Features of GST in India: Top 10 Salient Features Explained (2026)

Goods and Services Tax, or GST, replaced several indirect taxes prevailing in India, including excise duty, VAT, and service tax, in 2017. The latest reform in the GST regime, known as GST 2.0, further simplified the GST tax slab structure that will apply from September 2025. In whatever form your business entity exists, be it a shopkeeper, online trader, or service provider, you should be aware of these top 10 GST features.

• GST replaced 17 direct and indirect central and state taxes (including VAT, excise duty, service tax, and CST) on 1st July 2017.
• The latest GST 2.0 reform in India on 22nd September 2025 reduced the former 4-tier tax slab structure (5%, 12%, 18%, 28%) to primarily two slabs, i.e., 5% and 18%, with an additional 40% slab rate for luxuries.
• A dual taxation system is followed, with CGST plus SGST applied to intrastate sales and IGST applied to interstate sales.
• The input tax credit allows you to deduct the tax paid earlier for any business purchase at each stage of the supply chain from the tax payable at that stage.
• Registration becomes mandatory once your business turnover reaches a threshold limit of ₹40 lakhs (goods) or ₹20 lakhs (services).

Goods and Services Tax, or GST, is a unified indirect tax system that applies to the supply of goods and services anywhere in India. It replaces a variety of indirect taxes with a single tax levied at each step of the supply chain, with a provision for credit of previously paid taxes. In short, it makes for one tax system for the entire country and one tax return for each business.

1. Single Unified Taxation System

GST has replaced 17 direct and indirect central as well as state taxes, including excise duty, VAT, service tax, CST, octroi, and many others. Earlier, a commodity used to be subjected to multiple levies before reaching the final consumer due to the cascading effect of the tax-on-tax nature of indirect taxes. However, GST ended this issue by applying only one tax on the added value.

Consequence: Now, you have to follow just one tax law and register with only one tax authority, irrespective of state lines.

2. Destination-Based Consumption Tax

GST is levied at the location of consumption rather than at the place of manufacturing. Suppose the goods are manufactured in Gujarat but sold in Kerala; then, it is Kerala and not Gujarat that receives the GST revenue.

Consequence: Therefore, you have to consider the point of consumption while invoicing each transaction.

3. Dual GST Taxation System (CGST and SGST/IGST)

When you sell the product to someone else in the same state, you must charge both CGST and SGST; for interstate sales, you must charge only IGST.

CGST + SGST = Intrastate Sale

IGST = Interstate Sale

A similar taxation system, called UTGST, applies to union territories without a legislative assembly.

Caution: One of the most common mistakes made by small taxpayers while filing returns is charging IGST in place of CGST and SGST or vice versa while making incorrect sale type entries.

4. Multistage Taxation Process with Input Tax Credit Facility

GST applies at all stages of the supply chain process, starting from the procurement of raw materials from suppliers through manufacturing, sales to wholesalers, sales to retail dealers, and delivery to the ultimate consumer. But at every stage of the supply chain, the supplier is allowed to claim an input tax credit of previously paid taxes to pay only the difference.

Caution: it means that you should save all your purchase invoices that show the GSTIN of the seller.

5. Four-Tier Slab Rates Structure (now reduced under GST 2.0)

For eight years from the launch of GST on 1st July 2017, the tax rates were classified as Nil (0%), 5%, 12%, 18%, and 28%, with an additional cess being leviable on selected 'luxuries' and 'sin' items, such as aerated drinks and tobacco products. The most recent reform, however, removed the 12% and 28% slabs and kept only 5%, 18%, and 40%.

Note: The new GST slab does not apply to cigarettes, chewing tobacco, and beedi, at least for now, until the government clears all the pending interest on the loan exchanged for the compensation cess; therefore, check the actual GST rates of your products through the GST rate finder portal first.

6. GST Registration Requirement
Under GST laws, you should be mandatorily registered once your annual business turnover exceeds the limits below:

*Special category states: Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand.

Also, regardless of turnover amount, you are required to compulsorily register yourself in these cases:

• Supply of goods & services via an electronic commerce platform.
• Selling beyond state borders.
• You are liable to pay tax under the Reverse Charge Mechanism.

7. Composition Scheme

Once your turnover falls below the threshold limit, you may choose the composition scheme in place of normal GST. Under this scheme, you pay a lower percentage of the GST instead of the turnover amount and maintain only quarterly and annual return records instead of several monthly returns.

Good to Know: Since the composition scheme, taxpayers cannot claim Input Tax Credit; it would be beneficial for those who cater to individual consumers only.

8. GST Council – Composition and Functions

GST Council has full powers regarding setting various GST laws related to rates, exemptions, threshold limits, etc. The council was established under Article 279A of the Constitution and is presided over by the Union Finance Minister, with each state's finance/revenue minister as a member.

One-third weightage is assigned to the vote cast by the centre, while two-thirds weight is given to all the state votes combined.

Consequence: As a result, GST laws could be amended anytime following the council meetings.

9. Goods and Services Tax Network (GSTN)

It is the IT backbone of the entire GST system. GSTN takes care of the registration of taxpayers, tax payments, return filings, and input tax credit matching.

Consequence: you could manage everything, including GST returns, registration, and refund status, online.

10. Reverse Charge Mechanism (RCM)

Under the normal GST mechanism, it is the supplier of goods/services who collects GST and remits it to the government. But in the reverse charge mode, it is the buyer who becomes responsible for paying the tax directly to the government rather than the supplier. This is the case when you buy something from an unregistered person or receive services like transport, etc.

Caution: Do remember to charge this tax on behalf of the government if you purchase any product/service from an unregistered supplier whose name appears in the notification.

11. E-Invoicing and E-Way Billing – Bonus Features

There are two important technological components of the GST system: e-invoicing and e-way bills.

• E-Invoicing: compulsory for businesses with annual turnovers exceeding ₹5 crores. Every B2B transaction needs to be uploaded to the Invoice Registration Portal (IRP) hosted by the government.
• E-Way Bills: required for consignments involving transport of goods valued above ₹50,000, whether inside or outside the state.

Consequences: if your annual turnover approaches the ₹5 crore mark, then you must start discussing e-invoicing requirements with your accounting software provider at the earliest, or you won't be able to issue valid invoices anymore.

One tax system across the nation: GST makes things easier for businessmen and saves time, as there is no need for separate state registrations.

• No tax-on-tax: Under GST laws, you pay GST only on the value you create, leaving room for savings in taxes.
• Easy interstate sales: you can sell your products easily across the states with zero extra taxes.
• Everything at one portal: you can register, file returns, and even check refund status online.
• Low prices on essential items: GST 2.0 reduced rates on household items that could bring down your costs of doing business.
• Easy access to loans: a clean record of GST filings becomes helpful in applying for loans from banks.

Certain goods and services, like petroleum products and alcohol for human consumption, remain out of GST jurisdiction and are subject to the old state taxes, resulting in dual GST compliance burdens on business.

• Heavy compliance burden on small taxpayers: even with simplified laws, complying with GST norms takes some time.
• Many rates continue: even in the face of GST 2.0, there remain four primary GST rates: Nil (0%), 5%, 18%, and 40%.
• Reliance on technology: since everything depends on the IT system, GST compliance becomes impossible if the portal slows down or crashes during critical moments.

The latest rate changes came into effect on 22nd September 2025 after the GST Council made its biggest-ever reform at its 56th meeting. Here are the key changes:

• Reduction in the number of tax slabs from 4 (Nil, 5%, 12%, 18%, and 28%) to three: Nil (0%), 5%, and 18%, with a separate rate of 40% on luxuries and 'sin' items.
• Tax relief to households: Soaps, shampoos, toothpaste, packed snacks (Namkeen), chocolate, coffee, pasta, and bicycles got reduced to 5%; UHT milk, paneer, and Indian breads got exempt from GST.
• Discounts to consumer durables and autos: TV, AC, dishwasher, cement, small car, two-wheelers up to 350cc, buses, trucks, and auto parts became cheaper at the rate of 18%.
• Health sector relief: 33 life-saving medicines, surgical kits, etc., are completely exempt from GST; the rest are reduced to 5%; individual health and life insurance premiums are exempt.
• Agriculture and Education sector relief: tractors, irrigation equipment, and farm implements received a reduction to 5%, and exercise books, crayons, and pencils became exempt.
• Services: hotels below ₹7,500 per night, gyms, salons, and yoga classes became eligible for exemption from GST.

Important exception: cigarettes, chewing tobacco (Zarda), unmanufactured tobacco, and beedi continue to pay the GST and cess charges at the same rate as earlier until the compensation cess loan is completely recovered. The new rates will be applicable from a yet-to-be-notified date.

Action step: you need to go through your products list again to confirm that your HSN to GST rate mapping in your billing software complies with the latest rate slab.

Penalty for failure: Using an old rate for billing any transaction violates Section 31 of the CGST Act and will land you in big trouble.
