Section 73 - Determination of tax, pertaining to the period up to Financial Year 2023-24, not paid or short paid or erroneously refunded or input tax credit wrongly availed or utilised for any reason other than fraud or any wilful-misstatement or suppression of facts.

Officer must issue show-cause notice for unpaid or wrongly claimed GST tax; penalties avoided by prompt payment

Where a proper officer finds tax unpaid, short paid, erroneously refunded, or input tax credit wrongly availed or utilised for any reason other than fraud or wilful misstatement, the officer must serve a show-cause notice on the taxable person requiring payment of tax, interest and possible penalty; notices must be issued at least three months before the time limit for order. A statement extending issues to related periods may be deemed a notice if based on the same grounds. Voluntary payment before notice or payment within 30 days of notice avoids penalty; otherwise the officer may determine tax, interest and a penalty of 10% of tax or Rs.10,000 (whichever higher) and must order within three years of the annual-return due date or erroneous refund. Provisions apply up to FY 2023-24.
