Exemptions from tax collection at lower rate enable government notifications and require collectors to report affected receipts. Section 206C(12) empowers the Central Government by notification to specify persons or classes for whom no collection of tax or collection at a lower rate shall apply in respect of specified transactions, notwithstanding other provisions. Rule 31AA(4)(viii) requires the collector, when preparing statements of tax collected, to furnish particulars of amounts received or debited on which tax was not collected or was collected at a lower rate pursuant to any notification under Section 206C(12).
