Should I form my Plumbers LLC in California or a different state?

For most plumbers operating in California, forming locally avoids foreign qualification costs and simplifies compliance. Delaware, Wyoming, or Nevada formation only makes sense if you genuinely operate there. Running a California-based business as a Wyoming LLC typically costs more (both Wyoming fees + California foreign qualification) while providing no real tax benefit.

What type of LLC tax structure is best for a Plumbers in California?

By default, a single-member LLC is taxed as a disregarded entity (Schedule C); multi-member as a partnership. Once net profit exceeds ~$80K, an S-Corp election typically saves significantly on self-employment tax. Note that California's franchise tax ($800/yr minimum (even with $0 revenue)) applies regardless of federal classification.
