Apply for GST Registration

GST registration is applied for entirely online through the official GST portal at gst.gov.in — no physical visit to any tax office is required. The process involves two parts: Part A, where you enter your PAN, mobile number, and email address to generate a Temporary Reference Number (TRN); and Part B, where you use the TRN to fill in complete business details, upload required documents, and submit the application using a Digital Signature Certificate (DSC) or Aadhaar-based Electronic Verification Code (EVC). On successful submission, you receive an Application Reference Number (ARN) to track your application until your GSTIN is issued.

Step 1: Visit gst.gov.in and navigate to Services, then Registration, then New Registration. Step 2: Select Taxpayer as the type, choose your state and district, enter your legal business name, PAN, email, and mobile number, then submit to receive OTPs on both. Step 3: Enter both OTPs to verify and receive your TRN. Step 4: Log back in with the TRN and complete Part B — filling in business details, promoter or partner information, authorised signatory details, principal place of business, any additional places of business, HSN or SAC codes for your goods or services, and bank account details. Step 5: Upload all required documents. Step 6: Submit using DSC (mandatory for companies and LLPs) or Aadhaar EVC (for proprietorships and partnerships). Step 7: Save the ARN for tracking. Your GSTIN is issued in Form GST REG-06 once the GST officer approves the application.

The documents required depend on your business constitution. For a sole proprietorship: PAN card and Aadhaar card of the owner, a passport-size photograph, proof of principal place of business such as an electricity bill, rent agreement, or property tax receipt, and a cancelled cheque or bank statement. For a private limited company or LLP: Certificate of Incorporation, MOA and AOA or LLP agreement, PAN and Aadhaar of all directors or designated partners, a board resolution or letter of authorisation for the signatory, and business address proof. For a partnership firm: partnership deed, PAN of the firm and all partners, and business address proof. All documents must be uploaded in PDF or JPEG format within the 1 MB per file size limit on the GST portal.

No, the Government of India charges absolutely no fee to apply for GST registration — the entire process on gst.gov.in is free of cost for all business types including proprietorships, partnerships, private limited companies, LLPs, and trusts. If you engage a chartered accountant, GST practitioner, or tax consultant to prepare and file the application on your behalf, their professional service fee typically ranges from Rs. 500 to Rs. 2,500 depending on your business structure and the state of registration.

If your application is complete and all documents are in order, GST registration is typically approved and your GSTIN is issued within 3 to 7 working days. If the assigned GST officer raises a Show Cause Notice (SCN) or requests additional documents or clarification, you must respond within 7 working days via the ARN on the portal, which can extend the total timeline to 15 to 30 days. Applications where the applicant does not respond within the stipulated time may be rejected, requiring a fresh registration application.

A Temporary Reference Number (TRN) is a 15-digit number generated after you complete Part A of the GST registration form. It allows you to save your progress and return to complete Part B within 15 days; after 15 days the TRN expires and you must restart Part A. An Application Reference Number (ARN) is a unique reference number generated after you successfully submit the complete application covering both Part A and Part B. The ARN is used to track your application status on the GST portal under Services, then Registration, then Track Application Status — and is valid until the application is approved, rejected, or withdrawn.

Any individual or entity carrying out a taxable supply of goods or services in India is eligible to apply for GST registration. Mandatory registration applies when aggregate annual turnover crosses Rs. 40 lakh for goods or Rs. 20 lakh for services in normal category states, or Rs. 20 lakh for goods and Rs. 10 lakh for services in special category states such as Manipur, Mizoram, Nagaland, and Tripura. Irrespective of turnover, mandatory registration applies to e-commerce sellers, interstate suppliers, importers, exporters, casual taxable persons, non-resident taxable persons, input service distributors, and businesses liable to pay tax under the reverse charge mechanism. Any business below the threshold may also register voluntarily.

Yes, individuals, sole proprietors, and partners in a partnership firm can verify and submit their GST registration application using Aadhaar-based OTP authentication (EVC) without a Digital Signature Certificate. For private limited companies, public limited companies, and LLPs, a valid Class 3 Digital Signature Certificate (DSC) of the authorised director or partner is mandatory for submission. Aadhaar-authenticated applications are generally processed faster — typically within 3 working days — without requiring a physical site verification by the GST officer, whereas non-Aadhaar applications may be subject to field inspection before final approval.

HSN (Harmonised System of Nomenclature) codes classify goods under GST, and SAC (Services Accounting Codes) classify services. You must declare the correct HSN or SAC codes for your primary goods or services in Part B of the registration form under the Goods and Services section. These codes determine the applicable GST rate for your products or services and are mandatory on all tax invoices issued after registration. Businesses with aggregate turnover below Rs. 5 crore must quote 4-digit HSN codes on invoices; those above Rs. 5 crore must use 6-digit codes. Selecting an incorrect code can lead to wrong tax rates on invoices and compliance issues during GST audits.

The most common reasons for a GST registration query or rejection include: a mismatch between the name on PAN and the legal name entered in the application; blurry, incomplete, or incorrect documents uploaded; business address proof that does not match the address entered in the form; absence of a landlord No Objection Certificate or ownership proof for rented premises; failure to respond to the officer's query within 7 working days; Aadhaar details not matching PAN records; selecting the wrong business constitution type; and not declaring all directors or partners correctly. Cross-checking all entries against original documents and uploading clear, legible scans reduces the risk of delay significantly.

Yes, a residential address can be declared as the principal place of business when applying for GST registration, which is common for freelancers, home-based sellers, online tutors, and consultants. You must provide valid address proof for the residential premises such as an electricity bill, water bill, or bank statement in your name. If the property is rented, you need to submit a rent agreement together with the landlord's No Objection Certificate (NOC) and their ownership proof such as a property tax receipt or registered sale deed. Using a home address does not affect the validity or type of GSTIN issued.

You can track your GST registration application at any time using your ARN on the GST portal. Visit gst.gov.in, click on Services, then Registration, then Track Application Status, and enter your ARN. The status will display as one of the following: Pending for Processing (the application is with the GST officer and no action is needed from you), Pending for Clarification (the officer has raised a query and you must respond within 7 working days by logging into the portal with your ARN), Clarification Filed (your response has been submitted and is back with the officer), Approved (GSTIN has been issued and the registration certificate is available for download), or Rejected (with reasons stated, allowing you to file a fresh application). Email and SMS notifications are also sent to your registered contact details at each stage.

For mandatory registration, the effective date is the date on which the business first became liable to register — typically the date its aggregate turnover crossed the applicable threshold — provided the application is filed within 30 days of that date. If the application is submitted after the 30-day window, the effective date becomes the date of submission of the application, not the date of liability. For voluntary registration, the effective date is always the date the application is submitted. The effective date is printed on the GST registration certificate and determines from which date GST-compliant invoices must be issued and returns must be filed.

Yes, if your business has offices, branches, warehouses, or any other place of business in more than one state, you must apply for a separate GST registration in each of those states. GST is a state-level registration, and each approved registration results in a distinct 15-digit GSTIN bearing the two-digit state code of the respective state as the first two characters. A single PAN can hold multiple GSTINs across different states. Each state-wise registration is applied for separately on the GST portal following the same process, with address proof and relevant documents specific to the place of business in that state.

Once approved, your 15-digit GSTIN is generated and a GST Registration Certificate in Form GST REG-06 is issued, which you can download from the GST portal under Services, then User Services, then View or Download Certificates. You must display this certificate prominently at your principal place of business and all additional places of business. From the effective date of registration, you are required to issue GST-compliant tax invoices for all taxable supplies, collect and remit the applicable GST, file GSTR-1 and GSTR-3B returns monthly or quarterly, pay GST dues by the prescribed due dates, and maintain GST-compliant books of accounts for a minimum of 6 years.

Failing to apply for GST registration within 30 days of becoming liable attracts a penalty of Rs. 10,000 or 10% of the tax amount due — whichever is higher — along with interest at 18% per annum on the unpaid tax from the date it first became payable. In cases of deliberate suppression of turnover to evade registration, the penalty can equal 100% of the tax evaded. Operating without registration also means you cannot issue valid GST tax invoices for the unregistered period, and any buyers who purchased from you during that time are ineligible to claim input tax credit on those purchases.
