Question 1

How to extract GST from MRP (Inclusive formula)?

Accepted Answer

To extract GST backwards from a Maximum Retail Price (MRP) or GST-inclusive total, use the reverse GST formula: Net Base Amount = (Total Gross Amount × 100) ÷ (100 + GST Rate), and GST Extracted = Total Gross Amount − Net Base Amount. For example, if an invoice or MRP is ₹1,180 with 18% GST: Net Base Amount = (1,180 × 100) ÷ 118 = ₹1,000, and GST extracted is ₹180 (split into ₹90 CGST and ₹90 SGST).

Question 2

What is the difference between CGST, SGST, and IGST?

Accepted Answer

For intra-state transactions (seller and buyer within the same State/UT), GST is split equally into Central GST (CGST, 50%) and State/UT GST (SGST/UTGST, 50%). For inter-state transactions (seller and buyer in different States), 100% Integrated GST (IGST) is levied by the Central Government and subsequently apportioned to the destination consumer state. The total tax liability remains identical regardless of whether supply is intra-state or inter-state.

Question 3

Is GST calculated before or after discount?

Accepted Answer

Under Section 15(3) of the Central Goods and Services Tax (CGST) Act, trade discounts recorded on the invoice are deducted before calculating GST. Tax is levied strictly on the net transaction value. For example, if an item has an MRP of ₹1,000 and a 10% trade discount (₹100) is provided on the invoice, 18% GST applies to the discounted taxable base of ₹900 (GST = ₹162, total = ₹1,062), not on ₹1,000.

Question 4

What is the GST rate on gold in India?

Accepted Answer

Gold bars, coins, bullion, and jewelry attract a special statutory GST rate of 3% (HSN Code 7113). In addition, jewelry making charges (job work) attract 5% GST (SAC 9988) if billed separately. By contrast, rough industrial diamonds attract 0.25% GST, and cut and polished diamonds attract 1.5% GST.

Question 5

What is the reverse GST formula and how does a reverse GST calculator work?

Accepted Answer

A reverse GST calculator extracts the original pre-tax value from a gross total price. The mathematical formula is: Net Amount = Gross Amount ÷ (1 + (GST Rate ÷ 100)). The tax component is Gross Amount − Net Amount. This reverse extraction is standard for consumer retail products where the price tag already includes tax.

Question 6

How does Input Tax Credit (ITC) work with GST calculations?

Accepted Answer

Input Tax Credit (ITC) prevents cascading taxation by allowing registered businesses to offset the GST paid on inward purchases against the GST collected on outward sales. For example, if you purchase raw materials for ₹10,000 + 18% GST (₹1,800 ITC) and sell the finished goods for ₹15,000 + 18% GST (₹2,700 Output GST), you pay only the net difference of ₹900 (₹2,700 − ₹1,800) in cash to the government.

Question 7

What are the standard GST slabs in India?

Accepted Answer

India operates primarily under four statutory GST slabs: 5% (essential goods, medicines, economy rail/air travel), 12% (processed foods, business computers, hotel rooms up to ₹7,500), 18% (standard rate for IT/telecom, commercial services, capital goods), and 28% (automobiles, air conditioners, aerated beverages, cement, luxury goods). In addition, special rates apply to precious metals (3% on gold/silver) and basic food staples are exempt (0%).
