01
What is GST Registration?
GST registration is the process of obtaining a GSTIN, a unique Goods and Services Tax Identification Number, for a business in India. A business may need GST registration when it crosses the applicable turnover limit or falls under compulsory registration categories such as specified inter-State taxable supplies where no exemption applies, persons required to pay tax under reverse charge, e-commerce-related cases, casual taxable persons or other specified GST cases.
GetMyCA supports the complete GST registration process, including document checking, online application filing, ARN tracking, GST officer clarification response and post-registration compliance guidance.
02
Who Needs GST Registration in India?
GST registration may be required for businesses that cross the applicable turnover threshold or fall under compulsory registration categories under GST law. The requirement depends on total turnover, state, business model, nature of supply and whether the business sells goods, provides services, sells online or operates across states.
GST registration liability is primarily governed by CGST Act Section 22 and CGST Act Section 24, along with applicable notifications, exemptions and state-specific provisions.
03
GST Registration Limit and Turnover Threshold
The GST registration limit depends on business type, state and nature of supply. A simple Rs. 20 lakh rule is not enough because GST has different threshold rules and compulsory registration cases. Total turnover, called aggregate turnover under GST law, should be checked along with state-specific limits and business activity.
GST registration requirement should be checked based on exact business model, turnover, state and supply type. GetMyCA reviews the facts before filing so that incorrect or unnecessary applications can be avoided.
04
Compulsory GST Registration Cases
Compulsory GST registration applies in specific cases even if the normal turnover threshold is not crossed. Many small businesses assume GST is required only after a turnover limit, but GST law also covers special situations where registration may be required earlier.
- ✓Specified inter-State taxable supplies, where no applicable exemption or notification applies
- ✓Casual taxable person
- ✓Persons required to pay tax under reverse charge
- ✓Non-resident taxable person
- ✓Input Service Distributor
- ✓E-commerce operator-related cases
- ✓Persons supplying through specified e-commerce models, where applicable
- ✓Agents of suppliers, where applicable
- ✓Other persons notified under GST law
Official reference: CGST Act Section 24 - compulsory registration categories.
05
GST Registration for Proprietorship, Firm, LLP and Company
GST registration documents and filing details change based on the business constitution. A proprietorship has different requirements from a company or LLP. Document review before filing helps avoid address, constitution and authorisation mistakes.

06
GST Registration for Ecommerce Sellers and Online Businesses
E-commerce sellers and online businesses should check GST registration requirement based on their selling model, platform, state and type of supply. Marketplace sellers, D2C brands, Instagram sellers and online service providers may have different GST treatment, so the requirement should not be decided from turnover alone.
- ✓Marketplace sellers on platforms such as Amazon or Flipkart may need GST review before onboarding.
- ✓D2C brands selling through their own website should check turnover and supply model.
- ✓Service providers should check service threshold and compulsory registration rules.
- ✓Businesses selling in multiple states should review place of supply and state-wise GST requirements.
07
Documents Required for GST Registration
Documents required for GST registration depend on business type, ownership status of the business place and authorised signatory details. Wrong or incomplete documents are a common reason for GST registration clarification or delay.
08
Consent Letter for GST Registration
A consent letter for GST registration is generally used when the business premises is not owned by the applicant and the owner allows the business to use that address for GST registration. It is commonly relevant for home-based businesses, family-owned premises, rented premises without a formal rent agreement, co-working setups and additional places of business.
- ✓Owner name and signature
- ✓Complete property address
- ✓Applicant or business name
- ✓Clear permission statement
- ✓Date of consent
- ✓Supporting address proof such as electricity bill or property proof
Common mistakes include owner name mismatch, address mismatch, missing signature, no supporting electricity bill or unclear permission wording.
09
GST Registration Fees and Professional Charges
GST registration on the government portal does not generally require a separate government filing fee. If a business takes professional help, charges may apply based on entity type, document status, number of business places and clarification handling requirement.
Professional fees depend on entity type, number of places of business, document readiness and whether GST officer clarification is raised.
