Beginning January 1, 2026, several significant updates to annual contribution limits and catch-up rules for the UC 403(b) and 457(b) Plans will take effect. These updates will apply to employees who will be age 50 or older in 2026 with 2025 earnings that exceed $150,000.  Some of the changes may directly affect the rules for whether their catch-up contributions are pretax (with taxes paid when they withdraw funds) or Roth (with after-tax contributions now and potential tax-free withdrawals in retirement).

Key Changes Effective January 1, 2026—Employee Action May Be Required


  1.  New 2026 contribution limits
Eligible participants may contribute up to $24,500 to each plan (pretax and/or Roth), plus an $8,000 age-50+ catch-up to each plan (see section 2 below for more information), for a total of $32,500 per plan or $65,000 total (standard and age-50+ catch-up combined) across both plans.  Employees’ 2025 contribution amounts will automatically carry over into 2026.
  2.  Required Roth catch-up contributions for high earners
Under SECURE 2.0, if a participant’s 2025 Social Security (FICA) wages exceed $150,000, all age-50+ catch-up contributions made in 2026 must be Roth.  Regular contributions up to $24,500 may still be pretax, Roth or a combination, based on the employee’s current election with Fidelity.  Catch-up contributions will be treated as Roth even if the employee did not designate them as Roth with Fidelity.
Here are some examples:

Employees’ Election with Fidelity
How 2026 Contributions Will Be Treated
All pretax
First $24,500 is pretax; amounts over $24,500 are Roth.
All Roth
All contributions are Roth.
Mix of pretax and Roth
Mix applies up to $24,500; amounts above $24,500 are Roth until the Roth catch-up limit is reached. Then, pretax and Roth deductions resume as originally elected.


  1.  New “Super Catch-Up” for participants ages 60–63
Participants who will be ages 60–63 in 2026 may contribute up to $11,250 in catch-up contributions per plan. This allows up to $35,750 per plan, or as much as $71,500 across both plans.  The enhanced “super catch-up” limit for ages 60–63 replaces the standard $8,000 catch-up noted above and is subject to the same SECURE 2.0 Roth catch-up requirement for high earners.
High earning employees who prefer to manage their pretax vs. Roth contributions more intentionally in 2026 may consider splitting contributions across both 403(b) and 457(b) plans; details are included in this participant communication<https://fwc.widen.net/s/hcv255dczc/secure-2.0-email>.

Next Steps for Employees

Participants are encouraged to:

  *   Schedule a 1:1 consultation<https://digital.fidelity.com/prgw/digital/wos/one-on-one?planSponsorId=700003> or call 1-800-558-9182 (no appointment needed) to speak with a UC-dedicated Fidelity Retirement Planner about their 2026 contribution strategy, the impact of required Roth catch-ups, modifying their elections, planning for retirement and more.  Employees can learn more about the UC 403(b) and 457(b) Plans on myUCretirement.com<https://myucretirement.com/>.
  *   Review their January 2026 contribution elections in NetBenefits<https://nb.fidelity.com/static/mybenefits/netbenefitslogin/#/login>. Deferral elections can be changed at any time on NetBenefits<https://nb.fidelity.com/static/mybenefits/netbenefitslogin/#/login> or by calling 1-800-558-9182.  However, to help ensure that their elections take effect when they intend, employees should submit their election changes according to the pay frequency schedule on the UCPath 2026 payroll calendar<https://ucop.edu/ucpath-center/_files/mypath/calendar/rsp-enrollment-change-dates-2026.pdf> or the UCPath 2026 payroll calendar for LBNL employees<https://ucop.edu/ucpath-center/_files/mypath/calendar/lbnl-rsp-enrollment-change-dates-2026.pdf>.
If no changes are made, age-50 catch-up contributions for high earners will automatically be processed as Roth—as required by SECURE 2.0.
