S corporation in Kansas: what the election changes

Kansas adds little to the S-corp math. The business owes no state tax, and the new cost is unemployment tax on your salary.

You’ll need: last year’s Schedule C (line 31) and the W-2 from any job you also hold. Everything else starts at a typical value you can change.

State where the business is Each state treats the election differently. The check shows only the questions that matter there.

Net profit for the year, before paying yourself Your business's profit after expenses. Money you take out for yourself does not lower it.

Where do I find this?

Schedule C, line 31 (“Net profit or (loss)”) on last year’s return.

For this year: sales minus business expenses so far, scaled to a full year. Owner draws are not an expense.

Salary you would pay yourself as an S corporation What you would pay yourself through payroll. The IRS expects a reasonable salary for the work you do.

Where do I find this?

No form shows this yet: you choose it. It should be about what you would pay someone else to do your work.

The salary finder just below shows what employees in your job earn in your state or metro area. What the IRS looks at.

Typical values: change them if you know yours

Payroll service, per year typical value Published one-person prices: $492 to $684 a year (October 2026).

Your payroll provider’s price page or quote, for one employee: you. Published prices compared.

Extra tax-prep cost for the S-corp return typical value A survey average: the fee for Form 1120-S minus the fee for Schedule C (2020 fees).

Where do I find this?

Ask your preparer what a Form 1120-S (the S corporation’s own return) would cost, then subtract what you pay now for Schedule C.

Your top federal income tax rate Not sure? Keep 22%. It changes line 5 only.

Where do I find this?

Your taxable income is on Form 1040, line 15. Find the rate for that income and your filing status in the IRS rates and brackets table.

Filing status Changes the result only above $200,000 of earnings ($250,000 if married filing jointly, $125,000 if married filing separately).

Where do I find this?

The box checked under Filing Status at the top of your Form 1040.

The state

Kansas follows the federal S election; there is no separate state election. The S corporation files Form K-120S each year.

Kansas puts no income or franchise tax on an S corporation. You report the income on your own return, at the same rates as a sole proprietor’s profit: 5.2% up to $23,000 and 5.58% above that for a single filer in 2026.

Every business on file with the Secretary of State submits an information report every two years. An LLC that elects files the same report on the same schedule.

Unemployment tax on your salary

Unemployment insurance: 1.75% for a new non-construction employer on the first $15,100 of wages in 2026. A new employer keeps that rate until it has 24 months of experience. Kansas law covers any active officer of a corporation.

The optional pass-through entity tax

Under the SALT Parity Act, an S corporation can elect each year on Form K-120S to pay tax at the entity level at 5.58%. You get a credit for your share, and any excess is refunded. The calculator leaves it out.

Worked examples

A single-member LLC owner, single filer, 22% federal bracket, default payroll and return costs. The figure is total tax and added costs as an S corporation compared with staying as you are.

Profit / salary	Statewide
$80,000 / $45,000	$717 lower
