Tax-Efficient Retirement Income for College Professors: 403(b), 401(a), 457(b) & RMDs

Most retirement-income writing for educators starts with a pension and fits the savings around it. A university career in Kansas or Missouri often does not look like that. Faculty and unclassified staff at Kansas Board of Regents institutions are generally in a mandatory defined-contribution plan rather than KPERS, and academic staff hired since mid-2002 at Missouri's nine regional CURP institutions hold a 401(a)account rather than a formula benefit. When there is no formula, the tax character of retirement income is decided by the retiree - container by container, year by year.

This article is aimed at university and college faculty aged 50 and over in Kansas and Missouri who hold institutional403(b) or 401(a) balances, perhaps a voluntary 457(b), one or more IRAs, and the prospect of consulting or royalty income after leaving the classroom. It explains how each container is taxed at distribution, the ordering concepts that connect them, how Required Minimum Distributions interact with continued academic work, and where consulting income creates tax obligations of its own. It does not decide whether a balance should be annuitized - that decision has its own article in the related reading.

The higher-education account stack, and how each container is taxed

A faculty member's retirement dollars typically sit in four kinds of container: an institutional employer plan - a403(b) at the six Kansas Board of Regents universities, a 401(a) under the College and University Retirement Plan (CURP) at Missouri's nine regional institutions, or the University of Missouri System's own hire-date-tiered program; a voluntary 403(b) or governmental 457(b); IRAs; and often self-employment income. Each is taxed on its own terms.

The employer plan is usually pre-tax. Under the KBOR Mandatory Retirement Plan, the employee's 5.5% and the employer's 8.5%go in before tax, and Internal Revenue Service (IRS) Publication 575 treats payments as fully taxable where the retiree "didn't pay anything or aren't considered to have paid anything" for them. CURP's employer contribution of 6% (and, for employees hired on or after July 1, 2018, the 2% employee contribution) is generally expected to follow the same logic - confirm the tax character of the employee portion with TIAA or the campus benefits office. Distributions are ordinary income federally; the state layer differs by residence and, in Kansas, by plan type.

A governmental 457(b) has a distinctive tax personality. The 10% additional tax on early distributions under Internal Revenue Code Section 72(t) generally does not apply to distributions from a governmental 457(b) plan (the exception is set out in IRS Publication 575 and the Form 5329 instructions) - except for amounts rolled in from a 403(b),qualified plan, or IRA, which keep their original character. A voluntary 403(b)reaches similar territory only through the age-55 separation-from-service exception described in Publication 575.

Designated Roth accounts - offered in the KBOR Voluntary Retirement Plan and in other voluntary plans that provide for them - invert the timing: qualified distributions come out free of federal income tax, and Roth 401(k)/403(b) accounts carry no lifetime RMDs from the2024 distribution year (for a governmental 457(b) Roth account, confirm with the plan administrator).

Ordering concepts: a framework adapted for faculty

The sequencing framework in the companion article on building a retirement paycheck starts from a pension floor and asks what the accounts must do around it. For faculty in defined-contribution plan sit needs adapting: there may be no floor unless one is built - by annuitizing part of a balance, by Social Security, or both - and the accounts must do all the work a pension would have done. Their drawing order shapes the tax on every year.

Three ordering concepts recur. First, bracket-aware timing: because pre-tax withdrawals are ordinary income, the years between leaving the university and the start of Social Security or RMDs are years in which the retiree, not the statute, decides how much taxable income to create. Second, container-matching: a governmental 457(b) can carry the early years without the 10% additional tax, a 403(b) can after separation at 55 or later, and Roth balances can be held back for high-income years. Third, the annuity layer: where part of a balance has become a lifetime annuity - the decision the related article on faculty annuitization examines - those payments arrive as ordinary income on a fixed schedule and Publication 575addresses minimum distributions from an annuity plan - annuity payments under the plan generally count toward the requirement for that annuitized portion; how the plan treats any remaining balance is a plan-administrator question.

Roth conversion belongs here as a neutral concept, not a recommendation. Converting pre-tax dollars to a Roth account makes the converted amount taxable in the conversion year in exchange for tax-free qualified distributions later. Whether that trade suits a household depends on the bracket in the conversion year, the expected bracket later, the state of residence in each, the effect on the taxable share of Social Security, and whether the tax can be paid from outside the account - questions for an adviser and a CPA or Enrolled Agent with a real return in front of them.

RMDs when the professor has not quite retired

Required Minimum Distributions begin at 73for those born 1951 through 1958 and at 75 for those born in 1960 or later; for1959 births the position is unsettled, with proposed rules pointing to 73. The still-working exception lets a participant delay RMDs from the current employer's plan until the year of retirement - only that plan, only where it allows, never an IRA. For faculty phasing out through emeritus or part-time appointments, that exception is the pivot.

Academic careers rarely end on a single day. An emeritus professor still on the payroll of the same institution may be able to defer RMDs from that institution's plan, while RMDs from a prior university's plan and from every IRA proceed on the statutory schedule. Whether a phased or emeritus arrangement counts as continued employment is a plan-document question - ask the campus benefits office, in writing, before assuming either answer.

Three further rules matter. The first RMD may be deferred to April 1 of the following year, but each later RMD is due by December 31 - so deferring the first puts two taxable RMDs into the second year. Aggregation is container-specific: IRA RMDs may be taken from any IRA and403(b) RMDs from any 403(b) contract, but a 401(a) or 457(b) RMD must come from that plan itself; a missed RMD carries a 25% excise tax, reduced to 10% if corrected within two years. And long-tenured faculty with pre-1987 403(b) balances should ask whether the plan separately accounts for them - if so, those amounts need not be distributed until December 31 of the year the participant turns 75(or, if later, April 1 of the year after the participant retires); if not, the whole balance follows the age-73 rules.

Consulting, emeritus, and royalty income: the self-employment touch points

Post-retirement consulting, contract teaching, or research income is usually taxed twice: as ordinary income and - where net earnings from self-employment reach $400 or more in a year - under the self-employment tax, which the IRS describes as "12.4% for Social Security and 2.9% for Medicare taxes." The amount subject to it is generally 92.35% of net earnings; half the tax is deductible in figuring adjusted gross income; the Social Security portion stops at the wage base($184,500 for 2026).

An Additional Medicare Tax applies above $200,000 ($250,000 on a joint return). Whether a textbook or licensing royalty stream is self-employment income depends on how it arose and whether it reflects an ongoing trade or business - a characterisation question for a CPA or Enrolled Agent, case by case. Self-employment income also opens a door: any self-employed individual can establish a Simplified Employee Pension (SEP),with contributions limited to the lesser of 25% of compensation (net earning sunder Internal Revenue Code Section 1402(a), with a special self-employed calculation) or an indexed annual cap - a further pre-tax container, with its own RMD and ordering questions.

The practical point is coordination. Consulting income raises the bracket into which every other withdrawal lands, can push more Social Security into taxable income under the combined-income rules ($25,000 single / $32,000 joint for the 50% tier; $34,000 / $44,000 for the 85% tier - thresholds that are not indexed), and brings estimated-tax obligations a salaried career never required.

The state layer: a Kansas detail faculty should not miss

Kansas does not exempt 403(b), 457(b), or IRA withdrawals from state income tax — with one exception directly relevant to Regents faculty. The Schedule S line A14 subtraction list includes "income from retirement annuity contracts purchased for faculty and others employed by the State Board of Regents or by educational institutions under its management." Ordinary K-12 403(b) withdrawals are not on that list. Which distributions qualify is a question for the campus and a Kansas tax professional.

Kansas also fully exempts Social Security benefits from state tax for tax years beginning after December 31, 2023 under K.S.A. 79-32,117(c)(xviii)(B).

Missouri treats 403(b), 401(k), and IRA distributions as ordinary income, with a private-pension exemption of up to$6,000 per taxpayer available only within Missouri adjusted-gross-income limits; the Social Security deduction is 100% for taxpayers aged 62 or older by December 31. Whether a public-university defined-contribution distribution qualifies for Missouri's public-pension deduction is a question for a Missouri tax professional with the plan documents. And under 4 U.S.C. § 114, only the state of residence may tax retirement income, so retiring across the state line changes the state answer entirely - the companion article on reducing taxes in retirement works through that flip.
