Where are GST rates set in Tazk POS?
Open Settings → Taxes and GST. The Tax Rate list has one row per tax component: for each GST category, such as GST18, an INTER row for IGST at the full rate (sales to another state) and two INTRA rows for CGST and SGST at half the rate each (sales within your state). Click + to add a rate with its tax code, category, jurisdiction and percentage.

How do the rows fit together?
Each tax category has three rows. For GST18:
- 18 INTER — IGST 18%, charged when you sell to another state.
- 9 INTRA CGST + 9 INTRA SGST — charged together (18% in total) when you sell within your state.
Products carry a tax category (set in Product Master). When you bill, Tazk compares your location's state with the customer's and applies the INTER or INTRA rows of that category.
