Preserve advance releases and the authoritative Internal Revenue Bulletin rendition; directory timestamps are file-publication metadata, not legal effective dates. HTML bulletins begin June 2003; earlier available issues require full PDF parsing.
This collection currently includes the publisher’s available advance-release directory. Historical bulletin renditions are discovered separately; an advance-release record alone does not certify the collection archive complete.
# Extended Time for Use of the Revised Form W-9 ## Announcement 2001-15 Purpose This is to advise persons required to file information returns of the availability and required use of Form W-9, Request for Taxpayer Identification Number and Certification (Rev. December, 2000). In response to payor concerns about implementing the new certification requirements, the use of revised Form W-9 is optional until July 1, 2001. Certification of U.S. Status The major change to the form is that under Part III, Certification, a payee must now certify that he or she is a U.S. person (including a U.S. resident alien). Payors must use the revised Form W-9 for all new solicitations after June 30, 2001. Foreign Payees A foreign person may not use Form W-9 to furnish his or her taxpayer identification number to the payor after December 31, 2000. Instead, foreign payees must use the appropriate Form W-8.
