Table of Contents

Definition

Schedule C (Form 1040) is the IRS form used by sole proprietors and single-member LLCs to report profit or loss from a business. It allows you to itemize business income and expenses on your individual tax return, calculating your net self-employment earnings subject to income and self-employment taxes.

Who Should File

  • Self-Employed Individuals: Freelancers, independent contractors, gig workers

  • Single-Member LLCs: Entities taxed as disregarded for federal income tax

  • Sole Proprietors: Anyone operating an unincorporated business or trade

If you earned net profit from these activities, you must file Schedule C with your Form 1040.

Common Deductible Expenses

  • Vehicle & Mileage: Business miles driven for client visits, deliveries, etc.

  • Home Office: Portion of rent, utilities, and internet used exclusively for business

  • Supplies & Equipment: Office supplies, tools, software subscriptions

  • Meals & Entertainment: 50% deduction for business meals with clients

  • Insurance & Licenses: Business insurance premiums and professional licenses

  • Advertising & Marketing: Website hosting, ads, trade-show fees

When to File

File Schedule C annually with your Form 1040 by the tax deadline. If you expect to owe more than $1,000 in self-employment tax, make estimated quarterly payments to avoid penalties.
