To start a business in India, you need to get multiple registrations, and one of the most important tax-related compliances for eligible businesses is GST registration. Whether you run a trading business, offer professional services, manufacture goods or sell through online channels, knowing when and how to get GST registration can save you compliance problems down the track.

The good news is that the application can be filled online via the official GST portal. The process starts with the entry of basic details, verification of PAN, mobile number and email address and then filling the detailed GST registration application.

This guide provides a detailed explanation of the GST online application in 2026 in simple language. It covers the process, documents, fees, GST number, certificate and application status.

What Is GST Registration?

GST registration is the procedure by which a qualifying business or person registers under the Goods and Services Tax regime.

Once the registration is completed successfully the taxpayer is provided with a unique GSTIN (Goods and Services Tax Identification Number).

The GSTIN is used for tax invoices, GST returns, communication with the tax authorities and other GST related activities.

GST registration is generally linked to the State or Union Territory where the taxpayer makes taxable supplies under the GST laws in force.

Who Needs GST Registration?

The GST registration is determined by many factors like turnover, nature of supply, business activity and other specific provisions of the GST Law.

In general, for many suppliers, the threshold under the CGST framework has been ₹20 lakh. In some cases, there have been different thresholds and provisions.. The law also permits higher thresholds for certain suppliers of goods subject to conditions and notifications.

There are also situations where registration may become necessary because of the nature of the business or activity.

For this reason, businesses should not decide eligibility only by looking at annual turnover.

A business should consider:

• Aggregate turnover

• Type of goods or services

• State of operation

• Inter-State supplies

• E-commerce activities

• Reverse charge situations

• Other provisions that may create registration liability

Businesses can also opt for voluntary registration where permitted.

GST Registration Online: Basic Process

The GST registration online process is completed through the GST common portal.

The broad process is:

Step 1: Visit the GST Portal

The applicant starts the registration application through the GST portal.

Step 2: Enter Basic Details

Part A of Form GST REG-01 requires details such as PAN, mobile number, email address and State/Union Territory. These details are verified electronically.

Step 3: Receive Temporary Reference Number

After successful verification, a temporary reference number is generated.

Keep this number safely because it can be useful for continuing the application.

Step 4: Complete Part B

The applicant provides business information and uploads the applicable documents.

Step 5: Verify and Submit

The application needs to be authenticated using the applicable electronic verification or digital signing method.

Step 6: Receive ARN

After successful filing, an Application Reference Number is generated. The GST portal sends acknowledgement information to the registered email and mobile number.

Step 7: Application Review

The application can be processed by the appropriate tax officer. If clarification or additional documents are required, the applicant may need to respond.

Step 8: GSTIN and Certificate

Once registration is approved, the GSTIN is assigned and the GST registration certificate becomes available electronically.

GST Registration Documents

One of the most important parts of the application is preparing the correct supporting documents.

The exact documents can differ depending on the constitution and nature of the business.

Common documents may include:

• PAN of the applicant/business

• Aadhaar details where applicable

• Proof of business constitution

• Photograph of proprietor/partners/promoters/directors as applicable

• Proof of principal place of business

• Bank account information as applicable

• Details of authorised signatory

• Letter of authorisation or board resolution where applicable

• Additional documents depending on business structure

For a rented property, businesses may need appropriate evidence of possession or use of the premises.

For an owned property, ownership-related proof may be used.

The GST registration application should be supported with documents that clearly establish the business and its place of operation.

GST Registration Fees

A common question is: How much does GST registration cost?

There is no government application fee for a normal GST registration application filed through the GST portal.

However, businesses may incur professional charges if they engage a consultant or tax professional to prepare and submit the application.

Therefore, it is useful to distinguish between:

Government registration fee: No fee for the normal GST registration application.

Professional service fee: Depends on the consultant or service provider.

If someone is helping with document preparation, application filing, clarification or follow-up, that service charge is separate from the GST portal process.

How to Apply for GST Number

Many business owners search for GST number apply because they want the number before starting invoicing.

The GSTIN is not simply purchased or manually generated by the applicant.

You first submit the registration application and complete the required verification.

After approval, the GSTIN is assigned by the GST system.

This is why applicants should not confuse GST registration with buying a GST number from a third-party website.

GST Registration Status Check

After filing the application, the applicant may want to know whether the registration is approved, pending or requires clarification.

The GST registration status can be checked using the application reference details available from the GST system.

The GST portal has a provision for tracking registration applications using the respective reference number. The GST system documentation also provides application status tracking after the temporary reference number/ARN stage.

Please keep the ARN safe until the registration process is completed.

Respond within the prescribed period if a notice or clarification is issued.

GST Registration Certificate

After approval, the taxpayer receives the GST registration certificate electronically.

The official GST taxpayer welcome material states that registered taxpayers receive the certificate in Form GST REG-06 and can download it from the GST portal. No physical certificate is issued by the government.

To download the certificate, taxpayers can log in and go through:

Services → User Services → View/Download Certificate

The certificate contains important registration details, including the GSTIN and principal place of business.

GST Registration Login

Once the registration process is complete, the taxpayer can sign in to the GST portal using the login credentials created for the account.

After first time login, new taxpayers can login with their GSTIN and password.

The GST portal also has the facility to retrieve forgotten user id or reset the password through OTP verification.

Make sure to keep the registered email and mobile number active as GST communications and OTPs can be sent through these channels.

How Long Does GST Registration Take?

The time it takes depends on the application and whether or not any clarification is required.

The GST registration rules have prescribed time limits for processing applications and responding to notices. In cases where there is a need for clarification under the applicable rules and the officer is satisfied with the response, registration may be granted within the prescribed period.

An application with complete and consistent information is easier to process than one with mismatched documents.

Common Reasons for GST Registration Delays

Some common issues include:

• Incorrect PAN details

• Address mismatch

• Unclear address proof

• Incorrect business constitution

• Missing authorised signatory information

• Document upload problems

• Incomplete application

• Failure to respond to a clarification

• Incorrect bank or business information

Before submission, check the entire application rather than focusing only on the GSTIN field.

Should a Small Business Take Voluntary GST Registration?

Some businesses below the relevant mandatory threshold may wish to register on a voluntary basis.

There may be commercial reasons for doing so but voluntary registration also attracts GST compliance obligations.

The FAQ of CBIC mentions that the tax liability applies from the relevant supplies after registration for a person who voluntarily registers as a normal taxable person.

Hence, voluntary registration should be done after knowing related return filing and tax obligations.

4. Address proof

5. Business premises documents
