GST Return Filing in India: A Comprehensive Guide

Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax levied on the supply of goods and services in India. Every registered GST taxpayer is required to file periodic returns with the GST Department, detailing their sales, purchases, output GST, and input tax credit (ITC).

Filing GST returns correctly and on time ensures legal compliance, avoids penalties, and maintains seamless flow of input tax credit.
