The Roth 403(b) is a powerful retirement savings tool for employees of public schools and certain non-profits. Its main advantage? Tax-free withdrawals in retirement, offering a shield against future income tax hikes. This guide simplifies what you need to know.
What is a Roth 403(b)?
A 403(b) plan (or 403(b) Tax-Sheltered Annuity Plan) is for public education, specific 501(c)(3) non-profit employees, and some ministers. The "Roth" option changes its tax treatment:
- Traditional 403(b): Pre-tax contributions lower current taxable income. All distributions (contributions and earnings) are taxed in retirement.
- Roth 403(b): Your contribution is taxable now (after-tax dollars) at your current tax rate. Earnings on contributions grow tax-free, and qualified withdrawals in retirement are completely tax-free.
Roth 403(b) vs. Traditional 403(b)
The fundamental difference lies in how and when you pay taxes:
Feature | Traditional 403(b) | Roth 403(b) |
Contributions | Pre-tax dollars (reduces current taxable income) | After-tax dollars (no immediate tax benefit) |
Employer match | Taxable upon withdrawal | Taxable upon withdrawal (unless Roth employer contributions elected) |
Growth on investments | Tax-deferred (taxed upon withdrawal) | Tax-free |
Withdrawals in retirement | Taxed as ordinary income | Tax-free (if qualified) |
Required Minimum Distributions | Required at age 73 | No RMDs during the original owner's lifetime (as of 2024) |
Income limits | None | None |
2025 Contribution Limits & Catch-Ups
Employee Contributions
Contributions are usually made via elective salary deferrals. These annual limits apply to combined traditional and Roth 403(b) contributions:
Limit Type | 2025 Amount | How It Works |
Standard elective salary deferrals | $23,500 | Total contribution you can send from salary, Roth or pre-tax. |
Age 50+ “standard catch-up contribution limit” | $7,500 (total $31,000) | Lets workers 50 or older send in more dollars. |
Age 60-63 "Higher" catch-up contribution (New for 2025) |
$11,250 (total $34,750) | Enhanced catch-up contribution limits for individuals ages 60 to 63. |
Special 15-year catch-up contribution | Up to $3,000 per year ($15k lifetime cap) | Available if you’ve served the same qualified employer for 15 years. |
If you qualify for both catch-up provisions, the IRS requires that the 15-year catch-up be applied first, followed by the age-based catch-up.
Employer Contributions
Many employers offer matching contributions.
- Historically: Employer funds went into a pre-tax account, taxable at distribution.
- SECURE 2.0 Act Update: Employers can now choose to offer employer contributions (including matching contributions) on a Roth (after-tax) basis. If offered and elected, you'd pay income tax on these employer dollars upfront, but they (and their earnings) could be withdrawn tax-free in retirement. This is an optional employer feature.
Tax-Free Withdrawals: The Roth 403(b) Promise
The main appeal of a Roth 403(b) is tax-free withdrawals in retirement. To qualify:
- The 5-Year Rule: The first Roth contribution to the plan must have been made at least five taxable years prior (clock starts Jan 1st of the first contribution year).
- And One of These:
- You are age 59 ½ or older.
- You become disabled.
- Distribution is to your beneficiary after your death.
Meet both, and all your distributions in retirement (contributions and earnings) are federally tax-free (most states follow suit).
Non-Qualified Distributions
Need funds early?
- Your Roth contributions (principal) are always tax-free and penalty-free.
- Earnings on contributions are taxed as income and may face a 10% early withdrawal penalty if under 59 ½ (unless an exception applies).
Roth 403(b) and RMDs
Thanks to the SECURE 2.0 Act, Roth 403(b) accounts are NO LONGER subject to Required Minimum Distributions (RMDs) during the original owner's lifetime. This lets your money grow tax-free longer. (Beneficiaries will still have RMD rules.)
Advantages of Roth 403(b) Plans
1. Tax-Free Growth and Withdrawals
The most obvious benefit is never paying taxes on your investment earnings. Over decades, this can mean significantly more money in your pocket during retirement.
2. No Income Limitations
Unlike Roth IRAs, which phase out for higher income earners, Roth 403(b)s have no income restrictions. This makes them valuable for high-income professionals who want Roth benefits.
3. Higher Contribution Limits
You can contribute more than twice as much to a Roth 403(b) ($23,000 in 2025) as you can to a Roth IRA ($7,000 in 2025), allowing for accelerated tax-free retirement savings.
4. Potential for Double Catch-Up Contributions
The possibility of using both the 15-year service catch-up and the age 50+ catch-up creates a powerful savings opportunity for long-serving employees.
5. No Lifetime RMDs
Thanks to the SECURE 2.0 Act, Roth 403(b) accounts are no longer subject to Required Minimum Distributions during the original owner's lifetime, allowing your money to grow tax-free for as long as you wish.
6. Tax Diversification
Having both taxable and tax-free money in retirement gives you flexibility in managing your tax situation each year.
7. Protection Against Future Tax Increases
If tax rates rise in the future (which many financial experts predict), having tax-free income streams becomes even more valuable.
Potential Drawbacks of Roth 403(b) Plans
1. No Immediate Tax Benefits
Unlike traditional pre-tax contributions, Roth contributions don't reduce your current tax bill, which can make budgeting tighter.
2. Limited Investment Options
Many 403(b) plans have more restricted investment options than 401(k)s or IRAs, often limited to annuity products from insurance companies.
3. Employer Match Goes into Traditional 403(b)
Even if you make Roth contributions, any employer matching funds must go into a traditional pre-tax account, creating a mixed tax situation in retirement, unless your employer offers the Roth employer contribution option.
Strategies to Maximize Your Roth 403(b)
Start Early
The power of tax-free compound growth becomes more significant over time. Starting your Roth 403(b) contributions early in your career, when your tax rate might be lower anyway, maximizes this benefit.
Use Catch-Up Provisions
If you qualify for the 15-year service catch-up contribution, use it before the age 50+ catch-up. This allows you to potentially exceed the standard contribution limits.
Consider a Roth Conversion Ladder
If you have existing traditional 403(b) assets, you might strategically convert portions to Roth over several years, managing the tax impact while increasing your tax-free retirement funds.
Plan for the Five-Year Rule
Remember that each Roth 403(b) account has its own five-year aging requirement for tax-free earnings withdrawals. Plan accordingly, especially if changing employers.
Consider a Roth IRA Rollover for Maximum Flexibility
Even though Roth 403(b) accounts are now exempt from RMDs during your lifetime, rolling over to a Roth IRA might still offer advantages like broader investment options and simplified account management in retirement.
Traditional vs. Roth 403(b): Which Is Right for You?
The traditional vs. Roth decision depends largely on your tax situation now versus later. Here's a simple framework to help decide:
Choose Traditional 403(b) If: | Choose Roth 403(b) If: |
You're in a high tax bracket now | You're in a low tax bracket now |
You expect to be in a lower tax bracket in retirement | You expect to be in a higher tax bracket in retirement |
You need the immediate tax deduction | You can afford to pay taxes now |
You're close to retirement | You have many years until retirement |
You believe tax rates will decrease | You believe tax rates will increase |
You want to minimize current taxes | You want tax-free income during retirement |
Real-World Example: The Long-Term Impact
Let's compare the long-term outcomes for two teachers, both earning $60,000 annually and contributing $12,000 per year to their retirement plans:
- Teacher A chooses a traditional 403(b), reducing their taxable income to $48,000
- Teacher B selects a Roth 403(b), paying taxes on their full $60,000 salary
Assuming a 24% tax bracket during working years, a 7% annual return, and 25 years of contributions:
Scenario | Traditional 403(b) Teacher A |
Roth 403(b) Teacher B |
Annual contribution | $12,000 | $12,000 |
Tax savings during working years | $2,880/year ($72,000 total) | $0 |
Account value after 25 years | $760,513 | $760,513 |
Taxes due on withdrawals | $182,523 (24% bracket) | $0 |
Net retirement value | $577,990 | $760,513 |
Retirement Income Advantage | $0 | +$182,523 |
This simplified example assumes tax rates remain constant. Throughout their lifetime, Teacher A receives $110,523 less than Teacher B (Income advantage of $182,523 minus Tax Savings of $72,000). For illustrative purposes only. Actual results will vary.

Frequently Asked Questions
Can I contribute to both a Roth 403(b) and a Roth IRA?
Yes, you can generally contribute to both a Roth 403(b) and a Roth IRA in the same year, as they have separate contribution limits. However, your ability to contribute to a Roth IRA is subject to income limitations set by the IRS, while Roth 403(b) contributions through your employer typically do not have such income restrictions for eligibility.
What happens to my Roth 403(b) if I change jobs?
You have several options:
- Leave it with your former employer (if the plan allows)
- Roll it into your new employer's Roth 401(k) or 403(b) (if available)
- Roll it into a Roth Individual Retirement Account (usually the most flexible option)
- Take a distribution (generally not recommended due to potential penalties)
Are there penalties for early withdrawals?
Yes. Withdrawals before age 59½ may be subject to a 10% early withdrawal penalty, plus income taxes on any earnings withdrawn (unless an exception applies). Your contributions (but not earnings) can be withdrawn penalty-free, though this may be administratively difficult in some plans.
How does a Roth 403(b) differ from a 401(k)?
They're nearly identical regarding contribution limits, tax treatment, and rules. The primary difference is eligibility; 403(b) plans are for nonprofit and public sector employees, while 401(k) plans are for private-sector workers.
Can I convert my traditional 403(b) to a Roth 403(b)?
If your plan permits in-plan Roth conversions, yes. You'll pay income tax on the converted amount in the year of conversion. This can be a strategic move if you anticipate higher tax rates in the future or during a year when your income is unusually low.
