Yes. Selling expense is an operating expense. On a standard income statement, selling costs sit inside the operating expense block along with general and administrative costs, below gross profit and above operating income. That classification matters for two reasons: it shapes how profitability is reported, and it means these costs are generally deductible in the year they’re incurred under Internal Revenue Code Section 162 rather than capitalized and spread over future years.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
Where Selling Expenses Sit on the Income Statement
An income statement draws a hard line between the costs of producing what a company sells and the costs of running everything else. Raw materials and factory labor are cost of goods sold. Net revenue minus cost of goods sold gives gross profit. Everything below that line, until you reach interest and taxes, is an operating expense.
Operating expenses generally break into three buckets: selling expenses, general and administrative expenses, and depreciation or amortization of assets used in operations. Many companies combine the first two into a single line labeled SG&A (selling, general, and administrative). Others break them out. Either way, selling costs land in the operating expense block.
The practical distinction between the selling piece and the G&A piece comes down to one question: does the cost exist because the company is trying to generate sales, or because the company simply needs to exist as an organization? A regional sales manager’s salary is a selling expense. The CFO’s salary is a G&A expense. Both are operating expenses.
What Counts as a Selling Expense
Selling expenses cover every cost tied to finding customers, closing deals, and delivering the product. If the expense wouldn’t exist without a sales effort, it’s almost certainly a selling expense.
- Sales commissions, whether percentage-based or flat, paid on closed deals.
- Advertising and marketing, including digital ad spend, media placement, trade show costs, and promotional materials.
- Salaries and benefits for sales staff, sales managers, and marketing team members.
- Travel: airfare, hotels, meals, and transportation incurred while pursuing new business.
- Outbound shipping, often called “freight-out,” which is tied to completing the sale. Inbound freight is different — that becomes part of inventory cost.
- Bad debt expense, generally classified as a selling expense because the uncollectible account arose from the sales function.
Many of these costs are variable. Commissions and shipping scale with sales volume, so a jump in selling expenses alongside flat revenue is a warning sign. Growing revenue with stable selling expenses points the other way.
Selling Expense vs. Capital Expenditure
This is where classification mistakes actually happen, and it’s the reason the operating expense label matters on a tax return. Operating expenses are fully deductible in the year they’re incurred. Capital expenditures have to be spread across multiple years through depreciation or amortization because they create a lasting asset. The IRS draws the line clearly: the cost of acquiring, producing, or improving tangible property must be capitalized rather than immediately expensed.2eCFR. 26 CFR 1.263(a)-1 – Capital Expenditures; In General
Most core selling costs — ad campaigns, commissions, travel — are clearly consumed in the current period, so the distinction rarely bites. The trouble shows up in gray areas. Does a major website redesign aimed at boosting online sales count as a current-year selling expense or a capital improvement? Does new CRM software get expensed or capitalized?
The IRS provides a de minimis safe harbor for smaller purchases. Businesses with audited financial statements can expense tangible property costing up to $5,000 per item. Businesses without audited statements can expense items up to $2,500. Above those thresholds, the IRS looks at whether the expenditure creates something new, makes a betterment to existing property, restores property to working condition, or adapts it to a different use. Any of those outcomes typically requires capitalization.3Internal Revenue Service. Tangible Property Final Regulations
Businesses that want to accelerate the deduction of larger capital purchases can use the Section 179 election, which allows expensing qualifying assets in the year they’re placed in service instead of depreciating them. For tax years beginning in 2025, the Section 179 limit is $1,250,000, reduced once total qualifying property exceeds $3,130,000.4Internal Revenue Service. Revenue Procedure 2024-40 These limits adjust annually for inflation.
Deducting Selling Expenses Under Section 162
Because selling costs are operating expenses rather than capital outlays, they’re deductible as ordinary business expenses under 26 U.S.C. § 162, which allows a deduction for “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The statute specifically lists reasonable compensation for services, travel, and rent among the deductible items.
Two words do a lot of the work: “ordinary” and “necessary.” An ordinary expense is common and accepted in your type of business. A necessary expense is helpful and appropriate for running it. A software company deducting trade show booth costs meets both tests easily. A bakery deducting yacht charter costs for “client entertainment” will have a harder time.
Reasonableness sits inside the same test. Courts have read the “ordinary and necessary” standard to include an implicit reasonableness cap. A commission structure that pays salespeople 90% of revenue might technically be a selling expense, but the IRS can challenge whether it’s reasonable.
The payoff of the operating expense classification is timing. Selling expenses reduce taxable income dollar-for-dollar in the year incurred. A $50,000 advertising campaign cuts this year’s taxable income by $50,000. A $50,000 piece of equipment, by contrast, might have to be depreciated over five or seven years, spreading the same deduction across multiple returns. That timing difference is the single most important reason to classify a cost correctly in the first place.
