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.

Register with Alabama 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 Alabama unemployment tax at 2.7% on the first $8,000 of wages. workforce.alabama.gov See what payroll costs.
Federal return each year: Form 1120, due April 15 for a calendar year.

What changes between the two

A C corporation pays 21% federal tax and Alabama 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 Alabama?

Nothing. C corporation costs $4,523 a year more ($31,270 against $26,747).

When does a C corp make sense in Alabama?

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.
