Roger Whitney to 60-Year-Old With $3.5M: ‘Continue to Save in Your Roth 401(k) and Use Your After-Tax Cash’

A 60-year-old caller named Sue wrote into the Retirement Answer Man podcast with a question that might sound mundane but ranks among the most consequential decisions a pre-retiree can make.

She and her husband hold just under $3.5 million across their accounts: $2.1 million pre-tax, $1.3 million taxable, $80,000 in Roth savings, and $300,000 in cash. Sue is still working and plans to retire at 62. Before she does, she wants roughly $100,000 for home projects.

Her instinct, in her own words: “I would like to stop saving for retirement and use the cash for projects around the house. About $100,000 before I retire.” The plan: stop Roth 401(k) contributions, let each paycheck rebuild the cash account, and fund the renovations without touching the $300,000 reserve.

Roger Whitney told her to do the opposite. Keep maxing the Roth 401(k). Spend the cash.

The verdict: Whitney is right, and the margin isn’t close

Roger Whitney, CFP®, CIMA®, CPWA®, RMA, has spent more than 30 years walking clients into retirement and has hosted the Retirement Answer Man podcast for well over a decade. The show has surpassed 9 million downloads. This is exactly the kind of counterintuitive call that separates planners who think in tax buckets from those who simply track account balances.

His reasoning centers on what financial planners call optionality. Two pools of money can each fund a kitchen remodel, but they are not interchangeable on the back end. Cash in a savings account carries no special tax status. Roth 401(k) contribution room, once skipped, vanishes forever. There is no going back next year to reclaim this year’s contribution space.

Here is how Whitney framed the do-over button: “If you use your $100,000 in after-tax cash and you continue to save in your Roth 401(k), and say 3 years from now you realize, wow, we don’t have as much cash as we needed in our cash reserves, you can always take the money from your Roth.”

And the cost of taking Sue’s original approach: “Whereas if you stop saving in your 401(k) in order to preserve your cash, you lose that option on the money that could have been growing tax-free forever.”

Walking through the math

Picture two paths over the next two years until Sue retires at 62.

Path A (Sue’s instinct): Stop contributing. Direct that money into cash. Pay for the home projects from new savings. End state: $300,000 cash mostly intact, with the Roth 401(k) capped at whatever Sue had contributed before this year. The forgone Roth contributions never compound tax-free.

Path B (Whitney’s call): Keep maxing the Roth 401(k). Pull $100,000 from the $300,000 cash pile for the renovations. End state: $200,000 cash remaining, plus two additional years of Roth contributions compounding tax-free for the rest of her life.

For 2026, Sue can contribute up to $35,750 if her plan offers the super catch-up provision for ages 60 to 63. That total combines the $24,500 base limit with the $11,250 super catch-up, which replaces (rather than stacks on top of) the standard $8,000 catch-up available to savers 50 and older. If everything goes to plan and the $200,000 cash cushion holds, the Roth money never gets touched and grows untaxed indefinitely. If cash runs short in retirement, Sue is already past age 59.5, and as long as her Roth 401(k) satisfies the 5-year rule, qualified withdrawals come out entirely tax-free. The Roth is functioning as both a retirement account and a backup cash reserve. Cash, by contrast, can only ever be cash.

The variable that changes the answer

The entire calculus rests on whether Sue can actually reach the Roth money without penalty when she needs it. For a 60-year-old, the two relevant tests are age 59.5 (already cleared) and the 5-year rule on the Roth 401(k) itself. Sue has only recently started maximizing her Roth 401(k) contributions because her Roth balances are so low. If the account is brand new this year, the clock matters.

Unlike a Roth IRA, each Roth 401(k) has its own 5-year seasoning period. Rolling it into a Roth IRA she has held for more than five years before tapping the funds is one workable solution. Waiting until the account itself crosses the 5-year mark is the other. Once both conditions are satisfied, qualified withdrawals emerge tax-free and penalty-free.

For a saver still under 59.5, the math flips entirely. Locking $100,000 into a Roth 401(k) and then needing it for a roof repair in two years means navigating a hardship withdrawal, a 401(k) loan, or penalties. Cash wins in that scenario. For Sue, age has already unlocked the door.

Why 2026 makes this decision even more compelling

A SECURE 2.0 Act rule took effect January 1, 2026, with real teeth for high earners. Workers age 50 or older who had more than $150,000 in prior-year FICA wages from their plan-sponsoring employer must now route all catch-up contributions into a Roth 401(k), with no pre-tax option available. The Treasury and IRS published the final regulations on this provision on September 16, 2025. Then, on November 13, 2025, IRS Notice 2025-67 raised the FICA wage threshold from $145,000 to $150,000 before the rule took effect. The $150,000 figure is based on Social Security wages reported in Box 3 of the W-2, not total compensation.

If Sue’s 2025 FICA wages exceeded that level, her catch-up dollars are already required to go into the Roth. Whitney’s advice, in that case, aligns perfectly with what the tax code now mandates.

Even if Sue’s income fell below the $150,000 threshold, the optionality argument holds on its own. The SECURE 2.0 provision simply reinforces the point: Roth contribution room is a perishable, high-value asset, and it matters most for someone just two years from retirement who has barely any Roth savings to show for a decades-long career.

What to actually do with this

1. List every pool of money you hold, sorted by tax treatment: pre-tax, Roth, taxable, cash. Sue’s split of $2.1 million pre-tax, $1.3 million taxable, $80,000 Roth, and $300,000 cash tells the story at a glance. She is Roth-starved and cash-heavy, which is precisely why redirecting cash toward home projects while preserving contribution room makes so much sense.
2. Confirm your Roth 401(k)’s start date and your current age. Past 59.5 with the 5-year clock running (or satisfied via rollover into an older Roth IRA), the account doubles as an emergency backstop. Below that age, the analysis changes significantly.
3. Before cutting contributions to free up cash, ask one question: does the cash you already hold cover the goal? If yes, the contribution room is worth more than the liquidity buffer you would rebuild by stopping contributions.
4. Treat each year’s contribution limit as a perishable asset. Unused room expires at December 31 and never returns. For 2026, that means up to $24,500 in base contributions, plus $8,000 in standard catch-up for those 50 and older, or $11,250 in super catch-up for those 60 to 63. A Roth IRA, for those who qualify at their income level, allows a total contribution of $8,600 for savers 50 and older in 2026, combining a $7,500 base with a $1,100 catch-up that is now indexed for inflation under SECURE 2.0.

Tax-advantaged contribution room is the rare financial asset that comes with a hard expiration date. Spending cash you already hold is reversible. Skipping a Roth contribution year is not.

Editor’s note: This pass corrected the 2026 Roth IRA limit for savers age 50 and older from $7,500 to $8,600 (a $7,500 base plus a $1,100 catch-up now indexed for inflation under SECURE 2.0), expanded Roger Whitney’s listed credentials to include CIMA®, CPWA®, and RMA alongside his CFP® designation, and replaced the approximate “late 2025” timing of the SECURE 2.0 catch-up rule with specific dates: final regulations published September 16, 2025, and IRS Notice 2025-67 on November 13, 2025 raising the mandatory Roth catch-up FICA threshold from $145,000 to $150,000.
