TaxJar API Product Categories

The TaxJar API provides product-level tax rules for a subset of product categories. These categories are to be used for products that are either exempt from sales tax in some jurisdictions or are taxed at reduced rates. You need not pass in a product tax code for sales tax calculations on product that is fully taxable. Simply leave that parameter out.

The categories currently supported by the TaxJar API are shown in this response in our API documentation.

• While we can't advise you regarding which category your products would fall into, if we don’t have a category for your specific item and the item isn't taxed at a special rate, you can leave the product code blank and we will treat the item as fully taxable goods.
• IMPORTANT: It’s absolutely necessary to choose the right product tax category. Using an incorrect PTC may lead to unexpected tax results.
