A retired law-enforcement officer with $3.4 million in a 457 plan should use the penalty-free years before age 73 RMDs to make bracket-limited Roth conversions, paying taxes from a brokerage account while watching Medicare IRMAA thresholds.

Retiree's $3.4M 457 plan needs bracket-timed Roth conversions before age 73
A retired law-enforcement officer holding $3.4 million in a 457 plan faces a roughly 13-year window to draw down and convert that balance before the IRS forces required minimum distributions at age 73, when withdrawals would stack on top of a $100,000 annual pension and a $20,000 rental income stream.
"The best course of action begins by answering one fundamental question: 'Over the course of my retirement, what do I want my lifestyle to look like?'" said Jonathan Vance, a planner at Vance Financial Planning. Once spending needs are set, he said, it becomes easier to overlay a long-term tax strategy designed to minimize the tax hit on both the retiree and any heirs.
The retiree's income picture narrows the room for maneuvering. Pension income of roughly $100,000 a year plus $20,000 from a rental property already fills the lower tax brackets before a single dollar is withdrawn from the portfolio, said Stoy Hall, a certified financial planner at Black Mammoth. "Convert only up to the top of your current bracket and pay the tax bill out of that $260,000 brokerage account, not out of the converted money," Hall said.
The central planning lever is that a governmental 457 plan carries no 10 percent early-withdrawal penalty once the participant separates from service, at any age. "Rolling it into an IRA is the move that would lock it up until 59 1/2," said Jeffrey Hallman at Citizens Life Group. "Plenty of people roll it out of habit the month they retire and give away the one feature that makes a 457 worth having." Leaving the balance in the 457 lets withdrawals be timed by choice rather than necessity, which is when partial Roth conversions make the most sense, said Mark Sanaiha, a certified financial planner at Macallen Capital.
Filling Brackets, Watching IRMAA
The gap years between retirement and age 73 are the cheapest window to convert or draw down, because income during that stretch is limited to the pension and rental receipts. Converting up to the top of the current marginal bracket each year, rather than in one large lump, spreads the tax liability across multiple low-income years. A higher annual distribution rate also applies downward pressure to future portfolio growth, which can reduce the expected tax impact of later RMDs, Vance noted.
Timing carries a second-order cost. A poorly timed conversion can push income above Medicare IRMAA thresholds and spike premiums two years later, Sanaiha warned. "A Roth conversion that saves you taxes but then triggers IRMAA surcharges would be a tough pill to swallow."
At age 73 the IRS forces distributions from the 457 whether the retiree wants them or not, and those RMDs stack on top of the pension. The retiree's $300,000 Roth IRA and $260,000 brokerage account add further flexibility, with the brokerage serving as the source for conversion tax payments so no converted dollars are consumed by the tax bill.
Building the Advisory Team
The retiree should seek a fee-only fiduciary who does tax planning, ideally pairing a certified financial planner running multiyear tax projections with a CPA who files the return. "One builds the plan, one files it and they talk," Hall said. "If anyone pitches you an annuity before they've looked at your bucket math, walk out." Hourly planners typically charge $200 to $500 per hour, while project-based engagements range from $1,500 to $8,500 depending on complexity.
The strategy hinges on a realistic spending estimate, since that determines both the annual distribution rate and the upper and lower bounds for recommended conversions. Retirement income and tax planning of this kind typically falls within the expertise of a CFP, Vance said, with the retiree's own bracket math and IRMAA position determining how aggressively to convert each year before the RMD clock starts.
