System Eligibility and Enrollment
The Middlesex County Retirement System provides retirement benefits for active members, retirees, and inactive members of municipalities, school districts, housing authorities, water districts, and other public entities across Middlesex County.
Membership is required by law for all eligible permanent and qualifying temporary employees.
Who is Eligible?
Employees of participating units are generally eligible for membership if they:
- Work at least 20 hours per week.
- Earn a minimum of $5,000 per year.
- Hold a permanent or qualifying temporary position.
Please note: Specific eligibility rules may vary. Please contact your employer or the Middlesex County Retirement System for guidance.
Purchasing Prior Service
Once you become a member, you may be eligible to purchase prior non-membership service that was not previously credited. This can help increase your future retirement benefits.
Ineligible Employees
Employees who do not meet minimum hours or earning requirements are not eligible for membership.
Ineligible employees must participate in a deferred compensation plan (or similar plan) in accordance with federal law, including the Omnibus Budget Reconciliation Act (OBRA).
