What does this mean? Your expected business profit for the year after business expenses but before the owner's salary.
The IRS requires "reasonable compensation" for S-Corp shareholder-employees. The salary is capped at your current net profit.
This is an illustrative assumption, not a tax or an IRS-required amount. Real overhead depends on your payroll provider, your CPA, and your state.
Per IRS Form 8959, these are added to your business income to determine whether the 0.9% Additional Medicare Tax applies.
Sets the Form 8959 threshold: $200K (single / HOH), $250K (MFJ), $125K (MFS).

Federal delta = the LLC's self-employment tax minus the S-Corp's employer-side payroll tax. The S-Corp employer-side figure ishalf of the standard 12.4% + 2.9% FICA on the salary; the 0.9% Additional Medicare Tax is entirely employee-side (no employer match) and is not included in the S-Corp employer-side comparison. The $50 filing fee is not included — it's a one-time setup cost. Income tax, QBI, health insurance, and retirement contributions are not modeled.
Estimate. Methodology & scope
ESTIMATE. The figures above estimate the federal payroll / self-employment tax difference between a Single-Member LLC (Schedule C / Schedule SE) and an S-Corp election, plus New Mexico's modeled $0 annual report (no recurring franchise tax is currently modeled) and the one-time $50 New Mexico LLC filing fee (setup cost, not deducted from the year-1 net benefit). They do not include federal or New Mexico individual income tax (the state-income-tax flag is informational; the dollar amount is not modeled), the §199A QBI deduction (made permanent under the One Big Beautiful Bill Act, H.R. 1 / Public Law 119-21, signed July 4, 2025, with a 2026 phase-in range of $200K–$275K single / $400K–$550K MFJ), self-employed health insurance, retirement contributions, the half-of-SE-tax Schedule 1 adjustment, filing-status-specific deductions or credits, multi-state apportionment, reasonable-compensation enforcement, or other items that depend on your complete tax situation. The S-Corp administration overhead is a configurable illustrative assumption (defaulted to $1,200/yr), not a tax and not an IRS-required amount. Verify with a licensed CPA, EA, or tax attorney before acting.
02 · Why New Mexico specifically
The state-level numbers that move the answer.
An S-Corp election only pencils out when the federal payroll tax saved outpaces the recurring cost of running a corporate entity. New Mexicocharges $0per year to keep your entity in good standing and assesses ordinary state income tax on top of the federal figure.
At the calculator's default $100K / $50K inputs, the federal delta ($10,305) is what an LLC owner gives up in self-employment tax on net profit. After the New Mexico annual fee, the estimated net modeled benefit is$9,105.
State-specific note: New Mexico does not require an annual report fee for LLCs.
Localized formula — how this number was calculated
// New Mexico — same engine as the homepage
seBase = netProfit × 0.9235
ssPortion = min(seBase, 184_500) × 0.124
medicare = seBase × 0.029
addlMed = max(0, seBase + existingWages − 200_000) × 0.009
llcTax = ssPortion + medicare + addlMed
// S-Corp — employer-side payroll tax only
ssPortion = min(salary, 184_500) × 0.124
medicare = salary × 0.029
standard = ssPortion + medicare
addlMed = max(0, salary + existingWages − 200_000) × 0.009
// employee-side only — no employer match
scorpTax = standard / 2 // 50% of standard FICA — AddlMed excluded
// Net benefit
payrollDelta = llcTax − scorpTax
netOfFee = max(0, payrollDelta − 0)
savings = max(0, netOfFee − 1200) // $1,200 admin overhead- LLC filing: one-time $50 to form the entity in New Mexico.
