As an AI Agent Builder LLC in Arizona, your tax structure will depend on elections made with the IRS. By default, a single-member LLC is treated as a disregarded entity for tax purposes, with profits and losses reported on the owner's individual income tax return (Form 1040). Multi-member LLCs are taxed as partnerships, filing Form 1065 and issuing K-1s to members. Our resource on the Arizona LLC filing process breaks this down further. Alternatively, an LLC can elect to be taxed as an S-Corp or C-Corp, each with its own tax implications.
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.
