35 essential business expense categories for businesses of all sizes

Business expenses are the ordinary and necessary costs required to run a business. Any money spent in the name of doing business can be categorized as a business expense.

Every company incurs expenses in the course of doing business. Common examples of business expenses include the cost of goods and services, everyday operating expenses like payroll and rent, and countless others.

Organizing all your expenses into business expense categories ensures you know exactly how your business spends money. This makes it easier to plan budgets, control costs, and claim all your eligible business tax deductions on your income tax returns.

In this guide, Ramp explains what qualifies as a deductible business expense, breaks down how to categorize business expenses, and lists 35 common expense categories for businesses of any size, in addition to sharing some helpful tips to automate expense categorization.

What Is a Business Expense?

Because business expenses are tax-deductible, it’s important to understand exactly how the Internal Revenue Service, or IRS, defines them. According to the IRS, business expenses are ordinary and necessary costs incurred to run a business. Here’s what that means:

1. Ordinary: Common expenses for businesses in an industry.
2. Necessary: Expenses needed to operate a business, even if they aren’t indispensable.

‍Business expenses are sometimes called deductions because they are subtracted from revenue to determine taxable income. As such, they are recorded on a business income statement.

How Are Business Expenses Categorized?

The three main types of expenses are direct costs, indirect costs, and depreciation expenses. These can be further grouped into various expense categories, including payroll, employee benefits, general and administrative (G&A) expenses, marketing and advertising, research and development, and payments for professional services.

The key is to categorize expenses in a way that reflects a business’s structure—that is, by department and spend management needs. For example, expenses can be classified by type, like “G&A” and “Research and Development,” and then sorted by department, like “Marketing” and “Engineering.”

Small business owners often struggle with expense categorization, but there’s no need to overcomplicate the process. Keep expense categories general and limit the number of general ledger accounts. Use custom fields to capture the who, what, where, and why of each transaction to easily sort or reclassify them as needed.

For example, for internal purposes, it’s only necessary to know that an employee made a meal purchase. But to deduct the expense as a business meal come tax time, it’s key to know if the employee ate alone, with a team, or with a client, and what was discussed.

How to Make Sure Expense Categories Are Correct

Once categories that align with internal finance needs and IRS compliance have been determined, enforcing categorization comes next. Manually processing expenses has proven unreliable and time-consuming. Here’s how to ensure expenses are consistently and correctly categorized.

Expense management software can help automate expense mapping and categorization. Software that integrates with modern business expense cards adds another layer of control by providing customizable rules for every business expense.

Custom reporting workflows guarantee consistent documentation by prompting employees throughout the transaction process. Employees are immediately prompted via SMS or email to submit documentation for every transaction.

‍Once documentation is submitted, automated receipt matching ties it to the corresponding expense and prompts the employee to complete a memo. The expense management software then uses automation and AI to categorize the expenses and sync the information with bookkeeping or accounting software.
