As a construction LLC in California, your tax structure depends on your elections. By default, a single-member LLC is taxed as a sole proprietorship, while a multi-member LLC is taxed as a partnership. You can also elect to be taxed as an S-Corp or C-Corp for potentially different tax advantages. This connects to our resource on the California LLC filing process, which covers the details. Understanding these options is key to optimizing your tax burden.
Single-member LLCs pay self-employment tax (15.3%) plus income tax on all net profits, reported on Schedule C of the owner's personal tax return.
