Tax Deep Dive
LLC Taxation
All profit "passes through" to your personal tax return. You pay:
- Income tax: At your personal rate (10-37%)
- Self-employment tax: 15.3% on ALL profit (Social Security + Medicare)
Example: LLC with $100,000 profit
- Self-employment tax: $15,300 (15.3% × $100,000)
- Income tax: $22,000 (estimated, 22% bracket)
- Total tax: ~$37,300
C-Corp Taxation
The corporation pays tax on profits, then you pay tax again on dividends:
- Corporate tax: 21% flat rate
- Dividend tax: 15-20% when you take profits out
Example: C-Corp with $100,000 profit, distributed as dividends
- Corporate tax: $21,000 (21% × $100,000)
- Remaining: $79,000
- Dividend tax: $11,850 (15% × $79,000)
- Total tax: ~$32,850
But if you reinvest profits (no dividends), you only pay $21,000 corporate tax.
S-Corp Taxation
Pass-through like LLC, BUT you split income into salary + distributions:
- Salary: Subject to payroll taxes (15.3% split between you and corp)
- Distributions: NO self-employment tax
Example: S-Corp with $100,000 profit, $60,000 salary + $40,000 distribution
- Payroll tax on salary: $9,180 (15.3% × $60,000)
- No payroll tax on distribution: $0
- Income tax (all): $22,000
- Total tax: ~$31,180
Savings vs LLC: ~$6,120 per year
Critical: The IRS requires "reasonable compensation." If you pay yourself $20,000 salary on $200,000 profit, they'll reclassify distributions as wages and hit you with back taxes + penalties.
When to Choose Each Structure
Choose LLC If:
- ✅ You're a solo founder or small team (2-5 people)
- ✅ You want maximum flexibility and minimum paperwork
- ✅ You're in real estate, consulting, or service businesses
- ✅ You don't plan to raise outside investment
- ✅ You want to reinvest most profits (pass-through doesn't help if you don't take money out)
- ✅ You might have foreign members or multiple classes of ownership
Choose C-Corp If:
- ✅ You're raising venture capital (VCs require C-Corp)
- ✅ You plan to go public or get acquired
- ✅ You want to offer stock options to employees (ISOs only work in C-Corps)
- ✅ You're reinvesting profits for growth (21% tax < personal rate + self-employment)
- ✅ You want to deduct 100% of health insurance premiums
- ✅ You'll have more than 100 shareholders or foreign investors
Choose S-Corp If:
- ✅ Your business earns $60,000+ in profit annually
- ✅ You want to save on self-employment taxes (salary + distribution strategy)
- ✅ You have 1-5 owners, all US citizens/residents
- ✅ You don't need to raise outside capital
- ✅ You can handle the payroll and compliance requirements
- ✅ You want pass-through taxation with corporate-style tax savings
The Decision Tree
START: Will you raise VC money?
├── YES → C-Corp (Delaware)
└── NO → Will you have 100+ shareholders?
├── YES → C-Corp
└── NO → Will any owners be non-US?
├── YES → LLC or C-Corp (S-Corp not allowed)
└── NO → Annual profit expected?
├── Under $60K → LLC (simplicity wins)
└── Over $60K → S-Corp (tax savings kick in)
Common Mistakes
1. Choosing C-Corp "Because It Sounds More Serious"
C-Corp structure costs $5,000-10,000+ annually in extra taxes and compliance if you're not raising money. Don't default to it for ego reasons.
2. S-Corp Without Payroll
You MUST run payroll to take advantage of S-Corp tax benefits. That means payroll software, quarterly filings, W-2s. If you're not ready for that complexity, stick with LLC.
3. LLC Taxed as S-Corp Without Understanding
You can elect S-Corp tax treatment for your LLC (best of both worlds). But you still need payroll and reasonable compensation. The entity type and tax classification are separate decisions.
4. Ignoring State Taxes
California charges $800 minimum franchise tax on all entities. New York City doesn't recognize S-Corps (taxed as C-Corp). States matter—factor them into your decision.
5. Waiting Too Long to Switch
If you'll need C-Corp in 2 years, switch now. Converting later triggers taxes, requires new contracts, and complicates cap tables. Investors prefer clean structures from the start.
State Considerations
Delaware: The Startup Standard
- Pros: Court of Chancery (business-focused), investor-friendly laws, no state income tax if you operate elsewhere
- Cons: $300+ annual franchise tax, registered agent fees, foreign qualification in your home state
- Best for: C-Corps raising outside capital
Your Home State: Simplicity Wins
- Pros: No foreign qualification, lower fees, local presence
- Cons: May have higher taxes or less favorable laws
- Best for: LLCs, S-Corps, local businesses
Nevada/Wyoming: The Tax Havens
- Pros: No state income tax, strong privacy protections
- Cons: If you operate elsewhere, you'll pay taxes there anyway; added complexity
- Best for: Specific asset protection strategies (consult a lawyer)

Conversion: Can You Change Later?
LLC → C-Corp
Possible: Yes. Common when raising Series A.
Cost: Legal $3,000-10,000, potential tax triggers, new EIN, contract assignments
LLC → S-Corp
Possible: Yes, via tax election (Form 2553)
Cost: Free (just IRS filing), but now you need payroll
C-Corp → LLC
Possible: Technically yes, but rarely worth it
Cost: High tax implications, complicated unwind—avoid if possible
S-Corp → C-Corp
Possible: Yes (revoking S election)
Cost: Generally tax-free, but you lose pass-through benefits
