California Franchise Tax for S Corps

One of the most significant tax considerations for S Corporations in California is the annual franchise tax. Unlike many other states that might exempt S Corps from this fee, California imposes a minimum franchise tax of $800 on all LLCs and corporations, including those electing S Corp status, regardless of their income or activity level. This tax is levied by the California Franchise Tax Board (FTB) and is due each year to maintain your business's good standing with the state. The $800 minimu

The S Corp is still required to file a California tax return, typically Form 100S, California Corporation Franchise or Income Tax Return. For tax years beginnin
