Retirement — Gov & Nonprofit
About this plan
A 457(b) governmental deferred compensation plan lets public-sector employees save for retirement on top of any 403(b) or 401(a) they already have — with completely separate IRS contribution limits. NBS administers 457(b) plans for state and local government employers, including plan document maintenance, compliance, and participant recordkeeping.
What's Included
For Employers
A 457(b) is one of the most effective recruitment and retention tools available to government employers. Employees can contribute on top of any existing plan — NBS handles all the administration and compliance so you don't have to.
For Participants
Your 457(b) lets you save more for retirement beyond your other plans, with no early withdrawal penalty. Contributions go in pre-tax, grow tax-deferred, and are available when you separate from service.
