If you are the sole owner of a business (operating as a sole proprietorship or a single member LLC disregarded as an entity for tax purposes) or operate as an independent contractor, you will need to file a Schedule C to report income or loss from your business activities. The Schedule C is attached to your Form 1040.

If your business has $400 or more of business income over and above expenses, you need to file a Schedule C or C-EZ, and a Schedule SE to pay self-employment tax, even if you would not otherwise have enough income to be required to file a tax return.

The latest version of the Schedule C form and instructions can be found on the IRS’ website.
