Beginning at age 62, your pension will be reduced by one-half (50 percent) of the primary Social Security benefit — regardless of whether you are actually collecting a benefit from Social Security. The primary Social Security benefit is the part of your Social Security benefit based on public employment in New York State. It is determined using your wages for service with a public employer for which you received retirement credit. The primary Social Security benefit may not be the same as your actual Social Security benefit. This adjustment applies to both service and disability retirements.
