Mixed-Rate Jewellery Invoice Reconciliation: 3% + 5% + 18% GST on One Bill

A single retail jewellery invoice can carry three GST rates at once — gold at 3% under HSN 7113, making charges at 5% under the job-work entry of Notification 11/2017-CTR, and packaging or safety plates at 18%. Reconciling that bill across GSTR-1, the GL revenue split, and ITC accumulation on 18% inputs against 3% outputs is the single most consequential control in Indian jewellery finance.

Problem

A single retail jewellery invoice in India routinely carries three or four GST rates simultaneously — gold or silver at 3% under HSN 7113, making charges at 5% under the job-work entry of Notification 11/2017-CTR, diamond or precious-stone value at 0.25% under HSN 7102/7103, and ancillary items (presentation box, die, safety plate, security clasp) at 18% under general HSN codes. The customer-facing bill must show the split, the GSTR-1 filing must aggregate line-by-line into distinct tax-rate rows, the GL must recognise revenue and cost of goods sold across the same split, and Section 54(3) inverted-duty refund calculations must partition ITC between the 3% output supply and the 18% ancillary output supply. Retailers who blend rates informally over- or under-collect GST, misfile GSTR-1, and either lose the inverted-duty refund or invite a Section 74 audit notice at year-end.

How It's Resolved

Build a line-item classifier that assigns each invoice line to one of four rate buckets — 3% (jewellery HSN 7113 or silver), 5% (making charges as job-work services), 0.25% (diamond and precious stones HSN 7102/7103), and 18% (packaging, dies, safety plates, general HSN 7326 or 4819). Classify each ancillary line as either naturally bundled (composite supply, taxed at principal-supply rate 3%) or independently sellable (mixed supply, taxed at highest rate 18%) per Section 2(30) and Section 2(74). Aggregate lines into GSTR-1 tax-rate rows and reconcile against the trial-balance revenue by HSN. Split ITC on 18% inputs between goods used commonly for taxable and exempt supplies (Section 17(5)) and goods contributing to inverted-duty structure (Section 54(3) refundable). Cross-foot output tax collected to GSTR-3B output tax liability before month-end close.

Configuration

Item master with HSN code, rate flag (3% / 5% / 0.25% / 18%), composite-bundle indicator, and BIS HUID capture where applicable; making-charges service line with SAC code and 5% rate; diamond master with certification (IGI/GIA/HRD) reference and per-carat value; packaging and die master with 18% rate and Section 17(5) or 54(3) attribution flag; scheme master for discount treatment under Section 15(3); customer master with GSTIN (for B2B) and PAN (for jewellery above ₹2 lakh cash-consideration reporting under Rule 114B); karigar master with PAN and Section 393(1) Sl. 4 (194C) TDS rate flag; old-gold exchange indicator with unregistered-customer default and registered-customer alternate path.

Output

A monthly reconciliation pack: invoice-level tax-rate split by 3%, 5%, 0.25%, and 18%, aggregated to GSTR-1 tax-rate rows; GL revenue reconciliation by HSN with variance tolerance per line; ITC reconciliation split between fully utilisable (18% ancillary output supply), inverted-duty refundable (18% inputs against 3% jewellery output), and Section 17(5) restricted; Rule 89(5) refund working with turnover of inverted-rated supply, net ITC, and adjusted total turnover; karigar labour TDS reconciliation at Section 393(1) Sl. 4 rate against Form 26AS; per-invoice audit trail showing composite versus mixed classification and Section 15(3) discount treatment on old-gold exchange.

A national jewellery retailer’s controller opens the trial balance for the quarter ending 30 June 2026. Output tax collected on jewellery invoices reads ₹127.4 crore against consolidated sales of approximately ₹4,180 crore across 411 stores. The blended tax rate works out to 3.05% — surprisingly close to the base 3% on gold, meaning the retailer’s own numbers are asserting that making charges (which should have added 5% on roughly 12% of invoice value) and ancillary items (18% on maybe 2%) have somehow washed out. A closer look at the invoice-level extract tells a different story. Making charges have been informally rolled into the gold line on 62% of B2C bills across the network — the customer sees a single “gold value” and no separate 5% row, and the store system has been filing the whole invoice at 3%. The under-collected 2% on the making-charges portion works out to ₹6.2 crore of unrecognised GST liability for the quarter alone. This is mixed rate jewellery invoice GST reconciliation India at production scale, and the reconciliation discipline that resolves it is what separates a clean GSTR-1 filing from a Section 74 notice at year-end.

The reconciliation in one paragraph

A retail jewellery invoice for a finished piece is not one supply — it is three or four distinct supplies bundled together. The gold or silver metal is an article of jewellery under HSN 7113 (Notification 1/2017-CTR Schedule V) at 3%. The making charges billed by the karigar and passed through to the customer are job-work services in relation to jewellery manufacture under Entry 26 of Notification 11/2017-CTR at 5%. Diamond or precious-stone value falls under HSN 7102 or 7103 (Schedule VI) at 0.25%. Presentation boxes, dies used only for that piece, safety plates, security clasps, and any general-goods ancillary items fall under HSN 7326, 4819, or similar general codes at 18%. Section 15 of the CGST Act read with Section 8 requires each line to be taxed at its own rate unless the supply is composite (naturally bundled — taxed at the principal-supply rate) or mixed (independently sellable items sold at a single price — taxed at the highest rate). The retailer must issue an invoice that shows every tax-rate line separately, file GSTR-1 aggregating those lines into distinct tax-rate rows, recognise revenue in the GL by HSN, and split ITC on 18% inputs between fully utilisable and Section 54(3) inverted-duty refundable — every month, every store, every invoice.

What the retail jewellery invoice actually looks like in India

Walk into a large Tanishq store in a Bangalore mall on a Saturday afternoon. A customer selects a 22-carat diamond-studded gold ring — a wedding-collection piece with a certified 0.42-carat centre stone, four side stones, and a 6.8-gram gold setting. The store attendant swipes the piece across the tag reader, and the point-of-sale terminal builds the invoice line by line. The gold weight (6.8 grams) is multiplied by the day’s gold rate (roughly ₹7,220 per gram for 22-carat on this hypothetical day) to yield ₹49,096. The making charge is calculated at 12% of the gold value — ₹5,891. The certified diamond centre stone is valued at ₹78,000 per the certification. Side stones aggregate to ₹6,800. The presentation box is a hard-shell velvet-lined case that the store ordinarily sells for ₹350 to walk-in buyers who want an empty box for a personal transfer. A safety plate is soldered into the ring shank to prevent size loss — the plate is billed at ₹280.

The invoice the customer receives is a five-line document. Line 1: gold value ₹49,096 at HSN 7113 · 3% GST · CGST ₹737 · SGST ₹737 · line total ₹50,570. Line 2: making charges ₹5,891 at SAC 9988 · 5% GST · CGST ₹147 · SGST ₹147 · line total ₹6,185. Line 3: certified centre stone ₹78,000 at HSN 7102 · 0.25% GST · CGST ₹98 · SGST ₹98 · line total ₹78,196. Line 4: side stones ₹6,800 at HSN 7102 · 0.25% GST · CGST ₹9 · SGST ₹9 · line total ₹6,818. Line 5: safety plate ₹280 at HSN 7326 · 18% GST · CGST ₹25 · SGST ₹25 · line total ₹330. The presentation box is included at no separate charge — treated as naturally bundled with the principal supply of the ring, no separate line. Total invoice value: ₹142,099 with ₹2,032 of GST split across four tax-rate rows on a single bill.

The same pattern repeats across every mid-market and premium jewellery retailer in India — Kalyan Jewellers, Malabar Gold & Diamonds, Senco Gold, Joyalukkas, Reliance Jewels, and the regional and family-run stores that dominate tier-2 and tier-3 markets. What varies is store-system maturity. A well-configured ERP at a national chain generates the five-line invoice automatically from the HSN-tagged item master. A store on an older billing package may issue a two-line invoice that folds making charges into the gold value at a blended 3% — technically incorrect, but common enough to be the single largest reconciliation exposure in the category.

The Notification 11/2017-CTR overlay — why making charges are not gold

The most consequential classification decision in jewellery finance is that making charges are not part of the gold value. They are a service — specifically, job-work in relation to the manufacture of articles of jewellery falling under HSN 7113. Entry 26 of Notification 11/2017-Central Tax (Rate), as amended, taxes this service at 5% CGST + SGST combined. The service classification stands whether the karigar bills the retailer directly (in which case the retailer takes ITC on the 5% and passes the charge through to the customer at 5%) or the retailer bills the making charge directly to the customer as a labour component of the finished piece (in which case the retailer collects 5% as output tax on the making-charges line).

The classification matters because if the making charge were treated as part of the gold value, the whole invoice would be at 3%, and the retailer would under-collect 2% on that portion of the invoice value. On a national chain doing ₹4,180 crore of consolidated quarterly turnover with a blended 12% making-charge portion, the delta is roughly ₹500 crore of making-charge value at 2% delta — ₹10 crore per quarter of unrecognised GST liability that surfaces on the first Section 74 assessment or the first departmental audit. The five-year statute of limitation under Section 74 means the exposure compounds — a retailer running the wrong classification since GST inception in July 2017 faces a nine-year cumulative liability by 2026-27, before interest and penalty.

The reconciliation control that catches this is straightforward but discipline-heavy. Every invoice must have at least one HSN 7113 line at 3% and at least one SAC 9988 line at 5% whenever making charges apply. The store system flags invoices that have HSN 7113 but no SAC 9988 as exceptions for controller review, and the GSTR-1 filing engine cross-checks the ratio of SAC 9988 value to HSN 7113 value against a category norm (typically 8% to 18% depending on collection and craftsmanship tier). Ratios outside tolerance route to finance for manual verification before the return is filed.

The Section 393(1) Sl. 4 overlay — karigar TDS on the labour side

The karigar workshop that supplies making labour to the retailer is a separate reconciliation surface. When the retailer pays the karigar for labour — whether the karigar is an individual, an HUF, or a proprietary workshop — the payment falls under Section 393(1) Sl. 4 of the Income-tax Act 2025, the successor to legacy Section 194C. The applicable payment codes in the new TRACES taxonomy are 1001 (individual / HUF karigar, 1% TDS) and 1023 (other job-workers including partnership firms, 2% TDS). The threshold per deductee per financial year governs whether deduction applies, and the retailer reconciles the credit per karigar PAN in Form 26AS. The reconciliation runs alongside the GST 5% on the same making-charge flow — the karigar bills the retailer at (labour amount) + 5% GST, the retailer takes ITC on the 5% GST, deducts TDS at 1% or 2% on the labour amount (before or after GST depending on the CBDT position), and reports both the ITC and the TDS at the karigar’s PAN and GSTIN.

The classification wrinkle is that Section 393(1) Sl. 8 (legacy Section 194Q) at 0.1% applies to purchase of goods from a seller when the buyer’s aggregate turnover exceeds ₹10 crore in the preceding FY and the value of goods purchased from the seller in the current FY exceeds ₹50 lakh. A karigar who is billing pure labour is out of scope for Sl. 8 — the labour billing is a service, not goods. But a karigar who is billing goods (finished jewellery on principal-to-principal basis) crosses into Sl. 8 territory. Retailers must classify each karigar relationship at onboarding — labour job-work (Sl. 4) versus principal-to-principal supply (Sl. 8) — because mis-classification triggers the wrong TDS section, the wrong GST treatment, and the wrong ITC eligibility. See the job-work versus 194Q classification article for the full test.

A worked example — a national jewellery chain diamond-studded gold ring invoice

A national jewellery chain (illustrative — modelled loosely on the retail invoice format used by Tanishq, Kalyan Jewellers, and Malabar Gold & Diamonds) issues an invoice for a 22-carat diamond-studded gold ring in the wedding collection. The invoice consideration is ₹4.2 lakh, roughly the mid-point of the wedding-ring price band at metros in the mid-2026 gold-rate environment.

Illustrative — public disclosures do not reveal individual store invoice detail; the figures below are representative of the operating pattern, not actual retailer data. Cross-verify against your own POS export or GSTR-1 tax-rate row before action.

The invoice breaks down as follows.

LineHSN/SACDescriptionValue (₹)RateGST (₹)Line total (₹)
1711322ct gold setting, 18.4g at ₹7,220/g132,8483%3,985136,833

Presentation box (naturally bundled, no separate line)000
Invoice total393,5705,461399,031

The customer pays ₹3,99,031 against a rounded consideration of ₹4,00,000, with the remaining ₹969 either treated as a rounding-off discount (Section 15(3) compliant if the discount is recorded on the invoice) or an under-recovery captured as a store-level exception.

The GSTR-1 tax-rate row aggregation for this single invoice reads:

  • 3% row: taxable value ₹1,32,848 · CGST ₹1,993 · SGST ₹1,993
  • 5% row: taxable value ₹15,942 · CGST ₹398 · SGST ₹398
  • 0.25% row: taxable value ₹2,44,400 · CGST ₹305 · SGST ₹305 (aggregate of centre + side stones)
  • 18% row: taxable value ₹380 · CGST ₹34 · SGST ₹34

Now scale this to a store doing 40 wedding-ring invoices a day across 411 stores, 25 selling days a month — roughly 410,000 invoices a month at an average consideration of ₹1.05 lakh, or approximately ₹4,300 crore of monthly invoice value. The GSTR-1 tax-rate row for the network’s monthly filing must aggregate ~2 million individual line items into four tax-rate rows, and every line must reconcile back to a store-level POS invoice for the audit trail. The GL revenue recognition splits into four HSN codes (7113, 7102, 9988, 7326-and-similar) and reconciles to the trial balance revenue line by HSN. ITC on the 18% inputs — safety plates, presentation boxes, dies used only for specific pieces — flows into the electronic credit ledger and accumulates against the 3% output supply as inverted-duty structure, generating a Section 54(3) refund claim under Rule 89(5).

Three reconciliation findings surface from the network-level monthly run. First, 27 stores in tier-2 markets are filing invoices with HSN 7113 but no SAC 9988 line — making charges are being folded into gold value at a blended 3%, and the correction pushes ₹47 lakh of GST liability into the monthly filing. Second, the diamond value on 143 invoices was classified at HSN 7113 (3%) instead of HSN 7102 (0.25%) — the retailer over-collected ₹52 lakh of GST from customers on the delta, and the correction requires customer-facing credit notes under Section 34 within the November-following-FY window plus a GSTR-1 amendment. Third, the inverted-duty refund working under Rule 89(5) recovers ₹1.42 crore of unutilised ITC for the quarter after applying the (Turnover of inverted-rated supply × Net ITC ÷ Adjusted total turnover) − Tax payable formula. The GSTR-2B reconciliation discipline that surfaces the ITC availability is the precondition for the refund working being defensible.

Common reconciliation breakages

  • Making charges folded into gold value at 3%. The single largest under-collection pattern — invoices show HSN 7113 gold value only, no SAC 9988 making-charges line, whole invoice at 3%. The 2% delta on 8-15% of invoice value accumulates as unrecognised GST liability every filing cycle.

  • Diamond value mis-classified as HSN 7113 at 3%. Common at stores where the POS item master does not carry HSN 7102/7103 as a separate rate class. Retailer over-collects 2.75% from the customer on the centre-stone value; correction requires Section 34 credit notes and GSTR-1 amendment within the Section 34 window.

  • Presentation box mis-classified as mixed supply at 18% on the whole bundle. Stores that treat a naturally-bundled velvet box as an independent supply escalate the whole invoice to 18% under Section 8(b), massively over-collecting from the customer and mis-filing GSTR-1.

  • Inverted-duty refund calculation excluding making-charge output. Retailers who compute Rule 89(5) refund treating only 3% jewellery output as inverted-rated supply understate the refund. The 5% making-charge supply is also below the 18% input rate on packaging and dies, and the Rule 89(5) turnover-of-inverted-rated-supply denominator should reflect both.

  • Karigar TDS deducted on the GST-inclusive amount instead of the labour value. CBDT circular guidance and case law treat the labour value (pre-GST) as the deduction base under Section 393(1) Sl. 4. Retailers who deduct on the GST-inclusive amount over-deduct by the CGST + SGST portion and the karigar takes the extra credit in Form 26AS — but the retailer’s Form 27EQ / TDS return mis-states the deduction base.

How a reconciliation platform handles this

Terra Insight’s reconciliation platform (TransactIG) treats every jewellery invoice as a multi-line source event and applies a rate-classifier stage that assigns each line to its HSN- or SAC-anchored rate class before aggregation. The multi-pass matching engine cross-references the invoice-level extract against the GSTR-1 tax-rate rows, the GL revenue by HSN, the karigar labour bills for the same reference period, the ITC availability from GSTR-2B, and the Section 54(3) inverted-duty refund working — surfacing exception invoices at store level for controller review before the return is filed. Retailers running the platform typically move from 51% first-pass match to 88% first-pass match on the invoice-to-GSTR-1 reconciliation, with the residual routed to audit workflow rather than to a Section 74 exposure at year-end. The commercial pillar for the category is jewellery reconciliation software India, and the broader reconciliation software India hub anchors the cross-category architecture.

For retailers integrating the mixed-rate invoice discipline with karigar labour reconciliation, the karigar workshop labour TDS article covers the Section 393(1) Sl. 4 mechanics; for old-gold exchange interaction, see the old-gold exchange reconciliation article; and for the gold-rate fixation flow that decides invoice-level metal value on the delivery day, the metal loan gold-price fixation article walks the delivery-day-versus-invoice-day reconciliation. The purchase of goods TDS at code 1031 article covers the Section 393(1) Sl. 8 overlay for retailers buying finished jewellery on principal-to-principal basis, and the distributor commission code 1015 article covers the commission side of consignment retail models. For the GST-side interactions, ITC reversal under Rule 42 and Rule 43 frames the common-input allocation between taxable and exempt supplies, and Section 15(2) trade-discount valuation frames the discount-treatment approach that also applies to old-gold exchange consideration.

The five FAQs below address the operational questions Indian jewellery retailers ask most often when implementing structured mixed-rate invoice reconciliation.

  • Section 15, Central Goods and Services Tax Act 2017 — Value of supply. Where a single invoice carries multiple rates on distinct goods and services, the taxable value must be split line by line at the HSN or SAC level; a composite or naturally-bundled supply is taxed at the rate of the principal supply, but a mixed supply of independently sellable items is taxed at the highest rate applicable — the classification determines whether the retailer bills 3%, 5%, or 18% on the ancillary line.

Frequently Asked Questions

Why does a single Indian jewellery invoice carry three different GST rates at the same time?
Because the underlying supplies are legally distinct and the CGST valuation framework requires each to be taxed at its own rate. The gold or silver metal itself is an article of jewellery under HSN 7113 (Notification 1/2017-CTR Schedule V) and attracts 3% GST. Making charges — the labour billed by the karigar and passed through to the customer — are treated as job-work in relation to jewellery manufacture under Notification 11/2017-CTR Entry 26 at 5% GST. Ancillary items on the bill such as the presentation box, a die used only for that piece, a safety plate, or a security clasp fall into general HSN codes (7326, 4819, and similar) and attract 18% GST. The invoice must show each line at its own rate because Section 15 read with the tax-rate rules does not permit a blended rate on a mixed supply of independently sellable items — the retailer either issues three tax-rate lines or, in the composite case where the box is genuinely bundled and free, treats the box as a naturally-bundled input to the 3% principal supply. Retailers who blend rates informally invite a Section 74 GST notice at year-end.
Is a diamond-studded gold ring taxed at 3% on the whole invoice, or must diamond be split at 0.25%?
The diamond portion must be split. Diamonds and precious/semi-precious stones fall under HSN 7102 and 7103 in Schedule VI of Notification 1/2017-CTR at 0.25% GST. The gold setting and the finished jewellery classification fall under HSN 7113 in Schedule V at 3%. When the ring is billed to the customer, the invoice line for diamond value (the certified centre stone plus any side stones) is taxed at 0.25%, the gold value is taxed at 3%, and the making charge is taxed at 5%. Retailers routinely simplify to a blended 3% + 5% invoice for customer-facing readability, but the GSTR-1 filing must still split the diamond value into the 0.25% tax-rate row at the HSN 7102 or 7103 aggregate. The reconciliation between the customer invoice and the GSTR-1 filing is where the classification discipline is tested — a mis-classified diamond line inflates output tax by the delta between 3% and 0.25% multiplied by the certified stone value, and the retailer over-pays on a supply the customer has already been billed for.
How does inverted-duty structure hit a jewellery retailer's ITC balance?
Retailers buy inputs — presentation boxes, dies, security tags, safety plates, showroom fittings, packaging film, cleaning chemicals, and hallmarking services — that mostly sit at 18% GST. The output supply of finished jewellery is at 3% (plus 5% on making). The output tax collected on a typical invoice is therefore much smaller in percentage terms than the input tax paid, and ITC accumulates on the electronic credit ledger faster than it can be utilised against the 3% output. This is the inverted-duty structure defined in Section 54(3) of the CGST Act. Retailers can claim a refund of the unutilised ITC under the Rule 89(5) formula — Maximum Refund = (Turnover of inverted-rated supply × Net ITC ÷ Adjusted total turnover) − Tax payable on inverted-rated supply. In practice, the refund cycle runs six to nine months from application, and the accumulated ITC ties up working capital. The reconciliation discipline that matters is a per-invoice split between ITC attributable to 3% output supply (refundable), 5% output supply (partial), and 18% output supply on ancillary items (fully utilisable), so that the refund claim is defensible under audit.
What is the difference between a composite supply and a mixed supply on a jewellery invoice?
Composite supply under Section 2(30) of the CGST Act is a supply of two or more goods or services that are naturally bundled and supplied in conjunction in the ordinary course of business, with one being the principal supply. A gold necklace sold with a velvet presentation box included at no separate charge is a composite supply — the necklace is the principal supply at 3%, the box is naturally bundled, and the whole invoice is taxed at 3%. Mixed supply under Section 2(74) is two or more independent supplies made for a single consolidated price that are not naturally bundled. A jewellery gift hamper containing a gold coin, a silver idol, a chocolate box, and a designer diary sold at a single price is a mixed supply — Section 8(b) requires the entire bundle to be taxed at the highest single rate applicable, which in this hamper would be 18% on the whole hamper value. Retailers who bill genuinely bundled boxes as separate 18% lines over-collect GST from the customer; retailers who bundle independently sellable items into a composite framing under-collect. The invoice-level determination of composite versus mixed drives the entire reconciliation.
How does old-gold exchange interact with the mixed-rate invoice reconciliation?
Old-gold exchange creates a second supply on the same invoice — the customer supplies gold to the retailer (a sale of gold by the customer to the retailer) and the retailer supplies new jewellery. Where the customer is unregistered, no GST is chargeable on the customer's leg because an unregistered person's supply is out of scope; the retailer treats the exchange value as a discount on the new-jewellery leg under Section 15(3) and issues a tax invoice for the net consideration. Where the customer is registered (rare in retail, common in B2B refining flows), the customer's leg is a taxable supply at 3% on the gold value and generates a purchase invoice for the retailer, which lands in GSTR-2B as inward supply. The reconciliation must separate the exchange discount treatment from the outright sale treatment because the two flow through GSTR-1 and GSTR-2B differently. See the [old-gold exchange reconciliation article](/insights/old-gold-exchange-new-purchase-reconciliation-section-194ia-india/) for the full sequence with worked numbers.
