To cash out a 401(k), you stop your contributions, wait for a qualifying event (usually leaving the job), submit a distribution election form to your plan, and take the vested balance as a lump sum. Expect the plan to withhold 20% for federal income tax before you see a dollar, and expect to owe another 10% penalty on top of ordinary income tax if you’re under 59½. Between federal withholding, the penalty, and state tax, roughly a third of the account can disappear before it reaches you.
When You’re Allowed to Cash Out
Federal tax law only lets you take a full distribution after a specific triggering event: leaving your job (quit, laid off, or retired), becoming permanently disabled, reaching age 59½ while still employed if the plan allows in-service withdrawals, or death (in which case your beneficiary receives the funds).1Office of the Law Revision Counsel. 26 U.S. Code 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans
If you’re still working for the employer sponsoring the plan and you’re under 59½, a full cash-out generally isn’t on the table. The most you can usually get is a hardship withdrawal, and only if your plan permits them. The IRS recognizes safe-harbor hardships that automatically qualify:
- Medical expenses for you, your spouse, dependents, or a plan beneficiary
- Costs directly tied to buying your principal residence (not mortgage payments)
- Tuition, fees, and room and board for the next 12 months of postsecondary education for you or your family
- Payments needed to prevent eviction from or foreclosure on your primary home
- Funeral expenses for you, your spouse, children, dependents, or a beneficiary
- Certain repairs to damage on your principal residence
A hardship distribution is still taxed as ordinary income and still triggers the 10% penalty if you’re under 59½.2Internal Revenue Service. Retirement Topics – Hardship Distributions
What You Actually Get: Vesting and the Withholding
The money you contributed from your own paychecks is 100% yours from day one. Employer contributions — matching or profit-sharing — follow a vesting schedule. Only the vested portion pays out; the rest goes back to the employer when you leave.3Internal Revenue Service. Retirement Topics – Vesting
Federal law allows two main structures for employer money:
- Three-year cliff vesting: 0% vested until three years of service, then 100% at once.
- Six-year graded vesting: 20% after two years, then 20% more each year, reaching 100% at six years.
Check your latest benefits statement or ask the plan administrator for your vested balance before you request anything. That is the number you’re actually cashing out.
Once you request the distribution, the plan is required to withhold 20% for federal income tax on any eligible rollover distribution paid in cash.4Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income That withholding is a prepayment sent to the IRS, not the final tax bill. Your actual liability depends on your total income for the year, so you may owe more when you file, or get some back. State income tax withholding may apply on top, depending on where you live.
After the distribution the plan sends you Form 1099-R showing the gross amount, the taxable portion, and taxes withheld. You use it to file that year’s federal return.5Internal Revenue Service. About Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc.
The 10% Early Withdrawal Penalty
If you’re younger than 59½ when the distribution goes out, you owe an extra 10% on the taxable portion, on top of ordinary income tax.6Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts The plan doesn’t withhold the penalty. You owe it when you file.
Here’s the math on a $50,000 cash-out before 59½. The plan withholds $10,000 and sends you $40,000. At tax time you owe ordinary income tax on the full $50,000 at your marginal rate, plus a $5,000 penalty. The $10,000 already withheld is credited against the total, but you’ll likely still owe more when you file. A large distribution can also push part of your income into a higher bracket, so the last dollars of the cash-out may be taxed at a rate your regular wages wouldn’t hit.
Exceptions to the 10% Penalty
Several situations remove the 10% penalty even if you’re under 59½:7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
- Rule of 55: you leave the job during or after the calendar year you turn 55 (age 50 for public safety employees of a state or local government).
- Total and permanent disability as defined by the IRS.
- Death (distributions to your beneficiary are penalty-free).
- Substantially equal periodic payments based on life expectancy, continued for at least five years or until you reach 59½, whichever is later.
- Payments to an alternate payee under a qualified domestic relations order (for example, a former spouse).
- Unreimbursed medical expenses above 7.5% of your adjusted gross income.
- An IRS levy on the plan.
- Qualified military reservist called to active duty for at least 180 days.
- Federally declared disaster distributions up to $22,000.
- Qualified birth or adoption expenses up to $5,000 per child.
- Domestic abuse victim distributions up to the lesser of $10,000 or 50% of the account, for distributions after December 31, 2023.
- One emergency personal expense distribution per year up to the lesser of $1,000 or your vested balance above $1,000, for distributions after December 31, 2023.
The substantially equal periodic payments route requires an IRS-approved calculation method, and you can’t modify the schedule before the later of five years or reaching 59½ without triggering a retroactive recapture tax on all prior payments.8Internal Revenue Service. Substantially Equal Periodic Payments You also have to be separated from service before starting SEPP from a 401(k).
An exception only removes the 10% penalty. You still owe ordinary income tax on the distribution.
How to Submit the Cash-Out Request
Stop New Contributions First
Stopping contributions is separate from cashing out. Log into your employer’s payroll portal or contact HR and set your deferral percentage to zero. The change usually takes one to two pay cycles. Your existing balance stays invested until you actually request the distribution.
Complete the Distribution Election Form
Contact your plan administrator (or use the participant portal) for a distribution election form. You’ll provide your Social Security number, plan account number, how you want the money delivered, and whether you want more than the mandatory 20% withheld for federal tax.
If your plan is subject to the joint and survivor annuity rules and you’re married, your spouse must sign a written consent waiving survivor benefits, witnessed by a plan representative or notary.9Office of the Law Revision Counsel. 26 USC 417 – Definitions and Special Rules for Purposes of Minimum Survivor Annuity Requirements Without properly witnessed spousal consent, the plan will deny the request.
Submit the form through the participant portal, or by mail or fax if the plan doesn’t handle it electronically. Save confirmation screens or email receipts.
The Notice Period and Payout
Before processing, the plan must give you a written explanation of your rollover options and the tax consequences of taking cash. You generally have at least 30 days to review it. You can sign a waiver to shorten that window if you want the money sooner.
Once the notice period passes (or you waive it), the custodian liquidates the investments and pays out either by electronic transfer to the bank account on your form (usually a few business days) or by paper check mailed to the address on file. When the balance hits zero, the account closes.
The 60-Day Rollover Window if You Change Your Mind
Even after the check arrives, you have 60 days to deposit all or part of the distribution into an IRA or another eligible retirement plan and avoid tax on the amount rolled over.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions This is an indirect rollover.
The trap is the 20% already withheld. To roll over the full original amount and owe no tax, you have to make up that 20% out of your own pocket and deposit the whole gross figure within 60 days. Roll over only the 80% you received, and the withheld 20% is treated as a taxable distribution (and may face the 10% penalty). You’ll get the withholding back as a refund when you file, but only after fronting the money.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions The IRS may waive the 60-day deadline for circumstances beyond your control, but relief isn’t guaranteed.
Alternatives Before You Cash Out
A direct rollover moves the money straight from your plan to an IRA or a new employer’s 401(k) without paying you, so no 20% withholding and no 10% penalty apply. You owe no tax on the transfer and the balance keeps growing.11Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans
If you need cash but are still employed, a 401(k) loan lets you borrow the lesser of $50,000 or 50% of your vested balance and pay yourself back with interest, generally over five years (longer if used to buy your primary residence). Because you’re borrowing, not distributing, no tax hits as long as you keep up the payments.12Internal Revenue Service. Retirement Topics – Loans The risk: if you leave the job, the plan may demand full repayment, and any unpaid balance becomes a taxable distribution with the 10% penalty attached if you’re under 59½.13Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts You can avoid that by rolling the unpaid loan balance into an IRA or another eligible plan by the due date of your tax return (including extensions) for the year the loan is deemed distributed.
