New GST Slabs Explained - 5% & 18% (Effective Sept 22, 2025)

India’s GST Council has approved a simpler rate structure - two primary slabs of 5% and 18%, plus a special 40% band for select demerit/luxury items. For households, invoices get simpler and several items are expected to become cheaper; for businesses, it’s time to remap rates, SKUs, and software before the rollout.

What exactly changed?

Put simply, India is moving from the old (5% / 12% / 18% / 28%) grid to a cleaner structure with two core rates - 5% and 18% - and a 40% band reserved for a narrow set of demerit goods and services. The policy intent is straightforward: simplify rate disputes, ease compliance, and support consumption.

Old vs New at a glance

Effective date & rollout

• Go-live: 22 September 2025 for services and most goods.
• Exceptions: Certain demerit categories (e.g., tobacco classes) may continue under existing structures temporarily and migrate via specific notifications.

What to do now (businesses): update POS/ERP tax masters, remap HSN-to-rate, refresh e-invoice logic, revise MRPs and quotations/AMCs, and train staff on the new totals at checkout. Watch for CBIC notifications that codify item-wise mappings and any staggered dates.

Real-world savings

Illustrative only - final math depends on item classification and the official notification.

1. Insurance premium (family floater): If an annual premium of ₹25,000 earlier attracted 18% GST (₹4,500), a move to a lower rate or exemption would reduce or eliminate this tax component, lowering out-of-pocket cost.
2. Consumer durable (e.g., AC/Refrigerator): On an MRP of ₹40,000, a shift from a higher band to 5% could materially reduce the invoice total once new MRPs are published.
3. Entry-segment car (≤350cc class): A rate move from 28% to 18% (model-specific cess rules apply) can lower the tax outlay; the net change depends on ex-showroom price, dealer charges, and any cess.

Macro view

• Simpler slabs reduce classification disputes and admin time.
• Consumption boost is likely in FMCG, durables, and entry-level autos.
• Potential inflation nudge down as rate cuts pass through.
• Revenue neutrality relies on buoyancy and compliance gains.
• Improved insurance and healthcare affordability as rationalised rates filter through.

FAQs

What are the new slabs?

Two core rates - 5% and 18% - plus a 40% demerit band. Essentials remain Nil.

From when do the new rates apply?

The rollout begins 22 September 2025 for services and most goods; some demerit items may transition later via notification.

Are all 28% items gone?

Many categories shift to 18%, while demerit items are addressed via the 40% band or transitional notifications.

Will my insurance premium drop immediately?

Where rates are reduced or exemptions apply, savings should reflect from the effective date or policy renewal. Check your insurer’s communication and the final notification.

How will transitional ITC work if the output rate falls?

Follow CBIC guidance on ITC and pricing; businesses should update ERP, re-price SKUs, and pass legitimate reductions to customers.
