When GST Stays Within One State: The Real Meaning of Intra-State Supply

GST looks straightforward on the surface, but its foundation rests on one basic classification — whether a supply is intra-state or inter-state. This single distinction decides which tax you charge, how much tax applies, and which government gets the revenue. Many small businesses unknowingly make errors here, not because they intend to evade tax, but simply because the concept feels abstract.

Understanding intra-state supply under GST is not just about theory. It directly affects invoicing, tax compliance, returns, and even penalties. Let’s break it down gently, with relatable examples and practical clarity, so it finally makes sense.

What Does “Intra-State” Mean in GST?

In simple terms, “intra-state” supply refers to the supply of goods or services where the location of the supplier and the place of supply are within the same state or Union Territory.

To put it plainly:

• Seller and buyer may be different
• Goods or services move or are delivered
• But everything happens within the same state or UT

This is the most common type of supply for local businesses.

Legal Definition of Intra-State Supply

Under GST law, the supply of goods or services within the same state or union territory is treated as intra-state supply when:

• The supplier of goods or services and the place of supply are within the same state, and
• It is not classified as an inter-state supply

In such cases, GST is levied on the supply of goods and services within the same state or union territory in the form of CGST and SGST (or UTGST).

Taxes Applicable on Intra-State Supply

This is where things become practical.

When a supply is intra-state:

• CGST (Central GST) is charged
• SGST (State GST) or UTGST is charged
• IGST does not apply

Example

If a consultant in Jaipur provides services to a client also located in Jaipur:

• Services originate and are consumed in the same State
• CGST SGST are charged
• No IGST involved

How to Identify Intra-State Supply Correctly

The confusion usually comes from one question: “Which state matters — buyer’s or seller’s?”

The answer lies in two concepts:

1. Location of supplier
2. Place of supply

If both are in the same state, the supply becomes intra-state.

Intra-State Supply Exists When:

• Supplier’s location and place of supply are in the same state
• Services originate and are consumed in the same State or Union territory
• Goods are supplied and delivered within the same state

It doesn’t matter where payment comes from — location and place of supply matter more.

Common Examples of Intra-State Supply

Let’s make this real.

• A shop in Mumbai sells goods to a customer also in Mumbai
• A CA firm in Delhi provides services to a Delhi-based company
• A caterer supplies food within the same city
• An online seller delivers goods within the same state warehouse

In all these cases, the supply of goods or services is within the same state.

Intra-State Supply of Services – Special Focus

Services are where most mistakes happen.

A service is intra-state when:

• The supplier’s location and the place of supply is within the same state
• The service is performed, delivered, or consumed locally

For example, if a designer in Bangalore designs a logo for a Bangalore startup, the service:

• Originates in Karnataka
• Is consumed in Karnataka
• Qualifies as intra-state supply

Difference Between Intra-State and Inter-State (Quick Clarity)

Understanding intra-state becomes easier when you see the contrast.

Why Intra-State Classification Is So Important

Many businesses underestimate this.

Incorrect classification can lead to:

• Wrong tax collection
• Ineligible ITC claims
• Notices from GST department
• Interest and penalties

I’ve personally seen small traders receive notices just because they charged IGST instead of CGST SGST on a local invoice.

A small line item mistake can snowball into months of compliance stress.

Input Tax Credit (ITC) on Intra-State Supply

When you receive an invoice for intra-state supply:

• CGST credit can be used against CGST or IGST
• SGST credit can be used against SGST or IGST
• CGST and SGST cannot be cross-utilised directly

This makes correct tax breakup crucial for ITC planning.

Common Mistakes Businesses Make

Here are mistakes I see again and again:

• Assuming buyer’s billing address alone decides tax
• Ignoring place of supply rules for services
• Charging IGST for local sales
• Using wrong GST registration location
• Treating UTs the same as states without checking rules

All of these are avoidable with basic clarity on intra-state meaning in GST.

Practical Tip to Stay Compliant

Before raising any GST invoice, always ask:

• Where am I registered?
• Where is the place of supply?
• Are both in the same state or Union territory?

If the answer is yes — it’s intra-state, and CGST SGST apply.

Conclusion

Whenever the supplier’s location and the place of supply are in the same state, the supply becomes intra-state, and GST is levied accordingly within that state or union territory.

Once this foundation is clear, GST compliance becomes far less intimidating and far more manageable.
