401(k) vs. 403(b) vs. 457(b) Plans
A 401(k) is a qualified employer plan commonly used in private employment; a 403(b) serves public schools and certain tax-exempt organizations; and an eligible 457(b) is deferred compensation sponsored by state or local governments or eligible tax-exempt employers.
- Their tax timing can look similar, but sponsor eligibility, annuity options, deferral limits, and distribution rules differ.

These three labels identify employer-sponsored retirement arrangements, not three competing insurance policies. They often let workers defer part of pay and tax, but their legal homes are different. A 401(k) is a qualified plan feature familiar in private employment. A 403(b) is offered by public schools and certain tax-exempt organizations and has a long connection to annuity contracts. An eligible 457(b) is deferred compensation for eligible government or tax-exempt employers, with important differences between governmental and nongovernmental plans. For a Life Agent exam question, identify the sponsor first, then the contribution and distribution rule, then any annuity held under the arrangement.

Start with the employer, not the investment brochure
A worker usually encounters these arrangements through an employer. The employer's legal status determines which plan it may establish, subject to the governing rules. A for-profit company's retirement program commonly includes a 401(k). A public school system may offer a 403(b), a governmental 457(b), or both. A qualifying charity may offer a 403(b) and may have a nongovernmental 457(b) for eligible employees. The same salesperson could show an annuity product in more than one setting, but the annuity's presence does not change the employer plan's statutory label.
This is the first exam shortcut worth keeping. If the question names a public-school teacher and a tax-sheltered annuity, think 403(b). If it names a state employee in a deferred-compensation program, think governmental 457(b). If it names a private company with salary deferrals into a qualified account, think 401(k). Still read the remaining facts: some employees can have more than one plan, and the label alone does not reveal whether their contribution is traditional or designated Roth, what investments are available, or when they may receive a distribution.
How a 401(k) works
The IRS describes a 401(k) as a qualified plan that lets an eligible employee elect to have some wages contributed by the employer to an individual account under the plan. Traditional elective deferrals generally are not included in federal taxable income when deferred. The employer may also contribute under the plan's rules. The account later follows its distribution and tax rules. A 401(k) can offer a designated Roth feature, but that feature must be offered by the plan; it is not a separate Roth IRA. The worker's pay, employer match, vesting, and investment choices are distinct issues.
An exam item may ask whether an employer's matching contribution is the same as the employee's salary deferral. It is not. The employee elects to defer wages, while the employer may add a match or another contribution under the plan. The tax and vesting treatment of employer amounts can differ from the worker's elected Roth or traditional deferral. Another question may mention a loan, hardship withdrawal, or rollover. Those are plan and federal-rule matters, not automatic rights created by the words 401(k). Read the plan conditions and current IRS rules before assuming they are available.
How a 403(b) works
A 403(b) is also called a tax-sheltered annuity plan or TSA, but that name does not mean every 403(b) account must be an insurance annuity. The IRS says eligible employers include public schools and certain tax-exempt organizations. Plan funding can involve an annuity contract issued by an insurer, a custodial account generally invested in mutual funds, or a retirement income account for certain church employees. Employees can make salary-reduction contributions; employers may contribute as well. The plan document controls the options an individual worker actually has.
The 403(b) label matters for the Life Agent exam because it connects an insurance annuity to an employer retirement plan. Do not merge the plan with the contract. The 403(b) defines eligibility, contribution, and tax rules. The annuity contract, when used, defines charges, guarantees, payout choices, and beneficiary terms. A custodial 403(b) holding mutual funds has no insurance guarantee merely because someone calls the overall arrangement a tax-sheltered annuity plan. Distinguishing wrapper from asset prevents several attractive but wrong answer choices.
How a 457(b) works
Section 457(b) covers eligible deferred-compensation plans established by state or local governments and certain tax-exempt employers. Participants defer compensation that would otherwise be paid currently, within the applicable annual limit and plan terms. Governmental and nongovernmental 457(b) plans are not interchangeable. Governmental plans have trust, custodial, or qualifying annuity protections for participants under federal rules. A nongovernmental tax-exempt employer plan can have different funding and creditor-risk treatment. If a question specifies one version, use its facts rather than a generic '457' rule.
A governmental 457(b) can be especially relevant to a public employee who also has access to another employer plan. The IRS states that eligible 457(b) deferrals generally have a separate limit rather than being combined with 401(k) and 403(b) elective deferrals. That does not mean a worker can contribute any amount without restriction. Compensation, plan limits, annual federal limits, and catch-up rules still apply. The useful exam distinction is separate limit versus shared 401(k)/403(b) limit, not a memorized dollar figure that may change next year.
Traditional and designated Roth contributions are choices within plans
A traditional elective deferral generally reduces current federal taxable wages and is taxable when distributed. A designated Roth elective deferral is included in current taxable income; a later qualified distribution may be excluded from income under its conditions. A 401(k), 403(b), or governmental 457(b) may offer the designated Roth choice if the plan allows it. The word Roth therefore does not prove the worker owns a Roth IRA. A designated Roth account sits within the employer plan and follows plan-specific contribution, distribution, and rollover rules.
Suppose two teachers work for the same district's 403(b). One chooses traditional salary deferrals, the other designated Roth deferrals. Both are in a 403(b), but their current federal tax treatment differs. Suppose a private employee chooses a designated Roth 401(k) contribution. It is taxed currently like a Roth contribution, but the account remains in a 401(k) plan. For the Life Agent exam, identify both dimensions: plan type and tax designation. For a real recommendation, current and future tax circumstances, plan availability, and investment costs also matter.
Understand the contribution-limit relationship
The IRS instructs workers participating in more than one retirement plan to combine 401(k) and 403(b) elective deferrals for the general individual deferral limit, subject to detailed exceptions and plan-specific rules. A person cannot ordinarily treat each 401(k) and 403(b) as a full separate employee-deferral allowance. Eligible 457(b) deferrals generally have a separate limit. Employer contributions and annual-additions limits involve different calculations. This is a structure to learn, not a reason to assume everyone has two plans or can maximize both.
Use an example without fixed current-year dollars. A worker eligible for both a 401(k) and 403(b) contributes to one, then attempts to contribute the full individual elective limit again to the other. The second contribution may exceed the combined limit. If that worker also has a governmental 457(b), its eligible deferrals are examined under a separate 457(b) limit. The worker still needs enough compensation and plan permission. Exact annual amounts and catch-up provisions change, so consult the current IRS table when an actual payroll election is made.
403(b) catch-up rules add detail
A 403(b) plan may permit a special catch-up for an employee with sufficient years of service with certain eligible employers, in addition to age-based catch-up rules when applicable. The IRS Publication 571 explains conditions, sequencing, and limits. This is one reason a generic table that makes 401(k) and 403(b) limits look identical can mislead. The employer must offer the provision, the employee must qualify, and the available amount is not simply any number chosen by the employee. If the exam supplies qualifying years and a stated limit, follow the stated facts.
A governmental 457(b) has its own catch-up possibilities, including a special catch-up near the plan's normal retirement age and, if offered, an age-based option. The IRS explains that when both types are available under the same governmental 457(b), a participant uses the option allowing the larger deferral rather than stacking both. Do not import the 403(b) years-of-service rule into a 457(b) plan or vice versa. The general exam-level skill is to recognize that each section has plan-specific catch-up conditions.
Early distributions are a major distinction
A distribution from a 401(k) or 403(b) before age 59½ can be subject to the 10% additional tax on early distributions unless an exception applies, in addition to ordinary income tax where applicable. A governmental 457(b) distribution generally is not subject to that particular 10% additional tax on amounts attributable to the plan's own eligible deferrals. This does not make the withdrawal tax-free, and it does not mean a participant can take money at any time contrary to plan and federal distribution rules.
The IRS notes an important caveat: amounts rolled into a governmental 457(b) from certain other retirement plans or IRAs may remain subject to early-distribution treatment. If a question mixes rollover funds with the plan's own deferred compensation, keep those sources distinct. A nongovernmental 457(b) also has different characteristics and should not be granted every governmental-plan feature. A good answer names the plan type, source of funds, event permitting distribution, income-tax treatment, and possible additional tax. One-word rules about 'early withdrawal penalties' are too imprecise.
A 403(b) annuity is still a contract
When a 403(b) uses an annuity contract, the insurer's contract may describe fixed crediting, variable investment options, annuitization, death benefits, riders, surrender charges, and fees. The federal tax benefit comes from the employer plan's rules, not from a promise that the annuity itself has no costs or risk. A variable annuity's account value can move with investments, while insurer guarantees depend on contract terms and claims-paying ability. A life agent should explain both the retirement-plan wrapper and the product's costs and benefits.
Conversely, a 403(b) custodial mutual-fund account is not an annuity contract merely because the plan category retains the historical TSA name. This distinction is particularly useful in exam questions that ask which institution provides a guarantee, who bears investment risk, or what happens at surrender. Identify whether the underlying asset is an insurance contract or a custodial investment before making a claim about surrender charges or guarantees. The employer's 403(b) sponsorship does not resolve those product questions on its own.
Rollover and portability questions require a destination
A worker who leaves an employer may have choices under the plan and federal law: keep eligible funds in the old plan, roll them to another eligible plan or IRA, or take a distribution. Each choice can have tax, fee, investment, and creditor-protection consequences. A direct rollover and an indirect 60-day rollover are not identical procedures. Nor is moving pre-tax money to a traditional IRA the same tax event as converting it to a Roth IRA. The plan's 401(k), 403(b), or 457(b) label is the starting point, not the entire rollover answer.
For an exam scenario, ask what the source plan is, whether it is governmental or nongovernmental if 457(b), whether money is traditional or designated Roth, and what the destination accepts. Then ask if the question is about immediate tax, withholding, later distribution, or continued deferral. In particular, moving governmental 457(b) funds to a different plan can change the treatment of a later early distribution. Tax law and plan documents can change; use the current IRS guidance for a real rollover decision rather than relying only on a general article.
Do not confuse any of these plans with an IRA
A traditional IRA or Roth IRA is an individual retirement arrangement, while these are employer-sponsored plans or deferred-compensation arrangements. An individual may own an IRA and participate in a workplace plan at the same time, but contribution, deduction, and distribution rules are not interchangeable. For example, a Roth IRA does not have the same sponsor or payroll-deferral mechanism as a designated Roth account in a 401(k). A 403(b) annuity under an employer plan is not automatically an IRA annuity. Use the exact account label in each question.
This also explains why the word 'qualified' can cause trouble. A 401(k) exists within a qualified plan; a 403(b) is governed by its own section of the Code; a governmental 457(b) is eligible deferred compensation. A nonqualified annuity outside any employer plan may be purchased with after-tax funds and has its own taxation. Using 'qualified' casually to mean 'tax-favored' can blur these legal categories. In an exam response, name the plan or account and its specific rule instead of leaning on a broad label.
A compact exam method
Read the employer first. Private business suggests a 401(k) context; public school or eligible charity suggests 403(b); state or local government deferred compensation suggests governmental 457(b). Next identify the worker's contribution type: traditional pretax or designated Roth if available. Then isolate the question being asked: contribution limit, annuity funding, early distribution, rollover, employer match, or tax treatment. Finally check whether the stem supplies an exception or a second plan. This sequence turns a long retirement question into a small number of decisions.
Remember the durable distinctions rather than a year's dollar figures. A 401(k) is a qualified salary-deferral feature; a 403(b) is for specified school and tax-exempt employers and can use insurer annuities; a 457(b) is eligible deferred compensation, with governmental and nongovernmental versions. Traditional deferrals can postpone income tax, designated Roth deferrals use current after-tax income, and qualified Roth distributions may receive exclusion. 401(k) and 403(b) elective deferrals generally share a limit, while 457(b) has a separate one. Governmental 457(b) early distributions have a distinctive additional-tax rule with caveats.
How to study this for the Texas Life Agent exam
The Pearson Life Agent outline includes retirement-plan concepts within its broader life and annuity section. Build a one-page comparison from the current IRS source and practice three fact patterns: a private employee with a 401(k), a teacher with a 403(b) annuity, and a municipal employee with a governmental 457(b). For each, state who sponsors the plan, whether an annuity contract is necessarily involved, how a traditional deferral is taxed, and what happens if money is taken early. Then add a second plan or a designated Roth choice and explain what changed.
Keep tax-year limits and distribution ages separate from the stable structure because federal thresholds and rules can change. If a practice item gives a specific current-year limit, verify it with the IRS rather than a generic chart. If it asks only which employer may offer which arrangement, do not waste time calculating contributions. A life agent may discuss products within these plans, but a sale or recommendation also requires attention to product suitability, compensation, fees, and the client's actual plan options. An exam explainer organizes the distinctions; it does not determine a person's tax outcome.
Common questions
Is a 403(b) always an annuity?
No. Although a 403(b) is often called a tax-sheltered annuity plan, IRS guidance says it can use an insurance annuity contract, a custodial account generally invested in mutual funds, or a qualifying church retirement income account. The plan label does not prove that the worker owns an insurer contract.
Can someone contribute to both a 403(b) and 457(b)?
A person may be eligible for both if the employer offers them and the individual qualifies. The IRS says eligible 457(b) deferrals generally have a separate limit from 403(b) and 401(k) elective deferrals. Plan terms, compensation, current-year limits, and catch-up rules still govern the actual amounts.
Does a governmental 457(b) withdrawal avoid income tax?
No. A traditional governmental 457(b) distribution can be taxable as income. Its special distinction is that the 10% additional early-distribution tax generally does not apply to its own eligible deferrals, subject to important exceptions for certain rollover amounts and the applicable distribution rules.
Is a designated Roth 401(k) account a Roth IRA?
No. A designated Roth account is a feature inside an employer plan such as a 401(k), 403(b), or governmental 457(b). It shares after-tax contribution and qualified-distribution ideas with a Roth IRA, but sponsorship, contribution limits, rollover choices, and plan rules differ.
