The All-Pretax Problem

Real Conversations

Here's a pattern from my calls with real people planning retirement, and it might be the most common single finding across all of them. (Details changed and blended throughout so nobody is identifiable.)

A diligent saver in his 50s shares his numbers. Strong balance, built through decades of automatic 401k contributions, raises directed straight into the plan, employer match captured every year. Textbook behavior. Then we look at WHERE the money lives: 95-plus percent pretax Traditional, a sliver of Roth, modest cash.

And then he says some version of the sentence I've now heard many times: "I'm starting to worry about what happens when I have to take it out."

He should. Not panic. Worry productively. Because the all-pretax portfolio is the tax bomb you build by following every piece of standard advice.

How the bomb assembles itself

Nobody chooses 97% pretax. It accumulates. The 401k was the default account, the deduction felt like winning every April, Roth options didn't exist early in his career and felt "expensive" later, and the match went to Traditional automatically. Thirty years of sensible individual decisions, one collective outcome: nearly every retirement dollar he owns carries an unpaid tax bill, and the IRS holds the schedule.

These letters have covered each fuse separately. Now watch them connect on one household:

Every dollar out is ordinary income. RMDs force the withdrawals at 73 or 75 whether he needs them or not, on balances that will have doubled again by then. The forced income fires the tax torpedo on their Social Security and can cross IRMAA cliffs. If he dies first, his wife inherits the entire bomb as a single filer at compressed brackets (the widow's penalty, and yes, he asked about exactly this on the call). And whatever remains lands on the kids inside ten years, taxed at THEIR peak-career rates. One account type. Five downstream collisions.

The bitter irony: the deduction he collected at 22-24% during his career is scheduled to be repaid at equal or higher rates, by him, his widow, or his children. The deferral was never a discount. It was a loan.

Defusing at 56 versus 66

The fix is no mystery to readers of these letters: systematically move money from the pretax pile to Roth and taxable at controlled rates, using every low-income year available. What changes with age is how much runway exists.

At 56, still working, the moves are structural: shift NEW contributions toward the Roth 401k (the current deduction at peak earnings is tempting, but he's feeding the bomb), build the taxable and cash buckets that will fund the gap years, and map the future windows: any layoff year (the Rule of 55 letter), the retirement-to-Social-Security gap, the pre-RMD years. A 56-year-old aiming at 63 with RMDs at 75 has potentially a DOZEN conversion years ahead. That's enough runway to move seven figures at 12-22% instead of surrendering it at 24-32%.

At 66, retired, the same math with less runway and more cliffs: seven-ish years to RMDs, IRMAA already watching (the two-year lookback started at 63), and conversions throttled under the tiers. Still enormously worth doing. Just worth doing SOONER, which is the entire moral of the Golden Window letter and the reason this one exists.

The reframe

Here's what I tell every all-pretax saver, because the emotional note matters as much as the math: the balance is real, the discipline was real, and nothing is broken that a decade of deliberate repositioning can't largely fix. The account TYPE is the problem, not the saving. He didn't do it wrong. He did it in the only account anyone offered him, and now the second half of the game is getting it out as skillfully as he put it in.

The first half of retirement planning is accumulation. Almost everyone plays it. The second half is location. Almost nobody does, and it's worth nearly as much.
