Common questions

How do I add GST to a price?

Multiply the price by the rate and divide by 100: 18% GST on ₹10,000 is ₹1,800, so the total is ₹11,800.

How do I remove GST from an inclusive price?

Multiply by 100 and divide by 100 plus the rate: ₹11,800 including 18% GST is ₹11,800 × 100 ÷ 118 = ₹10,000 before GST, so the GST is ₹1,800.

What are the GST rates now?

Since 22 September 2025 the main rates are 5% and 18%, with 40% for a short list of luxury and sin goods, following the 56th GST Council meeting and CBIC Notification 9/2025-Central Tax (Rate), read on 12 October 2026. A few items keep special rates such as 3% and 0.25%. Check your product's HSN or SAC code for its rate.

What is the difference between CGST, SGST and IGST?

Within one state, GST is split equally into central GST and state GST, so 18% is 9% + 9%. Between states, the whole amount is integrated GST. The total tax is the same.

When is UTGST used instead of SGST?

In union territories without their own legislature, such as Chandigarh or Ladakh, the state half is called UTGST.

Why does my total differ by a paisa?

GST is rounded to the paisa here, and the CGST and SGST halves are rounded so that they add up exactly to the total GST. Your billing software may round per item instead.

Does it include cess?

No. Compensation cess and TCS are not included.

Is it free?

Yes, completely free, with no sign-up.
