What is a 401(a) plan?

A 401(a) is an employer-sponsored retirement plan common in government, education and nonprofit organisations. Unlike a 401(k), participation and contribution amounts are often mandatory — set by the employer rather than elected by the employee.

Section 01

How a 401(a) works

The employer defines who participates, how much is contributed and the vesting schedule. Contributions can be a fixed dollar amount, a percentage of salary or a match, and employee contributions may be pre-tax or after-tax depending on plan design.

Section 02

401(a) vs 401(k)

401(a): employer sets contributions, often mandatory, common in public sector

401(k): employee elects contributions, common in private sector

Both grow tax-deferred and are subject to required minimum distributions

Both can usually be rolled into an IRA after you leave the employer

Section 03

FAQ

What is the 401(a) contribution limit?

Total employer and employee additions to a 401(a) are capped by the IRS annual additions limit, which is indexed each year and separate from the 401(k) elective deferral limit.

Can you roll a 401(a) into an IRA?

Key takeaway

Yes. After leaving the employer, a 401(a) can usually be rolled into a traditional IRA or another employer plan.

Are 401(a) contributions taxed?

Employer contributions and pre-tax employee contributions are not taxed until withdrawal. After-tax contributions are taxed now, and only the growth is taxed later.

What is the difference between a 401(a) and a 401(k)?

A 401(a) is designed by the employer, which sets eligibility and contribution levels, often mandatorily. A 401(k) is driven by employee elective deferrals.

What the retirement calculator can estimate

A retirement savings calculator projects how current savings and future contributions might grow under a chosen return assumption. It can also estimate a potential retirement balance or test how long a balance may support planned withdrawals. Because actual investment returns vary, compare several scenarios instead of treating one result as certain. Include workplace accounts such as a 401k, individual accounts, taxable investments, and any pension benefits that apply.

Effective retirement planning also considers inflation, taxes, health expenses, debt, and the timing of Social Security or pension income. Full retirement age is a Social Security term and is not necessarily the age when someone must stop working. An annuity may create a contractual income stream, but fees, guarantees, liquidity restrictions, and insurer claims-paying ability depend on the specific product. Review assumptions regularly as income and expenses change.
