The tax treatment of non-refundable deposits turns on two questions: did the deal close or fall apart, and was the deposit for business, investment, or personal purposes? For the person who holds the money, a deposit usually is not income the day it arrives. It becomes income when the transaction closes and the deposit is applied to the price, or when the payer walks away and forfeits it. For the person who paid the deposit, a forfeiture may be a fully deductible ordinary loss, a capital loss subject to annual limits, or a personal expense with no tax benefit at all.
When the Recipient Owes Tax
A deposit held to guarantee someone’s performance generally does not count as income the moment it hits the bank account. Recognition is triggered by one of two events: the underlying deal closes and the deposit is folded into the purchase price, or the payer forfeits the money. Which year that income lands in depends on the recipient’s accounting method and on whether the funds were truly restricted.
Cash Method vs. Accrual Method
A cash-basis business usually treats payments as income when received. A deposit can escape immediate taxation if it genuinely secures performance and the recipient has a real obligation to return it under defined conditions. If the recipient has unrestricted use of the money from day one, the IRS is likely to treat the payment as current income no matter what the contract calls it.
Accrual-method taxpayers apply a different test. Income is recognized when the right to it becomes fixed and the amount is determinable. A deposit that still depends on the payer’s future performance is not yet fixed, so accrual-method businesses can often defer recognition until closing or forfeiture. That tends to align the tax reporting with the economic substance of the deal.
Constructive Receipt Can Override the Label
Even a payment labeled a deposit or held nominally in escrow can be taxed immediately under the constructive receipt doctrine. Under Treasury Regulation 1.451-2, income counts as received when it is credited to the taxpayer’s account, set apart for them, or otherwise made available to draw on at any time. The question is whether access is subject to substantial limitations or restrictions. If not, the money is taxable in the year it became available, even if the taxpayer chose not to touch it.1GovInfo. Treasury Regulation 1.451-2 – Constructive Receipt of Income
This comes up most often when a contract uses the word “deposit” but the funds go straight into the recipient’s operating account with no obligation to segregate or return them. In that situation, the constructive receipt rules can trump the contract’s language and pull the money into current income.
The One-Year Deferral Under Section 451(c)
Accrual-method taxpayers who receive advance payments for goods or services can elect to defer a portion of the income to the following tax year. The Tax Cuts and Jobs Act codified this one-year deferral in IRC Section 451(c).2Office of the Law Revision Counsel. 26 USC 451 – General Rule for Taxable Year of Inclusion
The mechanics: whatever portion of the advance payment the taxpayer books as revenue on an applicable financial statement in the year of receipt must also be included in taxable income that year. The remainder shifts to the next tax year, and no further.
The deferral is not available for every kind of advance payment. Rent, insurance premiums, payments tied to financial instruments, and certain warranty payments are excluded from the definition of “advance payment” under Section 451(c)(4)(B).3Office of the Law Revision Counsel. 26 US Code 451 – General Rule for Taxable Year of Inclusion Advance rent in particular is always taxable in the year received regardless of accounting method.
Deposit or Prepaid Fee
Tax treatment hinges on what the payment actually does, not what the parties call it. A true non-refundable deposit secures the payer’s commitment and will be applied against the final price at closing. That structure supports deferral. A prepaid fee gives the recipient immediate, unrestricted use of the money in exchange for a future service or product, and that points toward immediate income recognition.
Courts and the IRS look at the economics. Does the recipient have any obligation to return the funds? Are the funds segregated or commingled with operating revenue? Is the payment tied to a specific future performance, or is it simply compensation received early? Those answers determine whether a payment functions as a deposit or a fee.
What the Payer Can Deduct
If the deal closes, the deposit is not a separate deductible expense. It merges into the total cost of whatever the payer acquired. A deposit on a capital asset becomes part of that asset’s basis for depreciation. A deposit on inventory folds into cost of goods sold.
The harder question is what happens when the deal collapses and the deposit is forfeited. The answer depends almost entirely on why the deposit was made in the first place.
Business Forfeitures: Ordinary Loss
When a business forfeits a non-refundable deposit, the loss is generally deductible in the year the forfeiture becomes final. IRC Section 162 allows a deduction for ordinary and necessary expenses paid in carrying on a trade or business.4Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses IRC Section 165 separately allows a deduction for losses incurred in a trade or business or in any transaction entered into for profit.5Office of the Law Revision Counsel. 26 US Code 165 – Losses
The forfeiture is treated as an ordinary loss, which offsets ordinary income dollar for dollar with no annual cap. The business must have genuinely intended to use the asset or service in its operations, and the loss is claimed in the tax year the transaction is definitively abandoned and the right to recover the deposit is extinguished.
Personal Forfeitures: No Deduction
A forfeited deposit on something personal is a non-deductible personal expense. Section 165(c) limits individual loss deductions to losses from a trade or business, losses from profit-seeking transactions, and certain casualty or theft losses. A forfeited deposit on a vacation rental, a wedding venue, or a home purchase that fell through does not fit any of those categories.5Office of the Law Revision Counsel. 26 US Code 165 – Losses
The money is gone with no tax benefit. The business-versus-personal distinction is the single most important factor for the payer, and it is determined by the facts at the time the deposit was made, not by what happens afterward.
Investment Forfeitures: Capital Loss Limits
A forfeited deposit on an investment asset (rental property a buyer intended to hold for income, for example) produces a capital loss rather than an ordinary loss. Individual taxpayers can only deduct capital losses to the extent of their capital gains, plus up to $3,000 of ordinary income per year, or $1,500 if married filing separately.6Office of the Law Revision Counsel. 26 US Code 1211 – Limitation on Capital Losses
Any capital loss exceeding that limit carries forward. Short-term losses carry forward as short-term, and long-term losses carry forward as long-term.7Office of the Law Revision Counsel. 26 USC 1212 – Capital Loss Carrybacks and Carryovers For a large forfeited deposit with no offsetting capital gains, the tax benefit can stretch across several years.
Mixed-Use Assets
If a deposit was placed on a property that would have served both business and personal purposes (a home with a dedicated office, say), the forfeited amount must be allocated. Only the business portion qualifies as a deductible loss. The personal portion gets no deduction.
Real Estate Earnest Money
Earnest money in a real estate transaction is typically held in a neutral escrow account until closing. While the money sits in escrow, neither buyer nor seller owes tax on it. The tax event is triggered by either the closing or the forfeiture.
If the deal closes, the earnest money is applied to the purchase price and becomes part of the buyer’s basis in the property. No separate income or deduction arises. If the buyer forfeits the earnest money, the seller reports the full amount as ordinary income, not capital gain. Federal courts have consistently treated forfeited deposits as ordinary income because no sale or exchange of a capital asset actually took place.8Internal Revenue Service. Topic No. 414, Rental Income and Expenses
For the buyer, the deduction question tracks the intended use of the property. A buyer who planned to live in the home gets no deduction. A buyer who intended to use the property for business or investment may claim a loss, subject to the ordinary-versus-capital rules above.
Option Payments Are Different
A non-refundable option payment buys the right to purchase property within a set period without committing to the purchase. IRC Section 1234 governs the tax treatment.9Office of the Law Revision Counsel. 26 US Code 1234 – Options to Buy or Sell
For the option holder, the rules are straightforward. If the option is exercised, the payment becomes part of the property’s cost basis. If the option expires unexercised, the holder recognizes a loss with the same character the underlying property would have had. A lapsed option on what would have been a capital asset produces a capital loss.
For the person who granted the option, the treatment depends on the property type. Section 1234(b) applies only to options on stocks, securities, and commodities, treating gains on lapsed options as short-term capital gains for the grantor. Real estate is not covered. When a real estate option lapses, the property owner who keeps the option payment recognizes ordinary income, because no sale or exchange occurred. If the option is exercised, the payment folds into the total sale proceeds, and the owner recognizes capital gain or loss on the overall transaction, assuming the property was a capital asset.9Office of the Law Revision Counsel. 26 US Code 1234 – Options to Buy or Sell
Landlord Deposits: Security vs. Advance Rent
Deposits in the rental context split into two categories with sharply different tax consequences.
A true security deposit is not income to the landlord when received, as long as the landlord has an obligation to return it when the tenant meets the lease terms. Income is recognized only when the landlord keeps part or all of the deposit because of a lease violation. The amount retained becomes taxable income for that year.10Internal Revenue Service. Publication 527 (2025), Residential Rental Property
The label does not control. If a payment called a “security deposit” is actually designated as the final month’s rent, the IRS treats it as advance rent.10Internal Revenue Service. Publication 527 (2025), Residential Rental Property
Advance rent is any amount received before the rental period it covers. It is always included in gross income in the year the landlord receives it, regardless of the period covered and regardless of whether the landlord uses the cash or accrual method.8Internal Revenue Service. Topic No. 414, Rental Income and Expenses A landlord who collects the last month’s rent at lease signing reports that income immediately, even though the rental period it covers could be years away.
Any non-refundable fee collected at the start of a lease (a move-in fee, an administrative fee, or any similar charge) follows the same logic. If the landlord has no obligation to return it, it is income in the year received.
