403(b) and 401(k) Withdrawals: Rules, Penalties, and Exceptions
Early withdrawal rules, the rule of 55, loans, hardship withdrawals, RMDs, and a comparison of 403(b) vs 401(k) mechanics. Updated 17 April 2026.
Early withdrawal (before age 59.5)
Default: 10% penalty plus ordinary income tax
Any distribution from a traditional 403(b) or 401(k) before age 59.5 is subject to 10% early withdrawal penalty plus ordinary income tax at your marginal rate. On $30,000 withdrawn at a 22% bracket: $3,000 penalty + $6,600 income tax = $9,600 gone. You net $20,400 from $30,000. This is why the rule is almost always: do not cash out.
Exceptions to the 10% penalty
Income tax still applies even when the 10% penalty is waived. These exceptions only eliminate the extra 10% penalty.
Death
Distributions to beneficiaries upon account holder's death are exempt from the 10% penalty.
Disability
Total and permanent disability. Must be unable to engage in any substantial gainful activity.
Medical expenses
Unreimbursed medical expenses exceeding 7.5% of adjusted gross income.
Substantially Equal Periodic Payments (SEPP / 72(t))
Series of equal payments over 5 years or until age 59.5, whichever is longer. Complex calculation methods; get professional advice.
Rule of 55
Separation from service in the year you turn 55 (50 for qualified public safety employees). Only applies to that employer's plan, not IRAs.
Qualified domestic relations order (QDRO)
Distributions to an alternate payee (former spouse) under a court order incident to divorce.
Qualified birth or adoption
Up to $5,000 per birth or adoption event. Must repay within 3 years to avoid it being treated as a distribution.
Emergency personal expense
Up to $1,000 once per year for unforeseeable emergency. SECURE 2.0 provision. 3-year repayment window.
Domestic abuse victim
Up to $10,000 or 50% of vested balance (whichever is less) within one year of being a domestic abuse victim. SECURE 2.0.
Federally declared disaster
Up to $22,000 from retirement accounts in federally declared disaster areas. SECURE 2.0.
Terminal illness
Certified terminal illness with life expectancy of 84 months or less. SECURE 2.0.
Rule of 55
If you leave your employer in the calendar year you turn 55 (or after), you can take distributions from that employer's 403(b) or 401(k) without the 10% penalty. You still owe income tax. The rule applies only to that specific plan, not to IRAs or previous-employer plans.
For qualified public safety employees (police, fire, EMS), the rule applies at age 50. Some governmental 403(b) plans extend additional in-service withdrawal rights at earlier ages.
Plan loans
Required Minimum Distributions (RMDs)
Under SECURE 2.0, RMDs begin at age 73. Both 403(b) and 401(k) traditional accounts are subject to RMDs. Roth 401(k) and Roth 403(b) accounts are exempt from RMDs during the owner's lifetime (effective for 2024 tax year and beyond).
Missing an RMD: a 25% excise tax on the amount not distributed (reduced to 10% if corrected within 2 years). The IRS has streamlined the correction process under SECURE 2.0 but the best approach is to not miss the RMD in the first place.
