Schedule C – Profit or Loss from Business (Fillable PDF)

Schedule C (Form 1040) is the IRS form used by sole proprietors, single‑member LLCs, and independent contractors to report profit or loss from a business. Our fillable PDF lets you complete the form directly in your browser—no Adobe Acrobat or printer required.

What Is Schedule C and Who Needs It?

The Schedule C form captures income, expenses, cost of goods sold, and vehicle mileage for a trade or business. If you earned self‑employment income in the last tax year, you’ll likely need to file Schedule C with your Form 1040.

Key Sections of the Schedule C Form

• Part I – Income: Gross receipts, returns, and other income.
• Part II – Expenses: Advertising, car expenses, depreciation, supplies, and more.
• Part III – Cost of Goods Sold: Beginning inventory, purchases, and ending inventory.
• Part IV – Information About Your Vehicle: Mileage and expenses if you use a car for business.
• Part V – Other Expenses: Any additional costs not listed in Part II.

Common Mistakes & Tips

• Double‑check that all income is reported—missed cash sales can trigger an audit.
• Keep receipts for every expense; the IRS may request documentation.
• Use the correct expense categories; mis‑classifying can reduce your deduction.
• Don’t forget to fill out the vehicle information section if you claim mileage.
• Review the totals in Part I and Part II to ensure they balance before attaching to Form 1040.
