Understanding Small Business Taxes The taxes imposed on small businesses vary by structure, revenue, and geographical location, as the IRS treats businesses differently.
1. Business Structures and Taxes Your tax obligations change based on how your business is set up, as follows:
● Owner of a Sole Proprietorship As an owner, the business’s revenue gets listed on your personal tax return (on a Schedule C attachment). Furthermore, you have to pay income tax and self-employment tax. ● Partner in a Partnership The partnership firms pay an informational return, but the partnership’s profits get passed on to the personal tax returns of the partners. ● Member of an LLC (Limited Liability Company) An LLC can get taxed in three ways: as a sole proprietorship, as a partnership, or as a corporation, depending on the member-managed vs. manager-managed elections. ● Shareholder of an S corporation The profits from the corporation get passed on to the owners, but you can also divide up an owner’s salary and an owner’s distributions, which can help reduce self-employment taxes. ● Shareholder of a C-corporation The corporation pays corporate income taxes, and the owners also get taxed on the dividends (i.e., there’s double taxation of corporate profits).

Return of Partnership Income). The partnership itself does not pay income tax, but each partner receives a Schedule K-1 showing their share of profits or losses to report on their personal return. ● S Corporations file Form 1120-S. Similar to partnerships, income passes through to shareholders, who receive a Schedule K-1. ● C Corporations file Form 1120 (U.S. Corporation Income Tax Return) and pay taxes at the corporate level. ● If your business has employees, you’ll also file payroll-related forms such as Form 941 (quarterly payroll taxes) and Form W-2 for employees. Filing the right forms on time keeps your business compliant and helps avoid IRS penalties.
