<prompt> Human: Hi. For the past year, I have completed several surveys with an online company that pays participants in Amazon gift cards for taking part in user interviews for various companies if they match the criteria. And it has been good. I earned like 400 or more worth of Amazon Gift card over the year. Now, all of a sudden they are requesting a W-9 form from me again and again via a third party over emails. Am I under any obligation to submit it through them, or this is something I can refuse to do.  <response>: You can refuse, and they can deactivate your account. Even though youre getting paid in gift cards, I believe you would still need to declare it on your taxes.
