5. How do I remove GST from a price (Reverse GST Calculation)?

Answer: If a price is GST-inclusive, you can remove GST using this formula:

Base Price=GST-inclusive Price×100100+GST Rate\text{Base Price} = \frac{\text{GST-inclusive Price} \times 100}{100 + \text{GST Rate}}Base Price=100+GST RateGST-inclusive Price×100​

Example: If the GST-inclusive price is ₹1,180 and the GST rate is 18%,

Base Price=1180×100118=₹1,000\text{Base Price} = \frac{1180 \times 100}{118} = ₹1,000Base Price=1181180×100​=₹1,000

6. What is Input Tax Credit (ITC) and how is it calculated?

Answer: Input Tax Credit (ITC) allows businesses to reduce their GST liability by claiming credit for GST paid on purchases. It is calculated as:

ITC=GST paid on purchases−GST collected on sales\text{ITC} = \text{GST paid on purchases} - \text{GST collected on sales}ITC=GST paid on purchases−GST collected on sales

For example, if a business paid ₹5,000 GST on raw materials and collected ₹8,000 GST on sales, the net GST payable is:

GST Payable=₹8,000−₹5,000=₹3,000\text{GST Payable} = ₹8,000 - ₹5,000 = ₹3,000GST Payable=₹8,000−₹5,000=₹3,000
