The comparison applies the entered payroll-tax rate to LLC self-employment earnings versus S-corp salary, then subtracts extra S-corp administration cost.

LLC vs S Corporation Tax Calculator: formula-based step-by-step solution

This LLC vs S Corporation Tax Calculator worked derivation uses the published default state. Its live formula panel replaces these values whenever an input, unit, mode, date, material, or scenario changes.

Governing formula or algorithm — exact production relationships:

Sal = min(v('salary'),v('profit'))
Llc SE = min(v('profit') × .9235,v('wageBase')) × v('seRate') ÷ 100
S Payroll = min(sal,v('wageBase')) × v('seRate') ÷ 100
Dist = max(0,v('profit')-sal)
Savings = llcSE-sPayroll-v('admin')
Llc Total = llcSE+v('profit') × v('incomeRate') ÷ 100
S Total = sPayroll+v('admin')+v('profit') × v('incomeRate') ÷ 100

1. Governing formulas and numeric substitution

Formula 1: Sal = min(v('salary'),v('profit'))
Default-value substitution: Sal = min(v('(80000)'),v('(150000)'))
Formula 2: Llc SE = min(v('profit') × .9235,v('wageBase')) × v('seRate') ÷ 100
Default-value substitution: Llc SE = min(v('(150000)') × .9235,v('(176100)')) × v('(15.3)') ÷ 100
Formula 3: S Payroll = min(sal,v('wageBase')) × v('seRate') ÷ 100
Default-value substitution: S Payroll = min(sal,v('(176100)')) × v('(15.3)') ÷ 100
Formula 4: Dist = max(0,v('profit')-sal)
Default-value substitution: Dist = max(0,v('(150000)')-sal)
Formula 5: Savings = llcSE-sPayroll-v('admin')
Default-value substitution: Savings = llcSE-sPayroll-v('(3500)')
Formula 6: Llc Total = llcSE+v('profit') × v('incomeRate') ÷ 100
Default-value substitution: Llc Total = llcSE+v('(150000)') × v('(24)') ÷ 100
Formula 7: S Total = sPayroll+v('admin')+v('profit') × v('incomeRate') ÷ 100
Default-value substitution: S Total = sPayroll+v('(3500)')+v('(150000)') × v('(24)') ÷ 100

2. Variables and measurement units used

Business profit before owner pay USD = 150000
Reasonable S-corp salary USD = 80000
Effective self-employment/payroll tax rate % = 15.3
Social Security wage base used USD = 176100
Extra annual S-corp payroll/tax/admin cost USD = 3500
Marginal income tax rate % = 24

3. LLC vs S Corporation Tax Calculator final evaluation: this calculator’s production engine evaluates the substituted relationship with unrounded internal precision; its subject-specific result cards, table, and visual report the rounded final answer and verification quantities.
