# Override group

Learn about override groups, their creation, and usage in the AFC Customer Portal.

An override is used to modify tax rates for a specified jurisdiction, alter the tax logic (how or when the tax is applied) for a Transaction/Service pair, and add or remove taxes from a Transaction/Service pair. In AFC, you can assign these overrides to a group.

Note

Before adding an override group, be sure that Avalara has migrated your customization into the Customer Portal. Contact your Customer Account Manager (CAM) for more details.

**Creating an override group**:

Override groups are created through the AFC Customer Portal in Home > Settings > Manage customizations > Overrides. The override group must be applied to a profile to be used.

**Using an override group**:

The Override group is applied to a client profile. Pass the associated `client_profile_id` as part of the header to use the Override group. No additional options need to be included in the transaction for the Override to be applied. Simply run a transaction with the applicable `client_profile_id`. Remove any instances of the Tax Override object (`ovr`) that may be included in the transaction.
