The 403b plan is a type of retirement savings plan designed for certain employees, such as those in education, government, and certain non-profit organizations.
Contributions to a 403b plan are made with pre-tax dollars, reducing your taxable income for the year.
You can contribute up to $19,500 in 2022, with an additional $6,500 if you're 50 or older.
The money in your 403b plan grows tax-deferred, meaning you won't pay taxes on the investment earnings until you withdraw the funds.

What Is a 403b and 401k?
A 403b is a type of retirement savings plan designed for certain employees, such as those in education, healthcare, and non-profit organizations. It's similar to a 401k, but with some key differences.
Both 403b and 401k plans are tax-deferred, meaning you won't pay taxes on the money until you withdraw it in retirement. This can help your savings grow faster over time.
What Is a 403b?
A 403b is a type of retirement plan designed for certain employees, such as those in public education, healthcare, and non-profit organizations.
It's similar to a 401k in that it allows employees to contribute a portion of their paycheck to a retirement account on a pre-tax basis.
Contributions are made with pre-tax dollars, reducing the employee's taxable income for the year.
The money grows tax-deferred, meaning the employee won't pay taxes on the earnings until withdrawal.
Employers may also offer matching contributions to incentivize employees to participate in the plan.
The 403b plan is governed by the IRS and must meet specific requirements to qualify as a qualified plan.
These plans are also known as tax-sheltered annuity plans, which can provide a source of income in retirement.

What Is a 401k?
A 401k is a type of retirement savings plan that many employers offer to their employees. It allows you to contribute a portion of your paycheck to a retirement account on a pre-tax basis.
A 401k plan is sponsored by an employer, and typically, employees can start contributing to it as soon as they're hired. The employer may also match a portion of your contributions, which is essentially free money that can add up over time.
The contributions you make to a 401k are tax-deferred, meaning you won't pay taxes on them until you withdraw the money in retirement. This can help reduce your taxable income and lower your tax bill each year.
The money in a 401k grows tax-free, and you can withdraw it starting at age 59 1/2 without penalty. However, you'll still need to pay taxes on the withdrawals, which can be a good thing because it means you'll have a lower tax rate in retirement.

Similarities and Differences
Just like 401(k) plans, 403(b) plans are a type of retirement savings plan that allows you to save for the future on a tax-deferred basis.
The most notable similarity between 403(b) and 401(k) plans is that they both offer some level of employer matching contributions, which can significantly boost your savings over time.
Some nonprofits offer employees the option between a 403(b) and a 401(k), which can make understanding their differences important for these workers.

Similarities Between 403b and 401k
Both 403b and 401k plans are employer-sponsored retirement savings plans that offer tax benefits to employees.
They are both subject to the same annual contribution limits, which are $19,500 in 2022, with an additional $6,500 catch-up contribution allowed for employees 50 and older.
Contributions are made with pre-tax dollars, reducing the employee's taxable income for the year.
Employers can also make matching contributions to both types of plans, which can significantly boost an employee's retirement savings.
These contributions are made in addition to the employee's own contributions and are also tax-deferred.

Differences Between 403b and 401k
The most significant difference between 403(b) and 401(k) plans is that 403(b) plans can only be offered to workers by nonprofits. Some nonprofits offer employees the option between a 401(k) and a 403(b), making understanding their differences important for these workers.
403(b) plans are legally restricted to annuities and mutual funds, while 401(k)s often include a broader range of investment options such as mutual funds, ETFs, stocks, and bonds.
Nonprofits are the only organizations that can offer 403(b) plans, making them a distinct option for certain employees.

Eligibility and Contributions

Both 403(b) and 401(k) plans have eligibility provisions that define when employees can join and receive employer contributions. In general, 401(k) plans have more flexible options.
For 403(b) plans, all employees must be immediately eligible upon their hire date, with limited exceptions. This is due to a "universal availability" requirement.
On the other hand, 401(k) plans can have an age requirement of up to 21 and a service requirement of up to 1 year (12 months) in which the employee performs at least 1,000 hours of service. Additionally, employee groups can be excluded if coverage testing can pass.
Here's a comparison of contribution requirements for 403(b) and 401(k) plans:
Both 403(b) and 401(k) plans are subject to annual testing to ensure business owners and other Highly Compensated Employees (HCEs) do not disproportionately benefit.
Eligibility
Eligibility for 401(k) and 403(b) plans is a crucial aspect to understand, as it determines who can participate and when. Both plans must include eligibility provisions, but 401(k) plans have more flexible options.
In general, 403(b) plans have stricter eligibility requirements, with all employees immediately eligible upon their hire date, thanks to the "universal availability" requirement. This means no age or service requirements can be imposed on elective deferrals.
For 401(k) plans, age and service requirements are more flexible. Employees must be at least 21 years old, and a service requirement of 1 year (12 months) with at least 1,000 hours of service is typical. However, employee groups can be excluded if coverage testing can pass.
Here's a comparison of eligibility requirements for 403(b) and 401(k) plans:
Understanding these eligibility requirements is essential to ensure your plan complies with regulations and benefits your employees appropriately.
Which Is Better?
Choosing between a 403(b) and a 401(k) plan can be a bit tricky, but it's worth considering if you have access to both. The main difference between the two plans is the investment diversity offered by the 401(k).
The contribution cap remains the same across both plans, so you can save up to the same amount regardless of which one you choose.
Investment Options
Investment options are a crucial aspect of retirement plans. 401(k) plans typically offer a wide range of investment options, including mutual funds, ETFs, stocks, and bonds.
Most 403(b) plans, however, have a more limited number of investment options, mainly restricted to annuities and mutual funds.
If you have a 401(k) plan, you can invest in a variety of assets to create a diversified portfolio.
403(b) plans, on the other hand, are legally restricted to annuities and mutual funds.
When choosing your investments, consider your risk tolerance and time horizon to ensure you're making informed decisions.
A diversified portfolio can help protect your retirement savings from market volatility.
Here's a comparison of the typical investment options available in 401(k) and 403(b) plans:
Keep in mind that 403(b) plans may have higher fees and expenses compared to 401(k) plans.
Tax and Withdrawal Rules
Pre-tax dollars are used to fund traditional 401(k) and 403(b) retirement plans, reducing your taxable income in the year you make the contribution.
Contributions to these plans are made before taxes, which means you save on income taxes in the year you make the contribution. This can be a significant tax advantage, especially for high-income earners.
Rollovers or transfers from a 403(b) into a traditional retirement plan, such as a 401(k), are usually tax-free since they are both funded with pre-tax dollars.
However, if you roll a traditional 403(b) plan into a Roth account, the funds will be subject to income tax because Roth accounts use after-tax dollars.
A direct rollover of a 403(b) plan into a traditional IRA, 401(k), another 403(b), or a government-eligible 457 plan can be done with no tax consequences.
But, if you roll it into a Roth account, like a Roth IRA, the distribution will be considered taxable income.
401(k) and 403(b) plans are tax-advantaged, meaning workers can preserve more of their investment growth for retirement rather than losing some to taxes each year.
Most contributions to 401(k) and 403(b) plans are made on a pre-tax basis, which helps workers pay less in taxes that year.
Many 401(k) and 403(b) plans also accept Roth contributions, which are made after an employee has already paid taxes on their income.

Both 401(k) and 403(b) plans penalize workers who withdraw from their accounts before age 59 ½ with a 10% tax penalty, in addition to ordinary income taxes.
Withdrawing funds before age 59 ½ may subject you to a 10% early withdrawal penalty, in addition to federal and state taxes on the money.

Rollovers and Transfers
A direct rollover is the safest way to transfer funds from a 403(b) to a 401(k), as it's not subject to tax withholding.
This type of transfer is done trustee to trustee, electronically transferring the funds from the old plan to the new one, without the IRA owner receiving a check.
If you receive a check in an indirect rollover, 20% of the transfer amount will be withheld for taxes.
You'll need to make up the withheld amount to avoid taxes and penalties, which can be a hassle.
A 403(b) to 401(k) rollover example illustrates this point: if you receive a check for $8,000 after a 20% withholding, you'll need to come up with $2,000 from other sources to complete the rollover.
The funds must be re-deposited into the new IRA within 60 days to avoid penalty, so be sure to plan ahead.
If you're under age 59½, you'll also face an early distribution penalty of 10% on the additional $2,000 you need to come up with.

Employer and ERISA Coverage
Employer matching contributions are a great benefit for 401(k) and 403(b) plans, but they work differently. For 401(k) plans, employers may contribute to their employees' plans in addition to employee contributions, often in the form of matching contributions up to 5% of their wages.
Employer matching contributions are less common in 403(b) plans, but even a modest match can be valuable. Many for-profit employers offer a match, often up to a certain percentage of your salary.
ERISA-covered plans, which include 401(k) plans, must pass certain nondiscrimination tests and file a Form 5500 each year. This means they must satisfy most of the nondiscrimination rules that apply to other plans, including passing the minimum coverage test and the ACP test if they include matching contributions.
Here are the key differences between ERISA-covered and non-covered 403(b) plans:
- ERISA-covered plans are required to pass the minimum coverage test and the ACP test if they include matching contributions.
- Non-covered 403(b) plans are exempt from the nondiscrimination requirements and do not need to pass the ADP test.
Employer Contributions
Employer contributions can be a game-changer for your retirement savings. Both 401(k) and 403(b) plans can offer employer matching or nonelective contributions, which can significantly boost your account balance over time.
Many 401(k) plans offer employer matches, often up to a certain percentage of your salary, making it a valuable addition to your retirement savings account. Employer matching contributions are also more common in 401(k) plans compared to 403(b) plans.
However, some 403(b) plans may offer employer contributions, although they may be less common or less substantial. Even a modest employer match can contribute to long-term financial security.
The maximum contribution limits for employer matching are generally the same for both plans, but the rules for employer contributions can be more complex. Sponsors of 403(b) plans have the option to provide additional benefits to terminated participants, which can be a unique advantage.
Here are some key points to remember about employer contributions:
- 401(k) plans are more likely to offer employer matches, often up to a certain percentage of your salary.
- 403(b) plans may offer employer contributions, although they may be less common or less substantial.
- The maximum contribution limits for employer matching are generally the same for both plans.
- Sponsors of 403(b) plans have the option to provide additional benefits to terminated participants.
It's essential to understand the specific rules and regulations surrounding employer contributions for your plan, as they can impact your retirement savings significantly.
ERISA Coverage Risks
If your 403(b) plan is covered by ERISA, you'll need to comply with certain requirements. ERISA-covered plans must pass nondiscrimination tests and file a Form 5500 each year, similar to 401(k) plans.

This means you'll need to ensure your plan is meeting certain standards, such as the minimum coverage test and the ACP test for matching contributions. ERISA-covered plans are also subject to fiduciary rules.
One key exception is the ADP test, which normally applies to salary deferrals. However, 403(b) plans are exempt from this test, allowing highly compensated employees to maximize their deferrals.
If your plan includes employer contributions, you'll need to pass the minimum coverage test and the ACP test. This ensures that your plan is providing benefits to a wide range of employees, not just highly compensated ones.
Older plan accounts can be disregarded for reporting purposes if they meet certain requirements. These requirements include:
- The contract or account was issued to a current or former employee before January 1, 2009;
- The employer ceased to have any obligation to make current contributions, and in fact ceased making contributions to the contract or account before January 1, 2009;
- All of the rights and benefits under the contract or account are legally enforceable against the insurer or custodian by the individual owner of the contract or account without any involvement by the employer;
- The individual owner of the contract is fully vested in the contract or account.
It's essential to note that 403(b) plans are generally prohibited from investing in individual stocks or bonds, collective investment funds, and self-directed brokerage accounts.
Best Practices and Considerations
Contributing to a 403(b) plan is a great way to start saving for retirement, but you may also have access to a 401(k) plan. To maximize your retirement savings, consider contributing up to 15% of your income to your retirement account each year.

Paying off debt and building an emergency fund can also help provide for a secure retirement. This can help reduce your living expenses during retirement and ensure you don't have to pull money from your retirement account early.
If you have access to both a 401(k) and a 403(b), focus on the investment options available in each plan. 403(b) plans typically have limited investment options, so you may want to choose the 401(k) plan if it offers more robust investment options.
Employer matching is a key consideration when choosing between a 401(k) and a 403(b). Both plans can offer employer matching, but not all plans do, so be sure to take advantage of it if it's available.
To avoid overcontributing to your retirement accounts, remember that you're limited to the combined total contribution amount across all plans. In 2025, this limit is $23,500, plus any catch-up contributions you're eligible for.
Here are some key considerations to keep in mind when choosing between a 401(k) and a 403(b):
