The cost to incorporate in California is $105.00, and filing takes around three months; for an additional fee, filing can be rushed to around three weeks, and for yet another level of filing fee, your business can incorporate in California in as little as 24 hours.

A business incorporating in California is governed by various provisions found in the California Corporations Code; a copy of this Code is available through the Secretary of State's office, the government office that registers and maintains corporate entities.

Also available through the Secretary of State are other types of business filings your corporation may need throughout its life: Statement of Information forms, amendment forms, corporate merger forms, and other filings, as well as request forms for certificates and other copies of filed documents.
