The IRS can authorize tax relief for areas that are affected by major disasters. Generally, this is authorized to areas that are identified by FEMA to have at least one area that qualifies for their Individual Assistance Program.
To see tax relief for the current tax year, you can visit the IRS website: Tax Relief in Disaster Situations. You may also find state disaster information from the IRS website: IRS News From Around the Nation. If you were in an area that was affected by a Federally declared disaster, you can find more information on how to report it on your taxes here.
