What is the difference between Tier 3 and Tier 4 NYS retirement?

Under Tier 4, you would receive 1 ½% for each additional service year beyond 30. If you retire before age 62 with less than 30 years of service, the pension factor is reduced based on your age. If you are a Tier 3 member, you may retire under either Tier 3 or 4.
