What are business expenses?
Business expenses are the costs a company incurs to operate, manage, and grow the business. These expenses range from employee salaries and office rent to software subscriptions, marketing campaigns, and equipment purchases.
How to categorize business expenses
To categorize business expenses, businesses should group each expense based on its purpose, frequency, and financial impact. Typically, expenses are categorized into operating expenses (day-to-day costs), capital expenditures (long-term investments), and tax-deductible or non-deductible expenses for accounting and tax purposes.
1. Operating expenses (OpEX)
These are everyday costs that help day-to-day in running a business, like office rent, utilities, payroll, etc.
2. Capital expenditures (CapEx)
These are long-term investments that provide value over multiple years, like office property, machinery, technologies, etc.
3. Tax-deductible vs non-deductible expenses
Not every business expense is meant to end up in a tax audit. The IRS defines deductible business expenses as those that are “ordinary and necessary” for operating your trade or business, where “ordinary” means common in your industry and “necessary” means helpful and appropriate for business operations. Businesses can refer to IRS Publication 535, Business Expenses, for detailed guidance on deductible expenses and classifications.
- Deductible expenses: These expenses are directly related to business operations and are considered to be used to build the business, such as salaries, software tool subscription, etc.
- Non-deductible expenses: These expenses are not taxed and cannot be written off for tax purposes, such as government fines, donations, penalties, etc.
35 standard business expense categories for small businesses and startups
There are 35 categories for small business expenses that you need to know beforehand to help optimize your cash flow and accounts accordingly.
Facilities, workspace & overhead
1. Rent or lease payments
These costs are associated with businesses that have physical office spaces, coworking spaces or memberships, warehouses, storage units, or any leased commercial property to support their business operations. This is usually a monthly or quarterly recurring expense with a low audit risk. For example, if your office is rented, you pay for a coworking space monthly/ annual, warehouse leases, etc.
2. Utilities
Expenses that support you in keeping the commercial workspace you have rented operational. This is typically a monthly recurring expense with a low audit risk and includes electricity bills, water bills, internet charges, phone bills, and waste management costs. For example, a tech startup paying for high-speed internet and electricity for its office or a restaurant managing monthly gas and utility bills would record these costs here.
3. Office supplies and consumables
This business expense category includes costs or expenses incurred for stationery or money spent on regular items such as paper, pens, printer ink, notebooks, pantry and kitchen supplies, etc. These are usually weekly or monthly recurring expenses with a low audit risk.

5. Real estate costs and property taxes
Government taxes commercial property owned by businesses through commercial property taxes, state property taxes, local municipal property taxes, etc. These are usually annual or semi-annual expenses with a low audit risk.

8. Employee benefits
If your employees get any business-sponsored benefits such as health insurance, retirement contributions, life insurance, or any wellness program, this is where you need to categorize them.

Any contribution that your company makes to employer-paid taxes associated with employee compensation. For example, FICA taxes, FUTA taxes, state unemployment taxes, etc. These are usually monthly or annual recurring expenses with a low audit risk.

5 business expense categories for modern businesses and startups
The standard IRS business expense categories were designed for expenses that the company incurred decades ago. After the wide digitalization and a drastic change in how businesses work today, many new categories have been added to maintain clean corporate books and precise unit economics.
1. Remote work allowances and reimbursements
Modern businesses allocate monthly reimbursements for employees working remotely. These are monthly expenses with a medium risk of audit. This includes employee home internet installations and bills. For example, when a company reimburses for internet expenses or when an employee spends on an office setup like ergonomic chairs, coworking memberships, etc.
From a tax perspective, these costs are generally treated as employee business expenses or operational reimbursements when supported by accountable reimbursement plans.
2. Data security and cybersecurity compliance
With the growing risk of data being compromised, given the larger volumes of customer and financial data online, you are bound to spend on data security alternatives such as outlays for SOC2 audits, penetration-testing tools, vulnerability scanners, and enterprise encryption software.
Most businesses currently classify cybersecurity expenses under software and SaaS subscriptions, IT infrastructure, or compliance-related operational costs. In many cases, these expenses are tax-deductible because they are considered necessary to protect business operations and maintain regulatory compliance.
3. Employee wellness and mental health benefits
As businesses today promote healthy work environments for employees to work, they spend on subscriptions to wellness apps, mental health platforms, and fitness stipends designed to boost team retention.
These expenses are often categorized under employee benefits or professional development costs, depending on how the company structures the program. Many wellness-related expenses may qualify as deductible business expenses if they are tied to employee welfare and company-sponsored benefit programs.
4. Global contractor compliances and localizations
In the past few years, remote hiring has increased significantly. Onboarding and compliance fees paid to platforms like Deel or Remote to legally hire, pay, and manage international team members.
Most businesses categorize these expenses under contractor fees, payroll operations, or compliance and legal services. These costs are generally treated as deductible operational expenses because they directly support workforce management and international business operations.
5. AI Tools and API usage
Dedicated expense tracking software for OpenAI tokens, Midjourney subscriptions, or LLM infrastructure costs to monitor your automated workflows. Modern businesses are increasingly spending on AI-powered tools and automated workflows to improve productivity, customer support, analytics, and content generation.
The IRS hasn't yet issued specific guidance on AI tool expenses; most businesses currently classify them under Software and SaaS subscriptions or R&D costs, depending on how they're used.
Best practices to categorize business expenses
Accurate business expense categories help maintain clean records, build expense reports, assist with budgeting, tax reporting, cash flow visibility, and financial decision-making. Some of the best practices that you can follow to categorize your business expenses neatly are:
1. Build a consistent chart of accounts (CoA)
Create standard categories that fit right with your business and accounting model. Maintain this consistently across your accounting system. Make sure the changes are minimal, as that may result in errors and make financial analysis difficult.
2. Enforce digital receipt management
Instruct your teams to store invoices, receipts, and payment records digitally rather than on paper. The record should clearly mention the vendor name, transaction date, amount paid, and the business purpose.
3. Review your expenses at regular intervals
Review and keep a track of your business expense categories regularly instead of waiting for the month-end. A weekly check to ensure error-free accounting and transactions can improve real-time cash flow tracking.
4. Create and document expense policy
Build a clear expense policy template that outlines how employees should report, categorize, approve, and reimburse business expenses. Your expense policy should define approved expense categories, spending limits, receipt submission requirements, reimbursement timelines, and approval workflows to maintain cleaner financial records and reduce policy violations.
