There seems to be a run on W8BEN requests being sent out to affiliates lately from more companies than usual. This includes being sent to affiliates outside the U.S. This has gotten so tiresome I now send out a form letter in response. All companies except one have backed off once I explained that anyone outside the U.S. with non U.S.-sourced income are not required to fill out any U.S. tax forms, quoting the Google Adsense page on this subject. Two of them are even making arrangements to automate an online form for non-U.S. affiliates to expedite their process. ie. a simple declaration that U.S. tax laws do not apply to their situation.
However, Esellerate has stuck to their guns on this. They made it clear I would not be paid unless I sent in the required W8BEN. I am not going to send personal information that they have no legal right or reason to have on file. But, in order to hold my position on this I had to say good-bye to any earnings still owing to me. That was $67.51. I had no time to make the $100 minimum to be paid in December since they only emailed out this 'new arrangement' on November 28th and subsquently ignored all my emails back to them about it until mid-January. The new rules went into effect on January 1st. Although I made several appeals, the manager of the accounting department was in no way willing to look into the situation or discuss it. Boom, account closed. Money gone.
Unless you're also willing to hand over ultra-personal information to Esellerate, without any legal requirement to do so, you can also kiss your earnings good-bye.
