Business Entity Comparison: A Plain-English, Myth-Busting Guide
Sole Prop, LLC, S-Corp, C-Corp, Partnership—what’s the real difference? This page compares them side-by-side, calls out the internet myths, and gives you the practical, defensible version your business can actually use.
Who This Is For (and Who It Isn’t)
- Established businesses (usually $1–10M+ revenue) deciding or revisiting entity choice
- Multi-owner, multi-entity groups wanting liability protection and tax efficiency
- Owners who value clean documentation and a defensible plan over TikTok “hacks”
Not a fit: brand-new side hustles looking only for “lowest tax now” without books or payroll. We’re built for seasoned businesses.
Second opinions welcome. If someone told you “just open an LLC for tax savings,” you’ll like this page.
At-a-Glance: Side-by-Side Comparison
Sole Proprietorship
- Liability: none; personal assets exposed.
- Tax: pass-through to Schedule C; subject to self-employment tax.
- Admin: minimal setup; easiest to start, but least protective.
LLC
- Liability: member liability shield (when respected).
- Tax: default pass-through (disregarded or partnership). Election to S- or C-Corp possible.
- Admin: moderate; operating agreement, state fees, annual report.
S-Corporation
- Liability: corporate shield for shareholders.
- Tax: pass-through; owner-employees must take reasonable compensation before distributions.
- Admin: payroll + corporate formalities; eligibility rules apply.
C-Corporation
- Liability: strong shield.
- Tax: entity-level corporate tax; potential double tax on dividends.
- Admin: highest compliance load; suits equity comp and retained-earning strategies.
Partnership
- Liability: depends on form (LLP/LLC shield possible).
- Tax: pass-through with capital/basis tracking and special allocations rules.
- Admin: partnership/operating agreement, K-1s, and state filings.
Viral Myths vs. Reality (TikTok/IG)
Myth: “Open an LLC to save money on taxes.”
Reality: An LLC is a legal wrapper for liability. By default it’s taxed as a pass-through, so income/loss flows to you and is taxed at your individual rates. Savings come from how you’re taxed (elections) and your facts—not from the LLC label itself.
Myth: “S-Corps don’t pay taxes / you can avoid payroll taxes.”
Reality: S-Corp owners who work in the business must take reasonable compensation. The IRS routinely reclassifies underpaid distributions as wages—adding payroll taxes and penalties. S-Corps can be efficient at the right profit levels, with salary set correctly.
Myth: “C-Corps are only for massive companies.”
Reality: C-Corps can make sense for equity compensation, investment, or retained-earnings strategies—even at modest scale. They add compliance and may create double tax on dividends, so choose based on goals and forecasts.
Myth: “Partnerships let you split income any way you want.”
Reality: Allocations must follow substantial economic effect and capital/basis. Flexibility is great—but it has to be backed by the agreement and the books.

FAQ (Plain English)
Does an LLC save taxes?
Not by itself. It’s a liability vehicle. Tax results depend on elections (disregarded, partnership, S-Corp, or C-Corp) and your facts.
How do S-Corp “salary vs. distributions” rules really work?
If you provide services, you must pay yourself reasonable compensation before taking distributions. Underpaying salary invites IRS reclassification and payroll taxes.
When does a C-Corp make sense for a small business?
When you need equity compensation, outside capital, or a retained-earnings plan—and you accept the added compliance/double-tax trade-offs.
Partnership allocations—how flexible are they?
They can be flexible, but must follow substantial economic effect, track capital/basis, and match the agreement.
Can I switch later (e.g., LLC to S-Corp)?
Often yes, via an S-election when it becomes advantageous. Plan around wages, state issues, and timing.
Do you charge for quick screens?
Short fit calls are usually complimentary—we’ll tell you fast if there’s a clean path or if another structure fits better.
