"Revenue Procedure 2010-36 provides the following relief:
- Individuals who pay to repair damage to their personal residences or household appliances resulting from corrosive drywall may treat the amount paid as a casualty loss in the year of payment.
- Taxpayers who have already filed their income tax return for the year of payment generally have three years to file an amended return and claim the deduction.The amount of a loss that may be claimed depends on whether the taxpayer has a pending claim for reimbursement (or intends to pursue reimbursement) of the loss through property insurance, litigation or otherwise.
- In cases where a taxpayer does not have a pending claim for reimbursement, the taxpayer may claim as a loss all unreimbursed amounts paid during the taxable year to repair damage to the taxpayer’s personal residence and household appliances resulting from corrosive drywall.
- If a taxpayer does have a pending claim (or intends to pursue reimbursement), a taxpayer may claim a loss for 75 percent of the unreimbursed amount paid during the taxable year to repair damage to the taxpayer’s personal residence and household appliances that resulted from corrosive drywall.
For purposes of this revenue procedure, the term “corrosive drywall” means drywall that is identified as problem drywall under the two step identification method published by the CPSC and the Department of Housing and Urban Development in their interim guidance dated January 28, 2010."
