What GST Rate Should You Apply in Invoices? Complete Business Guide

What Is a GST Rate?

A GST rate is the percentage of tax applied to goods or services sold by a business. The GST rate depends on the product category, service type, and government tax classification.

In India, common GST slabs include:

• 0% GST: Essential goods and exempt products
• 5% GST: Daily-use products and selected items
• 12% GST: Certain goods and services
• 18% GST: Most products and services
• 28% GST: Luxury and high-tax products

Businesses must select the applicable GST rate based on the product or service they are selling.

How to Choose the Correct GST Rate for Your Invoice? 1. Identify Your Product or Service Category

Every product and service has an HSN (Harmonized System of Nomenclature) or SAC (Service Accounting Code). These codes help determine the applicable GST rate.

Before generating an invoice, businesses should verify the correct HSN or SAC code to avoid tax calculation mistakes.

2. Check the Applicable GST Slab

After identifying the product category, select the correct GST percentage. Different products under the same business may have different GST rates.

For example:

• Grocery items may have different GST rates depending on the product.
• Electronic products generally fall under higher GST slabs.
• Professional services usually follow specific GST rates.

3. Understand CGST, SGST, and IGST

The GST rate is divided based on the transaction location:

Within the Same State:

• CGST (Central GST)
• SGST (State GST)

Example:
If GST is 18%, the invoice will show:

• CGST: 9%
• SGST: 9%

Between Different States:

• IGST (Integrated GST)

Example:
An interstate sale with 18% GST will include:

• IGST: 18%
