    This page was written by Patron Accounting’s AI from the official release and reviewed before publishing. It explains the document in plain language. It is not the document itself. Where this page and the original differ, the original governs.

    The short version

    1. A One Person Company is now a separate business type on the form.
    2. Upload proof of your business type, such as an incorporation certificate or partnership deed.
    3. Premises must be declared under standard categories, each with its own documents.
    4. Up to 10 bank account details are now requested when you file.
    5. Company and LLP ID numbers are checked online before the application number is issued.

    In short

    GSTN has issued an advisory that the online GST registration form, FORM GST REG-01, has been revised on the GST portal. It tells people applying for GST registration what new details and documents the form now asks for.

    What has changed

    How it worked before

    The advisory does not describe the earlier form in detail. Several items are described as new or revised, which suggests the earlier form did not ask for them in the same way.

    What has changed

    One Person Company is added as a business type, and you must upload documents that match your business type. Premises are now sorted into standard categories, including owned, rented, consent-based, co-working and SEZ premises, each with its own required documents. The form asks for bank account details, up to 10 accounts, and for the DINs of LLP designated partners. For companies, LLPs and some other entities, the CIN or LLPIN is checked online, and the application number (ARN) is issued only after the checks pass. E-commerce operators and SEZ units or developers also have new sections or fields to fill.

    Who this affects

    Anyone applying for a new GST registration as a company, one person company, LLP, partnership, SEZ unit or SEZ developer, or e-commerce operator.

    An example

    Meera sets up a one person company to sell handmade bags and applies for GST registration. On the revised form she selects One Person Company and uploads its certificate of incorporation. She declares her rented workshop under the rented premises category and uploads the documents the form asks for that category. She lists two bank accounts, which is within the limit of 10, and her application number is issued once her company ID passes the online check.

    What you should do

    Before you apply, read the revised form on the GST portal and gather your incorporation or partnership papers, premises proof and bank details. If your business is an LLP, have the DIN of each designated partner ready. If bank details are not ready when you file, supply them within 30 days of receiving the REG-06 certificate.

    Deadline · Within 30 days from the date of issuance of the registration certificate in FORM GST REG-06, if bank details were not available when you applied

    If you do nothing

    The advisory does not state any penalty for leaving these details out. If details are missing or the company or LLP ID does not validate, the application number is not generated, so your application cannot proceed. If you did not have bank details at filing, the advisory requires you to provide them within 30 days of the REG-06 certificate, and it does not say what follows if that is missed.

    The terms explained

    Does this change apply to me?

    It applies if you are filing a new GST registration application. The advisory covers companies, one person companies, LLPs, partnerships, SEZ units and developers, and e-commerce operators.

    From when do these changes apply?

    The advisory does not give a start date. It says only that the form has already been revised on the GST portal.

    Do I have to file anything now if I already have a GST registration?

    The advisory is aimed at people applying for a new registration. It does not say that existing registrations must be updated.

    What if I do not have my bank details when I apply?

    You can file without them if they are not available, but you must provide them within 30 days of the date on your REG-06 registration certificate. The advisory does not say what happens if this is missed.

    Why won't my application number come through?

    The system checks your company or LLP identification number online before generating the application number. If the check fails, the application number is not issued and your application is delayed.
