Kansas rules that apply
- State income tax (2026)
- Kansas has a graduated state income tax for 2026: 5.2% to 5.58% (top rate starts at $23,000 for single filers). Single filers pay 5.2% on taxable income up to $23,000, then $1,196 plus 5.58% of the excess. Married filing jointly brackets are $46,000. The SB 269 revenue trigger did not cut rates for 2026 (KDOR Notice 25-06): https://ksrevenue.gov/taxnotices/notice25-06.pdf
- State estimated tax
- Required if your Kansas tax after withholding and credits is $500 or more, and withholding and credits may be less than the smaller of 90% of 2026 tax or 100% of 2025 tax. Same dates as federal (April 15, June 15, and September 15, 2026, and January 15, 2027). Form K-40ES.
- Minimum wage (2026)
- $7.25 an hour; tipped cash wage $2.13 an hour. Kansas's state rate matches the federal $7.25 and doesn't apply to employers and employees covered by the federal Fair Labor Standards Act (Kansas DOL: https://www.dol.ks.gov/employers/workplace-laws). Under federal law the maximum tip credit is $5.12.
- Portable benefit plans for independent contractors (HB 2602, 2026)
- Hiring parties can contribute to an independent contractor's portable benefit account, or withhold contributions with the contractor's consent. The account covers health, income-replacement, disability, or life insurance, or retirement. Contributions can't be used to decide employment classification. Starting with tax year 2027, contributions are a Kansas income tax subtraction.
- Rideshare (TNC) driver classification (K.S.A. 8-2722)
- Transportation network company drivers are independent contractors if the company sets no required login hours and doesn't restrict use of other platforms or other work. Both sides must also agree in writing that the driver is an independent contractor.
