LLCs, S-Corps, and C-Corps

LLCs, S-Corps, and C-Corps

Three entity types dominate American business formation: the Limited Liability Company (LLC), the S-Corporation, and the C-Corporation. Each exists for a reason. Each solves a different problem. Choosing wrong does not just cost you money in taxes or compliance overhead. It can limit your ability to raise capital, bring on partners, or exit the investment. The LLC is the workhorse of real estate investing. More than 70% of new business filings in the U.S. are LLCs. The S-Corp is the tool of choice for active businesses generating meaningful profit. The C-Corp is built for scale, outside investors, and eventual IPO or acquisition. Understanding when to use each is as important as understanding how they work.

The LLC: Formation and Structure

An LLC is formed by filing Articles of Organization with your state. Filing fees range from $50 (Kentucky, Mississippi) to $500 (Massachusetts). Most states fall in the $100-200 range. Some states charge annual fees: California's infamous $800 minimum franchise tax hits every LLC regardless of income. Delaware charges $300/year. Wyoming and New Mexico charge nothing annually. After filing, you need an Operating Agreement. This is the internal governance document. For a single-member LLC, it documents your ownership and management procedures. For multi-member LLCs, it covers capital contributions, profit/loss allocation, voting rights, transfer restrictions, and what happens when a member wants out or dies. Banks will not open a business account without one. An Operating Agreement is not legally required in every state, but operating without one is reckless. Single-member vs. multi-member affects taxation. A single-member LLC is a "disregarded entity" for federal tax purposes. It does not file its own return. Income and expenses go on Schedule C (active business) or Schedule E (rental income) of your personal 1040. A multi-member LLC files Form 1065 as a partnership and issues K-1s to each member.

• Formation: Articles of Organization + state filing fee ($50-500).
• Governance: Operating Agreement defines ownership, management, distributions, exits.
• Banking: Separate EIN from IRS (free, takes 5 minutes online). Open a dedicated business account.
• Annual compliance: State annual report ($0-300/year depending on state). Some states require registered agent ($50-150/year).
• Series LLC (available in ~20 states): One parent LLC with multiple "series," each holding a separate property. Each series has its own liability shield. Saves on filing fees vs. forming separate LLCs for each property.

S-Corp: The Self-Employment Tax Strategy

An S-Corp is not a separate entity type. It is a tax election. You form an LLC (or a corporation) and then file Form 2553 with the IRS to elect S-Corporation tax treatment. The reason: self-employment tax savings. Self-employment tax (Social Security + Medicare) is 15.3% on the first $168,600 of net self-employment income (2024), and 2.9% on income above that. For an LLC without the S-Corp election, all net profit is subject to self-employment tax. With the S-Corp election, you split income into two buckets: salary (subject to payroll taxes) and distributions (not subject to payroll taxes). The IRS requires you pay yourself a "reasonable salary" for the work you perform. But profit above that salary is distributed as a dividend, free of the 15.3% self-employment tax. Example: Your property management business nets $150,000. As a standard LLC, you pay $19,800 in self-employment tax (15.3% on $129,600 + 2.9% on $20,400 = $19,831 + $592 = $20,423). As an S-Corp, you pay yourself a $70,000 salary. Self-employment tax on the salary: $10,710. The remaining $80,000 is distributed without self-employment tax. Total savings: approximately $9,700 per year. The break-even point is roughly $40,000-50,000 in net profit. Below that, the added cost of payroll processing ($500-2,000/year), additional tax filings, and compliance overhead eats the savings.

C-Corp: Built for Scale and Outside Capital

C-Corporations are the structure of venture-backed startups, publicly traded companies, and any business planning to raise capital from institutional investors. The double taxation is a real cost, but C-Corps offer capabilities that pass-through entities cannot match. C-Corps can have unlimited shareholders of any type: individuals, other corporations, foreign nationals, trusts, and institutional funds. S-Corps are limited to 100 shareholders, all of whom must be U.S. citizens or residents, and cannot include other corporations or partnerships. C-Corps can issue multiple classes of stock. Preferred shares with liquidation preferences, common shares with voting rights, restricted stock for employees. This flexibility is essential for venture capital structures where investors demand preferred returns and protective provisions. The tax picture is not always as bad as the headline suggests. C-Corps pay a flat 21% federal rate. Founders who reinvest profits into growth rather than distributing them avoid the second layer of tax entirely. Qualified Small Business Stock (QSBS) under Section 1202 allows founders and early investors to exclude up to $10 million in capital gains (or 10x their basis) when selling C-Corp stock held for 5+ years. For a founder selling a company for $15 million, the QSBS exclusion can save $3 million or more in capital gains tax.

• Unlimited shareholders of any type (individuals, entities, foreign nationals).
• Multiple stock classes for complex investor structures.
• 21% flat corporate tax rate. Second layer only on distributions.
• QSBS exclusion: up to $10M in tax-free capital gains on stock held 5+ years.
• Required: board of directors, corporate minutes, annual meetings, formal governance.

When to Use Each Entity

The decision framework is straightforward once you identify your primary activity, expected income level, and capital structure needs. Most real estate investors will use LLCs for property holding and possibly an S-Corp election for an active management or brokerage business. C-Corps are rare in real estate unless you are building a technology platform or raising venture capital.

A Real Investor's Entity Stack

Dana owns six rental properties and operates a property management company serving 40 units (her own plus clients). Her entity structure:

1. Birch Holdings LLC: Holds three single-family rentals. Taxed as a disregarded entity. Net rental income flows to Dana's Schedule E. Annual cost: $150 state filing + $0 federal filing.

2. Maple Properties LLC: Holds a triplex and two duplexes. Multi-member LLC (Dana owns 70%, her brother owns 30%). Files Form 1065 partnership return. Each gets a K-1. Annual cost: $150 state filing + $800 CPA for partnership return.

3. Dana Taylor Property Management LLC (S-Corp election): Her active management business collecting $180,000/year in management fees. She pays herself a $85,000 salary and takes $95,000 in distributions. Self-employment tax savings: approximately $14,500/year. Annual cost: $150 state filing + $2,400 payroll service + $1,200 CPA for S-Corp return.

Total annual entity maintenance cost: approximately $4,850. Total annual tax savings from S-Corp election alone: approximately $14,500. Net benefit before considering liability protection: roughly $9,650 per year.

Start Simple, Add Complexity When It Pays For Itself

Do not form five entities before you own your first property. Start with one LLC for your first rental. Add entities as your portfolio grows and the math justifies the overhead. The right time to consider an S-Corp election is when your active business income consistently exceeds $50,000 per year and the self-employment tax savings exceed the cost of payroll and additional tax preparation. The right time to consider separate LLCs per property is when any single property's value or risk profile is high enough that you would not want a claim against it to endanger your other holdings. For most investors, that threshold is around 4-6 properties or $1 million in total portfolio value.
