Deposits are not income when received
Under IRS Publication 527, a security deposit is not includable in your gross income when you receive it, as long as you are legally obligated to return it to the tenant at the end of the lease. Holding someone else's money in a segregated account is not a taxable event.
This is true even if the deposit sits in your bank account commingled with other funds — what matters for tax purposes is your legal obligation to return it, not how you hold it. (State landlord-tenant laws may impose separate requirements on how security deposits are held.)
When a deposit becomes taxable
A security deposit becomes taxable income in the year you apply it to rent or retain it for damages. If a tenant moves out and you keep $500 for unpaid last month's rent and $200 for repairs, you report $700 as rental income in that year.
If you apply the deposit to a specific expense — like a repair you deduct — the income and the deduction roughly offset each other. But you still must report the deposit as income even if you immediately spend it fixing damage.
Last month's rent paid upfront
If a tenant pays first and last month's rent at move-in, the last month's rent is taxable income in the year received, because there is no obligation to return it. Unlike a security deposit, this payment covers rent you've already agreed to accept and cannot be refunded. Report it as rental income in the year of receipt.
The cash vs. accrual method sets the timing
Most individual landlords use the cash method, so income is reported when actually or constructively received and expenses when paid. Under cash accounting, a refundable deposit is not income at receipt (you owe it back), and it becomes income the moment you apply or keep it. An accrual-method landlord follows the same principle for a true deposit — the obligation to return it keeps it off the income statement until forfeited — but must otherwise report rent when earned rather than when collected.
The distinction rarely changes the ultimate tax, but it changes the year. If you retain a deposit in December for damage but do not pay for the repair until January, a cash-basis landlord reports the retained deposit as income in the first year and deducts the repair in the second. Straddling a year-end this way can shift a small amount of income between returns, so note the dates on move-outs that happen near December 31.
A worked example: partial retention at move-out
A tenant paid a $2,000 refundable security deposit at move-in — not reported as income then. At move-out you find $650 of tenant-caused damage (a broken interior door and carpet cleaning beyond normal wear) and $400 of unpaid last month's rent. You keep $1,050 and refund $950. In the year of move-out you report $1,050 as rental income: the $400 rent portion and the $650 damage portion.
You then deduct the amounts you actually spend fixing the tenant-caused damage. If the $650 covers a deductible repair (patching, carpet cleaning, repainting a damaged wall), the deduction roughly offsets the income, making that slice close to a wash. But if part of the retained deposit funds a capital improvement — say you replace the entire carpet or upgrade the door — that cost is capitalized and depreciated over years rather than deducted at once, so the income and the write-off no longer match up in the same year. Classify each repair before assuming it nets to zero.
Nonrefundable fees are income when received
Not everything collected at move-in is a deposit. A nonrefundable fee — a nonrefundable pet fee, a move-in fee, or a nonrefundable cleaning fee — is taxable rental income in the year you receive it, because you have no obligation to return it. The label on the lease matters: a "pet deposit" that is refundable if there is no pet damage is a deposit (not income until retained), while a "pet fee" you keep regardless is income immediately.
This trips up landlords who lump all move-in money together. Separate the truly refundable deposit (held, not income) from any nonrefundable fees (income now) on your books, and word the lease so the two categories are unambiguous. Getting the characterization wrong either overstates income in the move-in year or understates it, and both are easy for an examiner to spot against the lease.
Interest earned on the deposit
Many states and cities require landlords to hold security deposits in a separate account and to pay the tenant interest, sometimes annually. The federal tax treatment follows who ultimately keeps the interest. If the interest belongs to and is paid to the tenant, you generally report the interest as income and then deduct the amount paid over to the tenant, so it nets out. If you are allowed to keep the interest (some jurisdictions permit an administrative share), the portion you keep is your taxable income.
Either way, the bank will issue a Form 1099-INT for interest earned in an account under your taxpayer ID, so account for it rather than ignoring it. The mechanics are small dollars, but mismatches between a 1099-INT and your return are a common source of automated IRS notices.
Applying the deposit to the final month's rent
Sometimes a departing tenant asks you to "use the deposit for last month's rent." The moment you agree and apply it, that amount stops being a refundable deposit and becomes rental income in the year applied. There is nothing wrong with allowing it, but recognize the tax consequence: you have converted a non-taxable held deposit into taxable rent for that year. Landlords who want to avoid a surprise sometimes decline the request and collect the final month's rent normally, refunding the deposit after inspection — but the tax result of collecting that rent is the same either way.
Recordkeeping and staying out of trouble
Because a deposit shifts between non-income and income depending on what you do with it, clean records are the whole game. Keep the lease showing the deposit amount and refundability, a dated move-out inspection with photos, an itemized statement of what you retained and why, receipts for every repair funded by retained deposit money, and the refund check or record. Reconcile the deposit ledger each year so the amount you report as retained matches your itemization.
This documentation does double duty: it supports your tax reporting and it is exactly what most state landlord-tenant laws require you to provide the tenant within a set number of days after move-out. Federal tax rules and state deposit-handling rules are separate regimes — following one does not satisfy the other — but a single well-kept file covers both.
When damage exceeds the deposit
If a tenant causes more damage than the deposit covers, the tax picture splits in two. The retained deposit is income when you keep it, and the repair costs are deductible (if repairs) or capitalized (if improvements) as usual — the same rules as any move-out. Any additional amount you actually collect from the tenant beyond the deposit — whether they pay you directly or you win a small-claims judgment — is likewise rental income when received.
What you generally cannot do is deduct the value of your own unpaid time or claim a loss for damage you were never compensated for beyond your actual costs. Your deduction is tied to what you spend fixing the property, not to the amount you were "owed." If a judgment goes uncollected, there is no separate bad-debt deduction for a cash-basis landlord, because the unpaid amount was never reported as income in the first place.
Deposits held by a property manager
If a management company collects and holds security deposits on your behalf, the deposits are still yours for tax purposes, and the same timing rules apply: not income until applied or retained. The manager's year-end statement (and the Form 1099 they may issue you) should separate refundable deposits held in trust from rent and retained amounts. Reconcile their report against your own records — errors here, such as a manager booking a held deposit as current rent, are a common cause of overstated income.
Be especially careful in the handoff year when you buy or sell a property: security deposits are typically transferred to the new owner at closing (often as a credit on the settlement statement). That transfer is not rental income to either party — it is simply moving the tenants' money to whoever now owes it back — but it must be tracked so the deposit obligation follows the property to the correct taxpayer.
Frequently asked questions
Do I report a security deposit as income on my taxes?
Not when you receive it. Report it as income only in the year you keep part or all of it (applying it to unpaid rent or damages).
What if I never return the deposit?
If you keep the deposit at lease end — for any reason — it becomes taxable income in that tax year.
Are last month's rent and a security deposit treated the same way?
No. Last month's rent is taxable when received. A refundable security deposit is not taxable until you retain it.
Is a nonrefundable pet fee or cleaning fee taxable when I collect it?
Yes. A truly nonrefundable fee is rental income in the year received because you have no obligation to return it. Only a refundable deposit is deferred until you retain it.
If I keep a deposit to cover repairs, is it a wash?
For deductible repairs, roughly yes — the income from the retained deposit is offset by the repair deduction. But if you use the money for a capital improvement, that cost is depreciated over years instead of deducted at once, so it does not net out in the same year.
Do I have to report interest earned on a tenant's security deposit?
Generally yes. The bank reports the interest under your taxpayer ID on a 1099-INT. If the interest is paid over to the tenant, you report it and deduct the amount passed through; any portion you are allowed to keep is your taxable income.
Does applying the deposit to the last month's rent make it taxable?
Yes. Once you apply a refundable deposit to rent, that amount becomes taxable rental income in the year applied, just like any other rent received.
