The 457(b) is the one employer retirement plan with no 10% early-withdrawal penalty — and it is also the plan most often ruined by a single rollover. Move a governmental 457(b) into an IRA after leaving your job and every dollar of that money becomes subject to the 10% penalty until age 59½. This tool shows the penalty, the tax and the net cash for a 457(b) withdrawal, a 457(f) payout, and the same balance after an IRA rollover.
Every row is computed by the page's own penaltyOn() and withholding() functions at a 24% federal and 5% state rate. The first three rows are the same $60,000 withdrawal from the same balance — the only difference is the plan type, and the penalty column is the entire story of why 457(b) planning goes wrong.
| Plan & situation | Age | Withdrawal | 10% penalty | Tax (fed + state) | Net cash | Effective cost |
|---|---|---|---|---|---|---|
| Governmental 457(b), separated | 52 | $60,000 | $0 | $17,400 | $42,600 | 29.00% |
| Tax-exempt 457(b), separated | 52 | $60,000 | $0 | $17,400 | $42,600 | 29.00% |
| Same money rolled to an IRA | 52 | $60,000 | $6,000 | $17,400 | $36,600 | 39.00% |
| 457(b), age 61 — no penalty anyway | 61 | $90,000 | $0 | $26,100 | $63,900 | 29.00% |
| 457(b) while still employed | 52 | $60,000 | $6,000 | $17,400 | $36,600 | 39.00% |
| 457(f) vesting payout | 52 | $60,000 | $0 | $17,400 | $42,600 | 29.00% |
A governmental 457(b) is penalty-free at any age once you separate from service. A tax-exempt (nonprofit) 457(b) is also penalty-free — the 10% rule in IRC §72(t) simply does not apply to 457(b) plans. A 457(f) payout is not a retirement plan distribution at all: it is ordinary compensation, taxed in full when the substantial risk of forfeiture lapses, with no penalty and no rollover option.
Section 457(b) plans are deferred compensation, not qualified retirement plans. That single structural difference is why IRC §72(t)'s 10% additional tax does not apply: the penalty is imposed on early distributions from qualified plans and IRAs, and a 457(b) is neither. A 45-year-old who leaves a city job can take the entire 457(b) balance and owe only ordinary income tax.
If a governmental 457(b) distribution is an eligible rollover distribution and you take it payable to yourself, the plan must withhold 20% federal. That withholding is a prepayment, not a penalty — it is credited on your return. Elect a direct rollover to avoid it entirely, or plan for a smaller cheque than you requested.
The classic FIRE sequence of withdrawals assumes a five-year gap between retiring and age 59½ that has to be bridged with taxable brokerage money, Roth conversions or a 72(t) program. A governmental 457(b) closes that gap more cheaply than any of them: withdraw exactly what you need, pay ordinary income tax at what may be a lower marginal rate, and owe no 10% penalty at all.
Run the numbers for a $60,000 withdrawal at age 52 in the 24% bracket with a 5% state rate. From a governmental 457(b) the cost is $17,400 and you keep $42,600. The same $60,000 from an IRA costs $23,400 once the 10% penalty is added, leaving $36,600 — a difference of $6,000 on a single withdrawal. Repeat that for four years of an early retirement and the rollover decision is worth more than most people save in a decade of fund fees.
The contribution limit is shared across all of them: $23,500 of employee deferrals in 2026, plus the age-50 catch-up. But the 457(b) has two features the others do not. First, the special age-50 catch-up for governmental plans allows up to double the normal limit in the three years before normal retirement age, subject to unused prior-year capacity. Second, and more importantly, a governmental 457(b) can be used alongside a 401(k) or 403(b) with a separate deferral limit — an employee of a public university with both a 403(b) and a 457(b) can defer $23,500 into each, $47,000 combined.
The trade-off is creditor and employer risk. A tax-exempt 457(b) holds assets that remain the employer's property until distributed, so they are exposed to the nonprofit's creditors — unlike a 401(k) trust. Governmental 457(b) assets must be held in trust for the exclusive benefit of participants and are not exposed that way. If your employer is a financially stressed nonprofit, that distinction matters more than the penalty rule.

It does not model bracket stacking, the 3.8% net investment income tax, state-specific treatment of governmental 457(b) distributions, or plan-specific in-service withdrawal provisions.
