Updated 2026-10-18 · Not tax advice

Figures used: Line numbers and rules come from the 2025 Schedule C (Form 1040) and its instructions, the latest revision on IRS.gov on October 15, 2026. Mileage rates are from the IRS standard mileage rates page: 72.5 cents a mile for January to June 2026 and 76 cents for July to December 2026. Check the 2026 form when the IRS publishes it.

Schedule C (Form 1040) is where a freelancer, 1099 contractor or sole proprietor reports business income and expenses. Your net profit on line 31 feeds both your income tax and your self-employment tax, and it is the number your quarterly estimated taxes are built on. This list follows the IRS Instructions for Schedule C line by line.

Where does each expense go on Schedule C?

Line	Category	Common freelancer examples	Watch out
8	Advertising	Online ads, sponsored posts, flyers
9	Car and truck expenses	Business miles at the standard rate, plus parking and tolls	Commuting doesn’t count. Keep a mileage log
10	Commissions and fees	Marketplace and platform fees, referral commissions	Report platform income gross on line 1 (the 1099-K amount is before fees), then deduct the fees once here
11	Contract labor	Subcontractors, freelance editors or designers you hire	Employees go on line 26
12	Depletion	Rare for freelancers (natural resources, timber)
13	Depreciation and section 179	Computers, cameras, furniture that last more than a year	Usually needs Form 4562. Items you expense under the de minimis safe harbor ($2,500 or less each) go on line 27b instead
14	Employee benefit programs	Health plans or group-term life for employees	Not your own health insurance
15	Insurance (other than health)	Professional or general liability, business property
16a, 16b	Interest	Business loan or business credit card interest	Mortgage interest on a business property is 16a
17	Legal and professional services	Accountant, attorney, tax prep for the business part of your return
18	Office expense	Office supplies and postage
19	Pension and profit-sharing plans	Contributions for employees	Your own SEP goes on Schedule 1, line 16
20a	Rent or lease: vehicles, machinery, equipment	Leased camera gear, equipment rental
20b	Rent or lease: other business property	Coworking membership, studio or office rent	Home rent belongs on line 30
21	Repairs and maintenance	Laptop repair, equipment servicing	Improvements are depreciated, not repaired
22	Supplies	Materials and small tools used up during the year
23	Taxes and licenses	City business license, state fees, employer payroll taxes	No federal income tax or self-employment tax
24a	Travel	Airfare, hotel and rides when away from your tax home
24b	Deductible meals	Client meals, meals while traveling for work	Generally 50% of the cost
25	Utilities	Utilities at an office or studio, a second business phone line	Home utilities go on line 30 through Form 8829
26	Wages	W-2 payroll for employees	Less employment credits
27a	Energy efficient commercial buildings	Form 7205 deduction	Rare for freelancers
27b	Other expenses (Part V)	Software subscriptions, bank fees, professional dues, business courses	List each type and amount in Part V
30	Business use of home	Form 8829, or the simplified method	Don’t report home office costs on any other line

Income comes first, in Part I: everything you were paid goes on line 1 (gross receipts), whether or not you got a 1099-NEC or 1099-K. If you sell physical products, the cost of those goods is figured in Part III and goes on line 4.

Rules that trip freelancers up

1. Car costs: pick a method. You can use the standard mileage rate only if you chose it in the first year you used the car for business (for a leased car, for the whole lease) and haven’t claimed section 179, bonus or accelerated depreciation on it, and you don’t use five or more vehicles for business at the same time. With the standard mileage rate, multiply business miles by the rate and add parking fees and tolls. You then can’t also deduct gas, insurance, depreciation or lease payments for that car. For 2026 the IRS business rate is 72.5 cents a mile from January to June and 76 cents from July to December (IRS standard mileage rates). For 2025 it was 70 cents.
2. Meals are generally 50%. Enter only the deductible part on line 24b.
3. Equipment over a year of useful life is depreciated. The instructions allow a de minimis safe harbor: if you don’t have an audited financial statement, you can generally elect to deduct items up to $2,500 each instead of depreciating them.
4. Home office lives on line 30 only. Use Form 8829, or the simplified method: $5 per square foot of the area used regularly and exclusively for business, up to 300 square feet (a $1,500 maximum).
5. Your own benefits and taxes are not Schedule C expenses. Your health insurance (Schedule 1, line 17), your SEP contributions (Schedule 1, line 16) and half of your self-employment tax (Schedule 1, line 15) are deducted elsewhere. Fines and penalties paid to a government are not deductible at all.

Worked example: a freelance designer’s 2026 Schedule C

Fictional numbers. Alex, a sole-proprietor designer who uses the cash method, received $85,000 from clients in 2026 (gross, before the platform fees on line 10; invoices still unpaid at year end don’t count until paid) and has no W-2 job. Alex works from a 150-square-foot spare room used regularly and only for the business all year, and it is Alex’s principal place of business (no other fixed office), and has used the standard mileage rate on the car since first using it for business.

Line	Item	Amount
1, 7	Gross receipts (no returns, no goods sold)	$85,000
8	Instagram and LinkedIn ads	$600
9	2,000 miles × $0.725 (Jan to Jun) + 2,000 miles × $0.76 (Jul to Dec)	$2,970
10	Freelance platform fees	$1,700
11	Subcontracted illustrator	$2,500
15	Professional liability insurance	$480
17	Tax prep for the business part of the return	$450
18	Printer ink, paper, postage	$220
22	Sketchbooks, art materials	$300
23	City business license	$150
24a	Conference airfare and hotel	$1,200
24b	Client meals with Alex present, not lavish, billed separately from any entertainment ($400 × 50%)	$200
27b	Design software subscriptions ($1,140) and professional dues ($260)	$1,400
28	Total expenses	$12,170
29	Tentative profit ($85,000 − $12,170)	$72,830
30	Home office, simplified: 150 sq ft × $5	$750
31	Net profit	$72,080

Line 31 goes to Schedule 1, line 3 and Schedule SE, line 2. With no W-2 wages using up the $184,500 Social Security wage base, self-employment tax on it is $72,080 × 92.35% × 15.3% = $10,184.58, before any income tax (how self-employment tax works).

Why categorizing matters for your quarterly payments: every $1,000 of real expenses you forget to record adds about $141 of self-employment tax ($1,000 × 92.35% × 15.3%) while your own wages plus self-employment earnings are under the Social Security wage base (about $27 above it, the Medicare part only). Separately, the 0.9% Additional Medicare Tax adds about $8 more per $1,000 once Medicare wages and self-employment earnings pass $200,000 (single or head of household), $250,000 (married filing jointly, counting both spouses) or $125,000 (married filing separately). The two limits work independently: a spouse’s wages can push you over the Additional Medicare threshold but never use up your own Social Security wage base, so it can be about $150 per $1,000. Plus income tax at your bracket. Tracking expenses by line all year gives you a smaller, more accurate profit to base each estimated payment on, and a ready-made Schedule C in April.

How to keep your categories straight all year

• Record each expense when you pay it, with the date, payee, amount, line and a receipt. The IRS expects records that back up each amount.
• Use one card or account for business so nothing gets lost in personal spending.
• Driving for a delivery app? See DoorDash quarterly taxes for a mileage-heavy example.
• Log miles as you drive. Business miles, commuting miles and total miles all go in Part IV of the form if you claim car expenses and don’t have to file Form 4562.
• Check your profit each quarter and set aside tax from it. See how much to set aside for taxes on 1099 income and the estimated tax due dates.
• Want these lines in a spreadsheet? See how to build a Schedule C template in Excel or Google Sheets.
• Comparing tools? See Schedule C spreadsheet vs QuickBooks vs Keeper and the best quarterly estimated tax spreadsheets.

FAQ

What are the Schedule C expense categories?

Part II of Schedule C lists advertising, car and truck, commissions and fees, contract labor, depletion, depreciation and section 179, employee benefits, insurance, interest, legal and professional services, office expense, pension plans, rent or lease, repairs, supplies, taxes and licenses, travel, meals, utilities, wages, the energy efficient buildings deduction and other expenses. Home office goes on line 30.

Where do software subscriptions go on Schedule C?

There is no software line. Most freelancers list subscriptions by name in Part V, Other expenses, which carries to line 27b. Whatever you choose, use the same line every year. Software you buy outright and use for more than a year may need to be depreciated on line 13 instead.

Can I deduct my health insurance on Schedule C?

Not on Schedule C. If you are self-employed, your own health insurance premiums usually go on Schedule 1 (Form 1040), line 17. Line 14 is only for benefit programs for your employees.

Is self-employment tax a Schedule C expense?

No. The Schedule C instructions say you can't deduct federal income tax or self-employment tax on line 23. You deduct half of your self-employment tax on Schedule 1, line 15 instead.

Does it matter which line I use if the total is the same?

Your net profit and tax come out the same, but the right line matters for limits (meals are generally 50%), for forms that must be attached (Form 4562, Form 8829) and for a clean record if the IRS asks. Keep it consistent from year to year.
