457(b) vs Roth IRA: Pre-Tax, After-Tax, and Which to Fund Next
A 457(b) and a Roth IRA are not an either/or choice, because their contribution limits are completely separate. For 2026 you can defer up to $24,500 into a 457(b) and still put $7,500 into a Roth IRA in the same year, as long as your income sits below the Roth IRA phase-out range.
The real decision is not which account to pick. It is which one earns the next dollar once you understand two things: a governmental 457(b) escapes the 10% early-withdrawal penalty entirely after you leave the job, and a Roth IRA lets you pull your own contributions back out at any time.
457(b) vs Roth IRA: Side-by-Side
| 457(b) | Roth IRA | |
|---|---|---|
| 2026 contribution limit | $24,500 elective deferral; $32,500 at 50+ and $35,750 at ages 60-63 in governmental plans only | $7,500; $8,600 at 50 or older |
| Income limit to contribute | None - your salary does not lock you out | Phases out $153,000-$168,000 single and $242,000-$252,000 married filing jointly (2026) |
| Tax treatment | Pre-tax by default; many governmental plans also offer a designated Roth option | After-tax only; qualified withdrawals are tax-free |
| Early-withdrawal penalty | None on governmental 457(b) money, at any age, once you separate from the employer | Your contributions come out anytime penalty-free; earnings face 10% before 59 1/2 unless an exception applies |
| Required minimum distributions | Yes at 73 on pre-tax balances; designated Roth balances have none while you are alive | None while the owner is alive |
| Investment menu | Limited to the fund lineup your plan chose | Nearly anything your brokerage offers |
| Employer money | Some plans allow it, but employer dollars count toward the same annual limit | None - it is your own individual account |
| Creditor protection | Governmental plans hold assets in trust; non-governmental top-hat plans stay employer property and are open to its general creditors | Held at your own custodian, with no exposure to any employer's creditors |
Which should you choose?
Fund both if you can. The two limits do not overlap, so treating this as a single choice leaves room on the table. If you can only fund one, a simple rule works for most public-sector savers: take any employer contribution in the 457(b) first, then fill the Roth IRA, then come back and push the 457(b) toward its limit.
Two details can flip that order. If you plan to stop working well before 59 1/2, weight the 457(b) more heavily, since a governmental plan pays out penalty-free at any age after separation. If your plan is a non-governmental "top-hat" 457(b), fill the Roth IRA first, because top-hat balances sit inside your employer's credit risk. See 457(b) vs 401(k) for how the 457(b) stacks against a workplace plan, and 401(k) vs Roth IRA for the broader match-first sequence.
The limits are separate, so this is rarely an either/or
The 457(b) elective deferral limit and the IRA limit live in different parts of the tax code. They do not share a cap. For 2026 the IRS sets the 457(b) deferral limit at $24,500 and the IRA limit at $7,500. Savers 50 and older can add an $8,000 catch-up in a governmental plan and $1,100 in the IRA. Workers aged 60 through 63 get a larger plan catch-up of $11,250 instead.
The IRS is direct about the overlap: "You can contribute to a traditional or Roth IRA even if you participate in another retirement plan through your employer or business." A teacher, city worker, or state employee can max the 457(b) and still open a Roth IRA that same year.
That matters more than most comparisons admit. Readers often arrive asking which account is better, then never fund the second one. Model the combined number in the retirement savings calculator before you decide either is off the table.
Many 457(b) plans now have a Roth option, which changes the question
The pre-tax versus after-tax framing often falls apart once you read your plan documents. Per the IRS, "a governmental 457(b) plan may be amended to allow designated Roth contributions and in-plan rollovers to designated Roth accounts." Plenty of state and local plans have done exactly that.
If yours has, you are not choosing between pre-tax and after-tax at all. You can choose Roth treatment inside the 457(b) and get the after-tax outcome with a much larger limit. The comparison then narrows to investment menu, early access, and where your money is legally held.
This option is limited to governmental plans. A non-governmental tax-exempt 457(b) cannot offer designated Roth contributions. Check your plan's summary description, or ask your benefits office directly, before assuming your only after-tax route is an IRA. For how a plan-level Roth account compares to an IRA, see Roth IRA vs Roth 401(k) - the same tradeoffs apply.
The 457(b) early-withdrawal rule is unusually generous
A governmental 457(b) is one of the few retirement accounts with no 10% early-withdrawal penalty. The IRS states that "an eligible state or local government section 457 deferred compensation plan isn't a qualified retirement plan and any distribution from such plan isn't subject to the 10% additional tax on early distributions."
Once you separate from the employer, you can take distributions at 45, 50, or any age. You owe ordinary income tax, but no penalty. That makes a 457(b) an unusually good bridge for anyone retiring before 59 1/2. A Roth IRA cannot match this for earnings - those still face the 10% additional tax before 59 1/2 unless an exception applies.
One caveat the IRS names and most articles skip: money rolled into a 457(b) from a 401(k), 403(b), or IRA keeps its original penalty exposure. Consolidating old accounts into your 457(b) does not launder them into penalty-free status. Keep rollover dollars in a separate source bucket if early access is the plan. The early retirement calculator can show how many bridge years you would need to cover.
Roth IRA contributions are the most liquid retirement dollars you own
This is the axis most comparisons miss. Roth IRA distributions follow ordering rules: your regular contributions come out first, then converted amounts, then earnings. Because you already paid tax on those contributions, they come back out tax-free and penalty-free at any age, for any reason. Publication 590-B from the IRS lays out this sequence.
The middle bucket carries a trap worth naming. Each Roth conversion starts its own separate 5-year clock. Pull converted dollars out before that clock runs and before you turn 59 1/2, and you owe the 10% additional tax on them, even though you already paid income tax at conversion. Your regular contributions never have that problem. Converted money does, conversion by conversion.
So a Roth IRA does double duty. It is a retirement account and a deep backup reserve. Contribute $7,500 this year and that $7,500 stays reachable, even if the account's growth does not.
A 457(b) works differently. You generally cannot touch it while still employed there, outside narrow plan rules. Its flexibility arrives after you leave. That is the honest split: the Roth IRA is liquid while you are working, and the governmental 457(b) is liquid once you are not. If you want the older pre-tax and after-tax comparison in IRA form, see Roth IRA vs Traditional IRA.
Required minimum distributions push in opposite directions
Pre-tax 457(b) balances are subject to required minimum distributions. The IRS applies RMD rules to "all employer sponsored retirement plans, including profit-sharing plans, 401(k) plans, 403(b) plans, and 457(b) plans," and withdrawals generally start at age 73.
A Roth IRA has no such requirement. The IRS confirms that "the RMD rules do not apply to Roth IRAs or Designated Roth accounts while the owner is alive." You control the timing for as long as you live, and beneficiaries take over the distribution rules afterward.
The practical effect is on your taxable income late in retirement. Forced 457(b) withdrawals stack on top of Social Security and any pension. A Roth IRA gives you a bucket you can leave alone in a high-income year. If your plan offers designated Roth contributions, those balances also avoid lifetime RMDs. Project the withdrawal side in the Roth IRA calculator.
A non-governmental 457(b) carries a risk a Roth IRA never does
Not every 457(b) is a government plan. Hospitals, universities, and other tax-exempt employers offer "top-hat" 457(b) plans to a select group of management or highly compensated employees. The legal structure is fundamentally different.
The IRS is blunt about it: "Plan assets are not held in trust for employees but remain the property of the employer (available to its general creditors in the event of litigation or bankruptcy)." Some employers use a rabbi trust, but the plan stays unfunded and the money stays reachable by creditors. Top-hat plans also lose the age-50 catch-up, which the IRS allows only in governmental 457(b) plans, so the headline catch-up numbers you read elsewhere may not apply to you at all.
A Roth IRA has no equivalent exposure. It sits at your own custodian, in your own name, disconnected from any employer's balance sheet. If your 457(b) is non-governmental, that argues for funding the Roth IRA first and for limiting how much of your net worth you let sit inside one employer's credit. Ask your benefits office which type your plan is - the answer changes the analysis on this page more than any tax bracket does. Start with the retirement hub to see how the pieces fit together.
Frequently asked questions
457b vs Roth IRA: which should I fund first?
Fund both if your budget allows, since the limits are separate. If you must choose, most public-sector savers take any employer contribution in the 457(b) first, then fill the Roth IRA, then return to the 457(b). Lean toward the 457(b) if you plan to retire before 59 1/2, and toward the Roth IRA if your plan is a non-governmental top-hat 457(b).
Can I contribute to a 457(b) and a Roth IRA in the same year?
Yes. The two accounts have entirely separate limits. For 2026 that is $24,500 in a 457(b) and $7,500 in a Roth IRA, so you can max both, as long as your income is under the Roth IRA phase-out range of $153,000 to $168,000 for single filers or $242,000 to $252,000 for married couples filing jointly.
Is a 457(b) pre-tax or after-tax?
Usually pre-tax, but not always. A governmental 457(b) plan can be amended to allow designated Roth contributions, per the IRS, which means after-tax treatment inside the plan. Non-governmental tax-exempt 457(b) plans cannot offer that option. Check your plan's summary description rather than assuming.
Can I withdraw from a 457(b) before 59 1/2 without a penalty?
Yes, for a governmental 457(b), once you have separated from that employer. The IRS states that distributions from an eligible state or local government 457 plan are not subject to the 10% additional tax on early distributions. You still owe ordinary income tax. Money rolled in from a 401(k), 403(b), or IRA keeps its original 10% penalty exposure.
Can I take my Roth IRA contributions out early?
Yes. Roth IRA ordering rules pull your regular contributions out first, and those come out tax-free and penalty-free at any age, no matter how old the account is. Earnings work differently. A withdrawal of earnings is qualified only if the account has met the 5-year holding period and you are 59 1/2 or older, or the distribution is for death, disability, or a first home. Miss either half of that test and the earnings are taxable and generally face the 10% additional tax, so an old Roth does not make earnings safe to touch at 40.
What happens to my 457(b) if my employer goes under?
It depends on the plan type. Governmental 457(b) assets are held in trust for participants. Non-governmental top-hat 457(b) assets remain the property of the employer and are available to its general creditors in litigation or bankruptcy, per the IRS. A Roth IRA has no such exposure because it is held in your own name at your own custodian.
