Default Classification.
By default, the IRS treats a single-member LLC as a sole proprietorship, and a multi-member LLC as a partnership.
Entity Classification Election
Use Form 8832 to elect for your LLC or partnership to be taxed as a corporation (C-Corp).
S-Corporation Election.
Use Form 2553 to elect S-Corp status — allowing income, losses, and credits to pass through to shareholders, avoiding double taxation.
