What are business expenses?

Business expenses refer to the costs you incur while operating your business day to day. They’re the same expenses you must carefully track throughout the year to deduct from your taxable income.

To be deductible, business expenses must fall within the categories of "ordinary or necessary" expenses. Generally, "ordinary expenses" are common and widely accepted in your industry, think business meals or mileage, whereas "necessary expenses" are deemed essential or helpful in your particular line of work or trade, like inventory, rent, and utilities.

Categories of business expenses

Business expenses are classified into several distinct categories. Each serves a unique purpose and allows you to gain better oversight over finances, optimize your business budgeting efforts, and make more informed decisions about resource allocation overall.

Fixed expenses

These expenses remain consistent month over month, regardless of the level of business activity. Examples include rent or lease payments for your office space, insurance premiums, membership fees, and employees' salaries.

Variable expenses

Unlike fixed expenses, variable expenses fluctuate with the level of business activity. They’re directly tied to the volume of goods produced or services completed. They can include costs for raw materials, production supplies, utilities, and sales commissions.

Periodic expenses

Periodic expenses occur at specific intervals, usually annually or quarterly. Examples include business license renewals, equipment maintenance contracts, professional certifications, and tax filing fees.

Interest expenses

If your business has borrowed money or has outstanding debt, interest expenses represent the cost of borrowing funds from lenders or financial institutions. These include interest payments on business loans, lines of credit, or credit card balances.

Depreciation expenses

Depreciation refers to the gradual loss of asset value over time due to obsolescence, wear and tear, or technological advancements. These expenses include costs related to the depreciation of buildings, equipment, vehicles, and other tangible assets.

Business expenses vs. personal expenses

You also need to draw a clear line between business and personal expenses. Personal expenses are only related to your life outside the company and aren't tax-deductible, while business expenses are incurred solely for business purposes.

Misclassifying personal expenses as business expenses can result in inaccurate tax reporting, leading to potential audits and IRS penalties.
