What is an LLC?

A Limited Liability Company (LLC) is a flexible business structure that combines the liability protection of a corporation with the tax flexibility of a partnership. LLCs are the most popular business structure for small businesses in 2026.

LLC Tax Flexibility

LLCs can choose how they're taxed:

This flexibility makes LLCs ideal for businesses that may evolve. See our LLC tax filing deadlines guide for specific dates.

When to Choose LLC

What is an S-Corp?

An S-Corporation isn't a business entity—it's a tax election available to LLCs and corporations. S-Corp status provides pass-through taxation while allowing owners to reduce self-employment taxes through salary/distribution splits.

S-Corp Tax Savings Example

Consider a business with $150,000 profit:

Without S-Corp (LLC default):

  • Self-employment tax (15.3%): $22,950
  • Income tax (estimated 24%): $36,000
  • Total tax: $58,950

With S-Corp election:

  • Reasonable salary: $80,000
  • Distribution: $70,000
  • Payroll tax on salary: $12,240
  • Income tax (estimated): $36,000
  • Total tax: $48,240

Annual savings: $10,710

What is a C-Corp?

A C-Corporation is a separate legal entity that pays corporate income tax. While subject to "double taxation" (corporate tax + dividends tax), C-Corps offer significant advantages for raising capital and planning for growth or exit.

C-Corp Tax Structure

While double taxation sounds bad, C-Corps can be more tax-efficient for businesses that:

State Considerations

While federal tax rules are uniform, state rules vary significantly:

States with No Corporate Income Tax

States with High LLC/C-Corp Costs

Our entity selection checklist helps you evaluate state-specific factors.

Common Mistakes to Avoid

1. Choosing Based on Setup Cost Alone

A $500 LLC that costs you $10K extra in taxes isn't a bargain. Consider total cost of ownership.

2. Ignoring S-Corp When Profitable

Many LLC owners leave $5K-15K on the table annually by not electing S-Corp status.

3. Choosing C-Corp Too Early

C-Corp formalities and double taxation can burden early-stage businesses. Convert when you actually raise capital.

4. Not Considering State Costs

California's $800 minimum tax applies whether you make money or not. Choose your formation state strategically.

5. Mixing Personal and Business Assets

Regardless of entity type, maintain separate accounts and records. Commingling destroys liability protection.

Frequently Asked Questions

Can I change my entity type later?

Yes. LLCs can elect S-Corp or C-Corp taxation. Converting between entity types is possible but may have tax consequences. It's easier to start flexible (LLC) than to unwind a C-Corp.

Do I need a lawyer to form an entity?

Not necessarily. Simple LLCs can be filed online in most states for $50-200. However, C-Corps with complex stock structures or multi-state operations benefit from legal guidance.

What's the self-employment tax rate for 2026?

15.3% on first $168,600 of income (Social Security 12.4% + Medicare 2.9%). Additional 0.9% Medicare tax applies above certain thresholds. S-Corp distributions avoid these taxes.

Can a single-person business be an S-Corp?

Yes. Single-member LLCs can elect S-Corp status. You'll need to run payroll and take a reasonable salary, but distributions are exempt from self-employment tax.

Which entity is best for real estate?

LLCs are typically preferred for real estate because they offer liability protection, pass-through taxation, and flexibility in profit distribution. S-Corps can create complications with property appreciation.
