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 Nebraska

File the Certificate of Organization with the state: $100 (fee). Nebraska also requires a newspaper notice, about $125.
Get an EIN from the IRS (free, online) and open a business bank account in the new name.
Federal return each year: Schedule C with your Form 1040, due April 15.
State upkeep each year: Biennial Report, $28 every two years, due April 1 of odd-numbered years (delinquent after June 16).

What changes between the two

A single-member LLC is a disregarded entity for income tax: it files the same Schedule C and pays the same self-employment and income tax as a sole proprietor. What it adds in Nebraska is $100 to form, about $125 for the newspaper notice and Biennial Report, $28 every two years.

What it gives: business debts and claims stay with the LLC, as long as business and personal money stay apart. Many banks, clients and platforms ask for one. It is also the step before an S corp election, with no new company needed.
