Don't give your SSN to E-bay! We even don't know who they are because they hide their fax number, address and other information from us! They are going to use your personal data tor their own profit or, to resell to third parties. One day you may find yourself homeless because someone who has your SSN and Birthdate sold your home for you! The IRS does not require to report any sales for used items and, you do not have to file the taxes for any amounts under 4,500 regardless of income source: wages, unemployment, etc. When I make less than this amount, my son reports me as a dependent on his taxes to get refund from IRS.
