401(k) Distributions: Rules, Penalties, and Tax Treatment

The 401(k) distribution rules set out when you can pull money from your account, how it will be taxed, and when a penalty gets tacked on. In short: federal law limits withdrawals to specific triggering events, distributions from a traditional 401(k) are taxed as ordinary income in the year you take them, and if you’re under 59½ you generally owe an extra 10% on top unless you qualify for an exception.1Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans

When You Can Take a Distribution

You can’t withdraw from a 401(k) on demand. Federal tax law limits distributions to a defined set of events:

  • Separation from service — you quit, get laid off, or are fired, which makes your vested balance distributable.
  • Reaching age 59½, which lets you withdraw from profit-sharing and stock bonus plans even while still working.
  • Total and permanent disability.
  • Death, which lets your designated beneficiaries claim the balance.
  • Plan termination, if your employer shuts the plan down without setting up a successor. Every affected participant must be fully vested and paid out, typically within 12 months.2Internal Revenue Service. Terminating a Retirement Plan
  • Hardship, if the plan document allows it.

One trap to know: if your employer terminates the plan but establishes another one that counts as a successor, your deferrals stay locked. They roll into the new plan and wait for another qualifying event.

How 401(k) Distributions Are Taxed

A distribution from a traditional 401(k) is ordinary income for the year you receive it.3Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust The amount stacks on top of your other earnings and is taxed at your marginal rate. Federal rates for 2026 run from 10% to 37%.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026

When the plan pays you directly instead of rolling the funds over, the administrator must withhold 20% for federal income tax.5Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules That withholding is a prepayment. If your final tax rate is lower, you get the difference back; if it’s higher, you owe more at filing time. You can elect a higher withholding percentage at the time of the distribution.

Most states also tax 401(k) distributions as ordinary income. Rates range from 0% in states with no income tax up to roughly 13% at the top. Thirteen states currently don’t tax traditional 401(k) and IRA distributions, including Alaska, Florida, Nevada, Texas, and Wyoming, and several others exempt part of retirement income. Your state of residence in the year of the distribution controls, which is worth thinking about if you’re planning a move around retirement.

The 10% Early Withdrawal Penalty

Withdraw before age 59½ and you generally owe a 10% additional tax on the taxable portion of the distribution, reported on Form 5329.6Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions

The combined bite is significant. A 35-year-old in the 22% bracket who withdraws $20,000 early loses $4,400 to income tax and $2,000 to the penalty, keeping $13,600. That’s a 32% cut before state taxes.

Exceptions That Waive the Penalty

Several situations let you skip the 10% even if you’re under 59½. Income tax on traditional 401(k) funds still applies; only the penalty goes away.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions

  • Rule of 55: if you leave your job in or after the calendar year you turn 55, distributions from that employer’s plan are penalty-free. Public safety employees in governmental plans qualify at 50. Only the most recent employer’s plan is covered; old 401(k)s from earlier jobs are not.
  • Total and permanent disability, as defined under federal tax law.
  • Death: beneficiaries never owe the early withdrawal penalty regardless of age.
  • Qualified Domestic Relations Order payments to a former spouse or dependent.
  • Unreimbursed medical expenses that exceed 7.5% of your adjusted gross income.
  • IRS levy on the retirement account to collect a tax debt.
  • Terminal illness, with physician certification.

The SECURE Act 2.0 added two more, both optional for plans to adopt. An emergency personal expense distribution lets you take up to $1,000 per calendar year for an unforeseeable personal or family emergency without penalty, repayable within three years; you can’t take another from the same plan during those three years unless you’ve repaid the earlier one or replaced it through new contributions.8Internal Revenue Service. Notice 2024-55 A domestic abuse victim distribution lets a self-certifying survivor withdraw the lesser of $10,000 or 50% of the vested balance within 12 months of the incident.

Substantially Equal Periodic Payments

If nothing else fits, you can commit to a series of substantially equal periodic payments based on your life expectancy — often called 72(t) payments — and avoid the penalty that way.9Internal Revenue Service. Substantially Equal Periodic Payments Once you start, you can’t change the amount until the later of five years or the date you reach 59½. Modify early for any reason other than death or disability, and the IRS retroactively applies the 10% penalty to every distribution you took, plus interest. For 401(k) plans, you must have separated from the employer maintaining the plan before payments can begin, which is one reason people sometimes roll a 401(k) to an IRA before starting a SEPP.

Hardship Withdrawals

Hardship withdrawals are an optional plan feature, so your plan document controls whether they’re available. When allowed, the distribution can’t exceed the amount of your immediate and heavy financial need, though you can include enough to cover the resulting taxes and penalties.10Internal Revenue Service. Retirement Plans FAQs Regarding Hardship Distributions

The IRS automatically treats these expenses as qualifying: certain unreimbursed medical costs for you, your spouse, or dependents; costs of buying a primary residence (not mortgage payments); tuition and related fees for the next 12 months; payments needed to prevent eviction or foreclosure on your primary residence; funeral expenses; casualty-loss repairs to your primary residence; and expenses and lost income from a federally declared disaster affecting your home or workplace.

Employers can generally rely on your written statement that you qualify, unless they have actual knowledge you could cover the need through insurance, plan loans, or liquid assets. A hardship distribution is taxed as ordinary income and, if you’re under 59½, typically hit with the 10% penalty. Unlike a plan loan, you cannot repay a hardship withdrawal back into the account.

Rollovers: The Way to Avoid the Tax Hit

When a distribution event happens, cashing out isn’t the only option. Rolling the money into another retirement account keeps the tax deferral going.

In a direct rollover, your plan administrator sends the money straight to a new plan or IRA. Nothing is withheld, and no tax is owed on the transfer.11Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions

In an indirect (60-day) rollover, the plan pays you and you have 60 days to deposit the money into another eligible account. The plan withholds 20% for federal taxes before writing the check. Withdraw $50,000 and you receive $40,000. To complete a fully tax-free rollover, you must deposit the full $50,000 within 60 days, covering the $10,000 gap out of pocket. Roll over only the $40,000 you received, and the $10,000 withheld becomes taxable income, potentially with the 10% penalty on top if you’re under 59½. Miss the 60-day window entirely and the whole distribution is taxable.

Required Minimum Distributions

You can’t keep money in a traditional 401(k) indefinitely. You must begin required minimum distributions (RMDs) by April 1 of the year after you turn 73.12Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Under SECURE Act 2.0, that age is scheduled to rise to 75 starting in 2033. The annual RMD is your prior-year December 31 balance divided by a life expectancy factor from IRS tables, so the amount shifts each year.

Still working past 73 and don’t own more than 5% of the company? You can delay RMDs from your current employer’s 401(k) until you actually retire. That still-working exception only covers the current employer’s plan; balances at former employers must begin RMDs on the normal schedule.

Miss an RMD and you owe a 25% excise tax on the shortfall, dropping to 10% if you take the missed amount within two years.13Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) SECURE Act 2.0 cut what used to be a 50% penalty. Report the excise tax on Form 5329.

Designated Roth 401(k) accounts are no longer subject to RMDs during the owner’s lifetime for tax years beginning after December 31, 2023.12Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Beneficiaries who inherit a Roth 401(k) are still subject to post-death distribution rules.

Roth 401(k) Distributions

Roth 401(k) contributions go in after tax, so the rules on the way out are different. A “qualified distribution” from a Roth 401(k) is entirely tax-free — contributions and earnings both.14Internal Revenue Service. Retirement Plans FAQs on Designated Roth Accounts

Two conditions must be met:

  • At least five tax years have passed since your first Roth contribution to the plan. The clock starts on January 1 of the year of that first contribution.
  • You are at least 59½, disabled, or the distribution is paid after your death.

Take money out before hitting both, and your original contributions still come back tax-free (you already paid tax on them), but the earnings portion is taxable and can be hit with the 10% penalty.

When a Plan Loan Turns Into a Distribution

Many plans let you borrow the lesser of $50,000 or 50% of your vested balance.15Internal Revenue Service. Borrowing Limits for Participants With Multiple Plan Loans A loan repaid on schedule is not a distribution and is not taxable. Miss payments or leave your employer with an unpaid balance, and the unpaid amount becomes a “deemed distribution”: the IRS treats it as if you received a taxable distribution equal to the remaining loan balance plus accrued interest.16Internal Revenue Service. Fixing Common Plan Mistakes – Plan Loan Failures and Deemed Distributions The 10% penalty typically applies if you’re under 59½. And even after the tax treatment kicks in, you may still owe the outstanding balance to the plan.

How to Request a Distribution

The process starts with a distribution request form from your employer’s HR portal or the plan’s record-keeper. You’ll typically need:

  • Your plan account number.
  • Social Security number and current mailing address.
  • Whether you want a full or partial distribution.
  • Your delivery method: direct rollover, paper check, or electronic transfer.
  • Bank routing and account numbers for electronic transfers.
  • Your federal tax withholding election. The default is 20% for non-rollover distributions; you can elect more.

If your plan is subject to qualified joint and survivor annuity rules, a married participant taking a distribution in any form other than a joint annuity needs written spousal consent, witnessed by a plan representative or a notary.17Internal Revenue Service. Retirement Topics – Qualified Joint and Survivor Annuity Not every 401(k) has these rules; some plans adopt them voluntarily.

Electronic transfers usually settle within one to two business days after the administrator releases the funds. Paper checks take longer. Most straightforward requests process within a few business days to two weeks; plan-termination payouts or requests needing spousal consent can run longer.
