How 457(b) plans work

The 457(b) question is partly about saving and partly about the employer type, access rules, rollover path, and tax treatment.

Short answer

A 457(b) is a deferred compensation plan with employer-type differences.

IRS 457(b) guidance separates governmental and tax-exempt deferred compensation plans. IRS 2026 limit guidance lists the employee deferral limit at $24,500 for 401(k), 403(b), governmental 457 plans, and the TSP.

What you actually came to find out

Plain answers first. Sources stay below for checking details.

What is it?

A deferred compensation plan often used by governments and some tax-exempt employers.

What does it mean for my money?

It can add another workplace savings bucket beside a pension, 403(b), or IRA.

What changes over time?

Withdrawal access and rollover rules depend on plan type and separation timing.

What belongs in the plan?

Employer type, contribution limit, account tax treatment, and later access.

The key fork is whether the plan is governmental or tax-exempt, because that can change rollovers, creditor risk, and retirement access.

Neutral landscape

The shape of the question

IRS 457(b) guidance is the main source because the plan category matters.

Source trail: IRS: IRC 457(b) Deferred Compensation Plans, IRS: 401(k) limit increases to $24,500 for 2026, IRA limit increases to $7,500

IRS annual contribution sources provide the current-year limit context.

Source trail: IRS: Retirement Topics: Contributions, IRS: Publication 590-B: Distributions from Individual Retirement Arrangements

The family layer matters because the same rule can feel different when it affects a spouse, adult child, home, health care, or dream budget.
