Frequently Asked Questions
What is the difference between CGST, SGST, and IGST?
CGST (Central) and SGST (State) are charged when the buyer and seller are in the same state. IGST (Integrated) is charged for sales across different states. The total tax amount remains the same.
What does 'Add GST' vs 'Remove GST' mean?
'Add GST' means your entered amount doesn't include tax yet (Exclusive). 'Remove GST' means the amount already includes tax, and you want to find the base price (Inclusive).
Is this updated with current Standard GST rates?
Yes, it uses the standard Standard GST slabs: 3%, 5%, 12%, 18%, and 28%.
