Frequently Asked Questions

What are CGST and SGST?

For sales within the same state (Intra-state), GST is split equally into Central GST (CGST) and State GST (SGST). For example, an 18% GST becomes 9% CGST and 9% SGST.

What about IGST?

If you are selling goods across state lines (Inter-state), the entire tax is collected as Integrated GST (IGST). The total percentage remains the same.

How do I extract GST from an MRP?

Maximum Retail Price (MRP) in India includes GST. Use the "Remove GST / Inclusive" option to find out exactly how much tax the government is collecting on that product.

Can I use custom percentages?

While the tool provides quick buttons for the standard slabs, you can manually type any percentage into the rate box if needed.

Can I do reverse GST calculations?

Yes, you can input a final total and the tool will show you the pre-tax base amount.

Does it support custom tax slabs?

Yes, you can select standard slabs (e.g., 5%, 12%, 18%) or enter a custom percentage.
