 ## What are Tax Rates?
 
-A tax rate is a percentage amount used to calculate the tax amount for each taxable item’s price, such as line items or shipping methods, in a cart. The sum of all calculated tax amounts are then added to the cart’s total as a tax total.
+A tax rate, represented by the [TaxRate data model](https://docs.medusajs.com/references/tax/models/TaxRate/index.html.md), is a percentage amount used to calculate the tax amount for each taxable item’s price, such as line items or shipping methods, in a cart. The sum of all calculated tax amounts are then added to the cart’s total as a tax total.
