## Key Entity Types and Their Tax Implications
| Entity Type | Ownership & Formality | Tax Treatment | Pros & Cons |
|---|---|---|---|
| **S-Corporation** | Up to 100 shareholders; strict formalities | Pass-through taxation; avoids double tax | **Pros**: lower self-employment tax on distributions; **Cons**: restricted ownership, payroll required |
| **C-Corporation** | Unlimited shareholders; multiple share classes | Taxed at corporate level + dividends taxed again | **Pros**: access to VC, benefits deductibility; **Cons**: double taxation, complex compliance |
| **LLC** | Flexible ownership; few formalities | Usually pass-through; can elect S or C treatment | **Pros**: liability protection; **Cons**: self-employment taxes, inconsistent by state |
| **Partnership** | Multiple members; formal agreement advisable | Pass-through; can use LP, GP, LLP | **Pros**: simple structure; **Cons**: personal liability (GP), complex allocations |
## Considerations Based on Goals
- **Funding and growth**: Planning to seek outside capital likely favors C-corp structure for easier investment.
- **Pass-through benefits**: S-corps, LLCs, partnerships allow individual owners to deduct business losses (subject to basis at risk limits).
- **Self-employment taxes**: S-corps allow separation of wages vs distributions; LLCs taxed as sole proprietorships pay SE tax on all earnings.
- **State level considerations**: Each state treats LLCs, S-corps differently — annual filings, fees, taxes.
## Compliance Requirements for Each Structure
- Maintain corporate formalities: meetings, minutes (S- and C-corps).
- Separate bank and accounting systems.
- File appropriate tax returns:
- C-corp: Form 1120
- S-corp: Form 1120-S
- LLC: typically Schedule C or K-1 via 1065
- For LLCs electing S status, file Form 2553 by due date.
## Example Scenarios
- **Startup raising VC**: Choose C-corp. Jane’s AI startup expects high growth and investor interest. Double taxation is acceptable against future exit return.
- **Small service business**: John runs design agency earning $200,000. Electing S-corp status allows him to take reasonable salary ($80,000) and distributions ($120,000), reducing payroll self-employment taxes.
- **Remote team across states**: An LLC taxed as partnership with multiple members, each respecting state tax registrations.
## Actionable Steps to Set Up Right
1. Draft ownership agreement or bylaws
2. Register with state; obtain EIN
3. Open separate bank accounts
4. Elect tax status (e.g., S-corp) if desired
5. Set up payroll systems if corporate structure
6. Keep records – payroll, distributions, meetings, expense logs
**Conclusion**: There isn’t a one-size-fits-all. The optimal entity depends on growth plans, tax savings, liability exposure. Consulting with a tax advisor and considering both present earnings and future goals is essential.
