Selling expenses are the costs a business incurs to market, sell, and deliver its products or services: sales commissions, advertising, sales salaries, outbound shipping, CRM subscriptions, trade show fees, and similar items. They sit on the income statement as operating expenses, below gross profit, so they reduce operating income directly. For tax purposes, most selling expenses are deductible as ordinary and necessary business expenses, though meals, entertainment, and long-term contract commissions follow special rules.
What Counts as a Selling Expense
Selling expenses fall into two groups, and the split matters both for budgeting and for reading the numbers later.
Direct Selling Costs
Direct selling costs can be tied to a specific sale, customer, or order. They rise and fall with sales volume.
- Sales commissions. A 5% commission on a $100,000 sale creates a $5,000 selling expense for that transaction.
- Outbound shipping to get finished goods to the customer. Whether the seller or the buyer bears the cost depends on shipping terms; under FOB Destination the seller pays and records the freight as a selling expense.
- Sales travel for a representative pursuing a specific deal: airfare, hotels, meals, rental cars.
- Transaction fees. Credit card processing charges, payment platform fees, and marketplace referral fees tied to completed sales.
The test is traceability. If you can point to the invoice, order, or customer that triggered the cost, it belongs here.
Indirect Selling Costs
Indirect selling costs support the sales function broadly but can’t be linked to a single transaction. Most are fixed or semi-fixed and show up whether or not any particular deal closes.
- Advertising and marketing: online campaigns, social media spending, print placements, content production, brand sponsorships.
- Base salaries for sales managers, account executives, and marketing staff.
- Rent, utilities, and insurance for a dedicated sales office or showroom.
- CRM platforms, sales analytics software, email marketing tools.
- Depreciation on company vehicles assigned to sales or equipment used in product demos.
- Trade shows and events: booth rentals, sponsorships, promotional materials, and related travel.
Managing the two categories calls for different levers. Direct costs improve through per-unit efficiency, such as renegotiating shipping rates or restructuring commissions. Indirect costs improve through budgeting discipline and periodically asking whether the infrastructure still matches the revenue it produces.
Selling Expenses vs. COGS and G&A
Nearly every operating cost lands in one of three buckets: cost of goods sold, selling expenses, or general and administrative. The lines between them matter more than most people realize, because misclassification shifts gross profit, operating income, or both.
Cost of goods sold covers what it takes to create the product: raw materials, production labor, factory overhead, manufacturing equipment depreciation. The dividing line is the factory door. A factory worker’s wages are COGS. The sales manager’s salary is a selling expense. Inbound freight on raw materials is COGS; outbound freight to a customer is a selling expense. Booking advertising as COGS understates gross margin and makes the product look more expensive to produce than it is.
General and administrative expenses cover the cost of running the business itself: executive pay, legal fees, accounting, HR, corporate office space. The question to ask is whether the cost exists to generate sales or to keep the organization functioning regardless of sales activity. The CFO’s salary is G&A. The VP of Sales’ salary is a selling expense. The function performed by a person or space determines the classification, not the physical address.
How to Record Selling Expenses
Selling expenses follow accrual accounting. You record the expense in the same period as the revenue it helped generate, not when the check goes out. A commission earned on a deal closed in March is a March expense even if it isn’t paid until April. Matching keeps the income statement from bouncing around based on payment timing rather than actual performance.
Allocating Shared Costs
When a single cost serves both sales and another department, you need a rational basis to split it. A shared headquarters building requires dividing rent between selling expenses and G&A. Common methods are square footage occupied, headcount, or actual usage hours for shared technology. The method doesn’t need to be perfect, but it does need to be reasonable, documented, and applied consistently. Switching allocation methods quarter to quarter to flatter a specific metric is the kind of thing auditors notice immediately.
When Sales Commissions Must Be Capitalized
Under ASC 340-40, sales commissions that are incremental to obtaining a contract, meaning the company wouldn’t have paid them without that specific deal, must be capitalized as an asset if the company expects to recover the cost. The capitalized amount is then amortized over the period the company expects to benefit from the contract. On a three-year software subscription, the commission paid at signing gets spread across all three years rather than hitting the income statement in year one.
There is a practical expedient. If the amortization period would be one year or less, the company can expense the commission immediately. This is an accounting policy election, so once adopted it must be applied consistently to all similar contracts. Companies with short sales cycles or month-to-month contracts typically use the expedient. Companies selling multi-year enterprise contracts don’t have that option.
Tax Deduction Rules for Selling Expenses
Selling expenses are generally deductible as ordinary and necessary business expenses under federal tax law. To qualify, the cost must be common in your industry (ordinary) and helpful or appropriate for your business (necessary); it doesn’t need to be indispensable.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Sales commissions, advertising, sales salaries, and office rent for sales locations all clear that bar easily. The IRS has specifically noted that advertising expenses, even small ones like a half-page ad in a community event program, are deductible as long as the purpose is encouraging people to buy your products.2Internal Revenue Service. Publication 535 – Business Expenses
Meals and Entertainment
Not every selling expense is fully deductible. Business meals with a legitimate business purpose, such as taking a client to lunch to discuss a proposal, are only 50% deductible.3Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses The same 50% cap applies to meals during business travel. Entertainment expenses like sporting events, golf outings, and concert tickets are fully nondeductible, no matter how strong the business connection. Starting in 2026, meals furnished on the employer’s premises for the employer’s convenience, such as cafeteria meals or food for employees working late, also became fully nondeductible. Company-wide social events like holiday parties remain 100% deductible.
Substantiation matters. For meals you want to deduct, keep records of who attended, the business purpose, and the amount. Vague entries like “client dinner” on an expense report won’t survive an audit.
Reporting Commissions to Outside Sales Agents
When a business pays commissions to independent contractors rather than employees, there is a reporting obligation. For tax year 2026, any nonemployee compensation totaling $2,000 or more must be reported on Form 1099-NEC.4Internal Revenue Service. 2026 Publication 1099 – General Instructions for Certain Information Returns This threshold increased from $600 for tax years beginning after 2025 and will adjust for inflation starting in 2027. The IRS matches 1099 filings against contractor returns, so missed filings tend to surface.
Judging Whether Selling Expenses Are Reasonable
The standard measure is the selling expense ratio: total selling expenses divided by net revenue, expressed as a percentage. A company spending $2 million on selling costs to generate $10 million in revenue has a 20% ratio. Tracked over time, this reveals whether the sales operation is becoming more or less efficient as the business grows.
What counts as a good ratio varies enormously by industry. Asset-light businesses that compete on brand recognition, such as apparel companies and consumer software, routinely spend 30% to 50% of revenue on selling and administrative costs. Capital-intensive industries like manufacturing, agriculture, and construction typically run below 10%. The ratio is most useful when compared against direct competitors or the company’s own historical trend, not against unrelated industries.
A rising ratio isn’t automatically a problem. A company entering a new market or launching a product line will spike its selling expenses before the corresponding revenue arrives. The concern is when the ratio climbs over several periods with no strategic explanation, which usually points to pricing, channel mix, or team productivity issues that need attention.
