About 70 million Americans face the choice between 401k and 403b employer-sponsored retirement plans. For-profit companies offer 401(k) plans that come with more investment choices such as mutual funds, ETFs, and stocks. The 403(b) plans hold about $1.3 trillion in assets. These plans are made for employees working in non-profit organizations, public schools, churches, and government entities. Understanding the unique features of each plan helps you make smart retirement decisions. Let’s take a closer look at the differences between 401k and 403b plans to help you find which option arranges better with your career path and retirement goals.
Key Similarities Between 401(k) and 403(b)
401(k) and 403(b) plans work as valuable retirement options that share many core features, even though they serve different sectors.
These employer-sponsored retirement plans let workers save money while putting off taxes on what they contribute and earn until they take it out. Both 401(k) and 403(b) plans give tax benefits to employees and their employers.
The plans have similar contribution rules. Participants can put in up to $23,500 each year through their regular contributions in 2025. People who are 50 or older can add $7,500 more as catch-up contributions. When you count employer contributions too, the total limit hits $70,000 for both types of plans.
You can contribute to these plans in several ways:
- Pre-tax money that cuts your current taxable income
- Roth contributions you pay taxes on now but withdraw tax-free later
- Employer matching and extra contributions
The rules about taking money out work much the same way. You can access your funds when:
- You leave your job
- Death occurs
- You become disabled
- The plan ends
The plans also let you take hardship withdrawals if the IRS agrees you have an “immediate and heavy financial need”. Loans work about the same way too – you usually need to pay them back within five years at a rate just above prime, unless you’re buying a primary home.
Traditional 401(k) and 403(b) accounts must follow Required Minimum Distribution (RMD) rules. But starting in 2024, Roth accounts in these employer plans no longer need RMDs.
Investment options look similar in both plans. They usually give you a menu of pre-picked choices, mostly mutual funds. The biggest difference is that 403(b) plans tend to offer more annuity options.
These shared features mean that no matter which plan you have, you can build your retirement savings with tax advantages and enjoy the same contribution and withdrawal benefits.
Main Differences Between 401(k) and 403(b)
401(k) and 403(b) plans share basic functions but have several important differences that affect retirement planning strategies.
The basic difference comes down to who can use them. 401(k) plans are offered mainly in private sector companies that make profit, while 403(b) plans are exclusively available to employees of public schools, churches, tax-exempt 501(c)(3) organizations, and certain governmental entities. Some bigger organizations like universities sometimes offer both plans to their employees.
These plans have substantially different investment choices. 403(b) plans usually have fewer options and have traditionally focused on annuities and mutual funds through custodial accounts. 401(k) plans give you more investment choices including stocks, bonds, and mutual funds. Federal regulations limit 403(b) plans from investing in individual stocks, bonds, or collective investment trusts, which explains these restrictions.
403(b) plans come with a special catch-up option that you won’t find in 401(k) plans. If you work for 15 or more years at qualifying organizations, you can put in an extra $3,000 each year, up to $15,000 total[84]. This benefit targets people working in educational, medical, welfare, and church organizations.
The rules are different too. Most 401(k) plans must follow ERISA rules, but many 403(b) plans from churches, public schools, and government organizations don’t have to[81]. So these exempt 403(b) plans skip the nondiscrimination testing that checks if highly paid employees get too many benefits[81].
The plans handle administration differently. 403(b) plans follow “universal availability” rules, which means almost everyone must be able to contribute whatever their time served. 401(k) plans can set age limits (up to 21) and make people work up to a year before joining.
Both plans can match employee contributions, but 403(b) plans rarely do. Employers skip matching to keep their ERISA exemption status, which matching contributions might remove[81].
How to Decide Which Plan Is Right for You
Most employers offer either a 401(k) or 403(b) based on their classification, so people rarely get to choose between them. Notwithstanding that, you might need to make this choice in specific situations.
To cite an instance, you might need to pick between plans if you work for multiple employers or if an educational institution offers both options. You’ll need to assess which plan better fits your retirement needs. Medical professionals who split their time between for-profit hospitals and non-profit clinics often face this choice.
Several practical factors come into play when comparing these plans:
Investment Priorities: 401(k) plans usually offer more variety if you value diverse investment options. A 403(b) might work better if annuities interest you as investment vehicles.
Financial Goals: Each plan’s features should arrange with your long-term goals. Many 403(b)s offer faster or immediate vesting compared to 401(k)s, which means your employer’s contributions become yours earlier.
Risk Tolerance: Your investment risk comfort level should guide your choice. 401(k)s give you more flexibility to match different risk appetites.
Service Duration: The 403(b) plans offer extra catch-up contributions if you’ve worked for a qualifying non-profit or government agency for over 15 years.
Expense Considerations: 403(b) plans often have lower expense ratios than 401(k)s because they face fewer regulations. This difference helps preserve more of your investment returns.
The law allows you to contribute to both plans at once if you have access to them. But remember that your total contributions can’t exceed the annual limit of $23,000 for 2024, plus any eligible catch-up contributions.
A financial advisor can offer great guidance based on your specific situation if you’re unsure about the best option. They’ll help assess factors like employer matching, investment options, and tax implications to boost your retirement savings.

Conclusion
401(k) and 403(b) plans are great paths to retirement security, though they serve different employment sectors. These investment vehicles have the same basic features like contribution limits, tax advantages, and distribution rules. The main difference lies in their target groups and regulatory frameworks.
Your employment sector usually determines which plan you can access. People working at for-profit companies get 401(k) plans with various investment choices. Teachers, healthcare workers, and other non-profit professionals use 403(b) plans that come with unique benefits, including special catch-up provisions.
Most people can’t pick between these plans. Yet knowing the difference helps when you’re looking at job offers or managing multiple jobs. If you’re lucky enough to have access to both options, you should look at things like investment variety, vesting schedules, and expense ratios.
The retirement scene keeps changing. These two retirement planning pillars remain crucial for millions of Americans. Whatever plan matches your career path, steady contributions and smart investment choices can lead to financial security. A chat with retirement planning experts can really help. This is especially true when you need to maximize contributions across multiple plans or adjust investment strategies based on your goals and risk comfort level.
FAQs
The primary difference is eligibility: 401(k) plans are typically offered by for-profit companies, while 403(b) plans are for non-profit organizations, public schools, and religious institutions. 401(k) plans generally offer a wider range of investment options, while 403(b) plans often focus on annuities and mutual funds.
Yes, you can contribute to both plans if you’re eligible, but your combined contributions cannot exceed the annual limit set by the IRS. For 2024, this limit is $23,000, plus catch-up contributions if you’re 50 or older.
Yes, 403(b) plans offer a special catch-up provision for long-term employees. Those with 15 or more years of service at qualifying organizations can contribute an additional $3,000 annually, up to a lifetime maximum of $15,000.
You have several options: you can roll over the balance into an IRA or a new employer’s retirement plan, leave it with your former employer if allowed, or potentially cash it out (though this may incur penalties and taxes). Be aware of any potential surrender charges or vesting schedules that may apply.
Employer matches are more common in 401(k) plans. While 403(b) plans can offer matches, they often don’t to maintain their ERISA exemption status. However, some 403(b) plans may offer other forms of employer contributions, such as non-elective contributions.
