Difference Between CGST and SGST with Examples (2026)

Every Indian invoice has the CGST and SGST printed side by side. They are two separate charges that add up to the total GST rate you're supposed to pay. May do not know what the difference between CGST and SGS is, and why the government splits the tax into two parts.

This guide explains both tax components, the CGST SGST difference, and how GST is applied to invoices.

What is GST?

India's Goods and Services Tax came into effect under the GST Act, 2017. It replaced the Central Excise, VAT, Service Tax, and CST. It's a destination-based, multi-stage tax on the supply of all goods and services in the country. This means that the tax revenue goes to the respective state where the goods or services are actually consumed, not where they're produced or sold.

The GST framework has four components:

• CGST
• SGST
• IGST
• UTGST

Which ones apply to a transaction depends entirely on whether it crosses a state border. For all traders, understanding the difference between CGST, SGST, IGST, and UTGST is important for correct invoicing and GST return filing.

What is CGST?

CGST refers to the Central Goods and Services Tax. The Central Government applies CGST on the intra-state supply of all goods and services. In other words, CGST is applied when both the supplier and the buyer are in the same state.

The revenue from CGST goes entirely to the Central Government. Rates are set by the GST Council and have various slabs depending on the category of goods or services.

What is SGST?

The State Government collects the State Goods and Services Tax or SGST on all intra-state transactions. The SGST revenue stays entirely with the state government where the supply takes place.

You must understand that both rates will always be the same. If CGST is 9%, SGST will also be 9%. The main difference between SGST and CGST is who collects and retains the revenue.

CGST vs SGST (Comparison Table)

The CGST and SGST difference becomes clearer when you compare them side by side. Here's a comparison table for the two:

What is IGST?

IGST or Integrated Goods and Services Tax also applies to interstate supply of goods and services, as well as imports into India. When a supplier in one state sells to a buyer in another state, the transaction has IGST applied instead of CGST or SGST.

The IGST rate is equal to the combined CGST and SGST rate for the same product category. So a product attracting 9% CGST + 9% SGST will have an 18% IGST. The Central Government collects IGST and then settles the state's share with the destination state.

Difference Between IGST, CGST, and SGST

The difference between CGST, SGST, and IGST comes down to several factors. Here's a clear comparison:

The CGST SGST difference from IGST is simple. CGST and SGST apply together on intra-state sales, while IGST applies alone on inter-state sales. They never appear on the same invoice for the same transaction.

GST Calculation With Examples

Let us now take a look at the difference between CGST, SGST and IGST with examples:

Example 1: Intra-state sale (CGST + SGST apply)

A furniture dealer in Pune, Maharashtra, sells goods worth ₹50,000 to a buyer who is also in Maharashtra. The applicable GST rate is 18%.

Example 2: Inter-state sale (IGST applies)

The same Pune dealer sells goods worth ₹50,000 to a buyer in Bengaluru, Karnataka. GST rate remains 18%.

The final invoice amount is the same. The difference between SGST CGST and IGST is mainly administrative.

When CGST + SGST Apply

Although there is a difference between SGST and CGST, they are often charged together. This happens on transactions where the place of supply and the supplier are in the same state.

Situations where CGST and SGST apply together:

• A manufacturer in Delhi sells goods to a retailer in Delhi.

• A service provider registered in Tamil Nadu provides services to a client also in Tamil Nadu.

• An e-commerce seller in Mumbai delivers to a customer in Mumbai.

• A freelancer in Hyderabad, Telangana, invoices a company also registered in Telangana.

The 50:50 split between CGST and SGST is always valid regardless of the GST slab involved.

When IGST Applies

IGST replaces both CGST and SGST when the transaction is inter-state. It can apply in the following situations:

• Supply of goods or services from one state to another state.
• Import of goods into India (at the point of customs entry).
• Supply to or by SEZ (Special Economic Zone) units or developers.
• Supplies made by a person outside India to someone in India (digital services, online platforms).

What is UTGST?

UTGST stands for Union Territory Goods and Services Tax. It applies instead of SGST in union territories that don't have their own legislature. Union territories with their own legislature apply SGST instead of UTGST because they have state assemblies.

For the other five non-legislative UTs, UTGST functions exactly like SGST. It is applicable alongside CGST on intra-UT transactions, and the revenue goes to the respective UT administration. In other words, the main UTGST and CGST SGST difference is completely structural.

Input Tax Credit Rules Under GST

Input Tax Credit (ITC) allows a registered business to reduce the GST it pays on purchases by the GST it collects on sales. This prevents taxes from piling up at every stage of the supply chain.

A business can claim ITC if:

• It holds a valid tax invoice
• Has actually received the goods or services
• Has filed its GST returns
• Has paid the supplier

The ITC utilisation order follows a specific sequence:

• CGST credit can be used to offset CGST liability first, then IGST liability.
• SGST credit can be used to offset SGST liability first, then IGST liability.
• IGST credit can be used to offset IGST first, then CGST, and then SGST.

Common GST Mistakes Businesses Make

Even businesses that understand the difference between CGST and SGST can make many mistakes. Here’s what you must avoid:

• Do not charge IGST on a local sale just because the buyer’s billing address is in another state. Always follow the place of supply rules in the IGST Act to decide the correct tax.
• Do not use CGST credit to pay SGST dues. These two credits are separate and cannot be set off against each other.
• Do not miss the deadline to claim ITC for a financial year. If you claim it late, the credit may lapse.
• Do not show GST as one combined amount on the invoice. Always show CGST and SGST separately, each at the correct rate.

Conclusion

Understanding the difference between CGST and SGST is very important for any GST-registered business. Both taxes apply simultaneously to every transaction within the state. When transactions cross state borders, IGST applies at the full rate instead. And in non-legislature union territories, SGST gets replaced by UTGST.
