Key takeaways
- You file Schedule C if you run a business or practice a profession as a sole proprietor, with profit as your main purpose and regular activity (IRS Schedule C instructions).
- Part II lists expense lines 8 through 27b, plus line 30 for business use of your home. Each line needs its own supporting records.
- Most business meals on line 24b are only 50% deductible.
- Net profit from Schedule C is also the base for self-employment tax on Schedule SE.
What is Schedule C?
Schedule C is where a one-person business tells the IRS what it earned and what it spent. You attach it to your personal Form 1040. Part I covers income, starting with gross receipts on line 1. Part II lists expenses by category. Part III handles cost of goods sold for businesses with inventory, and Part IV covers vehicle information. Part V lists “other expenses” that don’t fit a named line.
The bottom line, net profit or loss on line 31, becomes part of your income tax and the base for self-employment tax.

Who files Schedule C
- Freelancers and independent contractors paid on 1099s or through apps
- Sole proprietors, including people with a side business on top of a W-2 job
- Single-member LLCs that haven’t elected to be taxed as a corporation
- Statutory employees (box 13 checked on their W-2)
- Qualifying spouses running a joint business who elect to be treated as two sole proprietors
A hobby or sporadic activity doesn’t qualify. The IRS looks for profit as your main purpose and work done with continuity and regularity. Multi-member LLCs and partnerships file Form 1065 instead, and corporations file their own returns.
Expense lines explained, with the receipts each needs
Here’s the Part II map. Use it to sort receipts during the year, not just in April.
| Line | What goes here | Receipts and records to keep |
|---|---|---|
| 8 Advertising | Ads, website hosting for marketing, business cards | Platform invoices, printer receipts |
| 9 Car and truck | Standard mileage rate or actual costs | Mileage log; parking and toll receipts; gas and repair receipts if using actual costs |
| 10 Commissions and fees | Platform fees, referral commissions | Platform statements, 1099-K fee summaries |
| 11 Contract labor | Payments to other freelancers | Invoices, payment records, W-9s; 1099-NEC if $2,000+ in 2026 |
| 13 Depreciation and section 179 | Computers, equipment, furniture | Purchase receipts showing date and cost (Form 4562) |
| 15 Insurance | Business liability, E&O, business property | Policy bills and payment confirmations |
| 17 Legal and professional | Accountant, lawyer, tax prep for the business | Invoices with paid confirmation |
| 18 Office expense | Postage, small office items | Store and online order receipts |
| 20a/20b Rent or lease | Equipment or vehicle leases; office or coworking rent | Lease agreement, monthly payment records |
| 22 Supplies | Materials used up in the business | Itemized receipts |
| 23 Taxes and licenses | Business licenses, permits, employer payroll taxes | Government receipts and notices |
| 24a Travel | Airfare, lodging, ground transport away from home | All lodging folios; receipts for other costs of $75 or more |
| 24b Meals | Business meals, usually 50% deductible | Receipt plus who attended and the business purpose |
| 25 Utilities | Business phone, internet, utilities at a business location | Monthly bills; business-use percentage |
| 27b Other expenses | Anything listed in Part V, such as subscriptions or education | Receipts plus a short description |
| 30 Business use of home | Home office | Square footage; rent, utility and insurance bills for the regular method |
Lines 12 (depletion), 14 (employee benefit programs), 16 (interest), 19 (pension plans for employees), 21 (repairs), 26 (wages) and 27a (energy-efficient commercial buildings) round out the list. If you sell products, the cost of inventory goes in Part III and reduces income on line 4, not in Part II.
Under IRS Publication 463, travel, gift and vehicle expenses need receipts for all lodging and for other expenses of $75 or more. For everything else, a receipt or invoice plus proof of payment is the standard substantiation.
Common Schedule C errors
- Line 1 lower than your 1099s. The IRS matches forms automatically. If amounts differ for a good reason, such as personal payments on a 1099-K, explain it.
- Personal costs mixed in. Family meals, everyday clothes and commuting don’t belong on Schedule C.
- Meals at 100%. Most business meals are limited to 50%.
- Everything dumped in “Other expenses.” Use the named lines where they fit. Large unexplained totals on line 27b invite questions.
- Home office without exclusive use. A kitchen table that’s also used for dinner doesn’t qualify.
- Deductions without records. An estimate isn’t a receipt. If you can’t prove it, you may lose it in an audit.
Receipts sorted the way Schedule C reads
Manage Receipt’s AI tax report groups your scanned receipts into deductible categories that line up with Schedule C, such as supplies, travel, meals and office expense. You can review each total with the receipts behind it before handing it to your tax preparer, instead of sorting a shoebox in April.

Who needs to file Schedule C?
Anyone who runs a business or practices a profession as a sole proprietor, including freelancers, gig workers, side-business owners and most single-member LLCs. The activity must be carried on regularly with profit as its main purpose. Statutory employees also use it. Partnerships and corporations file their own returns.
What expenses go on Schedule C?
Ordinary and necessary costs of running your business: advertising, car and truck expenses, contract labor, insurance, professional fees, office expense, rent, supplies, licenses, travel, 50% of most business meals, utilities, wages and depreciation. Home office costs go on line 30, and inventory costs go in Part III.
Do I need to file Schedule C if I made very little?
Generally yes, if you have business income. Schedule C is how you report it and claim expenses. Separately, if your net earnings from self-employment are $400 or more, you must also file Schedule SE and pay self-employment tax. Small amounts still count, so keep the receipts that reduce them.
Can I file Schedule C with a loss?
Yes. If expenses exceed income, Schedule C shows a net loss, which can usually offset other income such as wages. Keep strong records, because repeated losses can lead the IRS to question whether the activity is really a business rather than a hobby.
