A refundable security deposit is an asset to the party who paid it and a liability to the party who holds it. Whether a security deposit is an asset or a liability depends on which side of the transaction you sit on: the payer controls a future right to get the cash back, while the recipient owes that cash back unless the payer breaches the agreement. That dual classification drives every journal entry, balance sheet placement, and closing entry that follows.
Recording the Deposit as an Asset (Payer’s Side)
If you paid the deposit, you own a future economic benefit: the contractual right to reclaim the cash. Under the FASB’s Conceptual Framework, an asset is a “probable future economic benefit obtained or controlled by a particular entity as a result of past transactions or events.”1FASB. Statement of Financial Accounting Concepts No. 6 A refundable deposit fits that definition. You transferred cash, you control the right to get it back, and that right came from a past event such as signing the lease.
The initial entry is a reclassification, not a gain or loss. Debit an asset account, often titled Security Deposits or Security Deposit Receivable, and credit Cash for the same amount. A $2,500 commercial lease deposit raises one asset line by $2,500 and lowers another by $2,500. Nothing hits the income statement.
Where the deposit lives on the balance sheet depends on timing. If the underlying agreement runs 12 months or less, the deposit is a current asset. If it stretches beyond a year, it goes into noncurrent assets, typically under a heading like Other Assets.2AccountingCoach. Is a Security Deposit a Current Asset That one-year threshold is the standard GAAP cutoff. When a noncurrent lease enters its final 12 months, reclassify the deposit to current.
Recording the Deposit as a Liability (Recipient’s Side)
If you received the deposit, you hold someone else’s money. Under FASB’s framework, a liability is a present obligation to transfer an economic benefit, and a refundable deposit creates exactly that obligation. You must either return the cash or justify keeping it by documenting damages or a breach. Until one of those things happens, the money is not revenue.
Debit Cash and credit a liability account, usually called Refundable Security Deposits or Security Deposits Payable, for the full amount. A $2,500 receipt raises cash and liabilities by the same amount, so net worth doesn’t move.
The current-versus-noncurrent split mirrors the payer’s. A deposit on a one-year lease sits in current liabilities. A deposit on a multi-year agreement starts as noncurrent and moves to current once the lease has less than 12 months to run.
Roughly half the states require landlords to hold residential security deposits in a dedicated bank account, separate from operating funds, and about 15 states require the account to earn interest for the tenant’s benefit. Even where the law doesn’t mandate segregation, keeping deposits in a separate account makes the accounting cleaner and prevents commingling that could trigger penalties.
Closing Entries When the Agreement Ends
The deposit’s conditional nature resolves when the lease or contract ends. At that point both sides clear the balances from their books. The entries depend on whether the deposit comes back in full, in part, or not at all.
Full Refund
The payer debits Cash and credits Security Deposit Receivable for the full amount. One asset converts back into another, and the income statement doesn’t move. The recipient debits Refundable Security Deposits and credits Cash. The obligation is settled and both balance sheets are clean.
Partial Refund
This is the most common outcome. Assume a $2,000 deposit, $500 retained for repairs, and $1,500 returned.
The recipient makes a split entry: debit the $2,000 liability to zero, credit Cash for $1,500, and credit a revenue account (often Other Income or Damages Revenue) for the $500 retained. That $500 becomes taxable income in the year retained.3Internal Revenue Service. Publication 527 (2025), Residential Rental Property
The payer books the mirror image: debit Cash for $1,500, debit an expense account such as Repairs Expense for $500, and credit Security Deposit Receivable for the full $2,000. The $500 expense reduces net income.
Full Forfeiture
If the entire deposit is forfeited, the recipient debits the full liability and credits revenue for the same amount. The whole sum is income for book and tax purposes. The payer debits an expense account for the full amount and credits Security Deposit Receivable to zero out the asset. The entire deposit becomes a recognized loss.
When a Security Deposit Becomes Taxable Income
The IRS draws a clear line. A security deposit you intend to return is not income when you receive it.4Internal Revenue Service. Topic No. 414, Rental Income and Expenses That matches the liability treatment above: you’re holding someone else’s money, not earning it.
The deposit flips to taxable income in the year you decide to keep any portion. Publication 527 identifies three situations:3Internal Revenue Service. Publication 527 (2025), Residential Rental Property
- Tenant breaks the lease and you keep part or all of the deposit. Include the retained amount in that year’s income.
- Tenant damages the property and you keep funds to cover repairs. If you normally deduct repair costs as expenses, include the retained amount in income; the offsetting repair deduction nets the two. If you don’t normally deduct repairs, you don’t include the retained deposit either.
- The deposit is designated as the final month’s rent. That is advance rent, not a true security deposit. Include it in income the year received, not the year applied.4Internal Revenue Service. Topic No. 414, Rental Income and Expenses
That last point catches many landlords off guard. If the lease says the deposit “will be applied to the final month,” the IRS treats it as rent paid in advance. The accounting also changes at receipt: credit a revenue account, not a liability account. Mislabeling advance rent as a security deposit doesn’t change the tax result, because substance controls over the label.
Interest on Security Deposits
In the states that require interest on residential security deposits, the landlord accrues that interest as both an expense and an increase in the liability. Debit Interest Expense and credit Refundable Security Deposits for the accrued amount. The rate and payment frequency vary by jurisdiction; the accounting principle does not.
On the tenant’s side, accrued interest increases the asset. Debit Security Deposit Receivable and credit Interest Income for the same amount. Record the accrual whether the landlord pays the interest out annually or credits it against the final refund. Accrual accounting doesn’t wait for cash to change hands.
Writing Down a Deposit You May Not Recover
A deposit sitting on your books as an asset assumes eventual collection. When that assumption stops being reasonable, because the landlord files for bankruptcy, the counterparty shuts down, or a commercial tenant becomes insolvent, the asset needs a write-down.
The mechanics are straightforward: debit a loss account, such as Loss on Security Deposit, and credit Security Deposit Receivable for the amount no longer expected to come back. If you paid $5,000 and now expect to recover $2,000, recognize a $3,000 loss and reduce the asset to $2,000. The write-down flows through the income statement in the period recognized.
FASB’s lease guidance offers a useful analogy. Under ASC 842, maintenance deposits paid under a lease are accounted for as deposit assets, and the lessee must evaluate whether return of the deposit is “probable.” When it’s no longer probable, the amount is recognized as an expense.5FASB. Leases (Topic 842) – ASU 2016-02 The same logic applies to any refundable deposit: keep testing whether recovery is likely and adjust the carrying value when it isn’t.
In residential settings this kind of impairment is rare. Most tenants either get their deposits back or lose them to documented damage. For larger commercial deposits, especially with financially weaker counterparties, the review matters more.
