As an e-commerce LLC in California, your tax structure depends on your elections. By default, a single-member LLC is treated as a disregarded entity for tax purposes, with profits and losses reported on your personal income tax return (Form 1040). A multi-member LLC is taxed as a partnership, filing Form 1065 and issuing K-1s to members. For more details, see our guide on [LLC registration in California](https://www.lovie.co/formation/resources/llc-formation/agency-california). Alternatively, you can elect to have your LLC taxed as an S-Corp or C-Corp, each with its own set of tax implications. S-Corp election (Form 2553) can potentially reduce self-employment taxes, while C-Corp status subjects your business to corporate income tax.
