The National Technical Information Service (NTIS) sells a 2012 Tax form cd from the IRS for $30. This same information is available free if you use the online 2012 Tax Map. It’s a useful tool that helps you locate tax forms and publications by subject instead of by form number. The Tax Map index is arranged alphabetically. If you want tax forms or publications about investments click on the “I” for a listing. Some forms and publications forms are shown form informational purposes and may not be used when filing taxes. These forms carry notices on them when they are listed only for informational purposes but may not be used when filing taxes.
