403(b) vs 401(k) in 2026

Same tax rules. Often wildly different fees. Here is what nobody tells teachers and nurses about their retirement plan.

If you work for a nonprofit, school, or hospital, you have a 403(b). If your employer offers only annuity-based products, your plan may cost you $100,000 or more over your career. Here is how to tell and what to do about it.

Watch out for these providers

If your 403(b) provider is AXA Equitable, Voya, Lincoln Financial, VALIC, or Equitable Financial, you are likely in an annuity contract with 1.5-3% all-in annual costs. That is 10 to 30 times more expensive than a low-cost index fund.

The 15-year rule: a 403(b)-only advantage

If you have 15+ years of service at the same qualifying employer, you can contribute an extra $3,000/year to your 403(b), up to a $15,000 lifetime cap. This does not exist in the 401(k).

If your employer offers both plans

Hospitals, universities, and large nonprofits sometimes offer both a 403(b) and a 401(k). The decision rule is simple: compare the investment options and fees. The cheaper plan with index funds usually wins. Get every employer match before making that choice.

Frequently asked questions

What is the difference between a 403(b) and a 401(k)?
403(b) plans are offered by nonprofits, schools, and hospitals; 401(k) plans are for for-profit companies. Contribution limits and tax benefits are identical at $23,500 for 2026. The practical difference is that many 403(b) plans use annuity contracts with 1.5-3% annual fees, while modern 401(k) plans often offer index funds at 0.03-0.1%. Over a career, that fee difference can cost six figures.
Why are 403(b) fees so high?
403(b) plans were legally required to use annuity contracts until 1974. Insurance companies built distribution networks into schools and hospitals that persist today. Teachers are still cold-called by reps from AXA Equitable, Voya, Lincoln Financial, VALIC, and Equitable Financial who sell annuity-wrapped 403(b)s paying the rep commission. These products often carry 1.5-3% all-in annual costs. 401(k) plans have been reformed through litigation and competition toward low-cost index funds.
What is the 403(b) 15-year rule?
Employees with 15 or more years of service at the same eligible employer (schools, hospitals, church-related orgs) can contribute an extra $3,000 per year to their 403(b). The lifetime cap is $15,000. This stacks on top of the $23,500 standard limit and the $7,500 age-50+ catch-up, giving a maximum 2026 403(b) contribution of $34,000 for qualifying employees over age 50.
What is the 2026 403(b) contribution limit?
$23,500 for both 403(b) and 401(k) plans in 2026. The catch-up contribution for those 50 and over is an additional $7,500 (or $11,250 for ages 60-63 under SECURE 2.0). The 403(b)-only 15-year rule allows an extra $3,000/year for eligible long-service employees.
Should I use my 403(b) or 401(k) if my employer offers both?
Compare the investment options and fees in each plan. The plan with lower-fee index funds usually wins. If only one plan has an employer match, contribute enough to capture that match first. If both match, get both matches, then direct additional contributions to the lower-fee plan.
Can I roll a 403(b) into a 401(k) or IRA?
Yes. 403(b) to 401(k) rollovers and 403(b) to Traditional IRA rollovers are both permitted. Use a direct rollover (trustee-to-trustee transfer) to avoid the 20% withholding that applies to indirect rollovers. Rolling to an IRA typically gives you more investment choices and lower fees.
