’s attorney fees in a dispute. These penalties are deliberately set higher than the interest amounts to give the rule teeth.
In practice, most violations are oversights rather than malice. Small landlords often do not know their state’s interest rules, especially in states where the requirement was added by a recent amendment. A polite written inquiry citing the statute usually resolves it. Reserve formal complaints for landlords who ignore clear written requests.
How to Find Out What Applies to You
Start with your state’s security deposit statute, which is usually easy to find with a search for your state name plus “security deposit interest law.” Look for the current version, because rates and rules are amended periodically. Your state’s attorney general or housing agency often publishes a plain-language tenant guide that covers deposit interest alongside other rules.
Next, check your lease. Some landlords in unregulated states voluntarily include interest provisions, and some landlords in regulated states restate the statutory rule in the lease for clarity. If the lease promises interest, that promise is enforceable even where the law does not require it. Finally, ask your landlord directly and in writing where the deposit is held and whether interest will be paid. The answer, or the lack of one, tells you a lot. Tenants comparing protections across states may also want to review rent increase laws by state, since states with strong deposit rules often have strong rent rules too, and tenant rights under the lease more broadly.
Frequently Asked Questions
How much interest will I actually earn?
Usually very little. At a 1 percent statutory rate on a $1,500 deposit, one year earns $15. The value of these laws is less in the dollars and more in the account-segregation rules that come with them, which protect your deposit from being spent or lost.
Does interest apply to pet deposits?
In states with interest requirements, pet deposits that function as security deposits are generally covered. Non-refundable pet fees, which are not deposits at all, are not covered. The distinction depends on whether the money is refundable.
Can my landlord deduct expenses from the interest?
Some states allow landlords to deduct a small administrative fee from the interest before paying it to the tenant. What landlords cannot do is treat the interest as part of the deposit and withhold it for damages. Interest belongs to the tenant, subject only to the specific deductions the statute allows.
What if I move out before a full year?
Interest is typically prorated for partial years. If your state requires annual payment and you move out after seven months, you are owed seven months of interest, usually paid with your deposit refund. Ask for an itemized accounting that shows the interest calculation separately.
