Types of GST in India Explained: CGST, SGST, IGST & UTGST with Examples (2026 Guide)

 

Types of GST in India – CGST, SGST, IGST & UTGST Explained 

It was a busy Monday morning at Riya's Café. The breakfast rush had finally slowed down, and Riya sat at the counter with a pile of invoices from different suppliers. She had carefully organized them after learning about GST in the previous chapter. As she compared the bills, something caught her attention.

One invoice showed:

• CGST – ₹90

• SGST – ₹90

Another invoice displayed:

• IGST – ₹180

A third bill from a supplier in Chandigarh mentioned:

• CGST

• UTGST

Riya : Sharma Ji, yesterday you told me that GST is one tax. Then why do these invoices have different names? Why isn't everything simply called GST?

Sharma Ji : I was waiting for this question.

He picked up a notebook and drew a map of India.

Sharma Ji : Today you'll understand one of the most important concepts in GST. Once you understand the different types of GST, reading any GST invoice will become much easier.

Why Does GST Have Different Types?

At first glance, it may seem confusing. If GST is a single tax, why do businesses use four different names? The answer lies in India's federal system of government. India has two major levels of government:

• Central Government

• State Governments

Both governments need tax revenue to run the country. For example: The Central Government spends money on:

• National highways

• Defence

• Railways

• Airports

• National-level welfare schemes

State Governments spend money on:

• Schools

• State roads

• Hospitals

• Police

• Local development

Before GST, both governments collected different indirect taxes separately. When GST was introduced, the government wanted to simplify taxation without taking away either government's share of revenue. Instead of one authority collecting everything, GST was designed so that the tax is divided appropriately between the Centre and the States depending on where the transaction takes place. That's why GST has different components.

The Four Types of GST

Sharma Ji wrote four names on the notebook.

1. CGST

2. SGST

3. IGST

4. UTGST

Riya : So GST isn't four different taxes?

Sharma Ji : No, They are four parts of the same GST system. Each one is used in a different situation. Once you know where the buyer and seller are located, you'll immediately know which type of GST applies.

Understanding GST Through Riya's Café

Sharma Ji drew two simple situations.

Situation 1

Supplier → Bihar

Buyer (Riya's Café) → Bihar

Both are in the same state.

Situation 2

Supplier → Maharashtra

Buyer (Riya's Café) → Bihar

Now they are in different states.

Sharma Ji : This simple difference decides which GST type applies. 

Riya : So location matters.

Sharma Ji : Exactly.

Two Types of GST Transactions

Every GST transaction falls into one of two broad categories.

1. Intra-State Supply

"Intra" means within. When the seller and buyer are located in the same state or union territory, it is called an intra-state supply.

Example:

Seller → Patna, Bihar

Buyer → Gaya, Bihar

Since both businesses are in Bihar, this is an intra-state transaction. In such cases, the GST charged is divided between the Central Government and the State Government. This is where CGST and SGST come into the picture.

2. Inter-State Supply

"Inter" means between. If goods or services move from one state to another, it is an inter-state supply.

Example:

Seller → Mumbai, Maharashtra

Buyer → Gaya, Bihar

Since two different states are involved, the transaction is interstate. In this case, IGST is charged instead of CGST and SGST separately.

An Easy Trick to Remember

Sharma Ji wrote a simple memory trick.

Same State = CGST + SGST

Different States = IGST

Riya : That's much easier than memorizing long rules. 

Sharma Ji : Exactly, Most GST questions become easy once you remember this one rule.

Think of GST Like Sharing a Pizza 🍕

Imagine a pizza worth ₹200. If both the buyer and seller are in the same state, the pizza is shared equally. One slice goes to the Central Government. One slice goes to the State Government. That's exactly how GST is shared. But if the pizza is traveling from one state to another, the whole pizza first goes to one place before being distributed according to GST rules. That's why IGST is collected as a single tax.

Riya : I'll never forget this pizza example.

What is CGST?

CGST = Central Goods and Services Tax

This portion of GST belongs to the Central Government of India. Whenever an intra-state transaction happens, one part of GST is collected as CGST. Think of CGST as the Centre's share of the tax.

Example

Riya buys coffee beans from a supplier in Patna.

Purchase Value = ₹10,000

GST Rate = 18%

Since both businesses are in Bihar:

CGST = 9%

SGST = 9%

Instead of charging one 18% GST amount under a single heading, the invoice splits it into two equal parts. This ensures that both governments receive their respective share.

Where Does the CGST Money Go?

Riya : So does the supplier keep this money?

Sharma Ji : No. The supplier only collects the tax from the customer. Later, it is deposited with the government according to GST rules. CGST is ultimately credited to the Central Government. The supplier is only acting as a collector. This is an important point because many beginners think businesses earn this tax. They don't. GST collected from customers belongs to the government.

What is SGST?

SGST = State Goods and Services Tax

This is the State Government's share of GST. Whenever an intra-state transaction happens, SGST is collected alongside CGST. Both taxes appear together on the invoice.

Example

Riya purchases bakery ingredients worth ₹5,000 from a supplier in Gaya.

GST Rate = 12%

The invoice will usually show:

• CGST = 6%

• SGST = 6%

Although both are collected together, they are credited to different governments. CGST goes to the Central Government. SGST goes to the Bihar Government.

Why Are CGST and SGST Always Equal?

Riya : Every invoice seems to split the GST equally.

Sharma Ji : For most intra-state supplies, the applicable GST rate is divided equally between CGST and SGST.

For example:

Total GST Rate	CGST	SGST
5%	2.5%	2.5%
12%	6%	6%
18%	9%	9%
28%	14%	14%

This equal distribution helps ensure that both the Centre and the State receive their share from transactions taking place within the state.

A Common Beginner Mistake

Many new GST learners think:

"CGST and SGST are two separate taxes charged one after another."

That's not correct. They are simply two components of the same GST for an intra-state transaction. The customer pays one total GST amount, but the invoice shows how it is divided.  Understanding this distinction makes reading GST invoices much easier.

Real-Life Example from the Café

To make sure Riya had understood, Sharma Ji gave her one final scenario. A local bakery in Patna supplies fresh bread worth ₹20,000 to Riya's café in Gaya. Since both businesses are located in Bihar, the transaction is an intra-state supply. The applicable GST rate is 18%, so the invoice is divided as:

• CGST: 9%

• SGST: 9%

There is no IGST on this invoice because the goods never crossed a state boundary. Riya looked back at the invoice she had been holding earlier. Now it finally made sense.

Riya : So whenever I buy from a supplier within Bihar, I should expect to see CGST and SGST on the bill.

Sharma Ji : Exactly, In the next lesson, we'll look at what changes when you buy from another state and why IGST is used instead.

Chapter Recap

In this part, Riya learned:

• Why GST is divided into different components.

• How India's federal system requires tax sharing between the Central and State Governments.

• The difference between intra-state and inter-state supplies.

• The four types of GST: CGST, SGST, IGST, and UTGST.

• What CGST is and why it belongs to the Central Government.

• What SGST is and why it belongs to the State Government.

• Why CGST and SGST are usually charged together and split equally in intra-state transactions.

• A simple rule to remember: Same State = CGST + SGST.

Types of GST in India – CGST, SGST, IGST & UTGST Explained 

Riya leaned back in her chair, feeling much more confident than before.

Riya : So if I buy coffee beans from Patna, I pay CGST and SGST because both my café and the supplier are in Bihar.

Sharma Ji : Perfect! You've understood the first rule. 

Riya : But what if I order something from another state? Last month I bought a premium coffee machine from a company in Bengaluru. The invoice only showed IGST. 

Sharma Ji : That's exactly what we're going to understand today.

He opened his notebook and drew a map of India again, this time marking Bihar and Karnataka.

Sharma Ji : When goods or services cross state boundaries, GST works a little differently.

What is IGST?

IGST = Integrated Goods and Services Tax

Unlike CGST and SGST, which are charged together, IGST is charged as a single tax on inter-state supplies.

In simple words, whenever the seller and buyer are located in different states or union territories, IGST usually applies. Instead of splitting the tax into two parts on the invoice, the supplier charges one combined GST amount as IGST.

Why Was IGST Introduced?

Riya : Why couldn't the government simply continue charging CGST and SGST even for interstate sales?

Sharma Ji : Imagine how confusing that would become. Suppose a supplier in Maharashtra sells goods to a business in Bihar. If SGST of Maharashtra were charged, Bihar would receive nothing, even though the goods were being used there. If Bihar's SGST were charged directly, the supplier in Maharashtra would face practical and legal complications. To avoid this confusion, the government created IGST, which acts as a bridge between the Central Government and the states involved. This system makes tax collection smoother while ensuring that the appropriate state eventually receives its share.

How Does IGST Work?

Instead of collecting two separate taxes, the supplier collects one integrated GST amount. Later, through the GST settlement mechanism, the government distributes the revenue to the appropriate governments. The business purchasing the goods can also claim eligible Input Tax Credit according to GST rules. 

Riya : So businesses don't have to worry about how the government divides the money?

Sharma Ji : Exactly, Your responsibility is to charge or pay the correct type of GST. The government takes care of the settlement.

Practical Example of IGST

Sharma Ji gave Riya a real-life situation. Riya wanted to buy an imported espresso machine. She found the best supplier in Bengaluru, Karnataka. Details:

Seller → Bengaluru, Karnataka

Buyer → Gaya, Bihar

Machine Price = ₹1,00,000

Applicable GST Rate = 18%

Since the supplier and buyer are in different states, this is an inter-state supply.

Instead of showing:

• CGST

• SGST

The invoice shows:

• IGST = 18%

The total GST remains the same, but it is charged under a single heading.

Same Tax Rate, Different Structure

Riya : So whether it's intra-state or inter-state, the total GST rate can still be 18%? 

Sharma Ji : Exactly, The difference is not the tax rate. The difference is how the tax is collected.

For example:

Purchase Within Bihar

GST Rate = 18%

Invoice:

• CGST = 9%

• SGST = 9%

Purchase from Karnataka

GST Rate = 18%

Invoice:

• IGST = 18%

The customer still pays the applicable GST rate, but the invoice format changes based on the location of the buyer and seller.

Easy Memory Trick

Same State → Split GST = (CGST + SGST)

Different States → Single GST = (IGST)

Riya : This is much easier than memorizing complicated legal provisions.

Online Shopping and IGST

Riya : I often order café supplies from online marketplaces. Which GST applies there?

Sharma Ji : It depends on where the seller is located. Let's look at a few situations.

Situation 1

Seller → Bihar

Buyer → Bihar

GST Charged: CGST + SGST

Situation 2

Seller → Delhi

Buyer → Bihar

GST Charged: IGST

Situation 3

Seller → Tamil Nadu

Buyer → Bihar

GST Charged: IGST

The website itself doesn't decide the GST type. The location of the supplier and the place of supply determine which GST applies.

What is UTGST?

Riya : This bill from Chandigarh mentions UTGST instead of SGST. "What does that mean?"

Sharma Ji : That's our fourth type of GST.

UTGST = Union Territory Goods and Services Tax

UTGST is charged in certain Union Territories instead of SGST. Since some Union Territories do not have their own state governments, the GST structure is slightly different. Whenever an intra-territory supply takes place in eligible Union Territories, GST is generally divided into:

• CGST

• UTGST

instead of:

• CGST

• SGST

Where Does UTGST Apply?

Sharma Ji explained that UTGST applies in Union Territories that are administered directly by the Central Government and do not have their own legislature under the GST framework.

Examples include:

• Andaman and Nicobar Islands

• Lakshadweep

• Dadra and Nagar Haveli and Daman and Diu

• Chandigarh

Riya : So Delhi isn't on this list.

Sharma Ji : Correct.

Why Doesn't Delhi Use UTGST?

Delhi is a Union Territory. Yet GST invoices there usually mention SGST instead of UTGST. The same is true for Puducherry and Jammu & Kashmir, which follow different constitutional arrangements for GST administration.

Sharma Ji : Many beginners assume every Union Territory uses UTGST, but that's incorrect. Only the Union Territories covered under the UTGST Act use UTGST for intra-territory supplies. Understanding this distinction helps avoid mistakes while preparing invoices or studying for exams.

Practical Example of UTGST

Suppose a bakery located in Chandigarh supplies fresh cakes to a café within Chandigarh. Both the seller and buyer are in the same eligible Union Territory.

Applicable GST Rate = 12%

The invoice would generally show:

• CGST = 6%

• UTGST = 6%

There would be no SGST because the transaction is taking place within an eligible Union Territory.

Comparing All Four Types of GST

Sharma Ji smiled and drew a simple comparison table.

GST Type	Full Form	Used When	Tax Goes To
CGST	Central Goods and Services Tax	Intra-state supply	Central Government
SGST	State Goods and Services Tax	Intra-state supply	State Government
IGST	Integrated Goods and Services Tax	Inter-state supply	Collected by the Centre and later settled as per GST rules
UTGST	Union Territory Goods and Services Tax	Intra-territory supply in eligible Union Territories	Union Territory administration under the GST framework

Sharma Ji : Keep this table in mind It answers most beginner-level GST questions.

Common Mistakes Beginners Make

Before ending the lesson, Sharma Ji shared a few mistakes he had seen many new business owners make.

Mistake 1: Thinking IGST Means Imported Goods

Many people assume IGST is only charged on imported products. In reality, IGST is generally charged whenever there is an inter-state supply, even if both businesses are located within India.

Mistake 2: Believing Every Union Territory Uses UTGST

As Riya learned today, only certain Union Territories use UTGST. Delhi is a common example where people often make this mistake.

Mistake 3: Assuming Higher Tax Is Charged Under IGST

Some beginners think paying IGST means paying extra tax. That's incorrect. The applicable GST rate generally remains the same. The difference lies in how the tax is categorized, not in charging an additional amount.

Riya Finally Connects the Dots

Riya gathered all three invoices lying on the table. The first invoice had CGST and SGST. The second had IGST. The third had CGST and UTGST. 

Riya : I can now identify why each invoice looks different just by checking where the supplier and buyer are located.

Sharma Ji : That's the real goal of learning GST—not memorizing abbreviations, but understanding the logic behind them. As they closed the register for the day, Riya looked at one more invoice and noticed another unfamiliar term. It mentioned 'Place of Supply.'

Riya : Sharma Ji… if GST depends on the location of the buyer and seller, then what exactly is the 'Place of Supply,' and why is it so important? 

Sharma Ji : That's an excellent question—but it's a lesson for another day.

Chapter Recap

In this part, Riya learned:

• What IGST (Integrated Goods and Services Tax) is.

• Why IGST is used for inter-state supplies.

• How IGST simplifies tax collection between different states.

• Why online purchases may attract IGST depending on the supplier's location.

• What UTGST (Union Territory Goods and Services Tax) is.

• Which Union Territories use UTGST.

• Why Delhi does not generally use UTGST for intra-territory GST transactions.

• A comparison of CGST, SGST, IGST, and UTGST.

• Common mistakes beginners make while identifying GST types.

The next morning, Riya reached her café carrying a small file. Inside were invoices from different suppliers she had worked with over the past few months. She placed them on the table in front of Sharma Ji.

Riya : Yesterday I finally understood the four types of GST but I still have one problem.

Sharma Ji : What is it?

Riya : I know what CGST, SGST, IGST, and UTGST are. But when I receive or create an invoice, how do I know which one to use? I don't want to make a mistake.

Sharma Ji : That's the most practical question you've asked so far. Today, we'll learn how to identify the correct GST type in real-life situations. Once you understand this, reading and preparing GST invoices will become much easier.

Step 1: Ask One Simple Question

Sharma Ji picked up a pen and wrote a single question in bold.

Are the buyer and seller located in the same state or in different states?

Sharma Ji : Before looking at tax rates or invoice amounts, always answer this question first.

Riya : So I don't start by checking whether it's CGST or IGST?

Sharma Ji : No. First, identify the locations. The GST type becomes much easier to determine after that.

A Simple Decision Rule

Sharma Ji drew a flowchart.

Buyer and Seller

        │
        ▼

Same State?
        │
   Yes ─────► CGST + SGST
        │
        No
        │
        ▼
       IGST

Sharma Ji : For eligible Union Territories, replace SGST with UTGST for intra-territory supplies.

Riya : This is much easier than memorizing long GST rules.

Scenario 1: Local Purchase

Riya buys fresh milk from a dairy in Gaya. Seller: Gaya, Bihar ; Buyer: Gaya, Bihar ; Both businesses are in the same state.

Applicable GST:

• CGST

• SGST

Sharma Ji : This is the easiest example of an intra-state supply. 

Scenario 2: Purchase from Another State

A supplier in Jaipur sends disposable coffee cups to Riya's café in Bihar.

Seller: Rajasthan ; Buyer: Bihar ; Different states.  Applicable GST: IGST

Riya : No CGST and SGST?

Sharma Ji : No, When the transaction is interstate, IGST is generally charged.

Scenario 3: Café Interior Design Service

Riya hires an interior designer from Patna. The designer and the café are both located in Bihar. Since both parties are in the same state, the invoice will usually include:

• CGST

• SGST

Sharma Ji : GST doesn't apply only to goods. It also applies to many taxable services.

Scenario 4: Software Subscription

Riya purchases café management software from a company based in Karnataka. Although the software is delivered online, the supplier is located in another state. The transaction is treated as an inter-state supply.

Applicable GST:

• IGST

Riya : So even digital services can attract IGST?

Sharma Ji : Yes, Goods and services both follow GST rules.

The Importance of "Place of Supply

Riya : What exactly is the 'Place of Supply'?

Sharma Ji : The Place of Supply is a GST concept used to determine whether a transaction is treated as intra-state or inter-state. It helps decide which type of GST should be charged. For many common business transactions, determining the place of supply is straightforward, but for some services, exports, imports, and special transactions, the rules can be more detailed.

Sharma Ji : As a beginner remember one thing: the place of supply is one of the key factors that decides whether CGST and SGST apply or whether IGST applies.

Why Charging the Wrong GST Is a Problem

Riya : What if someone accidentally charges CGST and SGST instead of IGST?

Sharma Ji : That mistake can create unnecessary compliance issues.

If the wrong GST type is charged:

• The invoice may need correction.

• Tax reporting may become inaccurate.

• The buyer could face difficulties while claiming eligible Input Tax Credit.

• Additional compliance work may be required.

That's why businesses verify customer details and GST registration information before issuing invoices.

Tips for Students and Beginners

Sharma Ji shared a few simple habits.

1. Don't Memorize Without Understanding

Instead of remembering four abbreviations, understand when each one is used.

2. Always Check the Locations

Whenever you see a GST question, identify:

• Seller's location

• Buyer's location

This simple habit solves many questions.

3. Read Real GST Invoices

The more invoices you read, the easier GST becomes.

Notice:

• GSTIN

• Supplier details

• Buyer details

• Tax breakup

• Invoice number

• GST amount

Real examples help build confidence.

4. Practice with Everyday Purchases

Look at restaurant bills, electronics invoices, or business purchase invoices.

Try identifying:

• Is it intra-state?

• Is it inter-state?

• Which GST type has been charged?

Learning becomes much easier when connected to everyday life.

Quick Comparison Table

Situation	GST Type Charged
Buyer and seller in the same state	CGST + SGST
Buyer and seller in different states	IGST
Buyer and seller in the same eligible Union Territory	CGST + UTGST
Goods or services supplied across state boundaries	IGST

Revision Tricks for Exams

Riya : What if I forget everything during an exam?

Sharma Ji : Then remember these four lines.

• CGST = Central Government's share

• SGST = State Government's share

• IGST = Different states

• UTGST = Eligible Union Territories

If you remember these, you can answer many beginner-level GST questions.

Why Understanding GST Types Matters

Before closing the lesson, Sharma Ji explained why this topic is important beyond exams.

If you become an accountant, you'll prepare invoices. If you become a business owner, you'll issue GST bills. If you work in finance or taxation, you'll review GST returns. If you become a Chartered Accountant, you'll advise clients. Understanding GST types is therefore a practical skill used in business, accounting, taxation, auditing, and financial compliance.

Riya : When I first saw CGST, SGST, and IGST on invoices, they looked like confusing codes.

Sharma Ji : and Now ? 

Riya : Now I know they're simply different parts of the same GST system, chosen according to where the transaction takes place.

Sharma Ji : Exactly. Once you understand the logic, GST becomes much less intimidating. 

As they prepared to close the café for the evening, Riya picked up another document from her accountant.

It was titled "Income Tax Computation."

Riya : We've spent so much time learning about GST, which customers pay when buying goods and services. But this document talks about income tax. Is that different from GST?

Sharma Ji : It is very different—and understanding that difference is essential for every student and business owner. That will be our next chapter.

Next Chapter Preview (What is Income Tax?)

As they locked the café, Riya asked one final question:

"Customers pay GST when they buy products from my café. But my accountant says I also have to understand Income Tax. Are GST and Income Tax the same?"

Sharma Ji : Not at all. GST is a tax on the supply of goods and services, while Income Tax is a tax on the income a person or business earns. Tomorrow, we'll explore 'What is Income Tax?' and understand who pays it, why it exists, and how it differs from GST—using your café's earnings as our next real-life example.
