Kansas Income Tax Overview

Kansas has a flat income tax rate of 5.2% with a standard deduction of $3,605 for single filers — one of the lowest standard deductions in the country, which means a large portion of gross income is exposed to the 5.2% rate. Kansas recently simplified from a multi-bracket system to a single flat rate. Kansas City, Kansas (on the Kansas side of the state line) does not charge a city income tax; however, Kansas City, Missouri charges a 1% earnings tax on wages earned within city limits on the Missouri side. No other Kansas city charges a local income tax on wages. Workers in Wichita, Overland Park, Olathe, and Lawrence all face the same statewide flat rate.

Here's what a single Kansas filer keeps in 2026. On a $50,000 salary, take-home is approximately $39,752 per year ($3,313/month) after federal, FICA, and state taxes. At $80,000, take-home is approximately $60,605 ($5,050/month), with the state taking $3,973. At $100,000, you keep about $73,635 ($6,136/month), with $5,013 going to Kansas. At $150,000, take-home is approximately $105,569 ($8,797/month), with the state taking $7,613. Kansas's effective rate is close to the full 5.2% for most earners due to the minimal standard deduction.

Compared to neighboring Missouri (flat 2% with the federal $16,100 standard deduction), a Kansas worker at $80,000 takes home approximately $2,695 less per year — a dramatic difference that has become a competitive issue along the Kansas City metro. Against Nebraska (top 4.55% with $8,850 deduction), Kansas workers at $80,000 pay approximately $1,268 more per year. Against Oklahoma (4.5% top rate with $6,350 deduction), Kansas workers pay about $873 more at $80,000. Kansas is among the higher-tax states in the Midwest relative to its neighbors.

Watch out: Kansas's 5.2% flat rate combined with a $3,605 standard deduction creates an effective rate for most workers that's close to the headline 5.2%. Contrast this with how Colorado's flat rate of 4.4% pairs with a $16,100 standard deduction — a Colorado worker at $80,000 pays $2,812 in state tax, while a Kansas worker pays $3,973. Even though Colorado's nominal rate is 4.4% vs Kansas's 5.2%, the deduction difference ($16,100 vs $3,605) accounts for much of the gap. When comparing flat-rate states, always check the standard deduction alongside the rate — the two together determine what you actually pay.
