Navigate Schedule C, the two-page form for sole proprietors, and understand accompanying IRS forms for accurate business tax filing. Learn about income, expenses, depreciation, and more.

A Schedule C consists of two pages. If your tax filing includes complex claims about your business's profits and losses, it's crucial to stay organized. Schedule C, titled "Profit or Loss from Business," serves as the foundational document for sole proprietors and single-member LLCs, connecting to various other forms depending on your business's transactions during the tax year.
This guide breaks down Schedule C's two core pages and explains common IRS forms that often accompany it. Understanding the complete picture ensures your tax return is comprehensive and accurate.
Each section of Schedule C calculates your final net profit or loss, which influences your overall income tax return on Form 1040 and often your self-employment tax. Let's look at how each part functions.
Page one focuses on calculating your gross income, where you report your earnings and the direct costs associated with producing the goods or services you sell.
The output of these sections determines your gross income (Line 7), a crucial figure that serves as the base for subtracting expenses on page two.
The second page details the costs of running your business that aren’t directly tied to producing your goods or services. This is the most detailed part of Schedule C, breaking down your operating expenses to calculate your net profit or loss.
A two-page Schedule C is often accompanied by additional forms based on your specific business circumstances to complete your tax return.
If your business acquires significant assets that last more than one year, like equipment or buildings, they are depreciated over time. The detailed calculations are done on Form 4562, which should be attached to your tax return.
If you operate your business out of your home, you may deduct expenses related to the business use of part of your home. This can be calculated using Form 8829, which details these expenses.
Sole proprietors must pay self-employment taxes, which include Social Security and Medicare. The net profits from Schedule C determine your liability, calculated on Schedule SE.
If your business has employees, you are responsible for additional forms such as Form 941 for quarterly federal tax returns and Form 940 for annual federal unemployment tax returns.
