Stripe may be required to collect various tax documents from you. Stripe has various US tax reporting requirements both to account holders and to the US Internal Revenue Service ("IRS"). The main reporting requirement that Stripe has is based on payment processing.
For US Direct and Standard account holders, Stripe must report the respective payment volume that they have processed for its account holders on a form 1099-K, assuming that reporting thresholds are met. Non-US account holders however are not subject to 1099-K tax reporting. In order to establish if an account holder is a US person or a non-US person, Stripe will ask for certain identifying information and a certification from the account holder. This information is generally collected on a form W-9 for US account holder or a form W-8 for non-US account holders. We may also collect supplementary support forms, like a form 4669 or an Affidavit of Unchanged Status, depending on the situation.
This article is neither legal advice nor tax advice. We recommend that you speak to your solicitor or accounting firm if you have any questions or concerns related to tax reporting.
