Introduction

Registration is one of the most important compliances under the Goods and Services Tax (GST) regime. It enables a taxpayer to legally collect GST, claim Input Tax Credit (ITC), and comply with GST regulations. This article provides a comprehensive overview of GST registration, amendment procedures, cancellation, suspension, revocation, and other important provisions.


    1. When is GST Registration Required?

    A person liable for GST registration must generally apply within 30 days from the date on which they become liable to register under GST.

    Special Cases: Casual Taxable Person (CTP) and Non-Resident Taxable Person (NRTP)

    Application Timeline

    A Casual Taxable Person or Non-Resident Taxable Person must apply for registration at least 5 days before commencing business activities.

    Validity of Registration

    The registration remains valid for:

    • 90 days initially, and
    • Can be extended by another 90 days.

    However, the validity cannot exceed the period specified in the registration application.

    Advance Tax Deposit

    Such persons may deposit their estimated net GST liability while applying for registration. The deposited amount is credited to their Electronic Cash Ledger.

    If an extension is sought, advance tax for the extended period must also be deposited.

     

    2. Registration Discovered During Investigation

    If during a survey, inspection, search, inquiry, or investigation it is found that a person was required to obtain GST registration but failed to do so:

    • The officer may grant temporary registration.
    • Registration becomes effective from the date of the officer's order.
    • Penalties and other consequences may also apply.

    The person must apply for regular registration within:

    • 90 days from temporary registration, or
    • 30 days from the appellate order if an appeal is filed.

     

    3. Place and Number of Registrations

    1. State-wise Registration - GST registration is required in every State or Union Territory from where taxable supplies are made.
    2. Supplies from Territorial Waters - Persons making supplies from India's territorial waters must obtain registration in the nearest State or Union Territory.

    Number of Registrations

    1. One State, One Registration - Normally, a taxpayer obtains one registration in a State or Union Territory.
    2. One State, Multiple Registrations - Separate registrations may be obtained for different places of business within the same State or Union Territory.
    3. Multiple States, Single Registration - Certain specified persons such as UIN holders, embassies, UN bodies, and specified suppliers located outside India may be allowed a single registration valid across India.
