This is a common crossover zone where a few thousand dollars of annual S-Corp costs, reasonable salary and state entity taxes can change the answer.
Calculate my actual S-Corp break-even →Small changes in salary or business expenses can move the modeled break-even materially, so a generic “S-Corp starts at $X” rule is especially unreliable here.
$75,000 of revenue can represent very different businesses. Business expenses reduce the profit available for salary and distributions, so two owners with the same revenue can reach opposite S-Corp conclusions.
The IRS does not provide a universal 60/40 safe harbor. Shareholder-employees who perform services must receive reasonable compensation before non-wage distributions. The salary should reflect the services performed and the facts of the business.
Payroll, bookkeeping, tax preparation, unemployment requirements and state business/entity taxes can consume part of the federal payroll-tax savings. The Analyze My Income calculator includes an annual S-Corp cost input and models standard-scenario state business/entity taxes across all 50 states.
Changing from sole proprietor to S-Corp can change qualified business income because shareholder wages are not QBI. At higher taxable income, wage/property limits and SSTB rules can also become relevant.
Analyze My Income compares modeled sole-proprietor take-home with modeled S-Corp take-home after federal income tax, self-employment or payroll tax, QBI, personal state income tax, modeled state business/entity taxes and the annual S-Corp costs you enter. It then searches for the revenue level where the two structures cross under your assumptions.
$75,000 is a starting revenue scenario, not a tax recommendation. A business with a different salary, expense structure, state, SSTB status or owner income profile can produce a materially different answer.
IRS guidance requires reasonable compensation for shareholder-employees who provide services; it does not provide a universal percentage split. Use the calculator as a planning estimate and professional advice for filing decisions.
