Schedule C Walkthrough: Step-by-Step for Freelancers (2025)

📅 Updated March 2026 ⏱️ 15 min read 🏷️ 2025 Tax Filing

Schedule C (officially "Profit or Loss from Business") is the tax form where freelancers, independent contractors, and sole proprietors report their business income and deductible expenses. The net profit (or loss) from Schedule C flows to your Form 1040 and is subject to both income tax and self-employment tax. Here's how to fill it out correctly.

Good News: If you earn less than $5,000 in gross income and have no inventory, home office deduction, or employees, you may be eligible to use the simpler Schedule C-EZ instead. Most freelancers, however, will use the standard Schedule C.

What Is Schedule C?

Schedule C is a one-page IRS form attached to your personal Form 1040. Every sole proprietor, single-member LLC taxed as a disregarded entity, and freelancer uses it to:

Report all gross business income (1099-NEC, 1099-K, cash payments)
Deduct all ordinary and necessary business expenses
Calculate net profit or loss
Pass that net profit to Schedule SE for self-employment tax calculation

If you have multiple businesses, you file a separate Schedule C for each one.

Who Needs to File Schedule C?

You must file Schedule C if you are:

A freelancer or independent contractor who received any 1099-NEC or 1099-K
A sole proprietor running any type of business
A single-member LLC that hasn't elected S-corp or C-corp taxation
A gig worker (rideshare, delivery, TaskRabbit, etc.)
Anyone with self-employment income of $400 or more

Partners in a partnership file Schedule E instead. S-corps and C-corps file their own corporate returns.

Part I — Income

Part I is where you report your total gross income before any deductions.

Part I — Income Lines

Line	What Goes Here	Example
Line 1	Gross receipts or sales. Total income received for services or products — all your 1099s, invoices paid, and cash.	$95,000
Line 2	Returns and allowances. Refunds you issued to clients.	-$500
Line 3	Subtract line 2 from line 1. Net gross receipts.	$94,500
Line 4	Cost of Goods Sold (from Part III). For product-based businesses.	$0 (most freelancers)
Line 5	Gross profit. Line 3 minus Line 4.	$94,500
Line 6	Other income. Bartering, rents received, prizes, and anything not in Line 1.	$0
Line 7	Gross income. Line 5 + Line 6. This is your top-line revenue.	$94,500

Important: Report ALL income, even if you didn't receive a 1099-NEC. If a client pays you cash, Venmo, or Zelle and doesn't issue a 1099, you still must report it. Underreporting income is the #1 tax audit trigger.

What About 1099-K?

If you use payment processors like PayPal, Stripe, Square, or Venmo for Business and receive over $5,000 in 2025 (the threshold is dropping to $600 in future years), you may receive a 1099-K. The 1099-K includes gross receipts including any platform fees — you should reconcile this against your actual net income and deduct platform fees on Line 10 (Commissions and Fees).

Part II — Expenses

Part II has 28 expense lines. You only fill in what applies to you — leave the rest blank. Here are the most important lines for freelancers:

Part II — Key Expense Lines for Freelancers

Line	Expense Category	What to Include
8	Advertising	Google Ads, Facebook Ads, business cards, website ads, promotions
9	Car and Truck Expenses	Business mileage (× $0.70) OR actual vehicle expenses (see Part IV)
10	Commissions and Fees	Payments to subcontractors, platform fees (Upwork, Fiverr, Stripe, PayPal)
11	Contract Labor	Payments to independent contractors (require 1099-NEC if $600+)
13	Depreciation (Form 4562)	Depreciation on equipment, computers, furniture; also Section 179 expensing
14	Employee Benefits	Health insurance, retirement plans for employees (not yourself)
15	Insurance (other)	General liability, E&O, property insurance — NOT health insurance for yourself
16b	Interest (Other)	Business loan interest, business credit card interest
17	Legal and Professional Services	Accountant, attorney, bookkeeper fees for business matters
18	Office Expense	Supplies, postage, printer ink, paper, small equipment
20a	Rent or Lease (Vehicles)	Vehicle lease payments for business use
20b	Rent or Lease (Other)	Office rent, coworking space, storage unit rent
22	Supplies	Materials used in delivering services — job-specific supplies
23	Taxes and Licenses	Business licenses, state/local taxes, employer payroll taxes
24a	Travel	Business flights, hotels, rental cars (not meals)
24b	Deductible Meals	50% of business meals — separate from travel
25	Utilities	Utilities for dedicated business space (not home office — that's Line 30)
26	Wages	Wages paid to W-2 employees only (not contractors — that's Line 11)
27a	Other Expenses (Part V)	Software subscriptions, dues, education, phone/internet, bank fees
30	Home Office Deduction	From Form 8829 or simplified method ($5/sq ft, max $1,500)

Part V — Other Expenses

Line 27a refers to Part V at the bottom of the form where you list "other expenses" that don't fit the named categories. Common items for freelancers include:

Software subscriptions (Adobe, Quickbooks, etc.)
Professional association dues and memberships
Business portion of phone and internet
Online education and training
Business banking fees
Client gifts (up to $25 per recipient per year)
Books and trade publications

Lines 28–31: Calculating Net Profit or Loss

Bottom-Line Calculation

Line	What It Is
28	Total expenses. Sum of Lines 8–27a (and Line 30 for home office)
29	Tentative profit. Line 7 minus Line 28
30	Home office deduction (if using Form 8829)
31	Net profit or (loss). Line 29 minus Line 30. This flows to your 1040 and Schedule SE.
32	If you have a loss, you must check whether the loss is "at risk" — most freelancers check box 32a (all investment at risk)

If Line 31 is positive, you have net profit. This amount is added to your other income on Form 1040 and is subject to self-employment tax. If negative (a loss), it may reduce your other income, subject to passive activity loss rules.

Part III — Cost of Goods Sold

Part III only applies to businesses that sell products (physical or digital goods). Most pure service freelancers (designers, writers, consultants, etc.) skip this section entirely. If you sell products:

Line 33: Inventory method (cost, retail, etc.)
Line 35: Beginning inventory (prior year ending inventory)
Line 36: Purchases (goods bought for resale)
Line 40: Ending inventory
Line 42: Cost of goods sold (flows to Part I, Line 4)

Part IV — Vehicle Information

If you claim vehicle expenses on Line 9, you must complete Part IV with details about your vehicle. Key questions:

When was the vehicle placed in service? First date you used it for business
Total miles driven? Total, business miles, commute miles, other personal miles
Do you have another vehicle? IRS requires you to have another vehicle available for personal use
Do you have evidence of business use? Yes — your mileage log
Is the evidence written? Yes — and you should keep it for at least 3 years

Home Office (Line 30 / Form 8829)

The home office deduction is calculated one of two ways:

Home Office Methods

Method	Calculation	Limit
Simplified	$5 × sq ft of dedicated office space	Max 300 sq ft = $1,500
Regular (Form 8829)	Office sq ft ÷ total home sq ft × home expenses (rent/mortgage interest, utilities, insurance, repairs)	Cannot exceed net profit

The simplified method is easier — enter the result directly on Line 30. The regular method requires filing Form 8829 and may produce a larger deduction if your home costs are high.

Common Schedule C Mistakes to Avoid

Not reporting all income. Every dollar received for services counts — whether you got a 1099 or not.
Deducting personal expenses. A vacation with one business meeting attached doesn't make the whole trip deductible. Be honest about business vs. personal.
Wrong vehicle method. If you choose actual expenses in Year 1, you can't switch to standard mileage later (for that vehicle). Think it through.
Forgetting start-up costs. If you started the business this year, up to $5,000 of startup expenses can be deducted immediately.
Confusing contractors and employees. Payments to subcontractors go on Line 11. W-2 wages go on Line 26. Don't mix them up.
Missing the home office deduction. It's the #1 missed deduction for remote freelancers. If you have a dedicated workspace, claim it.
Overlooking platform fees. If you use Upwork, Stripe, PayPal, or Fiverr, their fees are deductible on Line 10.
Claiming meals at 100%. Business meals are only 50% deductible. Don't deduct the full amount.

Quick Step-by-Step Summary

Gather your income documents. Collect all 1099-NEC, 1099-K forms received, plus your invoices and payment records for any income not covered by 1099s.

Total your gross income. Add all revenue from services, sales, and other business sources. Enter on Line 1.

Categorize your expenses. Go through your bank statements, credit card statements, and receipts. Assign each expense to the correct Schedule C line using Part II.

Calculate vehicle and home office deductions. Complete Part IV for vehicle use. Choose simplified or regular method for home office and enter on Line 30.

Total your expenses (Line 28). Sum all expense lines. Then subtract from gross income to get net profit on Line 31.

Transfer to Form 1040 and Schedule SE. Net profit from Line 31 flows to your 1040 (Schedule 1) and to Schedule SE for self-employment tax calculation.

Frequently Asked Questions

Do I need to attach receipts to my Schedule C?▼

No — you don't attach receipts to your return. But you must keep them for at least 3 years (6 years if significant underreporting is suspected). The IRS may ask for them in an audit. Digital records (photos, scans, accounting software exports) are acceptable.

What if I have a net loss on Schedule C?▼

A Schedule C loss can generally offset your other income (like W-2 wages from a day job), reducing your overall tax bill. However, if you show losses multiple years in a row, the IRS may classify your business as a hobby, which disallows most deductions. There's generally a presumption of business intent if you show profit in 3 of 5 consecutive years.

Should I use tax software or a CPA?▼

For straightforward freelance situations (one type of income, common expenses, no employees), tax software like TurboTax Self-Employed, H&R Block Premium, or TaxAct works well. If you have complex situations — multiple businesses, significant asset purchases, S-corp election, or substantial income — a CPA typically pays for itself in tax savings and peace of mind.

Do I need an EIN for Schedule C?▼

No — sole proprietors without employees can use their Social Security Number on Schedule C. However, an EIN is recommended for privacy (so clients don't have your SSN) and may be required if you have employees or certain retirement accounts. EINs are free and instant from the IRS website.
