The Differences Between 403(b), 457(b), and 401(k) Plans

Choosing the right retirement vehicle can feel like navigating a maze. This guide breaks down the differences between 403(b), 457(b), and 401(k) plans in a friendly, practical way. We’ll cover who gets them, contribution limits (with accurate 2024 figures), withdrawal rules, tax options, and strategies so you can make smart choices for your situation.

Quick overview: what each plan is and who it’s for

At a glance:

• 401(k) — Common in private-sector companies. Employers often match contributions. Offers pre-tax and frequently Roth options.
• 403(b) — Mainly for employees of public schools, colleges, and certain non-profit organizations. Similar to a 401(k) but with a few special rules, especially for long-time employees.
• 457(b) — Typically offered to state and local government employees and some non-profit executives. Has unique withdrawal rules and catch-up potential.

“Understanding the shape of the plan — who offers it and what restrictions apply — is half the battle. The other half is how it fits into your overall retirement road map,” said a retirement planner who works with public- and private-sector clients.

2024 contribution limits and key numeric differences

The IRS sets annual contribution limits that apply across these types of plans. Below are the 2024 figures most savers should know:

Note: IRS rules change occasionally. These figures reflect 2024 amounts. If you’re planning contribution strategies, confirm current limits with your plan administrator or tax advisor.

Tax treatment and Roth options

All three plan types primarily offer pre-tax (traditional) contributions, which reduce taxable income today and are taxed when you take withdrawals in retirement. Many employers now also offer Roth options, which let you pay taxes up front and take qualified withdrawals tax-free later.

• 401(k): Commonly offers both traditional and Roth options.
• 403(b): Increasingly offers Roth features, but availability varies by employer.
• 457(b): Roth versions exist for some governmental plans; availability depends on plan rules.

“If you expect to be in a higher tax bracket later, putting money into Roth contributions can be a wise bet. If you need the tax break now, pre-tax contributions make sense,” says a tax-savvy financial advisor.

Early withdrawal rules and penalties

Knowing when you can access money without penalties matters — especially if you change jobs, retire early, or face a big life event.

• 401(k) and 403(b): Withdrawals before age 59½ are typically subject to a 10% early distribution penalty plus income tax, unless you meet an exception (hardship, substantially equal periodic payments, separation from service after age 55 for 401(k), disability, etc.).
• 457(b) (governmental): Unique advantage — distributions after separation from service are not subject to the 10% early withdrawal penalty, even if taken before age 59½. Income tax still applies. (Non-governmental 457(b) plans may have different rules.)

Loans, hardship withdrawals, and portability

Accessing your retirement money before retirement isn’t generally recommended, but plans can permit it in structured ways:

• Loans: Many 401(k) and 403(b) plans allow loans (typical limit: the lesser of $50,000 or 50% of the vested account balance). 457(b) plans may allow loans depending on the plan.
• Hardship withdrawals: Available in 401(k) and some 403(b) plans under strict conditions. These are taxable and may include the 10% penalty if no exception applies.
• Portability: You can usually roll over 401(k) funds into another 401(k) or an IRA. 403(b) plans can also roll into IRAs or other employer plans, though some 403(b) investments (like annuities) have special rules. Governmental 457(b) funds can often be rolled into other governmental 457 plans, IRAs, or qualified employer plans.

Employer match and vesting

Employer contributions are common in 401(k) plans and sometimes in 403(b) plans; 457(b) plans less frequently have employer matches, though it’s not unheard of.

• Employer match formulas vary — a typical private employer match might be 50% of the first 6% of salary, meaning a 3% match on a 6% employee contribution.
• Vesting schedules define when employer contributions actually belong to you. Vesting can be immediate or spread over several years (e.g., 3-to-6-year graded schedules).

Special 403(b) rules: the 15-year service catch-up

403(b) plans offer a distinctive extra catch-up for long-serving employees at eligible employers (typically public schools and certain non-profits).

• If you have 15 or more years of service with certain employers, you may be able to contribute an additional up to $3,000 per year above the standard limit, with a lifetime cap of $15,000. This is subject to plan rules and eligibility tests.
• This is especially useful for educators who start saving later in their careers and need to accelerate contributions before retirement.

Why a 457(b) can be a powerful complement to a 401(k) or 403(b)

One of the most attractive features of 457(b) government plans: the contribution limit for a 457(b) is separate from your 401(k) or 403(b) limit. That can let you save significantly more in tax-advantaged accounts if your employer offers both.

Combining plans — practical strategies

Which order should you fund first? Here are some practical rules of thumb, but remember your personal tax picture and employer match change the math:

• If your employer offers a match, contribute enough to get the full match first — it’s essentially free money.
• If you have a 457(b) and you want flexibility in early retirement, consider funding the 457(b) because it allows penalty-free withdrawals after separation from service (governmental plan).
• If you expect higher taxes later, prioritize Roth contributions (within your plan’s Roth option) for tax-free growth and withdrawals in retirement.
• High earners aiming to maximize tax-deferred savings can use both a 401(k)/403(b) and a 457(b) to compound retirement savings quickly.

RMDs and later-life planning

Required Minimum Distributions (RMDs) generally apply to these plans when you reach the required age (currently 73 for many taxpayers, subject to legislative changes). Roth 401(k) or Roth 403(b) accounts are subject to RMD rules, though Roth IRAs are not — so many people roll Roth employer accounts into a Roth IRA to avoid RMDs.

Which plan should you choose? Typical scenarios

Here are several common situations and the recommended mindset for each.

Scenario 1 — Private-sector employee with employer match

• Prioritize the employer match in your 401(k) — contribute at least enough to get the full match.
• Consider Roth if you’re younger and expect to be in a higher tax bracket later.

Scenario 2 — Teacher or non-profit employee with a 403(b)

• Take advantage of any employer match first.
• If you’re a long-time employee (15+ years), check the 403(b) special catch-up — it can meaningfully increase your contribution room.

Scenario 3 — Government employee with a 457(b)

• Consider maxing the 457(b) if you might retire early — the penalty-free withdrawal after separation gives you extra flexibility.
• If you also have a 401(k) or 403(b) from another job, contribute to both up to their limits for accelerated saving.

Real-world numbers: a three-person example

To make the comparisons concrete, here are three realistic examples showing how contributions and employer matches add up in 2024.

Common questions people ask

Can I contribute to both a 401(k) and a 403(b)?

You generally won’t have both at the same employer, but you can participate in a 401(k) and a 403(b) if they come from different employers. Each plan’s elective deferral limit applies separately only to 457(b) — 401(k) and 403(b) limits are the same $23,000 cap for 2024 across those respective plans.

Can I roll over between these plans?

Yes, rollovers are common:

• 401(k) to IRA or other employer plan (if accepted).
• 403(b) to an IRA or another qualified employer plan, depending on investment type and plan rules.
• 457(b) to an IRA or certain employer plans; governmental 457(b) rollovers have their own set of allowable destinations.

Is a 403(b) better than a 401(k)?

Neither is universally better — it depends on plan features. 403(b) plans sometimes offer annuity investment options and the 15-year catch-up; 401(k)s often have broader investment menus and more employer matching. Compare fees, investment choices, and matching formula to decide.

Final checklist when choosing or reviewing a plan

• Confirm current IRS limits for the year you’re contributing.
• Find out if your plan offers a Roth option and compare tax implications.
• Ask whether your plan allows loans or hardship withdrawals and what the fees/penalties are.
• Check vesting schedule on employer contributions.
• Verify whether your plan is governmental (for 457 rules) or non-governmental.
• Compare plan fees and investment choices — low-cost index funds often outperform high-fee actively managed options.

Closing thoughts

Each plan has strengths. 401(k)s are the most common in private industry and frequently offer matching; 403(b)s are tailored to educators and non-profits and have special long-service opportunities; governmental 457(b)s give a valuable early-withdrawal flexibility that can be life-changing for those who might retire before 59½. Combining plans, when possible, is a powerful way to boost retirement savings.

“No one plan is a silver bullet. The best approach is to match the plan features to your goals — whether that’s maxing tax-advantaged contributions, achieving flexibility for an early retirement, or minimizing taxes in retirement,” a retirement strategist advises.

If you’re uncertain about which move makes sense for you, consider speaking with a certified financial planner or tax advisor who can model the impact on your specific finances. Small choices today — a Roth vs. pre-tax contribution, or prioritizing a 457(b) vs. a 401(k) — can add up to tens or hundreds of thousands of dollars over a career.
