New Delhi, Oct 19 (NationPress) The government has officially announced an extension of five days for the filing of the GSTR-3B tax return form. Taxpayers are now permitted to submit their returns and complete tax payments for both the month of September and the July-September quarter by October 25.
This update was communicated by the Central Board of Indirect Taxes and Customs (CBIC) in a notification released on Sunday.
The CBIC also shared the news via the social media platform X, stating, "@cbic_india extends the GSTR-3B filing deadline."
The GSTR-3B form serves as a summary return that businesses registered under GST must file either on a monthly or quarterly basis.
Typically, the due dates for these filings are the 20th, 22nd, and 24th of each month, depending on the taxpayer's category.
The extension of the deadline was anticipated, as the original due date of October 20 coincides with the Diwali festival, a period when many businesses and offices operate with reduced staff or are closed.
Experts believe this decision will offer relief to numerous businesses and tax professionals who would have struggled to meet the deadline during the festive season.
Earlier this year, GSTN clarified that while the GSTR-3B will still auto-populate based on sales data from forms like GSTR-1, any modifications or corrections must be done prior to filing, using GSTR-1A.
Once revised data is incorporated, it will appear automatically in GSTR-3B. After this, taxpayers will not have the option to manually edit GSTR-3B as they can do currently.
According to an advisory issued on June 7, "For the tax period of July 2025, due for filing in August 2025, the auto-populated tax liability in GSTR-3B will be final and cannot be altered post-filing."
This initiative is designed to enhance data accuracy across various GST forms and minimize tax leakage.
