# When I try to push an e-Invoice to the IRP, I receive an error message indicating that the recipient’s tax treatment is not applicable. How do I resolve this issue?

This error occurs when the GST treatment associated with your customer in Zoho Books does not match their GST treatment in the IRP.

To resolve this issue, you must verify the GST treatment of you customer. Here’s how:

*   Go to _Sales_ on the left sidebar and select **Customers**.
*   Select the customer and click **Edit**.
*   Click **Get Taxpayer Details** next to the _GSTIN / UIN_ field.

In the _Get Taxpayer Details_ page, you can view your customer’s GST treatment as configured in the IRP.

Ensure that the GST treatment in the IRP matches the one in Zoho Books. If there is a mismatch, you should edit the GST treatment of the customer in Zoho Books to match the IRP.

To edit your customer’s GST treatment:

*   Go to _Sales_ on the left sidebar and select **Invoices**.
*   Select the invoice with which you encountered the error and click **Edit**.
*   Change the **GST Treatment** of the customer.
*   Click **Save**.

Now, you will be able to push the invoice to IRP.
