What is GST (Goods and Services Tax)?

The Goods and Services Tax (GST) is an indirect value-added tax levied on the supply of goods and services in India. Introduced on July 1, 2017, GST replaced multiple central and state indirect taxes (excise duty, VAT, service tax) under a "One Nation, One Tax" framework.

Under GST, businesses collect tax at every supply stage and claim Input Tax Credit (ITC) on taxes paid during procurement, ensuring tax is levied only on value addition.

Key Tax Benefit:

Seamless Input Tax Credit (ITC) claimable across shipping & courier dispatches.

CGST vs SGST vs IGST Breakdown

CGST (Central GST)

SGST (State GST)

Collected by State Govt on Intra-State sales (equal to 50% of total GST rate).

IGST (Integrated GST)

Levied on Inter-State transactions (between two different states) and imports/exports.

How to Calculate GST: Formulas

Formula 1

GST Exclusive Calculation (Add Tax)

Use when tax is NOT included in base price.

GST Amount = (Base Amount × GST Rate) / 100

Total Amount = Base Amount + GST Amount

Formula 2

GST Inclusive Calculation (Extract Tax)

Use when total price already includes GST.

GST Amount = Total - [Total × {100 / (100 + Rate)}]

Base Amount = Total Amount - GST Amount
