If you work at a hospital, public school, or nonprofit, your HR department handed you a 403(b) enrollment form at some point. You can also open an IRA on your own at Fidelity, Vanguard, or Schwab, no employer required. These two accounts don't compete, they stack. But knowing which one to fill first, and how much to put into each, can realistically mean $60,000 to $100,000 more in your retirement balance over a 30-year career.

Short answer: contribute to your 403(b) up to the employer match, then max a Roth IRA if your income qualifies. Here's the full picture.

What Is a 403(b) and Who Can Open One

A 403(b) is an employer-sponsored retirement plan restricted to employees of tax-exempt organizations under IRS Section 501(c)(3): public schools, hospitals, universities, churches, and nonprofits. You can't open one on your own. If your employer doesn't offer it, it simply isn't available to you.

The 2025 contribution limit is $23,500, or $31,000 if you're 50 or older (the $7,500 catch-up matches what 401(k) participants get). Some long-tenured employees at qualifying organizations can also tap a "special 15-year catch-up" that pushes limits even higher, but HR almost never mentions it. Ask.

Most 403(b) contributions are pre-tax. Earn $80,000, contribute $10,000, and you pay income tax on $70,000 this year. The tax bill arrives at retirement when you withdraw.

Here's what most comparison articles skip entirely: a large share of 403(b) plans still default participants into insurance company annuity contracts, not mutual funds. Those products carry annual expense ratios of 1.5 to 2 percent. Compare that to 0.03 percent for the Vanguard Total Stock Market Index Fund (VTSAX) or 0.00 percent for Fidelity's FZROX. On a $200,000 balance, a 1.75-percent fee gap erases roughly $80,000 in compounding over 30 years. Check your plan's investment menu. If you see names like Lincoln Financial, Equitable, or Transamerica, ask HR whether a "custodial account" option with low-cost mutual funds is available. Many 403(b) plans include it but bury it three menus deep.

How an IRA Works: Traditional and Roth

An IRA (Individual Retirement Account) is yours alone. No employer involvement. Fidelity, Vanguard, Schwab, and even Robinhood offer IRAs with no minimums to open in 2025.

The 2025 contribution limit is $7,000, or $8,000 if you're 50 or older. Small compared to a 403(b), but the investment universe is nearly unlimited: individual stocks, ETFs, index funds, bonds, REITs. You're not stuck with whatever 12 options your plan administrator negotiated.

Two types matter:

Traditional IRA. Contributions may be tax-deductible depending on your income and whether a workplace retirement plan covers you. You pay tax on withdrawals in retirement. Required minimum distributions (RMDs) kick in at age 73.

Roth IRA. You contribute after-tax dollars now. Growth is tax-free. Qualified withdrawals in retirement cost you nothing. No RMDs during your lifetime, which makes Roth accounts the go-to tool for estate planning too. The catch is the income limit: in 2025, the phase-out begins at $150,000 for single filers. Earn above $165,000 as a single filer and direct contributions aren't allowed, though the backdoor Roth conversion sidesteps that.

If you're 30 years old earning $58,000 and expect your income (and tax rate) to rise, a Roth IRA is almost always the smarter tax move. Pay 22 percent now, owe zero at 65.

IRA vs. 403(b): Side-by-Side Comparison

| Feature | 403(b) | Traditional IRA | Roth IRA | |---|---|---|---| | Who can open it | Nonprofit/school/hospital employees | Anyone with earned income | Anyone under income limits | | 2025 contribution limit | $23,500 ($31,000 if 50+) | $7,000 ($8,000 if 50+) | $7,000 ($8,000 if 50+) | | Tax treatment | Pre-tax (typical) | Pre-tax, may be deductible | After-tax, tax-free growth | | Employer match | Often 3-6% | None | None | | Investment options | Limited to plan menu | Nearly unlimited | Nearly unlimited | | RMDs at age 73 | Yes | Yes | No | | Early withdrawal penalty | 10% before 59.5 | 10% before 59.5 | Contributions penalty-free | | Income limits | None | Deductibility phases out | Phase-out at $150K single |

The gap in investment flexibility is real. If your 403(b) offers only high-fee annuities, an IRA at Vanguard or Fidelity likely produces better after-fee returns even without the higher contribution ceiling.

Which Account to Fund First

The order of operations is straightforward once you know it.

Step one: contribute to your 403(b) up to the full employer match. If your school district matches 4 percent of a $65,000 salary, that's $2,600 in free money per year. Don't skip it.

Step two: open a Roth IRA and max it ($7,000). Do this before adding more to the 403(b). The Roth's tax-free growth and withdrawal flexibility outweigh the 403(b)'s higher contribution ceiling in most scenarios for workers under 50.

Step three: go back to the 403(b) and push toward $23,500 if you can afford to. But if your plan only offers annuity products with fees above 1 percent, consider whether a taxable brokerage account holding low-cost Vanguard ETFs might actually do better after fees. It can.

Counter-intuitively, people who work at hospitals or larger universities sometimes have access to both a 403(b) and a 457(b) plan. These limits are completely separate under IRS rules, meaning a high earner could shelter up to $47,000 per year ($23,500 plus $23,500) before catch-up contributions. Almost no one knows this. Ask your HR department whether a 457(b) is available. Ten minutes of conversation can open up $1 second full savings bucket.

Frequently Asked Questions

Can I contribute to both a 403(b) and a Roth IRA in the same year?

Yes. They're completely separate under IRS rules. In 2025 you can put $23,500 into your 403(b) and $7,000 into a Roth IRA at the same time, assuming your income falls under the Roth phase-out threshold ($150,000 for single filers). That's $30,500 in combined tax-advantaged contributions, not counting employer match dollars.

What happens to my 403(b) if I leave my job at a nonprofit?

You have four options: leave it in the plan if fees are low and it's allowed, roll it into your new employer's 403(b) or 401(k), roll it into a traditional IRA at Fidelity or Vanguard, or cash out (triggering income tax plus a 10% early withdrawal penalty before 59.5). Rolling to an IRA at a low-cost custodian is typically the best move because it opens up the full investment universe and usually cuts fees.

Can I contribute to both a 403(b) and a 401(k) if I have two jobs?

Yes, but the combined limit is shared. In 2025 your total 403(b) plus 401(k) contributions can't exceed $23,500 across both plans ($31,000 if 50 or older). The IRS imposes a 6-percent excise tax on excess contributions per year until you correct them. See our full 401(k) vs IRA comparison for details on how multiple plans interact.

What 403(b) investment options should I actually choose?

Prioritize index funds with expense ratios under 0.20 percent: a total US stock market fund, a broad international fund, and possibly a bond index fund depending on your age. If your plan only lists variable annuities from Equitable or Lincoln Financial, ask HR for the custodial account option, which most plans legally must provide. Avoid any fund with a 12b-1 fee or a surrender charge period longer than five years.

Is a 403(b) better than a Roth IRA for a teacher early in their career?

For a new teacher under 35 who isn't certain they'll stay long enough to vest in a pension (typically 5 to 10 years), a Roth IRA wins on flexibility: it follows you to any job, it grows tax-free, and you can withdraw your contributions penalty-free in a pinch. Contribute to the 403(b) only up to the employer match, then max the Roth. Once you've stayed long enough to be confident you'll vest, revisit the split.
