A security deposit is not taxable income for landlords in the year you receive it, because you have a legal obligation to return the money if the tenant meets the lease terms. It converts to taxable rental income only when something gives you an unconditional right to keep some or all of it: damage beyond normal wear, unpaid rent, an early lease break, or a written agreement that turns the deposit into rent.1Internal Revenue Service. Publication 527 (2025), Residential Rental Property When that happens, you report the retained amount on Schedule E for the year the right crystallizes.
Why the Deposit Sits Outside Your Income
What the lease calls the payment doesn’t decide the tax treatment. The question is whether you are actually obligated to give the money back. If the tenant can recover the funds by fulfilling the lease, the deposit is a liability on your books, not income, and it stays off your return until a triggering event occurs.2Internal Revenue Service.

This holds for cash-basis landlords, which covers most individual owners. The money legally belongs to the tenant while the lease runs. Many states require landlords to keep the deposit in a separate escrow or trust account, which reinforces the point: the funds aren’t yours to spend, and they aren’t yours to tax yet either.
When a Security Deposit Becomes Taxable
The IRS looks at the moment your right to keep the funds becomes unconditional. Not when the lease was signed. Not when the tenant handed over the check. The specific triggers matter.
The Tenant Breaks the Lease
If you keep part or all of the deposit because the tenant vacates early or otherwise violates the lease, the retained amount is income in the year you keep it.3Internal Revenue Service. Topic No. 414 Rental Income and Expenses A tenant who walks out in March of a 12-month lease triggers income that year, not in December when the lease would have ended.
Applied to Repairs or Damages
When you withhold money to cover damage beyond normal wear and tear, the retained portion becomes income in the year you complete the final accounting with the tenant.1Internal Revenue Service. Publication 527 (2025), Residential Rental Property You then deduct the actual repair costs as a rental expense, so the net tax impact is often near zero.
There is a wrinkle. If you normally deduct repair costs as expenses, include the retained deposit in income and deduct the repairs. If your practice is not to deduct repair costs, you don’t include the reimbursed amount in income at all.3Internal Revenue Service. Topic No. 414 Rental Income and Expenses Most landlords deduct repairs, so most report the retained deposit as income and take the offsetting deduction.
Applied to Unpaid Rent
When you apply the deposit to cover a rent shortfall, the applied amount is rental income at that point. It doesn’t matter whether the application happens mid-lease after a missed payment or at the end as a final settlement. The funds have shifted from security into rent, and rent is always taxable.4Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined
Mid-Lease Conversion to Non-Refundable
Sometimes a landlord and tenant agree partway through the lease to convert a refundable deposit into prepaid rent or a non-refundable payment. The deposit becomes taxable on the date of that agreement, regardless of which months the money is meant to cover. Once your obligation to return the funds disappears, the IRS treats the money as earned.
Payments That Look Like Deposits But Aren’t
Two categories often collected alongside a security deposit are taxable the moment they hit your account, so keep them separate on your books.
Non-Refundable Fees
Any upfront payment the tenant cannot get back is rental income in the year you receive it, whatever the lease calls it. Non-refundable pet fees, cleaning fees, and move-in fees all qualify. With no obligation to return the money, these are taxable from day one under the broad definition of gross income.4Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined
Last Month’s Rent
A common move-in arrangement is first and last month’s rent plus a deposit. The portion earmarked for the final month is not a security deposit. It is advance rent, and the IRS requires you to include advance rent in income in the year you receive it, no matter when the rental period actually occurs.1Internal Revenue Service. Publication 527 (2025), Residential Rental Property A tenant who moves in during December 2026 and pays last month’s rent for a lease ending November 2027 generates 2026 income. The rule applies whether you use cash or accrual accounting.2Internal Revenue Service. Rental Income and Expenses – Real Estate Tax Tips
If you collect both at signing, the security deposit stays off your return; the last month’s rent goes on it. Mixing them up is one of the more common errors flagged on rental audits.
Interest on the Deposit Account
Several states and municipalities require landlords to hold deposits in interest-bearing accounts and pay the accumulated interest to the tenant. Who reports the interest depends on who keeps it. If you must pass it along to the tenant, it is the tenant’s income. If your lease or local law lets you retain the interest, you report it as taxable interest income in the year it accrues. Either way, the deposit principal itself remains a non-taxable liability until a triggering event.
How to Report a Retained Deposit
Once the deposit becomes taxable, report the amount as rental income on Schedule E (Form 1040), the same form where you report monthly rent. Repair costs the deposit covered go on the expense lines of the same Schedule E, reducing your net rental income.3Internal Revenue Service. Topic No. 414 Rental Income and Expenses
Both the income and the deduction belong in the tax year the deposit was forfeited and the repairs were completed. If a tenant moves out in December and you finish repairs in January, you may need to split the recognition across two tax years depending on when the final accounting occurs and when you pay for the work.
Records to Keep
The IRS expects landlords to document rental income and expenses, and audit exposure grows quickly when you can’t produce support for what you reported. For deposits specifically, hold onto the lease, the move-in and move-out inspection reports, repair receipts and invoices, the itemized deposit accounting letter you send the tenant, and bank statements for the escrow account. The IRS generally requires documentary evidence such as receipts, canceled checks, or bills to support expense deductions.5Internal Revenue Service. Tips on Rental Real Estate Income, Deductions and Recordkeeping
Keep these records for at least three years after filing the return that includes the deposit income. That matches the standard audit window for most individual returns.
