Recipients are required to submit tax information before receiving payments. This is collected during onboarding and kept on file for future payments.

​
What’s required

U.S. recipients: W-9 form and Taxpayer Identification Number (TIN) International recipients: W-8 form and country-specific tax details

​
How it works

During onboarding, you’ll enter your information and electronically sign your tax form. Karat then verifies your details, which may include identity checks, sanctions screening, and TIN matching for U.S. users. Payments may be delayed if your tax information is incomplete or incorrect. Tax forms are updated automatically if your information changes.

​
Receiving payments from multiple payers

If you’ve been invited to receive payments from more than one organization, each payer that requires tax information collects it separately. Submitting your tax form for one payer doesn’t automatically share it with another. When you accept a new payment invitation, you may be prompted to complete your tax form again for that payer, even if you’ve already finished the process before. Your previously approved details are reused where possible, so you typically only need to review and re-sign.
