Qualify the stock before taxing the difference
For a registered dealer buying and reselling second-hand goods, rule 32(5) can value an eligible taxable supply at its positive selling-price less purchase-price difference. The goods must be resold as such or after minor processing that preserves their nature, and purchase ITC must not have been availed. Negative differences are ignored. This is a valuation method, not an exemption for all used goods or a general tax on business profit.
This guide, checked on 22 October 2026, addresses non-vehicle dealer inventory. The CBIC rules compilation, rule 32(1) and (5) supplies the rule; the CBIC margin-scheme flyer updated November 2022 and Ministry of Finance release of 15 July 2017 explain its application. Those older guidance dates do not establish a current product tax rate. Motor vehicles, repossession valuation and disposals of business capital assets require separate checks and are excluded from these examples.
Maintain a purchase-to-sale chain for every item
Assign a stock identifier at acquisition. Link the seller, purchase document, description, condition, agreed price and payment to the outward sale. When a supplier sells several used items as one lot, establish a defensible allocation from identifiable costs or other documented evidence before measuring individual resale margins. A convenient allocation chosen only after seeing which items made losses is weak evidence.
A purchase from a registered seller does not by itself answer whether purchase ITC has been availed. Reconcile the actual credit ledger, inward register and relevant tax documents. Conversely, buying from an unregistered person does not prove the item is used or that processing preserves its nature. Keep each eligibility test separate. Where purchase credit was taken, do not assume a later journal reversal automatically validates historical margin treatment; resolve the precise facts and applicable law before filing.
Taxable margin differs from commercial profit
Use the purchase price of the same goods rather than the shop’s total operating cost. Cleaning, minor repairs, storage, wages and rent can reduce accounting profit without becoming a further deduction in the sale-price minus purchase-price formula. The CBIC flyer specifically addresses repair or refurbishment value as part of the goods’ margin. Where processing changes the nature of what is sold, investigate eligibility first instead of merely adding more costs to the spreadsheet.
Apply the zero floor to the relevant supply. For separately sold identifiable goods, a loss on one sale should not reduce a positive margin on another. Summing all purchase and sale values for the month and taxing only the resulting net surplus can therefore understate value. Do not split or combine genuine supplies artificially: establish the contractual supply and item evidence before deciding the calculation unit.
Keep classification, invoicing and receipts distinct
Rule 32(5) does not prescribe a universal GST rate. Determine the actual goods classification, applicable rate, tax point and place of supply independently. All cases below deliberately assume sale figures exclusive of output GST; the first uses a hypothetical combined 18% only to demonstrate arithmetic. It is not a current rate claim for any named product. The remaining cases focus on taxable value so that no unsupported rate assumption enters them.
The register should reconcile commercial sales to the smaller margin-based taxable values with a transparent bridge. A customer payment, gateway deposit or ledger profit alone cannot reconstruct the purchase-price evidence. Preserve the gross commercial consideration and the statutory valuation working; do not hide part of the sale receipt as an unexplained non-taxable receipt. Check invoice presentation and return mapping for the actual transaction rather than assuming that a valuation option removes documentation duties.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: positive difference with an assumed rate
An eligible dealer buys a used item for ₹50,000 and sells it for ₹70,000 exclusive of output GST. No purchase ITC was availed. Taxable margin is ₹20,000. Assuming, solely for arithmetic, applicable combined GST of 18%, tax is ₹3,600. Commercial consideration before GST remains ₹70,000; the ₹20,000 is the special taxable value.
Illustrative example 2: a loss does not create a negative tax base
An eligible item costs ₹40,000 and is separately sold for ₹35,000 exclusive of output GST. The difference is minus ₹5,000, ignored under the rule. Margin value is zero. This is not a ₹5,000 credit available against another sale’s margin or a GST refund merely because the dealer lost money.
Illustrative example 3: two separate sales cannot be netted
Item A costs ₹50,000 and sells for ₹70,000; separately sold item B costs ₹40,000 and sells for ₹35,000. Positive taxable values total ₹20,000 + zero = ₹20,000. Net commercial surplus is only ₹15,000. Using ₹15,000 as the taxable margin would wrongly offset B’s ₹5,000 loss against A.
Illustrative example 4: minor repair expense does not reduce purchase-price margin
Assume an eligible used item bought for ₹30,000 undergoes ₹6,000 of minor repair without changing its nature, then sells for ₹50,000 exclusive of output GST. The taxable difference is ₹20,000, not ₹14,000. ₹14,000 is the surplus after that repair cost before other expenses. Any ITC treatment of the repair input itself needs a separate eligibility analysis; the example assumes no such credit adjustment.
Illustrative example 5: a supported lot allocation follows the sold item
A documented purchase lot contains five identical used units for ₹1,00,000, with equal condition and value supporting ₹20,000 purchase cost each. One unit sells separately for ₹28,000. Its margin is ₹8,000. Do not deduct the whole ₹1,00,000 against that first sale; the remaining ₹80,000 purchase allocation belongs to unsold stock.
Illustrative example 6: five separately sold units with different outcomes
Five eligible identifiable units cost ₹15,000 each. Three are separately sold for ₹18,000 each and two separately for ₹14,000 each. Taxable value is three × ₹3,000 plus two × zero = ₹9,000. Aggregate selling proceeds ₹82,000 less purchase costs ₹75,000 gives commercial surplus ₹7,000, which is not the rule’s taxable value for these five separate supplies.

Sixteen practitioner FAQs
1. Is this a composition scheme?
No. It is a conditional valuation method under rule 32.
2. Does every used-asset sale qualify?
No. Establish the dealer-stock conditions and any separately applicable capital-asset provisions.
3. Does the guide cover used motor vehicles?
No. Vehicle notifications and valuation issues require their own analysis.
4. Can the dealer resell after minor cleaning?
Potentially, if processing does not change the goods’ nature and all other conditions are met.
5. Does major transformation remain minor processing?
Do not assume so. Assess the actual goods before using the scheme.
6. Is purchase from an unregistered seller mandatory in the rule’s main text?
The main eligibility wording focuses on second-hand dealing, unchanged nature and no purchase ITC; do not replace those tests with seller status alone.
7. Can credit actually taken on the purchased goods be ignored?
No. The no-purchase-ITC condition is central.
8. Does a later credit reversal automatically settle an earlier incorrect return?
No. Resolve the historical facts and legal consequences before treating that as a cure.
9. Can repair costs reduce the purchase-price difference?
They are not an extra purchase-price deduction merely because they reduce profit.
10. Can rent and salaries be allocated to eliminate margin GST?
No. Commercial overhead allocation does not rewrite the rule’s valuation formula.
11. What happens to a negative difference?
It is ignored for margin valuation; it does not create a negative taxable value.
12. Can an unrelated loss item reduce a profitable item’s separately supplied margin?
No. Keep the calculations linked to the relevant supplies.
13. Can the full cost of a purchased lot be deducted against its first unit sold?
No. Support an appropriate allocation to the goods actually supplied.
14. Does the rule set an 18% rate for all used goods?
No. The rate in the first illustration is expressly hypothetical.
15. Are the examples tax-inclusive sale calculations?
No. Selling figures are exclusive of output GST to isolate margin valuation.
16. What evidence matters most in an audit?
A traceable item-level purchase and sale record, processing evidence and proof that purchase ITC was not availed.
