Application of Income-tax Act to 'person' under Chapter XII-BA expands scope so all provisions apply unless expressly excluded. The amendment substitutes the phrase 'a limited liability partnership' with 'a person' in the provision, so that, except as saved in Chapter XII-BA, all other provisions of the Income-tax Act shall apply to the person referred to in that Chapter, and the change is given effect from the date specified for ensuing assessment years.
