what is the official website for the irs?
- The Official Internal Revenue Service Web Site Is IRS.gov. Millions of taxpayers this filing season will go online to retrieve tax forms, publications and other information from the Internal Revenue Service. Unfortunately, some of them will end up at Web sites that have no affiliation with the IRS. The official Web site for the Internal Revenue Service is IRS.gov, and all IRS.gov Web page addresses begin with http://www.irs.gov. There are many phony Internet sites that impersonate federal or state tax agency sites.
