Bottom line
Tier VI ordinary disability generally requires 10 years of credited service. Accident disability can waive that service threshold when incapacity results from a qualifying duty accident and the Medical Board approves the claim.Key facts
- 10 years of credited service are generally required for Tier VI ordinary disability retirement.
- 33⅓% of FAS is the minimum ordinary-disability formula before comparing the service-based amount.
- 66⅔% of FAS is the Tier VI accident-disability pension formula stated in the current SPD.
Ordinary disability starts with a 10-year service gate
NYC TRS says a Tier VI member may qualify for ordinary disability retirement when the member is in service or on an official leave of absence, becomes physically or mentally incapable of performing work duties, and has at least 10 years of credited service. That is different from normal retirement vesting, which is only five years. A member can therefore be vested for a future service retirement and still be short of the separate 10-year threshold required for ordinary disability retirement.
The current Tier VI Summary Plan Description states that an approved ordinary disability allowance is the greater of one-third of Final Average Salary or one-sixtieth of FAS multiplied by years of service credit. If the member is also eligible for a service retirement and that service-retirement allowance is larger, the SPD says the larger service benefit is payable. The result is not a generic “disability percentage”; TRS compares the formulas that apply to the member’s record.
Accident disability focuses on causation, not 10 years of service
Accident disability uses a different eligibility test. NYC TRS requires incapacity to result naturally and proximately from an accident sustained in the performance of duties in active service, without the member’s own willful negligence. The ordinary 10-year service requirement is not the controlling gate for a qualifying duty accident. The Tier VI SPD states that an accident disability pension equals two-thirds of FAS, with an additional annuity based on an ASAF balance when applicable.
That distinction makes evidence of the event critical. The Tier VI Accident Disability Retirement Application, code AD6, requires an employer accident report, physician information, medical records, and the member’s own accident-and-disability report. The form says TRS considers the application complete only when the required components are received. A diagnosis alone does not establish the accident branch; the Medical Board must determine both incapacity and the required connection between the accident and the disability.
Filing timing can decide whether the accident claim is heard
The AD6 instructions impose specific filing windows. A Tier VI member generally files while in active service or within three months after the last date on active payroll. If the member was on leave without pay for medical reasons, the application may be filed within 12 months after notice of termination. Those are not informal planning targets; they are part of the application instructions and can matter before the Medical Board ever reaches the medical merits.
After a complete application is received, TRS schedules review by its Medical Board. The accident application states that the Medical Board determines eligibility and that TRS notifies the member of the decision. If an application is denied, TRS’ FAQ describes review options, including a Special Medical Committee request within the stated period or other legal review routes. Because filing deadlines and appeal choices are consequential, members should use the current forms rather than an old saved PDF.
Compare ordinary and accident disability before choosing a filing path
The two disability routes answer different questions. Ordinary disability asks whether a Tier VI member with at least 10 years of credit is physically or mentally incapable of performing work duties. Accident disability asks whether the incapacity is the natural and proximate result of a duty accident that was not caused by willful negligence. A member with 12 years of service and a non-work medical condition may fit the ordinary branch; a member with fewer years may still fit the accident branch if the statutory accident standard is met.
The benefit formulas are also different. The Tier VI SPD gives ordinary disability as the greater of one-third of FAS or one-sixtieth of FAS for each year of credited service. Accident disability is two-thirds of FAS. For example, 20 years under the one-sixtieth formula equals one-third of FAS, so the two ordinary formulas meet at that point. The actual benefit can also include an ASAF annuity and can be affected by other plan-specific facts.
| Path | Service threshold | Published pension formula |
|---|---|---|
| Ordinary disability | 10 years generally | Greater of 1/3 FAS or 1/60 × FAS × service |
| Accident disability | 10-year threshold not controlling for qualifying duty accident | 2/3 of FAS |
| Lump-sum disability | Separate medical eligibility | Amount tied to death benefit under the applicable rule |
Treat the AD6 filing packet as an evidence checklist
The AD6 instructions are unusually useful because they show what turns a medical problem into a complete accident-disability filing. TRS lists the application itself, physician report, employer accident report, medical records, personal report of accident and disability, and an authorization for release of health information. An incomplete application can be archived after the period described in the form. Members should therefore build the record around the work event and resulting incapacity rather than sending isolated medical documents with no causation narrative.
The timing rules should be placed on the same checklist. Filing while on active payroll is the cleanest route, but AD6 also identifies the three-month post-payroll window and the 12-month window for certain medical leaves that end in termination. Someone waiting for a workers’ compensation case, surgery, or long diagnostic process should not assume those other proceedings pause the TRS filing clock. The current TRS form controls the administrative deadline for the pension application.
Understand what happens after Medical Board approval or denial
Approval is not simply a payment calculation. The Medical Board determines disability eligibility, and the SPD explains that the benefit continues for life unless the member returns to active service or, where applicable, refuses required re-examination. Disability retirees may face a different employment analysis from service retirees, which is why Section 211 and 212 waivers are not available to them under TRS’ retiree FAQ. A person planning any return to work should coordinate the employment decision with the disability status.
If the Medical Board denies the application, NYC TRS describes multiple paths, including a Special Medical Committee review under conditions stated by the system and judicial review through an Article 78 proceeding. Those choices can affect later rights, so a member should read the current denial notice before electing a review route. This guide can explain the published process, but it cannot determine which appeal route is appropriate for a specific medical or legal record.
Before you make a decision
- Confirm whether the condition is ordinary disability or tied to a specific duty accident.
- Count credited service separately from the five-year vesting threshold.
- Download the current OD6 or AD6 form rather than using an old saved copy.
- Build the medical and accident record before the applicable filing window closes.
- Read the Medical Board decision and review rights before choosing any appeal route.
Frequently asked questions
How many years do I need for NYC TRS Tier VI ordinary disability retirement?
NYC TRS states that Tier VI members generally need at least 10 years of credited service for ordinary disability retirement, in addition to being in service or on an official leave and being physically or mentally incapable of performing their work duties.
Does NYC TRS accident disability require 10 years of service?
A qualifying accident disability claim uses a different standard. The member must be incapacitated as the natural and proximate result of an accident sustained in the performance of duty without willful negligence. The ordinary 10-year service threshold is not the controlling requirement for that duty-accident branch.
How much is a Tier VI ordinary disability pension?
The Tier VI Summary Plan Description states that ordinary disability equals the greater of one-third of Final Average Salary or one-sixtieth of FAS multiplied by years of credited service. If an eligible service-retirement allowance is larger, the SPD says the larger service benefit is payable.
