Accounting Web has a good article detailing some of the assistance available for tax and accounting woes caused by the hurricanes from both the IRS and the American Institute of Certified Public Accountants. (AICPA)

The IRS, for example, has extended various deadlines, such as that for estimated tax payments normally due Sept. 15, until Oct. 31 and has waived late-filing or late-payment penalties that would otherwise apply. An agency spokesman said the IRS has set up a task force to work out other assistance that might benefit taxpayers in the afflicted areas.
The U.S. Postal Service is focusing on getting Social Security checks to recipients and has set up mobile facilities in Louisiana and Mississippi "for people to be able to come and get their Social Security checks," USPS spokesman Gerry McKiernan said.
The USPS is setting up a "New Orleans" post office at the Astrodome in Houston, where many hurricane refugees have been taken, McKiernan added.
The Social Security Administration is also allowing beneficiaries, many of whom are far from their mailing addresses, to go to any local Social Security office, get their identity verified and receive a check on the spot.
Electronic direct deposit should have been uninterrupted, SSA spokesman Mark Lassiter said, but beneficiaries who are unable to get to their bank or are without their debit card can also get an immediate payment.
I'm glad people are thinking of these things.
