LLC vs S-Corp Tax Calculator

Compare default LLC (Schedule C) tax to S-corp election. Models reasonable salary, FICA on salary only, distributions outside SE tax, payroll/accounting overhead, and the real crossover.

Disclaimer: Estimates only. Reasonable compensation requirements, state-specific S-corp taxes, and payroll overhead vary materially. Consult a CPA before electing S-corp status.

$150,000

IRS requires 'reasonable comp' — usually 30–60% of profit, never under industry median W-2 for your role.

Typical: $1,200 payroll service + $1,000–$2,500 CPA for 1120-S.

Formula used

Entity-tax comparison

S-corp saves 15.3% on the distribution portion only. Income tax is roughly equal between structures because all profit still passes through to your 1040.

S-Corp saves = (LLC SE tax) − (Salary × 15.3% FICA) − (S-corp overhead)
Typical crossover
~$80–100k
Common salary ratio
40–60% of profit
Typical overhead
$2k–$4k/yr

What 'reasonable compensation' actually means

The IRS doesn't publish a fixed percentage — they look at industry W-2 medians for someone doing your work, time spent in the business, distributions relative to salary, and what you'd pay an arms-length employee to do the same role. RCReports, Glassdoor, and BLS OES data are the typical defenses. The most-audited pattern: $0 salary with full distributions. The safest pattern for a solo professional: 40–60% of profit as salary, never below the local W-2 median for your title.

Hidden costs of S-corp election

Beyond payroll and 1120-S filing, factor in state-level annoyances: California's $800 franchise tax + 1.5% S-corp tax on net income, New York's separate S-election form, and per-state payroll registrations if you have a remote team. These can shave $500–$2,000 off the projected savings; the calculator above models a flat overhead — adjust it upward for CA/NY/IL operators.

Rex's Notes

Every freelancer eventually gets the 'you should be an S-corp' speech from a tax prep ad. Sometimes it's right, often it's wrong, and the breakeven depends on five numbers: net income, reasonable salary, state, payroll cost, and the QBI deduction. This calculator runs both structures side-by-side so you see whether the SE tax savings actually beat the added compliance cost — or whether the default LLC is fine for now.

What each input means

Get these inputs right and the output is reliable. Get them wrong and the calculator just multiplies bad assumptions.

Net business income

Schedule C profit after all deductions, before owner compensation.

Typical range: $60k–$300k is the decision zone; under $60k stay sole prop/LLC, over $300k usually clear S-corp win.

Reasonable W-2 salary (S-corp)

What the IRS expects you to pay yourself if you elect S-corp. Must reflect market rate for your role.

Typical range: 50–70% of net income for service businesses; higher in professional services.

Payroll service + extra accounting cost

Real annual overhead of running S-corp: payroll software, separate accountant, more complex return.

Typical range: $1.5k–$4k/year.

State tax rate

Some states (TN, NH, CA) impose franchise or excise taxes on S-corps that erode federal savings.

Typical range: Check your state — CA's $800 minimum + 1.5% S-corp tax often kills the deal for incomes under $200k.

Worked examples

Real scenarios with the math walked through line by line.

Example

Designer, $100k net in Texas

Scenario: $100k net income, $70k reasonable salary, $2,500/yr payroll + accounting, 0% state.

Math: LLC: SE tax = $100k × 0.9235 × 0.153 = $14,130. S-corp: FICA on $70k salary = $10,710. Distributions of $30k avoid SE tax. SE tax savings = $3,420. Net after extra costs = $920 savings/yr.

Outcome: Marginal. The savings barely beat the hassle. Stay LLC unless income is growing fast.

Example

Consultant, $250k net in Texas

Scenario: $250k net income, $130k reasonable salary, $3,000/yr extra costs, 0% state.

Math: LLC: SE tax = $250k × 0.9235 × 0.153 ≈ $35,328 (capped on SS portion above wage base — actual ≈ $27k). S-corp: FICA on $130k = $19,890. SE tax savings ≈ $7k. Net after costs = ~$4k/yr saved.

Outcome: Clear S-corp win. Savings will grow as income grows since FICA caps out at $130k while LLC SE tax keeps the Medicare component.

Common mistakes

Where this calculation usually goes wrong in the real world.

  • Setting the S-corp salary too low to maximize distributions. IRS audits target this; 'reasonable comp' is a real standard.
  • Forgetting state-level S-corp taxes. California's $800 minimum franchise tax + 1.5% on net income often eliminates federal savings below $200k net.
  • Ignoring administrative cost. Payroll, separate returns, and accountant fees add $1.5–4k/year — real money on a $5k savings.
  • Missing the QBI deduction implications. The 20% QBI deduction works differently for sole props vs S-corp wages — the math can swing $3–5k in either direction.
  • Electing S-corp too early. Most service businesses should wait until net income is consistently $100k+ for 2+ years.

When to use this calculator

  • Deciding whether to elect S-corp status before March 15 (or for the new tax year).
  • After a big income jump — re-run when you cross $100k, $200k, $300k net.
  • When considering relocation to a different state.
  • Before adding employees or business partners (entity choice gets more complex).
  • When deciding to revoke an S-corp election that no longer pays off.

Glossary

Term

LLC (default tax)

Single-member LLC is a disregarded entity — taxed identically to a sole proprietor on Schedule C. Provides legal liability protection only, no tax difference.

Term

S-corp election

Form 2553 election that lets an LLC or corporation be taxed as an S-corp. Splits income between W-2 salary (subject to FICA) and distributions (not subject to SE tax).

Term

Reasonable compensation

IRS standard requiring S-corp owners to pay themselves a market-rate W-2 salary before taking distributions. Documentation matters in an audit.

Term

Distributions

Profit paid out to S-corp shareholders not subject to SE tax. The tax-saving lever — but only on the amount above your reasonable salary.

Term

QBI deduction

20% deduction on qualified business income. Different rules for sole prop vs S-corp wages can shift the comparison by thousands.

More questions answered

At what income level does S-corp become worth it?

Rough rule: $80–100k net is the floor where S-corp begins to pay off. Below that, the SE tax savings rarely beat the extra accounting + payroll cost. The cleaner answer requires plugging your specific state and salary into a side-by-side comparison — California, for example, often pushes the breakeven to $200k because of the 1.5% S-corp tax.

What's a 'reasonable' salary?

What you'd pay someone else to do your job. The IRS has won audits where owners paid themselves $0 or 'token' salaries while taking $200k+ distributions. Common benchmarks: 40–60% of net for service businesses with passive income components; 60–80% for businesses where the owner does substantially all the work. Document your reasoning with comp surveys (BLS, salary.com, RFP rates).

Can I switch back from S-corp to LLC?

Yes, but the IRS doesn't let you re-elect S-corp for 5 years after revoking. Don't switch in either direction without modeling 2–3 years of expected income first. A one-year experiment is usually a mistake.

FAQ

At what income should I elect S-corp status?

Most CPAs cite $80–$100k net profit as the crossover. Below that, payroll + 1120-S + state overhead typically eats the savings. Above $150k it's almost always worth it — savings scale with the distribution portion.

What's a reasonable S-corp salary?

Use industry W-2 medians for your role and experience. A solo software consultant should pay themselves at least ~$70–$100k (BLS senior dev median). A YouTuber-as-operator might justify lower if the business is largely passive content production. RCReports is the most-cited defensible report.

Can I have an LLC AND elect S-corp tax treatment?

Yes — this is the most common structure. Form an LLC with your state, then file Form 2553 with the IRS to elect S-corp tax status. You keep the LLC's liability protection and operational simplicity, plus the S-corp's SE-tax advantage.

What's the deadline to elect S-corp for 2026?

Form 2553 is due within 2.5 months of the tax year start — so March 15, 2026 for a calendar-year 2026 election. Late elections can still be granted with reasonable-cause relief under Rev Proc 2013-30 but it's avoidable hassle.
