Problem

Indian auto-component manufacturers undertaking greenfield or brownfield capex face a line-by-line ITC eligibility decision under Section 16(1) of the CGST Act, Section 17(5) blocks, Rule 43 spreading where output is partly exempt or zero-rated, the EPCG scheme override for export-tied imported capex, and Section 18(6) accelerated reversal on mid-life disposal. A ₹18 crore greenfield press shop typically carries 60 to 90 capex line items spanning press lines, CNC machining, robotic cells, paint booths, ETP, ASRS, IoT sensors, MEP infrastructure, civil works and office equipment — each line with a different ITC story. Mis-classifying even a small number of lines at capitalisation creates ₹15 to ₹40 lakh of audit-findable exposure that surfaces at GSTR-9 reconciliation, and the structural Rule 43 reversal on the 10% to 15% export share creates a recurring ITC leakage that compounds over the 60-month attribution window.

How It's Resolved

Build a line-by-line capex ITC eligibility matrix at the procurement stage; classify each line as (a) Section 16 eligible plant and machinery, (b) Section 17(5) blocked, (c) partly blocked under Section 17(5)(c) for civil-works-adjacent infrastructure, (d) EPCG-imported with refund-versus-utilise decision, or (e) shared-use with Rule 43 attribution; for each eligible line, stamp the capitalisation date, ITC amount, 60-month schedule and Rule 43 monthly attribution; run the monthly Rule 43 reversal automatically against the live exempt-turnover ratio; on disposal, compute the Section 18(6) reversal; reconcile to capital-goods register at GSTR-9 Tables 6C and 7.

Configuration

Capex line-item master with Section 16/17(5) classification, EPCG status flag, shared-use status, Rule 43 schedule, monthly attribution and reversal; live exempt-turnover ratio feed from sales register; refund-versus-utilise decision workflow for EPCG-imported assets; disposal workflow with Section 18(6) computation; reconciliation rule between capex line-item master, GSTR-3B Tables 4 and GSTR-9 Tables 6 and 7.

Output

A line-by-line capex ITC eligibility decision register; a monthly Rule 43 attribution and reversal schedule across all capitalised assets; a refund-versus-utilise position for EPCG-imported capex; a disposal-side Section 18(6) reversal queue; and a GSTR-9 audit-defence pack tying every capex line to Section 16, 17(5) or Rule 43.

A Tier-1 forging and machining supplier in Pithampur opens the GST review on its ₹18 crore greenfield press shop on 1 May 2025 at 10:00 IST. The plant capitalisation register lists 73 line items procured between September 2024 and April 2025 — two 800-tonne mechanical press lines (₹4.8 crore each), three CNC machining cells (₹1.4 crore each), one robotic deburring cell (₹2.2 crore), one paint booth (₹1.6 crore), one ETP plant (₹0.9 crore), one ASRS rack system (₹1.1 crore), 84 IoT condition-monitoring sensors (₹0.32 crore aggregate), MEP infrastructure (₹0.85 crore), civil works (₹1.4 crore), office fitments (₹0.18 crore), forklift trolleys (₹0.42 crore) and a tail of small items. Aggregate spend ₹18.2 crore. Aggregate GST paid ₹3.28 crore. The CFO has two questions on the desk. Of the ₹3.28 crore of GST paid, how much is actually ITC-eligible, and what is the structural Rule 43 reversal exposure given that 12% of the plant’s projected output will go to a SEZ customer under LUT. ITC capital goods auto manufacturing India is a line-by-line decision, not an aggregate decision, and the line decisions decide whether ₹3.28 crore matures into ₹2.7 to ₹2.9 crore of net retained ITC or drops materially lower.

The line-by-line classification matrix

For the Pithampur greenfield press shop, the ITC classification across the 73 line items resolves into five buckets:

Bucket 1 — Section 16 eligible plant and machinery (clean). Press lines, CNC cells, robotic cell, paint booth (machinery portion only), ETP plant (machinery portion), ASRS rack system, IoT sensors, MEP electrical (transformers, panels, machinery feeders). These are the core production assets and the eligibility is direct. ITC = full GST paid on these lines, Rule 43 spreading applies to the extent of any exempt or zero-rated turnover share.

Bucket 2 — Section 17(5)(a) potentially blocked. Motor vehicles with seating capacity up to 13 persons. The Pithampur plant has procured one Tata Ace tempo for inbound material movement — this is a motor vehicle and the ITC is blocked unless used for further taxable supply (it is not; it is for own internal use). Block applies. Forklifts: these are off-road equipment, not motor vehicles for Section 17(5) purposes, and ITC is eligible. The distinction is the motor-vehicle registration — if it carries an RTO registration plate it is a motor vehicle; if it operates on internal company plates as a forklift it is industrial equipment.

Bucket 3 — Section 17(5)(c) civil-works boundary. The most-litigated boundary. The 17(5)(c) block carves out plant and machinery from the civil-works block, but where does plant-and-machinery end and structural civil works begin. The post-2017 jurisprudence has settled on the following operational lines for auto-manufacturing facilities: foundations and supporting structures for production machinery are plant and machinery (ITC eligible); load-bearing sheds and roofs covering the shop floor are civil works (ITC blocked); paint-booth ducting integral to the booth is plant and machinery; building HVAC for office areas is civil works; ASRS structural racking is plant and machinery; office buildings, canteens and toilets are civil works. For the Pithampur ₹1.4 crore civil-works line, classification splits roughly 35% to plant-and-machinery foundations (eligible) and 65% to load-bearing shed and office building (blocked).

Bucket 4 — EPCG-imported with refund-versus-utilise. Two of the three CNC machining cells were imported under EPCG authorisation. IGST at import was paid in cash (₹46 lakh aggregate). The ITC is available against this payment. The plant’s projected export obligation under EPCG is six times the duty saved (₹2.76 crore of export over 6 years). The plant’s actual projected SEZ export over 6 years is roughly ₹1.6 crore (12% share). The supplier will need to meet the residual ₹1.16 crore export obligation either by extending the export share over the 6 years or by alternative-route compliance (deemed export to EOU customers). The ITC on the IGST paid in cash remains fully eligible and lands in the capital-goods register on a Rule 43 60-month schedule.

Bucket 5 — Personal-consumption blocked. Office fitments to the extent they relate to staff hospitality areas (canteen tables, water-dispensers): Section 17(5)(g) block. To the extent they relate to operational areas (engineering workstations, production-office desks): eligible.

The classification aggregate for the Pithampur press shop:

Bucket 1 — clean eligible: ₹14.1 crore of capex, ₹2.54 crore of ITC.
Bucket 2 — motor vehicle block: ₹0.06 crore of capex on the Tata Ace, ₹0.011 crore of ITC blocked.
Bucket 3 — civil-works split: ₹0.49 crore of plant-and-machinery foundations eligible (₹0.088 crore of ITC), ₹0.91 crore of structural civil-works blocked (₹0.164 crore of ITC blocked).
Bucket 4 — EPCG IGST: ₹2.55 crore of capex with ₹0.46 crore of IGST in cash; ITC eligible on the ₹0.46 crore.
Bucket 5 — office fitments split: ₹0.10 crore eligible, ₹0.08 crore blocked (₹0.014 crore ITC blocked).

Aggregate ITC eligible: ₹3.10 crore. Aggregate ITC blocked at procurement: ₹0.19 crore. Block ratio on capex: 5.7%.

The Rule 43 reversal mechanic on the eligible capex

Once the line-by-line eligibility is settled, the Rule 43 mechanic spreads the eligible ITC over 60 months from the capitalisation date and proportionately reverses the share attributable to exempt or zero-rated supplies.

For the Pithampur press shop with ₹3.10 crore of eligible ITC:

Aggregate monthly Rule 43 attribution: ₹3.10 crore divided by 60 = ₹5.16 lakh per month for the next 60 months (assuming all 73 lines capitalised in approximately the same month, which is approximately true for a greenfield commissioning).
Projected exempt-turnover ratio: 12% — derived from the SEZ-customer share of projected output. SEZ exports under LUT are zero-rated supplies, which are treated as exempt for Rule 43 reversal purposes (they have no output tax against which to set off the input credit).
Monthly Rule 43 reversal under Table 4(B)(1) of GSTR-3B: ₹5.16 lakh times 12% = ₹62,000 per month.
Annual Rule 43 reversal: ₹7.44 lakh.
Cumulative reversal over 60 months: ₹37.2 lakh.

Net retained ITC over 60 months: ₹3.10 crore minus ₹0.37 crore = ₹2.73 crore.

Net-net: of the ₹3.28 crore of GST originally paid on the ₹18.2 crore capex, the supplier retains ₹2.73 crore of usable ITC after Section 17(5) blocks (₹0.19 crore) and Rule 43 reversals (₹0.37 crore). The capex ITC efficiency is 83% — a reasonable benchmark for a greenfield press shop with a 12% export share.

Where the audit-time exposure typically lands

Five patterns dominate at GSTR-9 reconciliation and capital-goods audit:

1. Civil-works boundary mis-classified. The plant’s project finance team capitalises the full ₹1.4 crore of civil works as eligible plant-and-machinery; the audit applies the Section 17(5)(c) carve-out and reverses the structural civil-works share. Audit finding ₹15 to ₹30 lakh range on a typical greenfield commissioning.

2. Motor-vehicle classification confusion on forklifts and trolleys. If a forklift has been registered on RTO plates (some plants do this for parking-area movement to an external warehouse), the Section 17(5)(a) block applies. Most plants run forklifts on internal company plates and the issue does not arise, but audit will check.

3. EPCG-IGST not separately tracked. The IGST paid in cash on EPCG-imported capital goods is fully eligible ITC, but the EPCG authorisation creates a parallel export-obligation tracking that the supplier has to run for 6 years. Audit cross-references the export performance against the EPCG closure file.

4. Rule 43 reversal not run monthly. The most common operational lapse. The monthly one-sixtieth reversal is computed but the exempt-turnover ratio is applied annually rather than monthly. Audit re-computes on monthly turnover and surfaces the variance.

5. Section 18(6) on disposal missed. A CNC machine sold mid-life carries an output-tax invoice but no Section 18(6) accelerated reversal. Audit picks up the gap between the higher of unamortised-ITC and disposal-tax, and applies the higher amount.

Worked example — the ₹18 crore greenfield press shop, 60-month forward view

The Pithampur supplier’s 60-month forward view on its capex ITC:

Aggregate eligible ITC available at capitalisation: ₹3.10 crore.
Aggregate ITC blocked at procurement: ₹0.19 crore.
Net retainable over 60 months at 12% SEZ share: ₹2.73 crore.
Monthly cash-equivalent ITC benefit: ₹2.73 crore divided by 60 = ₹4.55 lakh per month of GST liability that the press shop’s output covers internally without cash outflow.
Year 1 Rule 43 reversal cash impact: ₹7.44 lakh (or 4.5% of full annual ITC).
EPCG export obligation tracking: ₹2.76 crore over 6 years against actual projected SEZ of ₹1.6 crore. Gap to close ₹1.16 crore over 6 years — typically closed through (a) increased SEZ share, (b) deemed exports to EOU customers, or (c) EPCG authorisation extension.

The supplier’s CFO commits to two operating disciplines after the review. First, a monthly Rule 43 reversal run synced to the live exempt-turnover ratio from the sales register (not an annual averaging). Second, an EPCG export-performance dashboard that tracks the cumulative export obligation versus the cumulative actual export, with alerts at the 60th, 70th and 80th percentile of the closure window.

Tax overlay — TDS on capex procurement

The capex GST workflow is the indirect-tax leg. The TDS leg under the Income Tax Act 2025:

Section 393(1)(k), payment code 1012 — TDS by the buyer at 0.1% on aggregate purchases above ₹50 lakh per FY from any single seller. For a ₹18.2 crore capex spread across 28 vendors with the largest single-vendor spend at ₹4.8 crore (the press line OEM) and the smallest at ₹0.18 crore (a small civil-works contractor), most vendors will cross the ₹50 lakh threshold and 0.1% TDS applies on every payment.
EPCG-imported capex: TDS does not apply to overseas vendors directly (Indian Section 393 does not reach overseas suppliers); the import-duty and IGST framework governs at the port of entry.
GST law is unchanged by the Income Tax Act 2025. Section 16, Section 17(5), Rule 43 and Section 18(6) all continue as before. Only the TDS overlay carries the new payment-code stack from 1 April 2026. Cross-era in TDS payment codes 1001-1092.

How does capital-goods ITC interact with GSTR-9?

Three things must tie at year-end:

GSTR-3B Table 4 — monthly Rule 43 attribution under Table 4(A)(5) and monthly reversal under Table 4(B)(1).
GSTR-9 Table 6C and Table 7D — Table 6C cumulative capital-goods ITC for the year; Table 7D cumulative Rule 43 reversals.
Capital-goods register — every capex line with eligibility classification, 60-month schedule, cumulative attribution and reversal.

Frequently Asked Questions

What is the basic eligibility rule for capital-goods ITC under Section 16(1)?

Section 16(1) of the CGST Act says that every registered person, subject to the conditions and restrictions, is entitled to take Input Tax Credit on the supply of goods or services or both which are used or intended to be used in the course or furtherance of business. For capital goods this translates into a 100% credit eligibility at the time of receipt of the asset, subject to four conditions in Section 16(2): possession of the tax invoice, receipt of the goods, payment of tax to the government by the supplier, and filing of GSTR-3B by the recipient claiming the credit. Capital goods specifically must also satisfy the Section 2(19) definition — capitalised in the books of the recipient and used in the course of business. Where the capital goods are used partly for taxable supplies and partly for exempt or zero-rated supplies, Rule 43 spreads the credit over a 60-month useful-life window with proportionate reversals.

Which Section 17(5) blocks apply to common auto-component capex?

Section 17(5) lists categories where ITC is blocked notwithstanding the general eligibility under Section 16. The relevant blocks for auto-manufacturing capex are: (a) motor vehicles and other conveyances with seating capacity up to 13 persons, except where used for further taxable supply, transportation of passengers or for training — this blocks forklifts only if classified as motor vehicles, but most industrial forklifts and trolleys are off-road equipment and ITC-eligible; (c) construction of immovable property except plant and machinery — this blocks civil-works ITC for sheds, offices, drains, except where the structure is plant and machinery (the boundary line is the most-litigated single capex issue); (d) goods or services received for personal consumption — blocks staff hospitality and employee-amenity ITC; (h) goods lost, stolen, destroyed, written off or disposed by way of free samples — blocks ITC on scrapped capital goods to the extent of unamortised remaining-useful-life. For a typical greenfield press shop the Section 17(5) blocks usually account for 2% to 6% of total capex ITC.

How does Rule 43 of the CGST Rules actually spread the capital-goods ITC?

Rule 43 of the CGST Rules covers the apportionment of capital-goods ITC where the registered person makes both taxable and exempt (or zero-rated under LUT) supplies. The mechanic: total ITC available on the capex is divided by 60 to produce a monthly attribution; the monthly attribution is multiplied by the exempt-to-total turnover ratio for that month under Rule 43(1)(e); the resulting figure is reversed in Table 4(B)(1) of the GSTR-3B for that month. Where the registered person makes 100% taxable supplies, the reversal under Rule 43(1)(e) is zero and the full credit matures cleanly over 60 months. Where the registered person makes 100% exempt or zero-rated supplies, the reversal equals the monthly attribution and no credit is retained. For a typical Tier-1 with a 90% domestic taxable, 10% SEZ-export mix, the cumulative reversal over 60 months equals 10% of the original ITC. The full Rule 43 mechanic on tooling is in [GST on auto-component tooling under Rule 43](/insights/gst-tooling-capital-goods-rule-43-auto-component-india/).

How does the EPCG scheme interact with capital-goods ITC?

The Export Promotion Capital Goods (EPCG) scheme under the Foreign Trade Policy allows zero-duty import of capital goods against an export obligation typically equal to six times the duty saved, to be fulfilled within 6 years from the EPCG authorisation date. When a CNC machine or robotic cell is imported under EPCG, the basic customs duty is zero but IGST on import is payable in cash — the supplier cannot use ITC to pay it because of the EPCG authorisation conditions. Once the IGST is paid in cash at the port of import, the supplier becomes eligible to take ITC on it as capital-goods ITC under Rule 43. The wrinkle: where the EPCG authorisation requires a minimum export ratio that does not match the supplier's actual export-versus-domestic split, the supplier may be forced into a refund-versus-utilise decision — either utilise the ITC against domestic output and meet the export obligation through alternative routes, or claim a refund of the IGST under the inverted-duty-structure provisions where applicable.

What happens to capital-goods ITC if the asset is scrapped or sold before the 60 months are up?

Section 18(6) of the CGST Act and Rule 44(6) of the CGST Rules trigger an accelerated reversal on disposal of capital goods. The amount payable equals the higher of (a) the ITC that remains unamortised on the remaining-useful-life proportion (computed as total ITC times remaining-months divided by 60) or (b) the tax on the actual transaction value of the disposal. If a CNC machine procured for ₹2.4 crore with ₹43.2 lakh of ITC is scrapped at month 38, the remaining unamortised ITC is ₹43.2 lakh times 22 divided by 60 = ₹15.84 lakh. If the scrap sale value is ₹45 lakh and GST at 18% is ₹8.1 lakh, the reversal payable is the higher = ₹15.84 lakh. The reversal lands in the GSTR-3B of the disposal month under Table 4(B)(2). Section 17(5)(h) also independently blocks ITC on capital goods written off — if the machine is junked without a sale (no consideration), the Section 18(6) mechanic still applies on the unamortised remaining-useful-life basis.
