An Indian EV motor controller Tier-1 supplier to OEMs like Ather Energy operates inside two regulatory frameworks (PLI-Auto Component for the supplier, PLI-Auto Champion for the OEM) and three commercial structures (hardware sale, firmware licence, calibration/OTA subscription) on the same SKU. Holding 50 percent component-level DVA evidence per batch, three-PO Ind AS 115 transaction-price allocation, base-year incremental-sales calculation against PMA-IFCI methodology, and Section 393 code 1012 TDS reconciliation against Form 26AS each quarter requires a single auditable thread tying each motor-controller unit sold to its underlying bill-of-materials and domestic-vs-imported content.
Maintain a motor-controller SKU bill-of-materials master with each line tagged domestic or imported referenced to supplier GSTIN invoice or Bill of Entry. Compute per-batch DVA as (sale value minus imported-content landed cost) divided by sale value; aggregate quarterly for PLI-Auto Component claim. Split each unit sale across three Ind AS 115 performance obligations (hardware, firmware, calibration/OTA) at stand-alone selling prices; recognise hardware and firmware on control transfer and calibration/OTA over service period. Build base-year incremental-sales calculation against PMA-IFCI methodology with quarterly claim file. Reconcile Section 393 code 1012 (legacy 194Q) TDS at 0.1 percent deducted by OEM buyer against Form 26AS by deductor TAN by quarter.
Motor-controller SKU master with three-component sale structure and stand-alone selling prices; bill-of-materials master with each line domestic-or-imported flagged and supplier/BoE reference; supplier master with domestic GSTIN; Bill-of-Entry register with CIF, duty, clearance and MOOWR/EPCG refund status; PLI-Auto Component registration with base-year sales and incremental-sales calculator; FAME-II content-test report template feeding OEM DVA submission; Section 393 code 1012 TDS receivable ledger; Form 26AS quarterly reconciliation by OEM TAN.
A per-batch DVA reconciliation pack with domestic-vs-imported bill-of-materials evidence; Ind AS 115 three-PO revenue recognition with deferred-revenue ageing for calibration/OTA subscription; quarterly PLI-Auto Component claim file in PMA-IFCI prescribed format with incremental-sales calculation against base-year; OEM content-test report feeding vehicle-level DVA submission; Section 393 code 1012 TDS reconciliation against Form 26AS with chase-list for missing credits; clawback-resistant audit trail per unit sold.
A Pune-based motor-controller Tier-1 closes Q1 FY 2026-27 with 92,000 controllers dispatched to Ather Energy’s Hosur plant — 58,000 units for the 450X variant, 24,000 for the 450S and 10,000 for the new Rizta family-scooter platform. Each controller carries three commercial components (hardware, firmware licence, calibration/OTA subscription) and feeds two PLI-Auto streams (Component at supplier, Champion at OEM). The EV motor controller supplier reconciliation PLI-Auto India discipline ties one quarterly sale book of approximately ₹46 Cr to a defensible 50 percent component-level DVA, a three-PO Ind AS 115 allocation, a base-year incremental-sales calculation and a Section 393 code 1012 TDS chase against the OEM’s Form 26AS filing.

What is the PLI-Auto Champion scheme and how does it apply to motor controllers?
The Production Linked Incentive scheme for the Automotive Sector and Auto Components (PLI-Auto) was notified by the Ministry of Heavy Industries in 2021 with two streams:
- Champion OEM — incentive paid to vehicle OEMs producing Advanced Automotive Technology (AAT) vehicles, where the OEM commits a capacity-linked capital expenditure and hits both vehicle-level DVA and committed-sales milestones.
- Component — incentive paid to component manufacturers of AAT components and sub-assemblies, including motor controller (inverter + ECU), traction motor, BMS, e-axle, electric powertrain components, fuel cell sub-assemblies, on-board sensors and ADAS components.
Motor controllers qualify under the AAT component category if they meet the technology specification (typically vector-control inverter with regen-braking, ECU with model-specific torque vectoring) and the 50 percent component-level DVA threshold.
A motor-controller supplier can also indirectly support its OEM customer’s Champion-stream claim, because the OEM’s vehicle-level DVA is built up from component-level DVA evidence. The supplier’s content-test report feeds into the OEM’s claim file even where the supplier is itself claiming under the Component stream separately.
How is the 50 percent component-level DVA computed?
Component-level DVA:
DVA percent = (Component Sale Value minus Imported Content Landed Cost) divided by Component Sale Value
Imported content is determined at landed cost — CIF value plus customs duty plus clearance, net of MOOWR or EPCG refund where applicable. The typical imported lines in a modern motor controller:
| Item | Typical origin | Share of BoM |
|---|---|---|
| MCU (32-bit ARM Cortex-M) | NXP, ST, Infineon, Renesas | 8-12% |
| Power MOSFETs / IGBTs | Infineon, ON Semi, ROHM | 18-25% |
| Gate-driver ICs | Infineon, TI, ADI | 4-7% |
| Current sensors (Hall-effect) | Allegro, Melexis | 3-5% |
| DC-link capacitor bank | TDK, Murata (some domestic via Epcos India) | 8-12% |
| PCB substrate | Mostly domestic (Genus, AT&S India, AVL) | 6-9% (domestic) |
| Connectors / harness | Mostly domestic (TE India, Amphenol, Aptiv) | 5-8% (domestic) |
| Enclosure / heat-sink | Domestic die-cast aluminium | 8-12% (domestic) |
| SMT assembly + test (in-house value-add) | In-house | 15-20% (domestic) |
Hitting 50 percent component-level DVA requires domestic PCB substrate, domestic enclosure, domestic connectors and a meaningful in-house value-addition (SMT, test, firmware burn, end-of-line calibration). The MCU and power semiconductors will typically remain imported through Year 1-3 of the scheme.
How is a motor controller commercially structured for revenue recognition?
The standard structure is three commercial components:
| Component | Pattern | Ind AS 115 PO | Revenue recognition |
|---|---|---|---|
| Hardware (controller box) | One-time sale at vehicle production | PO 1 | At control transfer (dispatch + GRN) |
| Firmware licence | Perpetual or per-unit licence | PO 2 | At control transfer with firmware delivery |
| Calibration + OTA subscription | Recurring service over vehicle life | PO 3 | Over service period |
A motor-controller unit sold to Ather Energy at ₹5,000 ASP typical configuration might allocate as: hardware ₹4,200 (84 percent), firmware ₹450 (9 percent), 36-month calibration/OTA subscription ₹350 (7 percent recognised over 36 months at ₹9.7 per month).
Ind AS 115 step 4 transaction-price allocation requires a stand-alone-selling-price (SSP) determination for firmware and OTA. Best practice is a documented cost-plus or residual approach, reviewed annually.
How is the quarterly PLI-Auto Component claim built?
Each quarterly claim file submitted to IFCI as PMA requires:
- Sales of qualifying motor-controller SKUs — dispatch register with tax invoice, IRN, e-way bill, OEM buyer GSTIN, unit count, ASP and SKU code.
- DVA computation per batch — bill-of-materials with domestic-vs-imported tagging, domestic supplier invoices (GSTIN, value, qty) and Bill of Entry references for imported content (port, BoE number, CIF, duty, clearance, MOOWR/EPCG refund status, landed cost).
- Base-year reconciliation — cumulative incremental sales against base-year baseline, with incentive computation at the scheme’s per-year rate.
- Capacity-utilisation and capex evidence — investment commitment status and cumulative capex against committed plant capacity.
PMA processes the claim, disburses on approval and runs annual audit. Discrepancies between declared and audited DVA trigger clawback of prior disbursements.

Open the Exception Cost Calculator →Worked example — Pune Tier-1 to Ather Energy, Q1 FY 2026-27
- Controllers dispatched in Q1: 92,000 units across three OEM model codes (450X 58,000; 450S 24,000; Rizta 10,000)
- Per-unit ASP: ₹5,000 average across the mix
- Total dispatch value: ₹46 Cr
- Ind AS 115 revenue allocation:
- Hardware (84%): ₹38.64 Cr recognised on control transfer in Q1
- Firmware (9%): ₹4.14 Cr recognised on firmware delivery in Q1
- Calibration/OTA (7%): ₹3.22 Cr deferred, recognised at ₹8.94 lakh per month over 36 months
- Bill-of-materials at per-unit average ₹3,650 cost:
- Domestic content: ₹2,010 (PCB substrate, enclosure, connectors, capacitor bank from domestic supplier, in-house SMT + test + firmware burn + EoL calibration)
- Imported content (net of MOOWR refund): ₹1,640 (MCU, MOSFETs, gate drivers, current sensors)
- Component-level DVA: (₹5,000 minus ₹1,640) divided by ₹5,000 = 67 percent — comfortably above 50 percent threshold
- Base-year quarterly baseline: 60,000 units; Q1 incremental sales: 32,000 units
- PLI-Auto Component incentive (illustrative band at scheme matrix): ₹450-650 per incremental unit
- Estimated quarterly PLI claim: ₹1.44 to ₹2.08 Cr
- Backup evidence: 92,000 sale invoices with IRN, 47 domestic supplier invoices, 8 customs Bills of Entry with refund-status cross-reference, capacity-utilisation log
- Section 393(1)(k) code 1012 TDS deducted by Ather Energy at 0.1 percent on purchases above ₹50 lakh FY threshold: ₹4.6 lakh on the ₹46 Cr Q1 sale, reconciled against Form 26AS at Q1 close
What does the Section 393 / GST overlay look like?
- Section 393(1)(k) code 1012 (legacy 194Q) — Ather Energy as buyer deducts 0.1 percent TDS on motor-controller purchases above the ₹50 lakh FY threshold. The supplier sees this in Form 26AS by quarter and reconciles against per-OEM sales. See Payment Code 1012 — Section 393(1)(k) Purchase of Goods.
- GST on hardware and firmware sale — IGST/CGST+SGST at notified rate on the combined hardware+firmware revenue at control transfer. ITC on imported-content customs IGST is available, subject to GSTR-2B match.
- GST on calibration/OTA subscription — continuous supply of services under Section 13 with periodic invoicing and IGST at standard rate.
- Cross-era note — pre-1 April 2026 TDS deducted under legacy Section 194Q must be cross-referenced to the new code 1012 framework for at least one full FY cycle. See TDS payment codes 1001-1092 India.
