NYC TRS members belong to one of six tiers based on when they joined the system. The tier affects vesting, retirement eligibility, contribution rates, benefit formulas, and — critically for divorce — how the pension is calculated when divided.
Tier I (Pre-1960s)
- Membership: Before approximately 1960
- Vesting: 5 years
- Full Retirement: Age 55 with 30 years of service
- Contributions: None (pre-contributory tier)
- Key Features: Highest benefit multipliers; unreduced benefits at age 55/30 years; possible Social Security offset
Tier I members are increasingly rare in the active workforce but still common among current retirees. If you're divorcing a Tier I retiree, the pension benefit is likely substantial.
Tier II (1960s–1983)
- Membership: Approximately 1960s through 1983
- Vesting: 5 years
- Full Retirement: Age 55 with 30 years of service
- Contributions: None (pre-contributory tier)
- Key Features: Similar to Tier I; service retirement available after 5 years of vesting
Tier II is also becoming rare among active members.
Tier III (1983)
- Membership: Approximately 1983 through September 1, 1983 (very narrow window)
- Vesting: 5–10 years
- Full Retirement: Age 55 with 30 years of service
- Contributions: 3% of salary until 10 years of service or membership (whichever comes first)
- Key Features: Pension reduced by 50% of Social Security supplement; transferable tier status for members moving between NYC systems
Tier III is a small cohort due to the short enrollment window.
Tier IV (September 1, 1983 – December 31, 2009)
- Membership: September 1, 1983 through December 31, 2009
- Vesting: 5 years of credited service
- Full Retirement: Age 55 with 30 years of service (unreduced); or Age 62 with 5 years (unreduced)
- Contributions: 3% of salary until 10 years of service (Basic Member Contributions); contributions cease after 10 years
Tier IV Pension Formula:
| Service | Formula |
|---------|---------|
| Less than 20 years | 1.67% × years of service × Final Average Salary |
| 20–29 years | 2.0% × years of service × Final Average Salary |
| 30 or more years | 60% of FAS + 1.5% per year over 30 |
Final Average Salary (FAS) for Tier IV: Average of the highest 3 consecutive school years of earnings.
Example: A Tier IV member retiring at age 60 with 25 years of service and a Final Average Salary of $100,000 would receive:
25 × 2.0% × $100,000 = $50,000 per year (before option reduction)
Tier IV is the most common tier for members currently approaching retirement or recently retired.
Tier V (January 1, 2010 – March 31, 2012)
- Membership: January 1, 2010 through March 31, 2012
- Vesting: 10 years of credited service
- Full Retirement: Age 57 with 30 years of service; earlier retirement available with actuarial reduction
- Contributions: 3.5% of salary for life (no 10-year cap)
- Key Features: Overtime capped at $15,000 in 2010, increasing 3% per year; 10-year vesting requirement
Tier V is a small cohort due to the short enrollment window.
Tier VI (April 1, 2012 – Present)
- Membership: April 1, 2012 and later
- Vesting: 10 years of credited service
- Full Retirement: Age 63 (unreduced); early retirement available at age 55+ with actuarial reduction
- Contributions: 3%–6% of salary for life, based on salary level:
- 3% for salary ≤$43,000
- Graduated increases up to 6% for salary exceeding the Governor's salary (~$250,000)
Tier VI Pension Formula:
| Service | Formula |
|---------|---------|
| Less than 20 years | 1.67% × years of service × Final Average Salary |
| 20 or more years | 35% of FAS + 2.0% per year over 20 |
Final Average Salary (FAS) for Tier VI: Average of the highest 5 consecutive school years of earnings (not 3).
Example: A Tier VI member retiring at age 63 with 25 years of service and a Final Average Salary of $100,000 would receive:
35% + (5 × 2.0%) = 45% of FAS = $45,000 per year
Tier VI is the current entry tier for all new NYC teachers.
Retirement Payment Options
When an NYC TRS member retires, they select 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 the member's death |
| Option 1 | Joint-and-Survivor 100% — named beneficiary receives the same monthly amount after the member dies |
| Option 2 | Joint-and-Survivor with reduced percentage (e.g., 50%, 75%) to beneficiary |
| Option 3 | 5-Year Certain — if member dies within 5 years of retirement, beneficiary receives the balance |
| Option 4 | 10-Year Certain — same as Option 3, but with a 10-year guarantee period |
| Pop-Up Options | If beneficiary predeceases the member, benefit "pops up" to maximum amount |
Critical 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 and irreversible. If you miss this window, the survivor protection is lost forever.
