What these figures count
  • State income tax, and state taxes on the business itself: franchise, LLC, S corp, gross receipts and excise taxes.
  • Social Security and Medicare on both sides of an owner salary, federal unemployment tax and the state's new-employer rate.
  • The 20% qualified business income deduction with its income limits and the professional-service rule.
  • Yearly report fees, and a cost you can change for payroll and the business tax return.

Many S corp calculators leave out state taxes and the QBI deduction, which can make the election look better than it is.
