NYCERS members belong to one of several tiers based on when they joined. The tier affects benefits, vesting, contribution rates, and — critically — how benefits are calculated for division in divorce.
Tiers 1 and 2 (Pre-1976)
- Tier 1: Membership before July 1, 1973
- Tier 2: July 1, 1973 – July 26, 1976
These are the most favorable tiers with the most generous benefit structures. Members could choose from multiple retirement plans (Career Pension, Increased-Service-Fraction, Transit 20-Year, and others), with the ability to select the highest-yielding option at retirement.
Tier 1 and 2 members are increasingly rare in the active workforce but still common among current retirees. If you're divorcing a Tier 1 or 2 retiree, the benefit is likely substantial.
Tier 3 (1976–1983)
- Membership: July 27, 1976 – August 31, 1983
- Vesting: 5 years of credited service
- Member contributions: Basic Member Contributions (BMCs) cease after 10 years of service or the 10th membership anniversary, whichever comes first
Tier 4 (1983–2012)
- Membership: September 1, 1983 – March 31, 2012
- Vesting: 5 years of credited service
- BMCs: 3% of salary for 10 years
Tier 4 is the most common tier for members currently approaching retirement. It includes several sub-plans with different retirement eligibility rules:
| Sub-Plan | Minimum Age | Service Requirement | Key Notes |
|----------|------------|-------------------|-----------|
| 62/5 Basic | 62 (or 55 with Tier Equity) | 5 years vesting | Penalty applies for early retirement under Tier Equity |
| 55/25 | 55 | 25 years of service | Additional contributions (currently 1.85%) for up to 30 years |
| 57/5 (Chapter 96) | 57 | 5 years vesting | For members joining after June 29, 1995; additional contributions for 30 years |
The sub-plan matters for divorce because it affects when the Participant can retire (and when the Alternate Payee starts receiving payments), as well as the total benefit amount.
Tier 6 (2012–Present)
- Membership: April 1, 2012 – present
- Vesting: 5 years (reduced from 10 years as of April 9, 2022)
- Full retirement age: 63
- Early retirement: Age 55 with at least 5 years of service (reduced benefit)
Tier 6 pension formula:
| Service | Formula |
|---------|---------|
| Less than 20 years | 1.67% × years of service × Final Average Salary |
| 20 or more years | 35% of FAS + 2% per year over 20 |
Example: A Tier 6 member retiring at 63 with 30 years of service would receive: 35% + (10 × 2%) = 55% of their Final Average Salary.
The 2022 vesting change from 10 to 5 years is particularly important for divorces involving newer members — previously, a member with less than 10 years of service had no vested pension to divide.
Retirement Options
When a NYCERS member retires, they choose a payment option that affects both the monthly benefit amount and survivor benefits:
| Option | Description |
|--------|------------|
| Maximum Allowance | Highest monthly payment; no survivor benefit — all payments stop at Participant's death |
| Option 1 | Joint-and-Survivor 100% — beneficiary receives the same monthly amount after Participant dies |
| Option 2 | Joint-and-Survivor with reduced percentage (25%, 50%, or 75% to beneficiary) |
| Option 3 | 5-Year Certain — if Participant dies within 5 years of retirement, beneficiary receives balance |
| Option 4 | 10-Year Certain — same as Option 3 but with 10-year guarantee period |
| Option 5 | Pop-Up Joint-and-Survivor — if beneficiary predeceases Participant, benefit "pops up" to maximum amount |
Why this matters for divorce: If the DRO requires the Participant to select a specific option naming the Alternate Payee as beneficiary, this must be done before the retirement benefit is finalized. Under NY Retirement and Social Security Law § 610(f), once a retirement benefit is finalized, the option selection cannot be changed. This is permanent. If you miss this window, it's gone.
