Schedule C Basics for Freelancers

Schedule C is the form where freelancers, sole proprietors, and single-member LLC owners report their self-employment income and expenses. It attaches to your Form 1040 and feeds the SE tax calculation on Schedule SE. Get it right and you keep money. Get it wrong and you either overpay (most common) or trigger an audit (less common but worse).

Who files Schedule C?

• Sole proprietors (most freelancers default to this).
• Single-member LLC owners who haven't elected corporate taxation.
• Statutory employees (limited cases — see Form W-2 box 13).
• Anyone earning $400+ in net self-employment income in a year.

Multi-member LLCs and partnerships file Form 1065, not Schedule C. S-corps file Form 1120-S. C-corps file 1120. If you're a single-member LLC and have done nothing special with the IRS, you're a "disregarded entity" — file Schedule C.

The structure of Schedule C

The form has five parts. Most freelancers only fill out the first three.

• Part I — Income. Gross receipts, returns, and a single net "gross income" number.
• Part II — Expenses. The big section. ~20 categorized expense lines (lines 8–27) plus "Other expenses" at the bottom.
• Part III — Cost of Goods Sold. Only relevant if you sell physical inventory.
• Part IV — Vehicle info. If you claim mileage on Line 9, fill this in.
• Part V — Other expenses. Itemize anything that didn't fit a Part II category.

Part I: Reporting income

Add up every dollar that flowed into your business in the calendar year. This includes:

• 1099-NEC forms you received from clients (most common).
• 1099-K forms from PayPal, Stripe, Etsy, Uber, etc. ($20,000 + 200 transactions for 2026 after OBBBA reverted the step-down).
• Cash and check payments — these don't trigger 1099s but you still owe tax on them.
• Crypto received as payment for services (taxable at fair market value when received).

You report gross income, then subtract returns and allowances (rare for service businesses). The net number flows to Part II.

Part II: The expense lines that matter

Most freelancers use only a handful of these lines. The big ones:

• Line 8 — Advertising. Ads, SEO services, business cards, sponsored content.
• Line 9 — Car and truck expenses. Either standard mileage ($0.725/mi in 2026) or actual expenses. Pick one and stick with it.
• Line 11 — Contract labor. Money paid to other contractors. Issue them 1099-NECs if over $2,000/year for TY 2026 (or $600/year for TY 2025 and earlier).
• Line 13 — Depreciation. Big purchases (computers, equipment) spread over multiple years. Section 179 lets you expense up to ~$2.56M in year 1.
• Line 17 — Legal and professional services. Lawyer, accountant, bookkeeper.
• Line 18 — Office expense. Stationery, postage, small supplies.
• Line 22 — Supplies. Materials consumed in the course of business.
• Line 24a/24b — Travel and meals. 24a is travel away from home overnight. 24b is business meals (50% deductible).
• Line 25 — Utilities. Internet, phone, electric — only the business portion.
• Line 27a — Other expenses. Itemized in Part V.

Home office deduction (separate)

Home office expenses get reported on Form 8829, then flow to Schedule C Line 30. There are two methods: simplified ($5/sq ft up to 300 sq ft, max $1,500) or actual (percentage of rent/utilities/insurance based on home office square footage). See our home office deduction guide.

Common mistakes that cost money

• Skipping legitimate deductions. Most new freelancers under-deduct. Software subscriptions, courses, conference fees, professional dues — all deductible.
• Mixing personal and business. One business bank account, one business credit card. Reconstructing personal-account spending at year-end is a nightmare.
• Wrong principal business code. Top of Schedule C asks for a 6-digit code. Use the IRS list — pick the closest match. Wrong codes can flag returns.
• Aggressive home office. The space must be exclusively used for business. A couch in the corner of a living room doesn't qualify.
• Not tracking mileage in real time. Reconstructing months later via Google Maps history works, but a contemporaneous log holds up better in audit.

Net profit flows to two places

The bottom line of Schedule C — Line 31 net profit — feeds two downstream forms:

1. Schedule SE. Calculates your 15.3% self-employment tax. Full SE tax breakdown here.
2. Form 1040 Line 8a. Adds your business income to your total income for federal tax bracket calculation.

Software vs. by-hand

Most freelancers use software (TurboTax Self-Employed, H&R Block, FreeTaxUSA, TaxAct) or work with a CPA. By-hand filling is possible — the IRS publishes the form free at irs.gov — but software catches missed deductions and warns about audit triggers. Your time is worth more than $50.

Line-by-line expense walkthrough (Part II)

The 27 expense lines in Part II are where freelancers either claim everything they're owed or leave money on the table. Quick guide to the lines most freelancers use:

• Line 8 — Advertising. Facebook ads, Google ads, business cards, website hosting, SEO services, sponsored content. Include domain renewals.
• Line 9 — Car and truck expenses. Either standard mileage (see our mileage guide) or actual vehicle expenses. Pick one and stick with it for the year.
• Line 10 — Commissions and fees. Platform commissions (Upwork, Fiverr, Etsy), payment processor fees you absorb, referral fees paid to others.
• Line 11 — Contract labor. Payments to subcontractors and freelancers you hire. If you paid anyone $2,000+ in 2026 (post-OBBBA threshold), issue them a 1099-NEC.
• Line 13 — Depreciation. From Form 4562. Computers, equipment, vehicles, machinery. Section 179 / bonus depreciation flow here.
• Line 14 — Employee benefit programs. Only if you have W-2 employees. Most solo freelancers leave blank.
• Line 15 — Insurance (other than health). Business liability, E&O, professional indemnity, equipment insurance. NOT your personal health insurance — that goes on Schedule 1 Line 17 as the self-employed health insurance deduction.
• Line 16a/16b — Interest. Mortgage interest on business property (16a) or other business loan interest (16b).
• Line 17 — Legal and professional services. CPA fees, business attorney fees, bookkeeping services. NOT personal tax prep on Form 1040 (that's a miscellaneous itemized deduction, suspended through 2025+).
• Line 18 — Office expense. Postage, business stationery, small consumables. Distinct from supplies.
• Line 19 — Pension and profit-sharing. Solo 401(k) employer-side contributions, SEP-IRA contributions for self. Not your own deferral (that's Schedule 1 Line 16).
• Line 20a/20b — Rent. Vehicle rentals (20a) or office/equipment rent (20b). Coworking space monthly fees go here.
• Line 21 — Repairs and maintenance. Equipment repair, computer fixes. Capital improvements depreciate (Line 13).
• Line 22 — Supplies. Items consumed within a year — paper, ink, batteries, small tools under $200. Software subscriptions can go here.
• Line 23 — Taxes and licenses. Business license fees, state franchise tax, sales tax YOU paid (not sales tax collected from customers).
• Line 24a/24b/24c — Travel and meals. 24a is business travel (airfare, lodging, ground transport — 100% deductible). 24b is meals (50% deductible, with limited 100% exceptions). 24c is no longer used.
• Line 25 — Utilities. Business-only utilities if separately metered (rare). Most utility deduction for home-based freelancers flows through home office deduction on Line 30 instead.
• Line 26 — Wages. Only if you have W-2 employees. Most freelancers leave blank.
• Line 27a — Other expenses. Anything that doesn't fit cleanly above: bank fees, online subscriptions (Adobe, Notion, Slack), professional dues, education/training, software not on Line 22. Itemize on the included worksheet.
• Line 30 — Home office (simplified) OR via Form 8829. See home office guide.

Cost of Goods Sold (Part III) — only if you sell products

Service-only freelancers (writers, designers, consultants, coaches) leave Part III blank entirely. If you sell physical products (Etsy, e-commerce, art prints, branded merchandise), Part III calculates Cost of Goods Sold (COGS):

• Line 33 — Method: typically "cost" for small sellers (FIFO inventory tracking). Specialized methods (LCM, gross profit) are unusual at small scale.
• Line 35 — Inventory at beginning of year. What you had on hand Jan 1 (carry forward from prior year's Line 41).
• Line 36 — Purchases. Wholesale/raw materials you bought during the year.
• Line 37 — Cost of labor. Production labor (not selling/admin labor — that's Line 26).
• Line 38 — Materials and supplies. Direct production materials (different from Line 22 Supplies).
• Line 39 — Other costs. Shipping IN (cost of goods shipped to you), packaging materials.
• Line 41 — Inventory at end of year. Year-end remaining stock. This subtracts from total above to give COGS.
• Line 42 — COGS flows to Part I Line 4, reducing gross receipts to gross profit.

Common Schedule C mistakes that trigger IRS scrutiny

• Round numbers everywhere. Reporting "$5,000 supplies, $3,000 office expense, $10,000 advertising" with no detail behind it triggers automated audit flags. Real expenses have non-round totals — $4,837, $2,956, $9,481.
• Hobby income misclassified as business. If you've shown a net loss every year for 5+ years with no upward trend, the IRS may reclassify as hobby and disallow expense deductions. See our hobby-vs-business guide.
• Mixing personal and business on Schedule C. Deducting your personal cell phone, personal car commuting, personal gym membership — all common mistakes. Each item should pass the "ordinary and necessary for THIS specific business" test.
• Claiming 100% business-use on a single personal vehicle. Statistical outlier; the IRS knows most freelancers also use their car for groceries and family.
• Travel deduction for "vacation with business component". If the primary purpose of a trip was vacation, the lodging/meals/airfare aren't deductible. Tacking on one client meeting doesn't convert a vacation into a business trip.
• Forgetting Form 1099-NEC obligations. If you paid contractors $2,000+ in 2026 and didn't issue 1099s by January 31, 2027, you owe $290 per missed form in penalties (and the IRS sometimes asks why expenses on Line 11 don't reconcile to 1099-NEC filings).

Frequently asked questions

I have two unrelated side businesses. Do I file one Schedule C or two?
Two — one Schedule C per distinct business. A freelance writer and an Etsy print shop are separate businesses even if the same person runs both. Each gets its own Schedule C with its own income and expenses. Combined net income flows to Schedule SE and Form 1040.

What's the difference between Schedule C and Schedule C-EZ?
Schedule C-EZ was discontinued by the IRS after 2018. As of 2026, everyone uses the full Schedule C regardless of business size.

My net Schedule C is negative. What happens?
A net loss flows to Form 1040 Line 8a as a negative number, reducing your AGI. Losses are deductible against other income (W-2 wages, spouse's income). Caveat: chronic losses (3+ years without profit) raise hobby-loss questions. Loss is also limited if the activity is "passive" rather than active — solo freelancers are virtually always active.

Can I file Schedule C if I'm an LLC?
Yes — a single-member LLC is a "disregarded entity" for federal tax by default. You file Schedule C just like a sole proprietor. The LLC matters for state legal protection but doesn't change federal income tax filing. Multi-member LLCs file Form 1065 (partnership return) instead. See our LLC vs sole prop guide.

I just started my business in November. Do I file Schedule C for 2 months of activity?
Yes. Any business income — even from one client in November — requires a Schedule C if total net is $400+. You report only the months active; there's no minimum activity duration. The form has no proration mechanic; you just enter actual income and actual expenses for whatever portion of the year you were operating.

The bottom line

Schedule C is two parts: how much money came in, how much you spent on the business. The 27 expense lines cover almost every situation; Part III only matters if you sell physical products. The biggest source of left-on-the-table money is forgetting deductions — keep a single business bank account, log mileage as you drive, revisit the expense lines quarterly, and reconcile every December against your bank statements so April isn't a scramble.
