Schedule C Walkthrough: Step-by-Step for Freelancers (2025)
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.
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 โ Income
Part I is where you report your total gross income before any deductions.
| Line | What Goes Here | Example |
|---|---|---|
| Line 1 | Gross receipts or sales. Total income received for services or products โ 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 |
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 โ you should reconcile this against your actual net income and deduct platform fees on Line 10 (Commissions and Fees).
Part II โ Expenses
Part II has 28 expense lines. You only fill in what applies to you โ leave the rest blank. Here are the most important 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 (ร $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 โ 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 โ 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 โ separate from travel |
| 25 | Utilities | Utilities for dedicated business space (not home office โ that's Line 30) |
| 26 | Wages | Wages paid to W-2 employees only (not contractors โ 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 โ 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 28โ31: Calculating Net Profit or Loss
| Line | What It Is |
|---|---|
| 28 | Total expenses. Sum of Lines 8โ27a (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" โ 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 โ 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 โ 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 โ your mileage log
- Is the evidence written? Yes โ 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:
| Method | Calculation | Limit |
|---|---|---|
| Simplified | $5 ร sq ft of dedicated office space | Max 300 sq ft = $1,500 |
| Regular (Form 8829) | Office sq ft รท total home sq ft ร home expenses (rent/mortgage interest, utilities, insurance, repairs) | Cannot exceed net profit |
The simplified method is easier โ 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 โ 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.
