Why security deposits are not income when received
When a tenant pays a security deposit, you hold it as a refundable liability. The key word is refundable — if the tenant pays all rent, leaves the unit undamaged, and complies with the lease, you owe it back. Because you do not have an unrestricted right to use or keep the funds, the IRS does not treat the deposit as gross income at the time of receipt.
This principle is embedded in the cash-method rules that most landlords use. Under cash-method accounting, you recognize income when you receive funds that you are entitled to keep. A refundable deposit does not meet that test. It sits on your balance sheet as a liability — money you hold but do not own — until a triggering event (nonpayment, damage, or lease violation) allows you to retain it.
The practical implication: a landlord who collects $3,000 in rent and $3,000 in security deposit in January reports $3,000 of rental income for January, not $6,000. The deposit is accounted for separately and held until the lease ends.
When deposit interest is your income vs. the tenant's
The tax treatment of interest earned on a security deposit depends on who is legally entitled to that interest — which is a question of state landlord-tenant law, not federal tax law.
States where landlords keep the interest: Some states have no requirement that landlords segregate or account for interest earned on security deposits. In those states, any interest the deposit earns belongs to the landlord and is ordinary income reportable on the landlord's federal return.
States that require landlords to pay interest to tenants: A number of states require landlords to hold security deposits in separate interest-bearing accounts and to remit the accrued interest to the tenant — either annually or at lease end. In these states, the landlord acts as a conduit. The interest income belongs to the tenant from the moment it accrues, so the tenant reports it on their federal return (typically as interest income on Schedule B). The landlord neither includes it in gross income nor takes a deduction for the remittance.
States with hybrid rules: Some states require segregated accounts but allow the landlord to keep a portion of the interest (sometimes as an administrative fee) and remit the rest to the tenant. In that case, the landlord reports only the portion they are entitled to keep.
Because state rules vary significantly, you should verify your state's specific landlord-tenant statute before deciding how to report deposit interest. What is true in one state may be entirely different across the border.
What Form 1099-INT means for landlords
If you hold a security deposit in a savings account or money market account that earns interest, the bank will issue a Form 1099-INT to you if the interest exceeds $10 in the year. That 1099-INT will show your name and Social Security number (or EIN) as the account holder, and the IRS receives a copy.
If you are entitled to keep the interest, you report it on Schedule B (Interest and Ordinary Dividends) and it flows to your Form 1040. Even if the amount is under $10 and no 1099-INT is issued, the interest is still taxable income — you just report it without a form.
If your state requires you to pay that interest to tenants, the 1099-INT may still come to you — but the income is not yours. In that situation, the prudent approach is to issue the tenant a corrected 1099-INT (or simply pass along the bank's 1099 showing their entitlement) and document in your records why you are not reporting it as your income. Some practitioners also attach a brief explanatory note to their return if the amounts are significant.
For landlords who commingle security deposits in a general business checking account rather than a separate account, the interest earned on the entire account balance — including the deposit funds — is still reportable income. The IRS has no way to carve out what portion of a commingled balance "belonged" to tenants if you are entitled to keep it all, and the bank will issue a 1099-INT for the full account interest.
When a deposit becomes income: the forfeiture rules
The deposit — or any portion of it — becomes ordinary rental income in the year you are entitled to keep it. The two most common scenarios are:
Applied to unpaid rent: If the tenant fails to pay last month's rent and you apply the security deposit to cover it, the applied amount is rental income in the year of application. It is not a capital event or a gain — it is income from the rental activity, reported on Schedule E (or on the entity's business return if you hold the property in an LLC or partnership).
Applied to property damage: If the tenant damages the unit and you apply the deposit to repairs, the applied amount is also income. The twist is that the qualifying repair costs — the actual amounts you spend restoring the property — are deductible as ordinary rental expenses in the same year. The two entries wash out for net income, but both sides must still be reported. You cannot simply ignore the transaction because it nets to zero.
What if the deposit exceeds the actual damage? Say you hold a $2,500 deposit and the tenant causes $1,800 of damage. You can keep $1,800 (income, offset by repair deduction) and must return $700. The $700 returned is not a deduction — it was never income in the first place.
Partial forfeitures and mixed applications
Many lease-end situations involve a mix: some of the deposit covers unpaid rent, some covers cleaning, some is returned. The tax treatment follows each dollar to its destination.
Example: a tenant leaves with two months of unpaid rent ($2,400) and significant damage ($900 in repairs). The security deposit was $3,000. You apply $2,400 to unpaid rent (rental income, no offsetting deduction), $600 to repairs (income, plus $600 deductible repair expense), and return nothing. Total income recognized: $3,000. Net taxable effect: $2,400 (the rent portion) plus $600 − $600 (the damage portion nets to zero) = $2,400 net additional taxable income after expenses.
Keep records of exactly how each dollar of the deposit was applied. A written move-out statement, repair invoices, and receipts support both the income inclusion and any offsetting deductions if the IRS asks.
Worked numeric example: full deposit lifecycle
A landlord in a state with no interest-remittance requirement collects a $3,000 security deposit from a tenant who signs a 12-month lease at $1,500 per month.
The deposit is placed in a dedicated savings account earning 4.5% annual percentage yield.
Year 1 (while tenant occupies):
Interest earned: $3,000 × 4.5% = $135
The landlord reports $135 as ordinary interest income on Schedule B. The 12 months of rent ($18,000) is reported on Schedule E as usual.
Scenario A — clean move-out:
Tenant leaves the property in good condition, pays all rent. Landlord returns the full $3,000 deposit. No income at lease end (the deposit was never recognized as income). Year 2 interest, if any, is also reported by the landlord.
Scenario B — partial forfeiture for unpaid rent:
Tenant skips the last month's rent. Landlord applies $1,500 of the deposit to the missed rent payment and returns $1,500.
Income recognized in the year of application: $1,500 (rental income on Schedule E).
The remaining $1,500 returned to the tenant creates no income event.
Scenario C — forfeiture for repairs:
Tenant causes $800 of documented damage (carpet replacement and wall patching). Landlord applies $800 of the deposit to repairs and returns $2,200.
Income recognized: $800 (rental income on Schedule E).
Deductible repair expense: $800 (ordinary rental repair expense on Schedule E).
Net Schedule E effect: zero — but both the $800 income and the $800 expense must be reported; you cannot omit both sides.
Recordkeeping for security deposit tax compliance
Good records protect you if the IRS questions why a deposit was not reported as income at receipt, or why you later recognized it. Keep the following for each tenancy:
- The signed lease showing the deposit amount, the purpose (refundable security deposit), and any interest-accounting terms
- Bank statements showing the deposit in a segregated account (or a notation if it was commingled)
- Annual statements of interest earned, with 1099-INT forms from the bank
- A move-out checklist or inspection report documenting the property's condition
- Receipts or invoices for any repairs funded by the deposit
- Documentation of any unpaid rent — late notices, ledger entries — supporting the application of the deposit
- A written accounting to the tenant showing how the deposit was applied and any amount returned, as required by most state landlord-tenant statutes
The IRS assessment period is generally three years from the filing date, but a substantial understatement of income can extend it to six years. Keep security deposit records for at least six years after the tax year in which the deposit was finally applied or returned — not just the lease year.
Frequently asked questions
Is a security deposit taxable income when received?
No. A security deposit held with the obligation to return it is not gross income when received. It is a refundable liability. It becomes ordinary income only when you are entitled to keep it — typically when you apply it to unpaid rent or property damage at the end of the tenancy.
Is interest earned on a security deposit taxable?
Yes, if you are entitled to keep it. If your state allows you to retain the interest on the security deposit, that interest is ordinary income in the year earned. If your state requires you to remit the interest to the tenant, the tenant reports it and you do not include it in your income.
What happens tax-wise when a tenant forfeits the security deposit?
The forfeited portion becomes rental income in the year you apply it. If used for unpaid rent, it is rental income with no offsetting deduction. If used for repairs, it is rental income, but the actual repair costs are a deductible rental expense — both sides must be reported even though they may net to zero.
Which tax form do I use to report deposit interest?
If the deposit is in a bank account issuing a Form 1099-INT, report the interest on Schedule B; it flows to Form 1040. If you treat deposit interest as incidental rental income, some landlords include it on Schedule E. Either way, it is ordinary income taxed at your marginal rate — the form used does not change the tax.
Do I report deposit interest if my state requires me to pay it to the tenant?
No. When state law requires you to remit the interest to the tenant, the income belongs to the tenant from the moment it accrues. The tenant reports it on Schedule B. You act as a conduit — no income inclusion and no deduction for the payment to the tenant.
