Self-employment tax implies the business has which structure?

• A. Partnership
• B. C Corporation
• C. Sole proprietorship
• D. Limited liability company

Answer: (C)

Self-employment tax is the tax on the earnings of someone who works for themselves. This tax applies directly to the owner in a simple, single-owner structure where the business is not a separate taxable entity. In a sole proprietorship, the owner and the business are one and the same, so net earnings from the business are reported on the owner's return and are subject to self-employment tax. That direct link between owning the business and paying SE tax makes sole proprietorship the best fit for this concept.

In other structures, the tax treatment differs: a C corporation pays wages to employees (including the owner if they work as an employee) with payroll taxes, and corporate earnings beyond wages aren’t treated as self-employment income; partnerships and LLCs taxed as partnerships involve SE tax for the partners on their share of profits, but for a single-owner scenario, sole proprietorship is the clearest match.
