Part-time service is service in which an employee is regularly scheduled to work less than 1,827 hours in a calendar year.

Salary Base

Sanitation Member

A member employed in a position in the uniformed-force of the NYC Department of Sanitation.

Social Security Offset

For Tier 1 and Tier 2 members only.

Social Security offset allows you to reduce some or all of your Basic Contribution Rate by the percentage taken out of your paycheck for Social Security. By doing this, you may end up with a deficit in your account.

Tier Equity

A law enacted in 2000 which enables Tier 3 and Basic Tier 4 members who do not belong to a special plan (i.e., 55/25, 57/5 and Transit 25/55) to retire with a pension reduction prior to their normal retirement age but no earlier than age 55.

Tier 4 Members with Tier 3 Rights (Tier 3/4 Members)

Tier 4 members who last joined NYCERS after July 26, 1976 and before September 1, 1983, or were otherwise made eligible, automatically became Tier 4 members on September 1, 1983. However, these members retain their Tier 3 rights and are eligible to elect Tier 3 benefits.

In the past, a Tier 3/4 Member typically exercised his or her Tier 3 rights when he or she wanted to retire prior to age 62, since there was no such provision under Tier 4. Due to enactment of Tier Equity legislation in 2000, Tier 4 members are now eligible to retire before age 62, with a lesser benefit reduction than under Tier 3. Furthermore, Tier 3 Service Retirement and Disability Retirement Benefits impose a significant reduction when the retiree reaches age 62 — i.e. the retirement benefit is further reduced by 50% of his or her primary Social Security benefit attributable to his or her Credited “City” Service.

It is not always advantageous to revert to Tier 3 for retirement purposes. However, there are Tier 3 disability provisions that may make a Tier 3/4 Member eligible for a benefit that he or she would not be eligible for under Tier 4.

Transit Authority Member

A Tier 4 member employed in the operating-force of the NYC Transit Authority and some managers.

Vesting is the right to receive future retirement benefits even if you terminate employment before you are eligible for payment of a service retirement benefit.


Any earnings paid for services rendered to an agency of the City of New York or any other public employer in New York City or New York State.
