Your landlord is holding your money. In some states, they're required to earn interest on it and pay it to you. In most states, they're not required to do anything with it except return it at the end of your tenancy. Knowing whether your state requires deposit interest determines whether you should ask about it.
Which States Require Security Deposit Interest
A minority of US states require landlords to hold residential security deposits in interest-bearing accounts and pay interest to tenants. The states with explicit interest requirements include: New York (pays interest on deposits held more than one year), New Jersey (pays interest annually, currently tied to market rates), Massachusetts (pays 5% simple interest or actual rate earned, whichever is higher), Illinois (pays interest on deposits held more than 6 months in municipalities with over 25,000 residents), Iowa (pays market interest on deposits in accounts of $100 or more), and several others. Most other states have no interest requirement. Check your specific state and municipality — some cities have interest requirements even in states with no statewide rule.
How Interest Is Calculated and When It's Paid
In states with deposit interest requirements, the calculation and payment timing vary. New York requires annual statements and payment of interest annually or credit against rent. New Jersey computes interest based on the rate paid by money market accounts and requires payment each year at lease anniversary. Massachusetts allows landlords to hold deposits in separate trust accounts and pay interest at a 5% rate (or actual rate if higher). The amounts aren't huge on a 1-year lease — $1,500 deposit at 5% is $75 — but on multi-year tenancies with larger deposits, the interest can be meaningful. More importantly, in states with interest requirements, failure to pay interest can result in forfeiture of the right to retain the deposit.
Commercial Deposits Almost Never Earn Interest for Tenants
State security deposit interest requirements apply almost exclusively to residential leases. Commercial tenants generally have no statutory right to deposit interest regardless of state law. However, commercial tenants can negotiate deposit interest provisions directly into their lease. For large commercial deposits — a 6-month deposit on a $15,000/month lease is $90,000 — the interest is significant. At 4%, $90,000 in deposit generates $3,600/year. Over a 5-year lease, that's $18,000 in interest that's the landlord's income unless the lease specifies otherwise. Push for: deposit held in a separate interest-bearing account; interest credited to tenant annually; and interest paid to tenant at lease end along with deposit return.
Separate Account Requirements Protect Your Deposit
Beyond interest, some states require landlords to hold security deposits in separate accounts, not commingled with their own funds. New York, New Jersey, and Massachusetts have these requirements for residential landlords. The purpose: if the landlord goes bankrupt or faces financial difficulty, commingled deposits disappear into the bankruptcy estate. Deposits held in separate accounts are protected from the landlord's creditors and must be returned to tenants even in the landlord's bankruptcy. For commercial tenants, negotiate a separate account requirement into the lease regardless of state law — a landlord who commingles a large commercial deposit with operating funds provides significantly less security that you'll see your deposit returned.
What to Do If Your Landlord Isn't Paying Required Interest
If you're in a state with deposit interest requirements and your landlord has never paid or credited deposit interest, you may have a claim. First, confirm the requirement applies to your tenancy (check your state statute and any local ordinance). Second, calculate the interest owed — from the start of your tenancy to the present at the required rate. Third, send a written demand to your landlord for the unpaid interest, referencing the specific statute. In states where unpaid deposit interest triggers deposit forfeiture (like New York under certain circumstances), the demand carries significant leverage. If the landlord doesn't pay, small claims court is an appropriate venue for claims of $1,000–$5,000 in interest.
Key Takeaways
- New York, New Jersey, Massachusetts, Illinois, and Iowa among others require deposit interest for residential tenants
- Interest requirements are almost exclusively residential — commercial tenants must negotiate interest provisions directly
- Separate account requirements protect deposits from landlord bankruptcy — negotiate these into commercial leases
- Calculate and claim unpaid required interest through written demand and small claims court if necessary
- Large commercial deposits of $50,000+ generate meaningful annual interest — include interest provisions in every commercial lease
Frequently Asked Questions
- How much interest can I earn on my security deposit?
- At statutory rates of 3-5%, a $3,000 deposit over a 3-year tenancy earns $270-$450 in interest. At current higher rates available in money market accounts, interest can be substantially higher. In Massachusetts, where deposits earn the savings account rate, a deposit in a high-yield account could earn significantly more.
- What if my landlord put my deposit in a non-interest-bearing account?
- If your state requires an interest-bearing account, the landlord has violated that requirement. You can demand the interest that should have been earned and may be entitled to additional penalties. Document the request in writing.
- Can I apply deposit interest to my rent?
- In some states, tenants have the right to apply accumulated deposit interest toward rent. Massachusetts explicitly allows this. In most states, the interest is paid at move-out with the deposit return.
- Is the interest paid on a security deposit taxable income?
- Yes. Security deposit interest is taxable income. Landlords should provide a 1099 for interest paid if required by IRS rules. Keep records of interest received.
- What is a 'last month's rent' and does it earn interest?
- Last month's rent is a pre-payment of the final month's rent, not a security deposit. In Massachusetts, last month's rent must also be held in an interest-bearing account. In most other states, it's held by the landlord without interest requirements because it's a pre-payment, not a deposit.
