Shawnee, KS
Retirement Planning in Shawnee
You worked one job in Shawnee and ended up with three plan sponsors. Bayer's animal health business sold to Elanco in 2020, then the Shawnee plant sold again to TriRx, with roughly 350 employees transferring each time. Pair that with a Shawnee Mission district pension and you've got a mess of balances from sponsors that no longer exist. Sorting out which is which is where planning starts.
Why Shawnee
Planning built for Shawnee retirees
Johnson County · about 20 minutes northwest · Shawnee Mission Parkway at Nieman
Elanco completed its acquisition of Bayer Animal Health on August 1, 2020, in a $6.89 billion deal: $5.17 billion in cash plus 72.9 million Elanco shares. Employees who stayed through it may hold Elanco stock they did not select. When the Shawnee plant later went to TriRx, roughly 350 employees changed employer again.
The other half of Shawnee is public. Shawnee Mission USD 512 serves the city with about 3,500 employees, all of them KPERS members. Kansas exempts KPERS benefits from income tax outright, while the 403(b) sitting alongside that pension is fully taxable. Two accounts, two entirely different withdrawal answers.
Shawnee's employer history is the reason a plan here starts with an inventory of sponsors rather than an inventory of accounts. Each card describes a documented change and what it leaves behind in a household's balance sheet.
Elanco (former Bayer)
Bayer Animal Health's North American headquarters was in Shawnee. Elanco completed the acquisition August 1, 2020 for $6.89 billion, $5.17 billion cash plus 72.9 million Elanco shares, a stock position many holders did not choose.
TriRx
The Shawnee plant was subsequently sold to the contract manufacturer TriRx, with roughly 350 employees transferring. That is two successive plan sponsors for the same job in about two years.
Shawnee Mission USD 512
About 3,500 employees serving Shawnee, Prairie Village, Mission and Overland Park. All are KPERS members, and Kansas exempts KPERS benefits while taxing the district 403(b) beside it in full.
Kansas Taxes
Kansas tax across Shawnee's changing plan sponsors
Kansas income tax law as of tax year 2026 · verified August 2026
Three sponsors don't create three tax rules. Whatever leaves a 401(k) or an IRA lands in federal AGI, flows into Kansas AGI, and gets taxed in full: K.S.A. 79-32,117 has no subtraction for private plans. A KPERS pension is the opposite, exempt outright under K.S.A. 74-4923(b).
Retiring with your spouse within a year or two of each other? Both Social Security checks are fully exempt since tax year 2024, no income limit. Both IRAs stay fully taxable. Above $46,000 of Kansas taxable income, you pay a flat 5.58% on that half.

Common Questions
Retiring in Shawnee: common questions
Bayer became Elanco, then the Shawnee plant became TriRx. What now?
Start by mapping sponsors to balances. Elanco closed its acquisition of Bayer Animal Health on August 1, 2020 for $6.89 billion, part cash and 72.9 million Elanco shares; the Shawnee plant later transferred to TriRx with roughly 350 employees. What happened inside your specific plan is a question for your plan administrator.
Does the $75,000 school levy exemption cut your Shawnee property tax much?
Not much. Since tax year 2024, $75,000 of appraised residential valuation is exempt from the 20-mill statewide school levy, roughly $172.50 a year at Kansas's 11.5% assessment ratio. Two caveats: it's a fixed dollar amount, so it covers a shrinking share of a rising bill, and K.S.A. 72-5142(b) fixes the rate only through 2026-2027.
You're both retiring within two years. How does Kansas treat two Social Security checks and two IRAs?
The Social Security side is simple: since tax year 2024, Kansas subtracts 100% of what's in your federal AGI, no income limit, for both of you. The IRAs are the opposite: fully taxable, and since the joint top bracket starts at $46,000, nearly all of it lands at 5.58%.
