The Exchange Offer Trap
Why a trade-in is barter and not a discount, the order Rule 27 sets for valuation, and the Rules’ own worked example on a phone.
A 10-page guide for electronics and appliance retailers going into the 2026 festive season. Why an exchange offer is taxed on your price without exchange and not on what the customer pays, what the September 2025 rate drop changed, how to track serials and warranties, and what the e-waste rules actually require of you.

Every big-ticket line that moved from 28% to 18%, why screen size stopped mattering on televisions, and what to check in your item master.
Capturing the unit against the invoice so a return is a lookup rather than an argument, plus display-unit tracking.
Where the money actually leaks: exchanges billed as discounts, accessories on the wrong rate, display units sold off the books.
Working backwards from Diwali on 8 November, with Dhanteras as the heaviest single day for appliances.
Credit notes versus warranty replacements, and what the E-Waste Rules 2022 actually require of a retailer.

Explore Petpooja InvoiceBring your old television, get ₹6,000 off a new one. Every electronics shop in India runs some version of it through Diwali. Almost all of them bill it as a discount. It is not a discount.
Section 15(1) of the CGST Act values a supply at the transaction value, but only where the price is the sole consideration. In an exchange it is not: the customer hands over money and an old appliance, and the appliance is part of what you are paid.
Section 15(4) then sends you to the prescribed rules, and Rule 27 of the CGST Rules sets the order. Open market value comes first. For something you sell every day, that is simply your normal price without the exchange.
Rule 27 illustrates it with almost exactly this transaction. A new phone supplied for ₹20,000 along with an old phone traded in, where the price without exchange is ₹24,000, has an open market value of ₹24,000. GST is charged on ₹24,000, not on the ₹20,000 the customer paid.
So on a ₹42,000 television with a ₹6,000 exchange allowance, the taxable value stays ₹42,000. The tax is ₹7,560, not ₹6,480. Bill it as a discount and you are short ₹1,080 on that sale, on every exchange, through your busiest six weeks.
The contrast matters because a genuine discount does work the other way. A discount given at or before the time of supply and recorded on the invoice reduces taxable value under Section 15(3)(a). Credit notes behave differently again. Three things that look alike on a price tag and diverge completely in your GST returns.
There is a second thing worth knowing this year. On 22 September 2025 the 28% slab was abolished and televisions, air conditioners, refrigerators, washing machines and dishwashers moved to 18%. That is a ten point drop on the lines that carry your festive volume, and anyone still pricing off a pre-September cost sheet is wrong. The reform is set out by the Press Information Bureau and the current entries are on the CBIC rate schedule.
Here's a preview of what you'll get inside:
The GST shortfall on a single ₹42,000 television billed as a ₹6,000 discount instead of an exchange. Multiply by every exchange sale you make in six weeks.

They do not. On a ₹42,000 set with a ₹6,000 allowance, tax is on ₹42,000. Staff need a one-line answer ready, because this gets asked at the counter all week.
The 28% slab was abolished on 22 September 2025. If a refrigerator or air conditioner is still on the old rate in your item master, you are over-collecting from customers and holding money that is not yours. Check the current entry on the CBIC rate schedule.
Sets above 32 inches used to attract 28% while smaller ones were 18%. They all sit at 18% now, so a size-based rule in your system is at best doing nothing.
Tied to the invoice, the unit history is one lookup. Kept in a notebook, a warranty claim in March becomes an hour of searching and an unhappy customer. This is one of the practical differences between manual billing and POS software.
The most common stock discrepancy in electronics retail, and it only surfaces at the annual count when nobody remembers the sale. It sits alongside the other inventory mistakes retail stores make.
Under the E-Waste (Management) Rules 2022, in force from 1 April 2023, the regulated entities are producers, manufacturers, refurbishers, dismantlers and recyclers. CPCB's published FAQ does not list dealers and retailers as needing EPR registration. The 2016 Rules did cover dealers; the 2022 Rules narrowed it.
