What Is an Expense?
An expense is any cost a business incurs to earn revenue. In accounting, expenses reduce a company’s profit and are reported on the income statement. They include cash payments (rent, utilities, wages) and noncash costs (depreciation, amortization). Businesses manage and report expenses to track profitability, make decisions, and determine taxable income.
Key Takeaways
– Expenses are costs a firm incurs to produce revenue and operate day‑to‑day.
– Accountants record expenses under cash or accrual accounting; accrual matching is the norm for financial reporting.
– Expenses are typically split into operating (core business activities) and nonoperating (incidental activities).
– Capital expenditures (CapEx) are treated differently: they’re capitalized and depreciated or amortized over time.
– For tax deductions, an expense generally must be “ordinary and necessary” under IRS rules; some costs (e.g., fines, most lobbying) are nondeductible.

Understanding Expenses
– Definition: Costs incurred in the process of generating revenue.
– Role: Deducted from revenues to determine net income (Net income = Revenue − Expenses).
– Recording timing:
– Cash‑basis accounting: record expense when cash is paid.
– Accrual accounting: record expense when the obligation is incurred (matches expense to related revenue period).
How Expenses Are Recorded (Practical Steps)
1. Choose an accounting method
– Cash basis is simpler; accrual is required for many larger businesses and gives a more accurate matching of revenue and expense.
2. Set up a Chart of Accounts
– Create account categories: e.g., Rent Expense, Wages Expense, Utilities, Cost of Goods Sold (COGS), Interest Expense, Depreciation.
3. Capture documentation
– Keep invoices, receipts, payroll records, contracts. Scan/store digitally with date, vendor, purpose.
4. Record journal entries (examples)
– Cash basis (paying a utility bill): Debit Utility Expense, Credit Cash when paid.
– Accrual basis (utility incurred but unpaid): Debit Utility Expense, Credit Accounts Payable when incurred; later debit Accounts Payable, credit Cash when paid.
5. Reconcile monthly
– Reconcile bank statements, supplier statements, and payroll to the ledger to catch errors.
6. Report on financial statements
– Present operating vs nonoperating expenses separately on the income statement to show core operating performance.
Types of Business Expenses
– Operating expenses: costs directly related to the company’s main activities.
Examples: COGS, direct labor, materials, rent for production or retail space, utilities, office supplies, marketing, administrative salaries.
– Nonoperating expenses: costs not tied to core operations.
Examples: interest expense, losses on sale of assets, restructuring costs, certain legal settlements (unless tied to operations).
– Capital expenses (CapEx): funds used to acquire, improve, or extend the life of long‑term assets (buildings, machinery, computers). Treated as assets on the balance sheet and expensed over time via depreciation or amortization.
Fixed vs Variable Expenses
– Fixed expenses: don’t change with short‑term production levels (e.g., monthly rent, salaried wages).
– Variable expenses: change with production/sales volume (e.g., raw materials, hourly labor, shipping costs).
Classifying expenses by behavior helps budgeting and break‑even analysis.
Special Considerations
– Noncash expenses: Depreciation and amortization reduce accounting profit but don’t involve cash outflow in the period recorded. They reflect allocation of a capitalized cost over multiple periods.
– Capitalization rules: Under IRS tangible property regulations, many asset purchases must be capitalized and depreciated rather than deducted in full immediately. There are exceptions (e.g., Section 179 expensing, bonus depreciation) — consult tax guidance for eligibility.
– Deductibility standard: The IRS generally allows deduction of business expenses that are “ordinary and necessary” (ordinary = common in the trade; necessary = helpful and appropriate). Personal expenses are not deductible. Certain items are explicitly nondeductible (e.g., most fines, penalties, and many lobbying costs). (See IRS Pub. 334 and related guidance.)
Not All Expenses Can Be Deducted
– Examples of commonly limited or nondeductible items:
– Personal expenses (not business related)
– Fines and penalties paid to governments
– Certain political and lobbying expenditures
– Some entertainment expenses (rules changed — partial deductions may be limited)
Always document business purpose and retain substantiation. For items with gray areas, consult a tax advisor.
Is a Salary Considered an Expense?
Yes. Employee wages and salaries are operating expenses and are recorded on the income statement. Payroll also generates related expenses such as employer payroll taxes, benefits, and retirement plan contributions.
What Are Examples of Expenses?
Common examples:
– Rent and utilities
– Employee wages and benefits
– Cost of goods sold (materials, factory labor)
– Marketing and advertising
– Office supplies and software subscriptions
– Insurance
– Maintenance and repairs
– Depreciation and amortization
– Interest expense (typically nonoperating)
– Professional services (legal, accounting)
Practical Steps to Manage and Optimize Expenses
1. Implement consistent bookkeeping and documentation practices
– Keep digital copies of receipts, vendor contracts, and invoices. Use accounting software and tag expenses by category.
2. Separate personal and business finances
– Use separate bank accounts and cards to avoid commingling and simplify audits.
3. Classify and review expenses regularly
– Monthly review of expense reports and G/L to identify anomalies or misclassifications.
4. Analyze fixed vs variable costs
– Evaluate adjustable cost structure; convert fixed to variable where practical (e.g., outsourcing) to improve flexibility.
5. Benchmark and monitor ratios
– Track gross margin, operating margin, and operating expense ratios vs industry peers.
6. Control procurement and approval processes
– Set thresholds for approvals, use purchase orders, and negotiate supplier contracts.
7. Use tax‑efficient strategies for CapEx
– Consider Section 179 or bonus depreciation where available; plan CapEx timing with tax and cash flow in mind.
8. Engage tax and accounting professionals
– For complex capitalization, depreciation schedules, or tax‑deductibility questions, consult a CPA or tax attorney.
Checklist for Determining Whether an Expense Is Tax‑Deductible
– Was the expense incurred to produce or sell income?
– Is the expense ordinary (customary in your industry)?
– Is it necessary (appropriate and helpful for the business)?
– Is it properly documented (receipts, invoices, time records)?
– Is the expense personal or partly personal? If partly personal, determine the business portion only.
– Are there specific IRS limitations or disallowances for this type of expense?
Examples: Recording and Treatment
– Example 1 — Office rent (fixed operating expense): Monthly entry (accrual): Debit Rent Expense, Credit Accounts Payable (or Cash when paid). Deductible in the year paid/incurred.
– Example 2 — Buying a $50,000 machine (CapEx): Capitalize as Equipment (asset) then record depreciation each period (noncash expense) per IRS lives, unless eligible for immediate expensing under tax provisions.
– Example 3 — Sales commissions (variable operating expense): Expense when earned under accrual accounting; directly affects gross or operating margin.
The Bottom Line
Expenses are the costs required to run a business and are essential to measuring profitability. Proper classification (operating vs nonoperating, capital vs expense), consistent recording (cash vs accrual), careful documentation, and knowledge of tax rules (ordinary and necessary test; capitalization rules) are critical to accurate financial reporting and minimizing tax liability. When in doubt about deductibility or capitalization, consult an accounting or tax professional.
