403(b) vs 457(b): An Overview

Both 403(b) and 457(b) are employer-sponsored retirement savings plans offered to eligible public sector employees and nonprofit organization staff.

These supplemental retirement plans provide options for contributing pre-tax and, in some cases, after-tax income for retirement savings.

Eligible employees and their respective employers can contribute up to the annual limits set by the Internal Revenue Service (IRS).

The amount available upon retirement is determined by the contributions made plus accumulated earnings minus taxes (if pre-tax dollars funded the account).

Generally, these retirement plans work similarly.

However, there are significant contrasts regarding employer contributions, catch-up contributions, and withdrawal penalties.

What Is a 403(b) Plan?

A 403(b) is a retirement plan sometimes offered to certain employees of public schools, hospital services organizations, and nonprofit or tax-exempt entities under Section 501(c)(3) of the Internal Revenue Code (IRC).

Sometimes called a Tax-Sheltered Annuity (TSA) plan or Tax-Deferred Annuity (TDA) plan, the 403(b) could only be used to invest in annuity contracts when it was first established.

However, most plans now offer mutual funds as an additional investment choice.

How 403(b) Plans Work

Like the 401(k) plan, participants can save for retirement in a 403(b) through payroll deductions while benefiting from certain tax advantages.

Employers also have the option of matching a portion of employee contributions.

The 403(b) plan can allow participants to make pre-tax or post-tax contributions.

With pre-tax contributions, taxes on contributions and earnings are deferred until withdrawal.

On the other hand, with post-tax contributions to a Roth 403 (b) account, taxes are paid before funding the account, so qualified distributions are tax-free.

Generally, 403(b) plan owners select annuity contracts and mutual funds that offer tax-deferred growth.

403(b) plans have loan provisions similar to the 401(k) plans.

The amount that can be loaned is $50,000 maximum or half the balance of the plan, whichever is lower. If a loan is not repaid within five years, it is considered a taxable distribution.

Furthermore, both types of plans allow employees to withdraw before retirement if they meet certain conditions, such as needing to take a hardship distribution.

Advantages and Disadvantages of a 403(b) Plan

Below are some of the advantages of a 403(b) retirement plan:

  • Convenient Set-up: 403(b) contributions can be arranged through payroll deduction. This makes saving for retirement more straightforward and more convenient.
  • Tax-Deferred Savings: With a 403(b) plan, most deposits are made on a pre-tax basis, which means they are deducted from the salary before taxes are taken out. This lowers the annual taxable income and can result in significant tax savings.
  • Higher Contribution Limits: The contribution limit for 403(b) is higher than for other retirement plans like individual retirement arrangements (IRAs).

However, it also has some disadvantages:

  • Early Withdrawal Penalties: If withdrawal from a 403(b) account is made before age 59½, a 10% early withdrawal penalty and regular income taxes on the amount withdrawn will be applicable.
  • Limited Investment Options: One of the most significant drawbacks of 403(b) plans is that they typically offer limited investment options. In this case, an individual may have little control over how their money is invested.
  • Higher Fees: Another downside of 403(b) plans is that they often come with higher fees than other retirement plans. For example, record-keeping and administrative fees can range from 0.0008% to 2.01% of the assets held in the plan.

What Is a 457(b) Plan?

A 457(b) is a retirement savings plan offered to local and state government employees and employees of nonprofit or tax-exempt entities.

Like the 403(b) plan, owners of a 457(b) plan may invest in either annuities or mutual funds.

How 457(b) Plans Work

Like a 403(b), a 457(b) plan can be funded with employees' pre-tax or post-tax contributions. Employer contributions are optional, and many choose not to make any.

Pre-tax contribution means funds are deducted from an employee's paycheck before taxes are withheld.

This reduces the employee's annual taxable income, which can result in significant tax savings. However, taxes need to be paid once withdrawals are made later on.

With post-tax contributions, withdrawal of contributions from the account is tax-free. However, taxes need to be paid upon the withdrawal of any earnings.

Withdrawals from a 457(b) account are difficult if an individual is still employed by the company sponsoring the plan.

However, when no longer connected with the company, individuals may make fund withdrawals without being subjected to the 10% early withdrawal penalty.

Advantages and Disadvantages of a 457(b) Plan

Below are some of the advantages of a 457(b) retirement plan:

  • Tax-Deferred Savings: The money in 457(b) accounts grows tax-deferred until withdrawal is made. No taxes are deducted from any investment gains until withdrawal is made from the account.
  • Special Catch-up Contributions: Participants within three years of regular retirement age can double their retirement plan contributions.
  • Option to Rollover to a Roth IRA or 401(k): If an individual leaves their job, they have the option of rolling over their account into a Roth IRA or 401(k) for a 457(b) plan.
  • No Early Withdrawal Penalty: There are zero penalties for taking funds out of a 457(b) account before age 59½. However, regular income taxes are to be paid.

However, it also has some disadvantages:

  • Possibility of Forfeiture: The vesting period for 457(b) plans is two years. If an employee leaves his job before the two-year period is complete, the funds in the plan may be forfeited.
  • Few Employers Offer Matches: Under a 457(b) plan, few employers offer matching contributions. This means participants may not receive an employer match which gives them a disadvantage compared to individuals who possess a 401(k).
  • Maximum Contribution Limit Includes Employer Contribution: Employer contributions are subject to the same limit as employee contributions, meaning employees cannot benefit much from employer matching policies.
  • Limited Investment Options: 457(b) plans are only invested in annuities and mutual funds, giving participants limited options compared to other retirement plans.

Differences Between a 403(b) Plan and a 457(b) Plan

Both plans have some similarities, but they also share vital differences.


Employees engaging in the daily operations of public schools, especially those managed by Indian tribal governments, have 403(b) contribution rights given to them by the IRS.

Employees of hospital service organizations and the staff of nonprofit or tax-exempt 501(c)(3) organizations are also eligible for a 403(b) plan.

Meanwhile, the 457(b) is offered to local and state government employees and some nonprofit or tax-exempt organizations staff.

Employee Contribution Limits

In 2024, the maximum contribution for both a 403(b) plan and a 457(b) plan is $23,000.

This is an increase from the 2023 employee contribution limit of $22,500.

Low and mid-income contributors may also be eligible for a Retirement Savings Contribution Credit, also known as Saver’s Credit.

This maximum tax credit is up to $1,000 for individuals and $2,000 for jointly-filing married couples contributing to a retirement account.

Employer Contribution Limits

The employer contribution limit for the 457(b) plan is combined with the limit for employee contributions. In 2024, this limit is $23,000, which is an increase from 2023's $22,500 limit.

In contrast, 403(b) enables total contributions of up to $69,000 in 2024 (increased from $66,000 in 2023).

This means employers still have much leeway to add their contributions when combined with the employee contribution limit.

The IRS has a specific order for calculating an individual's total 403(b) contributions since many sources must be accounted for.

First, they apply the elective deferral. Then they consider the 15-year service catch-up provision and, finally, the catch-up contribution for those aged 50 and above.

It is an employer's responsibility to ensure that employees contribute only what is allowed.

Catch-up Contributions

Contributors who are at least 50 years old can also take advantage of an additional “catch-up” contribution of $7,500 per year for both the 403(b) and the 457(b) plans.

In addition, each plan type also has its own additional special catch-up contribution provisions.

The 403(b) has a lifetime catch-up provision which is an additional benefit for those who have been with their company for at least 15 years.

It allows employees to make an extra $3,000 contribution each year for the next five years, which is a total of $15,000.

Individuals with a 457(b) who have not previously contributed the maximum amount can contribute up to $46,000 (up from $45,000 in 2023) if they are within three years of regular retirement age.

Early Withdrawal Penalties

Employees can start collecting their benefits from the 457(b) plan without any withdrawal penalties once they leave their job.

If not, distributions are allowed when the employee reaches 73 years old (or 70½ if they turned that age before 2020).

This is different from the withdrawal rules of a 403(b) plan.

Withdrawal of funds is already permitted starting at age 59½. A 10% federal penalty tax and income taxes will be collected if fund withdrawal is made before that age.

Required Minimum Distribution (RMD) is the amount of money that must be withdrawn from a tax-deferred employer-sponsored retirement plan if individuals want to avoid the 25% excise tax.

RMDs begin at age 73 for both the 403(b) and the 457(b) plans.

Some investors may be able to circumvent RMDs if they roll their plan into a Roth IRA or other Roth retirement plan.

Investment Options

Both 403(b) and 457(b) plans generally have fewer options than 401(k) plans. Investment choices are limited to annuities and mutual funds.

Choosing0Between 403(b) And 457(b) Plans

When choosing between a 403(b) plan or a 457(b) plan, individuals can consider the following factors:

  • Extra Savings: A 457(b) plan is the best option if you want to save up more retirement funds in a shorter period of time. It has a special catch-up policy of up to $44,000 in 2024. This is higher than the additional $15,000 within five years of the 403(b) plan.
  • Contribution Limits: The 403(b) plan has a higher combined employer and employee contribution limit of $69,000 in 2024 compared to the $23,000 limit of a 457(b). If your company offers matching contributions, they have more room to contribute in a 403(b).
  • Liquidity: The funds in a 457(b) plan are more accessible than those in a 403(b). Once you leave your company, you can withdraw funds from a 457(b) plan without incurring penalty fees. This is a good option if you need to access it for emergencies.

Overall, both 403(b) plans and 457(b) plans can be excellent options for employees saving for retirement.

However, the specific features of each type of plan should be taken into account when making a decision about which one is right for you.

The Bottom Line

The 403(b) and the 457(b) are employer-sponsored retirement savings plans offered to eligible public sector employees and nonprofit organization staff.

These plans have similarities in terms of investment options (annuities and mutual funds), employee contributions, and catch-up contributions for participants aged 50 years old and up.

The 403(b) plan's best feature is the higher total contribution limit of $69,000 in 2024. This allows contributors to accumulate more funds in the retirement account.

On the other hand, the 457(b) plan has more accessibility because funds can be withdrawn without fees when the employee leaves the company.

The kind of retirement plan you can choose usually depends on the type of company or organization you work for.

Some employers offer only one option, but others can offer both. In the latter case, consider your alternatives carefully.

The most appropriate plan depends on your situation and retirement goals.

If you are unsure, it is a good idea to speak with a financial advisor who can help you understand the differences between the two plans and make the best decision for your needs.
