This article is for informational purposes only and is not tax advice. Tax rules change annually and individual situations vary significantly. Consult a CPA or enrolled agent before making any decisions about business structure.
The most common piece of financial advice freelancers get after crossing $80,000 in income is: “You should get an S-Corp.”
The advice is usually right, but it skips the part that matters: when is the math actually favorable? What does it cost to run one? What are the IRS rules you cannot get wrong? And what’s the one tax interaction that most articles don’t bother mentioning because it’s complicated and the answer isn’t clean?
That’s what this article covers.
LLC and S-Corp are not two things you choose between
Most articles frame this as a binary decision. They’re not.
An LLC is a legal structure created under state law. An S-Corp is a federal tax election you make with the IRS. The two coexist. Most freelancers who “become an S-Corp” actually do two things:
- Form an LLC in their state (if they haven’t already)
- File IRS Form 2553 to elect S-Corp tax treatment
The LLC stays in place. The liability protection remains. The operating agreement remains. The only thing that changes is how the IRS taxes your income. This matters because it means you’re not choosing between two structures — you’re layering a tax strategy onto one.
What you’re paying now as a default LLC
When you form a single-member LLC without any additional elections, the IRS treats it as a sole proprietorship by default. All profits flow directly to your personal return on Schedule C.
That means 100% of your net profit is subject to self-employment tax: 15.3% applied to 92.35% of net profit, which works out to roughly 14% effective. Federal and state income tax on top of that.
Forming an LLC alone changes none of this. This surprises a lot of new freelancers who expect the business structure to come with tax benefits. The liability protection is real and worth having. The tax situation is identical to operating as a sole proprietor until you make an additional election.
For a detailed breakdown of how SE tax works, the self-employment tax guide on ChargeWhat.app covers the calculation, the 92.35% multiplier, and quarterly payment requirements.
What the S-Corp election actually does
When you elect S-Corp treatment, the IRS allows you to split your business income into two buckets:
A salary — paid to yourself as an employee of your own business, subject to payroll taxes (the equivalent of SE tax) just like any W-2 employee.
Distributions — profit paid out to yourself as an owner, which is not subject to payroll taxes.
The savings come from the second bucket. Every dollar taken as a distribution instead of salary avoids the 15.3% SE tax. On $60,000 in distributions, that’s roughly $8,500 saved.
A freelancer with $120,000 in net profit, compared across both structures:
| Default LLC | LLC with S-Corp Election | |
|---|---|---|
| Net profit | $120,000 | $120,000 |
| Reasonable salary | — | $60,000 |
| Distributions | — | $60,000 |
| SE / payroll tax | ~$16,500 | ~$8,500 |
| Compliance costs | ~$400 | ~$2,000 |
| Net annual savings | — | ~$6,500 |
At higher income levels the savings grow substantially. A freelancer earning $200,000 might save $15,000 or more annually after compliance costs. The math is compelling — which is why the advice is common, and why the details matter.
The breakeven point
The S-Corp election is not free. Running payroll, filing a separate Form 1120-S, and maintaining compliance typically costs $1,500–$3,000 per year in additional accounting and payroll service fees. That cost has to be weighed against the SE tax savings.
The consensus across tax professionals:
| Net profit | Recommendation |
|---|---|
| Under $50,000 | Stay as default LLC — compliance costs likely exceed savings |
| $50,000–$80,000 | Run the specific numbers with a CPA — it depends on your situation |
| $80,000+ | S-Corp election almost always makes financial sense |
| $500,000+ | Explore additional strategies with a CPA beyond S-Corp alone |
One important caveat: if your income is highly variable year to year — $40,000 one year, $150,000 the next — an S-Corp is harder to manage. You’re required to set a reasonable salary at the start of the year and run payroll consistently. Irregular income makes that planning more difficult.
The reasonable salary requirement
This is the compliance issue the IRS scrutinizes most closely. Get it wrong and the savings disappear — plus penalties and interest.
When you elect S-Corp treatment, the IRS requires that you pay yourself a reasonable salary for the work you perform in the business before taking any distributions. You cannot pay yourself $20,000 and take $180,000 in distributions to avoid payroll taxes. The IRS has successfully challenged exactly this in court — Radtke v. United States and Watson v. United States (8th Cir. 2012) are the standard references — and will reclassify distributions as wages when the salary is clearly unreasonable.
Reasonable salary means: what would you pay an unrelated employee to do the same work?
How to determine yours:
- Look up Bureau of Labor Statistics wage data for your role
- Check comparable salaries on LinkedIn, Glassdoor, or industry surveys
- Consider your location, experience level, and hours worked
- Document your reasoning in writing
Many CPAs use 40–60% of net income as a starting point, but the right number depends on your specific role and market rates. A consultant earning $200,000 who pays themselves $100,000 in salary and takes $100,000 in distributions is broadly defensible. The same consultant paying themselves $30,000 is not.
The salary must run through actual payroll — proper withholding, quarterly payroll tax deposits, and a W-2 issued at year end. Transferring money to yourself and calling it a salary does not satisfy the requirement.
What S-Corp compliance actually costs
Ongoing annual costs:
- Payroll service (Gusto, ADP, QuickBooks Payroll): $500–$1,500/year
- Additional tax preparation — Form 1120-S is significantly more complex than Schedule C: $500–$1,000 more than you currently pay
- Quarterly payroll tax deposits (late deposits trigger penalties starting at 2%)
- W-2 filing at year end
One-time setup costs:
- State LLC formation (if you don’t have one): $50–$500 depending on state
- IRS Form 2553 filing: free, but it needs to be filed correctly
Total additional annual cost: roughly $1,500–$3,000
At $50,000 net profit, SE tax savings might be $2,000–$3,000 — barely covering compliance costs and not worth the administrative burden. At $100,000 net profit, savings might be $7,000–$9,000, making the election clearly worthwhile. The breakeven is real, and it sits somewhere between those two numbers depending on your specific costs and salary level.
The election deadline
To have S-Corp tax treatment apply for the current calendar year, you must file Form 2553 by March 15. Missing it by a day means waiting until next year.
For new businesses, there is a 2-month-and-15-day window from the date of formation to file retroactively.
The election is not permanent. You can revoke it if circumstances change, though doing so has its own timing requirements and a 5-year waiting period before re-electing.
The QBI interaction most guides skip
The Qualified Business Income deduction allows eligible business owners to deduct up to 20% of qualified business income from their taxable income. It was made permanent under the One Big Beautiful Bill Act and applies to S-Corp distributions.
Here is where the tension lives: salary income is not eligible for the QBI deduction. Only distributions are.
A lower salary means more distributions, which means more QBI-eligible income and a larger deduction. But a lower salary also increases audit risk — and may not hold up if the IRS challenges your reasonable compensation.
One important caveat for freelancers: many fall into the IRS’s Specified Service Trade or Business (SSTB) category — consulting, design, writing, and similar knowledge-work fields are all included. For SSTBs, the QBI deduction phases out completely once taxable income exceeds $276,775 (single) or $553,500 (married filing jointly) in 2026, with the phase-out beginning at $201,775 and $403,500 respectively.
For most freelancers below those thresholds, the SE tax savings from distributions outweigh the QBI impact. At higher income levels the calculation gets genuinely complex, and optimizing salary level, SE tax savings, and QBI simultaneously is not something to model on a spreadsheet without professional guidance.
This is the area where working with a CPA is most clearly worth the cost.
A simple decision framework
Stay as default LLC or sole proprietor if:
- Your net freelance profit is consistently under $50,000
- Your income is highly variable year to year
- You’re not yet willing to manage payroll and additional compliance
- You’re in your first year of freelancing and still establishing your income level
Run the numbers with a CPA if:
- Your net profit is in the $50,000–$80,000 range
- You’re approaching the threshold and want to plan ahead
- You’re unsure how to determine a reasonable salary for your role
Elect S-Corp treatment if:
- Your net profit consistently exceeds $80,000
- You can set a defensible reasonable salary
- You’re comfortable managing payroll or willing to pay a service to do it
- The projected SE tax savings meaningfully exceed $2,000–$3,000 in compliance costs
Key numbers for 2026
- SE tax rate: 15.3% (12.4% Social Security + 2.9% Medicare)
- Social Security wage base: $184,500
- S-Corp election deadline: March 15 for calendar-year businesses
- New business election window: 2 months and 15 days from formation
- QBI deduction: 20% of qualified business income (permanent, OBBBA)
- QBI phase-out threshold: $201,775 single / $403,500 married filing jointly
- Typical compliance costs: $1,500–$3,000/year
- Breakeven profit level: $50,000–$70,000 net profit
Where to start
If you’re in the early stages of freelancing — earning under $60,000 — structure optimization is not the most valuable thing to focus on right now. Accurate rate-setting is. Most freelancers who undercharge do so because they never ran the real numbers on what they need to earn before the S-Corp question even becomes relevant.
The ChargeWhat freelance rate calculator works backwards from your target take-home and accounts for SE tax, state income tax, health insurance, business expenses, and a profit buffer. Free, no signup required.
Once your income grows to the point where business structure becomes the question, an LLC vs S-Corp calculator is on the roadmap. In the meantime, a CPA is the right tool for that conversation.
Tax rates, thresholds, and rules referenced are based on 2026 federal figures and are subject to change. Individual tax situations vary significantly based on filing status, state of residence, income level, and other factors. Consult a licensed CPA or enrolled agent before making any decisions about business structure or tax elections.
