What Are the Disadvantages of a 457(b) Plan?

The disadvantages of a 457(b) plan depend heavily on whether the plan is governmental or non-governmental, and the non-governmental version carries risks that no other common retirement account shares. Participants can lose their entire balance if the employer becomes insolvent, face severe restrictions on moving the money when they leave, pay Social Security and Medicare taxes years before they can touch a dollar of it, and run into withdrawal rules that are stricter than a 401(k)’s. Governmental plans avoid the worst of these, but even they come with trade-offs worth understanding before you defer another paycheck.

Non-Governmental Plan Balances Can Be Taken by Creditors

This is the single biggest problem with a non-governmental 457(b), and most participants don’t realize it applies to them. To keep its tax-deferred status, the plan must remain “unfunded,” meaning the money you defer legally belongs to your employer until distribution, not to you.¹

Most employers park these deferrals in a “rabbi trust,” which segregates the money administratively but does nothing in a bankruptcy. If your tax-exempt employer fails or loses a major lawsuit, the assets in the rabbi trust are available to the employer’s general creditors, and employees stand behind those creditors in priority.¹ The entire balance can disappear.

Governmental 457(b) plans do not carry this risk. They are required to hold assets in trust for the exclusive benefit of participants, which shields the money from the employer’s creditors.² 401(k) participants get similar protection under ERISA.³ Only the non-governmental 457(b) leaves participants exposed this way.

Rollovers Are Severely Limited

Leaving a job usually means a decision about what to do with your retirement account. With a non-governmental 457(b), that decision is largely made for you. Rollovers to IRAs, 401(k)s, 403(b)s, and even governmental 457(b) plans are not permitted.²

The only tax-free move is a direct plan-to-plan transfer to another non-governmental 457(b), and both plans must specifically allow it. Landing at a new tax-exempt employer whose plan accepts incoming transfers is rare. For most people leaving the nonprofit sector, the practical result is a forced lump-sum distribution, with the entire balance taxed as ordinary income in one year. That can push you into a much higher bracket the year you leave.

Governmental 457(b) plans allow rollovers to IRAs, 401(k)s, 403(b)s, and other governmental 457(b) plans.² But rolling those funds into an IRA or 401(k) costs you one of the plan’s best features: 457(b) distributions after separation are not subject to the 10% early withdrawal penalty that applies to 401(k) and IRA distributions before age 59½. The moment the money moves, that penalty attaches. Anyone planning to tap savings before 59½ should think hard before rolling over.

FICA Taxes Apply Before You See the Money

Deferring salary into a 457(b) postpones income tax, but not Social Security and Medicare tax. Under the FICA special timing rule, deferred amounts are taxed for FICA purposes at the later of when you perform the services or when the right to the money vests.⁴ Because 457(b) deferrals are almost always immediately vested, FICA hits your paycheck in the year you earn the money.

You pay Social Security tax at 6.2% and Medicare tax at 1.45% now, then income tax later when you draw the funds. It’s not a hidden trap so much as an overlooked cost that can change how much you decide to defer, especially if you’re already near or above the Social Security wage base.

No Roth Option for Non-Governmental Plans

Governmental 457(b) plans can offer Roth contributions, letting participants pay tax now and take distributions tax-free later. Non-governmental plans cannot.² For nonprofit employees who expect a higher tax bracket in retirement, that closes a planning door 401(k) and 403(b) participants routinely walk through.

Contribution Cap Quirks

For 2026, the standard deferral limit is $24,500, matching the 401(k) figure.⁵ The headline number looks fine. The complications sit in the fine print.

You Can’t Combine Catch-Ups

Participants aged 50 and older can add $8,000 in catch-up contributions, reaching $32,500. Those turning 60, 61, 62, or 63 in 2026 can add $11,250 instead under SECURE 2.0, reaching $35,750.⁵ The 457(b) also offers a special three-year pre-retirement catch-up that lets you defer up to double the standard limit — $49,000 in 2026 — during the three years before the plan’s designated normal retirement age. You cannot use both the age-based catch-up and the special three-year catch-up in the same year. You have to choose.⁶ The choice depends on how much you underfunded the plan in earlier years, a calculation most participants aren’t set up to make.

Employer Contributions Eat Into Your Limit

In a 401(k), an employer match sits on top of your own deferral limit. A 457(b) works the other way. The Section 457 annual limit applies to the total amount deferred under the plan, including any employer contributions.⁷ If your employer puts in $5,000, your own deferral space drops to $19,500. Participants who expect 401(k)-style stacking end up saving less than they planned.

Narrow Investment Menus and Higher Fees

Many 457(b) plans, especially at smaller tax-exempt employers, restrict participants to a short lineup of mutual funds or annuity contracts from a single vendor. A large corporate 401(k) platform typically offers dozens of low-cost index funds; an IRA opens up nearly everything. The 457(b) menu often does neither.

Smaller plans also lack the leverage large plans use to negotiate down expense ratios and administrative fees. Recordkeeping charges, custodial costs, and annuity contract fees quietly reduce returns. Over a 30-year career, a fee difference of 0.25% to 0.50% per year can cost tens of thousands of dollars in final balance. The plan’s fee disclosure document is worth reading before you enroll, though almost no one does.

Getting to Your Money Is Hard

In-service access to a 457(b) is tighter than what 401(k) participants are used to, and the differences matter when life gets expensive.

Withdrawals Require an Unforeseeable Emergency

A 401(k) permits hardship distributions for tuition, medical costs, or a first-home purchase. A 457(b) limits in-service withdrawals to an “unforeseeable emergency”: severe financial hardship from illness or accident affecting you, your spouse, or a dependent; uninsured casualty loss of property; or comparable extraordinary circumstances beyond your control, such as imminent foreclosure or eviction. Funeral expenses for a spouse or dependent qualify as well.⁸

College tuition and home purchases — routine hardship reasons for a 401(k) — do not count as unforeseeable emergencies for a 457(b).⁹ The withdrawal is also capped at the amount reasonably necessary to cover the emergency, and you must have exhausted other resources first.¹⁰

Loans Are Often Unavailable

Non-governmental 457(b) plans generally do not permit loans.¹ Governmental plans may allow them, depending on the plan document, and terms can be more restrictive than a 401(k)’s.

De Minimis Distributions

One narrow escape hatch: if your balance is $7,000 or less and neither you nor your employer has contributed for at least two years, you may take a one-time de minimis distribution. It’s available only once per employer, and the plan document must have adopted the provision. Useful for small forgotten accounts, not for genuine access to your savings.

Required Minimum Distributions

Like other tax-deferred accounts, a 457(b) requires distributions once you reach a certain age. Under SECURE 2.0, the RMD age is 73 for participants born between 1951 and 1959, and 75 for those born in 1960 or later. Missing an RMD triggers a 25% excise tax on the shortfall, dropping to 10% if you correct it within two years.¹¹¹²

For non-governmental participants, RMDs are often overshadowed by the more immediate distribution problem: many plans force payout shortly after separation and don’t allow funds to sit indefinitely. Governmental participants who are still working past RMD age can typically defer distributions until actual retirement, but non-governmental participants generally don’t have that flexibility.
