Just got an email from PayPal (looks legit) that they want my tax ID number. They need it to send tax statements to me and the IRS if my PayPal transactions exceed $20,000 and 200 in number in one year. Well, I have never made anywhere near $20,000 from ebay sales in a year! I don't have a tax ID number because I don't have a business. Do I just ignore them?
