The IRS announced late this afternoon that filing deadlines for corporate taxes and estimated taxes due September 15th have been extended at least one week in impacted areas. The IRS announcement notes, “Affected taxpayers can mark paper tax returns with the words “Hurricane Ike.” Taxpayers who e-file their returns can use their software’s “disaster” feature, if available.” Although not specifically mentioned in the IRS notice, I assume this covers taxpayers in the Gulf Coast sections of Texas and Western Louisiana.
