How to Choose a Business Structure

The structure you pick determines your taxes, your paperwork, your ability to raise money, and how protected you are from lawsuits. It's the highest-leverage decision you'll make at formation — and most people can decide in about five minutes using the decision tree below.

The structures at a glance

Step 1 — Start with "is this for a business or a mission?"

• If you're building a mission-driven organization where nobody profits → go nonprofit.
• If you're a licensed professional (doctor, lawyer, CPA, architect, therapist) and your state requires it → PLLC.
• Otherwise → continue to the business decision tree.

Step 2 — Are you planning to raise VC money?

• Yes → C-Corp, almost always in Delaware. Investors require it: preferred stock, option pools, and corporate governance.
• No → continue.

Step 3 — Are you on a restricted immigration status?

If you're an H-1B, L-1, EAD, or ITIN holder, one rule dominates the decision:

• S-Corp is not available to you — shareholders must be US citizens or green card holders.
• LLC and C-Corp are both open to most visa/ITIN holders.

This single eligibility rule determines more immigrant-founder decisions than any tax math. See our visa guides for details.

Step 4 — Is your net profit going to be ~$80k+?

• Yes → consider an LLC with an S-Corp election. You save 15.3% self-employment tax on profit above your reasonable salary.
• No → a plain LLC is almost always right. The S-Corp's payroll overhead eats small savings.

Step 5 — Who's involved and what are you doing?

• Solo, services, online sales → Single-member LLC.
• Partners (even family) → Multi-member LLC with an Operating Agreement.
• Multiple real estate properties, each needing separate liability → Series LLC (if your state allows it).

The default answer

Here's the honest shortcut: for 80% of small businesses, the answer is a single-member or multi-member LLC. It protects you, taxes simply, costs little to run, and can elect S-Corp later — no conversion needed.

The structures that need a "real reason":

• C-Corp — needs a VC or IPO reason, or foreign shareholders.
• PLLC — needs a licensing requirement.
• Nonprofit — needs a genuine charitable mission.
• Series LLC — needs multiple properties/projects with separate liability needs.

Red flags to watch for

• "S-Corp to save on taxes" from day one — fine if you're already profitable; wasteful if not.
• Forming a Delaware LLC when you'll never raise money — you're paying for foreign qualification for no reason.
• A "one-owner" multi-member LLC — ownership percentages and an Operating Agreement keep the IRS happy.
• Avoiding a structure entirely — operating as a sole proprietorship gives you zero liability protection.

Common questions

Can I change structures later? Yes. LLC → S-Corp is a tax form (2553). LLC → C-Corp is a conversion or reincorporation. It's easier to start simpler and upgrade than to downgrade.

What if I'm in a high-risk business? Construction, restaurants, manufacturing, and anything with physical injury risk benefit most from an LLC or corporation — the liability shield is the point.

Do I need an Operating Agreement? Yes — especially multi-member. See our Operating Agreement guide.

Does structure affect my ability to hire? Only your tax registration (EIN, state payroll) matters for hiring. Structure matters for equity and taxes, not headcount.
