India e-invoicing: GST rate slabs and HSN codes
The GST slabs
India's GST is organised into rate slabs rather than a single standard rate: 0, 5, 12, 18, and 28 percent. Most services and a large share of goods sit at 18 percent. Essential and mass-consumption items sit at 5 or 12 percent, while a 28 percent slab covers automobiles and certain luxury goods.
HSN and SAC codes
Every line on a GST invoice needs a classification code: an HSN code for goods or a SAC code for services. The code drives the rate, so getting it right is the same task as getting the rate right. The code and the slab travel together on the line.
What e-invoicing requires
GST e-invoicing applies to businesses above a turnover threshold. In scope businesses report each B2B invoice to the Invoice Registration Portal, which returns an IRN and a signed QR code. The tax may be split into CGST, SGST, or IGST depending on the place of supply. Amounts round to 2 decimal places in INR.
| Category | Tax code | Rate | Typical items |
|---|---|---|---|
| IT & professional services | S | 18% | Software, consulting, legal, accounting |
| Standard goods (18%) | S | 18% | Electronics, machinery, most manufactured goods |
| Standard goods (12%) | S | 12% | Processed food, apparel above threshold, select goods |
| Essential goods (5%) | S | 5% | Packaged food staples, footwear, mass-use items |
| Luxury & sin goods (28%) | S | 28% | Automobiles, aerated drinks, select luxury goods |
| Restaurant services | S | 5% | Non-AC restaurant dining (no input credit) |
| Hotel accommodation (standard) | S | 12% | Mid-tariff room nights |
| Nil-rated / exempt goods | Z | 0% | Fresh produce, unbranded staples, certain books |
| Exported goods & services | Z | 0% | Zero-rated exports (with or without LUT) |
| Healthcare services | E | 0% | Hospital and clinical services |
| Education services | E | 0% | School and recognised education |
| Reverse charge supply | AE | 18% | Recipient self-accounts under RCM |
Line item calculations you can check by hand
Each example uses the same rules the tool applies: net equals quantity times unit price, tax equals net times the rate, and the line total is net plus tax.
Questions about invoice line items and tax rates
How do I calculate VAT on an invoice line?
Multiply the net price (quantity times unit price) by the tax rate to get the tax amount. For a SAR 1,000 net line at 15%, the VAT is SAR 150, making the line total SAR 1,150. This tool does the same calculation for every line and adds them up for you.
What tax category codes do e-invoicing mandates require?
Most mandates use S for the standard rate, Z for zero-rated, E for exempt, AA for a reduced rate, AE for reverse charge, and O for supplies not subject to tax. Each line on the invoice must carry the correct code alongside the rate and the calculated tax amount.
How do I classify my product or service?
Pick the category that best matches what you are selling, or type it and let the tool detect it. For the final compliant file you will also need an item classification code such as an HS, GPC, HSN, SAC, or UNSPSC code, which the Complyance platform applies during generation.
Can I have multiple tax rates on one invoice?
Yes. Each line carries its own tax category and rate. The invoice summary then shows a tax breakdown by rate, listing the taxable amount and the tax for each rate separately, which is exactly what most tax authorities expect on a multi-rate invoice.
What happens if I use the wrong tax rate?
An incorrect rate produces an incorrect tax amount and a non-compliant invoice. Tax authorities can impose fines for non-compliant e-invoices, and your customer may be unable to claim the input tax. Confirm the category and rate for each item before you send.
Does the tool save or send my invoice data?
No. The builder runs entirely in your browser. Your line items are never sent to a server, and nothing is stored once you close the tab. Copy and CSV export both happen on your own device.
Which countries does the line item builder support?
Saudi Arabia, the UAE, Malaysia, Germany, France, and India, each with its own rates, tax codes, and currency. Switch country from the sidebar and the categories reload.
Is the line item builder really free?
Yes. Building line items, viewing the tax breakdown, copying the summary, and exporting CSV are all free with no signup. Generating a signed, submittable e-invoice file such as ZATCA UBL 2.1 or Peppol is the paid step handled by the Complyance platform.
