(a) The board may set and charge annually a fee for the renewal of a license and set the renewal fee for license holders not practicing in the State or for those inactive at a lower fee than for those practicing in the State. The board may waive the renewal fee for all licensees who are serving on active duty in the Armed Services of the United States at the time the fee is due.

(b) If the license renewal fee is not paid by the first of July of each year, or within sixty days from the mailing of notice by the board, whichever is later, the license shall automatically expire and be forfeited. Such license can only be reinstated upon payment of all sums due, and the board may assess such delinquent holder an additional sum not to exceed twenty-five percent of the amount due as a penalty.
