Federal income tax
A traditional pretax distribution generally adds to your taxable income for the year. The tax impact depends on your overall income and applicable tax rules.
401k Calculator & Guide
Withdrawing money from a 401(k) can have different tax consequences depending on whether your account is traditional or Roth, your age, the reason for the distribution, and whether an exception applies. Understand federal income tax, possible state taxes, withholding, and the additional tax that can apply to early withdrawals.
The tax treatment depends on the type of account and distribution. Traditional pretax 401(k) withdrawals are generally taxable as ordinary income. Qualified Roth 401(k) distributions can be tax-free when the applicable requirements are met. An additional 10% federal tax may apply to certain early taxable distributions unless an exception is available.
A traditional pretax distribution generally adds to your taxable income for the year. The tax impact depends on your overall income and applicable tax rules.
Many taxable distributions before age 59½ may face an additional 10% tax unless a statutory exception applies.
State treatment varies. Your state may tax some retirement distributions, offer an exclusion, or follow special rules.
| Feature | Traditional 401(k) | Roth 401(k) |
|---|---|---|
| Contributions | Traditional pretax contributions generally receive tax-deferred treatment. | Roth contributions are generally made with after-tax dollars. |
| Qualified retirement distribution | Generally taxable as ordinary income to the extent it represents pretax amounts. | Generally tax-free if the distribution meets the qualified-distribution rules. |
| Early distribution | Taxable amounts may be subject to ordinary income tax and an additional 10% tax unless an exception applies. | Nonqualified distributions have special allocation and earnings rules; tax and additional-tax treatment can differ. |
| Tax treatment of employer match | Employer contributions are generally tax-deferred until distributed, subject to applicable rules. | Employer matching contributions have traditionally been placed in a pretax source, although current law permits certain plans to offer vested Roth matching contributions. Check your plan's treatment. |

Use this simplified tool to estimate a possible income-tax amount and additional early-distribution tax on a hypothetical withdrawal. It is not a tax-return calculator and does not determine whether you qualify for an exception.
Simplified illustration based on the values entered.
Method: taxable amount = gross withdrawal × taxable percentage. The estimator applies the entered federal and state rates to that amount, plus an additional 10% tax if the age is under 59½ and the exception setting is “No / not sure.” It does not calculate progressive tax brackets, credits, deductions, withholding, or state-specific rules. Your actual liability may differ materially.
Many taxable distributions from a qualified retirement plan before age 59½ are subject to an additional 10% federal tax unless a statutory exception applies. The additional tax is separate from regular income tax.
A $10,000 fully taxable early distribution could produce a $1,000 additional tax if no exception applies, plus any regular income tax due.
Rules may cover certain age-55 separations from service, disability, qualifying medical expenses, QDRO distributions, and other specific situations.
Examples are not exhaustive, and exceptions have precise conditions. An exception to the additional tax does not automatically make a traditional 401(k) distribution income-tax-free.
Read the IRS guidance: Exceptions to tax on early distributions.
Withholding is money set aside from a payment toward potential tax liability. It is not necessarily the final amount of tax you owe. Your final liability depends on your total taxable income, deductions, credits, other income, and applicable rules.
| Term | What it means | What to remember |
|---|---|---|
| Income tax | Tax owed on the taxable portion of a distribution under the applicable rules. | Your overall tax situation affects the final amount. |
| Additional early-distribution tax | A separate federal tax that can apply to certain early taxable distributions. | Exceptions may apply, but eligibility must be established. |
| Withholding | Money withheld and sent toward your tax obligation. | It may not equal the final tax due. |
| Net payment | The amount you receive after withholding and any plan-level deductions. | It is not necessarily the amount you can keep after filing your tax return. |
| Situation | General rule | Important detail |
|---|---|---|
| Age 59½ or older | The additional 10% tax generally no longer applies. | Taxable traditional distributions may still be included in income. |
| Separation from service at age 55 or later | Certain distributions from an employer plan may qualify if separation occurs during or after the calendar year you turn 55. | Generally not available for IRA withdrawals; timing and plan type matter. |
| Qualifying disability or death | Specified distributions may qualify for an exception. | Definitions and beneficiary rules apply. |
| Qualifying medical expenses | Some eligible distributions may qualify up to the statutory amount. | Documentation and calculation rules matter. |
| Other statutory circumstances | Special rules may apply for qualifying domestic relations orders, periodic payments, disasters, military service, terminal illness, or an IRS levy. | Check the exact conditions in current IRS guidance. |

It depends on the account type, taxable portion, total income, filing situation, state tax rules, and whether an additional early-distribution tax applies. There is no single tax rate for every withdrawal.
Traditional pretax distributions are generally included in ordinary taxable income, subject to applicable rules. The final tax impact depends on your overall tax situation.
Qualified Roth 401(k) distributions are generally tax-free if the applicable five-tax-year and qualifying-event requirements are met. Nonqualified distributions can have different tax treatment.
Yes. It is an additional federal tax that may apply to certain early taxable distributions. Regular income tax may also apply.
Certain distributions from a qualified employer plan may qualify for the separation-from-service exception if you leave the employer during or after the calendar year you turn 55. The exception generally does not apply to IRA withdrawals.
No. Withholding is a prepayment. Your actual tax due or refund is determined when your tax liability is calculated, taking into account your total income, applicable taxes, payments, and other factors.
A properly completed eligible direct rollover generally receives different tax treatment from a cash distribution. Indirect rollovers can involve withholding and strict deadlines. Confirm the transaction type and current rules before moving funds.
