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.

Federal and Ohio tax and fees, single filer, revenue 1.5 times profit, default salary for S and C corps. "Difference" is S corporation minus LLC taxed as an S corp.

What the switch takes in Ohio

File the Articles of Incorporation, for-profit with the state: $99 (fee).
Federal return each year: Form 1120-S, due March 15, plus your own Form 1040.
State upkeep each year: no yearly report fee.

What changes between the two

Both are taxed the same way by the IRS once the election is made: salary with payroll tax, the rest as a distribution, one Form 1120-S. The difference is state law: an LLC files Articles of Organization (Form 610) and no yearly report fee, a corporation files Articles of Incorporation, for-profit and no yearly report fee.

A corporation also has formalities an LLC skips: a board, bylaws, share records and yearly minutes. Most one-person businesses pick the LLC route for that reason.
