What is GSTR-3B and when is it due?

GSTR-3B is a monthly self-declared summary GST return. For regular taxpayers, it is due by the 20th of the following month. Late filing attracts ₹50/day late fee (₹25 CGST + ₹25 SGST), capped at ₹5,000.

How do I reply to a DRC-01 GST notice?

DRC-01 is a show-cause notice for tax demand. Log in to GST portal, go to Services > User Services > View Additional Notices, select the notice and file a reply within 30 days — either agreeing and paying, or disputing with supporting documents.

What is the late fee for filing GSTR-1 late?

Late fee for GSTR-1 is ₹50/day (₹25 CGST + ₹25 SGST). For nil returns it is ₹20/day. Maximum cap is ₹10,000 per return. GSTR-1 is due by the 11th of each month for monthly filers.

Can I claim ITC on hotel and restaurant bills?

ITC on restaurant food and beverages is blocked under Section 17(5) CGST Act — not claimable. However, ITC on hotel accommodation is allowed if used for business purposes and the hotel provides a GST invoice with your GSTIN.

What is the GST registration threshold in India?

GST registration is mandatory if annual aggregate turnover exceeds ₹40 lakhs for goods (₹20 lakhs for special category states) or ₹20 lakhs for services (₹10 lakhs for special category states). E-commerce sellers must register regardless of turnover.

GST 2.0: 10 Game-Changing Rules from April 2026 Every Indian Business Must Know

India's GST system just got a major upgrade — and this time, there's no room for error.

Effective April 1, 2026, the government has rolled out what is being called GST 2.0 — a sweeping transformation of the tax framework backed by AI-powered scrutiny, real-time invoice matching, and zero tolerance for mismatches. Whether you're a small business owner, a CA, or running a large enterprise, these changes affect you directly.

Here are the 10 most critical changes you need to understand right now.

1. Goodbye to the 12% Slab — New 4-Tier Rate Structure

The old five-tier system (0%, 5%, 12%, 18%, 28%) is gone. GST 2.0 introduces a cleaner four-slab structure: 0%, 5%, 18%, and 40%. Items that were taxed at 12% have been moved to either 5% or 18%, and the 28% slab with cess is now a unified 40%. Businesses must immediately update their billing software and price lists to reflect these new rates.

2. The ITC Hard Block — Your Biggest Compliance Risk

This is perhaps the most disruptive change. From April 1, 2026, if the Input Tax Credit (ITC) you claim in GSTR-3B exceeds what is auto-populated in your GSTR-2B, the portal simply won't let you file. The submit button gets disabled. You become instantly non-compliant. There is no workaround — you must reconcile with your suppliers first.

3. Real-Time Invoice Management System (IMS) is Mandatory

Every registered taxpayer must now use the Invoice Management System (IMS) on the GST portal to Accept, Reject, or mark as Pending every invoice uploaded by their suppliers. Ignoring this is no longer an option — unaccepted invoices are automatically treated as rejected, which blocks ITC claims.

4. E-Invoicing is Now Universal

E-invoicing is now mandatory for all businesses with a turnover of ₹5 crore or more. If you are required to generate an e-invoice but skip it, that invoice is legally invalid. No ITC can be claimed on it by your buyer, and you face penalties of ₹10,000 per invoice.

5. Auto-Suspension for Missing Bank Details

If your GST registration does not have a verified bank account linked, your GSTIN will be auto-suspended — which means no e-way bills, no e-invoicing, and no filing. Check your portal today and link your account if you haven't done so.

6. AI-Powered Fraud Detection — Mismatches Flagged Instantly

The GST portal's Business Intelligence and Fraud Analytics (BIFA) system now flags variances above 5% between GSTR-1 and GSTR-3B almost in real time. India uncovered over 24,000 fake invoice cases in FY 2025-26 alone, with fraud amounts running into thousands of crores. If your numbers don't match, expect a notice — fast.

7. Nil Returns Are Now Compulsory

Every registered taxpayer must file a return for every tax period — even if there's zero business activity. Non-filing of nil returns for 6 consecutive months leads to automatic cancellation of your GST registration. This is a major risk for dormant entities.

8. Exporters Get a Major Refund Boost

Great news for exporters: the minimum ₹1,000 threshold for GST refund claims has been removed. Every valid rupee of refund will now be processed. Additionally, exporters with a clean 'Green Track' record will receive 90% of their refund within 7 days of filing.

9. Post-Sale Discounts — No Agreement Needed Anymore

Previously, businesses needed a pre-existing agreement in writing to give post-sale discounts under GST. That requirement is now removed. Businesses can issue credit notes and pass on discounts more flexibly — a relief for FMCG and distribution businesses.

10. Stricter HSN Code Validation — Rejections at IRN Stage

The GST portal now validates HSN codes in real time during e-invoice generation. If your HSN code does not match your registered product category, the Invoice Reference Number (IRN) is instantly rejected. Businesses must audit their product HSN mappings to avoid billing disruptions.

The Bottom Line

GST 2.0 is not a minor update — it is a fundamental shift toward a fully automated, AI-monitored tax system. The businesses that prepare now — by reconciling ITC, updating HSN codes, linking bank accounts, and training their finance teams — will navigate this smoothly. Those who don't will face penalties, suspended GSTINs, and blocked refunds.
