Are RMDs taxable?

Usually, required minimum distributions from a traditional 401(k), traditional IRA, or similar tax-deferred retirement account are included in ordinary income for federal income tax purposes. The amount you receive may increase your taxable income for the year, depending on your account type and the source of the money.

Your actual tax bill depends on your other income, filing status, deductions, applicable tax brackets, state tax rules, and whether any portion of the distribution represents after-tax basis or qualifies for special treatment. An RMD is not automatically taxed at one fixed rate.

Key distinction: The RMD is the amount you are generally required to withdraw. The tax you owe depends on your broader tax situation. Federal tax withholding from the payment is a prepayment toward tax, not necessarily your final tax liability.
💵

Ordinary income

Most pre-tax retirement distributions are generally taxed as ordinary income, not at the capital-gains rate.

🧾

Tax withholding

You may be able to request withholding from a distribution. The amount withheld may differ from the final tax owed.

📊

Income effects

A larger distribution can affect tax brackets and income-based calculations, including Medicare premiums in some circumstances.

How RMD taxes vary by account type

Account or distributionGeneral federal tax treatmentWhat to check
Traditional 401(k)Pre-tax distributions are generally included in ordinary income.Plan rules, after-tax basis, and withholding election.
Traditional IRAGenerally taxable to the extent the distribution consists of pre-tax money.Any nondeductible contributions and applicable basis records.
Designated Roth 401(k)RMDs generally do not apply to the original account owner during life under current rules. A distribution, when taken, is tax-free only if it meets qualified-distribution rules.Qualified-distribution requirements and beneficiary rules.
Roth IRA owned by the original ownerNo lifetime RMDs generally apply to the original owner.Different distribution rules can apply after the owner's death.
Inherited retirement accountTax treatment depends on the account type and beneficiary/distribution rules.Beneficiary status, account type, and applicable deadlines.

These are general federal rules, not a determination for every account. Roth status alone does not make every distribution tax-free; qualified-distribution requirements and plan rules matter.

RMD tax estimator

Use this simple estimator to model an assumed effective tax rate and withholding percentage. It does not calculate your actual federal tax bracket, state taxes, credits, or other income-related effects.

Illustrative estimated tax on this RMD
$4,000
Estimated after-tax amount$16,000
Withheld from RMD$2,000
Estimated tax not covered by withholding$2,000

The final figure subtracts withholding and other planned tax payments from the illustrative tax estimate. A negative figure indicates an estimated excess of payments relative to this simplified estimate, not a guaranteed refund.

Important: The effective tax rate you enter is only an assumption. Your marginal tax rate, effective tax rate, and withholding rate are different concepts. Use current IRS guidance or a qualified tax professional for an estimate based on your complete tax return.

RMD withholding and estimated tax payments

Taking an RMD does not necessarily mean enough tax has been paid. Your plan or financial institution may offer federal income tax withholding options, and you may also be able to make estimated tax payments. Availability and procedures vary by distribution type and provider.

Withholding from the distribution

Some of the distribution is sent toward taxes and the remainder is paid to you. Check the provider's election form, payment timing, and any applicable default withholding rules.

Estimated tax payments

If withholding and other payments may not cover your tax obligations, estimated payments could be relevant. IRS rules determine whether underpayment penalties may apply.

Don't choose a withholding percentage based only on the RMD amount. Consider your total annual income, filing status, deductions, other withholding, and any state tax obligations.

See the IRS information on required minimum distributions and tax payments.

What happens if you miss an RMD?

If you fail to withdraw the required amount by the applicable deadline, an excise tax may apply to the shortfall. Under current federal rules, the excise tax is generally 25% of the amount not distributed when required. It may be reduced to 10% if the shortfall is corrected within the applicable correction window.

The IRS may waive the excise tax when the shortfall resulted from reasonable error and reasonable steps are being taken to remedy it. A waiver is not automatic; follow current IRS filing instructions and document what happened and how it was corrected.

Don't confuse the two tax issues: Income tax on a taxable distribution is separate from the excise tax that may apply when an RMD is missed or underpaid. Taking a late distribution may not eliminate every reporting obligation.

Confirm your required amount and deadline before taking action. Start with when 401(k) RMDs start and how RMDs are calculated.

Can you roll an RMD into another retirement account?

An RMD generally is not eligible for rollover treatment. If you are moving retirement assets to another account, the required distribution generally must be satisfied separately rather than treated as an eligible rollover distribution. Rules can differ depending on account type and transaction details, so confirm the sequence with your plan administrator or tax professional before initiating a rollover.

If you are already retired, also review the practical account and distribution considerations in our 401(k) after retirement guide.

RMD tax preparation checklist

  • Confirm the RMD amount and deadline for every applicable account.
  • Identify whether the distribution is from a traditional, Roth, inherited, or other account.
  • Review the account's pre-tax and after-tax basis records where relevant.
  • Estimate your total annual taxable income instead of taxing the RMD in isolation.
  • Check federal and state withholding options and any estimated payment needs.
  • Keep distribution confirmations and tax forms with your records.
  • If a distribution was missed, contact the plan or custodian and review current IRS correction and filing instructions promptly.

Frequently asked questions

Are RMDs taxed as ordinary income?

Most distributions from pre-tax traditional 401(k)s and traditional IRAs are generally included in ordinary income. The taxable amount can differ if the account includes after-tax basis or another exception applies.

Does taking an RMD automatically mean taxes are paid?

No. A distribution may have tax withheld, but the withholding amount is a payment toward your tax. Your final liability depends on your complete tax situation.

Are Roth 401(k) RMDs taxable?

Under current rules, the original owner generally does not have lifetime RMDs from a designated Roth 401(k). When a distribution is taken, whether it is tax-free depends on the qualified-distribution rules. Beneficiary situations can be different.

Can an RMD push me into a higher tax bracket?

It can increase your taxable income and may cause some income to fall into a higher marginal tax bracket. The entire RMD is not automatically taxed at that higher marginal rate.

What is the penalty for missing an RMD?

The excise tax is generally 25% of the shortfall and may be reduced to 10% if corrected within the applicable correction window. The IRS may waive it in qualifying reasonable-error situations when corrective steps are taken.

Can I donate an RMD to charity and avoid tax?

Potentially, a qualifying direct transfer from an eligible IRA to a qualified charity may receive treatment as a qualified charitable distribution (QCD), subject to eligibility and limits. QCD rules do not generally apply to distributions directly from a 401(k). Verify the current IRS requirements before arranging a transfer.
