Frequently Asked Questions About GST Tax Calculator
What is the difference between GST Exclusive and GST Inclusive?
GST Exclusive means the initial price does not include tax, so GST is added on top. GST Inclusive means the listed price already contains the tax, and you need to reverse-calculate the pre-tax base amount.
How are CGST and SGST calculated?
For intra-state transactions (within the same state), the total GST rate is divided equally into Central GST (CGST, 50%) and State GST (SGST, 50%).
