LLC vs. S-Corp: Which Business Structure Is Right for You?
Choosing between an LLC and an S-Corp is one of the most impactful decisions a business owner will make. Both offer liability protection and pass-through taxation, but they differ significantly in self-employment tax treatment, management flexibility, ownership restrictions, and compliance requirements. This guide provides a detailed comparison to help you understand which structure best serves your business goals.
Understanding LLCs and S-Corps
Limited Liability Company (LLC)
An LLC is a state-law entity that provides its owners (called members) with limited liability protection while offering pass-through taxation and maximum operational flexibility. An LLC can be taxed as a sole proprietorship, partnership, C-Corporation, or S-Corporation, making it the most versatile entity type available. Florida LLCs are governed by the Florida Revised Limited Liability Company Act.
S-Corporation
An S-Corp is not a distinct entity type under state law. It is a tax election made with the IRS (Form 2553) that allows a qualifying corporation or LLC to pass income through to shareholders while enabling the split of income between salary (subject to FICA) and distributions (not subject to FICA). S-Corps are governed by Subchapter S of the Internal Revenue Code and must meet specific eligibility requirements.
Detailed Comparison
The following comparison examines six critical dimensions where LLCs and S-Corps differ most significantly.
Formation
Formed by filing Articles of Organization with the Florida Division of Corporations. Requires an operating agreement to govern member relations, though not mandated by statute. Filing fee is $125. Relatively simple formation process with minimal formalities.
Formed as a corporation by filing Articles of Incorporation with the state, then electing S-Corp status by filing IRS Form 2553. Must be filed within 75 days of incorporation or by March 15 for existing entities. Filing fee is $70 plus the cost of preparing corporate documents.
Taxation
Default pass-through taxation. Single-member LLCs are treated as disregarded entities (reported on Schedule C). Multi-member LLCs are taxed as partnerships (Form 1065). Income passes through to members' personal returns. An LLC may also elect to be taxed as a corporation or S-Corp.
Pass-through taxation with a critical distinction: the owner-employee must receive a reasonable salary subject to FICA taxes, but remaining profits distributed as shareholder distributions are not subject to self-employment tax. This split can produce significant tax savings for profitable businesses.
Self-Employment Tax
All net earnings of an LLC member who actively participates in the business are generally subject to self-employment tax (currently 15.3% on the first $168,600 of combined wages and self-employment income, and 2.9% Medicare tax above that amount, plus the 0.9% Additional Medicare Tax for high earners).
Only the reasonable salary paid to the shareholder-employee is subject to FICA taxes. Distributions of remaining profits are not subject to self-employment or FICA taxes. This can result in savings of thousands of dollars annually, depending on the owner's income level and the reasonableness of their salary.
Management Structure
Maximum flexibility. Can be member-managed (all members participate in decisions) or manager-managed (designated managers handle operations). No requirement for officers, directors, or annual meetings. The operating agreement defines roles, responsibilities, and decision-making authority.
Requires a formal corporate structure with a board of directors, officers (president, secretary, treasurer), and documented corporate minutes. Annual shareholder and director meetings must be held and recorded. More administrative overhead than an LLC.
Ownership Restrictions
No restrictions on the number or type of members. Members can be individuals, corporations, other LLCs, partnerships, trusts, or foreign nationals. No limit on the number of members. Multiple classes of membership interests are permitted with flexible profit-sharing arrangements.
Limited to 100 shareholders. Shareholders must be U.S. citizens or resident aliens, certain trusts, or estates. No foreign ownership. Only one class of stock is permitted (though voting and non-voting shares are allowed). These restrictions can limit future investment and growth options.
Compliance Requirements
Florida requires annual reports (filed with the Division of Corporations by May 1, $138.75 fee). No requirement for formal meetings, minutes, or resolutions. Relatively light ongoing compliance burden. Must maintain registered agent and updated records.
Same state annual report requirements as any Florida corporation. Additionally requires corporate formalities: annual meetings, meeting minutes, corporate resolutions, stock certificates, and stock transfer ledger. Must maintain reasonable compensation documentation for the IRS. Greater administrative and record-keeping burden.

Tax Implications That Require Expert Navigation
The LLC vs. S-Corp decision is fundamentally a tax planning decision. While both structures offer pass-through taxation, the self-employment tax savings from an S-Corp election can be substantial, but only when the reasonable compensation requirement is properly satisfied. The IRS scrutinizes S-Corp shareholder salaries, and setting compensation too low invites audit risk and potential reclassification of distributions as wages with back taxes, penalties, and interest.
Peter P. Lindley is uniquely qualified to guide this decision because he is both an attorney and an active CPA with Big 4 experience at KPMG Peat Marwick and Ernst & Young. He analyzes your specific income levels, industry benchmarks, growth trajectory, and ownership plans to determine not only which structure is optimal today but also when it might make sense to convert from one to the other as your business evolves. Many business owners transition from an LLC to an S-Corp election as their income grows, and the timing and mechanics of that conversion require precise legal and tax execution.
Unlike attorneys who must refer tax questions to a separate CPA, or CPAs who cannot provide legal advice on entity structuring and governance, Peter delivers integrated counsel in a single relationship. This means your entity structure, operating agreement, tax elections, and compensation strategy are all coordinated from a single perspective, eliminating the conflicting advice and communication gaps that plague business owners who rely on multiple professionals.
