You can amend your tax return by filing FOrm 1040X.
For hurrican damage, you can claim casualty loss deduction. The casualty loss deduction is measured in terms of the economic decline in the value of the property, as a result of the casualty event, with your adjusted cost basis as a maximum deduction ceiling: that is, the fair market value of the property immediately before the casualty less the fair market value of the property immediately after the casualty reduced for any insurance or other reimbursements, but no more than its your adjusted cost basis. You must then reduce the loss by $100 and also reduce the total of your casualty losses by 10 percent of your adjusted gross income for the tax year in which the loss occurred. Only the excess over these $100 and 10 percent limits is deductible.
Taxes on vehicle:
If you are referring to sales tax
paid on purchase of vehicle, than you can add the sales tax to the sales tax deduction that you have calculated from the IRS tables and claim it on Sch A.
If the taxes are personal property taxes, than you might want to check if the taxes are based on the value of the vehicle and imposed by the State/local
Govt and are not the annual tag/license fees ......
