How School Administrators Can Reduce Taxes in Retirement

Tax in retirement is not one question but several stacked on top of each other: what the federal government taxes, what your state of residence taxes, and when each dollar of income arrives. For school administrators - principals, district office leaders, superintendents - the stakes are higher simply because the numbers are: a final-average-salary pension built on an administrator's pay, decades of 403(b) and 457(b) deferrals, and often a working spouse's income alongside.

This article is aimed at Kansas and Missouri school administrators within sight of retirement who want to understand the tax landscape their income will land in. It is tax education, not tax advice: it maps the rules with statute references so the right questions reach a CPA or Enrolled Agent (EA) and a qualified adviser, and it recommends professional involvement throughout. It does not prepare anyone's return, modela specific conversion, or recommend a transaction.

The layers of an administrator's retirement tax picture

An administrator's retirement income is taxed in layers: federal income tax on pension payments and pre-tax account withdrawals as ordinary income; federal taxation of Social Security under its own combined-income rules; and a state layer that depends entirely on the state of residence. The planning content lives in two places - knowing which layer each income source falls into, and controlling, where the rules allow, the timing of the layers you can time.

Kansas and Missouri: what each state taxes

The two states treat the same income sources differently, and neither state's treatment can be assumed from the other. Kansas exempts Kansas public pensions and Social Security entirely but gives no relief on account withdrawals; Missouri runs a capped public pension deduction and an age-conditioned Social Security deduction. The table sets the layers side by side.

Two Kansas details are easy to miss. The KPERS exemption does not extend to KPERS 457 deferred-compensation balances - those withdrawals are fully taxable in Kansas. And the Missouri cap is aper-taxpayer figure with a stated tax year; quoting it without the year, or projecting next year's figure before the Missouri Department of Revenue publishes it, is how errors enter retirement plans.

The state-line wrinkle: residence decides, not where youworked

Under 4 U.S.C. § 114, a federal statute, nostate may tax the retirement income of a person who is not a resident ordomiciliary of that state. The consequence for the Kansas City metro and otherborder households is stark: the tax treatment of a career's pension is decidedby where the retiree lives, not where the career happened.

Concretely: a PSRS pension received by a Kansas resident cannot be taxed by Missouri - but it is fully taxable in Kansas, because the Kansas exempt list names only Kansas and federal plans. AKPERS pension received by a Missouri resident cannot be taxed by Kansas - and Missouri taxes it, less the public pension deduction up to the annual cap. An administrator weighing a retirement move across the state line is therefore weighing a genuine tax variable, in either direction, and one worth quantifying with a CPA or EA before, not after, the move.

The federal layer: Social Security taxation and the senior deduction

Federally, the taxable share of Social Security depends on “combined income” - adjusted gross income plus tax-exempt interest plus half of benefits. Up to 50% of benefits become taxable above $25,000 for single filers and $32,000 for joint filers, and up to 85% above$34,000 and $44,000. Those thresholds are not indexed for inflation, which is why each year more retirees cross them without any change in real income - and why withdrawal timing can move the taxable share in a given year.

Separately, the One Big Beautiful Bill Act created a senior deduction of $6,000 per qualifying individual aged 65 or over($12,000 for a married couple where both qualify) for tax years 2025 through 2028, phasing out above $75,000 of modified adjusted gross income ($150,000joint). It is a deduction in addition to the standard deduction - it does not make Social Security tax-free, and describing it that way overstates what it does. Its interaction with any particular return is a question for a tax professional.

The timing levers - described as categories, not advice

Administrators typically control more income timing than they expect: which accounts are drawn first, whether pre-tax money is converted to Roth in lower-income years, and how Required Minimum Distributions are anticipated. Each lever is a category with trade-offs, not a move to be copied.

Withdrawal order shapes which bracket each year's income lands in; the sequencing framework is covered in the companion retirement-paycheck article. Roth conversions - paying tax now to move pre-tax money into Roth - are a concept with genuine trade-offs in both directions: conversion income is taxable in the year of conversion, can raise the taxable share of Social Security, and trades a known tax bill today against uncertain future brackets. RMDs, currently beginning at age 73 for those born 1951 through1958, eventually force pre-tax withdrawals whether needed or not, which is why the pre-RMD years attract planning attention. And for charitably inclined IRA owners aged 70½ or over, the Qualified Charitable Distribution - up to $111,000per person for 2026, from IRAs only - is a mechanism a CPA or EA can evaluate against ordinary giving.
