FAQs

Q1: What is the penalty for late GST return filing?

Under the Goods and Services Tax (GST) regime in India, the penalty for late filing of returns such as GSTR-3B is ₹50 per day (₹25 under CGST and ₹25 under SGST). This penalty is capped at a maximum of ₹5,000 per return. For nil returns, the late fee is reduced to ₹20 per day, with a maximum cap of ₹500. It's important to note that the late fee is calculated from the day after the due date until the return is filed, regardless of whether any tax is payable. Therefore, timely filing is crucial to avoid unnecessary penalties.

Q2: Is interest charged on late GST payments?

Yes, interest is charged at 18% per annum on the outstanding GST tax liability from the due date until the actual payment is made. This interest is applicable even if the return is filed on time but the payment is delayed. The interest is calculated on the unpaid tax amount for the period it remains unpaid, emphasizing the importance of timely payment to avoid additional financial burdens.

Q3: Can I claim input tax credit if I file returns late?

No, claiming Input Tax Credit (ITC) is contingent upon timely filing of returns. According to Section 16(4) of the Central Goods and Services Tax (CGST) Act, ITC can only be claimed if the return for the month of September following the end of the financial year is filed, or the annual return is filed, whichever is earlier. Therefore, delayed filing of returns can result in the loss of eligibility to claim ITC, affecting the overall tax liability and cash flow of the business.

Q4: How can businesses avoid late filing penalties?

To avoid penalties associated with late GST return filing, businesses should adopt proactive measures. Maintaining accurate and up-to-date records of all transactions ensures that returns can be filed promptly. Utilizing GST-compliant accounting software can automate calculations and reminders, reducing the risk of human error. Setting internal deadlines ahead of the official due dates can provide a buffer period to address any unforeseen issues. Additionally, consulting with tax professionals can provide guidance and ensure compliance with all GST regulations, thereby minimizing the risk of penalties.

Q5: Is GST registration required before filing returns?

Yes, obtaining GST Registration Online is a prerequisite for filing GST returns. Businesses must complete the GST registration process online to obtain a Goods and Services Tax Identification Number (GSTIN). This registration is mandatory for filing returns, making tax payments, and claiming Input Tax Credit (ITC). Without a valid GSTIN, a business cannot legally engage in activities under the GST regime, including the filing of returns.
