[Back](./) # How do I associate the Taxes to the contacts in Zoho Books that come from Zoho CRM? The tax associated with a record in Zoho CRM will not get synced into Zoho Books via the integration. Instead, you can make use of a [custom function](https://www.zoho.com/books/help/settings/automation.html#custom-functions). * Create a custom field for the **Contacts/Accounts** module in Zoho CRM and give the tax value. * Configure a Custom function in such a way that the value from the custom field in CRM updates the **Tax field** in Zoho Books. For further assistance, you can write to us at [support@zohocrm.com](mailto:support@zohocrm.com). * * *
