GSTR-3B Filing Practical Guide: ITC Set Off, Interest Calculation & Challan

Understanding GSTR-3B Filing Updates

• 💡 The video provides a practical guide to GSTR-3B filing, focusing on the latest updates for ITC set-off rules and interest calculation.
• 🎯 A key advisory states that the cash ledger balance is considered, which generally helps reduce interest liability.
• 📌 The content is designed for accountants, students, and job seekers needing real-world GST filing knowledge.

Interest Calculation Logic

• 📊 Interest is calculated at 18% only on the cash payment portion of tax liability, not on the amount offset by ITC.
• ⏳ The interest is calculated from the due date until the payment date, based on the number of days delayed.
• 💡 A simple interest formula is used: (Amount * Rate * Days) / 365, with separate calculations for IGST, CGST, and SGST.
• ✅ If a cash ledger balance exists from previous payments or TDS/TCS claims before the due date, the interest is calculated only on the remaining cash liability.

Practical Steps on GST Portal

• 💻 The video demonstrates how to open GSTR-3B on the GST Portal and navigate through its sections.
• ⚠️ It highlights that late fees for the current month carry forward to the next month's calculation.
• 🧠 Users can self-calculate interest or wait for the portal's auto-calculation, which might not appear immediately.

Invoice Management System (IMS) & GSTR-2B

• 🛠️ To open GSTR-3B, users must first file GSTR-1 and then use the Invoice Management System (IMS) to accept relevant invoices.
• 🔍 The process involves navigating to the IMS dashboard, viewing inward supplies, and accepting B2B invoices for the current and previous months.
• ✅ After accepting invoices, users need to compute GSTR-2B to generate the final document, which then allows GSTR-3B to be opened.

Generating Challans & Final Filing

• 💰 The portal automatically calculates ITC set-off, and any remaining tax, interest, or late fees require a cash payment.
• 🚀 To make cash payments, a challan (PMT-06) is generated through the "Make Payment Post Credit Ledger" option.
• 📝 Once the challan is paid and the cash ledger is updated, the final GSTR-3B return can be filed by verifying with an OTP.
