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 the switch takes in New Hampshire

File the Articles of Incorporation (Form 11) with the state: $100 (fee).
Federal return each year: Form 1120-S, due March 15, plus your own Form 1040.
State upkeep each year: Annual Report, $100 a year, due April 1.

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 Certificate of Formation (Form LLC-1) and Annual Report, $100 a year, a corporation files Articles of Incorporation (Form 11) and Annual Report, $100 a year.

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.
