Tax exemption is not applied on checkout for customers associated by email

[frankie567]

• A customer [email protected] with a valid tax ID exists on an organization
• They start a new checkout session.
• They put the same email [email protected].
• They leave the Tax ID blank

➡️ Payment is taken with tax included
➡️ On the backend, we associate the checkout and invoice with the existing customer. Thus, Tax ID is applied on the invoice.

🪲 There is a mismatch between the amount paid (tax included) and the expected amount on the invoice.

➡️ After associating the customer, we need to recompute the tax amount before confirming the payment.
