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.

What matters for physicians

The IRS treats this work as a specified service trade or business, so the 20% QBI deduction phases out above $201,750 of taxable income (single). Health is a specified service under Treas. Reg. 1.199A-5(b)(2)(ii), which covers medical services by physicians, nurses, dentists and similar practitioners. law.cornell.edu
Pay figure is for family medicine physicians, the largest group with a published median. Many states make licensed professionals use a professional LLC or professional corporation, and California does not let an LLC render services that need a state license, so check the state board before forming. leginfo.legislature.ca.gov
