Diwali Relief: GSTR-3B Deadline Extended to October 25
The Central Board of Indirect Taxes and Customs (CBIC) has extended the GSTR-3B filing deadline to October 25, 2025, providing significant relief to taxpayers during the Diwali festival period. This extension comes as a welcome move for businesses and tax professionals who were facing challenges meeting the original October 20 deadline.
Key Takeaways
- GSTR-3B filing deadline extended from October 20 to October 25, 2025
- Applies to both monthly and quarterly filers
- Addresses concerns raised by chartered accountants about Diwali holidays
- Helps avoid late fees and compliance issues
Why the Extension Was Needed
The Bombay Chartered Accountants Society (BCAS) had formally requested the extension, highlighting that the original October 20 deadline fell immediately after a Sunday and coincided with the main Diwali festival days from October 20-23, 2025. BCAS noted that this created an “extremely tight – almost non-existent” compliance window during the festive week.
In their letter to the Finance Ministry, BCAS stated: “the standard statutory due date for furnishing the return is 20th October 2025. The same falls immediately after Sunday, 19th October 2025. Furthermore, the period encompassing 20th October 2025 to 23rd October 2025 coincides directly with the primary days of the Diwali festival, which is observed as a significant public holiday cluster across the country.”
Challenges During Festive Period
Preparing GSTR-3B involves substantial groundwork including reconciliation, data entry, reviewing Input Tax Credit eligibility, and arranging funds for tax payments. These tasks become particularly challenging during festival periods when accounting professionals and company staff are on holiday.
What is GSTR-3B?
Form GSTR-3B is a summary return where taxpayers declare their total GST liabilities for a tax period and make the required payment. Every regular taxpayer must file this return monthly to maintain GST compliance.
Importance of Timely Filing
Filing GSTR-3B on time is crucial because:
- It enables Input Tax Credit (ITC) claims
- It’s required for proper GSTR-1 submission
- Late filing attracts daily penalties:
- ₹50 per day (₹25 CGST + ₹25 SGST) for returns with tax liability
- ₹20 per day (₹10 CGST + ₹10 SGST) for nil returns
The extension provides taxpayers adequate time to complete their GST compliance procedures after the festival celebrations conclude.
