What is the exemption of property and income of a State from Union taxation?
The property and income of a State shall be exempt from Union taxation. However, this does not prevent the Union from imposing, or authorizing the imposition of, any tax to the extent that Parliament may by law provide in respect of a trade or business of any kind carried on by, or on behalf of, the Government of a State, or any operations connected therewith, or any property used or occupied for the purposes of such trade or business, or any income accruing or arising in connection therewith.
