Tax setup (GST)
Configure your GSTIN, create tax categories and HSN codes, and understand how Acronix Books picks CGST + SGST vs IGST automatically.
Getting GST right starts with a few minutes of setup. Once configured, Acronix Books applies the correct tax to every invoice without you thinking about it.
Your GSTIN and state
Set your GSTIN and state on the company (see Creating your first company). Your state is what determines the tax split on every sale:
- Intra-state (customer in the same state) → CGST + SGST
- Inter-state (customer in a different state) → IGST
Acronix Books compares your state with the party's state on each invoice and applies the right combination automatically.
Tax categories and rates
A tax category bundles a GST rate (for example 0%, 5%, 12%, 18%, 28%). Create the categories your goods and services fall under, then attach the right category to each item.
| Item | HSN/SAC | Tax category |
|---|---|---|
| Cotton fabric | 5208 | GST 5% |
| Readymade garment (≤ ₹1000) | 6109 | GST 5% |
| Consulting service | 9983 | GST 18% |
HSN / SAC codes
Every item should carry its HSN (goods) or SAC (services) code. These codes:
- Print on the tax invoice as required.
- Roll up into the HSN summary of your GSTR-1.
Set it once on the item
Store the HSN code and tax category on the item master, not on each invoice. Every voucher then inherits them automatically, and your GSTR-1 HSN summary comes out clean.
Rounding and cess
Acronix Books handles per-line tax computation and invoice rounding consistently, so your invoice totals and your return summaries agree. Where a cess applies, add it to the relevant tax category.
Check your rates against current notifications
GST rates and HSN classifications change through CBIC notifications. Acronix Books applies whatever rate you configure — it's your responsibility (with your CA) to keep tax categories aligned with the current law.
