In short
An early 401(k) or IRA withdrawal before 59½ is taxed as ordinary income at your marginal rate plus a 10% additional tax, and most states tax it too — $30,000 taken at 42 on $70,000 of other income costs about $6,600 federal, $3,000 penalty and $1,500 state, leaving $18,900; the plan withholds 20% up front, and the penalty (never the income tax) is waived for the rule of 55, 72(t) payments, disability, medical costs over 7.5% of AGI, $1,000 emergencies, $5,000 births, $10,000 domestic abuse and $22,000 disasters.
Who this is for: Anyone under 59½ weighing a hardship or emergency withdrawal, people who left a job at 55–59 checking the rule of 55, and those comparing a withdrawal with a 401(k) loan.
What an early 401(k) or IRA withdrawal really costs
A pre-tax withdrawal before age 59½ is hit three times: it is ordinary income stacked on top of everything else you earn that year (so it is taxed at your marginal rate, often pushing you into the next bracket), it carries a 10% additional tax under IRC §72(t), and most states tax it too. The plan also withholds 20% from a 401(k) distribution up front — which is rarely the full bill, so more is due in April.
The penalty — never the income tax — is waived in listed cases: leaving your employer in or after the year you turn 55 (the "rule of 55", plans only), a 72(t) series of equal payments, disability, medical bills over 7.5% of AGI, and the SECURE 2.0 exceptions of $1,000 a year for emergencies, $5,000 per birth or adoption, $10,000 for domestic-abuse victims and $22,000 after a federal disaster. The calculator applies the right cap and shows what the money would have grown to if left alone — usually the largest number on the page.

Assumptions
- Federal tax = tax on (other taxable income + withdrawal) minus tax on other income, 2026 brackets; the withdrawal is fully taxable (pre-tax account).
- 10% additional tax on the non-exempt portion; dollar-capped exceptions ($1,000 / $5,000 / $10,000 / $22,000) exempt only up to the cap; the rule of 55 applies to employer plans, not IRAs.
- Flat state rate you enter; 20% plan withholding or 10% IRA default withholding shown as a prepayment, not the final bill.
- Lost growth = amount × 1.07^years; Roth option taxes only the earnings portion you enter.
Worked example
Federal tax on the extra $30,000: $70,000 + $30,000 = $100,000 of taxable income stays inside the 22% bracket (which runs to $105,700), so all of it is taxed at 22% → federal $6,600. Penalty 10% = $3,000. State 5% = $1,500. Total $11,100, an effective cost of 37%; $18,900 kept. The plan withholds $6,000, so $5,100 more is due at filing. Left invested for 23 years at 7%, the $30,000 would have become about $142,000.
Frequently asked questions
Is the 10% penalty on top of income tax?
Yes. Income tax applies to the whole pre-tax amount at your marginal rate, and the 10% is an additional tax unless an exception applies.
What is the rule of 55?
If you leave your employer in or after the calendar year you turn 55 (50 for police, firefighters, EMTs and some federal employees), withdrawals from that employer's 401(k) are penalty-free. It does not cover IRAs or older employers' plans.
Does the 20% withholding mean I only owe 20%?
No. 20% is a prepayment the plan must withhold on 401(k) distributions; your real bill is your marginal rate plus the penalty, settled on your tax return.
Can I take $1,000 for an emergency without penalty?
Yes, once per calendar year since 2024, if your plan allows it; you can repay it within three years, and a second one is blocked until you do.
Is a 401(k) loan better?
Usually, if you stay employed: no tax, no penalty, and you repay yourself with interest. If you leave the job the balance is generally due by the tax-filing deadline or it becomes a taxable distribution.
Do Roth withdrawals get penalised?
Contributions never; earnings withdrawn before 59½ and before the account is five years old are taxed and penalised unless an exception applies.
Can I repay an emergency or birth withdrawal?
Yes — both can be repaid within three years to restore the balance and recover the tax; the $1,000 emergency withdrawal cannot be repeated until repaid or three years pass.
Does the penalty apply to a 457(b) plan?
No. Governmental 457(b) plans are exempt from the 10% additional tax on their own contributions, though rolled-in 401(k) money keeps it.
