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 changes between the two

A sole proprietor pays self-employment tax of 15.3% on 92.35% of all profit, up to the Social Security wage base of $184,500. Taxed as an S corp, the business pays you a salary, and only the salary carries Social Security and Medicare tax. The rest comes out as a distribution.

The election adds costs: a payroll service, a separate business tax return (Form 1120-S), federal and Rhode Island unemployment tax on the salary, and Rhode Island S corporation minimum tax. The calculator counts $1,800 a year for payroll and the return. The IRS expects a reasonable salary for the work, so it cannot be set near zero.

A sole proprietor cannot elect S corp status alone: forming an LLC first ($150 in Rhode Island) and electing on Form 2553 is the usual route.
