Frequently Asked Questions
How do I calculate GST on an amount?
To calculate GST on an amount, multiply the base amount by the GST rate and divide by 100. For example, if your base amount is Rs. 10,000 and GST rate is 18%, the GST amount would be 10,000 x 18 / 100 = Rs. 1,800. The total amount would be Rs. 11,800. For intra-state transactions, this GST is split equally into CGST (9%) and SGST (9%).
What is the difference between CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) are charged equally on intra-state transactions (within the same state). IGST (Integrated GST) is charged on inter-state transactions (between different states) and is equal to CGST + SGST. For example, if GST rate is 18%, intra-state transactions have 9% CGST + 9% SGST, while inter-state transactions have 18% IGST.
How do I calculate GST from an inclusive amount?
To calculate GST from a tax-inclusive amount, use this formula: Base Amount = Inclusive Amount x 100 / (100 + GST Rate). For example, if the inclusive amount is Rs. 11,800 and GST is 18%, then Base Amount = 11,800 x 100 / 118 = Rs. 10,000, and GST = Rs. 1,800.
What are the current GST rate slabs in India?
India has six GST rate slabs: 0% (essential items like milk, fruits, vegetables), 3% (gold, silver, platinum), 5% (packaged foods, footwear under Rs. 1000), 12% (processed foods, computers), 18% (most goods and services, electronics, capital goods), and 28% (luxury items, automobiles, tobacco). Some items also attract additional cess.
Is cess applicable on all GST calculations?
No, GST cess is not applicable on all items. Compensation cess is levied only on specific goods like luxury cars (1-22%), aerated drinks (12%), tobacco products (up to 290%), pan masala (60%), and coal (Rs. 400 per tonne). Most regular goods and services do not attract any cess.
