On an invoice, round the final tax to the rupee. Composition dealers charge no GST on the invoice and pay a flat rate on turnover instead.

How it is calculated

  1. Adding GST: tax = amount × rate; total = amount + tax.
  2. Removing GST: base = inclusive amount ÷ (1 + rate); tax = inclusive amount − base.
  3. Within the same state the tax is split equally into CGST and SGST. To another state the whole amount is IGST.
  4. The rate depends on the HSN or SAC code of the goods or service. We confirm the right rate before you invoice.

Indicative only. Rules change every year; we confirm before filing.
