LLC vs S-Corp vs C-Corp: Complete 2026 Comparison

Choosing the wrong business structure can cost you tens of thousands in taxes, expose your personal assets to liability, or block your fundraising ability. Here's the definitive side-by-side comparison for 2026.

Quick Answer: Most small businesses should start as LLCs. S-Corps make sense at $60K+ profit. C-Corps are for VC-backed startups planning to go public.

Deep Dive: LLC (Limited Liability Company)

The LLC is the most flexible structure—like a Swiss Army knife for businesses.

How LLCs Work

LLCs combine the liability protection of corporations with the tax simplicity of sole proprietorships:

LLC Tax Example

Scenario: $100,000 profit, single-member LLC

Tax Type Calculation Amount
Self-employment tax $100,000 × 15.3% $15,300
Income tax (22% bracket) $100,000 × 22% $22,000
Total tax $37,300

When to Choose LLC

Deep Dive: S-Corp (S Corporation)

S-Corps are LLCs or C-Corps that elect special tax treatment. The magic: you only pay self-employment tax on your salary, not your profit distributions.

How S-Corps Work

The S-Corp election creates two income streams:

This split can save you thousands—but you must pay yourself a "reasonable salary" or the IRS will reclassify everything.

S-Corp Tax Example

Scenario: $100,000 profit, $60K salary, $40K distributions

Tax Type Calculation Amount
Payroll tax (salary) $60,000 × 15.3% $9,180
Income tax (total) $100,000 × 22% $22,000
Total tax $31,180
Savings vs LLC $6,120
Reasonable Salary Warning: If you pay yourself $20K salary on $100K profit, the IRS will audit you. Reasonable salary = what you'd pay someone else to do your job. In this example, $50-70K would be defensible for a skilled consultant.

S-Corp Break-Even Analysis

Running payroll costs money. Here's when S-Corp makes sense:

Profit LLC Tax S-Corp Tax Net Savings Worth It?
$40,000 $14,920 $12,480 $2,440 Borderline
$60,000 $22,380 $18,720 $3,660 ✅ Yes
$100,000 $37,300 $31,180 $6,120 ✅ Definitely
$200,000 $74,600 $62,360 $12,240 ✅ Absolutely

Assumes reasonable salary = 60% of profit, 22% income tax bracket, $1,200/year payroll costs

Deep Dive: C-Corp

C-Corps are separate tax entities—the business pays taxes, then you pay taxes again on dividends. But they're the only structure VCs will invest in.

How C-Corps Work

C-Corp Tax Example

Scenario: $100,000 profit, all distributed as dividends

Tax Type Calculation Amount
Corporate income tax $100,000 × 21% $21,000
Dividend tax (15%) $79,000 × 15% $11,850
Total tax $32,850

This is worse than both LLC ($37,300) and S-Corp ($31,180)... for small businesses. But C-Corps have a secret weapon.

The C-Corp Advantage: Reinvestment

C-Corps only get taxed on profits that aren't reinvested. If you keep all $100K in the business:

Structure Tax on $100K Cash Available to Reinvest
LLC $37,300 $62,700
S-Corp $31,180 $68,820
C-Corp (reinvested) $0 $100,000

For high-growth companies reinvesting everything, C-Corps can actually be cheaper.

When to Choose C-Corp

VC Requirement: If you're pitching VCs, they will almost certainly require you to be a Delaware C-Corp before investing. It's not optional.

Decision Framework

Choose LLC If:

Choose S-Corp If:

Choose C-Corp If:

Can You Change Later?

Yes, but with caveats:

Strategy: Start as LLC. If profit crosses $60K, elect S-Corp status retroactively (IRS allows same-year elections). Only go C-Corp when VCs require it.

Common Mistakes

  1. Choosing C-Corp too early: VC dreams don't justify double taxation on $50K profit
  2. S-Corp with low profit: Payroll costs eat the savings under $40K profit
  3. Unreasonable salary: $20K salary on $150K profit = audit bait
  4. Ignoring state taxes: California's $800 franchise tax applies to all three
  5. Skipping operating agreement: 50/50 LLC without agreement = deadlock waiting to happen
  6. Foreign owner in S-Corp: Instant disqualification, back taxes owed

State-Specific Considerations

Your state matters almost as much as federal rules:

Cost Comparison

Cost Category LLC S-Corp C-Corp
Formation $50-500 $50-500 $50-500
Annual report $0-300 $0-300 $0-300
Payroll service $0 $300-1,200 $300-1,200
Registered agent $0-300 $0-300 $0-300
Accounting/tax prep $500-1,500 $1,000-3,000 $1,500-5,000
Total annual $500-2,300 $1,350-5,800 $1,850-7,300

The Bottom Line

For 90% of small businesses in 2026:

  1. Start as LLC — simplest, cheapest, most flexible
  2. Elect S-Corp when profit crosses $60K and savings > $3K/year
  3. Convert to C-Corp only when VCs require it (and they will)
