What's Next After Filing

Once your S-Corp is officially formed, you'll want to complete these important steps:

  • Elect S-Corporation Status with the IRSFile IRS Form 2553 (Election by a Small Business Corporation) to elect federal S-Corp tax status. This must be filed no later than 2 months and 15 days after the beginning of the tax year in which the election is to take effect, and all shareholders must sign the form.
  • Create Corporate Bylaws and Hold Organizational MeetingDraft corporate bylaws governing the internal operations of the corporation, then hold an organizational meeting of the board of directors to adopt bylaws, appoint officers, authorize issuance of shares, and address initial corporate matters. California does not require bylaws to be filed with the state.
  • Obtain EIN, Licenses, and Open Bank AccountObtain a federal Employer Identification Number (EIN) from the IRS at no cost, register with the California Franchise Tax Board, obtain any required state and local business licenses or permits, and open a dedicated corporate bank account to maintain proper separation of corporate and personal finances.

Advantages

  • Pass-through taxation avoids federal double taxation, with income and losses reported on shareholders' personal tax returns
  • Shareholders who are active employees can reduce self-employment taxes by splitting income between reasonable salary and distributions
  • Provides strong personal liability protection for shareholders, separating personal assets from business debts and liabilities
  • Enhances business credibility and makes it easier to attract investors, obtain financing, and enter contracts compared to sole proprietorships or partnerships

Considerations

  • California imposes a minimum $800 annual franchise tax and a 1.5% net income tax on all S-Corporations regardless of profitability, making it more costly than in many other states
  • S-Corp status has strict federal eligibility restrictions: limited to 100 shareholders, only one class of stock allowed, and shareholders must be U.S. citizens or resident aliens
  • Greater administrative burden compared to LLCs, including requirements for a board of directors, corporate bylaws, regular meetings, and detailed recordkeeping to maintain corporate formality

Annual Obligations

Franchise Tax:$800
Annual Report Fee:$25
Report Due:Statement of Information due every year by the last day of the anniversary month of incorporation
California S-Corporations are subject to a minimum franchise tax of $800 per year, payable to the California Franchise Tax Board, even if the business has no income. S-Corps also pay a 1.5% net income tax on California-sourced income (minimum $800). The annual Statement of Information (Form SI-550) costs $25 and is due each year. The first-year $800 franchise tax is due by the 15th day of the 4th month after the corporation's tax year begins. California does not fully conform to federal S-Corp rules; California requires a separate state S-Corp election via FTB Form 3560.
