How is income from a sole proprietorship reported for tax purposes?

• A. On Form 1120 (corporate tax return)
• B. On Schedule K-1 attached to a partnership
• C. On Schedule C of the owner's personal tax return
• D. On Form 2553 to elect S-Corp status

Answer: (C)

In a sole proprietorship, the business isn’t treated as a separate tax entity. All income and expenses flow directly to the owner, so the business's results are reported on Schedule C (Profit or Loss from Business) attached to the owner’s personal tax return. The net profit or loss from Schedule C then becomes part of the owner's Form 1040 as ordinary income. If there is profit, the owner also owes self-employment tax, calculated on Schedule SE, using the net earnings from self-employment (which start from the Schedule C profit).

This is why Schedule C on the individual's personal return is the appropriate reporting method. Form 1120 is for corporate tax returns, which don’t apply to a sole proprietorship. Schedule K-1 is used to report a partner’s or shareholder’s share of income from partnerships or S corporations, not for a sole proprietorship. Form 2553 is the election form to treat a corporation as an S corporation, which changes the tax framework but isn’t how income from a sole proprietorship is reported.
