Plastic Bag Regulations. Beginning January 1, 2026, the pass-through charge for reusable carryout plastic film bags is $0.12. A retail establishment is prohibited from reimbursing a customer any portion of the pass-through charge.
Beginning January 1, 2028, reusable plastic film bags must be at least four mils in thickness. Until December 31, 2027, retail establishments that offer for sale reusable plastic bags with a thickness of at least four mils must collect a $0.40 penalty in addition to the $0.12 pass-through charge. This $0.40 penalty must be deposited in the Waste Reduction, Recycling, and Litter Control Account, and, like the $0.12 pass-through charge, must be shown on receipts provided to customers.
Retail establishments may not collect a pass-through charge from a person using a voucher or electronic benefits card issued under Women, Infants and Children (WIC), the Supplemental Nutrition Assistance Program, Temporary Assistance for Needy Families, or the State Food Assistance Program. The pass-through charge is a taxable retail sale and must be shown as such on a receipt provided to customers. Retail establishments may deduct from business and occupation taxes the amounts collected from pass-through charges. This tax deduction is not subject to the tax preference performance statement or automatic expiration date.
Report on Carryout Bag Regulations. The Department of Commerce, in consultation with the Department of Ecology, was required to submit a report to the Legislature by December 31, 2024, addressing the effectiveness of the pass-through charge for carryout bags, the availability and pricing of various types of carryout bags, and the sufficiency of the pass-through charge relative to the cost of authorized bags to retail establishments and making recommendations for revisions to carryout bag requirements.
A report authored by Washington State University was submitted to the Legislature in November of 2025. The report found that between 2021 and 2022, the number of plastic bags distributed decreased by an estimated 50 percent while the total plastic use by weight increased by an estimated 17 percent. The report contained two recommendations related to the plastic bag thickness requirement and the pass-through charge.
Film plastic and paper carryout bags may be provided to customers at retail establishments if they meet the minimum recycled content standards.
Requirements related to minimum thickness standards for reusable carryout bags made of film plastic are eliminated.
The pass-through charge for paper carryout bags is retained at $0.08 and for film plastic carryout bags is lowered from $0.12 to $0.08.
