Deemed registration under GST rules may result in automatic approval when authorities fail to act, affecting registration status. Deemed registration treats a registration or Unique Identity Number granted under a State or Union Territory GST Act as effective under the central Act unless the application is rejected within the time prescribed under the central law; rejections under State/UT law are reciprocally deemed rejections under the central Act. Rule 9(5) provides that an application is deemed approved where the proper officer fails to act within prescribed working-day timelines after submission or after receipt of required clarifications, subject to subsequent verification procedures and SOPs for taxpayers granted deemed registration.
