Add Tobacco and Vape Excise Taxes at Checkout on Shopify

What merchants get wrong

Federal and state excise taxes layer on top of each other—you need to account for both. Vaping tax structure varies wildly by state: some charge per milliliter of liquid, others by percentage of wholesale or retail price, and some states have no vaping-specific tax yet. The fee must apply only to tobacco and vaping products, which means conditional product targeting is essential. PACT Act restrictions also affect how you can ship these products. Merchants often assume one rate applies everywhere; in reality, you need destination-state logic.
