GST Rate Structure Simplified: 5%, 18%, and 40% Slabs Explained

Auto-drafted from official sources and under review by CA Rajeev Ranjan. Verify against the original notification before you act.

What Has Changed

India's GST rate structure has been significantly simplified following the 56th GST Council meeting in 2025. The earlier four-slab system has been replaced with a cleaner three-rate framework:

• 5%, for essential or lower-ticket goods and services
• 18%, the primary standard rate covering most goods and services
• 40%, a special rate applicable to select goods and services (refer to the official notification for the exact list)

The 12% and 28% slabs have been removed. Goods and services previously taxed at 12% or 28% will now fall into one of the three remaining categories. Which items move where is critical, check the official notification for the reclassified list.

Why This Matters

This is one of the most significant structural changes to GST since its introduction. Fewer slabs mean:

• Simpler classification decisions for businesses
• Less disputes over which rate applies
• Potentially lower or higher tax burden depending on where your goods/services land

The 40% rate signals that the Council is retaining strong deterrent taxation for certain categories without the older 28% cess structure, though the exact goods covered should be verified from the official notification.

Who Is Affected

Almost every GST-registered business will need to review this change, but particularly:

• Manufacturers and traders whose goods were taxed at 12% or 28%
• Service providers in the 12% bracket (many professional and hospitality services)
• E-commerce operators who apply TCS and need correct rate mapping
• Accounting and ERP teams maintaining HSN/SAC rate masters

What You Should Do Now

1. Identify your current rate exposure, list every HSN/SAC code your business uses and the rates currently applied.
2. Cross-check against the official reclassification, the PIB press note and subsequent CBIC notification will carry the revised rate schedules. Do not assume which slab your product moves to.
3. Update your billing software, ERP, and rate masters before the effective date stated in the notification.
4. Review open purchase orders and contracts, if your pricing was built on the old rate, renegotiation or amendment may be needed.
5. Train your accounts and compliance team, incorrect invoicing under the new structure will create GST mismatches and potential demand notices.

Timing

The change is effective from the 56th GST Council meeting (2025). A specific implementation date will be published in the corresponding CBIC circular or gazette notification, watch for that and plan your cutover accordingly.

When in doubt on any specific product or service classification, refer to the official notification rather than assuming continuity from the old slabs.
