The single most common piece of advice freelancers get when they start earning real money is "you should set up an LLC." Sometimes that advice comes from a lawyer, sometimes from a friend, sometimes from a Reddit thread. It's usually not wrong, but it's often incomplete — because the LLC question and the tax-savings question are two completely different questions that most people conflate.
This guide separates them. Here's how each structure actually works, when each one saves you money, and the income threshold where the math changes.
Sole Proprietorship: The Default (and Not a Bad One)
If you're freelancing and haven't formed any entity, you're operating as a sole proprietor. This is not a legal structure you chose — it's the default when a person earns self-employment income without a business entity.
Taxes as a sole prop:
- All net business income is reported on Schedule C
- Net profit is subject to self-employment tax: 15.3% on the first $168,600 (2024), 2.9% above that
- You can deduct half of your SE tax on your 1040
- Income then flows through to your Form 1040 and is taxed at your ordinary income rate
The downside of sole proprietorship is liability: your personal assets (savings, car, home) are fully exposed to business debts and lawsuits. There is no separation between you and your business.
For low-revenue freelancers testing the market, sole prop is a perfectly reasonable place to start. Don't let anyone tell you that you're irresponsible for not having an LLC at $15,000 in annual freelance income.
LLC: Liability Protection, Not a Tax Cut
A Limited Liability Company (LLC) is a state-level legal structure, not a tax classification. This distinction matters enormously.
For tax purposes, a single-member LLC is a disregarded entity — the IRS ignores it. Your income is still reported on Schedule C. You still pay SE tax the same way. From a tax perspective, nothing changes.
What does change: you now have a legal firewall between your personal assets and your business. If a client sues you, or you have a business debt you can't pay, your personal savings are generally protected — as long as you maintain the separation properly (keep separate bank accounts, don't commingle funds, sign contracts as the LLC).
LLC Formation Costs
State filing fees vary significantly:
- Low-cost states: Kentucky ($40), Colorado ($50), Missouri ($50)
- Mid-range: Texas ($300), Illinois ($150), Virginia ($100)
- High-cost: Massachusetts ($500), California ($70 to file + $800 annual minimum franchise tax)
You'll also want a registered agent (typically $50-150/year), a separate business bank account, and potentially an operating agreement (often a template suffices for single-member LLCs).
Bottom line on the LLC: it's often worth forming once you have real clients, real contracts, and real revenue — not because of tax savings, but because liability protection has real value. For someone doing occasional freelance work with trusted clients, it's less urgent.
S-Corp Election: Where the Actual Tax Savings Live
Here's where it gets interesting. An S-Corp is not a separate legal entity — it's a tax election you make with the IRS using Form 2553. An LLC can elect S-Corp status. A corporation can elect S-Corp status. You don't form an S-Corp, you elect to be taxed as one.
How S-Corp Taxation Works
Under S-Corp taxation, you are both the owner and an employee of your business. The structure works like this:
- Your business earns, say, $120,000 in net profit
- You pay yourself a reasonable salary — let's say $80,000
- The $80,000 salary is subject to payroll taxes (the equivalent of SE tax): your employer share + employee share add up to roughly the same 15.3% rate
- The remaining $40,000 flows through to your personal return as an owner distribution
- That $40,000 distribution is not subject to self-employment or payroll tax
That's the savings: the distribution portion avoids the 15.3% SE/payroll tax.
The S-Corp Math at $100,000 Net Profit
Let's run the numbers clearly:
As a sole prop:
- $100,000 net profit
- SE tax: $100,000 × 15.3% × 0.9235 (the SE tax base adjustment) ≈ $14,130
- Income tax applies on top of that
As an S-Corp with $70,000 salary and $30,000 distribution:
- Payroll taxes on $70,000 salary ≈ same as SE tax on $70,000 ≈ ~$9,890
- $30,000 distribution: no SE/payroll tax
- SE tax savings: roughly $30,000 × 15.3% × 0.9235 ≈ $4,240/year
Now subtract the cost of maintaining the S-Corp structure:
- Payroll processing (Gusto, ADP, or similar): $50-100/month = $600-1,200/year
- Additional accounting/tax preparation: $500-1,500/year for the more complex return
- State franchise taxes and fees: varies
Net annual savings at $100,000 profit: roughly $1,500-3,000 after costs, depending on your state and payroll setup.
The Break-Even Point: Roughly $50,000-$60,000 in Net Profit
At low income levels, the S-Corp math simply doesn't work. Here's why:
- At $50,000 net profit, a reasonable salary might be $45,000 (you can't pay yourself an unreasonably low salary to game the system)
- The distribution is only $5,000
- SE tax savings on $5,000: about $720
- That doesn't cover the cost of payroll processing and the additional tax return
The consensus among tax professionals is that S-Corp election generally makes sense when net self-employment income reaches $50,000-$60,000 or more, and becomes increasingly valuable as income grows.
At $200,000+ in net profit, the savings can be $10,000-15,000 per year or more, making the structure highly worthwhile.
The "Reasonable Salary" Requirement
The IRS requires S-Corp owner-employees to pay themselves a reasonable salary for the services they perform. This is not optional and not flexible.
Reasonable salary means what you'd pay a market-rate employee to do your work. If you're a freelance web developer earning $180,000 and you pay yourself a $20,000 salary, the IRS will reclassify much of your distribution as wages and hit you with back payroll taxes, interest, and penalties.
A defensible reasonable salary is typically in the range of 40-60% of your net profit for most service-based freelancers, though it varies by industry. Document your rationale.
The QBI Deduction: §199A
The Qualified Business Income (QBI) deduction, also called the §199A deduction, lets eligible self-employed individuals and pass-through entity owners deduct up to 20% of qualified business income from their federal taxable income.
This applies to sole proprietors, single-member LLCs, and S-Corps alike. At lower income levels, it's straightforward — deduct 20% of your net business income.
At higher incomes, limitations apply:
- Above $182,050 (single) or $364,200 (married filing jointly) for 2024, wage and capital limitations start to phase in
- For Specified Service Trades or Businesses (SSTBs) — which include consulting, law, health, financial services, and similar fields — the QBI deduction phases out completely above those income thresholds
If you're a freelancer in an SSTB field earning above the threshold, the QBI deduction may be limited or eliminated, which changes the tax-planning calculus.
When NOT to Elect S-Corp
The S-Corp structure is not always the right move. Skip it when:
- Net profit is below $50,000-$60,000: the costs exceed the savings
- Your income is irregular: payroll requires consistency; erratic revenue makes it harder to set a reasonable salary without triggering issues
- You're in an SSTB at high income: if the QBI deduction phases out, one of the remaining benefits of pass-through structure is reduced
- You're not ready for payroll compliance: missed payroll tax deposits create penalties; if you're not organized enough to run payroll, don't add that obligation
Formation Checklist if You Elect S-Corp
If you decide the math works for you:
- Form an LLC in your state (if you haven't already)
- File Form 2553 with the IRS to elect S-Corp tax treatment (must be filed within 2 months and 15 days of the start of the tax year you want it to apply)
- Set up payroll through Gusto, ADP, Paychex, or a similar service
- Open a dedicated business bank account (if you haven't)
- Run payroll at least quarterly (monthly is more common)
- Make timely payroll tax deposits (quarterly Form 941)
- File Form 1120-S (the S-Corp return) plus your personal 1040 with Schedule K-1
The additional administrative overhead is real. Factor it in honestly before deciding.
