NYC TRS Retirement Contribution Rates: The 3% and 4.85% Rules by Tier

Your Paycheck Deduction Is Not One-Size-Fits-All

Every NYC TRS member has mandatory QPP contributions deducted from their paycheck, but the percentage varies by tier, program enrollment, and — for Tier VI — salary level. Getting the rate wrong doesn't just affect your take-home pay projections. It also determines the cost of service credit buybacks and deficit payoffs, both of which must be resolved before your retirement date.

Tier IV Basic Plan: 3% Until You Hit 10 Years

Tier IV members on the Basic Plan contribute 3% of gross compensation to the Member Contributions Accumulation Fund (MCAF). Once you accumulate 10 years of credited service, mandatory contributions stop entirely. Your paycheck deduction drops to zero, but your service credit keeps accruing for pension calculation purposes.

If you have a contribution deficit in your MCAF — from unpaid leave, a late start, or a gap in service — the outstanding amount must be paid before your effective retirement date. Leaving a deficit unresolved triggers an actuarial reduction to your monthly pension. TRS will calculate the reduction automatically, and it's permanent.

Tier IV 55/25 and 55/27 Programs: The 4.85% Rate

Members enrolled in the Age 55 programs pay a higher rate: 4.85% of gross compensation. This breaks down as the standard 3% base contribution plus an additional 1.85% program surcharge.

The rate has a phase-down. For 55/25 members, it drops from 4.85% to 1.85% once you reach 25 years of credited service. For 55/27 members, it drops to 1.85% at 27 years.

This matters for buyback calculations. If you are purchasing prior service credit under a 55/25 or 55/27 membership, TRS prices it at 4.85% of the wages earned during that period, not 3%. Military service credit under USERRA or NYS Military Law is calculated the same way: 3% of compensation earned during the military period, plus 1.85% for Age 55 Program enrollees.

Tier VI: A Sliding Scale Based on Salary

Tier VI contribution rates range from 3% to 6% depending on your annual gross salary. As your salary grows through step increases, longevity differentials, or per-session work, your applicable rate may shift within that range. Check MyTRS for the rate currently applied to your salary.

This sliding scale also applies to buyback calculations. A Tier VI member purchasing prior service credit pays 6% of wages earned during that period regardless of their salary bracket at the time of the buyback, plus accumulated interest.

What Happens to Your Contributions at Retirement

Your QPP is a defined-benefit plan, and the retirement allowance formula uses your Final Average Salary and total service credit. Outstanding MCAF deficits must be paid before your effective retirement date; an unpaid deficit results in an actuarial reduction to your monthly benefit.

Tier IV and Tier VI pension vesting requires five years of total service credit. Ask TRS about contribution refunds and their effect on your service credit and pension rights before requesting one.

Checking Your Contribution History

Log into MyTRS and review your Annual Benefits Statement for total service credit. If there is a gap between what you expected and what appears — common for members who transferred from CUNY, took extended leaves, or worked per-session alongside a full-time appointment — schedule a counseling session with TRS Member Services to audit the discrepancy. Ask the counselor to review any MCAF deficit payoff amount before you file.
