What is the Kansas state income tax rate in 2026?

Kansas taxes income in 2 brackets from 5.20% to 5.58% in 2026; the top rate starts at $23,000 of taxable income for a single filer and $46,000 for a married couple filing jointly. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $1,665 of Kansas income tax (1.7% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $1,209 to Kansas and $4,111 federal.

In QuantCalc's 51-state planner study — one married couple, both 60, $2M, $80,000 a year to spend after tax, 10,000 paths per jurisdiction — the median path in Kansas pays $262,883 of federal and state income tax and Medicare IRMAA over 30 years, $98,769 of it Kansas state income tax, $100,286 more than in the 16 jurisdictions that charge this couple no state tax. That ranks #47 of 51 by lifetime tax (1 = lowest). The plan succeeds in 81.89% of paths. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.

The KS verdict

For a retiree planning withdrawals in 2026, Kansas is a middle-of-the-road state for retirement taxation. Social Security fully exempt since the 2024 special session, plus a universal personal exemption.

Kansas has no dollar-capped retirement-income exclusion, so every converted dollar enters the state tax base. The marginal cost of a conversion here is the federal bracket plus the state rate plus, below 65, whatever premium tax credit crossing the 400% FPL cliff would cost you.

Live ACA cliff check

The 400% FPL cliff is a federal threshold, but the dollars at stake depend on your county's benchmark Silver premium. Adjust the inputs below — every result is computed in your browser, no data is sent to QuantCalc.

Worked example: $30k Roth conversion in Kansas

Consider a married couple age 58 in Kansas with $75,000 of wages (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Kansas state tax on that conversion is $1,674 — 5.6% of the amount converted. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $24,589 a year at Kansas's average benchmark Silver premium. Total cost of the $30,000 conversion: $29,863, or an effective 99.5% marginal rate. Each Kansas tax figure for a conversion on this page is QuantCalc's state tax engine run on the couple's whole 2026 Kansas return twice, without the conversion and with it, with every amount split evenly between the two spouses, so Kansas's own brackets, deductions, exemptions and credits are all applied. The federal-state-ACA stack matters in Kansas.

Cost breakdown

ComponentAmount
Federal income tax (12% bracket)$3,600
Kansas state income tax$1,674
ACA premium tax credit clawback$24,589
Total cost on $30,000 conversion$29,863 (99.5% effective)

Scenario B (moderate): cliff-aware $34.6k conversion in Kansas

A Kansas couple aged 60, both on Marketplace coverage with $50K wages converts $34,600, which lifts their MAGI to exactly the $84,600 400% FPL cliff: still eligible, and they keep a premium tax credit of $25,722 a year. One more dollar of conversion would cost all of it. State tax: $1,845 — 5.3% of the amount converted. Federal income tax added: $4,012 (the whole conversion is taxed in the federal 10%–12% brackets). ACA PTC preserved. Total cost: $5,857, or 16.9% effective. In moderate-tax states, the conversion size is bounded by both the IRMAA two-year lookback and the ACA cliff — not state tax alone.

What the planner's Monte Carlo says about Kansas

QuantCalc Research ran one married couple through QuantCalc's retirement planner in each of the 51 jurisdictions: both 60, $2,000,000 ($1,400,000 traditional, $600,000 Roth), a 60/40 portfolio, $80,000 a year to spend after tax for 30 years, no Social Security, 10,000 paths each. The planner's federal and state tax engines price every year, and it picks the withdrawals and Roth conversions. Here is Kansas beside the lowest- and highest-tax results:

MetricKansasNo state tax (16 jurisdictions)Oregon (highest)

Across all 51 jurisdictions the success rate runs from 80.61% to 84.05%: for this couple the state changes the tax bill far more than the odds of the money lasting. Dollars are today's dollars.

How Kansas treats capital gains in retirement

Kansas taxes long-term capital gains as ordinary income at the same top bracket rate (5.58%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 5.58% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.

Why the ACA cliff hits hard in Kansas

The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Kansas's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $23,633 a year of premium tax credit at Kansas's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.

For 2026 the 400% FPL threshold is:

Roth conversion strategy for Kansas

The KS-specific playbook depends on tier:

  1. Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
  2. Stay under the cliff if you can. In Kansas at 5.58%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
  3. If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
  4. Coordinate with capital gains and the 0% LTCG bracket. Kansas taxes long-term capital gains as ordinary income at the same top bracket rate (5.58%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 5.58% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
  5. Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Kansas resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

What a year-end move does to your Kansas and federal tax in 2026

Each move changes three bills at once: the federal return, the Kansas return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).
