Frequently Asked Questions

What is Schedule C and who files it?
Schedule C (Form 1040) reports profit or loss from a business operated as a sole proprietorship (or single-member LLC not electing otherwise). You file it with your Form 1040 if you have self-employment income. Income and expenses are reported by category; net profit is subject to income tax and self-employment tax.
What income do I report on Schedule C?
Report all gross income from the business: 1099-NEC and 1099-MISC income, payments from clients (cash, check, card, transfer), sales, and other business revenue. Keep invoices, payment records, and bank deposits to support the amounts reported.
What expenses can I deduct on Schedule C?
Ordinary and necessary business expenses are deductible. Common categories include cost of goods sold, advertising, car and truck, insurance, interest, office expense, supplies, contract labor, travel, meals (subject to limits), utilities, and home office (if you use the simplified or regular method). Keep receipts and records for each category.
Do I need records for the home office deduction?
Yes. For the regular method you need records of direct and indirect expenses (utilities, rent/mortgage interest, repairs, etc.) and the square footage of the office and home. For the simplified option you need the square footage of the office (max 300 sq ft). Our checklist covers both approaches.
