In accounting, a commission is a payment tied to closing a sale or delivering a specific service: the business paying it records an expense (or, in some cases, an asset), and the person earning it records revenue. The entries look simple on paper, but the timing, classification, and tax treatment depend on the accounting method in use, the length of the underlying contract, and whether the earner is an employee or an independent contractor. Commissions sit at the crossroads of revenue recognition, payroll tax, and wage-and-hour law, which is why the rules are more layered than most first-time bookkeepers expect.
How the Commission Structure Shapes the Entry
Before any journal entry gets written, the structure of the commission agreement determines what the numbers look like and when they become knowable.
- A flat fee pays a fixed dollar amount per sale, so the amount is known the moment the deal closes.
- A percentage-based commission takes a cut of the transaction value. Real estate agents are the classic case, earning a share of the sale price at closing.
- A tiered rate rises after a volume threshold. A rep might earn 5% on the first $100,000 in sales and 8% above that, which can retroactively change the rate on earlier sales once a higher tier is reached.
- A draw against commission gives the salesperson a guaranteed advance each pay period. A recoverable draw is booked initially as a receivable from the employee, not compensation expense, until actual commissions catch up.
- A residual commission pays out for as long as the customer relationship continues. Under current revenue recognition standards, the portion tied to ongoing service obligations is recognized over the service period rather than all at once.
Whichever structure applies, the accounting turns on two bigger questions: whether to expense the commission immediately or capitalize it, and when the earner can recognize the income.
Recording Commission Expense Under Accrual Accounting
Under accrual accounting, the paying business records commission expense when the sale happens, not when the check clears. This follows the matching principle: the cost of generating revenue belongs in the same period as the revenue. If a salesperson earns a $2,500 commission in December but payroll runs the payment in January, December’s books need a debit to commission expense and a credit to commissions payable. Skip that entry and December’s profit is overstated while January’s is understated.
The commissions payable balance sits as a current liability on the balance sheet until payment. At year-end, this liability can be substantial for companies with large sales teams, and auditors will look at it closely. When the payment goes out, the entry is a debit to commissions payable and a credit to cash.
A cash-basis business records the expense only when the money leaves the account. It’s simpler, but it creates timing mismatches: a December sale might not produce a recorded expense until January. Cash-basis treatment is limited to smaller businesses that meet IRS gross receipts thresholds. Most businesses with inventory, meaningful credit sales, or outside investors use accrual specifically to avoid those distortions.
When Commissions Must Be Capitalized Instead
This is where many companies get commission accounting wrong. Under ASC 340-40, sales commissions that are incremental costs of obtaining a customer contract must be capitalized as an asset if the company expects to recover them. “Incremental” means the cost would not have been incurred if the contract hadn’t been won. A commission paid only on closed deals is the textbook example.
Once capitalized, the asset is amortized over the period the company expects to benefit from the customer relationship. A $10,000 commission for a three-year service contract doesn’t hit the income statement all at once. The company books a $10,000 asset and expenses roughly $278 a month over 36 months. The amortization period can run longer than the initial contract if renewals are expected and the commission doesn’t reset on renewal.
There is a practical expedient that catches most smaller deals: if the amortization period would be one year or less, the company can expense the commission immediately. A one-time product sale with no ongoing contract? Expense it. A multi-year SaaS subscription where the rep earns commission only on the initial deal? Capitalize and amortize. This distinction trips up a lot of growing companies, particularly in software and professional services where contract terms routinely exceed twelve months.
Costs that would have been incurred regardless of whether the contract was obtained, such as base salaries or general marketing spend, are always expensed as incurred. They never get capitalized under this rule.
Recognizing Commission Income on the Earner’s Side
From the earner’s perspective, commission income is recognized when the service is fully performed and the right to payment is established. In most sales scenarios, that point arrives when the deal closes or a binding contract is executed. The earner debits accounts receivable and credits commission revenue, even before the cash arrives.
Two conditions have to hold before recognizing the revenue: the amount must be determinable, and collection must be reasonably assured. If either fails, recognition is deferred. A real estate agent doesn’t book revenue when a buyer submits an offer. The entry waits for closing, when the transaction is final and the commission is fixed.
Cancellations force reversing entries. If a deal falls through after the receivable has been booked, both the receivable and the revenue come off the books. Earners with high cancellation rates usually maintain a reserve or allowance for anticipated reversals rather than chasing individual entries after the fact.
Payroll and Tax Reporting
Withholding on Employee Commissions
The IRS classifies commissions paid to employees as supplemental wages, which triggers withholding rules that differ from regular payroll.1Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide Employers pick between two methods for federal income tax:
- The flat 22% method applies a fixed 22% to the commission payment, provided the employer withheld income tax from the employee’s regular wages in the current or preceding calendar year. Most payroll systems default to this.
- The aggregate method combines the commission with the employee’s regular wages for that pay period and withholds as if the total were one payment. This often produces higher withholding because the combined check lands in a higher bracket.
When an employee’s supplemental wages exceed $1 million in a calendar year, the excess is subject to mandatory 37% withholding regardless of the employee’s W-4.1Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide Commissions are also subject to Social Security tax (6.2% each from employer and employee, up to the $184,500 wage base in 2026) and Medicare tax (1.45% each, uncapped).2Social Security Administration.

W-2 vs. 1099-NEC Reporting
Employees receive commissions through payroll, and the total shows up on Form W-2 as part of wages. Independent contractors receive a Form 1099-NEC if total payments reach $2,000 or more in a tax year. That threshold rose from $600 for tax years beginning after 2025, a significant change for 2026. The 1099-NEC must be furnished to the recipient and filed with the IRS by January 31.3Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns
Independent contractors report commission income on Schedule C of Form 1040.4Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) They also owe self-employment tax: 12.4% for Social Security on net earnings up to $184,500, plus 2.9% for Medicare on all net earnings.2Social Security Administration. Contribution and Benefit Base The combined 15.3% rate applies fully only up to the Social Security wage base. Above it, only the 2.9% Medicare portion continues, and earners with net self-employment income above $200,000 (single filers) owe an additional 0.9% Medicare surtax.5Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Because no one withholds taxes for contractors, estimated payments are due quarterly on April 15, June 15, September 15, and the following January 15.6Internal Revenue Service.

Where Commissions Land on Financial Statements
On the paying company’s income statement, commission expense usually appears under selling, general, and administrative expenses. When a commission is tied directly to producing a specific product, it may instead sit in cost of goods sold, which affects gross profit rather than operating profit. The classification changes how investors and analysts read the company’s margins.
Unpaid commissions at period end appear as a current liability called commissions payable. Capitalized commission costs under ASC 340-40 appear as an asset, usually inside other current assets or other noncurrent assets depending on the remaining amortization period. For the earner, commissions show up as revenue on the income statement, categorized as primary operating revenue when commissions are the core business.
Handling Commission Clawbacks
Clawbacks happen when a salesperson has to return commissions already earned, usually because the customer cancelled, returned the product, or defaulted on payment. On the company’s books the reversal is straightforward: reduce commission expense and reduce the amount owed to (or recover from) the salesperson. The tax side for the person repaying is harsher than most expect.
Employees who repay commissions used to deduct the repayment as a miscellaneous itemized deduction. The Tax Cuts and Jobs Act suspended that deduction starting in 2018, and later legislation made the suspension permanent. An employee who earned and paid tax on a $15,000 commission in 2025, then repaid it in 2026, generally cannot deduct the repayment as an itemized deduction.
The main relief valve is Section 1341 of the Internal Revenue Code, which applies when a repayment exceeds $3,000.7Office of the Law Revision Counsel. 26 USC 1341 – Computation of Tax Where Taxpayer Restores Substantial Amount Held Under Claim of Right The taxpayer runs the tax calculation two ways: once taking the deduction in the current year, and once computing the reduction that would have resulted from never reporting the income in the prior year. They pay whichever is lower. Section 1341 doesn’t always produce a perfect offset, especially if tax rates shifted between years, but it prevents the worst outcomes.
Companies with meaningful return or cancellation rates should build a reserve for anticipated clawbacks at the time commissions are first recorded. Waiting for cancellations to reverse individual entries produces lumpy expense recognition that misrepresents the true cost of the sales operation.
Overtime Rules Ride Along With Commissions
Paying an employee on commission does not automatically exempt them from overtime. Under the Fair Labor Standards Act, commissions must be folded into the employee’s regular rate of pay when calculating overtime.8eCFR. Title 29 Labor – Part 778 Subpart B – Principles for Computing Overtime Pay Based on the Regular Rate The employer divides total earnings (including commissions) by total hours worked to find the regular rate, then pays an additional half-time premium for overtime hours. When commissions are calculated after the pay period ends, the employer owes retroactive overtime adjustments for any weeks where the employee cleared 40 hours.
A narrow exemption exists under Section 7(i) of the FLSA for employees of retail or service establishments, but only if all three tests are met: the employer qualifies as a retail or service establishment (at least 75% of annual sales not for resale and recognized as retail in the industry), the employee’s regular rate exceeds 1.5 times the minimum wage in every workweek with overtime, and more than half of the employee’s earnings over a representative period come from commissions.9U.S. Department of Labor. Fact Sheet 20 – Employees Paid Commissions By Retail Establishments Who Are Exempt Under Section 7(i) From Overtime Under the FLSA A slow sales month can push commissions below 50% of total pay and retroactively destroy the exemption for that period. Employers relying on 7(i) need to run the math every pay period rather than assume it holds.
