The goods and services tax (GST) revolutionized the indirect tax system in India. It subsumed multiple indirect state and central taxes and brought uniformity and integrity to the indirect tax system in the country. It aimed to simplify compliance, reduce the cascading effect of taxes on consumers, and eliminate tax evasion. According to this law, all suppliers engaged in the supply of goods and services with an aggregate turnover above the threshold limit are compulsorily required to register under GST and follow the rules and procedures specified therein.

Threshold limit for GST registration

As per Notification 10/2019 of GST, it is mandatory for businesses that engage in the supply of goods and whose aggregate turnover is above Rs. 40 lakhs (Rs. 20 lakhs for special category states) in a financial year to register with GST.

Meaning of aggregate turnover

As per Section 2(6) of the CGST Act, aggregate turnover means the aggregate value of all taxable supplies (excluding inward supplies on which tax is payable on a reverse charge mechanism), exports, and supplies exempt from GST. Previously, the limit was Rs. 20 lakhs. But this was increased to Rs. 40 lakhs via notification no. 10/2019-Central Tax dated March 7th, 2019. It means aggregate turnover includes taxable supplies, exempted supplies, non-GST supplies, interstate supplies, zero-rated supplies, and goods sent for job work. It excludes goods received on which tax is payable under the reverse charge mechanism, goods on which GST is paid, and goods received for job work.

Voluntary GST registration

Any person or business entity that wishes to supply goods or services, or both, can voluntarily register under GST. Many companies have done so to enjoy the benefits of GST registration.

Types of GST Registration

  • Normal Taxpayer: Persons who conduct the business of supplying goods or services or both in India or persons who engage in economic activity, including trade and commerce, are considered taxable persons and are required to register with GST.
  • Composition Taxpayers: To lower the burden of compliance on small businesses, the government introduced the composition scheme, in which the tax rates are lower and compliance simpler. It is a voluntary scheme, in which businesses with an aggregate turnover below Rs. 1.5 crores (Rs. 75 lakhs for Uttarakhand and north-eastern states) can opt for this scheme.
  • Casual Taxpayers: Persons or entities that establish businesses that are seasonal in nature should register under casual taxpayer registration in GST. They have to pay a deposit equal to the tax liability. The registration is active for a period of three months or the period applied, whichever is less.
  • Non-resident Taxable: Persons who supply goods to residents in India can do so only after registering in GST under non-resident taxable persons registration. They have to pay an advance deposit equal to the estimated tax liability. The registration is valid for three months or until the completion of the supply.

Documents required for GST registration

  • Proof of the constitution of a business, like a certificate of incorporation
  • Passport-size photo of the authorized signatory, like the promoter, partner, proprietor, etc.
  • Proof of the principal place of business, like an electricity bill, a municipal khata certificate, a property tax receipt, etc.

GST registration process

GST registration can be done through the GST portal online. It can be done free of cost. After registration, a GST registration certificate and a 15-digit GST identification number (GSTIN) are obtained by the taxpayer. GST registration helps in the collection, payment of taxes, and filing of returns on the portal as part of the compliance process. It is also needed to avail input tax credit on the inward supplies.

Tips to ensure a compliant GST registration status

This helps in the control of cash flow and also helps them make better business decisions.
  • Regular Reconciliation: It is important for businesses to reconcile their financial statements with the GST returns so that the discrepancies can be identified and rectified. This ensures accuracy in tax computation and filing returns.
  • Updated with GST rules and regulations: GST authorities regularly pass notifications and advisories with regard to the changes in the rules and procedures. The taxpayers should be properly informed about the changes so as to avoid penalties for non-compliance.
  • Internal Audits: Businesses should arrange for regular internal audits for early detection of discrepancies and prompt remedial actions to stay compliant. This saves time and maximizes the benefits of registration for businesses.
  • Identify and claim the correct ITC. Businesses should be aware of the costs that are eligible for claiming ITC because not all costs are covered. Errors in claiming ITC can cause problems later, so taxpayers need to be aware of the criteria for claiming ITC correctly.
