Documents Required for GST Registration in India – Complete 2026 Checklist

Preparing the correct documents required for GST registration in India is one of the most important steps in obtaining a Goods and Services Tax Identification Number (GSTIN). Incomplete documents, inconsistencies in the business address, incorrect constitution documents or an improper authorisation can result in a clarification notice in FORM GST REG-03 and delay registration.

The documents required depend upon the constitution of the applicant, nature of possession of the principal place of business, identity of the promoters or partners, authorised signatory and certain special circumstances. The official GST registration application is filed through the GST Portal.

This guide provides a practical GST registration document checklist for proprietorships, partnership firms, LLPs, private and public companies, HUFs, trusts, societies, foreign-owned Indian companies and applicants operating from owned, rented, consent or shared premises.

Businesses requiring complete filing assistance can refer to our GST Registration Services in India. For the complete filing sequence, read our GST Registration Procedure in India.

GST Registration Documents – Quick Checklist

Core documents normally required

Depending upon the constitution and circumstances of the applicant, the principal document categories for GST registration generally include:

• PAN and basic taxpayer information;
• proof of constitution of business, where applicable;
• photograph of the relevant stakeholder;
• photograph of the authorised signatory;
• proof of appointment of authorised signatory;
• proof of principal place of business;
• proof relating to additional places of business, where applicable; and
• other information required in FORM GST REG-01.

Documents depend on business constitution

A proprietorship does not have the same constitutional documentation as a company, LLP or partnership firm. Therefore, the applicant should first identify the correct constitution of business before preparing the document package.

Business premises documents are particularly important

A significant part of GST registration verification relates to the principal place of business. The required documents differ depending upon whether the premises are owned, rented, leased, shared or used with the consent of the owner.

Why GST Registration Documents Differ for Every Applicant

Constitution of business determines entity documents

FORM GST REG-01 requires information according to the legal structure of the applicant. A company normally relies on its Certificate of Incorporation, while a partnership firm generally relies on its Partnership Deed. Trusts, societies and similar entities may require their registration certificate or other proof of constitution.

Nature of possession determines address documents

The documentation for the principal place of business depends on whether the applicant owns the premises, occupies it under a rent or lease agreement, operates from shared premises or uses the property with the owner’s consent.

Additional verification may depend on application risk parameters

The GST registration system also provides for Aadhaar authentication, biometric-based verification and physical verification in specified situations. Accordingly, applicants should ensure that their identity, promoter, authorised-signatory and business-address information is accurate and capable of verification.

Basic Information and Documents for GST Registration

PAN and legal name of applicant

PAN is fundamental to normal GST registration. The legal name entered in FORM GST REG-01 should match the name available against the PAN. PAN information is validated electronically as part of the registration process.

Applicants should avoid entering abbreviations, trade names or spelling variations in place of the legal name appearing in the PAN database.

Mobile number and e-mail address

A valid mobile number and e-mail address should be kept available for OTP verification, portal communication and subsequent registration correspondence.

Where an authorised signatory is responsible for GST compliance, the contact information entered in the application should be accessible to the person handling the registration process.

Photograph of stakeholder and authorised signatory

The GST Portal’s official registration document checklist provides for photographs of the relevant stakeholder and authorised signatory. The photograph should be clear and uploaded in the prescribed electronic format and file size.

The exact persons whose details are required depend upon the constitution of the applicant, such as proprietor, partners, directors, Karta or members of the governing body.

Documents Required for GST Registration of Proprietorship

Documents of the proprietor

A sole proprietorship does not have a legal identity separate from its proprietor for PAN purposes. The GST registration is therefore linked to the proprietor’s PAN.

The applicant should keep the proprietor’s PAN particulars, contact details, photograph, Aadhaar-related information where applicable and the information required in FORM GST REG-01 ready.

Business premises documents for proprietorship

The proprietor must also provide appropriate proof of the principal place of business. Depending upon the nature of possession, this may include an electricity bill, property tax receipt, Municipal Khata, rent or lease agreement, consent letter or another acceptable ownership or occupancy document.

For a detailed explanation of the online filing process, see our GST Registration Procedure in India.

Documents Required for Partnership Firm and LLP GST Registration

Partnership firm documents

For a partnership firm, the Partnership Deed is an important proof of constitution. CBIC Instruction No. 03/2025-GST specifically states that where the applicant is a partnership, the Partnership Deed is required as proof of constitution and unnecessary additional documents such as Udyam certificate, MSME certificate, Shops and Establishments certificate or trade licence should not routinely be demanded merely for proving constitution.

LLP registration documents

An LLP should provide its prescribed proof of constitution, such as the applicable Certificate of Incorporation or registration document, together with information relating to its designated partners and authorised signatory as required in the registration application.

The document should clearly identify the legal name of the LLP and correspond with its PAN and GST application particulars.

Authorisation for partnership or LLP

Where one partner, designated partner, employee or another permitted person acts as the authorised signatory, the appropriate letter of authorisation, resolution or other prescribed proof of appointment should be uploaded.

Applicants should ensure that the authorised signatory details in REG-01 agree with the authorisation document.

Documents Required for GST Registration of a Company

Certificate of Incorporation

For an Indian company, the Certificate of Incorporation issued by the Ministry of Corporate Affairs is one of the principal documents establishing constitution of the business for GST registration purposes.

The company’s legal name, CIN and PAN particulars should be consistent across the GST application and corporate records.

Director and authorised signatory information

The prescribed details relating to directors or other promoters and the primary authorised signatory must be provided in the registration application. Photographs and relevant identification particulars should be kept ready in accordance with portal requirements.

Companies being incorporated or commencing operations in India may also refer to our Company Registration Services in India.

Board Resolution or authorisation

The official GST registration checklist recognises a Letter of Authorisation or a copy of the resolution passed by the Board of Directors or Managing Committee together with the applicable acceptance as proof of appointment of the authorised signatory.

The authorisation should clearly establish the authority of the person who will file, verify and manage GST-related matters for the company.

Documents for HUF, Trust, Society, Club and Other Entities

HUF GST registration documents

For a Hindu Undivided Family, the registration particulars should appropriately identify the HUF, its PAN, Karta and authorised signatory, together with the relevant place-of-business documentation.

Trust, society or club

CBIC’s registration-processing instructions state that where the applicant is a society, trust, club, Association of Persons, Body of Individuals or similar entity, the applicable Registration Certificate or proof of constitution should be uploaded.

Statutory bodies and other organisations

Government departments, local authorities, statutory bodies and other special categories should provide the proof of constitution or registration applicable to their legal form and complete REG-01 according to the category selected on the portal.

Businesses that require multiple statutory registrations can also review our Business Licences & Statutory Registrations in India.

Documents for GST Registration from Owned Premises

Acceptable ownership documents

For an owned principal place of business, CBIC Instruction No. 03/2025-GST states that any one document which clearly establishes ownership should generally be sufficient.

Examples include:

• latest Property Tax Receipt;
• Municipal Khata copy;
• electricity bill;
• water bill; or
• another document prescribed under State or local law which clearly establishes ownership.

One ownership document should generally be sufficient

CBIC has specifically instructed GST officers that where one appropriate ownership document has been uploaded, unnecessary additional documents should not be sought merely for proving ownership of the premises.

Original physical copies should also not ordinarily be demanded simply because the registration application is being processed electronically.

Documents for GST Registration from Rented or Leased Premises

Valid rent or lease agreement

Where the principal place of business is rented or leased, the applicant should ordinarily upload a valid rent or lease agreement together with appropriate evidence establishing ownership of the premises by the lessor.

Ownership evidence may include an electricity bill, property tax receipt, Municipal Khata or another acceptable ownership document.

Registered rent or lease agreement

Where the rent or lease agreement is registered, CBIC Instruction No. 03/2025-GST states that the registered agreement together with one appropriate ownership document should generally suffice. The lessor’s identity proof should not ordinarily be required merely because the premises are rented.

Unregistered rent or lease agreement

Where the rent or lease agreement is not registered, the CBIC instruction provides that the agreement, one suitable ownership document and a copy of the lessor’s identity proof should generally be sufficient.

If the electricity or water connection is already in the name of the applicant tenant, the relevant bill together with the rent agreement may be accepted in accordance with the CBIC instruction.

Applicants considering serviced or flexible premises may also read our Virtual Office Address for GST Registration guide.

Documents for Consent and Shared Business Premises

Premises owned by spouse or relative

Where the business uses premises belonging to a spouse, relative or another person without a normal rental arrangement, the owner may provide a consent letter permitting use of the property for the applicant’s business.

Consent letter and ownership evidence

CBIC Instruction No. 03/2025-GST provides that a consent letter on plain paper, identity proof of the person granting consent and one acceptable document establishing ownership of the premises should generally suffice.

The ownership document may include a property tax receipt, Municipal Khata, electricity bill, water bill or another document recognised under applicable State or local law.

Shared premises

Where premises are shared and a rent or lease agreement exists, the applicable agreement together with ownership evidence can be uploaded.

If there is no rent or lease agreement, a consent letter, identity proof of the consenter and suitable ownership evidence may be used in accordance with the applicable CBIC instructions.

Documents for Additional Place of Business

Proof for branch, warehouse or other additional location

A registered person may have additional places of business such as branches, offices, warehouses, godowns, factories or other operational premises within the same State or Union Territory.

The GST Portal permits documentary proof relating to the nature of possession of an additional place of business, including ownership documents, rent or lease agreements and consent-related documents, as applicable.

Documents should match the additional address disclosed

The address appearing in the supporting document should correspond with the location entered in the registration application. Building number, floor, locality, PIN code and other address particulars should be checked carefully before submission.

Businesses operating from more than one State should separately examine whether GST registration is required in each relevant State because GST registration is State-specific.

Authorised Signatory Documents and Digital Signature

Letter of Authorisation

The official GST document checklist recognises a Letter of Authorisation as proof of appointment of an authorised signatory.

The letter should clearly identify the applicant and the person authorised to undertake GST registration and related portal activities.

Board or managing committee resolution

Companies and other entities governed through a Board or Managing Committee may use the applicable resolution and acceptance document as prescribed for establishing authority of the authorised signatory.

Digital Signature Certificate where applicable

Applicants should ensure that the relevant Digital Signature Certificate or other permitted electronic verification facility is available where required for submission of the GST application.

The person whose DSC is used should be properly recorded as an authorised signatory on the GST Portal.

Aadhaar Authentication and Biometric Verification Documents

Aadhaar authentication during GST registration

Aadhaar authentication forms part of the GST registration verification framework for applicable applicants. Depending upon the constitution, authentication can involve the primary authorised signatory and the prescribed promoter, partner, director or other relevant person.

Applicants can refer to the official GST Portal Aadhaar Authentication FAQs.

Biometric-based Aadhaar authentication

Where the portal directs an applicant to biometric-based Aadhaar authentication and document verification, the specified individuals should follow the instructions generated through the GST registration system and attend the designated verification facility where required.

Original identity and application-related documents should be carried where the portal communication specifically requires verification.

Cases where Aadhaar authentication is not completed

Where Aadhaar authentication is not opted for, fails or the application is selected for additional verification, the registration may be subjected to physical verification of the place of business or other verification in accordance with the CGST Rules.

Complete and consistent documentation can substantially reduce avoidable REG-03 queries during this process.

Bank Account Documents for GST Registration

Bank details are generally furnished after GSTIN is granted

For normal taxpayers, bank-account information is generally furnished after GST registration has been granted rather than being treated as an essential document for obtaining the initial GSTIN.

Under Rule 10A of the CGST Rules, an applicable registered person is required to furnish bank-account information after registration within the prescribed period.

Documents commonly used for bank verification

Depending upon the GST Portal’s requirements, suitable evidence may include a cancelled cheque, bank statement or other document containing the registered person’s bank-account information.

The bank account should appropriately correspond with the registered person and applicable PAN requirements.

The GST Portal presently requires applicable taxpayers to update bank details within 45 days from grant of registration or before the due date of the return under Section 39, whichever is earlier.

GST Registration Documents for Foreign-Owned and Special Cases

Foreign-owned Indian company

An Indian company does not become a non-resident taxable person merely because its shareholders or parent company are located outside India. A foreign-owned Indian subsidiary normally applies for GST registration as an Indian company using its Indian corporate and business-premises documentation.

The GST documentation may therefore include its Certificate of Incorporation, Indian PAN, promoter or director particulars, authorised-signatory documentation and Indian principal place-of-business proof.

Foreign investors establishing operations in India can also refer to our Business Setup Services in India.

Non-resident taxable person

A non-resident taxable person is a separate GST category subject to a special registration process and should not be confused with an Indian company that happens to have foreign shareholders.

Different forms, identification documents, authorised-person arrangements, advance tax requirements and registration procedures may apply to a non-resident taxable person.

SEZ unit or SEZ developer

Where the principal place of business is located in a Special Economic Zone or the applicant is an SEZ developer, CBIC’s registration instructions provide for submission of the necessary document or certificate issued by the Government of India relating to the SEZ status.

GST Document Format, File Size and Verification

Official GST document upload formats

The GST Portal document checklist specifies electronic formats such as PDF and JPEG/JPG for prescribed attachments. The permitted file size differs according to the type of attachment.

For example, the official checklist currently provides limits including 100 KB for certain photographs and authorisation documents and up to 1 MB for several constitutional, rent or lease and supporting documents.

Applicants should confirm the live portal limit while filing because portal specifications may be updated.

Documents must be clear and legible

Scanned documents should be complete, readable and properly oriented. Pages should not be cut off, blurred or uploaded upside down.

If a document is incomplete or illegible, the proper officer may seek a clearer or complete copy through FORM GST REG-03.

Address and application information must correspond

The proper officer may cross-check the principal and additional place-of-business addresses with documents and publicly available databases such as municipal, electricity or property records.

Applicants should therefore avoid differences in flat number, building number, street name, locality or PIN code between REG-01 and supporting documents unless the difference can be properly explained.

Common GST Registration Document Mistakes

Uploading unnecessary documents instead of correct documents

Uploading a large number of documents does not necessarily strengthen a GST registration application. The better approach is to provide the documents prescribed for the relevant category and make sure they clearly establish the required fact.

CBIC Instruction No. 03/2025-GST specifically addresses the problem of unnecessary documents being sought during registration and instructs officers to adhere to the prescribed requirements.

Mismatch in name, address or authorisation

Common problems include:

• legal name not matching PAN;
• incorrect constitution of business;
• business address differing from the uploaded proof;
• expired or incomplete rent agreements;
• owner’s name not supported by the ownership document;
• missing consent letter for consent premises;
• incorrect authorised signatory;
• resolution not identifying the authorised person;
• unclear or incomplete scans; and
• different addresses appearing across the application and attachments without explanation.

A document review before filing can help reduce clarification notices and delays.

Frequently Asked Questions on GST Registration Documents

What are the main documents required for GST registration?

The principal documents generally relate to the applicant’s constitution, relevant stakeholder photograph, authorised signatory, proof of appointment of authorised signatory and principal place of business. The exact list depends upon the legal structure and circumstances of the applicant.

Is a rent agreement compulsory for GST registration?

No. A rent agreement is relevant where the premises are actually occupied under a rental or lease arrangement. Owned premises, consent premises and shared premises may be supported through different documents in accordance with the GST registration requirements and CBIC instructions.

Is landlord PAN or Aadhaar compulsory for GST registration?

Not in every rented-premises case. Under CBIC Instruction No. 03/2025-GST, where a registered rent or lease agreement is provided together with appropriate ownership evidence, the lessor’s identity proof should ordinarily not be sought merely for the GST registration.

For an unregistered rent or lease agreement, the instruction provides for the agreement, suitable ownership proof and identity proof of the lessor.

Can a consent letter be used for GST registration?

Yes. Where the premises belong to a spouse, relative or another person and are made available with consent, a consent letter together with the prescribed identity and ownership evidence can be used in appropriate cases.

Is an electricity bill mandatory for GST registration?

An electricity bill is one recognised document for establishing ownership or address, but it is not the only acceptable document in every case. Depending upon the facts, a property tax receipt, Municipal Khata, water bill or another acceptable ownership document may also be used.

Can GST officers demand extra documents?

A proper officer may seek a relevant clarification or document where there is an actual deficiency, inconsistency or verification issue. However, CBIC Instruction No. 03/2025-GST directs officers not to raise unnecessary presumptive queries or routinely demand documents beyond the prescribed list without proper justification.

Are bank account documents required before GST registration?

For the normal registration process, bank-account details are generally furnished after the GSTIN has been granted. Rule 10A requires applicable registered persons to furnish bank-account information within the prescribed post-registration period.

What documents are required for a private limited company?

A private limited company normally requires its Certificate of Incorporation as proof of constitution, relevant director or promoter and authorised-signatory information, photograph as applicable, proof of appointment of authorised signatory and proper proof of the principal place of business.

The company’s PAN, mobile number, e-mail and other information required in REG-01 should also be available.

What happens if GST registration documents are incomplete?

The proper officer may issue FORM GST REG-03 seeking clarification, information or proper supporting documentation. The applicant is required to respond through the prescribed process, generally using FORM GST REG-04.

For the full registration and clarification procedure, refer to our GST Registration Procedure in India.

Do I need professional assistance for GST registration?

Simple applications may be filed directly by eligible applicants through the GST Portal. Professional assistance can be useful where the entity has foreign ownership, multiple States, unusual premises arrangements, complex constitution, previous rejected registrations, Aadhaar or physical-verification issues or REG-03 clarification notices.
