GST 2.0: what changed in 2025 and what it means for startups

GST 2.0 is the popular name for the simplified Goods and Services Tax structure announced after the 56th GST Council meeting in early September 2025. Before it, most items sat in four main slabs: 5%, 12%, 18% and 28%. The reform removed the 12% and 28% slabs for most items, leaving 5% and 18% as the two main rates, as reported by outlets and tax-adviser summaries.

A third rate of 40% applies only to a short list of goods the Council treated as sin or luxury items. Reports named examples such as sugary drinks, pan masala and high-end cars. Reports differ on timing for tobacco, whose rates were to be notified separately because of pending cess matters, so that part needs checking against official notifications.

The GST Council, the body of the Union and state finance ministers, approved the structure at its 56th meeting on 3 September 2025. The new rates were reported to apply from 22 September 2025, once the Central Board of Indirect Taxes and Customs issued notifications.

Because the Council works by consensus and the states share GST revenue, rate changes need agreement. Founders should watch the Council's meetings, since a rate can change with a single notification even without new legislation.

For a startup, the practical point is to subscribe to CBIC notifications or ask the accountant to flag them, because a rate or exemption can change between filings.

The list below sums up the structure as reported. Item-level rates differ, so a startup must check the exact tax code for its product.

• 5%: essentials and many everyday items that moved down from 12%, such as a wide range of packaged foods and household goods.
• 18%: the standard rate for most other goods and services, including items that moved down from 28%, such as many consumer appliances and small cars, per press reports.
• 40%: a narrow list of sin and luxury goods.
• 0% and exempt: some essentials remain nil-rated or exempt, per summaries.
• Services such as software and IT services were generally already at 18% before the change.

Direct-to-consumer brands that sell packaged food, personal care or household items may have moved to a lower slab. A lower rate can cut the price a customer pays, or let the brand keep a larger share of the price. Which one happens depends on competition and pricing power.

A change in rate also affects stock already in the warehouse. A brand that bought inputs at a higher rate and sells finished goods at a lower rate can be left with unused tax credit that it cannot easily convert to cash. Advisers call this an inverted duty situation, and it is worth asking an accountant how the rules treat it for a given product.

Food and beverage brands should check each product's new code and rate. A move from 12% to 5% helps price points, but a move into the 40% slab for a sugary drink hurts. Electric vehicles had a 5% rate before the reform, and press summaries described that rate as unchanged, while many conventional vehicles moved down, which can narrow the price gap for buyers.

Consumer electronics makers should note that televisions and large appliances were reported to move from 28% to 18%. That can raise demand but also raise price competition between brands, so unit margins may not grow as much as the tax cut suggests.

Software and IT services were mostly at 18% already, so the slab overhaul did not change the headline rate for most SaaS companies. Export of services can still be zero-rated, which means no GST is charged on the export while input tax credit can be claimed. The separate guide on GST for SaaS exports covers the conditions.

The change matters more for what a SaaS startup buys: office equipment, devices and certain services whose rate may have moved. Cheaper inputs can slightly lower costs, but the effect is usually small.

Rate changes create paperwork. The steps below are a reasonable starting list, not tax advice.

• Check the tax code and rate for each product against the latest CBIC notification.
• Update the billing system, price lists and invoice templates.
• Review unused input tax credit and ask whether any can be refunded or must be carried forward.
• Decide whether to pass the saving to customers or keep it as margin, and tell the sales team.
• Update the financial model so that revenue, gross margin and cash tax reflect the new rate.

The old system was built in 2017 with five rates in practice: 0%, 5%, 12%, 18% and 28%, plus a special rate on gold and a compensation cess on some goods. Businesses often argued over which slab an item belonged in, and such arguments ended in tax tribunals and courts. Two main slabs make classification disputes fewer, since there are fewer boundaries to fight over.

The 40% rate has its own logic. It is meant for goods the government wants to tax heavily for health or luxury reasons. Startups that make anything close to sugary drinks, tobacco-linked products or high-end vehicles should check that rate first.

Investors read tax changes through margins and demand. A consumer startup whose products moved to a lower slab may show a better growth rate in the quarters after the change, because prices fall or volumes rise. Analysts then ask whether the growth is lasting or a one-time effect of the cut.

A startup preparing a pitch should separate the effect of the rate change from the underlying trend in its numbers. Showing revenue net of GST, units sold and average selling price side by side makes that separation easy to see.

A headline saying GST was "cut" on an item should be checked for the date and the exact code. Some changes come with a delay, and some cuts are on inputs, not on the finished product. Prices on shelves do not always fall by the full tax cut.
