• 18%: Most services, electronics, restaurants (standard rate)

GST Exclusive vs. GST Inclusive

• GST Exclusive: The displayed price does NOT include GST. You add GST on top. Formula: GST = Price × Rate/100. Total = Price + GST.
• GST Inclusive: The displayed price ALREADY includes GST. To find the base price: Base = Total / (1 + Rate/100). GST = Total - Base.

CGST and SGST

For intra-state (within the same state) transactions, GST is split equally between the Central Government (CGST) and the State Government (SGST). So 18% GST = 9% CGST + 9% SGST. For inter-state transactions, IGST (Integrated GST) is applied at the full rate.

Who Needs to File GST?

Businesses with an annual turnover exceeding ₹40 lakhs (₹20 lakhs for services) must register for GST. Freelancers providing services interstate must register regardless of turnover.
