About the Mill Assessment

California assesses a fee on all pesticide sales at the point of first sale into the state. A "mill" is equal to one-tenth of a cent. This assessment is 21 mills, or 2.1 cents per dollar of sales. Revenues support the state’s pesticide regulatory program. The mill assessment program is a self-assessment system. Each quarter, DPR mails reporting forms to pesticide registrants, licensed pest control dealers, and licensed pesticide brokers. Completed forms are due to DPR within 30 days of the end of the quarter.

Pesticide registrants, pest control dealers, and pesticide brokers who first sell a pesticide into or within California must report sales and pay mill assessment fees.
