Uttarakhand GST rules set procedures for composition levy, registration, migration, cancellation and online electronic authentication forms. The Rules implement the Uttarakhand GST Act by prescribing electronic procedures for the composition levy (intimation, stock declaration, eligibility, rates and withdrawal), and a detailed online registration framework requiring PAN, mobile and email verification, time bound verification by proper officers, provisional migration enrolment, issuance of GSTIN/registration certificates, amendment, cancellation and revocation processes, physical verification protocols, and mandated electronic authentication of submissions and notices.
