What is a Limited Liability Company?
<p>A Limited Liability Company (LLC) is a legal US business entity profile that blends the simple tax pass-through structure of a partnership or sole proprietorship with the structural protection of a corporate shield. Owners of an LLC are legally referred to as members.</p>
Tax Structure Deep Dive
<p>By default, the IRS treats single-member LLCs as disregarded entities and multi-member LLCs as partnerships. This means profits and losses flow directly to your personal tax return (Form 1040, Schedule C). However, an LLC has the unique flexibility to elect corporate tax treatment (S-Corp or C-Corp classification) via IRS Form 2553 if it yields strategic tax savings.</p>
