Quick Answers
Common questions from
California founders
Do I owe California taxes if my startup has no revenue yet
Often yes. A C-Corporation generally files Form 1120 with the IRS each year regardless of activity, and a corporation or LLC doing business in California typically owes the $800 minimum franchise tax. Which filings apply depends on your entity type and where you operate, but zero revenue usually doesn't mean zero filings, and a missed filing can become a disclosable issue during fundraising due diligence.
Do I need a CPA, an accountant, or a bookkeeper?
They solve different problems. A bookkeeper keeps your records accurate month to month. An accountant or CPA handles tax filings, compliance, and the judgment calls, like R&D credits or entity structure, that carry real financial consequences. Our guides explain where each one fits, and our Find a CPA section helps you evaluate providers when you're ready for hands-on help.
Is MyCali.Accountant an accounting firm?
No. MyCali.Accountant is an independent editorial resource for California startup founders. We explain the rules, flag the risks, and help you understand your options. When you need professional help, we connect you with an accounting provider experienced with California startups, and that provider handles the actual engagement.
Which California cities do you cover?
Our guidance applies statewide, with dedicated local context for Los Angeles, San Francisco, San Diego, San Jose, Sacramento, and Riverside. The core California rules are the same everywhere; the startup ecosystems and local considerations differ, and the city pages cover those.
