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.

Questions

Should a dentist in Hawaii form an S corp?

At $190,000 of profit, not on these figures: the S corp costs $5,830 a year more than staying a sole proprietor.

Is an LLC worth it for a dentist in Hawaii?

For tax, a single-member LLC changes nothing: $78,151 a year against $78,141, the difference being Hawaii's LLC fees. It separates business liability and is the base for an S corp election.
