Section 6405 requires that a report be made to the Joint Committee on Taxation of proposed refunds or credits in excess of $100,000 of any income tax (including any qualified State individual income tax collected by the Federal Government), war profits tax, excess profits tax, estate tax, or gift tax. An exception is provided under which refunds and credits made after July 1, 1972, and attributable to an election under section 165(h) to deduct a disaster loss for the taxable year in which the disaster occurred, may be made prior to the submission of such report to the Joint Committee on Taxation.
