Kansas rules for construction & trades
- 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.
- 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.
Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
