401(k) Early Withdrawal Tax Calculator
Withdrawal Amount
Pre-tax 401(k) money only. Roth 401(k) and after-tax basis aren't modeled.
Your Age
The IRS uses your exact age at the date of distribution, not your age at year end.
Other Annual Income
Wages, self-employment, and your spouse's income if you file jointly. Exclude this withdrawal.
Filing Status
State
Penalty Exception
First-time home purchase, higher education, and health insurance while unemployed are IRA-only, so they are not listed here. A hardship withdrawal is not an exception either.
Assumed Annual Return
Only used for the balance you give up by cashing out instead of leaving the money invested until 65.
The 20% is a prepayment, not your final tax bill.
Your federal withholding covers the federal bill exactly.
Estimates only. Not tax, legal, or investment advice. Consult a tax professional before you take a distribution.
No FICA On The Way Out
A 401(k) distribution isn't subject to Social Security or Medicare tax. Your deferrals were already taxed for FICA when they came out of your paycheck (IRC 3121(v)(1)(A)), so there's no 6.2% or 1.45% line here, on purpose.
What It Costs You
Notes
- An exception waives the 10% penalty only. The withdrawal is still ordinary income and still taxed.

Pay44 handles federal, state, and FICA withholding for all 50 states, so you can see whether a payroll change beats cashing out your 401(k).
What a 401(k) early withdrawal actually costs
Cashing out a 401(k) before 59.5 means a three-part bill. First, the distribution is ordinary income, taxed at your marginal federal rate once it stacks on top of everything else you earned that year. Second, IRC 72(t) adds a 10% additional tax unless an exception applies. Third, most states tax the distribution as income too.
The stacking matters more than people expect. A $30,000 withdrawal on top of $50,000 of wages doesn't get taxed at one neat rate: part of it fills the rest of the 12% bracket and the rest lands in 22%. That's why this tool asks for your other income and filing status instead of making you pick a bracket.
What's not in the bill: Social Security and Medicare tax. Your deferrals were already hit for FICA when they left your paycheck, so distributions are income-taxable only. If you're used to seeing a FICA row on a paycheck estimate, its absence here is correct, not a bug.
Worked example: $20,000 withdrawn by a single filer with $60,000 of other income in a state with roughly a 5% rate costs about $3,750 in federal income tax, $2,000 in penalty, and about $1,000 in state tax, leaving roughly $13,250. Change the inputs above and the whole chain updates.
The 20% withheld is not your tax bill
When a plan pays an eligible rollover distribution directly to you instead of moving it by direct rollover, IRC 3405(c) requires the administrator to withhold 20% for federal income tax. You can't elect out of it. That 20% is a deposit against your return, exactly like paycheck withholding.
The plan doesn't withhold the 10% penalty, which you compute on Form 5329 at filing. It doesn't withhold state tax either. So the settle-up question is simple: if your federal income tax on the withdrawal plus the penalty is more than the 20% withheld, you write a check. If it's less, you get a refund. For most people under 59.5 in the 22% bracket or above, 20% isn't enough and there's a balance due.
Two cases withhold differently. A hardship distribution isn't an eligible rollover distribution, so it defaults to 10% withholding under Form W-4R. A 72(t) series is a periodic payment withheld under Form W-4P rules. In both cases the cash you receive differs, but the final liability (income tax plus the additional tax) is the same.
The exceptions that actually waive the 10% penalty
For a 401(k), the penalty exceptions that matter are: separation from service in or after the year you turn 55, total and permanent disability, substantially equal periodic payments under 72(t), unreimbursed medical expenses above 7.5% of AGI, a QDRO, an IRS levy, qualified birth or adoption, terminal illness, domestic abuse, a federally declared disaster, an emergency personal expense, and qualified reservist distributions.
Three well-known exceptions are IRA-only and never apply to a 401(k): first-time home purchase, qualified higher education expenses, and health insurance premiums while unemployed. Rolling a 401(k) to an IRA to reach them is a real strategy, but it also forfeits the rule of 55, which applies only to the plan of the employer you left.
And the big one: a hardship withdrawal isn't an exception. Hardship rules govern whether the plan may release the money. Form 5329 has no hardship code. You still owe the 10% unless the underlying facts independently qualify.
Every exception on that list waives the penalty and nothing else. The withdrawal remains fully taxable ordinary income.
Alternatives before you cash out
A 401(k) loan avoids both the income tax and the penalty as long as you repay on schedule, though leaving the job can accelerate repayment. Leaving the balance where it is, or rolling it into your next employer's plan or an IRA, keeps the money compounding and costs nothing in tax.
The compounding is the quiet cost. $20,000 taken at 35 and left alone until 65 at 7% a year would have grown to roughly $152,000. Weigh that against whatever the cash is for.
If the goal is more cash flow rather than a lump sum, adjusting withholding or contributions can free up money without a taxable event. The 401(k) contribution calculator shows how a deferral change moves your paycheck, the Roth vs traditional 401(k) calculator covers where future dollars should go, and the tax refund estimator tells you whether you're already over-withholding.

Estimates only. Not tax, legal, or investment advice. This tool assumes an all-pre-tax balance and a lump-sum cash-out paid to you with 20% federal withholding. It uses the 2026 standard deduction and doesn't model itemized deductions, credits, or other adjustments. State figures are state income tax liability, not state withholding. A few states, notably California, add their own early-distribution penalty that isn't modeled here. Capped exceptions (birth or adoption, disaster, emergency expense, domestic abuse) shelter only the capped amount, while this tool treats an exception as waiving the penalty on the full withdrawal.
Frequently Asked Questions
Common questions about 401(k) early withdrawal tax calculator
How much tax do you pay on a 401(k) early withdrawal?
A withdrawal before age 59.5 gets billed twice. It's added to your ordinary income and taxed at your marginal federal rate (10% to 37% in 2026), then hit with a 10% additional tax under IRC 72(t), plus state income tax in the 41 states (and DC) that tax income. A $20,000 withdrawal for someone in the 22% bracket in a 5% state runs roughly $4,400 federal, $2,000 penalty, and $1,000 state, so about $7,400 in total and around $12,600 kept. Run your own numbers above, then check the filing side with the tax refund estimator.
Is the 20% withheld from my 401(k) the tax I owe?
No. The 20% is mandatory federal withholding on an eligible rollover distribution paid to you (IRC 3405(c)). It's a prepayment, exactly like the withholding on your paycheck. Your actual bill is income tax plus the 10% penalty plus state tax, and the plan withholds neither the penalty nor state tax. Most people under 59.5 end up owing more at filing rather than getting a refund.
Does a hardship withdrawal avoid the 10% penalty?
No, and this is the most common misconception about 401(k) withdrawals. A hardship distribution is a plan rule about whether you're allowed to take the money out. It's not an exception to the 10% additional tax, and Form 5329 has no hardship exception code. You owe the 10% unless your situation independently qualifies, for example unreimbursed medical expenses above 7.5% of AGI or a federally declared disaster.
What is the rule of 55?
If you leave your job (quit, laid off, or fired) in or after the calendar year you turn 55, distributions from that employer's 401(k) escape the 10% penalty. The threshold is age 50, or 25 years of service, for qualified public safety employees. It applies only to qualified employer plans and never to IRAs, so rolling the balance into an IRA first destroys the exception, and it doesn't reach 401(k) balances left at earlier employers.
Which exceptions actually waive the 10% penalty on a 401(k)?
Separation from service at 55 or later, total and permanent disability, substantially equal periodic payments under 72(t), unreimbursed medical expenses above 7.5% of AGI, a QDRO, an IRS levy, qualified birth or adoption (up to $5,000 per child), terminal illness, domestic abuse, a federally declared disaster, an emergency personal expense (up to $1,000), and qualified reservist distributions. First-time home purchase, higher education, and health insurance while unemployed are IRA-only and never apply to a 401(k). Every exception waives the penalty only. The money is still ordinary income.
Do I pay Social Security and Medicare tax on a 401(k) withdrawal?
No. Your contributions were already subject to the 6.2% Social Security and 1.45% Medicare tax when they came out of your paycheck (IRC 3121(v)(1)(A)). Distributions are income-taxable only, so there's no FICA on the way out. That's why this calculator shows no FICA line, unlike the 401(k) contribution calculator, where FICA still applies to deferrals.
Can I avoid the penalty by paying the money back?
Generally no, but if you act within 60 days you can roll the distribution into an IRA or another plan and undo the whole thing: no income tax, no penalty. The catch: you have to replace the 20% the plan withheld out of your own pocket to roll over the full amount, otherwise that 20% is treated as a taxable, penalized distribution. Birth or adoption and disaster distributions have their own longer repayment windows.
How much does an early withdrawal really cost me at retirement?
Beyond the tax, you lose the compounding. $20,000 withdrawn at 35 and left alone until 65 at a 7% annual return would have grown to roughly $152,000. That's the number worth weighing against a 401(k) loan or any other source of cash. If you're choosing where future contributions go instead, the Roth vs traditional 401(k) calculator covers that side.
