Good Evening @Seller_kJtdzwFfwSudN,

I am assuming your question around tax identity is for the US Tax Interview process? I am providing a few Seller Central help pages below around the Tax Interview process:

The information provided on this page does not constitute tax, legal, or other professional advice and must not be used as such. You should consult your professional tax advisor if you have questions about your personal tax obligation.

• U.S. Tax Interview FAQ
• U.S. Income Reporting & Tax Identity Collection FAQ
• Do i really need an ITIN? (Thread on the forums from a few months ago)

Please let us know on this discussion if you require additional assistance or you can always contact Selling Partner Support with inquiries at anytime. Have a great rest of the week! ~ Cooper_Amazon
