How a 401(k) withdrawal is taxed

A traditional 401(k) withdrawal is added to your taxable income for the year and taxed at ordinary rates — not the lower capital-gains rates. Because it stacks on top of your other income, the withdrawal fills your remaining lower brackets first, then spills into higher ones, so a big withdrawal in one year is taxed harder than a small one.

This calculator applies the 2026 federal brackets for your filing status, subtracts the standard deduction from your total income, and measures the extra tax the withdrawal alone creates — the honest “stacked” number, not a flat guess. State income tax is added as a flat estimate you set, and the 10% early-withdrawal penalty is included if you’re under 59½ without an exception.

A worked example

Take $25,000 from a traditional 401(k) at age 45, on top of $60,000 of other income, filing single, in a 5% state:

  • Federal tax on the withdrawal: about $4,850 — part fills your 12% bracket, the rest is taxed at 22%.
  • State tax: $1,250
  • 10% penalty: $2,500
  • You keep: about $16,400 — an effective rate near 34%.

Withholding is separate: plans usually withhold a mandatory 20% federal up front, but that’s a prepayment, not your final bill — you settle up when you file.

Ways the tax can be lower — or higher

The single biggest lever is timing. Spreading withdrawals across several years keeps more of each one in the lower brackets, while one large withdrawal can push a chunk into 24%, 32%, or beyond. Your age, filing status, and state all move the number too.

  • Spread it out. Two $25,000 withdrawals in different years usually beat one $50,000 withdrawal, because each fills the lower brackets again.
  • Wait until 59½ if you can, to drop the 10% penalty entirely — see the early withdrawal calculator for the penalty math.
  • Consider a loan instead. A 401(k) loan avoids tax and penalty if you repay it on schedule.
  • Roth withdrawals are tax-free. If you have a Roth 401(k), qualified withdrawals don’t add to this bill — compare the two with the Roth 401(k) calculator.

401(k) withdrawal tax — FAQ

How much tax do you pay on a 401(k) withdrawal?
It’s taxed as ordinary income at your federal and state rates, stacked on your other income, plus a 10% penalty if you’re under 59½. Part of a large withdrawal can land in a higher bracket than your other income.
Is it taxed as income or capital gains?
Ordinary income, not capital gains — even though the growth came from investments. That’s the trade-off for the up-front deduction. Qualified Roth 401(k) withdrawals are tax-free.
How much is withheld for taxes?
Plans generally withhold a mandatory 20% federal, but that’s a prepayment, not your final tax. Your actual bill depends on total income, filing status, and state, and is settled when you file.
Will a withdrawal push me into a higher bracket?
It can push part of the withdrawal into a higher bracket, but only the amount above each threshold is taxed at the higher rate — your whole income isn’t retaxed. Spreading withdrawals across years keeps more in the lower brackets.
