Core Documents Required for GST Registration
Every GST applicant in India must prepare a set of core documents to ensure a smooth registration process. These are fundamental for identification and authentication purposes.
PAN Card: Serves as the primary identification for the business or proprietor.
Aadhaar Card: Required for the proprietor, partners, or directors; enables OTP-based authentication during filing. Foreign nationals may use their passport instead.
Photographs: Passport-sized (3x4 cm) images in JPEG format of the proprietor, partners, or directors.
Business Address Proof:
Owned property: electricity bill, property tax receipt, municipal khata.
Rented property: notarised rent agreement or consent letter with landlord documents.
Bank Account Proof: Cancelled cheque, bank statement, or passbook extract. While not always mandatory upfront, this is needed for verification post-registration.
TaxBuddy simplifies this step by allowing users to upload these documents directly via its portal or mobile app, flagging incomplete or mismatched files to prevent rejection.
GST Registration Documents by Business Type
GST document requirements vary depending on the business structure. Here is a clear breakdown:
Business Type | Key Additional Documents | Common Proofs Accepted |
Sole Proprietor | None beyond basics | Electricity bill, rent agreement |
Partnership Firm | Partnership deed | PAN and Aadhaar of all partners, address proofs |
Private Limited Company / LLP | Incorporation certificate, MOA, AOA, board resolution | Directors’ IDs or passports, business address proofs |
Trust / Society | Trust deed, registration certificate | Trustees’ IDs, property or utility proofs |
Sole proprietors require only the core documents, while partnerships, companies, LLPs, and trusts need extra legal or registration certificates. TaxBuddy provides a step-by-step checklist for each type, ensuring that all mandatory documents are uploaded correctly before filing the GST application.
Special Cases: NRIs, Non-Residents, and Digital Signatures
Certain cases require special attention:
NRIs and Non-Residents: Aadhaar can be replaced with a passport. The bank account must be in India.
Digital Signatures: Companies and LLPs must use Class 2 or Class 3 digital signatures for authentication.
Multiple Locations or Rented Premises: Consent letters and landlord ID proofs may be necessary for properties that are shared or rented.
TaxBuddy identifies these special cases during the upload process, prompting users for the exact documents required and reducing the chances of errors. This ensures compliance with the latest GST regulations.
Tips for Smooth GST Document Submission via TaxBuddy
Submitting documents correctly is crucial for a hassle-free GST registration process. TaxBuddy simplifies this task, but careful preparation ensures faster verification and approval.
Scan Documents Clearly: Clarity is essential when uploading identity, address, and business proofs. Blurry images, cropped edges, or incomplete scans can lead to delays or rejection. Use a good scanner or a high-quality smartphone camera. Ensure the file size and resolution meet TaxBuddy’s requirements, typically JPEG or PDF formats. Clear scans help both the platform and GST authorities verify information efficiently.
Verify Address Proof Validity: Address documents, such as utility bills, rent agreements, property tax receipts, or municipal khata, must be recent and valid. For most submissions, utility bills should not be older than two months. Providing outdated proofs can result in application rejection or additional verification requests. TaxBuddy alerts users if the uploaded address proof does not meet these standards, guiding them to upload valid alternatives.
Check Names Carefully: Consistency across documents is vital. The names on PAN, Aadhaar, photographs, and bank proofs must match exactly. Even minor spelling errors or mismatched initials can trigger verification failures. TaxBuddy automatically checks for such discrepancies and prompts corrections before submission, helping users avoid repeated uploads and delays.
Keep Multiple Copies: Always maintain both original documents and digital scans for submission. Originals are useful if verification authorities request physical proofs, while digital copies allow quick uploads and backups. TaxBuddy’s platform supports secure storage of these scans, making it easier to manage multiple documents without losing any important information.
Follow TaxBuddy’s Prompts: TaxBuddy’s portal and mobile app provide step-by-step guidance for document uploads. The platform flags missing, mismatched, or improperly formatted documents in real time, reducing the chances of rejection. Following these prompts ensures that every document is submitted correctly the first time correctly, saving time and effort.
Upload in Order: A structured upload sequence improves efficiency. Start with identity proofs like PAN and Aadhaar, or a passport. Next, submit business address proofs. Finally, provide bank account documents such as cancelled cheques or passbook extracts. This logical sequence aligns with TaxBuddy’s internal verification process and helps authorities validate the application smoothly.
By following these tips, applicants can streamline the GST registration process, reduce errors, and ensure faster approval. Using TaxBuddy’s guided uploads and real-time checks makes the entire process accurate, organised, and stress-free.
Latest GST Registration Updates for 2025
The GST registration process continues to evolve, and staying updated with the latest requirements is essential for seamless compliance. One of the key changes in 2025 is the mandatory linking of Aadhaar with PAN for individuals. This linkage allows the GST authorities to verify identity quickly and accurately through an OTP-based authentication system. For proprietors, partners, or directors, completing this step ensures that the registration process is smooth and reduces the risk of discrepancies or rejections due to unverified identification.
Another important update concerns the validity of address proof documents. Utility bills such as electricity, water, or gas bills used to verify the business address must now be no older than two months. This ensures that the registered business address reflects the current location of operations. Outdated documents may lead to delays or rejection of the application, making it crucial to prepare recent proofs. TaxBuddy automatically checks for document validity during uploads, guiding users to provide acceptable and up-to-date proofs.
For companies and limited liability partnerships, digital signatures remain a critical requirement. Class 2 or Class 3 digital signature certificates are necessary for authenticating documents submitted during GST registration and filing. Digital signatures not only validate the authenticity of the applicant but also ensure compliance with security standards. TaxBuddy’s platform supports the secure upload and verification of these digital certificates, reducing errors and saving time during submission.
The process of uploading documents has also been streamlined significantly in 2025. TaxBuddy’s portal now includes pre-check mechanisms that flag missing, incorrect, or mismatched documents before the final submission. This proactive verification helps applicants correct mistakes early, ensuring that the GST registration process is completed efficiently without unnecessary delays.
Finally, official forms such as REG-01 continue to serve as the standard for GST registration. Available on the GST portal, these forms remain the basis for all applications across different business types. TaxBuddy integrates the requirements of REG-01 into its workflow, prompting users to provide the correct documents and details in the proper format. By combining these updates with a structured and guided submission process, TaxBuddy ensures that applicants can comply with the latest GST regulations without confusion or repeated back-and-forth submissions.

Preparing all required GST registration documents carefully ensures a smooth and hassle-free application. TaxBuddy helps applicants navigate this process with clear prompts, real-time verification, and structured upload guidance.

FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options?
TaxBuddy provides both self-filing and expert-assisted options. The self-filing plan is ideal for individuals or businesses with straightforward income sources, allowing AI-assisted document uploads, automated calculations, and guided steps to complete the return. The expert-assisted plan is designed for taxpayers with multiple income streams, capital gains, foreign assets, or complex business structures.

Both plans are integrated into TaxBuddy’s portal and mobile app, providing flexibility based on the user’s familiarity with tax procedures.
Q2. Which is the best site to file ITR
While the official income tax portal is widely used, TaxBuddy offers a more user-friendly and guided experience. It simplifies form filling, automatically reads Form 16 and bank statements, validates documents, and checks for common errors. Its AI-assisted interface reduces manual effort, ensures accuracy, and guides users through exemptions and deductions, making it suitable for both beginners and experienced taxpayers.

Q3. Where to file an income tax return?
Income tax returns can be filed via the official income tax e-filing portal (incometax.gov.in) or using trusted platforms like TaxBuddy. Filing through TaxBuddy provides additional guidance such as automated document reading, real-time validation, and AI-driven deduction suggestions. Users can complete the entire filing process, including uploading Form 16, bank details, and other proofs, directly through the mobile app or portal. For individuals with complex income sources or business income, expert-assisted filing ensures compliance and accuracy, making TaxBuddy a reliable option.
Q4. Are Aadhaar and PAN mandatory for GST registration?
Yes, Aadhaar and PAN are key identification requirements for GST registration. Aadhaar is mandatory for individuals, proprietors, and partners, enabling OTP-based authentication for verification. PAN is mandatory for all businesses, serving as the primary identification for the entity. For companies and LLPs, entity PAN along with directors’ IDs are required. Non-residents and foreign applicants may use their passport in place of Aadhaar. TaxBuddy ensures all such identification documents are uploaded correctly, flagging mismatches to prevent delays.
Q5. Can bank details be added after filing GST?
Yes, bank details can be added or updated after filing GST through an amendment process. While some business types may be required to submit bank details during registration, others can provide them post-registration. TaxBuddy guides users through the amendment process, allowing secure uploads of cancelled cheques, passbook extracts, or bank statements. This ensures that the registered account is verified for refunds and compliance purposes, minimizing the risk of errors or payment delays.
Q6. What is the validity period for address proofs?
For GST registration, address proofs must be recent and verifiable. Utility bills, property tax receipts, municipal khata, or rent agreements must generally not be older than two months. If documents are outdated, applications can be delayed or rejected. TaxBuddy checks the validity of address proofs during the upload process and prompts users to provide alternative documents if necessary, ensuring smooth verification and avoiding processing issues.
Q7. Are digital signatures compulsory for all businesses?
Digital signatures are mandatory only for companies and LLPs when filing GST registration and other returns. Sole proprietors and partnership firms generally do not require them, unless specific compliance requirements dictate otherwise. Class 2 or Class 3 digital signatures are commonly accepted. TaxBuddy supports uploading and verification of digital signature certificates, ensuring they meet the regulatory standards and preventing filing errors related to authentication.
Q8. Can NRIs register for GST in India?
Yes, NRIs and non-resident taxpayers can register for GST in India. A valid passport replaces Aadhaar for identity verification, and an Indian bank account is mandatory for refunds and compliance purposes. TaxBuddy guides NRIs through document requirements, including passport copies, photograph uploads, and proof of Indian bank account, ensuring the registration process meets all legal obligations.
Q9. What formats are accepted for document uploads on TaxBuddy?
TaxBuddy accepts clear, legible formats such as JPEG, PDF, or scanned copies. Images must be readable, and documents should be complete without any cuts or blurry sections. For photographs, the recommended size is 3x4 cm in JPEG format. Proper formatting ensures that the uploaded documents are verified successfully, reducing the chances of delays or rejection by GST authorities.
Q10. What should I do if a rent agreement is unregistered?
If a property is rented and the agreement is unregistered, applicants must submit an affidavit affirming the rental arrangement, accompanied by the landlord’s utility bill or ID proof. This provides alternative verification for GST authorities. TaxBuddy allows users to upload such affidavits and supporting documents securely, ensuring compliance with GST rules and minimizing errors during the registration process.
Q11. Does TaxBuddy check for document mismatches?
Yes, TaxBuddy actively checks for mismatches or discrepancies in uploaded documents. The platform compares names, addresses, and identification numbers across PAN, Aadhaar, photographs, and bank proofs. Any errors are flagged for correction before submission, reducing the likelihood of application rejection. This feature ensures a smooth GST registration experience and provides peace of mind to users.
Q12. Is there a difference in documents for different business types?
Yes, GST registration documents vary by business type. Sole proprietors typically need only core documents such as PAN, Aadhaar, photographs, address, and bank details. Partnerships require additional documents like partnership deeds and PAN/Aadhaar for all partners. Companies and LLPs must submit incorporation certificates, MOA/AOA, board resolutions, and directors’ identification. Trusts and societies provide registration certificates or trust deeds along with trustee IDs. TaxBuddy organizes document checklists for each business type, ensuring that nothing is missed during the filing process.
