WASHINGTON (AP) — The Internal Revenue Service is extending tax payment deadlines for some individuals and businesses affected by Hurricane Irene.The tax agency says the extensions will initially apply to taxpayers in certain counties in North Carolina, New Jersey, New York and Puerto Rico. It says the list of eligible taxpayers is expected to grow as the Federal Emergency Management Agency makes further damage assessments.The tax relief allows businesses that had previously obtained extensions until Sept. 15 to file 2010 returns to wait until Oct. 31. Also given extensions until Oct. 31 are individuals and businesses required to file 2010 returns by Oct. 17 and those who normally would make third-quarter estimated tax payments by Sept. 15.
