Filing taxes as a self-employed individual can feel overwhelming, especially when navigating the specific requirements for Washington DC, Maryland, and Virginia.

This guide breaks down the essentials of Schedule C tax filing for self-employed residents in these areas, offering clear steps, practical tips, and examples to help you file confidently.
What Is Schedule C and Who Needs It?
Schedule C, officially titled "Profit or Loss from Business," is a form used by sole proprietors and single-member LLCs to report income and expenses related to their business activities. If you are self-employed and earn income from your business, you must file Schedule C with your federal tax return (Form 1040).
Who Must File Schedule C?
Sole proprietors earning income from a trade or business.
Single-member LLCs treated as disregarded entities for tax purposes.
Independent contractors and freelancers.
Anyone running a business without forming a corporation or partnership.
If you live in DC, Maryland, or Virginia and operate a business, you will file Schedule C with your federal return and then report your income on your state tax return as well.
Key Sections of Schedule C Explained
Schedule C has several parts that help you report your business income and expenses accurately:
Part I: Income
Report your gross receipts or sales from your business here. This includes all income before expenses. For example, if you are a freelance graphic designer in Maryland and earned $50,000 in 2023, you enter that amount in this section.
Part II: Expenses
This section allows you to deduct business expenses such as:
Advertising
Car and truck expenses
Contract labor
Depreciation
Insurance
Office expenses
Supplies
Travel and meals (subject to limits)
Keeping detailed records and receipts is essential to justify these deductions if audited.
Part III to V: Cost of Goods Sold, Information on Your Vehicle, and Other Expenses
If your business sells products, you calculate the cost of goods sold here. If you use a vehicle for business, you provide details in Part IV. Part V is for any other expenses not listed in Part II.
