Why His $80,000 Retirement Withdrawal Is Subtly Pulling His Social Security Into the Tax Torpedo

Picture a 68-year-old who retired last year with roughly $1 million in a traditional, pre-tax 401(k). He listens to Dave Ramsey, sleeps better for it, and follows the host’s well-known math: pull 8% a year, or about $80,000, and let the rest keep compounding. His Social Security check arrives on the third Wednesday of every month. On paper, the plan looks airtight.

The appeal is obvious. On The Ramsey Show episode You Can’t Win With Money if You Don’t Know Where Your Money Is (Nov. 2, 2023), Ramsey put it plainly: “If you make 12 and you need to leave 4% in there for inflation… that leaves you 8. So I’m perfectly comfortable drawing 8.”

In the next breath, he offers a softer version: “But if you want to be a little bit conservative. Seven.” He is openly rejecting the 3% and 4% to 5% camps, the more conservative withdrawal rate camps.

On the April 12, 2023 episode ‘The Tenants Pay My Mortgage’ Is Bullcrap! (Hour 2), he framed the dollars: “If you’ve got a million dollars and you’re pulling off 8%, that’s 80,000 bucks a year.” He even concedes the draw “might or might not have kept up with inflation.” On No One Accidentally Wanders Into the Land of Success (June 25, 2024), the imagery sticks: “The goose just keeps laying the eggs.”

That formula accounts for returns and inflation. It leaves out taxes. For a retiree whose money sits in a pre-tax account, that omission has a name: the Social Security tax torpedo.

The piece of the math Ramsey skips

Every dollar pulled from a traditional 401(k) lands on the tax return as ordinary income. That matters because of how Social Security itself gets taxed. The IRS uses provisional income: adjusted gross income (AGI), plus tax-exempt interest, plus half of your Social Security benefit.

For a single filer, once provisional income crosses $25,000, up to 50% of benefits become taxable. Above $34,000, up to 85% of benefits become taxable. Those thresholds have been frozen since 1984, so almost any retiree taking an $80,000 pre-tax withdrawal sails past them. The 85% figure is the share of the benefit pulled into taxable income, not the tax rate.

The second hit arrives two years later in the Medicare mailbox. IRMAA, the income-related surcharge on Medicare Part B and Part D, kicks in once modified adjusted gross income (MAGI) tops $109,000 for a single filer or $218,000 for a couple in 2026. Crucially, 2026 premiums are based on the 2024 tax return. A big withdrawal today can quietly raise your Medicare premium in 2028. The same $80,000 pulled from a Roth instead? None of this happens. Roth dollars do not count as taxable income, do not feed provisional income, and do not push MAGI toward an IRMAA bracket.

How the pieces actually fit together

Ramsey’s underlying point deserves credit. Running out of money is a real risk, and a 3% draw on a million dollars is often too cautious for a healthy 68-year-old. Sequence-of-returns risk, the danger of a bad market in the first few retirement years, is the bigger early threat than taxes. But none of that erases the tax bill on a pre-tax-only strategy.

The smarter version blends three buckets: pre-tax (401(k), traditional IRA), Roth, and taxable brokerage. Pulling some from each lets a retiree control provisional income and MAGI year by year. Roth conversions done in lower-income years, often the gap between retirement and age 73 required minimum distributions, can shrink the future pre-tax balance before it becomes a forced taxable event. The 2.8% Social Security cost-of-living adjustment for 2026 helps with prices, but it also nudges more retirees over those frozen 1984 thresholds every year.

Plug in your own benefit and withdrawal to see how much of the check the IRS would claim back.

What to take from this

Two things are worth sitting with before following any 8% rule of thumb:

1. The withdrawal rate overstates after-tax income. An $80,000 pull from a pre-tax 401(k) lands on the return as $80,000 of ordinary income, which can drag up to 85% of your Social Security into the taxable column and bump your Medicare premium two years out. Run the number after taxes before you build a budget around it.
2. The hardest mistake to undo is account mix. If everything is pre-tax at 68, every withdrawal pulls the tax torpedo lever. Partial Roth conversions in your 60s, done deliberately and modestly, give you tax-free dollars to blend in later. That flexibility is worth more than chasing an extra percentage point of withdrawal.

Ramsey is right that the goose can keep laying eggs. The quieter truth is that the IRS shows up for breakfast, and a tax pro who can model the after-tax draw is usually worth the fee. Your numbers, your benefit, and your state tax rules will shift the picture, sometimes more than you expect.
