The Three Main Structures: Overview
Most freelancers start as sole proprietors by default — no paperwork, no fees, just filing Schedule C at tax time. But as income grows, two alternatives become attractive: forming an LLC for liability protection, or electing S-Corp status to reduce self-employment taxes.
The key insight: these are separate decisions. Forming an LLC is a state-law choice about liability. S-Corp election is a federal-tax choice about how income is characterized. You can do one without the other, or both together.
| Structure | SE Tax Treatment | Liability Protection | Complexity | Annual Cost |
|---|---|---|---|---|
| Sole Proprietor | 15.3% on net SE income | None | Very simple | $0 |
| Single-Member LLC | Same as sole prop (disregarded) | Yes (personal assets protected) | Low | $50–$800/year |
| LLC + S-Corp Election | SE tax only on W-2 salary portion | Yes | High (payroll required) | $2,000–$5,000/year |
Sole Proprietor: Default for Most Freelancers
Operating as a sole proprietor requires no paperwork, no state filing, and no separate tax return. You file Schedule C with your Form 1040 and pay self-employment tax on 92.35% of your net profit at 15.3% (12.4% Social Security + 2.9% Medicare).
Sole proprietorship makes sense when:
- Annual net SE income is below $60,000–$80,000
- You have minimal liability risk (low-stakes work, no client assets at risk)
- You're just starting out and want to minimize overhead
- You prefer the simplicity of one tax return
The downside: no liability protection. If a client sues you, your personal assets (bank accounts, car, savings) are exposed. For many freelancers, professional liability insurance addresses this risk without the complexity of an LLC.
LLC: Liability Protection Without Tax Change
An LLC (Limited Liability Company) separates your personal assets from your business. If your freelance business is sued, the LLC creates a legal barrier protecting your personal wealth — in theory. (Courts can "pierce the corporate veil" if you don't maintain separation between personal and business finances.)
A single-member LLC is a "disregarded entity" for federal tax purposes — the IRS ignores the LLC and taxes you as a sole proprietor. You still file Schedule C and pay the same SE taxes. The LLC changes nothing about federal taxes.
LLC formation costs vary by state: as low as $50 (Kentucky, Mississippi) to $520 (Massachusetts) plus ongoing annual report fees. California charges an $800 minimum annual franchise tax, making LLC costs particularly high there at low income levels.
S-Corp: SE Tax Savings for High Earners
An S-Corp changes how income is characterized for federal tax purposes. Instead of all net profit being subject to SE tax, you split income between:
- W-2 salary: Subject to payroll taxes (Social Security + Medicare) — equivalent to SE tax
- Distributions: Not subject to payroll taxes or SE tax — pure savings
The IRS requires you to pay yourself a "reasonable salary" for the services you perform. You can't set your salary to $1 to avoid all payroll taxes — that's an audit flag. But a reasonable salary of $60,000–$80,000 on $150,000 in profit means $70,000–$90,000 flows out as distributions, entirely avoiding SE tax.
To elect S-Corp status, you file Form 2553 with the IRS. You must file it by March 15 for it to take effect in the current tax year. Most freelancers form an LLC first, then elect S-Corp treatment on that LLC by filing Form 2553.
The S-Corp Math: How Much Does It Actually Save?
The savings come from the difference in SE tax treatment on the distribution portion. Here's a concrete example with $150,000 in net freelance profit:
| Scenario | SE Tax Paid | Total Tax Cost |
|---|---|---|
| Sole Proprietor (all $150K as SE income) | ~$20,900 | ~$20,900 |
| S-Corp: $70K salary + $80K distribution | ~$9,750 (on salary only) | ~$9,750 + $2,500 admin = $12,250 |
| Annual Savings | ~$8,650 |
Note that SS tax (12.4%) only applies up to the SS wage base ($176,100 in 2026). Above that threshold, only the 2.9% Medicare portion applies — so SE tax savings from S-Corp distributions are smaller for income above $176,100 per year.
When Should You Incorporate? Income Thresholds
The general rule of thumb used by tax professionals:
| Annual Net SE Income | Recommended Structure | Reason |
|---|---|---|
| Under $40,000 | Sole Proprietor | S-Corp costs exceed savings |
| $40,000–$80,000 | Sole Prop or LLC (no S-Corp) | Liability protection, but S-Corp not yet worthwhile |
| $80,000–$100,000 | LLC + Consider S-Corp | Break-even zone — run the numbers carefully |
| $100,000–$250,000 | LLC + S-Corp Election | Clear SE tax savings exceed costs |
| Over $250,000 | LLC + S-Corp (CPA required) | Significant savings; complexity increases |
These thresholds vary by state (some have high LLC fees or additional taxes that shift the math), your industry, and your risk profile for liability. Always run the numbers for your specific situation before making a structural change.
The Real Costs of Incorporating
The tax savings calculations above only make sense net of the real costs of maintaining a corporate structure:
LLC formation costs (one-time + annual)
- State filing fee: $50–$520 depending on state
- Annual report / franchise tax: $0–$800/year (California: $800 minimum)
- Registered agent: $0–$150/year if using a service
Additional S-Corp costs (annual)
- Payroll software or service: $500–$2,000/year
- Additional CPA fees for S-Corp return (Form 1120-S): $1,000–$3,000/year more than sole prop
- Bookkeeping to maintain separation: $0 (DIY) to $2,000/year
How to Set Up an LLC or S-Corp
- Choose your state: File in the state where you primarily work, not necessarily Delaware or Wyoming (the "tax haven" states offer minimal benefit for small freelancers and add complexity)
- File Articles of Organization: With your state's Secretary of State office — can usually be done online
- Get an EIN: Required for LLCs and all corporations — see our EIN guide
- Open a business bank account: Essential to maintain the LLC's liability protection
- If electing S-Corp: File Form 2553 with the IRS by March 15 for current-year effect, set up payroll, and file quarterly payroll taxes
- File annual state report: Most states require an annual or biennial filing to maintain the LLC in good standing

Frequently Asked Questions
When should a freelancer incorporate?
Freelancers generally benefit from S-Corp election once net self-employment income reaches $80,000–$100,000 annually. Below that, the administrative costs (payroll, CPA, state fees) often exceed the SE tax savings. An LLC for liability protection can make sense at lower income levels — even $40,000–$60,000 — without changing your tax treatment.
Does forming an LLC reduce self-employment taxes?
No — not by itself. A single-member LLC is a "disregarded entity" that pays identical federal self-employment taxes as a sole proprietor. To reduce SE taxes through your business structure, you need to elect S-Corp taxation by filing Form 2553 — which requires running payroll. The LLC alone only changes your liability protection, not your tax treatment.
How much does an S-Corp save in taxes for freelancers?
At $150,000 net profit with a $70,000 reasonable salary, the SE tax savings can be $8,000–$11,000 annually, minus $2,000–$3,500 in additional accounting and payroll costs — for a net benefit of roughly $5,000–$8,000. Savings scale with income; at $200,000, net savings are often $12,000–$18,000 after costs.
What are the costs of incorporating as a freelancer?
LLC formation: $50–$520 state filing fee, $0–$800 annual franchise tax. S-Corp ongoing costs: $500–$2,000/year payroll software, $1,000–$3,000/year additional CPA fees for Form 1120-S and payroll tax returns. Total annual overhead for a freelancer S-Corp is typically $2,000–$5,000 more than remaining a sole proprietor.
Can a freelancer be both an LLC and an S-Corp?
Yes — and this is the most common setup for freelancers who incorporate. You form an LLC at the state level (for liability protection), then elect S-Corp tax treatment by filing Form 2553 with the IRS. The result is called an "LLC taxed as an S-Corp." The LLC governs your state liability; the S-Corp election governs your federal tax treatment.
