457(b) vs 403(b): Which One Should You Fund First?
If your employer offers both, fund the 403(b) up to the full employer match first, then send the rest to a governmental 457(b), because a governmental 457(b) is the only one of the two you can spend before age 59 1/2 without the 10% early-withdrawal tax.
The two plans do not share a contribution limit. In 2026 you can defer $24,500 to each, or $49,000 combined, before any catch-up contributions. Most of the rest looks alike: pre-tax or Roth contributions, tax-deferred growth, and required withdrawals starting at 73.
The differences that decide the order are early access, catch-up rules, and, for one version of the 457(b), whether the money is legally yours at all.
457(b) vs 403(b): Side-by-Side
| 457(b) | 403(b) | |
|---|---|---|
| Who offers it | State and local governments, plus "top-hat" plans at some hospitals and 501(c)(3) employers | Public schools, colleges, churches, and 501(c)(3) nonprofits |
| 2026 contribution limit | $24,500, on a limit of its own | $24,500, shared with any 401(k) or TSP you also use |
| Catch-up provisions | $8,000 at 50+ ($11,250 at ages 60 to 63) in governmental plans only; special 3-year rule up to 2x the limit | $8,000 at 50+ ($11,250 at ages 60 to 63); 15-year service rule up to $3,000 a year, $15,000 lifetime |
| Early-withdrawal penalty | None on governmental 457(b) money once you separate from the employer, at any age | 10% additional tax before 59 1/2 unless an exception applies |
| Investment menu | Set by the sponsoring employer; usually mutual funds and annuities | Annuity contract, mutual fund custodial account, or church retirement income account |
| Employer match | Less common, and employer money counts against your same $24,500 cap | More common, and a match does not reduce your own $24,500 deferral limit |
| Creditor protection | Governmental: contributions go into a trust. Non-governmental: employer property, reachable by its creditors | Held for you in an annuity contract or custodial account, not owned by the employer |
| Required minimum distributions | Generally start at 73; can be delayed while you still work there | Generally start at 73; can be delayed while you still work there |
Which should you choose?
Fund the 403(b) up to the full employer match, then put everything else into the governmental 457(b) until you have hit your savings target for the year. The match is a guaranteed return nothing else matches, and the 457(b) is the account you can actually spend before 59 1/2 without a penalty.
If the 403(b) has no match, or you expect to stop working before 59 1/2, start with the governmental 457(b) instead. Flip the rule entirely if your 457(b) is a non-governmental top-hat plan: there the 403(b) goes first, and any top-hat deferral should be treated as an unsecured claim on your employer rather than as safe retirement money.
The 10% penalty rule reverses the usual funding order
A 403(b) counts as a qualified retirement plan for early-withdrawal purposes. Pull money out before age 59 1/2 and you generally owe a 10% additional tax on top of ordinary income tax.
A governmental 457(b) sits outside that rule. IRS Topic no. 558 says an eligible state or local government 457 plan is not a qualified retirement plan, so distributions from it are not hit with the 10% additional tax. Your age never enters the test. What matters is that the plan allows the distribution, which it generally does once you separate from the employer.
Picture a school district employee who retires at 55 and needs income for four years. The governmental 457(b) pays out at ordinary income tax rates with no penalty. The 403(b) needs an exception. Two commonly fit: separating from service with that employer after reaching age 55, or taking substantially equal periodic payments over your life expectancy. Both are real, and both carry conditions that are easy to break.
This is why "always chase the match first" can be the wrong rule for an early retiree. If you need bridge income in your 50s, penalty-free access can be worth more than a small match. If you plan to work to 65, the penalty difference never comes up and the match wins outright. Model the gap years with the early retirement calculator, and see what a penalized withdrawal actually costs in the 401(k) early withdrawal calculator.
You can max out both in the same year
The 403(b) limit is a shared limit. If you also have a 401(k) or the federal TSP, one pot of $24,500 in 2026 covers all of them together.
A 457(b) is not in that pot. The IRS states that you have a separate deferral limit if you also participate in a 457(b) plan, and that it is not combined with deferrals to a 403(b) or other plans.
For a hospital or university employee offered both, that means $24,500 into the 403(b) and $24,500 into the 457(b), or $49,000 of deferrals out of one paycheck in 2026. At 50 or older in a governmental plan, each account can also take the $8,000 catch-up on top.
One asymmetry to watch. In a 457(b), the annual limit applies to total contributions and other additions to your account, so employer money eats into your own room. In a 403(b), an employer match does not reduce your $24,500 elective deferral limit. Use the 401(k) calculator to model the same deferral math, or the retirement savings calculator for the full picture.
The catch-up rules are not the same
Both plans allow the standard age-50 catch-up of $8,000 in 2026, and $11,250 instead for ages 60 to 63. After that they diverge.
One 2026 change hits high earners in both accounts at once. Beginning in 2026, the IRS requires participants whose prior-year wages with the plan sponsor topped $150,000 to make catch-up contributions on a Roth basis. That threshold is adjusted for inflation and rose from $145,000. It covers most 401(k), 403(b), and governmental 457 plans, so it can apply to your 403(b) catch-up and your 457(b) catch-up in the same year. You do not lose the $8,000. It simply stops reducing your taxable income, in each account. If you are near that wage line, ask your plan how it is applying the rule before you set your deferral.
The 403(b) adds the 15-year service rule. Employees with 15 or more years at a public school system, hospital, home health service agency, health and welfare service agency, or church can defer up to $3,000 more per year, capped at $15,000 over a career. It is actually the lesser of three tests, so ask your plan to run your number. The IRS also fixes the order: deferrals above the standard limit apply to the 15-year catch-up first, then to the age-50 catch-up.
The governmental 457(b) adds a different one. In the three years before the plan's normal retirement age, you can defer up to twice the standard limit, which is 2 x $24,500, or $49,000, in 2026. The extra room is capped at the contribution room you left unused in earlier years. You cannot combine the special 3-year catch-up with the age-50 catch-up in the same year; you use whichever produces more.
The practical read: the 403(b) rule rewards long tenure, the 457(b) rule rewards someone who under-saved early and is closing in on the plan's retirement age. A long-serving employee near retirement can qualify for one in each account in the same year.
A non-governmental 457(b) is a different product entirely
Not every 457(b) is governmental. Hospitals, private universities, and other tax-exempt employers can offer a non-governmental 457(b), usually called a top-hat plan. The IRS limits it to a select group of management or highly compensated employees, so most staff never see one.
Two features make it far riskier than the 403(b) sitting beside it. First, the IRS states that plan assets are not held in trust for employees and remain the property of the employer, available to its general creditors in litigation or bankruptcy. You become an unsecured creditor of your own employer for pay you already earned. Second, the age-50 catch-up is not allowed in a non-governmental 457(b) at all, though the special 3-year catch-up is.
Your 403(b) money is not exposed that way. It sits in an annuity contract or a mutual fund custodial account held for you.
So the answer flips with the plan type. Against a governmental 457(b), the 403(b) is the more restricted account. Against a top-hat 457(b), the 403(b) is the safer account, and a large top-hat deferral is a bet that your employer is still solvent a decade from now. Check the plan document or ask HR which type you have before you raise your deferral. The 403(b) vs 401(k) breakdown covers the 403(b)'s own fee and ERISA quirks, and 457(b) vs 401(k) covers the same 457(b) split against a private-sector plan.
Moving money between them can erase the penalty exemption
A governmental 457(b) can accept rollovers from a 403(b), and it can roll out to an IRA or a new employer's plan. That flexibility hides a trap most summaries skip.
Money that lands in a 457(b) from a 403(b), 401(k), or IRA keeps its old character. The IRS says amounts in a 457 plan that came from a direct transfer or rollover of a qualified plan are still subject to the 10% additional tax on early distributions. Consolidating your 403(b) into your 457(b) before an early retirement does not launder it into penalty-free money. Plans normally track those balances separately.
The reverse costs you too. Roll a governmental 457(b) into an IRA and IRA rules take over, and IRA withdrawals before 59 1/2 do face the 10% additional tax unless an exception applies. If early access is the reason you funded the 457(b), leaving it in the plan can be worth more than any fund-menu upgrade an IRA offers.
On required withdrawals the two land in the same place. Each generally begins at age 73, and each lets you delay while you are still working for that employer. Roth money inside a 403(b) has no required withdrawal during the owner's lifetime. The RMD calculator handles either account, and the retirement hub links the rest of the tools.
Frequently asked questions
457(b) vs 403(b): which one is better?
A governmental 457(b) is better for anyone who may need the money before age 59 1/2, because its distributions avoid the 10% early-withdrawal tax at any age once you leave the job. A 403(b) is better when it carries the employer match, since the match is a return the 457(b) cannot beat. If both are offered, fund the match first and the 457(b) next.
Can I contribute to both a 457(b) and a 403(b) in the same year?
Yes, and you get the full limit in each. The IRS treats the 457(b) deferral limit as separate and does not combine it with 403(b) deferrals. In 2026 that is $24,500 into each account, or $49,000 total, plus any catch-up contributions you qualify for. One catch: beginning in 2026, if your prior-year wages with the plan sponsor topped $150,000, those catch-up contributions must be made on a Roth basis in both accounts.
Can I withdraw from a 457(b) before 59 1/2 without a penalty?
Yes, from a governmental 457(b). The IRS does not treat an eligible state or local government 457 plan as a qualified retirement plan, so distributions are not subject to the 10% additional tax on early distributions, whatever your age. You still owe ordinary income tax, and the plan still has to permit the distribution, which usually requires separation from employment.
Which is better for early retirement, a 457(b) or a 403(b)?
A governmental 457(b) generally wins for early retirement. It funds the years between leaving work and 59 1/2 without a penalty, while a 403(b) needs an exception such as separating from service after age 55 or taking substantially equal periodic payments. Do not roll the 457(b) into an IRA first, since that would put the money back under the 10% rule.
What is the difference between a governmental and non-governmental 457(b)?
A governmental 457(b) is sponsored by a state or local government and holds contributions in trust for participants. A non-governmental, or top-hat, 457(b) is offered by a tax-exempt employer to a select group of management or highly compensated employees, and the IRS states its assets remain the employer's property and are available to its general creditors in litigation or bankruptcy. The non-governmental version also cannot offer the age-50 catch-up.
Do 457(b) and 403(b) plans have required minimum distributions?
Yes. Both are subject to required minimum distributions generally starting at age 73, and both let you delay while you are still working for the employer that sponsors the plan. Roth money inside a 403(b) is not subject to required withdrawals during the owner's lifetime.
