Limited Liability Companies Treated as S Corporations The LLC will also be treated as an S corporation for the state and must file Form 100S (California S Corporation Franchise or Income Tax Return). California and federal laws treat these companies as corporations subject to California corporation tax law.
Because of the one-class-of-stock restriction, an S corporation cannot allocate losses or income to specific shareholders. Allocation of income and loss is governed by stock ownership, unlike partnerships or LLCs taxed as partnerships where the allocation can be set in the partnership agreement or operating agreement.
LLC taxed as an S corporation First, an LLC would need to elect to be taxed as a corporation by filing Form 8832, Entity Classification Election. After that, an LLC can then file a Form 2553, Election by a Small Business Corporation, to elect tax treatment as an S corporation.
