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 Alaska

Either convert the LLC to a corporation under state law, or keep the LLC and elect corporate tax treatment with IRS Form 8832.
Register with Alaska as an employer and run payroll for your own salary: federal Forms 941 each quarter, Form 940 and a W-2 each year. New employers pay Alaska unemployment tax at 1% on the first $54,200 of wages. labor.alaska.gov See what payroll costs.
Federal return each year: Form 1120, due April 15 for a calendar year.
State upkeep each year: Biennial Report, $100 every two years, due January 2 every two years (even or odd year matching the year of incorporation).

What changes between the two

A C corporation pays 21% federal tax and Alaska corporate tax on its profit, and the owner pays tax again on dividends (the double tax). An LLC pays no federal income tax itself: profit lands on the owner's return, where the 20% qualified business income deduction can apply.

The figures assume all C corp profit after tax is paid out as dividends. Profit kept in the company to grow it is taxed only at the corporate rate until it is paid out, which is where a C corp can come out ahead.

Questions

How much does it save at $100,000 in Alaska?

Nothing. C corporation costs $3,517 a year more ($25,951 against $22,434).

When does a C corp make sense in Alaska?

Mostly when profit stays in the company, when outside investors need one, or for the qualified small business stock exclusion. For an owner who takes the profit out, the second tax on dividends usually costs more. On these figures it never costs less up to $500,000.
