Limited Liability Company (LLC) owners generally need to file their personal tax returns alongside Form 1065 if their LLC is classified as a partnership for tax purposes. Form 1065 serves to report the income, gains, losses, deductions, and credits of the partnership. Each member of the partnership will then receive a Schedule K-1, which outlines their share of the LLC's income and deductions, allowing them to accurately report this information on their individual tax returns.

If the LLC is taxed as a corporation, the filing requirements differ. In such cases, the LLC would file Form 1120 or Form 1120-S, depending on whether it is treated as a C corporation or an S corporation, respectively. Owners should be aware of the estimated tax due dates 2024, as these deadlines are critical for maintaining compliance and avoiding penalties.
