What is the difference between CGST, SGST and IGST?

On a supply within one state the tax is split into Central GST (CGST) and State GST (SGST), each half the slab rate. On a supply between states the tax is a single Integrated GST (IGST) at the full rate. The total GST is the same in both cases.

How do I remove GST from an inclusive price?

Divide the gross amount by one plus the rate. For example a price of 1180 that includes 18 percent GST has a taxable value of 1180 divided by 1.18, which is 1000, so the GST is 180. Choose Remove GST to do this.

Which GST rate applies to my product or service?

The rate depends on the HSN code for goods or the SAC for services. The common slabs are 0, 5, 12, 18 and 28 percent. Use the CBIC rate finder or the GST portal to confirm the slab for a specific item.

Yes. The GST Council revises rates and classifications from time to time. Treat this calculator as an example and verify the current slab against the official sources before filing.

How it works

The GST split behind the number

GST is charged on the taxable value at a slab rate. Where the supply stays within one state the tax splits into equal CGST and SGST halves. Where it crosses a state line the whole amount is IGST.

Slab rates

The common GST slabs are 0, 5, 12, 18 and 28 percent. The rate depends on the HSN code for goods or the SAC for services, so confirm the slab that applies to the specific supply.

CGST, SGST or IGST

An intra-state supply is taxed half as CGST and half as SGST. An inter-state supply is taxed as a single IGST at the full rate. The total tax is the same either way.

Inclusive or exclusive

When a price already includes GST, the taxable value is backed out as amount divided by one plus the rate. When it excludes GST, the tax is added on top. This tool does both.

Sources

GST rates and rules are set by the GST Council and administered by CBIC. Rates vary by HSN or SAC. Verify the applicable slab against the primary sources below.

Keep GST on your invoices, not on a spreadsheet

Rivane applies the right GST split to every invoice and keeps the tax ready for return time, so a filing figure is a report, not a recalculation.
