As part of changes to U.S. law beginning in January 2022, Poshmark is required to provide any seller with $600 or more in gross sales for the 2022 calendar year with a Form 1099-K. Once you hit a $600 sales threshold, you will need to provide this information. Order processing will be halted until this is completed.
To add this information in app: please go to My Seller Tools > Manage Taxpayer Information. On web, this is accessed through Account Settings: https://poshmark.com/user/manage_tax_info. If you are an international seller without a U.S. Tax ID, please contact Enterprise Operations for more information on how to proceed.
