Are security deposits taxable income for STR hosts?

Security deposits held with the intent to return them to guests are not taxable income when received. They become taxable income only when you retain them — for example, to cover property damage or an unpaid balance. At the moment of retention, the amount you keep is reportable income on Schedule C.

When must I report a retained security deposit as income?

Under the cash method of accounting, you report a retained security deposit as income in the tax year you decide to retain it. If you receive a $500 deposit in December 2025 and decide to keep it for damages in February 2026, the income is reported on your 2026 return.

Does Airbnb's damage waiver work the same as a security deposit for tax purposes?

No. Airbnb's AirCover damage protection is funded by Airbnb, not by a guest security deposit held by you. Payouts from AirCover for property damage are generally considered reimbursement income. Host-managed security deposits (collected and held by you outside the platform) follow the standard trust account rules — taxable only when retained.

Security Deposit Income: When Is It Taxable for STR Hosts?

Security deposits received from STR guests are not taxable income when collected — they are held in trust as a liability until the guest checks out. The deposit becomes taxable income only at the point you decide to retain it, either in full or in part, for damages, unpaid amounts, or other claims. Under IRC §61(a) and Treasury Regulation §1.61-8, the tax treatment follows the actual economic transfer of the funds.

The Trust Account Principle

The fundamental rule for security deposits comes from long-established tax law: a security deposit that you are obligated to return is a loan from the guest, not income to you. You hold it in trust. It is a liability on your books, not revenue.

Treas. Reg. §1.61-8(b) confirms: "Gross income includes advance rentals, which must be included in income for the year of receipt regardless of the period covered or the method of accounting employed by the taxpayer." However, true security deposits (refundable, held in trust) are distinguished from advance rental payments and are not included in income when received.

Key Distinction

If you receive a "last month's rent" or a "non-refundable cleaning deposit" — an amount you are not expected to return — that is taxable income when received, not a security deposit. Only refundable deposits held in trust qualify for the trust account treatment. The intent at the time of collection determines the classification.

When Does the Deposit Become Taxable?

A security deposit becomes taxable income at the point you determine you will retain it. For cash-method taxpayers (most individual STR hosts), this means the tax year in which you make the retention decision:

Full retention: Guest causes significant damage and you retain the full $500 deposit — the full $500 is income in the year you retain it
Partial retention: You retain $200 of a $500 deposit for broken furniture — $200 is income, $300 is returned and never becomes income
Cross-year retention: Deposit received in December 2025, damage claim decided in February 2026 — income is reported in 2026, the year of retention

Year-End Timing

Be careful about year-end stays with pending damage decisions. If you received a deposit in December and the guest checks out on January 2, your retention decision happens in the new year. The income, if any, belongs on next year's return. Don't include pending deposits in your current-year gross income.

Documenting Damage Claims

When you retain a security deposit, solid documentation protects you from disputes and supports your income reporting:

Timestamped photos: Photograph property condition immediately before and after each guest stay
Written claim notice: Document your damage claim decision in writing, including the date, amount, and nature of damage
Cost documentation: Receipts or invoices for repairs funded by the deposit
Communication records: Any correspondence with the guest about the damage claim

This documentation serves double duty: it supports your retention decision if the guest disputes it, and it establishes the date of retention for tax reporting purposes.

Platform Security Deposits vs. Host-Managed Deposits

Airbnb and Platform-Level Deposits

Airbnb's security deposit feature (when you set a security deposit on your listing) works through Airbnb's resolution center. Airbnb may place a pre-authorization hold on the guest's credit card or release funds from a reservation. The tax treatment depends on how the payout is structured — amounts paid to you from the guest's deposit are taxable when received.

AirCover Damage Protection

AirCover is Airbnb's own program that reimburses hosts for qualifying damage. Payouts from AirCover come from Airbnb, not from a guest security deposit. These reimbursements are generally income to you when received, as they compensate for actual damage (you may have a corresponding repair expense deduction). The characterization depends on the nature of the damage and whether repairs were deductible.

Direct Security Deposits (Off-Platform)

Some direct-booking STR hosts collect security deposits directly via check, ACH, or credit card. These follow the trust account principle strictly: not income when received, income when retained. Some states require security deposits to be held in separate escrow or trust accounts — consult your state's landlord-tenant laws even for STRs.
