Running a business comes with plenty of expenses. The question many business owners have is: Which of those expenses can I actually deduct?
Understanding small business tax deductions can help you make better financial decisions, maintain stronger records, and avoid waiting until tax season to figure out where your money went.
The IRS generally requires a deductible business expense to be both ordinary and necessary. In simple terms, the expense should be common or accepted in your type of business and helpful or appropriate for operating that business.
That does not mean every expense you pay from your business bank account automatically becomes deductible. Personal expenses generally remain personal, and certain business expenses have special limitations.
Here are 25 common small business tax deductions and expense categories business owners should understand.
1. Advertising and Marketing
Expenses used to promote your business may generally be deductible.
Examples can include social media advertising, Google Ads, printed flyers, business cards, promotional materials, website advertising, sponsorships that qualify as advertising, and other marketing costs.
If you are spending money specifically to attract customers or promote your services, make sure those expenses are properly categorized in your accounting records.
2. Office Supplies
Ordinary supplies used in your business may be deductible.
This could include paper, ink, pens, folders, printer supplies, postage supplies, notebooks, and other materials used in your day-to-day business operations.
Small purchases are easy to overlook, so keeping them organized throughout the year matters.
3. Software and Business Subscriptions
Many businesses now operate using monthly software subscriptions.
Examples may include bookkeeping software, payroll software, scheduling platforms, project-management tools, cloud storage, graphic-design software, client portals, cybersecurity services, and other applications used for business.
Those recurring $15, $30, or $50 monthly charges can add up quickly over an entire year.
4. Business Phone Expenses
If you use a phone for business, the business portion of that expense may be deductible.
If the same phone is used for both business and personal purposes, you generally need to determine the portion that relates to business use.
Maintaining a separate business phone line can make this easier to track.
5. Business Internet Expenses
Internet service used to operate your business may also qualify as a business expense.
If your home internet is used for both personal and business purposes, you may need to allocate the expense between the two uses rather than deducting the entire bill.
6. Office or Commercial Rent
Rent paid for an office, storefront, studio, warehouse, or other space used in your business may generally be deductible.
The rules are different when you own the property or when the property is also your personal residence, so those situations require additional analysis.
7. Utilities
Utilities associated with business property may be deductible.
Depending on the business, this could include electricity, water, gas, trash service, and other utility expenses.
Home-based businesses should pay particular attention to the separate rules for the business use of a home.
8. Business Insurance
Certain insurance premiums related to your business may be deductible.
Examples can include general liability insurance, professional liability coverage, business property insurance, workers' compensation coverage, and other policies directly related to operating the business.
Personal insurance should not simply be recorded as a business expense because it was paid from a business account.
9. Accounting and Bookkeeping Fees
Professional accounting and bookkeeping services used for your business may generally be deductible.
That can include monthly bookkeeping, business tax preparation, payroll support, financial reporting, and certain advisory services related to the business.
Good accounting is not just a tax-time expense. Accurate financial records can help you make better decisions throughout the year.
10. Legal and Professional Fees
Fees paid to attorneys, consultants, and other professionals may be deductible when the services relate to your business.
The tax treatment can vary depending on what the professional was hired to do, particularly when the expense relates to acquiring property, forming a business, or another long-term asset.
11. Independent Contractors
Payments made to independent contractors for legitimate business services may generally be deductible.
Examples can include virtual assistants, freelance designers, consultants, photographers, subcontractors, and other nonemployee service providers.
Remember that certain contractor payments may also create Form 1099 reporting requirements.
12. Employee Wages
Wages paid to employees for services performed for your business may generally be deductible if the compensation is reasonable and meets the applicable tax rules.
Payroll should be properly documented and reported.
13. Payroll Taxes and Certain Employee Costs
Employer-paid payroll taxes and certain employee-related expenses can also be business expenses.
Businesses with employees should make sure payroll liabilities, payroll tax deposits, and year-end reporting are being handled correctly.
14. Bank and Merchant Processing Fees
Business bank fees and payment-processing costs are easy to forget.
Examples can include monthly bank service charges, credit-card processing fees, PayPal or Stripe fees, merchant account charges, and other fees incurred when customers pay your business.
15. Business Loan Interest
Interest paid on qualifying business debt may be deductible, subject to applicable limitations.
The key distinction is that the interest may be deductible. Repayment of the loan principal itself generally is not a business expense deduction.
16. Repairs and Maintenance
Ordinary repairs and maintenance performed to keep business property or equipment working may be deductible.
However, a major improvement that substantially increases the property's value or extends its useful life may need to be capitalized instead of deducted as a routine repair.
17. Business Licenses and Permits
Fees required to operate your business may qualify as deductible business expenses.
Examples can include local business licenses, professional licensing fees, permit costs, and certain registration fees.
18. Professional Education and Training
Education that maintains or improves skills needed in your existing business may potentially be deductible.
Examples can include professional training, continuing education, industry conferences, qualifying seminars, and certain educational materials.
Not every education expense qualifies, especially if it prepares you for an entirely new trade or profession.
19. Business Travel
Ordinary and necessary travel away from your tax home for business may qualify for a deduction.
Potential expenses can include airfare, lodging, transportation, baggage fees, business communications, and other qualifying travel costs.
The trip needs to have a legitimate business purpose, and documentation is important.
20. Business Meals
Qualifying business meals are generally 50% deductible, although exceptions can apply.
Typically, you or an employee must be present, the meal cannot be lavish or extravagant under the circumstances, and there should be a legitimate business connection.
Entertainment expenses are generally not deductible simply because business was discussed.
Always document who attended and the business purpose of the meal.
21. Business Vehicle Expenses
If you use your vehicle for business, you may be able to deduct the business portion using either the standard mileage method or, when eligible, the actual-expense method.
For 2026, the IRS business standard mileage rate is:
72.5 cents per business mile from January 1 through June 30, 2026
76 cents per business mile beginning July 1, 2026
Personal commuting is not the same as deductible business mileage.
Keep a contemporaneous mileage log that includes the date, destination, business purpose, and miles driven.
22. Business Parking and Tolls
Parking and toll expenses related to qualifying business travel may be deductible.
These expenses should still be separated from personal commuting costs.
Small expenses like parking can be easily forgotten if you wait until tax season to reconstruct them.
23. Home Office Expenses
Some self-employed business owners may qualify for the home office deduction.
Generally, the space must be used regularly and exclusively for business, subject to several exceptions and additional requirements.
The IRS provides both simplified and actual-expense methods for qualifying taxpayers.
A dining room table that is also regularly used for family meals generally does not satisfy the exclusive-use requirement simply because you occasionally work there.
24. Business Equipment and Furniture
Computers, office furniture, machinery, cameras, tools, and other equipment purchased for your business may provide tax deductions.
How and when you claim the deduction can depend on the type and cost of the asset and the depreciation rules that apply.
Some purchases may qualify for accelerated deductions, while others may be depreciated over multiple years.
25. Professional Memberships and Business Dues
Membership fees paid to qualifying professional and trade organizations related to your business may potentially be deductible.
However, dues paid to certain social, athletic, entertainment, or similar clubs generally do not receive the same treatment.
Make sure the organization has a legitimate connection to your business or profession.
Good Recordkeeping Is Just as Important as Knowing the Deduction
Finding a deduction is only one part of the process.
You should also be able to support the expense.
Maintain organized records such as receipts, invoices, bank statements, mileage logs, contracts, and documentation showing the business purpose of expenses when appropriate.
Do not rely on your memory in March or April to reconstruct an entire year of business activity.
A simple monthly bookkeeping routine can save you significant time and stress at tax time.
Not Every Business Gets the Same Deductions
Your available deductions depend on factors such as your industry, business structure, type of expense, how an asset is used, and your individual tax situation.
A deduction that makes sense for a consultant may look very different from the deductions available to a contractor, real estate professional, online retailer, restaurant owner, or creative professional.
That is why tax planning should happen throughout the year, not only when the tax return is being prepared.
