|---|---|---|---|
| Disregarded entity | Single-member LLC | Schedule C (1040) | 15.3% on net earnings |
| Partnership | Multi-member LLC | Form 1065 + K-1s | On each member's share |
| S-corporation | By election (Form 2553) | Form 1120S | Only on salary portion |
| C-corporation | By election (Form 8832) | Form 1120 | Not applicable (different structure) |
Self-Employment Tax
The primary federal tax burden for profitable Indiana LLC owners:
- Rate: 15.3% (12.4% Social Security on first $168,600 + 2.9% Medicare on all earnings)
- Additional Medicare: 0.9% on earnings over $200,000 (single) / $250,000 (MFJ)
- Deduction: 50% of SE tax is deductible above-the-line
This is why S-corp election matters once income exceeds $50,000-$60,000. See our LLC vs S-Corp comparison.

FAQ
Do I file a separate federal return for my LLC?
Single-member: No — report on Schedule C of your personal 1040. Multi-member: Yes — file Form 1065 (informational). Both still pass income to personal returns for tax payment.
When should I consider S-corp election?
When net income consistently exceeds $50,000-$60,000 and the SE tax savings exceed the costs of payroll processing + additional tax prep.
Can I deduct my Indiana state taxes on my federal return?
Yes, subject to the $10,000 SALT cap. Your Indiana income tax (2.95% state + county rate) counts toward this cap along with property taxes.
