Business Expense Categories: Schedule C Categories List 2026

Quick answer: The best business expense categories for a US sole proprietor or single-member LLC are the Schedule C categories: advertising, car and truck, commissions, contract labor, depreciation, insurance, interest, legal and professional, office, rent, repairs, supplies, taxes and licenses, travel, meals, utilities, wages, other expenses and home office. Matching your books to them makes filing simple.

Every expense you record needs a home. Choose business expense categories well and your bookkeeping answers three questions at once: where your money goes, what you can deduct, and which line of your tax return each cost belongs on. Choose them badly and you will spend a weekend every April re-sorting transactions. This guide gives you the full Schedule C categories list, examples for each, the 2026 rules that trip people up and a worked example. If you bill clients for costs, our invoice generator lets you itemize them clearly.

Important: This is general information, not tax advice. Deduction rules have limits and exceptions, so confirm specific items with a tax professional.

Why use Schedule C categories for your books

Schedule C is the form sole proprietors and single-member LLCs use to report business profit. Its Part II lists the expense lines the IRS expects. If your chart of accounts mirrors those lines, your profit and loss statement converts directly into the tax form with no reclassification. Partnerships and corporations use different forms, but the same groupings still make sense for management reporting.

The test for any deduction is that the cost is ordinary and necessary for your business. The category does not make something deductible, it only records where a valid deduction goes.

The complete Schedule C categories list

This table follows the line numbers in the IRS instructions for Schedule C for tax year 2025, the latest final version at the time of writing:

Line	Category	Typical examples
8	Advertising	Online ads, website promotion, printed flyers, sponsorships
9	Car and truck expenses	Standard mileage or actual costs, plus business parking and tolls
10	Commissions and fees	Sales commissions, marketplace and platform fees
11	Contract labor	Freelancers and subcontractors who are not employees
12	Depletion	Natural resources such as timber or minerals
13	Depreciation and section 179	Computers, equipment, vehicles (with Form 4562)
14	Employee benefit programs	Health plans and group-term life for employees
15	Insurance (other than health)	Liability, professional indemnity, business property
16a / 16b	Interest	Mortgage interest on business property; loan and card interest
17	Legal and professional services	Accountant, attorney and tax preparation for the business
18	Office expense	Office supplies, postage
19	Pension and profit-sharing plans	Employer contributions for employees
20a / 20b	Rent or lease	Vehicles and equipment; office or other property
21	Repairs and maintenance	Incidental repairs that do not improve or extend an asset
22	Supplies	Materials used up in your work
23	Taxes and licenses	Business licenses, employer payroll taxes, state business taxes
24a	Travel	Airfare, lodging and transport on overnight business trips
24b	Deductible meals	Business meals, generally 50% deductible
25	Utilities	Business share of phone, internet, power
26	Wages	Employee pay, less certain credits
27a	Energy efficient commercial buildings	Section 179D deduction (Form 7205)
27b	Other expenses (from Part V)	Software, bank fees, dues, education, gifts
30	Business use of home	Form 8829 or simplified method

The 2025 instructions note two layout changes: the energy efficient buildings deduction moved to line 27a, and other expenses from Part V now go on line 27b. Cost of goods sold is separate, in Part III, for businesses that sell products. See our guide to cost of goods sold.

Categories that need extra care

Car and truck expenses

You choose the standard mileage rate or actual costs. For 2026, the IRS business rate is 72.5 cents a mile for January 1 to June 30 and 76 cents a mile from July 1 to December 31, after a midyear increase linked to fuel prices. Our sibling posts on the IRS mileage rate for 2026 and standard mileage vs actual expenses explain which method suits you. A mileage log is essential either way.

Meals and travel

The Schedule C instructions state that the business meals deduction is 50%, or 80% for people subject to Department of Transportation hours-of-service limits. Travel (line 24a) covers transport and lodging when you are away from home overnight. Keep meal receipts with a note of who attended and why.

Assets vs expenses

Equipment that lasts more than a year is generally capitalized and depreciated on line 13, or expensed under section 179 or bonus depreciation. The 2025 instructions list a section 179 limit of $2.5 million and allow 100% bonus depreciation for certain property placed in service after January 19, 2025. Small items can often be expensed under the de minimis safe harbor election. Our guide to section 179 vs bonus depreciation goes deeper.

Home office

Line 30 uses Form 8829 or the simplified method of $5 per square foot up to 300 square feet. See our home office deduction guide.

Contract labor

Line 11 is for non-employees. If you paid one person $2,000 or more in 2026 by cash, check or bank transfer, you may need to file a 1099-NEC. Our sibling guide on how to file 1099-NEC walks through it.

Useful sub-categories under other expenses

Line 27b is a catch-all, so most businesses keep sub-accounts and list them in Part V:

• Software and subscriptions (design tools, accounting, cloud storage)
• Bank and payment processing fees, unless you treat them as commissions and fees
• Professional dues and memberships
• Education and training that maintains or improves skills for your current business
• Business gifts, subject to the long-standing $25 per recipient per year limit
• Small tools and equipment expensed under the de minimis election

Expense categories by type of business

The same Schedule C lines apply to everyone, but which ones matter most depends on what you do. This table shows where typical costs tend to concentrate:

Business type	Largest categories	Watch out for
Freelance designer or developer	Other expenses (software), depreciation (computers), home office	Splitting phone and internet between personal and business use
Consultant	Travel, meals, car and truck, professional fees	Applying the 50% meals limit and keeping trip purposes
Cleaning or lawn care	Supplies, car and truck, contract labor, insurance	Equipment that should be depreciated rather than expensed
Trades and construction	Supplies or cost of goods sold, car and truck, depreciation, contract labor	Materials billed to clients versus materials used up in overhead
Online product seller	Cost of goods sold, commissions and fees, advertising	Putting inventory in supplies instead of Part III
Agency with staff	Wages, employee benefits, rent, taxes and licenses	Separating contractors on line 11 from employees on line 26

What you cannot deduct in any category

Some costs look like business expenses but are not deductible, or are limited. Keep them out of your expense categories, or record them in a separate non-deductible account so your books still reconcile:

• Federal income tax and self-employment tax. The Schedule C instructions say these do not belong on line 23. Half of self-employment tax is deducted on Form 1040 instead.
• Owner draws. Money you transfer to yourself is not an expense for a sole proprietor or single-member LLC.
• Personal share of mixed costs. Only the business portion of a phone, car or home is deductible.
• The base rate of the first home phone line. The Schedule C instructions specifically exclude it, although extra business calls and a separate business line can be deducted.
• Fines and penalties paid to a government for breaking the law.
• Loan principal. Repaying a business loan is not an expense; only the interest is.
• Capital improvements, which are depreciated over time rather than deducted as repairs.

Getting these right in your bookkeeping means your profit figure is closer to your taxable profit, which makes estimated tax payments more accurate during the year.

How to set up and use your expense categories

1. Start from the Schedule C lines above and delete any you will never use, such as depletion.
2. Add three to six sub-accounts under other expenses for your biggest recurring costs.
3. Write a one-line rule for each category so you code similar costs the same way every time.
4. Use a separate business account and card so every transaction is business by default.
5. Categorize weekly rather than once a year. Our guide on how to track business expenses suggests a routine.
6. Attach receipts and note the purpose for meals, travel and mixed-use items.
7. Bill reimbursable costs to clients on a separate invoice line. See reimbursable expenses on invoices.
8. Review your profit and loss monthly to catch miscoded items early.

A good rule of thumb: if you cannot decide between two categories in a few seconds, write down which one you chose and why, then use the same answer every time. Consistency matters more than perfection, because the IRS and your accountant care that similar costs are treated the same way from year to year. If you change a rule, note the date so year-over-year comparisons still make sense.

Worked example: one year of expenses by category

Jordan is a freelance consultant with $80,000 of 2026 revenue. Here is how a year of costs lands on Schedule C:

Line	Category	Calculation	Deduction
8	Advertising	Online ads	$1,200.00
9	Car and truck	1,900 miles x $0.725 + 2,100 miles x $0.76	$2,973.50
11	Contract labor	Freelance researcher	$3,500.00
15	Insurance	Professional liability	$1,100.00
17	Legal and professional	Accountant	$900.00
18	Office expense	Supplies and postage	$650.00
22	Supplies	Workshop materials	$780.00
24a	Travel	Two client trips	$1,400.00
24b	Meals	$1,000 spent x 50%	$500.00
25	Utilities	Business share of phone and internet	$600.00
27b	Other expenses	Software subscriptions	$1,850.00
Total expenses			$15,453.50

The mileage line splits because the rate changed on July 1: 1,900 x 0.725 = $1,377.50 and 2,100 x 0.76 = $1,596.00. Jordan's net profit is $80,000 - $15,453.50 = $64,546.50, which flows to Schedule SE for self-employment tax and to Form 1040. Because the paid contractor received $3,500, Jordan also checks whether a 1099-NEC is needed.

Common categorization mistakes

• Deducting 100% of meals instead of the 50% limit.
• Expensing a large asset as supplies without a section 179, bonus or de minimis basis.
• Putting owner draws in expenses. Money you take out is not a deduction.
• Claiming mileage and gas together. The standard rate already covers fuel.
• Dumping everything in other expenses, which hides trends and invites questions.
• Mixing personal costs through the business account without recording them as draws.

For a wider list of what you can claim, see our guide to self-employed tax deductions and remember that every category should roll up into a monthly profit and loss you actually read.
