We need your tax information before we can pay you. You will receive an email from HelloWorks saying Open Collective is requesting you fill out a form. This is required by the IRS (US tax agency) for everyone who invoices $600 or more per year. If you have not received the email within 24 hours, or you have any questions, please contact [email protected] For more info, see our help docs about taxes.

Hello Guillaume. I am not able to find your tax form on file. Sorry if you already sent it—we are still working the bugs out of our system for tracking these forms.


The total amount of the expenses that you have submitted this year to this host exceeds $600. To comply with the IRS, we need you to send us by email one of the following tax forms:

W9 if you are a US person (a US citizen or US resident or a US incorporated entity)

W-8BEN(for individuals) or W-8BEN-E(for companies) who are not a US person.
