WASHINGTON – The IRS has extended another deadline to give those affected by Hurricane Katrina more time to file their returns. Individual and business taxpayers in the most severely damaged parishes and counties of Louisiana and Mississippi automatically have through Aug. 28, 2006, to file returns and make certain tax payments that had a due date or extended due date on or after Aug. 29, 2005, and on or before Aug. 28, 2006, the IRS announced on Feb. 17. In addition, the failure to deposit penalty will be waived for taxpayers in these areas who are unable to make their deposits during this time period. The automatic postponement applies to taxpayers in the following Louisiana parishes: Cameron, Jefferson, Orleans, Plaquemines, St. Bernard, St. Charles, and St. Tammany. The postponement also applies automatically to taxpayers in the Mississippi counties of Hancock, Harrison and Jackson. To ensure taxpayers outside the above areas who suffered severe hurricane damage get necessary relief from filing and payment deadlines, these taxpayers must identify themselves as impacted by writing "Hurricane Katrina" in red ink at the top of the return. Individual, corporation, partnership, estate, trust, S-corporation, generation-skipping, employment and certain excise tax returns qualify for the extension. On Feb. 14, IRS extended its deadline to Oct. 16, 2006 for Hurricanes Katrina, Rita or Wilma who wish to claim disaster-related losses on their prior year federal income tax return. The original deadline was April 17.
