As a cybersecurity LLC in California, your default tax structure is pass-through taxation, meaning profits are taxed at the individual owner level. You can elect to be taxed as an S-Corp to potentially reduce self-employment taxes. Choosing the right structure depends on your profitability and individual tax situation. This connects to our resource on setting up your California LLC, which covers the details. Consult with a tax professional and consider using Lovie to model different scenarios.
