Deduction under section 80-IE: schedule amended to add Sikkim, with entries for two undertakings and aggregate deduction. Corrigendum substitutes Schedule 80-IE to insert a new 'ah' entry for Sikkim, adding two undertaking entries for Sikkim each referencing the 30 field of Form 10CCB, and updates the aggregated total deduction for North East undertakings to include these entries, thereby revising the total deduction under the section.
