Changes to the age band premiums for small group insurance (1-100 employees) will begin to take effect in 2018, at your renewal. Presently, insurers assign a single banded premium rate for all individuals ages 0-20, with individual age rates starting at age 21 upward (to age 63). Under the new rating system, effective January 1, insurance carriers updated the one banded premium rate to ages 0-14 and will now assign a single rate to each year of age as early as age 15. As a result, employers will begin to see a premium increase for those that include dependent coverage.
