GST changed restaurant billing forever when it was introduced in India, and the rules have been refined several times since. In 2026, GST compliance isn't optional — it's enforced, audited, and directly affects your restaurant's reputation and finances. The good news: the right restaurant billing software handles GST automatically, turning a complex compliance requirement into a one-click report.
How GST Works for Restaurants in India
Restaurant GST in India is applied based on whether the restaurant has air conditioning, alcohol service, and its registration type. Here's the current rate structure:
| Restaurant Type | GST Rate | ITC Available? |
|---|---|---|
| Non-AC restaurant (no alcohol) | 5% (2.5% CGST + 2.5% SGST) | No |
| AC restaurant or with alcohol licence | 5% (2.5% CGST + 2.5% SGST) | No |
| Hotels with room tariff above ₹7,500/night | 18% (9% CGST + 9% SGST) | Yes |
| Outdoor catering | 18% (9% CGST + 9% SGST) | Yes |
| Takeaway / packaged food (restaurant) | 5% (without ITC) | No |
| Zomato / Swiggy delivery (restaurant side) | 5% collected by platform | No |
Note: GST rates and rules may be updated by the GST Council. Always verify with a qualified CA for your specific situation.
What Your Restaurant Billing Software Must Handle
1. Automatic Tax Calculation Per Item
Different items on your menu may attract different tax rates — especially if you serve both food and beverages including alcohol. Your billing software must apply the correct GST rate to each line item automatically, without requiring manual entry by staff.
2. Correct Invoice Format
A GST-compliant restaurant invoice must include: your business name and GSTIN, place of supply, invoice number and date, HSN/SAC code for food services, itemised amounts, applicable taxes (CGST + SGST or IGST), and total amount. Your POS should generate this format by default on every bill.
3. B2B vs B2C Invoice Handling
When a corporate client provides their GSTIN at checkout, the invoice must show their GSTIN and the full tax breakdown for their ITC claim. Your POS must support GSTIN capture at the time of billing and generate the correct B2B invoice format.
4. GSTR-1 Report Export
Every GST-registered restaurant must file GSTR-1 monthly or quarterly. Your billing software must be able to export a summary of all invoices in the correct format — ideally with a one-click export that your accountant or CA can upload directly to the GST portal.
5. Credit Note Management
When a customer is issued a refund or discount after an invoice is raised, a credit note must be issued with the correct tax reversal. Your POS should handle this without requiring manual journal entries.
6. Aggregator TCS Compliance
If your restaurant receives orders through Zomato or Swiggy, they collect TCS (Tax Collected at Source) at 1% under Section 52 of the CGST Act. Your billing software should track these separately so you can claim TCS credit accurately.
Common GST Mistakes Restaurants Make
Using a Generic Billing Tool
Many small restaurants use generic GST billing tools not built for food service. These tools often miss restaurant-specific requirements like table-wise billing, split bill handling, or delivery platform reconciliation — leading to compliance gaps.
Wrong HSN/SAC Codes
Restaurant services are classified under SAC code 996331 (restaurant service with AC) or 996332 (restaurant service without AC). Using the wrong code on your invoices can lead to notices during GST audits.
Manually Calculating Taxes
Manually applying GST on a calculator creates errors — especially during peak hours when bills are raised quickly. This is the single most common cause of GST mismatches. Automate it completely.

Cloud-based restaurant billing software has a key advantage for GST compliance: automatic updates. When the GST Council changes rates or introduces new filing requirements, a cloud system is updated centrally — you don't need to download patches or call a vendor. On-premise systems require manual updates that many small restaurant owners delay, creating compliance risk.
For GST compliance alone, cloud POS is the strongly recommended choice in 2026.
The Bottom Line
GST compliance doesn't need to be a burden. The right restaurant billing software handles everything automatically — from calculating taxes to generating audit-ready reports. The key is choosing software built specifically for Indian food service, not a generic billing tool with a GST sticker on it.
