Schedule C Expense Categories: Every Line, With the Receipt That Proves It
How Schedule C expenses work
Schedule C is where sole proprietors and single-member LLCs report business income and expenses. Part II holds the expense lines; anything ordinary and necessary without a line of its own is itemized in Part V and totaled on line 27b. If you sell products, what you paid for inventory goes in Part III (cost of goods sold), not in Part II. Your net profit (line 31) is what self-employment tax and income tax are figured on — the 1099 tax calculator shows what each dollar of deductions saves.
Every expense line, and the receipt that proves it
Advertising
Online ads, sponsored posts, business cards, flyers, trade-show booth fees.
Proof: Ad platform invoice or receipt showing the campaign and amount.
Car and truck expenses
Business use of your vehicle: either actual costs (gas, repairs, insurance) or the standard mileage rate, plus business parking and tolls either way.
Proof: Mileage log (date, miles, destination, purpose); gas and repair receipts if you use actual costs; parking and toll receipts.
Commissions and fees
Marketplace and platform fees, sales commissions you pay.
Proof: Platform fee statements (e.g. monthly payout reports).
Contract labor
Payments to independent contractors who aren’t your employees.
Proof: Contractor invoices, proof of payment, and a W-9 on file. For payments made in 2026, a 1099-NEC is generally due once you pay someone $2,000 or more ($600 for 2025).
Depletion
Natural resources such as timber or minerals. Rare for freelancers.
Proof: Property and production records.
Depreciation and section 179
The cost of equipment that lasts more than a year — laptop, camera, furniture, vehicle — recovered over time or expensed under section 179, figured on Form 4562.
Proof: Purchase receipt or invoice, date placed in service, and how much you use it for business. Keep until the tax period closes for the year you sell or dispose of it.
Employee benefit programs
Health, accident and dependent-care plans for your employees (not for you).
Proof: Plan invoices and payment records.

Interest on business loans and on business credit cards.
Proof: Loan or card statements showing interest charged.
Legal and professional services
Accountants, attorneys and tax preparers for the business.

Contributions for your employees (not your own retirement plan).
Proof: Plan statements.

The business share of leased cars, rented equipment and gear.
Proof: Lease agreement and payments.
Rent or lease: other business property
Office, studio, coworking membership, storage unit.

Taxes and licenses
Business licenses, permits, state sales tax you paid, the employer share of payroll taxes. Not federal income tax or self-employment tax.
Proof: License receipts, tax payment confirmations.
Travel
Overnight business travel away from your tax home: airfare, lodging, transport at the destination.
Proof: Itemized hotel folio (lodging always needs a receipt), tickets, and the business purpose of the trip.
Deductible meals
Business meals, generally limited to 50% of the cost.
Proof: Itemized receipt plus who attended and the business discussed.
Utilities
Utilities for business premises. For a home phone, only business costs above the base rate of the first line.
Proof: Utility bills; phone bills with business use noted.
Wages
Salaries and wages for employees (not draws you pay yourself).

Energy efficient commercial buildings
The section 179D deduction, on Form 7205. Rare for freelancers.

Proof: Receipts or statements for each item listed in Part V.
Business use of home
A space used regularly and exclusively for business, via Form 8829 or the simplified method ($5 per square foot, up to 300 square feet).
Proof: Measurements of the space and, for Form 8829, the home’s bills (rent or mortgage interest, utilities, insurance).
Line numbers follow the latest published Schedule C instructions (tax year 2025). Check the form for the year you file — the IRS occasionally renumbers lines.

| Half of self-employment tax | Schedule 1 adjustment, figured on Schedule SE. |
| Federal income tax and self-employment tax | Never deductible on line 23. |
| Commuting from home to a regular workplace | Personal, not business travel. |
| Clothing you could wear outside work | Not deductible; uniforms and protective gear can be. |

A worked example
A freelance designer’s month: an Adobe subscription ($59.99) goes on line 18 or in Part V as software; a client lunch ($64) goes on line 24b at $32; a conference hotel ($412 for two nights) goes on line 24a with the itemized folio; 140 business miles driven in August go on line 9 at 76¢ ($106.40) plus a $12 parking receipt; a $1,600 laptop goes on line 13 through Form 4562 (or is expensed under section 179). Each of those amounts is only as good as the receipt and note behind it.

Which lines Proofly maps automatically
The Proofly receipt scanner assigns each business receipt to one of nine lines from its category: advertising (8), car and truck (9), legal and professional (17), office expense (18), supplies (22), travel (24a), meals (24b, at 50%), utilities (25) and other expenses (27b). You can change any receipt’s category before it’s totaled. Lines like depreciation, contract labor or home office depend on facts a receipt doesn’t show, so those stay with you and your preparer.

What the Proofly receipt scanner does — and doesn’t
Does
- Reads merchant, date, line items, tax and payment method from a photo, with a confidence meter so you can correct it before saving
- Keeps personal and per-company receipts separate
- Maps business expenses to Schedule C lines (meals already at 50%)
- Exports an audit pack: every receipt image plus a ledger, as PDF, and CSV for QuickBooks or Xero
- Has a manual mileage log priced at the IRS rate for each trip’s date
Doesn’t
- File your taxes or give tax advice
- Sync live with QuickBooks or Xero (it’s CSV export)
- Pull transactions from your bank automatically
- Track your drives by GPS
- Guarantee how an audit turns out
Frequently asked questions
What are the Schedule C expense categories?
Part II of Schedule C lists lines 8 through 27b — advertising, car and truck, commissions, contract labor, depletion, depreciation, employee benefits, insurance, interest, legal and professional, office expense, pension plans, rent, repairs, supplies, taxes and licenses, travel, meals, utilities, wages and other expenses — plus line 30 for business use of your home.
Where do software subscriptions go on Schedule C?
There’s no software line. Many filers put small subscriptions on line 18 (office expense) or list them under other expenses (line 27b, Part V). What matters is choosing one consistently and keeping the receipts. Expensive software you own outright may be depreciated instead.
What’s the 2026 standard mileage rate?
For business miles in 2026 the IRS set 72.5 cents per mile from January 1 through June 30, and 76 cents per mile from July 1. Use the rate for the date of each trip, and add business parking and tolls on top.
How much of a business meal can I deduct?
Generally 50%. Enter the deductible half on line 24b and keep the itemized receipt with who attended and the business purpose.
Can I deduct my home office?
Yes, if a space is used regularly and exclusively for business. The simplified method gives $5 per square foot for up to 300 square feet; Form 8829 uses your actual home expenses. Either way the result goes on line 30.
Where does my health insurance go?
Not on Schedule C. Self-employed health insurance premiums generally go on Schedule 1 as an adjustment to income. Line 14 is only for benefit programs you provide to employees.
