Key Takeaways

  • A single 62-year-old with no other income has to withdraw $51,991 from a pre-tax 401(k) in 2027 to keep $4,000 a month after federal tax.
  • The IRS’s new 2027 figures, a $16,600 standard deduction and a 10% bracket up to $12,800 of taxable income, keep the federal bill to $3,991.
  • At an assumed 4% draw, that withdrawal takes $1,299,773 invested.
  • Before 65, the bigger risk is health insurance: the withdrawal counts toward the income limit of 400% of the poverty line for ACA Marketplace tax credits.

Retiring at 62 means living on your savings for a few years before Medicare, and maybe longer before Social Security. So the first question is how much you need saved, and federal tax is a big part of the answer.

The IRS just made that easier to work out for next year. On Nov. 5, it released its 2027 inflation adjustments, which apply to returns filed in 2028. And for an early retiree living off a 401(k), federal tax takes a smaller bite than you might expect.

A $48,000 year, all from a 401(k)

Let’s take a hypothetical single 62-year-old who has stopped working, with no pension and no Social Security coming in yet. Every dollar they spend in 2027 comes out of a pre-tax 401(k), and the goal is to keep $4,000 a month, or $48,000 for the year, after federal tax. Withdrawals from a pre-tax 401(k) are taxed as ordinary income, so they’ll have to take out more than $48,000 to keep $48,000. How much more depends on two of the figures the IRS just released.

What changes in 2027

For 2027, the standard deduction for a single filer rises to $16,600, up from $16,100 this year. The 10% bracket now runs to $12,800 of taxable income, up from $12,400, and the 12% bracket runs from there to $52,025, where 22% starts. At 62, our retiree doesn’t get the extra deductions the tax code gives filers 65 and older, so $16,600 is the whole deduction. Even so, the first $16,600 withdrawn is tax-free, and the next $12,800 is taxed at just 10%.

It takes $51,991 to keep $48,000

Say our retiree withdraws $51,991 over 2027. Take off the $16,600 standard deduction, and $35,391 is taxable. The first $12,800 of that is taxed at 10%, or $1,280, and the remaining $22,591 at 12%, or $2,711. That’s $3,991 in federal tax, leaving $48,000, or $4,000 a month.

So the IRS gets less than 8 cents of every dollar withdrawn. Under this year’s figures, the same $48,000 would take a $52,068 withdrawal and $4,068 of tax, so next year’s adjustments save this retiree $77. Not life-changing, but welcome.

Funding $51,991 a year with an assumed 4% draw takes $1,299,773 invested ($51,991 divided by 0.04). Call it $1.3 million.

Health insurance is the bigger risk before 65

For a retiree like this one who buys coverage on the ACA Marketplace until Medicare starts at 65, a 401(k) withdrawal can cost far more than its tax. Under the IRS’s rules, the Premium Tax Credit goes only to households with income of at least 100% and no more than 400% of the federal poverty line. Congress lifted the 400% cap only for tax years 2021 through 2025, and as of this week it hasn’t brought that back for 2027. So a household even a dollar over the line gets no credit at all.

Every dollar of that $51,991 counts toward household income for the credit. The dollar line comes from HHS’s poverty guidelines: for 2027 coverage, it’s the guidelines most recently published as of Nov. 1, when open enrollment began. And for tax years after 2025, there’s no cap on repaying advance credits that turn out to be too high. So a retiree who collects the credit all year, then takes a big December withdrawal that pushes income over the line, pays every dollar of it back at tax time.

Which, yikes.

Plan the whole year at once

The tax brackets and the credit’s income test both look at a full year’s income, so it’s worth planning withdrawals by the calendar year. Our retiree’s $35,391 of taxable income sits $16,634 below the 22% bracket, so withdrawals could reach $68,625 in 2027 before a single dollar is taxed at 22%. Check the 400% line first, though, since crossing it costs the whole credit. Before a big one-off withdrawal for a new roof or a car, find out where that line sits for your household. Splitting the purchase across two calendar years keeps each year’s income lower.

Social Security will lighten the load

A 4% draw that starts at 62 has to last longer than one that starts at 65 or 67, so $1.3 million is a tight fit if the 401(k) carries the whole load for life. It won’t have to, though. Once Social Security checks start, the 401(k) only has to cover what they don’t, and the withdrawal it needs shrinks. At 65, Medicare replaces Marketplace coverage, and the extra deductions for older filers start.

Frankly, $1.3 million is a high bar that most early retirees won’t need to clear for good, since Social Security will pick up part of that $48,000. Until 65, I’d worry more about the 400% line than about the tax bill. Of course, Congress could still bring back the expanded credit, and that would change the math for anyone near the line.
