# General information about US tax form collection for Stripe

Stripe may be required to collect various tax documents from some accounts. Stripe must comply with various U.S. tax reporting requirements both to account holders and to the U.S. Internal Revenue Service (“IRS”).
Per IRS regulations, Stripe may be required to report the respective payment volume processed on a [Form 1099-K](https://stripe.com/questions/1099-k-forms-issued-by-stripe) for all relevant US tax residents. Non-US tax residents are not subject to Form 1099-K tax reporting. In most cases, Stripe relies on the information provided during onboarding to establish if a business is considered a US person or a non-US person.
In limited cases, Stripe is required to collect this tax residency information on a certified tax form. This certified information is generally collected on a [Form W-9](https://www.irs.gov/pub/irs-pdf/fw9.pdf) for US tax residents or a Form W-8 for non-US tax residents. Stripe may also need to collect supplementary support forms like a Form 4669 or an Affidavit of Unchanged Status if applicable.
Non-US accounts that add US bank accounts or US addresses may be asked to complete a Form W-8/W-9 to establish tax residency. Even if added by mistake, Stripe is still required to collect a Form W-8/W-9. To avoid disruption in services, complete this request within 14 days of when notified.
