Early 401(k) and IRA Withdrawals: Tax, Penalties, and Exceptions

Separate income tax, the penalty, and withholding

A fully taxable traditional 401(k) or IRA withdrawal increases ordinary taxable income. The added amount can occupy more than one tax bracket, so multiplying the whole distribution by your current marginal rate is not always enough. Compare income tax before and after the withdrawal, then calculate any additional early-distribution tax separately. State tax and account fees can add further costs.

Withholding is cash sent to the IRS on your behalf. It reduces the payment received now and is credited against your eventual return balance. Do not add withholding to the projected income tax as though it were another expense. A plan can withhold too little or too much compared with the final tax and penalty, especially when other income or deductions change during the year.

Worked example: a $10,000 withdrawal

The $6,800 is an after-final-tax planning amount, not a guarantee about the check a custodian will issue. If an eligible exception removes the entire $1,000 additional tax, the same hypothetical income-tax cost leaves $7,800. If only part of the distribution qualifies for an exception, calculate the additional tax on the remainder rather than waiving it for the whole withdrawal.

For a bracket-crossing example, use 2026 single-filer taxable income of $100,000 before a $10,000 withdrawal. The first $5,700 of the withdrawal occupies the 22% range and the remaining $4,300 occupies the 24% range, adding $2,286 of income tax. With the usual $1,000 additional tax, the projected federal cost is $3,286 and the remaining amount is $6,714 before state tax and fees.

The age-55 rule is not an IRA exception

A qualifying employer-plan distribution may escape the additional tax when separation from that employer occurs during or after the calendar year you reach age 55. This does not make every account penalty-free at 55, and it does not apply to an IRA merely because money previously came from a 401(k). Certain public-safety and other designated workers have different conditions. Check the exact plan and separation facts before moving funds or taking a distribution.

Other exceptions can depend on medical expenses, disability, death, a qualifying series of payments, or specific statutory circumstances. IRA-specific provisions include certain education and first-home situations that are not interchangeable with employer-plan exceptions. A hardship approval from a plan is not, by itself, proof that the distribution qualifies for a tax exception. Use the IRS exception chart and retain supporting records.

Roth IRA contributions, earnings, and conversions differ

Roth IRA regular contributions generally come out ahead of conversions and earnings under the ordering rules. A distribution attributable to those regular contributions is different from withdrawing earnings. Qualified Roth IRA earnings distributions require the applicable holding period and a qualifying condition such as age 59 1/2. A conversion can involve another five-year rule for additional-tax purposes, so one simple holding-period answer does not resolve every Roth distribution.

The linked calculator models identified regular-contribution or earnings scenarios, not the full ordering of a mixed Roth IRA distribution. It also does not apply Roth IRA ordering to a Roth 401(k), calculate nondeductible traditional IRA basis, or model the special SIMPLE IRA first-two-year rule. Review the custodian's records and the account-specific instructions when any of those facts apply.

Records and filing checks before taking money out

Choose the distribution year in the calculator, not the year you plan to file the return. For 2027 planning, read the published-versus-provisional notice: the ordinary bracket thresholds may still use the latest published schedule. A preliminary estimate cannot establish final indexed amounts, eligibility for an exception, or the effect on every income-based credit and benefit.

• Confirm the account type, taxable portion, age, and distribution reason before selecting an exception.
• Keep Form 1099-R, basis and conversion records, and evidence supporting any claimed exception.
• Review whether Form 5329 is required, including when a distribution code does not identify the exception you claim.
• Compare withholding with the full-year income-tax and additional-tax projection; consider payment timing separately.
