The Goods and Services Tax (GST) system in India is a comprehensive, multi-stage, destination-based tax levied on the supply of goods and services. GST aims to streamline the indirect tax system, reduce tax cascading, and create a unified tax structure across the country. Here’s an overview of how the GST system works in India: 1. Structure of GST: 1.1. GST Framework: Central GST (CGST): Levied by the Central Government on intra-state supplies of goods and services. State GST (SGST): Levied by State Governments on intra-state supplies of goods and services. Integrated GST (IGST): Levied by the Central Government on inter-state supplies of goods and services and imports. It is designed to ensure that tax revenue is distributed between states and the central government. 1.2. Tax Rates: Standard Rates: GST has multiple tax slabs, including 5%, 12%, 18%, and 28%. Certain goods and services may also be exempt from GST or subject to a special rate. 2. GST Registration: 2.1. Requirement: Threshold Limit: Businesses whose aggregate turnover exceeds the prescribed threshold limit are required to obtain GST registration. The limit varies by state and type of business. 2.2. Process: Online Registration: Businesses must register online through the GST portal (https://www.gst.gov.in). The registration process involves submitting necessary documents and information. 3. Tax Collection and Payment: 3.1. Invoicing: Tax Invoice: Businesses must issue tax invoices for the supply of goods and services. Invoices must include details such as the GSTIN of the supplier and recipient, the value of supply, and the applicable GST rate. 3.2. Input Tax Credit (ITC): Claiming ITC: Businesses can claim input tax credit for the GST paid on inputs and services used in the course of their business. ITC can be offset against the output GST liability. Matching of Credits: Input tax credit claims are subject to verification and matching with the GST returns filed by suppliers. 3.3. Payment of GST: Monthly/Quarterly Payment: Businesses are required to pay GST on a monthly or quarterly basis, depending on their turnover. The payment is made online through the GST portal. 4. Filing GST Returns: 4.1. Types of Returns: GSTR-1: Details of outward supplies (sales) made by the business. GSTR-2: Details of inward supplies (purchases) received by the business. (Note: GSTR-2 has been suspended and information is auto-populated from GSTR-1.) GSTR-3B: Summary return of inward and outward supplies, along with the payment of tax. GSTR-4: Quarterly return for businesses under the composition scheme. GSTR-9: Annual return summarizing the yearly transactions. 4.2. Filing Process: Online Filing: Returns must be filed online through the GST portal within the prescribed due dates. Businesses must ensure accuracy in the data provided. 5. Audit and Compliance: 5.1. GST Audit: Mandatory Audit: Businesses with a turnover exceeding a certain threshold are subject to GST audit by tax authorities to ensure compliance. 5.2. Penalties and Enforcement: Non-Compliance: Failure to comply with GST regulations may result in penalties, interest, or legal action. 6. Goods and Services Tax Network (GSTN): 6.1. Role: IT Backbone: GSTN provides the technological infrastructure for the implementation of GST, including the GST portal for filing returns, making payments, and accessing GST-related information. 7. Special Schemes: 7.1. Composition Scheme: Simplified Scheme: Available for small businesses with a turnover below a specified limit. It allows businesses to pay GST at a reduced rate on their turnover instead of the regular tax rates. 7.2. Reverse Charge Mechanism: RCM: In certain cases, the recipient of goods or services is liable to pay GST under the reverse charge mechanism instead of the supplier. Summary The GST system in India aims to simplify the indirect tax structure by consolidating multiple taxes into a single tax. It operates on the principles of dual GST (CGST and SGST) for intra-state transactions and IGST for inter-state transactions and imports. The system involves registration, invoicing, tax collection, input tax credit, filing returns, and compliance with regulations. The GST framework is supported by the Goods and Services Tax Network (GSTN), which provides the technological platform for managing GST transactions and compliance.
