# Deleting LF-Tag expressions
<a name="TBAC-deleting-expressions"></a>

You can delete LF-Tag expressions that are no longer in use. If you have granted permissions to principals on Data Catalog resources using the LF-Tag expression, they will no longer have the permissions.

Only data lake administrators, the LF-Tag expression creator, or a principal with `Drop` permission on the LF-Tag expression can delete an LF-Tag expression. In addition to the `Drop` permission, the principal also needs `lakeformation:DeleteLFTagExpression` IAM permission to delete an LF-Tag expression.

You can delete an LF-Tag expression by using the AWS Lake Formation console, the API, or the AWS Command Line Interface (AWS CLI).

------
#### [ Console ]

**To delete an LF-Tag expression (console)**

1. Open the Lake Formation console at [https://console.aws.amazon.com/lakeformation/](https://console.aws.amazon.com/lakeformation/).

   Sign in as a data lake administrator, the LF-Tag expression creator, or a principal that has permissions to delete the expression.

1. In the navigation pane, under **Permissions**, choose **LF-Tags and permissions**.

1. Choose the **LF-Tag expression** tab.

1. On the **LF-Tag expressions** section, select an LF-Tag expression, and then choose **Delete**.

1. In the **Delete LF-Tag expression?** dialog box, to confirm the deletion, enter the LF-Tag expression name in the designated field and then choose **Delete**.

------
#### [ AWS CLI ]

**To delete an LF-Tag (AWS CLI)**
+ Enter a `delete-lf-tag-expression` command. Provide the expression name and catalog ID to delete.  
**Example**  

  The following example deletes the LF-Tag expression with the name `my-tag-expression` from the Data Catalog with ID `123456789012`. The `catalog-id` parameter is optional if you're using the same account as your AWS CLI configuration. After deleting an LF-Tag expression, Lake Formation cleans up the associated permission records for that expression. This includes both individual permission records and aggregate permission records that contain the deleted expression.

  ```
  aws lakeformation delete-lf-tag-expression \
  --name "my-tag-expression" \
  --catalog-id "123456789012"
  ```
