IGST Full Form: Meaning, Rate and Calculation IGST stands for Integrated Goods and Services Tax.

The IGST full form is Integrated Goods and Services Tax. It generally applies to inter-state supplies of goods and services, as well as imports, subject to applicable GST provisions. IGST helps manage taxation when a supply involves different states or union territories under India's Goods and Services Tax framework.

Understanding IGST is essential for business owners, traders, and professionals who manage GST invoices, tax calculations, and compliance.

What Is IGST in GST?

IGST stands for Integrated Goods and Services Tax. It generally applies when a supply qualifies as an inter-state supply under GST law. Unlike eligible intrastate supplies, which generally attract CGST and SGST or UTGST, inter-state supplies are generally taxed under IGST.

For example, if a business in Rajasthan sells taxable goods to a customer in Maharashtra, IGST will generally apply, depending on the place-of-supply rules and the nature of the transaction.

What Is the Meaning of IGST?

The IGST meaning refers to the tax levied on eligible inter-state supplies of goods and services under the Integrated Goods and Services Tax Act, 2017. The Central Government collects IGST and apportions the revenue between the Centre and the destination state according to applicable provisions. This supports the destination-based taxation system under GST. Businesses should determine the correct place of supply before deciding whether IGST or the applicable intrastate tax components apply.

What Is the IGST Rate?

The IGST rate depends on the classification of the goods or services and their applicable GST rate. Common GST slabs include 5%, 12%, 18%, and 28%, although exemptions and special rates may apply to particular supplies. 

For example, if an eligible inter-state supply is taxable at 18%, the applicable IGST rate would generally be 18% of its taxable value. Businesses should verify the current rate for their specific goods or services before preparing an invoice.

When Is IGST Applicable?

IGST generally applies to inter-state supplies and imports, subject to the relevant provisions of GST law. Applicability depends on factors such as the supplier's location, place of supply, and type of transaction.

For example, a Jaipur-based business supplying taxable goods to a business in Maharashtra will generally charge IGST if the transaction qualifies as an inter-state supply.

Imports and exports have specific GST provisions, so businesses should assess these transactions separately rather than assuming that the same rules apply to every case.

What Is the Difference Between IGST, CGST and SGST?

The main difference between these taxes is how they apply to a supply.

• IGST: Generally applies to inter-state supplies and is collected by the Central Government.
• CGST: Generally applies to eligible intrastate supplies alongside SGST or UTGST.
• SGST: Generally applies alongside CGST to eligible intrastate supplies and represents the state component of GST.

For an eligible intrastate supply taxed at 18%, the tax would generally be split into 9% CGST and 9% SGST. For an eligible inter-state supply taxed at the same total rate, 18% IGST would generally apply.

To understand each component in detail, read our guides on the CGST full form, meaning and calculation and the SGST full form, meaning and calculation.

How Is IGST Calculated?

IGST is calculated by multiplying the taxable value of a supply by the applicable IGST rate.

Example:

• Taxable value: ₹10,000
• Applicable IGST rate: 18%
• IGST amount: ₹10,000 × 18% = ₹1,800
• Total invoice value: ₹11,800

This example assumes the supply is taxable at 18% and no other adjustments apply.
