Hi @Jean_Delgado6 That's a great question! Udemy is based in the United States. All companies based in the US have to comply with IRS (Internal Revenue Service) regulations, which includes collecting information about your tax status as an instructor. Furthermore, no matter where you're located, you may have enrolled students from the United States, and those transactions may be subject to US tax.
Once you begin the submission flow at taxforms.udemy.com, you'll see the option to choose whether you are a US or non-US instructor as one of the first selections you make. Depending on what you choose, the platform will guide you through options that are unique to the selection you made as a US or non-US citizen.
In case you have more questions, please reach out to the support team at email@example.com.
