GST on Used Cars in India: The Dealer's Complete Guide
GST on used cars confuses a lot of dealers, and overcharging it can cost you sales while undercharging can cost you penalties. The good news: for most pre-owned dealers, the rules are simpler than they look, thanks to the margin scheme.
This guide explains when GST applies, how much, and how to bill it. (Rates and rules change, always confirm the current position for your case with a tax professional.)
When does GST apply to a used car?
- Private seller selling their own car → no GST (not a business supply).
- Registered dealer in the business of selling used cars → GST applies, usually under the margin scheme.
- Unregistered dealer (below the GST threshold) → no GST charged.
The margin scheme, the key idea
Under the margin scheme for second-hand goods, a registered dealer pays GST only on the margin, not the full sale value:
Margin = Sale price − Purchase price
If you bought a car for ₹5,00,000 and sell it for ₹5,20,000, GST is calculated on the ₹20,000 margin, not on ₹5,20,000. If you sell at a loss, the margin is nil and no GST is payable.
This exists so the same car isn't taxed in full again and again each time it resells. We break the mechanics down further in the margin scheme guide.
How to calculate it (worked example)
| Item | Amount |
|---|---|
| Purchase price | ₹ 5,00,000 |
| Sale price | ₹ 5,20,000 |
| Margin (taxable value) | ₹ 20,000 |
| CGST @ 9% | ₹ 1,800 |
| SGST @ 9% | ₹ 1,800 |
| Buyer pays | ₹ 5,23,600 |
The exact rate depends on the vehicle category and the prevailing notification, verify before you bill.
What this means for your invoice
- A margin-scheme invoice does not show input tax credit and charges GST on the margin only.
- You should not show the customer the full-value tax break-up as if GST applied to the whole price.
- See the correct used car invoice format for both GST and non-GST bills.
Conditions to keep the scheme valid
- You must not have claimed input tax credit on the purchase of that car.
- There should be no change to the nature of the goods (you're reselling the car, not parting it out).
- Keep clean purchase and sale records for every vehicle, your margin (and tax) is only as defensible as your paperwork.
Don't let billing slow you down
Switching between GST margin-scheme invoices and plain non-GST bills, deal after deal, eats time. Capturing the purchase price, sale price and vehicle details once, and letting the invoice compute the margin and tax, keeps every bill correct and fast. From there the same data flows into your sale letter and RTO forms.

Do I pay GST on the full price of a used car?
Registered dealers using the margin scheme pay GST only on their margin (sale price minus purchase price), not the full vehicle value. If the margin is negative, no GST is payable.
Does a private seller charge GST on a used car?
No. A private individual selling their personal car is not making a taxable supply in business and does not charge GST. GST applies to registered dealers in the business of selling vehicles.
Can I claim input tax credit under the margin scheme?
No. The margin scheme and input tax credit are mutually exclusive, if you bought the car without claiming ITC, you bill on margin. Confirm your specific case with a tax professional.
