The RMD Problem: How 401(k) Required Minimum Distributions Can Raise Taxes — and What Utah Workers Should Do Now
A 401(k) offers tax-deferred growth and employer matches, but traditional accounts face required minimum distributions (RMDs) beginning at age 73. Those mandatory, taxable withdrawals can raise retirees’ taxes, affect benefits, and complicate long-term retirement planning.
- RMDs are taxable: mandatory withdrawals can push retirees into higher tax brackets and affect Social Security and Medicare costs.
- Roth conversions and strategic pre-RMD withdrawals are common tools to manage future tax exposure.
- Plan early: check employer plan rules, model projected RMDs, and time conversions during low-income years.
- Local impact: Utah workers should consider state and federal interactions and consult local advisors to preserve after-tax retirement income.
Why RMDs matter
A traditional 401(k) gives you a tax break when you put money in. The money grows without taxes until you take it out, which is useful while working. But the IRS requires you to start taking money out at a certain age — those required minimum distributions (RMDs) are taxable. If your account is large, RMDs can add a significant amount of taxable income in a single year.
RMD ages and penalties
Current guidance sets the RMD starting age at 73 for many savers, though prior laws and potential future changes affect other birth years. Failing to withdraw the required amount can trigger a steep penalty; past guidance illustrated a 50% excise tax on any shortfall, making compliance essential.

How RMDs affect taxes and other benefits
- Tax brackets: RMDs count as taxable income; large withdrawals can push you into a higher federal (and state) tax bracket. Fidelity
- Social Security: Higher combined income from RMDs can make more of your Social Security benefits taxable, reducing after-tax benefit value. Fidelity
- Medicare premiums: Income-related Medicare surcharges (IRMAA) tie to reported income; larger RMDs can raise Medicare Part B and D premiums. Fidelity
Why the size of your 401(k) matters
Steady contributions and decades of investing can grow a traditional 401(k) to several million dollars. That growth is positive, but it also means future RMDs may be large. If you don’t need the forced withdrawals for living expenses, they become taxable events that reduce flexibility and can affect inheritance plans.
Options to reduce RMD risk
Roth conversions
Converting some or all of a traditional 401(k) to a Roth vehicle during lower-income years is a common strategy. Money in a Roth IRA is withdrawn tax-free in retirement and is not subject to RMDs, which can shrink future taxable income and reduce the chance that mandatory withdrawals will bump you into higher tax rates. See guidance from Fidelity.
Strategic withdrawals before RMDs start
If you expect a low-income gap — for example, between leaving work and starting Social Security — that period can be a smart time to take withdrawals from a traditional 401(k). Those withdrawals may be taxed at a lower rate now than RMDs would be later. Partial Roth conversions during low-income years can help “fill up” lower tax brackets without pushing you into a higher one. See Fidelity and T. Rowe Price.
Keep saving in 401(k)s — but plan for the long term
A 401(k) remains one of the best tools for retirement thanks to payroll convenience, tax deferral, and employer matches. Experts note the plan’s strengths while warning about the RMD downside. Continue claiming employer matches while you work, then plan how to manage that balance before RMDs begin. See Fidelity, ICI, John Hancock, and Empower.
Practical steps for savers
- Check your employer plan rules. Some plans limit in-plan Roth conversions or restrict rollovers while you’re employed; know your options. Fidelity
- Look at projected RMDs. Use a calculator or work with an advisor to estimate future taxable income from RMDs.
- Time conversions and withdrawals. Plan around low-income years and convert only enough each year to avoid moving into a higher bracket.
- Watch interactions with Social Security and Medicare. Reported income affects benefit taxation and Medicare premiums; small changes can have outsized effects.
- Keep claiming employer matches. The match is free money that builds your nest egg. John Hancock, Empower

Implications for Utah
Economic impact
Utah workers who build large 401(k) balances could face higher federal tax bills once RMDs start, reducing after-tax income for retired Utahns and altering household retirement budgets. For savers who rely on every dollar, planning to manage or shrink future taxable withdrawals can preserve more of the nest egg.
Political consequences
Conservative Utah voters often favor policies that reduce tax burdens and preserve individual control over retirement savings. Strategies like Roth conversions and strategic withdrawals align with those priorities by offering legal ways to lower lifetime taxes and limit government claims on retirement income, which may increase demand for local guidance.
Social effects
Utah’s culture of family support and early saving means many are disciplined savers, but even they can be surprised by RMD-driven tax bills late in life. That could force changes to withdrawal timing, inheritance plans, or reliance on other assets. Employer, credit union, and community education programs can help older workers avoid unnecessary tax hits.
Cultural relevance
Utah’s conservative, self-reliant values favor practical, do-it-yourself approaches to finances. Teaching straightforward 401(k) tax planning — such as timing Roth conversions during low-income years — fits that value set by helping people retain more of what they earned.
Practical applications for Utah workers
- Meet with a tax advisor who understands federal RMD rules and Utah tax treatment of retirement income to model scenarios that matter to you.
- If you expect a low-income gap before Social Security, plan conversions and withdrawals in those years to use lower tax brackets.
- Check your company plan for Roth conversion options and rollover rules; if limited, consider rolling funds into a Roth IRA after leaving the job.
- Continue taking full employer matches while working — the match is an immediate return few other investments offer. John Hancock, Empower
