Does Missouri Tax Your Retirement Income?
It depends on the source, and the picture has been getting better for retirees. Missouri has been phasing out state tax on Social Security benefits and public pension income for many filers in recent years, under updated state law that moves more retirees toward paying no state tax on those income sources at all.
401(k) and traditional IRA withdrawals still generally fall under Missouri's regular progressive income tax, which tops out near 4.95%. That's a real difference from a state with zero income tax, but the gap has narrowed as Social Security and pension exemptions have expanded. Rules here have shifted more than once recently, so specific income thresholds and eligibility are worth checking directly with the Missouri Department of Revenue rather than relying on an older figure.
This calculator projects how your current savings and monthly contributions grow by the time you retire. USACalculator built the Missouri version to pair that projection with the state's evolving tax treatment, so you're planning around a realistic picture rather than an outdated assumption.
Using the Calculator
Enter your current age, planned retirement age, existing savings, monthly contribution, and expected annual return. The dashboard shows your projected balance at retirement, an estimated monthly income based on the 4% withdrawal rule, and how much of your final balance came from contributions versus growth. Pair the result with our Missouri Paycheck Calculator to see how much room your current budget has for boosting contributions.
How the Calculation Works
The calculator compounds your existing savings and monthly contributions forward at your expected annual return until your retirement age, using a standard future value formula. The 4% rule then estimates a sustainable first-year withdrawal amount, a widely used starting point for retirement income planning rather than a guarantee.
Missouri-Specific Retirement Information
Social Security: Increasingly Tax-Free
Missouri has moved toward exempting Social Security benefits from state tax for a growing share of retirees in recent years. Because thresholds and eligibility rules have been updated more than once, it's worth confirming your specific situation with the Missouri Department of Revenue rather than assuming a past year's rule still applies.
Public Pensions: A Similar Trend
Public pension income has followed a comparable path, with recent state law phasing out state tax for many recipients. This is a genuinely positive shift for retired teachers, state employees, and other public pension holders, though exact eligibility still depends on current-year thresholds.
401(k) and IRA Withdrawals
Unlike Social Security and public pensions, withdrawals from a 401(k) or traditional IRA generally fall under Missouri's regular progressive income tax, topping out near 4.95%. This is the piece of retirement income least affected by the state's recent retiree-friendly changes.
Estate and Inheritance Tax
Missouri charges neither a state estate tax nor an inheritance tax, which matters for retirees thinking about what they pass on. Federal estate tax rules can still apply to very large estates, but that threshold is high enough that most households never reach it.
Why Missouri Residents Use This Calculator
People approaching retirement use it to see if their current savings rate is on track. Retirees weighing whether to stay in Missouri or relocate use it to compare the state's improving tax treatment of Social Security and pensions against a no-tax state's flat advantage. Anyone weighing a bigger 401(k) contribution against paying down debt runs the projection here, then checks their Debt Payoff Calculator to compare the two paths side by side.
Common Mistakes to Avoid
- Assuming Missouri taxes all retirement income the same way. Social Security, pensions, and 401(k) withdrawals are treated differently.
- Relying on an old rule about Social Security taxation that no longer reflects current Missouri law.
- Treating the 4% rule as a fixed guarantee rather than a planning starting point.
- Underestimating how much monthly contributions compound over a long working career, even at modest amounts.
