Key Takeaways

• Effective date: January 1, 2026
• Tax scope: All products containing nicotine or tobacco

• Tax base change: From volume-based to value-based taxation
• Nicotine-containing e-cigarette products will be subject to the litter tax

2Firsts, December 29, 2025 – According to a notice released by the Washington State Department of Revenue, effective January 1, 2026, any product containing nicotine will be subject to the Tobacco Products Tax, regardless of whether the nicotine is derived from tobacco or synthetically produced. Previously, some nicotine products were subject to the vapor products tax.

The Tobacco Products Tax applies to all products containing tobacco or nicotine, including cigars, pipe tobacco, chewing tobacco, e-cigarettes, synthetic nicotine pouches, nicotine e-cigarette products, and any other products containing tobacco or nicotine in any form. Newly taxed products include synthetic nicotine pouches that were previously untaxed, disposable e-cigarette products, and nicotine-containing e-liquids.

The regulations also clarify that “tobacco products” do not include cigarettes, nor do they include any drug, device, or combination product approved for sale by the U.S. Food and Drug Administration as of December 31, 2024.

The Tobacco Products Tax is calculated based on the taxable selling price of nicotine products. According to reports by NBC Right Now and KOMO News, the tax rate for all nicotine and tobacco products is 95% of the selling price.

Retailers and distributors must report the value of their existing inventory of nicotine products on the first return filed after January 1, 2026. A one-time line item will be added to the return: “Pre-existing inventories of nicotine products as of January 1, 2026.”

If a product is purchased from a non-affiliated seller, the purchase price should be used as the selling price. If the retailer or distributor is affiliated with the manufacturer or distributor, the actual selling price must be used.

The vapor products tax is calculated based on e-liquid volume and container type, while the Tobacco Products Tax is based on the value of the product in its original package or container. When calculating the Tobacco Products Tax on nicotine-containing e-cigarette products, the selling price must be used rather than volume.

In addition, the litter tax applies to all tobacco products. Previously, e-cigarette products were not subject to the litter tax; however, following the implementation of the new rules, nicotine-containing e-cigarette products will be included. No credit will be provided for vapor products tax previously paid.

Businesses that sell tobacco products are required to obtain a tobacco retail endorsement for each sales location, which can be added to their business license through a MyDOR account.
