A CNG bill for your vehicle must show the station name and address, the quantity in kilograms (kg), the rate per kg, the GST split (CGST + SGST), and the total amount paid. Unlike petrol and diesel, CNG is taxed under GST — so a valid receipt usually shows tax broken out. This guide gives you the exact format, a filled sample, and a free way to make one in two minutes.
Quick answer: what a CNG bill must include
- CNG station / outlet name, address and contact number
- GSTIN (15 digits) if the station is GST-registered
- Receipt number and date (and time, ideally)
- Vehicle number (useful for reimbursement)
- Quantity in kg and rate per kg
- Taxable value, CGST + SGST (CNG attracts GST)
- Total amount and payment mode (UPI / card / cash)
Mandatory fields (and why each one matters)
| Field | Example | Why it matters |
|---|---|---|
| Station name | Indraprastha Gas CNG Station | Identifies the supplier; required on a tax invoice |
| Address | Plot 12, Ring Road, New Delhi, Delhi 110024 | Establishes place of supply for GST |
| GSTIN | 07AAECD9012K1Z8 | Mandatory for registered stations; lets a business claim ITC |
| Receipt number | CNG-2026-08842 | Unique reference for your records and audit trail |
| Date & time | 01 Jun 2026, 9:15 AM | Required for the tax period and reimbursement claims |
| Vehicle number | DL 3C CD 4567 | Ties the spend to a specific vehicle for reimbursement |
| Quantity (kg) | 8.50 kg | CNG is sold by weight, not by litre |
| Rate per kg | ₹76.00 / kg | Basis for the taxable value |
| CGST & SGST | 2.5% + 2.5% | The GST split that applies to CNG (not to petrol/diesel) |
| Total amount | ₹646.00 | The amount actually paid |
| Payment mode | UPI / FASTag / Cash | Record-keeping and reconciliation |
Sample CNG bill (filled example)
Indraprastha Gas Limited — CNG Station Plot 12, Ring Road, New Delhi, Delhi 110024 · GSTIN: 07AAECD9012K1Z8 Receipt: CNG-2026-08842 · Date: 01 Jun 2026, 9:15 AM Vehicle: DL 3C CD 4567 · Customer: Priya Malhotra
| Description | Qty (kg) | Rate (₹/kg) | Amount (₹) |
|---|---|---|---|
| Compressed Natural Gas (CNG) | 8.50 | 76.00 | 646.00 |
| Taxable value | 615.24 | ||
| CGST @ 2.5% | 15.38 | ||
| SGST @ 2.5% | 15.38 | ||
| Total Amount | 646.00 |
Payment: UPI · Drive safe!
Note on the maths: at a 5% GST-inclusive pump price of ₹646.00, the taxable value works back to ₹615.24 and GST to ₹30.76 (₹15.38 CGST + ₹15.38 SGST). Many retail CNG receipts simply print the all-inclusive total per kg; if your station shows tax separately, the split will look like the sample above.
Why CNG is taxed differently from petrol and diesel
This is the detail most fuel guides miss. Petrol and diesel are currently outside GST — they attract central excise duty plus state VAT, which is why a petrol bill for reimbursement shows no CGST/SGST split. CNG, however, falls under GST, currently at 5% (2.5% CGST + 2.5% SGST) as of FY 2025–26.
That has two practical effects:
- A genuine CNG receipt can legitimately show a CGST + SGST breakup — a petrol/diesel receipt cannot.
- A GST-registered business can, in principle, claim input tax credit on CNG used for eligible business purposes, subject to the usual ITC conditions. (This is not possible on petrol/diesel, which sit outside GST entirely.) If you are filing these costs through work, our guide on how to claim fuel reimbursement from your employer walks through the policy and paperwork.
GST rates and slabs follow the CBIC GST rate notifications(opens in new tab). Because petroleum products are a politically sensitive category, their treatment can change — always confirm the current CNG slab before relying on a figure. The GST framework and item-wise rates are notified via the GST Council(opens in new tab), and the legal basis sits in the CGST Act on India Code(opens in new tab).
Honesty matters. A CNG bill is a record of fuel you actually bought. Recreating a lost receipt for a real refuelling — to support a genuine reimbursement or your own expense tracking — is fine. Fabricating purchases that never happened is fraud. For the full legal line, see can you create your own fuel bill.
How to create a CNG bill in 2 minutes
You do not need accounting software for a single receipt. Using the fuel bill generator:
- Pick the fuel bill template and set the fuel type to CNG (so the quantity reads in kg).
- Enter the station details — name, address and GSTIN (saved for next time).
- Add the refuel line — quantity in kg and rate per kg; the tool computes the total and, if GST is enabled, the CGST + SGST split.
- Add the vehicle number, date and payment mode so the bill is reimbursement-ready.
- Download a clean PDF to print or share on WhatsApp.
If you manage several vehicles, the same flow works for a diesel fleet record — only the unit and tax treatment change — and you can keep every refuel in one place by following our notes on fleet fuel expense tracking.

Common mistakes to avoid
- Billing in litres instead of kg — CNG is sold by weight; a receipt showing litres is an immediate red flag for any reimbursement team.
- Copying a petrol receipt format with no GST — CNG attracts GST, so a credible CNG bill usually shows CGST + SGST, not the excise/VAT structure of petrol.
- Using a fake or expired GSTIN — it invalidates the bill and blocks any input tax credit claim.
- Leaving off the vehicle number — most employers need it to tie the spend to an approved vehicle.
- Round-number quantities every time (exactly 10.00 kg, every trip) — real refuels are rarely so neat and look fabricated.
- Mismatched totals — the kg × rate plus GST must equal the printed total, or the bill won't reconcile.
