One-time tax option for promoters to elect construction tax rate; failure to file annexure triggers default reduced tax treatment. Promoters must submit the one-time option Form (Annexure-IV to Notification No. 3/2019 State Tax (Rate)) to the Jurisdictional Joint Commissioner to elect payment of tax on construction of apartments at the rates prescribed for item (ie) or item (if) against serial number 3 of the Table in Notification No. 11/2017; failure to submit the Form will result in the promoter being deemed to accept the alternative reduced tax treatment prescribed in Notification No. 3/2019.
