Kansas for retirees: Social Security and public pensions out, IRAs and private pensions in

The Kansas return asks one question of a retiree’s income: where did it come from? Social Security comes off in full on Schedule S line A10, with no income limit since 2024. A pension from KPERS, the Kansas Police and Firemen’s system, the Kansas teachers’ or judges’ systems, federal civil service, the military, the Thrift Savings Plan or Railroad Retirement comes off in full on line A14, at any age. Everything else a retiree draws, a private employer’s pension, a traditional IRA, a 401(k) or 403(b), a commercial annuity, a Roth conversion, stays in Kansas income and is taxed at 5.2% up to $23,000 of taxable income ($46,000 joint) and 5.58% above. Kansas has no general retirement exclusion and no age-based pension deduction. A retired teacher living on KPERS and Social Security owes Kansas nothing. A retired engineer living on a 401(k) and Social Security pays Kansas on most of the 401(k).

What softens the second case is the rest of the Kansas return. The personal exemption is $18,320 for a couple ($9,160 single), the standard deduction is $8,240 joint plus $700 for each spouse 65 or older, and both apply before any tax is figured. A couple both over 65 can draw $27,960 of IRA and private pension income on top of unlimited Social Security and still owe nothing. Above that, the rate is 5.2% until taxable income passes $46,000.

What comes off, and where

The subtraction on line A10 is of the federally taxable amount, not the gross benefit. If $35,700 of a $42,000 benefit is taxed federally, $35,700 is in AGI and $35,700 comes off. Either way the Kansas tax on it is zero.

Why KPERS is exempt. A state or school employee’s KPERS contributions are taken out of federal wages before tax, but Kansas adds them back on Schedule S line A2 every working year. Having taxed the money going in, Kansas leaves the pension alone coming out. A KPERS retiree who still has a few months of contributions in the retirement year enters them on A2 and the benefits on A14 in the same return.

What the public-pension list does not cover. A pension from a Kansas city or county that is not in KPERS or one of the named systems, a pension from another state’s government, or a pension from a private employer is taxed in full, even if the work was public service. A 457 deferred-compensation plan from a Kansas public employer is taxed too; the exemption is for the retirement systems named in the booklet, not for every dollar a public employee set aside (verify 457 treatment).

Roth conversions: taxed now, free later

A Roth conversion is a distribution from a traditional IRA, reported on federal line 4b, and Kansas taxes IRA distributions in full. So a conversion costs Kansas tax in the year it is done: $520 per $10,000 in the 5.2% bracket, $558 per $10,000 at 5.58%. The payoff is that qualified Roth withdrawals later never enter federal AGI and therefore never reach the K-40, which is worth 5.2% to 5.58% a year for life on top of the federal saving. For a Kansas retiree, the conversion is a genuine two-level decision: the state cost is modest next to the federal, but it is real.

Two Kansas side effects need watching. First, a conversion raises Kansas adjusted gross income, and since 2025 Kansas AGI is the household-income test for the senior property tax freeze (K-40SVR), with a $58,041 limit for the 2025 claim year. A conversion that pushes a couple over the line costs them that year’s freeze refund. Second, because Kansas taxes the conversion but not Social Security, a couple with large Social Security and a small IRA can often convert within the $27,960 of exemption and deduction room each year and pay Kansas nothing at all. The federal side, including Medicare premiums two years later, is in Roth IRAs and the backdoor Roth and IRMAA.

The federal senior deduction, and why it does not help here

The $6,000 federal deduction for people 65 and older, in effect for 2025 through 2028, comes off after adjusted gross income, alongside the standard deduction. Kansas starts from AGI. The deduction never reaches the K-40, and no add-back is needed because nothing was taken out. The same is true of the extra federal standard deduction for age. What Kansas gives for age is its own: $700 more standard deduction per spouse at 65 on a joint return ($850 single or head of household), worth $36 to $47 of tax apiece, and the exemption of Social Security itself, which for most retirees is worth far more than any deduction.

Kansas itemizing for a retiree

Retirees are the people most likely to gain from a Kansas quirk. Kansas lets you itemize on Schedule A even if you took the federal standard deduction, and Kansas itemized deductions are 100% of four items: medical expenses over 7.5% of federal AGI, charitable gifts, mortgage interest and property taxes. Medical expenses include Medicare Part B and D premiums, Medicare supplement premiums, long-term care insurance and the IRMAA surcharge. A couple with $12,000 of medical costs, $3,000 of property tax and $3,000 of gifts on $50,000 of AGI has $8,250 of medical over the floor plus $6,000, or $14,250, against a $9,640 standard deduction. Few self-prepared Kansas returns check.

Property tax relief: three refunds, one claim

Kansas does its real work for older homeowners outside the income tax, through three refund programs run by the Department of Revenue. They are claims, not deductions, filed between January 1 and April 15 after the year (2026 claims from January 1 to April 15, 2027), free through Homestead WebFile, and a claimant may receive only one of the three. All three require a home appraised at $350,000 or less. The income limits below are for the 2025 claim year; the 2026 limits are to come when the Department publishes the 2026 homestead booklet.

“Household income” means different things on different forms. For K-40SVR it has meant Kansas adjusted gross income since the 2025 claim year, so Social Security does not count. For K-40H and K-40PT the older, broader definition still applies and Social Security is counted (verify). Kansas WebFile will work out which of the three pays the most.

The freeze works like this. The base year is the year before you first qualify, deemed 2021 at the earliest, and the refund each year is the amount by which the current property tax on the home exceeds the base-year tax. A homeowner who turned 65 in 2024 has a 2025 base year and files the first K-40SVR for 2026. The home must have been appraised at $350,000 or less in the base year. Any refund goes first against delinquent property tax. A new home starts a new base year.

Separately, and automatically, every Kansas home gets the first $75,000 of appraised value exempt from the statewide 20-mill school levy. That shows up on the county tax bill with no claim to file.

Estate tax, inheritance tax, and the intangibles tax

Kansas has had no estate tax for deaths since January 1, 2010, and no inheritance or gift tax, so only the federal exemption matters to a Kansas family. Inherited IRA withdrawals are taxed by Kansas in full, like any IRA; an inherited KPERS or federal survivor benefit is subtracted on A14. A few counties, cities and townships levy a local intangibles tax on interest and dividends, filed on Form 200 with the county clerk. It exempts IRA and retirement-plan earnings and U.S. and Kansas bonds, and a $5,000 exemption applies to low-income seniors; most retirees live where it is not levied at all.

Withholding and estimated payments

Payers rarely withhold Kansas tax from IRA distributions or private pensions, and nobody withholds on a Roth conversion or a brokerage account. A retiree whose income is Social Security and a public pension owes nothing and needs no estimates. A retiree living on IRA withdrawals and a private pension usually does: estimates are required when the Kansas tax expected after withholding and credits is $500 or more, on Form K-40ES by April 15, June 15, September 15 and January 15, with the same 90%-of-this-year or 100%-of-last-year safe harbor as the federal rules and the penalty on Schedule K-210. Asking the IRA custodian to withhold Kansas tax, or paying the Kansas tax out of the fourth-quarter withdrawal, is the simple fix.
