HSN, SAC, and GST on items
Put the correct HSN or SAC and tax group on each item so invoices auto-calculate CGST, SGST, or IGST and GST reports stay clean.

How this looks in TiBook
How to
- 1Open an item (or start Add item) and find HSN / SAC.
- 2For goods, enter the HSN code. For services, enter the SAC code your CA expects on the bill.
- 3Pick the tax group (for example GST 18%) from the dropdown. Groups are built in Settings → Tax.
- 4Set sale and purchase prices with the with tax / without tax toggle so the line rate matches what you type at the counter.
- 5Save the item. New sales and purchase invoices pull HSN, SAC, and rate from the item — not from a single company-wide default.
- 6On an invoice, place of supply and party type decide whether lines split into CGST+SGST or IGST.
Why item-level tax
Different products often carry different GST rates. TiBook totals tax from each line, which is what GSTR-style summaries expect.
Unregistered or non-GST bills
Leave tax off on the document, or use items with a zero-rate group. You can still keep HSN on the item for when you register.
Use tax groups everywhere — avoid typing a one-off percentage on every invoice.
If lookup on company GSTIN filled your legal name, item HSN is still your job — TiBook does not guess product codes.
