401(a) plans are employer-sponsored retirement accounts used mainly by public-sector and certain nonprofit employers. Employers control participation, contribution formulas, and tax treatment. Contributions usually grow tax-deferred; rollovers to IRAs or other plans are generally allowed. Always confirm current IRS limits, withdrawal penalties, and plan-specific rules with your plan administrator.

What a 401(a) plan is

A 401(a) is an employer-sponsored retirement plan commonly used by public employers, colleges, and some nonprofit organizations. Employers design the plan, set eligibility rules, and specify how contributions are made. Participation and contribution amounts can be mandatory or voluntary depending on your employer's plan document.

How contributions work

Employers can fund 401(a) plans in several ways: a fixed dollar amount, a fixed percentage of pay, or a variable formula. Employers may also require employee contributions. In some plans the employer "picks up" mandatory employee contributions, treating them as employer-paid for tax purposes.

Plan sponsors choose whether contributions are treated as pre-tax (tax-deferred) or after-tax. The tax treatment affects when you pay income tax on the money: pre-tax contributions are taxable on withdrawal; after-tax contributions may be nondeductible and treated differently.

Tax treatment and growth

Most 401(a) contributions grow tax-deferred: you don't pay federal income tax on earnings until distribution. The plan document and IRS rules determine what types of contributions are allowed and how distributions are taxed. Rollovers are commonly permitted to other qualified plans and IRAs, which helps consolidate savings when you change jobs.

Limits and rules

Federal tax law limits how much can go into qualified retirement plans each year. Those limits change periodically with cost-of-living adjustments, and some limits apply to total employer and employee contributions combined. Check your plan administrator and the IRS for current dollar limits. 1

Withdrawals and penalties

Distributions from a 401(a) are typically taxed as ordinary income. Early distributions (before age 59½ in many cases) may incur a 10% additional federal penalty unless an exception applies. The plan document and IRS rules govern exceptions and withholding. Always verify rules with your plan administrator and the IRS before withdrawing. 2

Why people use 401(a) plans

401(a) plans help employees build retirement savings through employer-driven contributions and tax-deferred growth. Payroll deduction makes saving automatic. When you leave the employer, most plans allow you to roll over the balance to a traditional IRA or another employer plan, preserving tax advantages.

Key steps for participants

  • Read your plan summary and adoption agreement. They spell out mandatory participation, contribution formulas, and distribution rules.
  • Check current IRS contribution and distribution limits before planning withdrawals or rollovers. 3
  • Talk with HR or a financial advisor about how the 401(a) fits with other retirement savings (403(b), 401(k), IRAs).
A 401(a) can be a straightforward way to build retirement savings when your employer sets up contributions and keeps the plan rules clear. Verify specifics with your plan administrator and the IRS before making decisions.
  1. Confirm whether 401(a) plans can accept designated Roth (after-tax) contributions under current IRS rules.
  2. Verify the current annual contribution/annual additions limits that apply to 401(a) plans for 2025.
  3. Confirm the precise rules and exceptions for the 10% additional tax on early distributions from 401(a) plans under current IRS guidance.
