You list gross receipts in Part I, deduct expenses in Part II, and arrive at net profit or loss on Line 31, which flows to your 1040 and Schedule SE.

Schedule C (Form 1040) is the IRS tax form sole proprietors use to report the profit or loss from a business they operated or a profession they practiced as a self-employed individual. Officially titled "Profit or Loss From Business (Sole Proprietorship)," it attaches to your annual Form 1040 and captures gross receipts, the cost of goods sold, and deductible business expenses such as advertising, supplies, vehicle costs, and home-office use. The net figure on Line 31 carries to Form 1040 and Schedule SE, where it determines both income tax and self-employment tax. Freelancers, gig workers, and single-member LLCs all rely on it. With JustFill you can fill Schedule C online free — the AI reads the form, places every line, and lets you type or dictate.
