Does the TSP have anything like the 457(b) early-withdrawal advantage?

Partially. Separate from federal service in the year you turn 55 or later (50 for law enforcement, firefighters, and air traffic controllers) and TSP withdrawals are penalty-free. Separate at 52 as a regular employee and you face the 10% penalty unless you use a 72(t) plan or another narrow exception.

What happens to my TSP if I leave federal service for a state job?

The balance stays in the TSP and keeps growing at some of the lowest fees of any retirement plan in the country. You stop contributing, but you can leave it there indefinitely, roll it to an IRA, or roll it into the state 457(b) if that plan accepts rollovers. Leaving it in the TSP is usually the best default.

457(b) vs TSP: What Government Workers Miss in 2026

Q: What is the 2026 contribution limit for a 457(b) plan and the TSP?

Both plans have a 2026 elective deferral limit of $24,500, up $1,000 from 2025. Catch-up limits are also shared: $8,000 for ages 50 to 59 and 64 plus, and $11,250 for ages 60 to 63 under the SECURE 2.0 super catch-up. Agency matching does not count against your deferral limit.

Q: Can I contribute to both a 457(b) and the TSP at the same time?

Yes, if you have concurrent access to both, such as a federal position plus a qualifying state or local government job. The limits sit in different sections of the tax code and are fully independent. In 2026 a dual-employed worker can defer $24,500 to each plan, $49,000 total, before catch-ups.

Q: Does a governmental 457(b) really have no early withdrawal penalty?

Correct. Once you separate from the employer, governmental 457(b) distributions carry no 10% early withdrawal penalty at any age. Ordinary income tax still applies. The critical caveat: rolling the 457(b) into an IRA permanently destroys this advantage, because IRA rules then apply to that money.

Q: Are 457(b) fees higher than TSP fees?

Usually. TSP expense ratios have historically run under 0.10%. State and local 457(b) plans range from about 0.10% at well-run large plans to 1.5% or more at insurance-based vendors. A 1% fee gap on a $300,000 balance costs about $3,000 a year, so ask your administrator for the all-in cost, not just fund expense ratios.

The TSP and the governmental 457(b) are the two big deferred-compensation plans in government work, and almost nobody who touches both systems knows how they interact. The limits are separate, which means $49,000 of pre-tax savings room in 2026 if you hold both. The 457(b) has an early-withdrawal advantage the TSP can't match. And one common rollover move destroys that advantage permanently. Here is the 457b vs TSP comparison for people who change sectors, work both jobs, or married someone on the other side.

The limits stack. The TSP limit and the governmental 457(b) limit sit in different sections of the tax code. With access to both in 2026, you can defer $24,500 into each: $49,000 total, or up to $71,500 at ages 60 to 63 with super catch-ups.
The 457(b) has no 10% early withdrawal penalty after you separate, at any age. The TSP only waives the penalty if you separate in the year you turn 55 or later (50 for 6c public safety employees).
The rollover trap: moving 457(b) money into an IRA permanently kills the penalty-free access. That money becomes subject to IRA rules, including the pre-59½ penalty.
The TSP wins on fees, decisively. Expense ratios under 0.10% versus 0.25% to 1.5%+ at many 457(b) vendors. A 1% gap on $300,000 costs roughly $3,000 a year.
Leaving federal service? Keep the TSP balance where it is by default. Entering federal service with a 457(b)? Think twice before consolidating.

Two plans, two rulebooks, separate limits

The TSP is the federal plan, governed by the same tax-code section as private 401(k)s. The governmental 457(b) is what states, cities, counties, and school districts offer, and it lives under its own code section. That separation is the whole story.

Both share the same 2026 numbers, confirmed by the IRS:

Limit (2026)	Amount
Elective deferral (each plan)	$24,500
Catch-up, ages 50-59 and 64+	$8,000
Super catch-up, ages 60-63	$11,250
Max per plan at 60-63	$35,750
Combined, both plans, 60-63	$71,500

Because the limits are independent, contributing $24,500 to a 457(b) does not use up one dollar of TSP room, and vice versa. No other plan pairing works this way: a 401(k) and a 403(b) share a single limit.

The $49,000 scenario: who actually qualifies

The stacking opportunity requires genuine concurrent eligibility in two plans from two employers:

A federal employee who also holds a qualifying part-time state or local position where the employer offers a 457(b)
A dual-career household, one spouse federal and one state, each maxing their own plan
A mid-year career changer who contributes to the TSP through the federal payroll, then to the 457(b) at the new state job, in the same tax year

Not every state employer offers a 457(b), and eligibility rules are plan-specific, so confirm enrollment terms before counting on the second bucket. But where it applies, this is the largest tax-advantaged savings channel available to government workers, and no major outlet publishes it with current limits.

The 457(b) early-withdrawal advantage

After you separate from the employer, for any reason and at any age, governmental 457(b) distributions carry no 10% early withdrawal penalty. Ordinary income tax applies, nothing else.

The TSP's version is narrower. Separate from federal service in the year you turn 55 or later and withdrawals are penalty-free; law enforcement, firefighters, and air traffic controllers under 6c coverage get the same treatment at 50. Separate at 52 as a regular employee, though, and TSP withdrawals cost you the 10% penalty unless you commit to a 72(t) substantially-equal-payments plan or qualify for a narrow exception like disability.

So a state worker who leaves at 52 can bridge to 59½ from the 457(b) freely, while a federal employee in the identical position cannot do that from the TSP. For anyone eyeing retirement before 55, a funded 457(b) is the most flexible bridge account in government work.

One scope note: this applies to governmental 457(b) plans. The 457(b) plans at tax-exempt nonprofits follow different rules and do not carry the penalty-free advantage.

The rollover trap that undoes it

The advantage travels with the plan, not the money. Roll a 457(b) into an IRA and that money becomes IRA money: the 10% pre-59½ penalty now applies to it, and there is no way to restore the old treatment short of rolling it into another employer plan someday.

Advisors suggest IRA consolidation constantly because it is tidy. For a 457(b) holder who might retire early, tidy is expensive. The full rollover grid:

Move	Allowed?	What to watch
457(b) → TSP	Yes, pre-tax to traditional, if done as a direct rollover	Penalty-free early access is lost on that money
TSP → 457(b)	Yes, if the receiving plan accepts rollovers	Fees at the 457(b) may be far higher
457(b) → traditional IRA	Yes	Destroys penalty-free early access
Roth 457(b) → Roth IRA	Yes, Roth to Roth	Standard Roth rollover rules apply

Always move money as a direct, trustee-to-trustee transfer to avoid withholding.

Fees: the TSP's durable edge

TSP expense ratios have historically run between 0.042% and 0.069%, among the lowest of any employer plan in the country. Governmental 457(b) fees are all over the map: large, well-run state plans land around 0.10% to 0.25%, while insurance-based 457(b) products can charge 1% or more once recordkeeping is counted.

The FedTools math on a 1% gap: about $3,000 a year on a $300,000 balance, and roughly $130,000 to $170,000 of lost growth over 20 years at 6% returns. That is why the default advice for departing feds is to leave the TSP balance in the TSP, and why every 457(b) participant should ask the administrator for the all-in cost, not just the fund expense ratios.

Career-change decision tree

Leaving federal for state. Your TSP stops taking contributions but stays invested at TSP fees. Start the 457(b) at the new employer; its penalty-free feature will cover your future separation. Default: do not consolidate. If a RIF forced the move, the TSP after a federal layoff guide covers the immediate decisions.

Leaving state for federal. You now get the FERS match: 1% automatic plus up to 4% matching, which the 457(b) world rarely offers. Contribute to the TSP first. Leave the old 457(b) balance where it is if early retirement is even a possibility; rolling it into the TSP trades away penalty-free access for fee savings, and the access is usually worth more.

Holding both. Fund the TSP at least to the full 5% match before anything else, since the match is an instant 100% return. Then split additional savings by your priorities: the 457(b) for early-access flexibility, the TSP for fees.

High earners, one more 2026 wrinkle: if your prior-year wages topped roughly $145,000, age-50+ catch-up contributions must now be designated Roth. The TSP has a Roth option, so federal employees are fine. If your 457(b) plan never adopted Roth, you may be locked out of catch-ups there entirely. Weighing Roth moves inside the TSP?

Frequently Asked Questions

What is the 2026 contribution limit for a 457(b) plan and the TSP?

Both are $24,500 for 2026, up $1,000 from 2025. Catch-ups are shared too: $8,000 at ages 50 to 59 and 64 plus, $11,250 at 60 to 63. Agency matching does not count against your limit.

Can I contribute to both a 457(b) and the TSP at the same time?

Yes, with concurrent access to both plans through two employers. The limits are independent, so 2026 allows $24,500 into each: $49,000 combined before catch-ups.

Does a governmental 457(b) really have no early withdrawal penalty?

Correct. After separation, distributions at any age skip the 10% penalty; only ordinary income tax applies. Rolling the money into an IRA permanently forfeits this.

Does the TSP have anything like that?

Partially. Separating in the year you turn 55 or later (50 for 6c public safety) makes TSP withdrawals penalty-free. Below that, you need a 72(t) plan or a narrow exception.

What happens to my TSP when I leave federal service?

It stays put and keeps growing at TSP fees. You can leave it indefinitely, roll to an IRA, or roll to a 457(b) that accepts transfers. Leaving it is usually right.

Are 457(b) fees higher than TSP fees?

Usually. TSP runs under 0.10%; many 457(b) plans charge 0.25% to 1.5% or more all-in. Audit yours: a 1% gap on $300,000 is about $3,000 a year.
