403(b) limits match 401(k) limits. Some 403(b) plans allow an additional 15-year catch-up for long-tenured employees (up to $3,000/yr, max $15,000 lifetime).

403(b) vs 401(k)
Who qualifies: 403(b) is for public school employees, nonprofits (501(c)(3)), and some ministers. 401(k) is for private-sector employers.
Same contribution limits as 401(k) since 2001. Both offer traditional (pre-tax) and Roth options.
15-year rule: Employees with 15+ years of service at the same eligible employer may contribute an extra $3,000/yr (up to $15,000 lifetime).
