GST rate list after the 2025 slab changes

What changed in the GST rate list in September 2025?

The GST Council’s September 2025 rationalisation moved the system towards two main slabs, 5% and 18%, alongside a 40% rate for specified sin and luxury supplies. The general effective date was 22 September 2025. That headline is a useful overview, not a complete product-level rate schedule. Exempt supplies, special rates, conditional entries, and separately implemented categories mean businesses should not replace every old rate in their accounting software using only those three numbers.

The Council recommends changes, while legally operative notifications and their effective dates determine the treatment of a supply. For an invoice issued today, check whether later amendments have changed the original September 2025 position. This article explains how to use a GST rate list safely rather than claiming to reproduce every tariff entry. Confirm item rates and current notifications at cbic-gst.gov.in before quoting a tax-inclusive price, revising a contract, or filing a return.

How should you read the 5%, 18%, and 40% slabs?

A stated GST rate normally means the combined tax burden, not an amount charged twice. For a usual intra-state supply attracting 18%, the invoice generally shows 9% central tax and 9% state tax. An inter-state supply generally attracts 18% integrated tax instead. The same distinction applies to other combined rates, subject to the relevant legal provisions. Determine the location and place of supply before choosing between a split local tax and integrated tax.

The 5% slab covers specified supplies identified in the schedules; it is not a blanket small-business rate. Similarly, 18% is a major slab but not a lawful default for every uncertain product. The 40% rate applies only where the notified entry says so. Some supplies may remain outside these headline bands or follow special implementation arrangements. Treat the classification, description, conditions, and effective date together as the rate rule rather than treating the percentage as a standalone answer.

How do you find the correct HSN or SAC code?

Goods are classified using HSN-based tariff descriptions, while services use the applicable service classification framework and SAC descriptions. Begin with what is actually supplied: composition, function, packaging, technical characteristics, and the contractual service obligation can all matter. A marketing name alone rarely settles classification. For example, a product described commercially as a wellness drink may require analysis of its ingredients and tariff treatment rather than an assumption that every health-related product receives a concessional rate.

Search the current CBIC schedules and relevant amendments, then read the full entry and any linked conditions. If two classifications appear possible, examine tariff notes, explanatory material, and relevant official clarification rather than choosing whichever rate is lower. Document your reasoning for material products. Where the issue is recurring and financially significant, professional advice or an advance ruling may be appropriate, remembering that an advance ruling has a defined statutory scope and is not universal protection for all taxpayers.

Does exempt mean the same thing as zero-rated?

No. An exempt supply and a zero-rated supply can both appear to involve no output tax in a particular transaction, but their input tax credit and refund consequences differ. Zero rating principally concerns qualifying exports and supplies to SEZ developers or units for authorised operations under the IGST framework. Exempt supplies ordinarily restrict related input tax credit, subject to the governing provisions. Nil-rated, exempt, non-taxable, and zero-rated should therefore not be used as interchangeable accounting labels.

This distinction affects pricing. A supplier selling exempt goods may bear GST on business inputs without being able to recover all of it through credit, while an eligible exporter may have a different credit or refund route. Suppose two businesses each bill a customer without output GST: their margins may still differ because one loses input credit and the other qualifies for zero-rated treatment. Establish the legal category before configuring invoice templates, return classifications, or refund expectations.

How do you calculate GST on a selling price?

For a tax-exclusive price, multiply the taxable value by the applicable rate. If a correctly classified supply is priced at ₹10,000 before GST and attracts 18%, tax is ₹1,800 and the total is ₹11,800. For an ordinary intra-state transaction, that tax would generally be split into ₹900 CGST and ₹900 SGST. This is only a calculation example; it does not establish that the particular goods or services in your business attract 18%.

For a GST-inclusive price, extract the tax rather than adding it again. At an assumed 5% rate, an inclusive selling price of ₹1,050 contains a taxable value of ₹1,000 and GST of ₹50. The formula is inclusive price multiplied by the rate, divided by 100 plus the rate. Discounts, subsidies, reimbursements, related-party pricing, and composite supplies may alter the taxable value, so confirm valuation before treating simple arithmetic as the complete legal analysis.

What happens when a rate changes during a transaction?

A rate change can affect transactions where supply, invoicing, and payment occur on different dates. Section 14 of the CGST Act contains specific rules for changes in rate, so the invoice date alone does not always decide the answer. Review when the supply occurred, when the invoice was issued, and when payment was received. Maintain evidence for all three events, particularly for advances, milestone contracts, subscriptions, and supplies spanning the effective date.

For existing stock, the purchase date does not automatically preserve the former output rate when the goods are sold later. Determine the rate applicable to the outward supply and separately examine credit eligibility on earlier purchases. Update point-of-sale systems, marketplace listings, product masters, and customer contracts together. A retailer that changes the shelf price but leaves an old tax code in the billing software can create mismatches between receipts, collected tax, and the return even without intending to overcharge.

How do rate changes affect input tax credit?

A lower output rate does not automatically cancel previously eligible input tax credit, but credit remains subject to the statutory conditions and restrictions. Exemptions, no-credit conditions, blocked credits, and mixed taxable-exempt use may require a different result. Match the supplier invoice, business use, receipt of supply, and prescribed reporting conditions. Do not assume that an invoice appearing in a portal statement conclusively proves entitlement, or that every business expense qualifies merely because GST was charged on it.

Rate changes can also create or alter an inverted duty situation, where input rates exceed output rates. Refund availability is governed by specific provisions, formulas, exclusions, and notifications, not by the simple existence of excess credit. Forecast the working-capital effect before reducing prices or increasing purchases. A manufacturer with substantial accumulated credit may need a refund assessment, while a service provider with restricted credits may need a pricing review rather than an assumption that the ledger balance is immediately recoverable cash.

Which supplies need extra care beyond the headline slabs?

Composite and mixed supplies need special attention because the tax treatment may depend on how items are naturally bundled and supplied. A separately sold product can have a different outcome when supplied as part of a qualifying composite contract. Restaurant, accommodation, real estate, transport, and financial arrangements can also involve specific conditions or valuation rules. Never apply a goods rate to a service merely because the service uses the same goods during delivery.

Specified tobacco-related and other specially treated categories should be checked for their own commencement and transitional arrangements rather than swept into the general reform date. Precious metals and other special-rate entries also show why the system cannot be reduced to three universal percentages. If compensation cess or another levy is relevant to the product and period, check it separately. A complete tax quotation should identify every applicable component rather than labelling the entire burden as a single generic GST slab.

How can a small business keep its GST rate list current?

Maintain a controlled product and service master recording the classification, description, rate, notification reference, effective date, and reviewer. Review high-value and high-volume items first, then investigate unusual supplier classifications instead of copying them automatically. Assign responsibility for monitoring official CBIC updates and testing billing changes. Keep the old version of each rate master so that a later audit can reconstruct why a historical invoice used a rate that differs from the current one.

When an error is found, assess the affected invoices, tax collected, returns, customer credits, and correction mechanism before changing data. A credit note, debit note, voluntary payment, or return adjustment may be appropriate depending on the facts and time limits. Do not silently edit issued invoices or assume a buyer can claim credit for any amount shown as GST. For current item-level confirmation, use CBIC’s official rate and notification resources and the GST portal’s operational guidance.
