How to Extract GST from Inclusive Price

If the price already includes GST, use this formula:

Base Price = Inclusive Price ÷ (1 + GST Rate/100)

Example: ₹1,180 at 18% GST → Base = 1180 ÷ 1.18 = ₹1,000. GST amount = ₹180.

Frequently Asked Questions
Who needs to register for GST?

GST registration is mandatory if annual turnover exceeds ₹40L (₹20L for special states) for goods, or ₹20L (₹10L for special states) for services. E-commerce sellers must register regardless of turnover.

What is Input Tax Credit (ITC)?

ITC allows businesses to reduce the GST they owe on sales by the amount of GST already paid on purchases. For example, if you paid ₹1,800 GST on raw materials and collected ₹3,600 GST on finished goods, you only pay ₹1,800 to the government.

What is the GST on gold and jewelry?

Gold and gold jewelry attract 3% GST. Making charges on jewelry are taxed at 5%. So total effective GST on gold jewelry is roughly 3% + 5% of making charges.

Is GST applicable on rent?

Residential rent is GST-exempt if the tenant is an individual for personal use. Commercial rent attracts 18% GST. If the landlord's total rental income exceeds ₹20L/year, GST registration is required.
