Schedule C – Profit or Loss From Business Guide

Schedule C (Form 1040) is used by self-employed individuals, independent contractors, freelancers, sole proprietors, and single-member LLC owners to report business income and expenses on their personal tax return. Proper preparation of Schedule C is important for accurately reporting income, maximizing deductions, and remaining compliant with IRS regulations.

At Z Tax & Accounting, we assist self-employed professionals and business owners in Irving, Las Colinas, Dallas, Plano, Arlington, Fort Worth, Coppell, Grand Prairie, Richardson, Carrollton, Euless, Bedford, Grapevine, Farmers Branch, and across the United States with Schedule C tax preparation, bookkeeping, tax planning, and business consulting services.

What Is Schedule C?

Schedule C is attached to IRS Form 1040 and reports income or loss from a sole proprietorship or single-member LLC. The form calculates taxable business income after deducting ordinary and necessary business expenses related to operating the business.

Many small business owners and independent workers use Schedule C because they operate without a separate corporate tax return.

Who Files Schedule C?

Schedule C is commonly filed by:

• Independent contractors

• Freelancers

• Gig economy workers

• Consultants

• Realtors® and brokers

• Truck drivers

• Online sellers and e-commerce businesses

• Delivery drivers

• Landlords providing substantial services

• Single-member LLC owners

• Self-employed professionals

Even part-time businesses or side income activities may require Schedule C reporting.
