# General ledger classifications improvements in items

When you create or update an item, you can now set the `percentage` field as the item tax percentage. You can set this field for a set of item `type` values.

* `DISCOUNT`
* `SALES_TAX`
* `OTHER_CHARGE`

See [POST /v3/classifications/items](https://developer.bill.com/reference/createclassificationitem) in the API reference for more information.
