Key takeaways
- 1099 income in Kansas is subject to three taxes: 15.3% federal self-employment tax, 10% to 37% federal income tax, and 5.2% to 5.58% Kansas income tax.
- Set aside 25–30% of your profit in a high-yield savings account, so the money earns interest until your tax payments are due. For a single filer with no other income, total tax runs from 21.8% of profit at $40,000 to 31.5% at $200,000.
- Kansas has two income tax rates: 5.2% on the first $23,000 of taxable income ($46,000 married filing jointly) and 5.58% above that.
- Kansas estimated payments start at $500. If you expect to owe $500 or more, make quarterly estimated tax payments, due April 15, June 15, and September 15, 2026, and January 15, 2027.
- No local income tax. Wichita, Overland Park, and other Kansas cities and counties don’t tax income.

How Kansas taxes 1099 income
If you’re a freelancer, independent contractor, gig worker, or solo business owner in Kansas, your net profit (1099 income minus business expenses) is taxed three ways:
- Federal self-employment tax: 15.3% on most of your profit (92.35% of it). That’s 12.4% for Social Security, on earnings up to $184,500 in 2026, plus 2.9% for Medicare with no cap. It replaces the payroll taxes an employer would split with you. Estimate it with the self-employment tax calculator.
- Federal income tax: 10% to 37% on what’s left after three deductions: the $16,100 standard deduction ($32,200 married filing jointly), half of your self-employment tax, and the 20% QBI deduction.
- Kansas income tax: 5.2% to 5.58% on your profit minus half of your self-employment tax, the Kansas standard deduction, and the Kansas exemption. You report it on Form K-40.
What’s different about Kansas
- A small standard deduction and a large exemption. Kansas’s standard deduction is $3,605 ($8,240 married filing jointly), but every filer also gets a $9,160 exemption ($18,320 married filing jointly). Together, they shield $12,765 of income for a single filer.
- Most of your profit is taxed at 5.58%. Only the first $23,000 of taxable income ($46,000 married filing jointly) gets the lower 5.2% rate.
- No QBI deduction. The IRS lets you deduct up to 20% of your business profit. Kansas doesn’t. At $80,000 of profit, that’s $11,650 you deduct on your federal return but still pay Kansas tax on.
- Some federal deductions carry over. Because Kansas starts with the income on your federal return, three deductions you take there also lower your Kansas tax: half of your self-employment tax, self-employed health insurance premiums, and self-employed 401(k) contributions.
A self-employed person in Kansas at $80,000 pays $19,996: about $736 more than in California and $3,349 more than in Texas, which has no income tax.
Kansas income tax rates for 2026
Kansas’s rates and income ranges are set by law and aren’t adjusted for inflation.
| Rate | Single | Married filing jointly |
|---|---|---|
| 5.2% | $0 – $23,000 | $0 – $46,000 |
| 5.58% | Over $23,000 | Over $46,000 |
Example: Kansas tax on $80,000 of 1099 income
Here’s the math for a single self-employed person in Wichita with $80,000 of profit and no other income.
| Step | Amount |
|---|---|
| Self-employment tax: $80,000 × 92.35% × 15.3% | $11,304 |
| $80,000 minus half of self-employment tax | $74,348 |
| Income the IRS taxes: $74,348 minus the $16,100 standard deduction and $11,650 QBI deduction | $46,599 |
| Federal income tax | $5,344 |
| Income Kansas taxes: $74,348 minus the $3,605 standard deduction and $9,160 exemption | $61,583 |
| Kansas income tax: 5.2% on the first $23,000, 5.58% on the rest | $3,349 |
| Total 2026 tax | $19,996 (25.0%) |
Self-employment tax is the biggest piece. Every dollar you write off as a business expense lowers all three taxes, since your self-employment tax, federal income tax, and Kansas income tax are all based on your profit after expenses.
What tax write-offs can I claim?
How to lower your Kansas 1099 tax bill
At $80,000 of profit, every $1,000 of business expenses you deduct cuts about $282 from your total tax. Common write-offs for self-employed people in Kansas include:
- Your phone and internet, for the share you use for work
- Car expenses, using a set rate per mile or your actual costs (compare the two)
- A home office, if you use part of your home regularly and only for work (estimate yours)
- Software, equipment, and supplies you buy for your business
- Health insurance premiums you pay as a self-employed person
- Retirement contributions to a SEP-IRA or Solo 401(k)
Most of these are small purchases spread across a year of bank and card statements, which is where they get missed. See the full list of tax write-offs for self-employed people.

Try it freeKansas estimated tax payments
If you expect to owe $500 or more in Kansas tax for 2026 after withholding and credits, make estimated payments to the Kansas Department of Revenue online or with Form K-40ES. They’re due on the same dates as your federal payments, and each is a quarter of your Kansas tax:
| Payment | Share of your Kansas tax | Due date |
|---|---|---|
| 1st | 25% | April 15, 2026 |
| 2nd | 25% | June 15, 2026 |
| 3rd | 25% | September 15, 2026 |
| 4th | 25% | January 15, 2027 |
- Federal payments are separate: you pay the IRS on the same four dates with Form 1040-ES.
- To avoid a penalty for paying too little, pay at least 90% of this year’s Kansas tax or 100% of last year’s, whichever is less, in on-time payments.
- You can skip the January payment if you file your 2026 Kansas return and pay the full balance by January 31, 2027.

Should you form an LLC or S corp in Kansas?
You don’t need one to work as an independent contractor. If you work for yourself without forming a business, you report 1099 income on Schedule C, part of your regular tax return, and pay the taxes above.
- LLCs cost $90 to form, after Kansas cut its filing fees in 2026. Most businesses now file an information report with the Secretary of State every two years.
- S corps can make sense once your profit is around $80,000, when the self-employment tax savings get significant. You pay yourself a reasonable salary and take the rest as profit payouts (distributions) that aren’t subject to self-employment tax.
Run the numbers for your income to see what you’d save.
Do self-employed people in Kansas charge sales tax?
Usually not for professional services like writing, design, consulting, and bookkeeping. Kansas does tax repairing, installing, and servicing physical goods, along with the goods themselves, at a 6.5% state rate plus local taxes.
