Are Security Deposits Taxable Rental Income?

For U.S. federal income tax, a security deposit you expect to return generally is not rental income when you receive it. An amount you later keep because the tenant does not meet the lease terms is income in the year you keep it. Money intended from the start as the final rent payment is advance rent, even if someone calls it a deposit. The IRS rental-income guidance makes these distinctions.

That answers a tax question, not whether you are legally entitled to keep the money. The examples below explain the difference through three fictional payment histories. This is general educational information, not advice for preparing your individual return.

The same amount can have different treatment

Each example starts with $1,200. Assume a U.S. residential rental operated for profit without personal use, and a landlord using the cash method. Year 1 and Year 2 are illustrative tax years, not forecasts of future tax rules. Other rent receipts and expenses are left out so we can follow this one payment.

IRS Publication 527 explains that cash-method taxpayers generally report income when actually or constructively received. It separately addresses refundable deposits and advance rent. For advance rent, the IRS says to report it in the year received regardless of the period covered or accounting method.

Reporting income does not give permission to retain a deposit

Two different questions can arise: “May I keep this amount?” and “How is an amount I keep treated for tax?” The IRS guidance above addresses the second. It does not establish a landlord’s right to charge the tenant, set a deduction amount, or replace applicable deposit-handling requirements.

Do not use the $300 example as a suggested charge. The facts, lease, and applicable law must support an actual retention. If entitlement, timing, or a dispute remains unresolved, take the records to the appropriate legal or tax professional rather than forcing the situation into one of these simple examples.

Keep records that explain what happened to the money

A bank entry labeled “deposit” does not tell the whole story. Preserve the agreement describing the payment, the receipt date and amount, the tenant ledger, and any subsequent refund, application, or retention documentation. These records let you explain which of the three situations you actually have.

For the partial-refund example, a useful record connects the original $1,200 receipt to the $900 refund and the documented $300 retention. For the prepaid-rent example, it connects the original receipt to the later rent period without recording a new cash receipt. These are practical recordkeeping examples, not a required accounting system.

If you have recently taken over management, our property management handover guide explains which deposit balances and supporting records to request. A transfer between managers should not erase the history of what the tenant originally paid or why.

Use guidance for the return you are preparing

The IRS publication available when this article was checked on October 22, 2026 was Publication 527 (2025). That is its edition, not a claim that a 2026 edition has been released. Check the current publication and instructions for the return you are preparing, and confirm how they apply to your facts.

Start with the purpose of the payment and follow what actually happened to it. A refundable deposit, a retained amount, and advance rent can look alike on a bank statement while belonging in different places in your tax records.
