Let’s dive into understanding eligibility, gathering documents, navigating the online process, understanding the benefits of GST registration, ensuring compliance, and addressing frequently asked questions. You might also want to calculate your potential GST liability early on.

What is GST and Why is Registration Necessary?

What is GST? Goods and Services Tax (GST) is a unified indirect tax implemented in India in 2017, replacing multiple cascading taxes like VAT, Service Tax, and Excise Duty. It operates on a dual model: Central GST (CGST) collected by the Central Government and State GST (SGST) collected by the State Government for intra-state transactions, and Integrated GST (IGST) collected by the Central Government for inter-state transactions and imports.

The primary purpose of GST registration is multifold. Firstly, it provides legal recognition to your business as a supplier of goods or services. Secondly, registration legally authorizes you to collect GST from your customers on behalf of the government. Perhaps one of the most significant benefits of GST registration is the ability to claim Input Tax Credit (ITC). ITC allows you to deduct the GST paid on your business purchases (inputs) from the GST collected on your sales (outputs), effectively reducing your final tax liability. Furthermore, GST registration is often mandatory for engaging in inter-state trade and enhances your business’s credibility with suppliers and customers.

Failure to register for GST when legally required can lead to significant consequences, including heavy penalties and legal action. Upon successful registration, you are assigned a unique 15-digit GSTIN (Goods and Services Tax Identification Number). This GST number becomes your primary identifier for all GST-related compliance activities, including invoicing and return filing.

Who Needs GST Registration in India? (Eligibility Criteria 2025)

Understanding GST registration eligibility is the first critical step. Registration isn’t required for everyone; it primarily depends on your business’s aggregate turnover and specific activities. Let’s break down the criteria for 2025.

Turnover Thresholds

The primary trigger for GST registration is crossing a specified annual ‘aggregate turnover’ limit. Aggregate turnover includes the total value of all taxable supplies, exempt supplies, exports, and inter-state supplies made by a person having the same Permanent Account Number (PAN), calculated on an all-India basis.

• Supply of Goods:
  • ₹40 Lakhs: For most states (‘Normal Category States’). Businesses exceeding this turnover in a financial year must register.
  • ₹20 Lakhs: For ‘Special Category States’. (See list below).
• Supply of Services:
  • ₹20 Lakhs: For most states (‘Normal Category States’).
  • ₹10 Lakhs: For ‘Special Category States’.

Special Category States for GST purposes have lower thresholds due to specific economic factors. As of recent updates, the states with adjusted thresholds are:

• ₹20 Lakhs (Goods) / ₹10 Lakhs (Services): Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Puducherry, Sikkim, Tripura, Uttarakhand.
• Note: Some states previously listed as Special Category (like Assam, Jammu & Kashmir, Himachal Pradesh, Ladakh) have opted for the higher thresholds (₹40 Lakhs for goods / ₹20 Lakhs for services).

GST Registration Turnover Limit Comparison (2025)

Category	Type of Supply	Normal Category States	Special Category States*
Turnover Limit	Goods	₹40 Lakhs	₹20 Lakhs
	Services	₹20 Lakhs	₹10 Lakhs
*Key Special Category States with lower limits: Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Puducherry, Sikkim, Tripura, Uttarakhand.

Mandatory GST Registration Scenarios (Irrespective of Turnover)

Certain businesses must register for GST regardless of their turnover. This includes:

1. Inter-state Suppliers: Persons making any inter-state taxable supply of goods. (Note: Threshold limits apply for inter-state supply of services).
2. Casual Taxable Persons (CTP): Individuals occasionally undertaking transactions involving taxable supply in a state where they don’t have a fixed place of business.
3. Non-Resident Taxable Persons (NRTP): Similar to CTPs but residing outside India.
4. Reverse Charge Mechanism (RCM) Payers: Businesses required to pay tax under the RCM.
5. Agents & Input Service Distributors (ISD): Agents supplying on behalf of principals and ISDs. Important: From April 1, 2025, ISD registration is mandatory for businesses with multiple GSTINs under the same PAN distributing common input service credit.
6. E-commerce Operators & Suppliers: E-commerce aggregators and businesses supplying goods or services through e-commerce platforms where Tax is Collected at Source (TCS) applies (except for suppliers of services notified under Sec 9(5)). GST registration for e-commerce seller is crucial.
7. OIDAR Service Providers: Persons providing Online Information and Database Access or Retrieval services from outside India to a non-registered person in India.
8. TDS Deductors: Persons required to deduct Tax at Source under GST.

Voluntary GST Registration

Even if not mandatory, businesses can opt for voluntary GST registration. Benefits include being able to issue tax invoices, claim ITC on purchases, improve business credibility, and facilitate inter-state trade without restrictions.

GST Registration Exemptions

Certain categories are exempt from GST registration, such as agriculturists supplying produce from cultivation and persons exclusively supplying goods/services not liable to GST or wholly exempt. Check the GST registration exemption list for specifics.

Complete Checklist: Documents Required for GST Registration (Updated for 2025)

Gathering the correct documents for GST registration is crucial for a smooth application process. Requirements vary slightly based on the business constitution. Here’s a comprehensive GST registration documents checklist for 2025.

Common Documents for All Applicants

These documents are generally required irrespective of your business type:

1. PAN Card: Permanent Account Number (PAN) of the individual, company, LLP, or HUF is mandatory. The business name on the application must match the PAN record.
2. Aadhaar Card: Required for the primary applicant (proprietor, partners, directors, Karta) and essential for Aadhaar authentication.
3. Photograph: Recent passport-size photograph(s) of the applicant(s) (proprietor, partners, directors, Karta, authorised signatory) in JPEG format (usually max 100 KB).
4. Proof of Principal Place of Business: This is a critical document with specific requirements depending on ownership/rental status (details below).
5. Bank Account Proof: Proof of the business’s bank account, such as a scanned copy of a cancelled cheque (with account holder name), bank statement, or the first page of the passbook. The account name should ideally match the business/trade name.

Proof of Principal Place of Business

This is often the most scrutinized document, especially address proof for GST. Ensure you have valid proof for your main business location:

• Owned Property: Any one of the following in the name of the owner (business or proprietor/partner/director):
  • Latest Property Tax Receipt
  • Municipal Khata Copy
  • Electricity Bill copy (latest, typically within 2-3 months)
  • Legal ownership document (e.g., Sale Deed)
• Rented Property: All of the following:
  • Valid Rent/Lease Agreement.
  • Any one proof of ownership in the landlord’s name: Latest Property Tax Receipt / Municipal Khata Copy / Electricity Bill.
  • No Objection Certificate (NOC) from the property owner. This is crucial if the rent agreement is old/expired or doesn’t explicitly permit GST registration. Ensure consistency between names on bills and the agreement.
• Leased Property: Similar documents as rented property, including the Lease Agreement.
• Consent/Shared Premises (e.g., Home Office, Relative’s Property): This addresses GST registration for freelancers India using home offices.
  • Consent Letter or NOC from the property owner clearly stating permission to use the premises for business.
  • Any one proof of ownership in the owner’s name (e.g., Electricity Bill). Address verification for home offices can be a GST registration address verification problem, so ensure the NOC is clear.
• Co-working/Virtual Office: Using a virtual office for GST registration is possible but subject to scrutiny. Required documents typically include:
  • Valid Agreement with the virtual office provider.
  • NOC from the provider.
  • Utility bill in the provider’s name for the location. State regulations may vary, so verify acceptance.

Business Constitution Proof (Specific Documents by Entity Type)

In addition to common documents, specific proofs are needed based on your business structure:

• Sole Proprietorship: Generally, no separate business constitution proof is needed beyond the proprietor’s PAN, Aadhaar, photo, address, and bank proof.
• Partnership Firm (including LLP):
  • Partnership Deed.
  • PAN Card of the Firm/LLP.
  • PAN, Aadhaar, and Photo of all Partners (including managing/designated partners).
  • For LLPs: Certificate of Incorporation, LLP Deed.
  • Proof of appointment of Authorised Signatory (Authorisation Letter or Board Resolution for LLP).
• Company (Private Limited / Public Limited / OPC):
  • Certificate of Incorporation issued by the Ministry of Corporate Affairs (MCA).
  • PAN Card of the Company.
  • Memorandum of Association (MOA) / Articles of Association (AOA).
  • PAN, Aadhaar, and Photo of all Directors.
  • PAN, Aadhaar, and Photo of the Authorised Signatory.
  • Board Resolution appointing the Authorised Signatory.

   • Verification Tab / Aadhaar Authentication: This is a crucial step. You will be asked if you want to opt for Aadhaar Authentication.
     • Selecting ‘Yes’ is generally recommended for faster processing. An authentication link will be sent to the primary authorised signatory and promoters/partners. Failure to authenticate may lead to mandatory physical verification.
     • Selecting ‘No’ or if authentication fails, mandatory physical verification of the business premises will likely be scheduled by a GST officer.

Application Verification (DSC / EVC / E-Sign)

After filling all details, you need to verify and submit the application. Choose one of the methods:

1. Digital Signature Certificate (DSC): Mandatory for Companies and LLPs. The DSC must be registered on the GST portal beforehand.
2. Electronic Verification Code (EVC): An OTP is sent to the mobile number registered with the Aadhaar of the authorised signatory.
3. E-Sign: An Aadhaar-based electronic signature facility. An OTP is sent to the mobile number linked with the signatory’s Aadhaar card.

Select the verification method, agree to the declaration, and click ‘Submit’.

ARN Generation

On successful submission, an ARN (Application Reference Number) is generated and sent to your registered email and mobile number. This ARN is crucial for tracking the GST registration status.

How to Check GST Registration Application Status (Using ARN)

You can track your application progress online:

1. Go to the GST Portal: https://www.gst.gov.in.
2. Navigate: Services > Registration > Track Application Status.
3. Select ‘ARN’ radio button, enter the ARN received, enter the captcha, and click ‘Search’.
4. The status will be displayed. Common statuses include:
   • Pending for Processing: Application submitted, awaiting officer action.
   • Pending for Clarification: Officer has sought clarification (See Troubleshooting section).
   • Pending for Validation: Awaiting validation after clarification submitted.
   • Approved: Congratulations! Your registration is approved.
   • Rejected: Application rejected (See Troubleshooting section).

Aadhaar Authentication for GST Registration: Importance and Process

Aadhaar authentication has become an integral part of the GST registration process in India. It aims to verify the identity of the applicant, expedite processing, and curb fraudulent registrations.

What is Aadhaar Authentication and Why is it Important?

It’s a process where the applicant’s Aadhaar details (submitted in the registration form) are verified against the UIDAI database. Opting ‘Yes’ for Aadhaar authentication during application filing offers significant benefits:

• Faster Processing: Generally leads to quicker generation of the ARN and faster approval of the registration application.
• Reduced Physical Verification: While not guaranteed, successful Aadhaar authentication often reduces the chances of mandatory physical verification of the business premises by a GST officer. However, the officer retains the right to conduct physical verification based on risk assessment.

The Aadhaar Authentication Process

1. Opt-In: Select ‘Yes’ for Aadhaar Authentication in Part B of the GST REG-01 form.
2. Receive Link: After submitting the application (Part B), an authentication link is sent via email and SMS to the registered mobile numbers/email addresses of the Primary Authorized Signatory and the Promoters/Partners/Directors whose Aadhaar details were provided.
3. Authenticate: Click the link and follow the instructions. Authentication is typically done via Aadhaar OTP sent to the mobile number linked with the respective Aadhaar card.
4. Time Limit: Authentication must be completed within 15 days of receiving the link.

New Update (2025): Biometric Authentication:

• For certain high-risk applicants, including Company Directors/Promoters, mandatory biometric-based Aadhaar authentication is being rolled out phase-wise across states (e.g., Uttar Pradesh, Assam as of early 2025).
• If selected for this, the applicant will receive a link to book an appointment at a designated GST Suvidha Kendra (GSK).
• The process at the GSK involves fingerprint scanning, facial recognition, photograph capture, and physical verification of original documents. ARN generation may be linked to the successful completion of this process.

What Happens if Aadhaar Authentication Fails or is Not Opted For?

If you choose ‘No’ for Aadhaar authentication, or if the authentication fails, the following occurs:

• Mandatory Physical Verification: Your application will be marked for mandatory physical verification of the principal place of business.
• Potential Delays: This inevitably leads to delays in ARN generation and final approval of the GST registration, as the verification needs to be scheduled and conducted by a GST officer.

Common reasons for Aadhaar authentication failed scenarios include:

• Mismatch in Name, Date of Birth, or Gender between PAN/GST application and Aadhaar records.
• Mobile number used for OTP is not linked with the Aadhaar card.
• Technical glitches on the GST portal or UIDAI servers.

Physical Verification Process

If physical verification is triggered, a GST officer will visit the mentioned business premises. They primarily check:

• The existence and operational status of the business premises.
• Verification of original documents submitted with the application.
• Nature of business activities being conducted.

Tips for smooth physical verification: Ensure someone knowledgeable is present, keep original documents handy, ensure the business name board is displayed, and cooperate fully with the officer.

Timelines, Fees, and GST Certificate

Understanding the expected timeframe and costs associated with GST registration helps manage expectations.

How Long Does GST Registration Take?

The GST registration time can vary:

• Ideal Scenario: If you opt for Aadhaar authentication and it’s successful, and the officer raises no queries, approval and GSTIN allotment typically happen within 3-7 working days after ARN generation.
• Physical Verification / Clarification: If physical verification is required (due to failed/no Aadhaar authentication or officer’s discretion) or if the officer seeks clarification (issues Form GST REG-03), the process can take significantly longer, potentially 15-30 working days or more. How many days does it take to get GST number after ARN? depends heavily on these factors.

GST Registration Fees

• Official Government Fee: There is NIL government fee for GST registration itself. Applying on the official GST portal (gst.gov.in) is free.
• Consultant Fees: If you engage a professional (GST registration consultant, CA, Tax Lawyer) for assistance, they will charge a professional fee for their services. These GST registration fees online or offline vary based on the consultant and complexity. Is GST registration free? Yes, the government process is free.

The GST Registration Certificate (Form GST REG-06)

Upon approval of your application, the GST authority issues the GST Registration Certificate in Form GST REG-06.

• What it is: This is the official proof of your GST registration.
• Contents: It contains key details like your Legal Name, Trade Name (if any), GSTIN, Principal Place of Business address, Date of Liability, Date of Registration, Validity (usually indefinite for regular taxpayers), Type of Taxpayer (Regular, Composition, etc.), and Jurisdiction details. It may also have Annexures detailing Additional Places of Business and Authorised Signatories.
• Downloading: You can download the GST certificate from the GST portal after logging in (Services > User Services > View/Download Certificates). It’s recommended to print and display it prominently at your principal place of business.

Critical First Steps After Getting Your GSTIN (Post-Registration Compliance)

Receiving your GSTIN is just the beginning. What to do after getting GSTIN? Immediate post-registration compliance GST actions are crucial to avoid penalties.

1. Display GST Certificate: Print and display your GST Registration Certificate (Form GST REG-06) at your principal place of business and all additional places of business.
2. Update Invoices: Begin issuing GST-compliant invoices with your GSTIN, correct HSN/SAC codes, and the applicable tax rates. Use the new invoice series if required by the latest rules.
3. File Returns: File the applicable GST returns (GSTR-1, GSTR-3B, and others as required) by the due dates. Failure to file can lead to penalties and blocking of e-way bill generation.
4. E-way Bill Registration: If your business involves the movement of goods, register on the E-way Bill portal and comply with e-way bill requirements for applicable transactions.
5. Maintain Books & Records: Maintain proper books of account, including purchase/sale registers, stock records, and records of input tax credit claimed.
6. Stay Updated: Regularly check for new GST notifications, rule changes, and compliance deadlines.
7. Amend Registration if Needed: If your business details change (address, partners, bank account, etc.), amend your GST registration promptly using Form GST REG-14.

Troubleshooting Common GST Registration Problems

Application Stuck at ‘Pending for Clarification’

If your application status is ‘Pending for Clarification’, a GST officer has sought additional information or documents. You must respond to the notice (Form GST REG-03) within 7 working days using Form GST REG-04. Failure to respond leads to rejection.

• Tip: Read the officer’s query carefully, upload clear supporting documents, and provide a concise, factual reply.

Application Rejected

If your application is rejected (Form GST REG-05), you will receive an order with reasons for rejection.

• Options:
  1. File a Fresh Application: Correct the errors or deficiencies mentioned in the rejection order and file a completely new GST registration application (Form GST REG-01). This is often the quickest route.
  2. File an Appeal: If you believe the rejection was unjustified, you can file an appeal with the Appellate Authority (Form GST APL-01) within three months of the rejection order date.

Can a GST application be rejected? Why? Yes, primarily due to incomplete/incorrect information, document issues, or verification failures.

Technical Glitches on the GST Portal

Users sometimes experience technical issues on the GST portal (gst.gov.in).

• Common Issues: Portal downtime during peak filing periods, slow loading speeds, errors while uploading documents, OTP delivery delays.
• Troubleshooting Tips:
  • Clear browser cache and cookies.
  • Try using a different web browser (e.g., Chrome, Firefox, Edge - latest versions).
  • Check if the portal is officially under maintenance (notifications are usually posted).
  • Try accessing during off-peak hours.
  • Ensure your internet connection is stable.
  • If issues persist, contact the GST Helpdesk or raise a grievance through the Grievance Redressal Portal on the GST website.

Special Cases: GST Registration for Freelancers, E-commerce, etc.

Specific business models have unique considerations for GST registration.

GST for Freelancers and Service Providers

GST for freelancers and independent service providers is a common query.

• Eligibility: The turnover threshold is ₹20 Lakhs (or ₹10 Lakhs in Special Category States) based on aggregate annual income from services. Registration is mandatory if this limit is crossed, even if 100% of services are exported.
• Inter-state Services: Unlike goods, the threshold limit does apply for inter-state supply of services. However, registration might be beneficial for claiming ITC.
• Address Proof: Home offices are common. Use the ‘Consent/Shared Premises’ documentation (Consent Letter/NOC + Owner’s proof) as discussed earlier. GST registration address verification problems can arise, so ensure documents are clear.
• Export of Services (LUT): If you provide services to clients outside India and receive payment in convertible foreign exchange, it qualifies as an export of service. To export services without paying IGST, you must file a Letter of Undertaking (LUT) online on the GST portal (Form GST RFD-11) before exporting. This allows zero-rated exports. If you don’t file an LUT, you must pay IGST on export invoices and then claim a refund. Need help? Learn about applying for a Letter of Undertaking (LUT).
• Invoicing Foreign Clients: Invoices should mention Place of Supply rules (generally location of recipient), currency, and indicate export supply (with or without tax payment based on LUT).
• Fluctuating Income: Monitor your turnover closely. Register within 30 days of crossing the applicable threshold.

GST for E-commerce Sellers

GST for e-commerce sellers has specific rules.

• Mandatory Registration: If you supply goods through an E-commerce Operator (ECO) platform (like Amazon, Flipkart) that is liable to collect Tax at Source (TCS) under Section 52, you MUST register for GST, irrespective of your turnover.
• TCS Implications: The ECO deducts TCS (usually 1%) on the net value of taxable supplies made through their platform and deposits it with the government. Sellers can claim credit for this TCS while filing their returns.
• Services via ECO: Threshold limits generally apply if supplying services via ECOs, unless the service falls under Section 9(5) where the ECO pays the GST (e.g., specific transport, accommodation, restaurant services).
• Dropshipping: Address proof can be complex; you might need registration in states where suppliers/inventory are located.

GST Registration Amendments (Core vs. Non-Core)

Once registered, you might need to make changes to your registration details. This is done via GST registration amendment using Form GST REG-14 on the portal. Amendments are categorized:

• Core Fields: Changes to critical details like Legal Name of Business, Principal Place of Business Address, Additional Places of Business, or Addition/Deletion of Partners/Directors/Karta. These require approval from a tax officer and may involve verification. Submit Form GST REG-14 with supporting documents within 15 days of the change.
• Non-Core Fields: Changes to details like Mobile Number, Email Address, Bank Account Details, Authorised Signatory details (other than promoter changes), etc.. These are generally auto-approved upon submission in the portal and don’t require officer intervention.

Ensure timely amendments to avoid compliance issues. Need help? Consider amending your GST registration details.

Key GST Changes and Updates (Effective 2025)

The GST landscape is dynamic. Staying aware of GST updates 2025 and GST rule changes is vital for compliance. Key changes impacting registration and initial compliance include:

1. Mandatory Multi-Factor Authentication (MFA): Starting April 1, 2025, MFA is mandatory for all taxpayers, regardless of turnover, to log in to the GST portal. This enhances security using methods like OTPs in addition to passwords.
2. Mandatory ISD Registration: As mentioned, from April 1, 2025, ISD registration becomes compulsory for businesses with multiple GSTINs under one PAN needing to distribute common input service credits. Filing GSTR-6 is required for ISDs.
3. Mandatory Biometric Authentication: For Company Directors/Promoters and other identified high-risk applicants, biometric-based Aadhaar authentication at designated GST Suvidha Kendras (GSKs) is being implemented phase-wise for new GST registration.
4. New Invoice Series Requirement: Businesses must use a new, unique, and sequential invoice series starting from April 1, 2025 (for FY 2025-26).
5. E-Way Bill Restrictions:
   • 180-Day Invoice Limit: E-Way Bills can only be generated for invoices/documents dated within the preceding 180 days.
   • Extension Cap: E-Way Bill validity extensions are capped at 360 days from the original generation date.
6. Lowered E-invoicing Threshold & Reporting Time: The 30-day time limit for reporting B2B e-invoices on the Invoice Registration Portal (IRP) now applies to taxpayers with an Annual Aggregate Turnover (AATO) above ₹10 Crore (effective April 1, 2025). Previously it was ₹100 Crore.
7. Sequential Filing for GSTR-7: Tax deductors filing GSTR-7 must file returns sequentially for previous periods before filing the current one.
8. GST Waiver Scheme (Amnesty): An opportunity exists (check deadlines, often time-bound like till March 31, 2025 for FYs 17-18 to 19-20) to pay outstanding principal tax for past years to get waivers on interest and penalties.

Frequently Asked Questions (FAQs) about GST Registration

Here are answers to some common questions about GST registration:

1. Is GST registration free? Yes, the process of registering on the official government GST portal (gst.gov.in) is completely free. However, if you hire a consultant (GST registration consultant), they will charge a professional fee.
2. How many days does it take to get GST number after ARN? If Aadhaar authentication is successful and no queries are raised, it typically takes 3-7 working days. If physical verification or clarification (REG-03) is needed, it can take 15-30 days or more.
3. Can I register for GST using my home address? Yes, you can use your home address as the principal place of business, especially for service providers or freelancers. You’ll need to provide valid proof, typically a Consent Letter/NOC from the property owner (if not self-owned) along with their ownership proof (like an electricity bill).
4. What happens if I don’t register for GST when required? Failure to register despite being liable attracts heavy penalties under the GST Act. Penalties can be a percentage of the tax due or a fixed amount, whichever is higher. You may also be liable for the tax from the date you were supposed to register, along with interest. Non-compliance also prevents you from claiming ITC.
5. Do I need a DSC for GST registration? A Digital Signature Certificate (DSC) is mandatory only for Companies (Private Ltd, Public Ltd, OPC) and LLPs. Other applicants like Proprietorships, Partnerships, and HUFs can verify using EVC (Aadhaar OTP) or E-Sign.
6. What is the difference between CGST, SGST, and IGST?
   • CGST (Central GST): Tax collected by the Central Government on intra-state supplies.
   • SGST (State GST): Tax collected by the State Government on intra-state supplies.
   • IGST (Integrated GST): Tax collected by the Central Government on inter-state supplies and imports. It’s levied to ensure seamless credit flow between states.
7. Can I have multiple GST registrations under one PAN? Generally, a single registration per state is required for a business entity under one PAN. However, if you have distinct business verticals within a state, you may obtain separate registrations. Also, if you have branches in multiple states, you need separate GST registration for each state. Additionally, if you need to distribute common input service credit across multiple locations under the same PAN, separate ISD (Input Service Distributor) registration is mandatory from April 1, 2025.
8. How do I cancel my GST registration? You can apply for cancellation (Form GST REG-16) if your business closes, transfers, or your turnover falls below the threshold (for voluntary registrants after one year). A tax officer can also initiate cancellation for non-compliance (e.g., non-filing of returns for 6 consecutive months).
9. What is the GST rate for <a common item/service>? GST rates vary (0%, 5%, 12%, 18%, 28%) depending on the specific goods or service. You can find detailed rates using the HSN/SAC code finder on the CBIC website or refer to rate schedules. (Link to separate rate guide if available).
10. What is ARN / TRN / GSTIN?
    • TRN (Temporary Reference Number): Generated in Part A of the registration process, used to fill Part B. Valid for 15 days.
    • ARN (Application Reference Number): Generated after submitting the complete application (Part B), used to track the application status.
    • GSTIN (Goods and Services Tax Identification Number): The final 15-digit unique registration number issued upon approval.
11. What does ‘Pending for Clarification’ mean? It means the processing officer has reviewed your application and needs additional information or documents. You will receive a notice (Form GST REG-03) detailing the query, and you must reply within the specified time (usually 7 working days) using Form GST REG-04.
12. Can a GST application be rejected? Why? Yes, an application can be rejected (Form GST REG-05). Common reasons include failure to provide satisfactory clarification (reply to REG-03), discrepancies found during physical verification, submission of incorrect or fraudulent documents, or non-compliance with Aadhaar authentication / biometric authentication requirements.
