# Resource: Contact Tax Details

# Type: Contact Tax Details Object

# Link: https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/contact-tax-details/contact-tax-details-object.md

## Description: Contact tax details hold the tax-related information for a single contact, keyed
by the contact's ID. Their main purpose is to associate a contact with a tax
exempt group, so that the contact receives the group's tax exemption
automatically at checkout.

Each contact's tax details map the contact to at most one tax exempt group.
During tax calculation, the buyer's contact ID resolves their tax details, and if
`taxExemptGroupId` is set, the matching exemption is applied and reported as an
exempt amount in the tax breakdown.

Contacts are typically added to a group by a site owner in the dashboard, or by a
VAT-validation app, such as Exemptify, that verifies a customer's VAT ID at
checkout and then associates the contact with the relevant exempt group. Once
associated, later checkouts by the same contact are exempt without re-entering the
VAT ID.
