Why GST Registration is Essential for Your Business

Build credibility, unlock input tax credit, ensure compliance, and access new business opportunities.

GST registration is not only a legal requirement (once your turnover exceeds specified thresholds) but also a strategic advantage. Registered businesses benefit from:

Credibility and Trust

Build trust with customers and vendors. A valid GSTIN demonstrates that your business is legitimate and compliant with Indian tax laws.

Input Tax Credit

Collect GST and claim input tax credit on business purchases, reducing your overall tax liability and improving cash flow.

Legal Compliance

Stay compliant with the law and avoid penalties for non-registration. Meet mandatory requirements set by the government.

Business Opportunities

Easier onboarding with platforms and clients who require a valid GSTIN. Open doors to B2B and e-commerce opportunities.

Key Benefits of GST Registration

Online Filing & Management

Complete registration process online and manage returns through GST portal with ease.

Streamlined Documentation

Simple document requirements with Aadhaar authentication for faster processing.

Legal Protection

Protection against delayed payments under MSMED Act with compound interest provisions.

Fast Processing

Get your GSTIN in 7-10 days with our expert guidance and document support.

Easy Amendments

Update your business information anytime through the GST portal as your business grows.

Market Access

Essential for selling on e-commerce platforms and conducting inter-state business.

Important to Know

Understanding GST registration requirements helps you make informed decisions for your business.

  • Threshold Limits: Registration mandatory when turnover exceeds ₹40 lakh (goods) or ₹20 lakh (services) in normal states.
  • Compulsory Registration: Required for inter-state supplies, e-commerce sellers, and reverse charge mechanism regardless of turnover.
  • Processing Time: Typically 7-10 working days from submission with complete and accurate documents.

Who Needs GST Registration?

You must register for GST if your turnover crosses ₹20 lakh (services) or ₹40 lakh (goods), or if you fall under compulsory registration categories such as inter-state supply, e-commerce sellers, or reverse charge mechanism.

1. Threshold-based Registration (Section 22)

You're liable to register when your aggregate turnover (PAN-level, all-India) in a financial year exceeds the applicable threshold. For example: ₹40 lakh for goods or ₹20 lakh for services in normal states.

CategoryNormal States/UTsSpecial Category States
Supply of Goods₹40 lakh₹20 lakh
Supply of Services₹20 lakh₹10 lakh

Special Category States (SCS): Arunachal Pradesh, Assam, Himachal Pradesh, Jammu & Kashmir, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand. Always check the operative threshold for the State where you supply.

Note: Turnover includes taxable + exempt sales, exports, and inter-state supplies. GST/cess is excluded. Threshold is always calculated PAN-wise (not per branch).

2. Compulsory Registration—Irrespective of Turnover (Section 24)

Even if you don't cross the threshold, you must register if you fall into any of these categories. We've grouped them into 3 parts for clarity:

A. Cases where you MUST register because of what you sell

Product/Service-based requirements

  • Online supplies from outside India
  • OIDAR services (online information & database access/retrieval)
  • Notified services under RCM (reverse charge mechanism)
  • Inter-State taxable supply (goods suppliers generally require registration)

B. Cases where you MUST register because of where you operate

Location-based requirements

C. Cases where you MUST register because of how you sell

Sales channel-based requirements

WeeDoo Tip: If you operate as a CTP/NRTP (common for fairs, pop-ups, short-term projects), we can help you set up the right registration type and validity period.

3. Inter-State Supply: The Practical Rule

Historically, inter-State taxable suppliers had to register regardless of turnover. Today, service providers making inter-State supplies can claim the normal threshold exemption (₹20 lakh/₹10 lakh) but goods suppliers generally should assume registration is required unless covered by a specific notification or procedure.

We'll assess your fact pattern (goods vs. services; notified relaxations) before advising.

4. Selling Through E-commerce Operators (ECOs)

The rules distinguish operators from sellers. We break this into two client groups:

  • E-commerce Operators (Marketplaces)
    Must register and comply with TCS and other obligations.
  • Sellers selling on Amazon/Flipkart, etc.
    • General rule: Registration is compulsory regardless of turnover except where notified otherwise
    • Key relaxation for goods sellers (Notification 34/2023): If you only sell within one State/UT, do not make inter-State supplies, and meet specified conditions, you may sell goods via ECOs without GST registration (an enrolment facility exists for unregistered sellers). Effective 1 Oct 2023
    Example: If you sell home decor products on Flipkart, you normally need GST unless you qualify for the new exemption (single-State seller with no inter-State supplies).
  • Service providers working through apps (Ola, Uber, Zomato)
    • Notified services under Section 9(5) (e.g., passenger transport, accommodation, restaurant, housekeeping): the ECO pays the tax, and small service providers can rely on threshold exemption—registration is not forced just because the sale is through an ECO
    Example: If you drive an Ola cab, GST is paid by Ola on your behalf, you don't need a GST registration.
WeeDoo will check: If you qualify for the 34/2023 relief (single-State, no inter-State supplies) or fall under Section 9(5) services so you don't register unnecessarily.

5. Who Does NOT Need GST Registration? (Section 23)

You may not need GST registration if you fall into one of these categories:

  • Persons exclusively supplying exempt goods/services (fresh fruits, vegetables, bread, etc.)
  • Agriculturists (to the extent of produce from cultivation of land, e.g. farmers selling their own produce)
  • Persons specifically exempted by notification (e.g. small sellers on Amazon who meet Notification 34/2023 conditions)

6. Other Edge Cases WeeDoo Checks

  • Interest income: (e.g. bank interest) is exempt, but it still counts in aggregate turnover when deciding if you breach the threshold.
    Example: If you earned ₹50,000 bank interest, it won't be taxed but it counts toward total turnover when checking threshold.
  • Job-work scenarios: Job-worked goods generally count in the principal's turnover, not the job worker's.
    Example: If you do stitching or manufacturing job-work for another company, their turnover counts, not yours.
  • State-by-State options: Some States opted for the ₹40 lakh goods threshold at different times—use our checker if you operate in SCS or border cases.
    Example: Some Special Category States use ₹10 lakh threshold.

Quick Decision Guide

If you cross turnover, sell online, supply goods inter-state, or fall under special categories, you need GST.

You likely need GST registration if any of these is true:

  • Your annual turnover exceeds ₹40 lakh (goods) or ₹20 lakh (services).
  • You make inter-state taxable supplies.
  • You sell on e-commerce platforms like Amazon, Flipkart, or Zomato.
  • You operate as CTP/NRTP, or deal with RCM, TDS, or online services from outside India.

You may NOT need registration if:

  • You deal only in exempt supplies, are an agriculturist, or you qualify under specific exemption notifications.
Example: If you only sell home decor through Instagram within your state and turnover is below ₹40 lakh, you likely don't need GST.

Our End-to-End GST Registration Process

Here's how we work with you to register for GST, step by step.

1

Eligibility & Structure Review

We assess your business turnover (₹20 lakh for services / ₹40 lakh for goods / ₹10 lakh in special category states), state-wise operations, business constitution (sole proprietor, LLP, private company, etc.) and decide whether registration is mandatory or voluntary.

2

Document Preparation

We guide you through gathering the required documents:

  • PAN of business/applicant
  • Aadhaar (must be linked to mobile for authentication)
  • Identity and address proof of promoters or authorised signatory (self-attested)
  • Proof of place of business (ownership or rent agreement + utility bills)
  • Bank account proof
3

Online Application Filing

We handle the complete GST REG-01 filing process:

  • Part A: We log into the official GST portal and initiate Form GST REG-01 (entering legal entity name, PAN, mobile number, email).

  • Part B: Using the TRN, we complete the application — business details, place of business, partners/directors, bank details, upload documents.

If Aadhaar authentication fails, the application will go to manual verification, which may delay approval.

Frequently Asked Questions

GST registration is the process of obtaining a unique Goods and Services Tax Identification Number (GSTIN) from the government. This 15-digit number identifies your business for tax purposes and is mandatory once you cross certain turnover thresholds or fall into specific business categories.

Who must register for GST?

You must register for GST if:

  • Your annual turnover exceeds ₹40 lakh (goods) or ₹20 lakh (services) in normal states

  • You make inter-State taxable supplies
  • You are an e-commerce operator or seller through e-commerce platforms
  • You are liable to pay tax under reverse charge mechanism
  • You are a non-resident or casual taxable person

What documents are required for GST registration?

Essential documents include:

  • PAN card of the business/applicant
  • Aadhaar card of proprietor/partners/directors
  • Business registration proof (if applicable)
  • Proof of business address (rent agreement or ownership documents)
  • Bank account details and cancelled cheque
  • Photographs of proprietor/partners/directors
  • Digital Signature Certificate (for companies and LLPs)
How much does GST registration cost?

WeeDoo charges a service fee of ₹4,999 + GST for GST registration. This includes document verification, application filing, follow-up with authorities, and obtaining your GSTIN certificate. There are no hidden charges.

Note: The government does not charge any fee for GST registration itself.

Is GST registration free from the government?

Yes, the government does not charge any fee for GST registration. However, professional service providers like WeeDoo charge for their expertise in preparing documents, filing applications correctly, and ensuring quick approval.

Can I register for GST voluntarily if I'm below the threshold?

Yes, you can opt for voluntary GST registration even if your turnover is below the threshold limits. This is beneficial if you want to claim input tax credit, enhance business credibility, or deal with registered businesses who prefer GST-compliant vendors.

What is the penalty for not registering for GST?

If you fail to register for GST when required, you may face:

  • Penalty of 10% of the tax due (minimum ₹10,000)
  • Interest on unpaid tax at 18% per annum
  • Prosecution under certain circumstances
  • Inability to collect GST from customers or claim input tax credit
What is a GSTIN and what does it look like?

GSTIN (Goods and Services Tax Identification Number) is a unique 15-digit number assigned to every GST-registered business. The format is:

  • First 2 digits: State code
  • Next 10 digits: PAN of the business
  • 13th digit: Entity code (number of registrations in the state)
  • 14th digit: Z (default)
  • 15th digit: Check code

Example: 27AAPFU0939F1Z5 (Maharashtra-based business)

Do I need separate GST registration for multiple states?

Yes, GST registration is state-specific. If you have business operations in multiple states, you need to obtain separate GSTIN for each state. Each state registration will have the same PAN but different state codes.

What is the difference between GSTIN and PAN?

PAN (Permanent Account Number) is a 10-digit unique identifier issued by the Income Tax Department for tax purposes. GSTIN is a 15-digit number that includes your PAN within it (characters 3-12). While PAN is for income tax, GSTIN is specifically for GST compliance.

Can sole proprietors register for GST?

Yes, sole proprietors can and must register for GST if their annual turnover crosses the threshold limits. Sole proprietors need their individual PAN, Aadhaar, business address proof, and bank account details for registration.

Do I need GST registration to sell on e-commerce platforms like Amazon or Flipkart?

Generally, yes. Most e-commerce sellers need GST registration regardless of turnover. However, there are exceptions:

  • Goods sellers: If you sell goods only within one state (no inter-state sales) and meet conditions under Notification 34/2023, you may not need registration
  • Service providers: For notified services under Section 9(5) (accommodation, restaurant, transport), small providers may claim threshold exemption

WeeDoo can assess your specific situation and advise on registration requirements.

What is a Casual Taxable Person (CTP)?

A Casual Taxable Person is someone who occasionally undertakes taxable supplies in a state where they don't have a fixed place of business. Examples include exhibitions, fairs, or short-term projects. CTPs must register before starting business and the registration is valid for a maximum of 90 days.

What is a Non-Resident Taxable Person (NRTP)?

An NRTP is a person who occasionally undertakes taxable supplies in India but doesn't have a fixed place of business or residence in India. NRTPs must obtain GST registration before starting operations, which is valid for up to 90 days and can be extended.

What is the Composition Scheme under GST?

The Composition Scheme is a simplified GST compliance option for small businesses with turnover up to ₹1.5 crore (₹75 lakh for certain states). Under this scheme:

  • You pay tax at lower rates (1-5% depending on business type)
  • File returns quarterly instead of monthly
  • Cannot claim input tax credit
  • Cannot make inter-state supplies
  • Cannot sell through e-commerce platforms
Can I cancel my GST registration?

Yes, you can apply for GST cancellation if:

  • You close your business
  • Your turnover falls below the threshold and you want to cancel voluntary registration
  • You transfer your business
  • You're no longer liable to be registered

You can apply for cancellation through the GST portal by filing Form GST REG-16. The department will process it and issue a cancellation order (Form GST REG-19).

What happens after I receive my GSTIN?

Once you receive your GSTIN, you must:

  • Display your GSTIN on invoices, business premises, and website
  • File GST returns regularly (monthly/quarterly depending on your scheme)
  • Collect GST from customers and deposit it to the government
  • Maintain proper books of accounts and records
  • Issue GST-compliant tax invoices

WeeDoo provides post-registration support to help you stay compliant.

What is Form GST REG-01?

Form GST REG-01 is the application form for new GST registration. It has two parts:

  • Part A: Basic details (PAN, mobile, email) - generates TRN after OTP verification
  • Part B: Complete business details, promoter information, business addresses, bank details, and document uploads
What is TRN in GST registration?

TRN (Temporary Reference Number) is a 15-digit number generated after submitting Part A of Form GST REG-01. You use this TRN to complete Part B of the application within 15 days. The TRN is valid for 15 days from the date of generation.

What is ARN in GST registration?

ARN (Application Reference Number) is generated after you submit the complete GST registration application (Part B). You can track your application status using this ARN. The GST department uses this number to process your application and issue the GSTIN.

Can I track my GST registration application status?

Yes, you can track your application status on the GST portal using your ARN (Application Reference Number). WeeDoo also provides regular updates on your application status via email and SMS throughout the process.

What is the difference between CGST, SGST, and IGST?

These are components of GST:

  • CGST (Central GST): Collected by the Central Government on intra-state supplies
  • SGST (State GST): Collected by the State Government on intra-state supplies
  • IGST (Integrated GST): Collected by the Central Government on inter-state supplies, imports, and exports

Example: On a ₹100 intra-state supply with 18% GST, you charge ₹9 CGST + ₹9 SGST. For inter-state supply, you charge ₹18 IGST.

Do I need Aadhaar for GST registration?

Yes, Aadhaar authentication is mandatory for GST registration. The Aadhaar of the proprietor (for sole proprietorship) or all partners/directors (for partnerships/companies) must be authenticated during the registration process. Aadhaar must be linked with your mobile number for OTP verification.

Can NRIs or foreign nationals register for GST in India?

Yes, NRIs and foreign nationals can register for GST in India if they undertake taxable business activities. They need to register as Non-Resident Taxable Persons (NRTP) and provide:

  • Passport copy
  • Photograph
  • Proof of business place in India
  • Letter of Authorization
  • Advance tax deposit
What is the validity of GST registration?

Regular GST registration is permanent and valid until you apply for cancellation or the department cancels it for non-compliance. However, registration for Casual Taxable Persons (CTP) and Non-Resident Taxable Persons (NRTP) is valid for a specified period (maximum 90 days, extendable).
