Types of GST in India Explained: CGST, SGST, IGST & UTGST with Examples (2026 Guide)
Types of GST in India – CGST, SGST, IGST & UTGST Explained (Complete Beginner's Guide)
Welcome to Finance with Aishira! 👋
Welcome back to Finance with Aishira, where Commerce, Accounting, Finance, Taxation, and Business concepts are explained in the simplest way possible.
What Are the Types of GST?
Although we commonly say GST (Goods and Services Tax), the tax is divided into four different components:
CGST (Central Goods and Services Tax)
SGST (State Goods and Services Tax)
IGST (Integrated Goods and Services Tax)
UTGST (Union Territory Goods and Services Tax)
These are not four separate tax systems. Instead, they are different parts of the same GST framework, designed to ensure that tax revenue is shared correctly between the Central Government, the State Governments, and certain Union Territories. The type of GST charged mainly depends on where the supplier and the customer are located.
💡 Aishira Explains
Imagine you and your friend order food online. The total bill is the same, but the payment can happen in different ways. Sometimes you both split the payment equally. Other times, one person pays the full amount first and settles it later. The amount paid doesn't change—only the method of sharing changes. GST works in a similar way. The tax itself remains GST, but the way it is collected and shared depends on the type of transaction.
🌍 Example
Suppose a business purchases office furniture from another business located in the same state.
The invoice may show:
CGST
SGST
Now suppose the same furniture is purchased from another state.
Instead of CGST and SGST, the invoice may show: IGST
Both invoices relate to GST, but the applicable component changes based on the nature of the transaction.
Why Does GST Have Different Types?
This is one of the most common questions beginners ask. "If GST is one tax, why isn't everything simply called GST?"
The answer lies in India's federal system of government. India has two major levels of government:
Central Government
State Governments
Both governments require tax revenue to perform their responsibilities.
For example:
The Central Government uses tax revenue for:
National highways
Defence
Railways
Airports
National welfare schemes
State Governments use tax revenue for:
Schools
Hospitals
State roads
Police services
Local development projects
Before GST was introduced, both governments collected different indirect taxes separately. When GST replaced many of those taxes, the government wanted to create one unified tax system while ensuring that both the Centre and the States continued to receive their rightful share of tax revenue. This is why GST was divided into different components instead of creating completely separate taxes.
💡 Aishira Explains
Imagine two siblings running a family shop together. Every day, the shop earns money. Instead of one sibling keeping all the earnings, they decide to divide the income according to an agreed arrangement. The shop still earns one total amount, but the money is shared between both owners. Similarly, GST is one tax, but its revenue is shared between different governments according to the GST rules.
How Is the Correct GST Type Decided?
The GST component applicable to a transaction mainly depends on the location of the supplier and the customer.
In simple words, the government first checks one important question: Are the supplier and the customer located in the same State or Union Territory, or are they located in different States or Union Territories?
The answer to this question determines which GST component will generally apply. This brings us to two important types of GST transactions.
Two Types of GST Transactions
Every GST transaction generally falls into one of these two categories.
1. Intra-State Supply
The word "Intra" means within. When the supplier and the customer are located in the same State or the same eligible Union Territory, the transaction is generally treated as an Intra-State Supply.
For such transactions:
CGST and SGST are generally charged together.
In certain eligible Union Territories, UTGST is charged instead of SGST.
🌍 Example
Suppose a stationery shop in Patna, Bihar sells office supplies to a business in Gaya, Bihar. Since both businesses are located in Bihar, the transaction is generally treated as an Intra-State Supply.
The invoice would usually include:
CGST
SGST
2. Inter-State Supply
The word "Inter" means between. When the supplier and the customer are located in different States or Union Territories, the transaction is generally treated as an Inter-State Supply. In such cases, IGST is generally charged instead of CGST and SGST separately.
🌍 Example
Suppose a computer dealer in Mumbai, Maharashtra sells a laptop to a business located in Patna, Bihar. Since the supplier and customer are located in different States, the transaction is generally treated as an Inter-State Supply.
The invoice would usually include:
IGST
instead of:
CGST
SGST
Quick Comparison: Intra-State vs Inter-State Supply
| Basis | Intra-State Supply | Inter-State Supply |
|---|---|---|
| Meaning | Supplier and customer are in the same State or eligible Union Territory | Supplier and customer are in different States or Union Territories |
| GST Charged | CGST + SGST (or CGST + UTGST, where applicable) | IGST |
| Number of GST Components | Two | One |
Easy Memory Trick
You don't need to memorise lengthy GST provisions. Just remember these two simple rules:
✅ Same State = CGST + SGST
✅ Different States = IGST
For eligible Union Territories: ✅ Same Union Territory = CGST + UTGST
This single trick can help you answer many beginner-level GST questions correctly.
What Is CGST?
After understanding that GST has four different components, let's begin with the first one. CGST is the first component of GST that applies to certain transactions within India. But what exactly does it mean?
CGST = Central Goods and Services Tax
CGST (Central Goods and Services Tax) is the portion of GST that belongs to the Central Government of India. It is generally charged when a transaction is an Intra-State Supply, that is, when the supplier and the customer are located in the same State. In such cases, the applicable GST is usually divided into two equal parts:
CGST
SGST
While both appear on the same invoice, CGST represents the Central Government's share of the GST collected.
💡 Aishira Explains
Imagine two friends jointly own a café.At the end of the day, the café earns ₹10,000. Instead of one friend taking the entire amount, they decide to divide it equally. The café still earned one total income, but each owner receives their agreed share. CGST works in a similar way. When GST is collected on an eligible intra-state transaction, one part is allocated to the Central Government, while the other part goes to the State Government.
🌍 Example
Suppose a clothing store in Jaipur, Rajasthan sells garments worth ₹20,000 to another business located in Jaipur. Applicable GST Rate = 18% Since both businesses are located in the same State, this is generally treated as an Intra-State Supply. Instead of charging a single 18% GST, the invoice would generally show:
CGST = 9%
SGST = 9%
The customer still pays 18% GST in total, but the tax is divided into two equal components.
Where Does the CGST Money Go?
Many beginners believe that businesses earn the GST they collect from customers. This is one of the biggest misconceptions. Businesses do not keep the GST collected from customers as their income. Instead, they collect the tax on behalf of the government and deposit it according to the applicable GST provisions. The CGST portion is ultimately credited to the Central Government. The supplier simply acts as an intermediary for collecting the tax.
💡 Aishira Explains
Think of a courier company. When you hand over a parcel, the courier company doesn't become the owner of the parcel. Its job is simply to deliver it to the correct destination. Similarly, when a business collects CGST, it does not own that money. Its responsibility is to collect the tax from customers and deposit it with the government as required under the GST law.
When Is CGST Charged?
CGST is generally charged when:
The supplier and the customer are located in the same State.
The transaction is treated as an Intra-State Supply under the GST law.
GST is applicable on the goods or services supplied.
Whenever these conditions are satisfied, CGST is generally charged along with SGST.
🌍 Example
Suppose a furniture dealer in Lucknow, Uttar Pradesh sells office chairs to a business located in Kanpur, Uttar Pradesh. Since both businesses are in the same State, the invoice would generally include:
CGST
SGST
There would normally be no IGST because the transaction has not crossed a State boundary.
How Is CGST Calculated?
Calculating CGST becomes easy once you know the applicable GST rate. For most Intra-State Supplies, the total GST rate is generally divided equally between CGST and SGST.
Formula = CGST = Total GST Rate ÷ 2
🌍 Example
Suppose a business sells goods worth ₹50,000. Applicable GST Rate = 18% The GST would generally be divided as follows:
| Particulars | Amount |
|---|---|
| Value of Goods | ₹50,000 |
| CGST (9%) | ₹4,500 |
| SGST (9%) | ₹4,500 |
| Total GST | ₹9,000 |
| Invoice Value | ₹59,000 |
Although the customer pays ₹9,000 as total GST, the invoice separately shows the Central Government's share and the State Government's share.
Key Features of CGST
Let's quickly summarise the important characteristics of CGST.
| Feature | Description |
|---|---|
| Full Form | Central Goods and Services Tax |
| Collected By | Central Government |
| Applicable On | Intra-State Supplies |
| Charged Along With | SGST (or UTGST in certain eligible Union Territories) |
| Purpose | Represents the Central Government's share of GST |
Common Misconceptions About CGST
Many beginners misunderstand how CGST works. Let's clear up a few common myths.
❌ Myth 1: CGST Is an Extra Tax
Reality: CGST is not an additional tax. It is simply one part of the total GST charged on an eligible intra-state transaction.
❌ Myth 2: Businesses Keep the CGST They Collect
Reality: Businesses collect CGST on behalf of the government. The tax does not become part of the business's income.
❌ Myth 3: CGST Is Charged on Every Transaction
Reality: CGST generally applies only to Intra-State Supplies. For many inter-state transactions, IGST is generally applicable instead.
What Is SGST?
While CGST represents the Central Government's share, SGST represents the State Government's share.
Let's understand it in detail.
SGST = State Goods and Services Tax
SGST (State Goods and Services Tax) is the portion of GST that belongs to the State Government.
It is generally charged on Intra-State Supplies, where both the supplier and the customer are located in the same State. For most intra-state transactions, CGST and SGST are charged together on the same invoice. While they appear as separate entries, they together make up the total GST applicable to the transaction.
💡 Aishira Explains
Imagine a city organizes a large cultural festival. The Central Government and the State Government both contribute towards making the event successful. Similarly, when GST is collected on an eligible intra-state transaction, the tax is shared between the Central Government (CGST) and the State Government (SGST). Both governments receive their respective share, even though the customer pays one total GST amount.
🌍 Example
Suppose a bakery in Patna, Bihar sells cakes worth ₹10,000 to a café located in Gaya, Bihar.
Applicable GST Rate = 12%
Since both businesses are located in Bihar, the transaction is generally treated as an Intra-State Supply. The invoice would usually show:
CGST = 6%
SGST = 6%
The customer pays 12% GST in total, but the tax is divided equally between the Central Government and the Bihar Government.
Where Does the SGST Money Go?
Just like CGST, the supplier does not keep the SGST collected from customers. The supplier collects the tax on behalf of the government and deposits it according to the applicable GST provisions. The SGST portion is credited to the State Government where the transaction is taxable under the GST law.
💡 Aishira Explains
Think of a school collecting examination fees. The school may collect the money from students, but it doesn't necessarily keep the entire amount. Part of the fee may be transferred to the examination board responsible for conducting the exams. Similarly, businesses collect SGST from customers but deposit it with the government as required under GST law.
When Is SGST Charged?
SGST is generally charged when:
The supplier and the customer are located in the same State.
The transaction is treated as an Intra-State Supply.
GST is applicable to the goods or services supplied.
Whenever these conditions are satisfied, SGST is generally charged along with CGST.
🌍 Example
Suppose an electronics dealer in Ahmedabad, Gujarat sells a laptop to a business located in Surat, Gujarat. Since both businesses are within Gujarat, the invoice would generally include:
CGST
SGST
There would normally be no IGST because the supply takes place within the same State.
Why Are CGST and SGST Usually Equal?
Many beginners notice that the CGST and SGST amounts on an invoice are often exactly the same. This is because, for most Intra-State Supplies, the applicable GST rate is generally divided equally between the Central Government and the State Government.
For example:
| Total GST Rate | CGST | SGST |
|---|---|---|
| 5% | 2.5% | 2.5% |
| 12% | 6% | 6% |
| 18% | 9% | 9% |
| 28% | 14% | 14% |
This equal distribution ensures that both governments receive their respective share of the GST collected on intra-state transactions.
CGST vs SGST
Although both taxes are charged together, they are credited to different governments.
| Basis | CGST | SGST |
|---|---|---|
| Full Form | Central Goods and Services Tax | State Goods and Services Tax |
| Tax Goes To | Central Government | State Government |
| Applicable On | Intra-State Supply | Intra-State Supply |
| Charged Along With | SGST | CGST |
One important thing to remember is that both taxes are collected together, but they are accounted for separately.
Reading an Invoice with CGST and SGST
Whenever you receive a GST invoice for an Intra-State Supply, you will generally find two separate GST entries.
Invoice Example
| Particulars | Amount |
|---|---|
| Value of Goods | ₹25,000 |
| CGST (9%) | ₹2,250 |
| SGST (9%) | ₹2,250 |
| Total Invoice Value | ₹29,500 |
Although the invoice displays two GST components, the customer pays one final amount. The separate breakup simply shows how the GST is distributed between the Central Government and the State Government.
Common Misconceptions About SGST
Let's clear up a few common myths.
❌ Myth 1: SGST Is a Separate Additional Tax
Reality: SGST is not an extra tax. It is one part of the total GST applicable to an eligible intra-state transaction.
❌ Myth 2: Every State Has a Different SGST Rate
Reality: The applicable GST rate is prescribed under GST law. For an intra-state transaction, that rate is generally divided equally between CGST and SGST.
❌ Myth 3: SGST Is Charged on Inter-State Supplies
Reality: SGST generally applies only to Intra-State Supplies. For many inter-state transactions, IGST is generally charged instead.
What Is IGST?
So far, we've learned that when a transaction takes place within the same State, GST is generally divided into CGST and SGST. But what happens when the supplier and the customer are located in different States or Union Territories? In such cases, GST works differently. Instead of charging CGST and SGST separately, the supplier generally charges IGST.
Let's understand why.
IGST = Integrated Goods and Services Tax
IGST (Integrated Goods and Services Tax) is the GST component that generally applies to Inter-State Supplies. An Inter-State Supply occurs when the supplier and the customer are located in different States or Union Territories, subject to the provisions of the GST law. Unlike intra-state transactions, where GST is divided into two parts, IGST is charged as a single tax.
💡 Aishira Explains
Imagine you're sending a parcel from Bihar to Maharashtra. Instead of handing the parcel to two different courier companies, you give it to one courier service, which takes care of the entire journey and ensures it reaches the correct destination. IGST works in a similar way. Instead of charging two separate taxes, one integrated tax is collected first, and the government later distributes the revenue according to the GST settlement mechanism.
🌍 Example
Suppose a furniture manufacturer in Jaipur, Rajasthan sells office desks worth ₹50,000 to a business located in Patna, Bihar. Applicable GST Rate = 18%. Since the supplier and the customer are located in different States, the transaction is generally treated as an Inter-State Supply.
Instead of showing:
CGST = 9%
SGST = 9%
the invoice would generally show:
IGST = 18%
The total GST remains 18%, but it is charged under a single heading.
Why Was IGST Introduced?
Many beginners wonder: "Why can't the government simply charge CGST and SGST for every transaction?"
The answer lies in the movement of goods and services between different States. If every inter-state transaction were charged with CGST and SGST, it would become difficult to determine which State should receive the State's share of the tax. To simplify this process, the GST system introduced IGST. It allows GST to be collected as a single integrated tax, after which the government settles the appropriate share with the concerned governments under the GST framework. This makes tax collection more organised and reduces complexity in inter-state trade.
💡 Aishira Explains
Imagine two friends living in different cities decide to split the cost of an online purchase. Instead of each paying the seller separately, one friend pays the entire amount first. Later, the second friend transfers their share. This makes the payment process much simpler. Similarly, IGST simplifies tax collection when a transaction involves different States.
When Is IGST Charged?
IGST is generally charged when:
The supplier and the customer are located in different States or Union Territories.
The transaction is treated as an Inter-State Supply under the GST law.
GST is applicable to the goods or services supplied.
For many inter-state transactions, IGST replaces CGST and SGST.
🌍 Example
Suppose a software company located in Bengaluru, Karnataka provides software services to a business in Kolkata, West Bengal. Since the supplier and the customer are located in different States, the invoice would generally include: IGST
There would normally be no separate CGST or SGST.
How Is IGST Calculated?
Calculating IGST is very simple. Unlike intra-state transactions, where GST is divided into two equal parts, IGST is charged as one combined tax.
Formula = IGST = Applicable GST Rate × Taxable Value
🌍 Example
Suppose a wholesaler in Delhi sells electrical equipment worth ₹1,00,000 to a retailer in Lucknow, Uttar Pradesh.
Applicable GST Rate = 18%
The invoice would generally appear as follows:
| Particulars | Amount |
|---|---|
| Value of Goods | ₹1,00,000 |
| IGST (18%) | ₹18,000 |
| Total Invoice Value | ₹1,18,000 |
Notice that the invoice contains only one GST component—IGST.
Same GST Rate, Different Structure
One common misunderstanding is that IGST means paying more GST. This is not true. The GST rate generally remains the same. Only the way it is shown on the invoice changes.
Let's compare.
| Transaction | GST Rate | GST Charged |
|---|---|---|
| Purchase within the same State | 18% | CGST 9% + SGST 9% |
| Purchase from another State | 18% | IGST 18% |
The customer still pays 18% GST. The only difference is how the tax is classified.
Online Shopping and IGST
Many people purchase products through online marketplaces. A common question is: "Does every online purchase attract IGST?"
The answer is No. The applicable GST depends on the location of the supplier, the place of supply, and the applicable GST provisions—not simply on whether the purchase was made online.
Example 1
Seller → Bihar
Buyer → Bihar
GST Generally Charged:
CGST
SGST
Example 2
Seller → Tamil Nadu
Buyer → Bihar
GST Generally Charged:
IGST
Example 3
Seller → Delhi
Buyer → Assam
GST Generally Charged:
IGST
This shows that the location of the supplier and the customer plays a much bigger role than the platform through which the goods or services are sold.
Common Misconceptions About IGST
Let's clear up a few common myths.
❌ Myth 1: IGST Is Charged Only on Imported Goods
Reality: IGST is generally applicable to Inter-State Supplies within India as well. It is not limited only to imports.
❌ Myth 2: IGST Means Paying More Tax
Reality: The applicable GST rate generally remains the same. Only the tax structure changes from CGST + SGST to IGST.
❌ Myth 3: IGST and CGST Are Charged Together
Reality: For many inter-state transactions, IGST is charged instead of CGST and SGST.
What Is UTGST?
By now, you've learned about:
CGST – Central Government's share of GST.
SGST – State Government's share of GST.
IGST – GST charged on most inter-state supplies.
But there's one more component of GST that often confuses beginners—UTGST. Many people assume that every Union Territory uses UTGST. That's not correct. UTGST applies only in certain eligible Union Territories under the GST law.
UTGST = Union Territory Goods and Services Tax
UTGST (Union Territory Goods and Services Tax) is the GST component that generally applies to Intra-Territory Supplies in certain Union Territories. It represents the Union Territory's share of GST. Whenever an eligible transaction takes place within the same Union Territory, GST is generally divided into:
CGST
UTGST
instead of:
CGST
SGST
In other words, UTGST performs a role similar to SGST, but only in certain Union Territories where the GST law provides for its application.
💡 Aishira Explains
Think of SGST and UTGST as two different routes leading to the same destination. If a business operates in a State, GST is generally divided into:
➡️ CGST + SGST
If the business operates in certain eligible Union Territories, GST is generally divided into:
➡️ CGST + UTGST
The purpose remains the same—sharing GST revenue—but the component used depends on where the transaction takes place.
🌍 Example
Suppose a bakery located in Chandigarh supplies cakes worth ₹20,000 to a café also located in Chandigarh. Applicable GST Rate = 12% Since both businesses are located in the same eligible Union Territory, the invoice would generally show:
CGST = 6%
UTGST = 6%
Instead of:
CGST
SGST
Where Does UTGST Apply?
UTGST generally applies to certain Union Territories that are administered under the Union Territory Goods and Services Tax Act, 2017.
Some commonly cited examples include:
Andaman and Nicobar Islands
Chandigarh
Dadra and Nagar Haveli and Daman and Diu
Lakshadweep
For eligible intra-territory supplies in these Union Territories, GST is generally divided into:
CGST
UTGST
Why Doesn't Every Union Territory Use UTGST?
This is one of the biggest misconceptions among beginners. People often think: "If a place is called a Union Territory, it must use UTGST."
However, the GST framework is slightly different. Some Union Territories have their own legislative arrangements for GST administration. As a result, they generally follow CGST + SGST instead of CGST + UTGST for intra-territory supplies. This is why not every Union Territory uses UTGST.
💡 Aishira Explains
Imagine two schools belonging to the same education board. Although both schools follow similar academic rules, one school has its own local management committee while the other is directly managed by the central office. Because of this difference, certain administrative procedures may vary. Similarly, Union Territories do not all follow the same GST structure.
Which Union Territories Generally Do Not Use UTGST?
Some Union Territories generally follow CGST + SGST for intra-territory supplies because of their constitutional or legislative arrangements.
Examples include:
Delhi (National Capital Territory of Delhi)
Puducherry
Jammu & Kashmir*
For beginners, the most important point to remember is: Not every Union Territory uses UTGST.
Always check the applicable GST provisions before assuming that UTGST applies.
Note: GST provisions may be amended over time. Always refer to the latest government notifications or legal provisions for current applicability.
UTGST vs SGST
Since both taxes represent the local government's share of GST, beginners often confuse them. The easiest way to understand the difference is through this comparison.
| Basis | SGST | UTGST |
|---|---|---|
| Full Form | State Goods and Services Tax | Union Territory Goods and Services Tax |
| Applicable In | States | Certain eligible Union Territories |
| Charged With | CGST | CGST |
| Represents | State Government's share | Union Territory's share under the GST framework |
Although their names are different, their purpose is broadly similar—they represent the local share of GST in eligible intra-state or intra-territory transactions.
Reading an Invoice with UTGST
Let's look at a simple invoice example.
Invoice Example
| Particulars | Amount |
|---|---|
| Value of Goods | ₹30,000 |
| CGST (9%) | ₹2,700 |
| UTGST (9%) | ₹2,700 |
| Total GST | ₹5,400 |
| Total Invoice Value | ₹35,400 |
Here, the customer pays 18% GST in total. Instead of splitting it into CGST + SGST, the invoice shows CGST + UTGST because the transaction takes place within an eligible Union Territory.
Common Misconceptions About UTGST
Let's clear up a few common myths.
❌ Myth 1: Every Union Territory Uses UTGST
Reality: Only certain eligible Union Territories use UTGST. Some Union Territories generally follow CGST + SGST.
❌ Myth 2: UTGST Is an Extra Tax
Reality: UTGST is not an additional tax. It simply replaces SGST for eligible intra-territory transactions.
❌ Myth 3: UTGST and SGST Are Charged Together
Reality: A transaction generally involves either SGST or UTGST, depending on where it takes place—not both together.
Quick Comparison of All Four GST Components
| GST Type | Full Form | Generally Used For | 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 settled as per GST law |
| UTGST | Union Territory Goods and Services Tax | Intra-Territory Supply in certain eligible Union Territories | Union Territory's share under the GST framework |
This table provides a quick overview and is useful for revision before exams.
How to Identify the Correct GST Type
Now that you understand all four components of GST—CGST, SGST, IGST, and UTGST—the next question is: "How do I know which GST type should be charged for a particular transaction?"
This is one of the most practical aspects of GST. Whether you're a student solving exam questions, an accountant preparing invoices, or a business owner issuing bills, you must know how to identify the correct GST type. Fortunately, the process is much simpler than it seems.
Step 1: Ask One Simple Question
Before looking at GST rates or invoice values, ask yourself this question: Are the supplier and the customer located in the same State or Union Territory, or in different States or Union Territories?
The answer to this single question helps determine which GST component generally applies. In most common transactions, this is the first step in identifying the correct GST type.
💡 Aishira Explains
Imagine you're planning to travel. The first thing you check isn't the ticket price—it's the destination. Similarly, before identifying the GST component, you first identify where the supplier and customer are located. Once you know the locations, choosing the applicable GST becomes much easier.
A Simple Decision Rule
You don't need to memorise long GST provisions. Follow this simple decision flow.
Supplier & Customer
│
▼
Are they in the same State/
eligible Union Territory?
│ │
Yes No
│ │
▼ ▼
CGST + SGST IGST
(or CGST +
UTGST where
applicable)
This flow works for most beginner-level GST questions and helps you quickly identify the applicable GST component.
Practical Scenarios
Let's apply this rule to some real-life situations.
Scenario 1: Local Purchase
A stationery shop in Patna, Bihar sells notebooks to a coaching institute in Gaya, Bihar.
Supplier: Bihar
Customer: Bihar
Since both are located in the same State, the transaction is generally treated as an Intra-State Supply.
GST Generally Charged
CGST
SGST
🌍 Example
Invoice Value = ₹10,000 ; Applicable GST Rate = 18% ; Invoice would generally show:
CGST = 9%
SGST = 9%
Scenario 2: Purchase from Another State
A furniture manufacturer in Jaipur, Rajasthan supplies office tables to a company in Patna, Bihar.
Supplier: Rajasthan
Customer: Bihar
Since the supplier and customer are located in different States, this is generally treated as an Inter-State Supply.
GST Generally Charged
IGST
🌍 Example
Invoice Value = ₹50,000
Applicable GST Rate = 18%
Invoice would generally show:
IGST = 18%
There would generally be no separate CGST or SGST.
Scenario 3: Service Within the Same State
GST doesn't apply only to goods. Many taxable services are also covered under GST. Suppose an interior designer based in Lucknow, Uttar Pradesh provides office renovation services to a business also located in Lucknow. Since both parties are in the same State, the invoice would generally include:
CGST
SGST
The fact that the transaction involves a service instead of goods doesn't change the basic rule.
Scenario 4: Online Software Subscription
Suppose a company located in Karnataka provides accounting software to a business registered in Bihar. Although the software is delivered online, the supplier and customer are located in different States. The transaction is generally treated as an Inter-State Supply.
GST Generally Charged
IGST
This shows that GST rules apply to both goods and many taxable services.
Does Online Shopping Always Mean IGST?
Many people believe that every online purchase attracts IGST. This is a common misconception.
The applicable GST depends on factors such as:
Location of the supplier
Place of supply
Applicable GST provisions
—not simply on whether the purchase was made online.
For example:
| Supplier | Customer | GST Generally Charged |
|---|---|---|
| Bihar | Bihar | CGST + SGST |
| Delhi | Bihar | IGST |
| Tamil Nadu | Assam | IGST |
The platform through which you place the order is not the deciding factor. The supplier's location and the applicable GST rules are far more important.
Understanding the Place of Supply
While learning GST, you'll often come across the term Place of Supply. Many beginners find it confusing. In simple words, the Place of Supply is an important GST concept that helps determine which type of GST should generally be charged.
It plays a key role in deciding whether a transaction is treated as:
Intra-State Supply, or
Inter-State Supply
For many everyday business transactions, identifying the place of supply is straightforward. However, for certain services, imports, exports, and special transactions, the GST law contains detailed place-of-supply rules. As a beginner, you don't need to memorise all those provisions right now. For now, simply remember: The Place of Supply is one of the important factors used to determine whether CGST + SGST or IGST generally applies.
💡 Aishira Explains
Think of the Place of Supply as the "address" used by the GST system to determine where a transaction belongs. Just as a courier company needs the correct delivery address before sending a parcel, the GST system uses the place of supply to determine the applicable GST component. Without this concept, deciding the correct GST type would often become difficult.
Common Mistakes Beginners Make While Identifying GST Types
Understanding the four components of GST is only the first step. The next challenge is using the correct GST type in real-life situations. Many students and new business owners make small mistakes because they focus on memorising abbreviations instead of understanding the logic behind GST. Let's look at some of the most common mistakes and learn how to avoid them.
Mistake 1: Thinking IGST Means Imported Goods Only
This is one of the biggest misconceptions among beginners. Many people believe that IGST is charged only on imported goods. That's not correct. IGST generally applies whenever a transaction is treated as an Inter-State Supply, even if both businesses are located within India.
💡 Aishira Explains
Suppose a business in Maharashtra sells office chairs to a company in Karnataka. The goods never leave India. Even then, since the supplier and customer are in different States, the transaction generally attracts IGST. So, IGST is not limited to imports.
Mistake 2: Believing Every Union Territory Uses UTGST
Another common misunderstanding is that every Union Territory follows the UTGST system. In reality, only certain eligible Union Territories use UTGST. Some Union Territories have different constitutional or legislative arrangements and generally follow CGST + SGST for intra-territory supplies. Always verify the applicable GST provisions instead of assuming that every Union Territory uses UTGST.
Mistake 3: Assuming IGST Means Higher Tax
Some beginners become worried when they see IGST on an invoice because they think it means paying extra tax. This is incorrect. The GST rate generally remains the same. Only the way the tax is shown on the invoice changes.
For example:
| Situation | GST Rate | Invoice Shows |
|---|---|---|
| Purchase within the same State | 18% | CGST 9% + SGST 9% |
| Purchase from another State | 18% | IGST 18% |
In both cases, the customer pays 18% GST. The difference is only in the classification of the tax, not the amount of tax.
Mistake 4: Ignoring the Supplier's Location
Some people decide the GST type only by looking at the customer's location. However, GST generally depends on both the supplier's location and the applicable place of supply rules. Ignoring either factor can result in selecting the wrong GST component.
🌍 Example
Suppose two businesses are located in different States. Even if the customer is registered under GST, the transaction may generally attract IGST because the supplier and customer are located in different States. This is why businesses carefully verify customer details before issuing invoices.
Mistake 5: Confusing CGST and SGST with Separate Taxes
Some beginners think: "First CGST is charged, and then SGST is added as another tax."
This is not how GST works. CGST and SGST are simply two equal components of the same GST for an eligible intra-state transaction. The customer pays one total GST amount, but the invoice separately displays each government's share.
Practical Tips for Students and Beginners
Now that you know the common mistakes, let's look at a few habits that can make learning GST much easier.
1. Understand Before You Memorise
Don't try to remember only the abbreviations. Instead, understand:
What each GST component means.
When it is generally used.
Why it is charged.
Once the logic is clear, remembering the names becomes much easier.
2. Always Check the Locations First
Whenever you solve a GST question, first identify:
Supplier's location
Customer's location
This simple habit helps you determine the applicable GST type in many common situations.
3. Read Real GST Invoices
The best way to become comfortable with GST is by reading actual invoices.
Observe details such as:
Supplier's name and address
Customer's name and address
GSTIN
Invoice number
Taxable value
GST breakup
Total invoice amount
The more invoices you read, the easier GST concepts become.
🌍 Example
The next time you receive a GST invoice while shopping or dining at a restaurant, take a moment to check:
Is the GST divided into CGST and SGST?
Or is IGST charged?
Try identifying why that particular GST component has been used. This small exercise will strengthen your understanding of GST.
4. Practice with Everyday Transactions
You don't need special accounting software to learn GST. You can practise using everyday examples such as:
Restaurant bills
Grocery invoices
Electronics purchases
Mobile phone bills
Business invoices
Ask yourself:
Is it an Intra-State Supply?
Is it an Inter-State Supply?
Which GST component is generally applicable?
Learning becomes much more effective when connected to real-life situations.
Quick Revision Tricks
Before we end this chapter, here are a few simple memory tricks.
Remember These Four Lines
✅ CGST = Central Government's Share
✅ SGST = State Government's Share
✅ IGST = Generally for Inter-State Supplies
✅ UTGST = Generally for Certain Eligible Union Territories
Remember This Rule
Same State → CGST + SGST
Different States → IGST
Eligible Union Territory → CGST + UTGST
This simple rule answers a large number of beginner-level GST questions.

Frequently Asked Questions (FAQs)
1. What are the four types of GST in India?
The four types of GST are:
CGST (Central Goods and Services Tax)
SGST (State Goods and Services Tax)
IGST (Integrated Goods and Services Tax)
UTGST (Union Territory Goods and Services Tax)
Each component applies in different situations depending on the nature of the transaction.
2. When are CGST and SGST charged?
CGST and SGST are generally charged when the supplier and the customer are located in the same State, making the transaction an Intra-State Supply.
3. When is IGST applicable?
IGST is generally applicable when goods or services are supplied between different States or Union Territories, making the transaction an Inter-State Supply, subject to the GST provisions.
4. What is UTGST?
UTGST is the Union Territory Goods and Services Tax. It generally applies to eligible intra-territory transactions in certain Union Territories and is charged along with CGST instead of SGST.
5. Is the GST rate different for IGST?
No. The applicable GST rate generally remains the same. The difference lies in how the tax is charged.
For example:
Intra-State Supply → CGST + SGST
Inter-State Supply → IGST
6. Does GST apply only to goods?
No. GST applies to many taxable goods as well as taxable services, subject to the provisions of the GST law.
