Schedule C

Schedule C — what it means, how it works, and a real example, explained without the jargon.

What is Schedule C?

Schedule C is where a sole proprietor or single-member LLC reports the income and expenses of their business, right alongside their personal 1040.

How it works

You list gross receipts at the top, subtract categorized expenses (supplies, advertising, mileage, home office, and so on), and the net profit on line 31 flows to your 1040 and to Schedule SE for self-employment tax. Good bookkeeping all year is what makes this form painless.

A quick example

A freelance photographer with $60,000 in revenue and $18,000 in gear, software, and travel reports a $42,000 net profit — and it's that $42,000, not the $60,000, that gets taxed.

What people get wrong

Every legitimate business expense you forget to claim is money left on the table. Track mileage, software subscriptions, and the home-office deduction — they add up fast and directly cut both your income and self-employment tax.
