LLC Tax Basics
Single-Member LLC
By default, a single-member LLC is a “disregarded entity” — you report business income on Schedule C of your personal tax return. You pay:
| Tax | Rate | On What |
|---|---|---|
| Federal income tax | 10-37% | Net profit |
| Self-employment tax | 15.3% | Net profit (first $168,600 for SS at 12.4%, then 2.9% Medicare on all) |
| State income tax | 0-13.3% | Net profit (varies by state) |
S-Corp Tax Election
When your net profit exceeds ~$40,000-$50,000, electing S-Corp status can save thousands:
| Scenario | LLC (Default) | LLC with S-Corp Election |
|---|---|---|
| Net business income | $100,000 | $100,000 |
| Salary paid to yourself | N/A | $60,000 (reasonable) |
| SE tax (15.3%) | $14,130 | $9,180 (only on salary) |
| Distributions | N/A | $40,000 (no SE tax) |
| SE tax savings | $0 | $4,950 |
Operating Agreements
Every LLC should have an operating agreement, even with a single member:
| Section | What It Covers |
|---|---|
| Ownership | Member names, ownership percentages |
| Capital contributions | Initial investment by each member |
| Profit/loss distribution | How profits and losses are split |
| Management structure | Member-managed vs. manager-managed |
| Voting rights | How decisions are made |
| Adding/removing members | Process for ownership changes |
| Dissolution | How to close the LLC |
| Buy-sell provisions | What happens if a member wants out |
See Operating Agreement Guide.
LLC Types
| Type | What It Is | Best For |
|---|---|---|
| Single-member LLC | One owner | Freelancers, sole operators |
| Multi-member LLC | 2+ owners | Partnerships, joint ventures |
| Series LLC | Separate series within one LLC | Multiple rental properties |
| Professional LLC (PLLC) | For licensed professionals | Doctors, lawyers, CPAs |
See Single-Member LLC Guide, Multi-Member LLC Guide, Series LLC Explained, and Professional LLC (PLLC).
LLC Maintenance Checklist
| Task | Frequency | Why It Matters |
|---|---|---|
| File annual report | Yearly (most states) | Keeps LLC in good standing |
| Pay state annual fee | Yearly | Failure to pay = dissolution |
| Keep business/personal finances separate | Always | Protects liability shield |
| Update operating agreement | As needed | Reflects current reality |
| File LLC tax returns | Annually | Required by IRS |
| Renew business licenses | Varies | Required for operation |
| Maintain registered agent | Continuously | Required in all states |

The Bottom Line
If you’re earning money from a business, freelancing, or rental properties, forming an LLC is one of the cheapest and most effective ways to protect your personal assets. File in your home state (ignore the Delaware hype unless you’re a large company), draft a simple operating agreement, separate your finances, and file your annual reports on time. When your net profit hits $40K-$50K, talk to a CPA about an S-Corp tax election — the self-employment tax savings alone can be $3,000-$15,000 per year.
