How to Register GST in India: Complete Step-by-Step Guide

Starting a business and wondering how to register GST online in India?

GST registration is an important compliance requirement for businesses that cross the applicable turnover limit or fall under specified categories requiring compulsory registration.

The registration process is completed online through the GST Portal. However, before submitting an application, the applicant should correctly determine:

• Whether GST registration is required
• The state in which registration should be obtained
• The legal constitution of the business
• Whether to choose the regular or composition scheme
• The correct business activities
• The appropriate HSN or SAC codes
• The principal place of business
• The authorised signatory
• The documents required for the premises
• Whether Aadhaar or biometric authentication will apply

Incorrect details or incomplete documents may lead to a clarification notice, physical verification, delay or rejection of the application.

This guide explains how to register GST, the documents required, the complete GST Portal process and the important precautions to take before applying.

What Is GST Registration?

GST registration is the process through which a person or business is registered under the Goods and Services Tax framework.

After approval, the applicant is allotted a Goods and Services Tax Identification Number, commonly known as GSTIN.

A GSTIN is a state-specific registration number. A business operating from more than one state may therefore require separate GST registrations depending on the locations from which taxable supplies are made.

Once registered, the taxpayer may be required to:

• Issue GST-compliant invoices
• Charge applicable GST
• Maintain prescribed books and records
• File GST returns
• Pay collected tax
• Reconcile input tax credit
• Update registration details when changes occur
• Display the GST registration certificate and GSTIN as prescribed

GST registration should therefore not be obtained merely for having a GST number. The recurring compliance responsibilities should also be understood before applying.

Who Is Required to Register under GST?

GST registration applicability depends on several factors, including:

• Aggregate turnover
• Nature of goods or services
• State of operation
• Interstate transactions
• E-commerce activities
• Reverse-charge liability
• Whether the person is a casual taxable person
• Whether supplies are taxable or exempt
• Whether any statutory exemption applies

The CGST Act contains separate provisions for persons liable for registration, persons not liable and categories requiring compulsory registration. ([India Code][1])

GST Registration Based on Turnover

The commonly applicable registration threshold for service providers is generally ₹20 lakh of aggregate turnover, subject to lower limits and state-specific provisions.

For persons engaged exclusively in supplying goods, the threshold may be ₹40 lakh in eligible states, provided the applicant is not covered by compulsory-registration provisions, excluded goods or specified states and territories. Notification No. 10/2019 specifically provides the ₹40 lakh exemption subject to listed conditions and exclusions.

The applicable limit should not be selected solely by looking at whether the business sells goods or services.

You should also review:

• State of operation
• Nature of supplies
• Whether both goods and services are supplied
• Compulsory-registration provisions
• Notifications applicable to the business
• All-India aggregate turnover under the same PAN

What Is Aggregate Turnover?

Aggregate turnover is broadly calculated on an all-India PAN basis.

This means that where the same person operates businesses or branches under one PAN in different states, their turnover may need to be considered together for checking the registration threshold.

It may include:

• Taxable supplies
• Exempt supplies
• Export supplies
• Interstate supplies
• Supplies made by different business locations under the same PAN

The exact calculation should be examined according to the applicable GST definition and facts of the business.

Businesses That May Require Compulsory Registration

Certain categories may require registration irrespective of the normal turnover threshold, subject to statutory exemptions and notifications.

Examples may include:

• Persons liable to pay tax under specified reverse-charge provisions
• Casual taxable persons
• Non-resident taxable persons
• Tax deductors and tax collectors
• Input Service Distributors
• Persons making specified supplies through e-commerce operators
• Agents supplying on behalf of taxable persons
• Other persons notified under GST law

Compulsory registration has several exceptions and notifications. For example, the treatment of interstate services, e-commerce sellers and persons making supplies subject to reverse charge may differ depending on the transaction.

A professional applicability review is advisable before concluding that registration is compulsory.

Persons Dealing Exclusively in Exempt Supplies

A person dealing exclusively in goods or services that are wholly exempt or not liable to GST may generally not be required to register merely because turnover crosses the normal threshold.

The CBIC registration FAQs distinguish businesses making exclusively exempt supplies from businesses making taxable supplies. ([CBIC GST][2])

However, a business making a combination of exempt and taxable supplies should separately examine its aggregate turnover and registration liability.

Can You Register for GST Voluntarily?

A person whose turnover is below the applicable threshold may choose voluntary GST registration.

Voluntary registration may be considered where:

• Business customers require a GST invoice
• Customers want to claim input tax credit
• The business deals mainly with registered entities
• The business wants to expand across B2B markets
• Online platforms or tenders require GST details
• The business expects to cross the limit shortly
• The business wants a formal tax identity

After obtaining voluntary registration, the person is generally treated as a registered taxpayer and must comply with the applicable invoicing, tax-payment and return-filing requirements.

Therefore, voluntary registration should be selected only after understanding its ongoing compliance cost and responsibilities.

When Should You Apply for GST Registration?

A person who becomes liable for GST registration should generally apply within 30 days from the date on which the registration liability arises.

The GST Portal guidance states that where a normal taxpayer applies within 30 days, registration may be effective from the date of liability. In delayed applications, the effective date may be the date on which registration is granted, although the original tax liability may still require separate examination. ([GST Portal][3])

Do not wait until the first GST return is due before checking registration applicability.

The liability date may affect:

• GST payable on earlier invoices
• Invoice correction
• Input tax credit
• Customer documentation
• Interest exposure
• Effective date of registration
• Compliance for the intervening period

Information to Finalise Before Applying

Before opening the GST registration form, finalise the following information.

1. Legal Name of the Business

The legal name should match the PAN database.

For a proprietorship, GST registration is linked to the proprietor’s individual PAN, while the trade name may separately represent the business name.

For a partnership firm, LLP or company, the entity’s PAN and legal name should be used.

2. Trade Name

The trade name is the name under which the business operates publicly.

For example:

• Legal name: Hemant Garg
• Trade name: HG Business Solutions

The legal name and trade name may be different, but both should be entered correctly.

The GST Portal separately recognises the legal name and trade name in the registration application. ([GST Portal][3])

3. Constitution of Business

Select the correct constitution, such as:

• Proprietorship
• Partnership
• Hindu Undivided Family
• Private Limited Company
• Public Limited Company
• One Person Company
• LLP
• Trust
• Society
• Association of Persons
• Government entity
• Other applicable constitution

The constitution selected in the application is validated with PAN-related information. ([GST Portal][3])

4. State and District

GST registration is state-specific.

Select the state from which the business actually makes or proposes to make supplies.

Do not use an address merely because documents are easily available there if the business does not genuinely operate from that location.

5. Principal Place of Business

The principal place of business is the main business location in the relevant state.

It may be:

• Owned office
• Rented office
• Residential property
• Shared office
• Co-working space
• Warehouse
• Shop
• Factory
• Consent premises

The GST Portal describes the principal place as the primary location in the state where the business is conducted and where books and records are generally maintained. ([GST Portal][3])

6. Nature of Business Activity

The applicant may need to select one or more activities, such as:

• Supplier of services
• Retail business
• Wholesale business
• Factory or manufacturing
• Warehouse or depot
• Works contract
• Office or sale office
• Recipient of goods or services
• Leasing business
• Export
• Import
• Other applicable activity

Select activities according to the actual business model.

7. Goods and Services

Identify the principal goods or services that the business will supply.

The applicant should determine:

• Description of goods or services
• HSN code for goods
• SAC code for services
• Applicable GST rate
• Whether supplies are taxable, exempt or zero-rated

Incorrect classification at the registration stage may later affect invoicing and return filing.

8. Regular or Composition Scheme

Eligible small taxpayers may evaluate the composition scheme, but it is not suitable for every business.

Before selecting composition, review:

• Turnover eligibility
• Nature of goods and services
• Interstate transactions
• E-commerce activities
• Customer profile
• Input tax credit impact
• Restrictions on tax collection
• Applicable return and payment requirements

The GST Portal provides the composition option within the business-details section of the registration form. ([GST Portal][3])

Documents Required for GST Registration

The exact documents depend on the business constitution, promoters, authorised signatory and premises.

GST Registration Documents for a Proprietorship

A proprietorship may commonly require:

• PAN of the proprietor
• Aadhaar of the proprietor
• Photograph
• Mobile number
• Email address

Commonly required documents include:

For Consent or Shared Premises

Commonly required documents include:

• Consent letter or NOC
• Ownership proof of the consenting owner

Can GST Registration Be Obtained at a Residential Address?

A residential property may be used as the principal place of business where the business genuinely operates from that address and valid documents are available.

Common documents may include:

• Electricity bill
• Ownership proof
• Rent agreement, if rented
• Consent letter from the owner
• Owner’s NOC
• Identity documents

The applicant should also consider:

• Tenancy restrictions
• Housing-society rules
• Municipal requirements
• Nature of business
• Storage or customer movement
• Other local approvals

GST approval does not automatically override other local or contractual restrictions on commercial use of a property.

Can GST Registration Be Obtained at a Co-Working Space?

A co-working address may be used where the provider permits GST registration and supplies valid supporting documents.

Documents may include:

• Service or occupancy agreement
• NOC
• Electricity bill
• Ownership or lease-chain documents
• Letter confirming use of premises
• Details of the allocated workspace

Before paying for a co-working plan, confirm that the provider will support:

• GST registration
• Physical verification
• Receipt of departmental communication
• Display of business name
• Access during verification
• Address-related amendments

How to Register GST Online: Step-by-Step Process

The online GST registration application is broadly divided into Part A and Part B.

The official GST Portal manual confirms that the process starts through Services → Registration → New Registration and that the form is divided into these two parts. ([GST Portal][3])

Step 1: Open the GST Portal

Go to the official GST Portal and select:

Services → Registration → New Registration

Select “Taxpayer” as the applicant type for a normal taxpayer.

Step 2: Complete Part A of the Application

Enter:

• State or Union Territory
• District
• Legal name as per PAN
• PAN
• Email address
• Indian mobile number
• Captcha

The legal name should exactly match the PAN database.

Separate OTPs may be sent to the entered mobile number and email address for verification. ([GST Portal][3])

Step 3: Generate the TRN

After OTP verification, the portal generates a Temporary Reference Number, known as TRN.

The TRN is used to open and complete Part B of the application.

The portal displays the saved application and its expiry date. The official manual states that an unsubmitted draft and its TRN may be purged after 15 days. ([GST Portal][3])

Save the TRN securely and complete the application before expiry.

Step 4: Open Part B Using the TRN

Return to the New Registration page and select the TRN option.

Enter:

• TRN
• Captcha
• OTP

Open the saved application by selecting the edit option.

Step 5: Fill in Business Details

Enter or select:

• Trade name
• Additional trade names, if any
• Constitution of business
• District
• Composition option
• Date of commencement
• Date of liability
• Reason for registration
• Existing registrations, where applicable
• Business activity details

The information should match the PAN, incorporation documents and actual business setup.

Step 6: Add Promoter or Partner Details

Enter details of:

• Proprietor
• Partners
• Directors
• Karta
• Trustees
• Members
• Other promoters, as applicable

Information may include:

• Name
• Father’s name
• Date of birth
• PAN
• Aadhaar
• DIN, where applicable
• Mobile number
• Email
• Residential address
• Photograph
• Designation
• Citizenship details

The GST Portal allows stakeholder information according to the selected constitution and also requires photographs and identity details. ([GST Portal][3])

Step 7: Enter Authorised Signatory Details

The authorised signatory is the person permitted to:

• Sign the application
• Receive GST communications
• File returns
• Submit replies
• Operate the GST Portal account
• Complete authentication

Where the authorised signatory is not the proprietor, partner or director, upload appropriate authorisation.

This may include:

• Authorisation letter
• Board resolution
• Proof of appointment
• Photograph
• Identity documents

Step 8: Enter Principal Place of Business

Enter:

• Complete address
• PIN code
• District
• State and central jurisdiction
• Contact details
• Nature of possession
• Nature of business activities
• Address location on map
• Supporting documents

Ensure that the address in the form is consistent with the rent agreement, electricity bill and NOC.

Even small differences in:

• Floor number
• Plot number
• Sector
• Street
• PIN code
• Owner name
• Tenant name

can lead to a clarification request.

Step 9: Add Additional Places of Business

Add warehouses, branches, godowns, shops or offices operating within the same state, where applicable.

A location in another state cannot ordinarily be added merely as an additional place under the first state’s GST registration. A separate state registration may be required depending on the business operations.

Step 10: Add Goods and Services

Enter the principal goods or services supplied by the business.

Select accurate HSN or SAC classifications based on:

• Product description
• Nature of service
• Business model
• Contracts
• Invoices
• Applicable GST notifications

Avoid selecting unrelated codes merely because they appear similar.

Step 11: Complete State-Specific Information

Enter state-specific details wherever applicable, such as:

• Professional tax details
• State excise licence
• Other local registrations

The fields displayed depend on the state and type of applicant.

Step 12: Select Aadhaar Authentication

Select the appropriate option for Aadhaar authentication.

For new registrations, the portal may require:

• OTP-based Aadhaar authentication
• Biometric authentication at a GST Suvidha Kendra
• Photo capture
• Document verification
• Site verification

The process depends partly on system-generated risk parameters.

The GST Portal states that applicants selecting Aadhaar authentication may receive either an OTP-authentication link or a link to book a slot for biometric verification at a designated GST Suvidha Kendra. ([GST Portal][4])

Step 13: Verify and Submit the Application

Review every tab before submission.

Depending on the constitution, the application may be submitted through:

• Digital Signature Certificate
• Electronic Verification Code
• Aadhaar-based verification
• Other permitted authentication method

Companies and LLPs may require submission through a Digital Signature Certificate.

After successful submission, an Application Reference Number, or ARN, is generated and communicated to the registered mobile number and email. ([GST Portal][3])

Step 14: Track the Application

The status can be tracked through:

Services → Registration → Track Application Status

Use the ARN to check whether the application is:

• Pending for processing
• Pending for clarification
• Pending for authentication
• Approved
• Rejected
• Assigned for physical verification
• Awaiting applicant action

Check the registered email and mobile regularly after filing.

Step 15: Respond to a Clarification Notice

The GST officer may request clarification or additional documents where:

• Address documents are incomplete
• Rent agreement is invalid or unclear
• Owner’s NOC is missing
• Business activity is not explained
• HSN or SAC is inconsistent
• Authorised signatory documents are missing
• Name differs across records
• Photographs are unclear
• Premises cannot be verified
• The officer requires proof of business activity

A clarification reply should:

• Address every point separately
• Attach readable documents
• Explain any discrepancy
• Avoid unrelated documents
• Be filed within the permitted period
• Maintain consistency across the application

A vague or incomplete reply may lead to rejection.

Step 16: Complete Physical or Biometric Verification

Biometric Aadhaar authentication is not required for every applicant, but it may be applied based on risk parameters.

Where biometric verification is required:

• The selected promoter or partner may need to attend
• The primary authorised signatory may need to attend
• Original or specified documents may need verification
• Photograph and biometric details may be captured
• The process must be completed within the communicated period

The GST Portal states that failure to complete required biometric authentication or document verification within the available 15-day period may prevent generation of ARN or completion of the application. ([GST Portal][5])

Where Aadhaar authentication is not selected, the applicant may be required to visit a designated GST Suvidha Kendra for photo capture and document verification. ([GST Portal][4])

Step 17: Download the GST Registration Certificate

After approval, log in to the GST Portal and navigate to:

Services → User Services → View/Download Certificates

The approved GST registration certificate can be downloaded from this section. ([GST Portal][6])

The registration certificate is issued in Form GST REG-06. ([GST Portal][7])

Review the certificate carefully for:

• Legal name
• Trade name
• GSTIN
• Constitution
• Principal place
• Additional places
• Date of liability
• Effective date
• Registration type

Apply for amendment if an approved detail is incorrect or subsequently changes.

Is Bank Account Proof Mandatory at the Time of Registration?

Bank account details are not necessarily mandatory in the initial registration form.

The official GST Portal manual states that bank details were made optional for the initial application and may be added after grant of GSTIN through a non-core amendment. ([GST Portal][3])

After registration, the taxpayer may be prompted to provide bank details.

Common bank documents include:

• Cancelled cheque
• Bank statement
• Passbook
• Bank letter

The account name and PAN-linked business details should be consistent.

How Long Does GST Registration Take?

There is no single guaranteed approval period for every application.

Processing depends on:

• Aadhaar authentication
• Biometric requirement
• Risk parameters
• Completeness of documents
• Physical verification
• Clarification notice
• Officer review
• Portal processing
• Accuracy of premises details

A correctly prepared application may be processed without clarification, while an application involving verification or document discrepancies may take longer.

Avoid promotional claims guaranteeing registration within a fixed number of hours because final approval remains with the GST authority.

Common Reasons for GST Registration Rejection

1. Incorrect Legal Name

The legal name does not match the PAN database.

2. Wrong Business Constitution

For example, applying as a proprietorship using a partnership PAN or selecting an incorrect entity type.

3. Address Mismatch

The address in the application differs from the rent agreement, utility bill or ownership proof.

4. Invalid Rent Agreement

The agreement may be unsigned, expired, incomplete or not connected with the actual premises.

5. Missing Owner’s Consent

The property owner has not provided valid permission for use of the address.

6. Unclear Electricity Bill

The bill is old, unreadable or relates to a different property.

7. Incorrect HSN or SAC

The selected goods or services do not match the business description.

8. Incomplete Authorisation

The authorised signatory does not have a proper authorisation letter or Board resolution.

9. Aadhaar Authentication Failure

The Aadhaar name, date of birth, mobile number or identity information may not match.

10. Failure to Attend Verification

The applicant fails to complete biometric or physical verification within the provided period.

11. Unclear Business Activity

The application does not properly explain how the proposed business will operate.

12. Multiple Inconsistent Documents

Different business names, floor numbers, addresses or owner names appear across the submitted papers.

What to Do Immediately after Getting GST Registration

Receiving a GSTIN is only the beginning of GST compliance.

After registration:

Download the Registration Certificate

Check all approved details and save a copy.

Display GSTIN and Certificate

Display the registration certificate and GSTIN according to the applicable requirements.

Add Bank Details

Update the bank account through the GST Portal where required.

Prepare a GST-Compliant Invoice

The invoice may need to contain:

• Supplier name
• Address
• GSTIN
• Invoice number
• Invoice date
• Customer details
• Place of supply
• HSN or SAC
• Taxable value
• GST rate
• CGST and SGST or IGST
• Total invoice value
• Reverse-charge indication, where applicable
• Other prescribed particulars

Select the Correct GST Rate

Do not select the rate merely by looking at competitors’ invoices.

Review the applicable:

• HSN or SAC
• Rate notification
• Exemption notification
• Place-of-supply provisions
• Reverse-charge provisions

Set Up Accounting Ledgers

Create separate ledgers for:

• Output CGST
• Output SGST
• Output IGST
• Input CGST
• Input SGST
• Input IGST
• Reverse-charge liability
• GST payable
• Electronic cash ledger payments

Understand Your Return Frequency

Depending on the registration and scheme, the taxpayer may need to file:

• GSTR-1
• GSTR-3B
• Quarterly returns under QRMP
• Composition statements
• Annual returns
• Other applicable forms

Reconcile Input Tax Credit

Purchase invoices should be reconciled with available GST data before claiming credit.

Review E-Invoice and E-Way Bill Applicability

Depending on turnover, nature of goods and transactions, additional compliance may apply.

Keep Registration Details Updated

Apply for amendment when there is a change in:

• Trade name
• Business address
• Partners
• Directors
• Authorised signatory
• Contact details
• Bank account
• Business activity
• Goods or services
• Additional business location

Regular GST Registration vs Composition Scheme

Regular Scheme

Under regular registration, a taxpayer may generally:

• Charge applicable GST
• Claim eligible input tax credit
• Make interstate taxable supplies subject to law
• Issue tax invoices
• File regular GST returns

Composition Scheme

The composition scheme may offer simplified compliance for eligible taxpayers, but it also carries restrictions.

A composition taxpayer may face limitations relating to:

• Collection of tax
• Input tax credit
• Interstate outward supplies
• E-commerce transactions
• Type of activity
• Invoice format
• Display requirements

A B2B business may prefer the regular scheme because customers commonly expect tax invoices and input tax credit.

The decision should be made according to the customer profile, margins, purchase pattern and expected growth rather than only the apparent tax rate.

Can a Freelancer Register for GST?

Yes. A freelancer may obtain GST registration voluntarily or where legally required.

Applicability may depend on:

• Aggregate turnover
• Nature of services
• Location of clients
• Export of services
• E-commerce platform
• Reverse-charge provisions
• Other business activities under the same PAN

Freelancers serving overseas clients should separately review:

• Export-of-service conditions
• Place of supply
• Receipt in permitted foreign currency
• LUT
• GST return reporting
• Foreign remittance documents

Having a foreign client does not automatically make every service an export.

Can an E-Commerce Seller Register for GST?

Yes. E-commerce sellers may require GST registration depending on:

• Platform
• Type of goods or services
• State of inventory
• Warehouse locations
• Turnover
• Interstate sales
• E-commerce operator provisions
• Applicable registration exemptions
• Tax-collection provisions

Recent notifications have created conditional relief for certain small sellers, so the older general assumption that every online seller must always register should not be applied without reviewing the current facts.

Can You Have More Than One GST Registration?

A person may have:

• Separate GST registrations in different states
• Multiple registrations in the same state where permitted and chosen
• Separate registration for an SEZ unit
• Additional places of business under an existing state GSTIN

Each GSTIN may have separate:

• Returns
• Tax ledgers
• Invoices
• Reconciliations
• Compliance obligations

Before obtaining multiple registrations, evaluate the administrative and accounting impact.

A commercial office is not always compulsory. A residential, rented, consent or co-working address may be used where the business genuinely operates and valid documents are available.

Is a rent agreement compulsory?

A rent or lease agreement is commonly required where the premises are rented. Other premises may require ownership proof or a consent letter with the owner’s supporting documents.

Is an NOC required for GST registration?

An NOC or consent letter is generally useful where the applicant is not the owner or where the agreement does not independently establish permission to use the property for business.

Can I use my home address for GST?

Yes, subject to proper address documents, owner consent where required and other local or contractual restrictions.

Is Aadhaar authentication compulsory?

New registration applications generally involve Aadhaar authentication or an alternative verification process. The applicant may be selected for OTP-based or biometric authentication depending on the portal process and risk parameters. ([GST Portal][4])

What is TRN in GST registration?

TRN means Temporary Reference Number. It is generated after completion of Part A and is used to access and complete Part B.

How long is TRN valid?

Bank details are presently optional at the initial registration stage and may be added after GSTIN is granted. ([GST Portal][3])

Can I charge GST immediately after applying?

Mere submission of an application does not always mean that a GSTIN has been granted. The effective date, date of liability and invoicing treatment should be reviewed according to the facts.

A separate registration may be required where the business has a place of supply operations or establishment from which taxable supplies are made in another state.

Can I cancel GST registration later?

Yes, an eligible taxpayer may apply for cancellation, subject to pending returns, tax liabilities, stock or input tax credit implications and other applicable conditions.

Can I change my address after registration?

Yes. An address change can generally be made through an amendment application with updated supporting documents.

How much time does GST registration take?

Processing time depends on documents, Aadhaar or biometric authentication, officer verification and whether clarification is raised. No fixed approval timeline should be guaranteed.

Should I take voluntary GST registration?

Voluntary registration may be useful for B2B businesses or businesses expecting growth, but it also creates ongoing return, tax and record-maintenance obligations.
