Why Excise, Tariffs & Duties Tax Manager?

Add excise, tariffs, duties and custom per-product fees to your BigCommerce checkout, with no custom code. Set your own rules, or connect Avalara AvaTax / AvaTax Excise and TaxJar. The app calculates the tax at cart and checkout, then carries it through to the order.

Rules that fit how you sell

• Custom taxes, duties, levies and per-product flat rates

• Base rates on SKU, product category, tax class or customer group

• Limit rules by shipping zone, ZIP/postal code, or minimum cart value

• "Tax-on-tax" logic, e.g., duties that themselves incur excise

• Tax by weight or volume, and apply rules to shipping when needed

• Mix and match rate bands, ideal for alcohol, tobacco and luxury goods

B2B and tax-exempt customers

• Exemption codes: set a code on the BigCommerce customer account and the app applies the matching rules automatically

• Wholesale, government, non-profit and other exemptions, handled without manual order edits

Clear at checkout

• Itemized taxes: each tax appears as its own named line, so shoppers see Excise, Duty or Tariff amounts separately rather than one lump sum

• Works with BigCommerce tax: runs alongside built-in tax rates, or overrides them when your conditions match

• Channel control: restrict the app to specific storefront channels

Manage taxes in bulk

• Export and import your tax rules as CSV

• Update existing rules, or replace all in one step
