A business expense is an ordinary and necessary cost incurred to carry on a trade or business — deductible from gross income on the business's tax return, reducing taxable income dollar-for-dollar.
Under IRS rules (IRC Section 162), a business expense must be both 'ordinary' (common and accepted in the industry) and 'necessary' (appropriate and helpful for the business) to be deductible. The distinction matters because not all costs a business pays are deductible — personal expenses, capital expenditures (which must be depreciated), and fines/penalties are non-deductible. Common deductible business expenses include: rent, utilities, payroll and payroll taxes, insurance premiums, advertising and marketing, professional fees (legal, accounting), office supplies, business meals (generally 50% deductible), business travel, vehicle use (actual expenses or standard mileage rate), home office (if qualifying), bank fees, and subscriptions to trade publications or software. For lenders, business expenses visible on Schedule C or the corporate tax return directly affect net income — the figure used for loan qualification. High legitimate deductions reduce taxable income but also reduce apparent income for lending purposes. This creates a common tension: aggressive tax minimization (maximizing deductions) can hurt borrowing capacity. Understanding this trade-off before applying for financing is a strategic advantage.
A business expense is deducted in full in the year it's incurred. A capital expenditure (equipment purchase, building improvement) creates an asset that must be depreciated over its useful life — or immediately expensed via Section 179 or bonus depreciation. The IRS tests whether the cost extends the useful life of an existing asset or creates a new asset (capital) versus maintaining current operations (expense).
Generally no — the Tax Cuts and Jobs Act reduced the business meal deduction to 50% for most meals where business is discussed with a client or employee. The temporary 100% deduction for restaurant meals (2021-2022) has expired. Employee meals provided for the employer's convenience on-premises are 50% deductible (down from 100% pre-TCJA).
Deductions reduce net income on your tax return, which is the figure lenders use. If your Schedule C shows $200,000 gross income and $150,000 in deductions, lenders see $50,000 in net income — not $200,000. Lenders add back non-cash deductions (depreciation, amortization) but not most cash expenses. Balancing tax efficiency with documented qualifying income is a strategic planning decision.
