# Exemption override

**Element type: Suggestion**

**Endpoints/models used:** [CreateTransactionModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/CreateTransactionModel/), [LineItemModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/LineItemModel/)

If your application allows for exemption overrides at the line level, then your UI should give users the ability to also identify an entire transaction or individual line items on a transaction as taxable for an otherwise exempt customer.

As an example, consider a carpet installation company that orders carpeting materials and carpet installation tools from a distributor. The carpet installation company was already set up as a reseller in AvaTax, so all of its items are not taxed by default. However, on this invoice, the carpeting is intended for resale and is thus not taxable in this jurisdiction, while the tools are not intended for resale and are taxable. To override the exemption on a line item, pass the keyword`TAXABLE` in the`entityUseCode` field.
