What is GST Return Filing?

GST Return Filing is the process through which registered taxpayers report their sales, purchases, tax collected, and tax paid to the government under the Goods and Services Tax (GST) system.

Every GST-registered business must file GST returns within the prescribed due dates, even if there is no business activity during the period. Filing accurate returns is essential to avoid penalties, notices, and Input Tax Credit (ITC) mismatches.

GST returns are filed online through the official GST portal.
