FAQ
What is GST?
GST (Goods and Services Tax) is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax that replaced numerous cascading taxes levied by central and state governments.
What are the different GST slabs explained?
Goods and services in India are broadly classified into 4 major tax slabs: 5%, 12%, 18%, and 28%. Essential items are either exempt or taxed at lower rates, while luxury goods attract the highest 28% slab along with additional cess in some cases.
What is the difference between CGST, SGST, and IGST?
CGST (Central) and SGST (State) are applied on intra-state sales (within the same state), splitting the GST equally. IGST (Integrated) is collected by the Centre for inter-state sales (between two different states).
How do I add GST to a base amount?
To add GST, multiply the original amount by the GST rate percentage and add the result to the original amount. The formula is: Total Amount = Base Amount + (Base Amount * GST Rate / 100).
How do I remove GST from a total amount?
To calculate the base price from a GST-inclusive amount, divide the total amount by (1 + GST Rate/100). The formula is: Base Amount = Total Amount - (Total Amount * (100 / (100 + GST Rate))).
What is the Reverse Charge Mechanism (RCM)?
Under normal circumstances, the supplier of goods or services pays GST. Under Reverse Charge Mechanism, the liability to pay GST falls on the recipient or buyer instead of the supplier.
How is GST calculated on services?
Most common services are taxed at a standard GST rate of 18%. This includes IT services, financial services, and telecom. Certain specific services may fall under the 5% or 12% brackets depending on government classifications.
What is Input Tax Credit (ITC)?
ITC is the backbone of the GST regime. It allows a business to reduce the tax it has already paid on inputs (purchases) from the tax it has to pay on outputs (sales), thereby avoiding double taxation.
