Kansas simplified its income tax to a 2-bracket system for 2026: 5.20% on income up to $23,000, then 5.58% on income over $23,000 (applied to taxable income after Kansas's own standard deduction and personal exemption, $12,765 combined). The old 3-bracket system (3.1%, 5.25%, 5.7%) has been replaced. The 5.58% top rate kicks in at just $23,000, making Kansas effectively a near-flat 5.58% tax for most middle- and upper-income earners. At $100K income: $4,781 state tax (4.78% effective rate).
How it compares regionally:
Kansas City border consideration: If you live in Kansas City, the KS side charges $4,781 at $100K vs Missouri side at $3,670 — the MO side now saves $1,111/year. This has shifted the KC border calculus since Missouri's cuts took MO below Kansas.
Note: These are marginal rates — you only pay the higher rate on income within each bracket.

Tax considerations if moving here:
| State | Tax Rate | Tax on $100K Income | Difference from Kansas |
|---|---|---|---|
| Kansas | 5.20-5.58% | $4,781 | Baseline |
| Missouri | 0-4.7% | $3,670 | −$1,111 (save) |
| Oklahoma | 0-4.5% | $3,955 | −$826 (save) |
| Nebraska | 2.46-4.55% | $3,670 | −$1,111 (save) |
| Colorado | 4.4% flat | $3,692 | −$1,089 (save) |
Key insight: Kansas's 5.58% effective top rate is now MORE expensive than every state in its regional cluster: Missouri (4.7%, $3,670 at $100K — saves $1,111/year vs KS), Nebraska (4.55% top, $3,670 at $100K after the personal exemption credit — saves $1,111/year vs KS), Oklahoma ($3,955 — saves $826/year vs KS), and Colorado (4.4% flat, $3,692) also beats Kansas. This makes Kansas the most expensive state for income tax in the KS/MO/NE/OK/CO regional cluster. The old narrative where KS and MO were comparable no longer holds — MO's tax cuts have left Kansas significantly behind.
The total picture:
Kansas simplified to 2 tax brackets for 2026: 5.20% on income up to $23,000, and 5.58% on income over $23,000. These rates apply to taxable income (after Kansas's own $3,605 standard deduction and $9,160 personal exemption). The 5.58% top rate kicks in at $23,000, meaning most earners pay 5.58% on the bulk of their income. At $100K income, Kansas state tax is $4,781 (4.78% effective rate). Kansas's rates are higher than neighboring Missouri (4.7%) and Iowa (3.8% flat).
Kansas has 2 tax brackets: 5.20% ($0-$23,000) and 5.58% (over $23,000). These are marginal rates applied to taxable income. The low $23,000 threshold means virtually all middle- and upper-income earners pay 5.58% on most of their income. At $100K gross income with Kansas's own $3,605 standard deduction + $9,160 exemption = $87,235 taxable: first $23,000 at 5.20% ($1,196) + remaining $64,235 at 5.58% ($3,584) = about $4,781 total state tax (Kansas tax table).
Missouri now clearly beats Kansas. At $100K income: Kansas charges $4,781, Missouri charges $3,670 — Missouri saves $1,111/year. Missouri has cut rates (top rate now 4.7%) while Kansas moved from a 3-bracket to a 2-bracket system but kept rates high. For Kansas City metro residents: living on the Missouri side now saves $1,111/year in state income tax plus approximately $820/year in property tax (MO 0.96% vs KS 1.37% average) = ~$1,931/year total advantage for the MO side.
Kansas does not tax Social Security benefits. Beginning with tax year 2024, all Social Security benefits included in federal AGI can be subtracted, regardless of income (Senate Bill 1, 2024 special session). Other retirement income, such as pensions and IRA withdrawals, may still be taxable, so check Kansas Department of Revenue guidance for your situation.
Move if: you're relocating from a higher-tax state (savings depend on income and state), seeking very low cost of living (median home $193K), work in Kansas City metro, employed in agriculture/aerospace, or prefer small-town/rural lifestyle. Stay away if: you can move to no-income-tax states like Texas/Florida, seek urban amenities (only KC/Wichita/Lawrence have them), or prioritize outdoor recreation (limited vs Colorado).
