2014 IFTA / IRP AUDIT WORKSHOP Note: Although states don't want to see double miles, the miles by state has to be shown somewhere on the return or you lose a step in the calculation and preparers get confused. The calculation to allocate taxable distance could be made on a schedule separate from the return.
