Frequently Asked Questions
To form a California S-Corp you file Articles of Incorporation (Form ARTS-GS) with the Secretary of State for a $100 fee, appoint a registered agent at creation, and file an initial Statement of Information (Form SI-200, $25) within 90 days. To be taxed as an S corporation you then file IRS Form 2553 no later than 2 months and 15 days after the start of the tax year the election should take effect.
California imposes a minimum franchise tax of $800 per year on S corporations, paid with Form 100S, the California S Corporation Franchise or Income Tax Return, due March 15 for calendar-year filers. Tax above the minimum is based on net income. Estimated payments are made quarterly with Form 100-ES on April 15, June 15, September 15 and December 15.
For calendar-year filers, the state Form 100S and the federal Form 1120S are both due March 15, and Schedule K-1s must be issued to shareholders by the same date. The annual Statement of Information (SI-200) is due by the end of the anniversary month of incorporation, and quarterly estimated payments fall on April 15, June 15, September 15 and December 15.
Within 15 days of employing the first worker the corporation must register with the California Employment Development Department using Form DE 1, the Registration Form for Commercial Employers. After that, it files the quarterly wage and contribution reports DE 9 and DE 9C, due the last day of the month following the end of each quarter, through the EDD's online reporting system.
To pursue federal contracts the corporation registers in the System for Award Management (SAM), which is free and renewed annually from the initial registration date. For California state contracts it registers in Cal eProcure, also free with annual renewal. Both registrations are prerequisites before bidding, in addition to standard tax, employment and sales permit compliance.
