LLC vs S Corp: pros and cons.
The honest, side-by-side list of advantages and disadvantages of each structure, with the break-even profit level and the IRS's "reasonable compensation" rule called out.
Single-member LLC
LLC pros and cons
Pros
· Simpler tax filing
A default-taxed LLC reports business profit on Schedule C and pays self-employment tax via Schedule SE. There is no separate federal return for the LLC.
· No payroll required
You can take owner draws directly from the LLC without running a payroll account. Useful for businesses with variable monthly income.
· Flexible profit allocation
Multi-member LLCs can allocate profits and losses in non-pro-rata percentages (e.g., 60/40) by agreement. S Corporations cannot.
· Fewer state filings
Most states require an annual report, but no separate Form 1120-S, no Form 941, no state unemployment filings at the entity level.
· Lower setup & ongoing cost
One-time state filing fee ($35–$500) plus annual report fee ($0–$800). No payroll service or extra CPA fees required.
· Pass-through taxation
LLC profits pass through to the owner's personal return without entity-level federal income tax.
Cons
· Full SE tax on net profit
Every dollar of net profit is subject to 15.3% self-employment tax (12.4% Social Security capped at $184,500 for 2026, 2.9% Medicare uncapped) on 92.35% of net earnings.
· No payroll-tax optimization
There is no structural way to split owner compensation into salary + distribution, which is the core S-Corp tax benefit.
· Half-of-SE deduction does not fully offset
An LLC owner can deduct half of SE tax as an above-the-line adjustment, but the effective marginal cost is still meaningfully higher than the S-Corp route at higher profit levels.
LLC with S-Corp election
S Corp pros and cons
Pros
· Payroll-tax savings on distributions
The portion of profit taken as a distribution (after the W-2 salary) is not subject to 15.3% FICA — only ordinary federal (and state) income tax.
· QBI deduction preserved
S Corporations remain eligible for the §199A QBI deduction, unlike C Corporations. The election doesn't kill QBI.
· No entity-level federal income tax
Profit passes through to the owner's Form 1040 via Schedule K-1. No 21% corporate tax like a C Corp.
· Credibility & investor familiarity
Many banks, landlords, and contractors are familiar with S Corp filings. Form 1120-S is the standard small-business corporate return.
Cons
· Payroll is mandatory
You must run payroll on a W-2 salary — typically through a payroll service ($30–$100/month) — and file quarterly Form 941 plus state withholding filings.
· Reasonable salary requirement
The IRS requires the W-2 salary to be reasonable for the work performed. Setting it too low invites the IRS to reclassify distributions as wages, plus penalties.
· More expensive tax preparation
Form 1120-S (corporate return) plus Form 1040 (personal return) typically costs $500–$1,500+ more per year in CPA fees than a Schedule C sole-prop return.
· Fixed annual overhead
Payroll service + bookkeeping + extra return ≈ $1,200/yr modeled overhead. Below ~$60K profit this often wipes out the federal savings.
· Pro-rata distributions only
All S-Corp shareholders must receive distributions in proportion to ownership. You cannot allocate profits by agreement like an LLC.
· State franchise tax can wipe out the benefit
California ($800 minimum), Tennessee ($300), Delaware ($400), Massachusetts ($500/yr) and a handful of other states materially shrink or eliminate the federal savings.
The break-even picture
At low profit, the S-Corp admin overhead cancels out the federal savings. At higher profit, the savings scale up because more profit falls into the distribution (which is free of FICA). At $100K profit and a $50K salary in a no-fee state, the net modeled benefit is approximately $9,100/yr (federal only). At $200K profit with a $75K salary, the savings scale up substantially.
| Net profit | Salary | LLC SE tax | S-Corp employer FICA | Federal Δ (before admin) |
|---|---|---|---|---|
| $50,000 | $30,000 | $6,888 | $2,295 | $4,593 |
| $100,000 | $50,000 | $14,129 | $3,825 | $10,304 |
| $200,000 | $75,000 | $26,773 | $5,738 | $21,035 |

Frequently asked questions
What is the main advantage of an LLC?
Simplicity. A default-taxed single-member LLC is the easiest U.S. business structure to operate and the cheapest to maintain. No payroll, no separate federal return, flexible profit allocation, and a one-time state filing fee of $35–$500.
What is the main advantage of an S Corp?
Federal payroll-tax savings. The portion of profit taken as a distribution (rather than a W-2 salary) is free of the 15.3% FICA tax. For a single owner earning $80K–$200K net profit with a defensible reasonable salary, the savings usually exceed $5K–$15K/yr after admin overhead.
At what profit level does an S Corp make sense?
There is no IRS-defined threshold. As a rule of thumb, most advisors suggest $60K–$80K+ in consistent net profit before the S-Corp election pays for itself, once you account for the ~$1,200/yr modeled admin overhead.
Can an S Corp lose its tax benefit?
Yes. If the IRS determines your W-2 salary is not 'reasonable' for the services performed, it can reclassify distributions as wages, assess back payroll taxes, plus penalties and interest. The risk is highest when the salary is a small fraction of total profit.
Which is better for a solo freelance business?
For most solo U.S. service businesses, the LLC taxed as an S Corp produces the lowest federal payroll tax once profit justifies the extra paperwork. Below ~$60K profit, stay with a default LLC. Run your specific numbers with the calculator.
