An ACC battery giga-factory awardee under the DHI PLI Rs 18,000 crore Advanced Chemistry Cell scheme with a committed GWh capacity (illustratively 10 GWh at a Jamnagar Gujarat giga-facility per an applicant such as Reliance New Energy Storage) must reconcile a GWh capacity commissioning milestone calendar against the Letter of Award date (T0), the T + 24 months pilot line commissioning target of typically 20 to 30 percent of committed capacity, the T + 36 to 48 months partial commercial capacity target of 50 to 70 percent, and the T + 60 months full committed capacity operational target, against actual quarter-on-quarter commissioning capex, the DHI portal capacity and DVA reporting cycle, a show-cause response register tracking every DHI inquiry on a milestone GWh shortfall, and a force-majeure claim register with contemporaneous evidence for each exceptional-circumstance defence. Missing any milestone by more than the DHI-tolerated grace window triggers a per-GWh incentive reduction unless force majeure is accepted, and the milestone-linked disbursement (illustratively Y2 pilot ~10 percent, Y3 partial ~40 percent, Y5 full ~50 percent with retention held until Y7) is bound to the certification chain. The retention hold and the Ind AS 20 conditional-grant recognition timing add a further layer to the reconciliation.
Build a GWh milestone calendar keyed to the Letter of Award date T0 with four anchor events: T + 24 months pilot (20 to 30 percent), T + 36 to 48 months partial commercial (50 to 70 percent), T + 60 months full (100 percent), and T + 84 months retention release. Ingest the quarter-on-quarter commissioning capex from the SAP FI or Oracle Fusion capex ledger, stamp each capex tranche against the plant-line commissioning trajectory (cathode active material plant, anode plant, electrolyte plant, cell assembly line, module assembly line), and reconcile the quarter-end committed-capacity delta against the milestone target curve. Maintain the DHI portal reporting workbook per quarter with the third-party inspection agency (TPIA) capacity certification, the per-GWh operational proof documents (cell samples, energy density lab reports, safety qualification test reports), and the DVA workbook per stage. Log every DHI show-cause inquiry with the date received, the specific shortfall cited, the response filed date, the force-majeure claim referenced (if any), the DHI assessment received, and the resulting disbursement adjustment. Maintain a force-majeure claim register with event date, evidence type, evidence source, GWh impact, days of slippage, and DHI acceptance status. Recognise the milestone-linked PLI grant under Ind AS 20 on each milestone certification event with the presentation choice between other income and net-of-depreciation, and treat the retention balance as a contingent receivable until the Year 7 release condition is met.
GWh milestone calendar per LoA date (T0, T + 24m, T + 36m to 48m, T + 60m, T + 84m retention release); committed-capacity target curve per milestone with 20-30% / 50-70% / 100% shape; quarter-on-quarter commissioning capex ledger by plant line (cathode active material, anode, electrolyte, cell assembly, module); actual GWh commissioning delta vs milestone target; DHI portal reporting workbook per quarter with TPIA capacity certification, energy density lab report, safety qualification test report, per-stage DVA workbook; DHI show-cause response register (date received, shortfall cited, response filed, force-majeure claim reference, DHI assessment, disbursement adjustment); force-majeure claim register (event date, evidence type, evidence source, GWh impact, days slippage, acceptance status); per-GWh indicative incentive band per applicant (illustrative Rs 400-600 cr per GWh over 5-year window); milestone-linked disbursement schedule (Y2 ~10%, Y3 ~40%, Y5 ~50% with retention); Y7 retention release condition workbook (sustained committed GWh, sustained DVA, sustained energy density, sustained safety); Ind AS 20 recognition template per milestone with presentation choice; Section 115JB MAT book-profit adjustment schedule; Section 115BAA regime flag; retention contingent-receivable sub-ledger.
A milestone-linked PLI ACC claim pack: the GWh milestone calendar reconciled against the actual quarter-on-quarter commissioning capex and committed-capacity delta at each milestone event, with per-milestone certification (TPIA capacity certification, energy density lab report, safety qualification test report) linked; the per-milestone incentive computation with the per-GWh indicative incentive band applied and the LoA ceiling binding shown explicitly; the DHI show-cause response register with every inquiry logged, response filed, DHI assessment recorded, and downstream disbursement adjustment traced; the force-majeure claim register with contemporaneous evidence per event and DHI acceptance status per claim; the quarter-on-quarter DVA workbook per plant stage; the Ind AS 20 grant receivable ledger per milestone with presentation choice; the Section 115JB MAT book-profit adjustment line per FY into the tax provisioning workflow; and the retention contingent-receivable sub-ledger with Year 7 release conditions and the operational-proof documentation across the 2-year post-commissioning window.
An ACC battery giga-factory awardee under the Department of Heavy Industries PLI Advanced Chemistry Cell Rs 18,000 crore scheme — at the scale of Reliance New Energy Storage with an illustrative 10 GWh committed capacity at the Jamnagar Gujarat giga-facility, or Ola Electric Cell Technology at 10 GWh Krishnagiri Tamil Nadu — closes each milestone window under the scheme with four reconciliation surfaces simultaneously in view: a GWh capacity commissioning milestone calendar keyed to the Letter of Award date, a quarter-on-quarter commissioning capex ledger reconciled against the milestone target curve, a DHI show-cause response register tracking every inquiry on a GWh shortfall, and a force-majeure claim register with contemporaneous evidence for each exceptional-circumstance defence. This is PLI ACC battery GWh capacity milestone reconciliation at operating scale for a giga-factory awardee, and the discipline that keeps the milestone calendar, the capex-vs-commitment tracker, the DHI portal reporting cycle, the show-cause response register, and the force-majeure claim log simultaneously clean is what separates an awardee whose Year 3 partial commercial disbursement lands on schedule from one whose disbursement is cut pro rata on a rejected force-majeure claim.
The reconciliation in one paragraph
A PLI ACC Battery awardee runs a four-surface reconciliation cascade across the 5-year milestone-linked disbursement window. Surface one is the GWh milestone calendar — anchored to the Letter of Award date T0 with four milestone events (T + 24 months pilot line at 20 to 30 percent of committed capacity, T + 36 to 48 months partial commercial at 50 to 70 percent, T + 60 months full committed capacity operational at 100 percent, and T + 84 months retention release after 2 years of post-commissioning operational proof). Surface two is the quarter-on-quarter commissioning capex ledger — capex tranches stamped against each plant line in the giga-factory (cathode active material plant, anode plant, electrolyte plant, cell assembly line, module and pack assembly line) with the actual quarter-end committed-capacity delta reconciled against the milestone target curve. Surface three is the DHI portal reporting workbook per quarter with third-party inspection agency (TPIA) capacity certification, energy density lab report, safety qualification test report per DHI-certified technology partner, and the per-stage DVA workbook running from imported cathode active material (currently 100 percent import from China and South Korea for most awardees) through domestic anode, electrolyte, separator, and can. Surface four is the DHI show-cause response register combined with the force-majeure claim register — every DHI inquiry on a GWh shortfall logged with the response filed, the force-majeure claim referenced, the DHI assessment received, and the resulting disbursement adjustment traced through the Ind AS 20 recognition entry and the Section 115JB MAT book-profit adjustment. Terra Insight’s PLI ACC Battery Rs 18,000 crore DHI claim reconciliation cornerstone sits upstream and situates the GWh milestone reconciliation within the broader DHI scheme mechanic; this article drills into the milestone-and-capex reconciliation grammar specifically.
What the scenario looks like in India — the illustrative persona
The DHI ACC Battery PLI awardee universe as at the current commissioning window is small and named — DHI has awarded approximately 50 GWh of aggregate committed capacity across the anchor beneficiaries: Reliance New Energy Storage (10 GWh committed at Jamnagar Gujarat), Ola Electric Cell Technology (10 GWh committed at Krishnagiri Tamil Nadu with commissioning ongoing FY 2025-26), Rajesh Exports Karnataka JV (5 GWh phase 1), Amara Raja Advanced Cell Technologies Andhra Pradesh (5 GWh), and Mahindra Susten JV (approximately 5 GWh). Each awardee’s Letter of Award carries a per-applicant GWh commitment, a per-GWh indicative incentive band over the 5-year window (illustratively in the Rs 400 to 600 crore per GWh range, subject to the confidential LoA terms), and a milestone-linked disbursement schedule anchored to the LoA date.
For the illustrative worked example in this article, take a giga-factory awardee at the scale of Reliance New Energy Storage running a 10 GWh commitment awarded in 2022 (T0) at the Jamnagar Gujarat integrated giga-facility. The persona is illustrative; the actual Reliance LoA capacity, per-GWh indicative incentive band, and quarter-by-quarter commissioning trajectory are governed by the confidential DHI bid outcome, and the numbers below are illustrative of the reconciliation surface, not a claim about Reliance’s specific PLI position or its actual commissioning performance. The point of the persona is the milestone-linked reconciliation surface at giga-factory scale, not any specific awardee’s operational performance.
The ACC battery manufacturing geography in India as at the current commissioning window is concentrated in Gujarat (Reliance New Energy Storage Jamnagar integrated giga-facility), Tamil Nadu (Ola Electric Cell Technology Krishnagiri), Karnataka (Rajesh Exports JV), and Andhra Pradesh (Amara Raja Advanced Cell Technologies). Each site is greenfield or brownfield giga-scale, with total capex commitments running into thousands of crores per GWh of committed capacity. The vendor-BOM plan for the DVA ramp from a 25 percent Year 1 baseline to a 60 percent Year 5 target requires a parallel domestic ecosystem build for cathode active material (currently 100 percent imported from China and South Korea, with domestic capacity being built by Rajesh JV and Amara Raja early-stage plants), anode (graphite import today, domestic build underway), electrolyte (imported today with Neogen Chemicals and Gujarat Fluorochemicals building domestic capacity), separator (imported today), and can and casing (existing India can-manufacturing base). The PLI ACC battery DVA 25 to 60 percent ramp reconciliation sibling walks the year-by-year DVA ramp mechanic in depth; the current article focuses on the GWh milestone and capex tracking layer.
The regulatory overlay — DHI PLI ACC scheme, GWh commitment, milestone-linked disbursement, show-cause mechanism
Four regulatory anchors govern the PLI ACC Battery GWh milestone reconciliation, and each maps to a specific control surface.
The DHI PLI ACC Battery scheme (Rs 18,100 crore outlay, notified by the Department of Heavy Industries under the Ministry of Heavy Industries) requires awardees to establish a minimum 5 GWh of committed capacity per applicant with commissioning within 2 years of the Letter of Award date and full committed capacity operational within 5 years. The scheme is technology-agnostic across Lithium Iron Phosphate (LFP), Nickel Manganese Cobalt (NMC), and other cell chemistries — DHI evaluates the awardee’s technology proposal on energy density (Wh per kg), safety per DHI-approved technology partner qualification, and specific gravimetric energy performance targets. Named awardees per PIB DHI announcements include Reliance New Energy Storage, Ola Electric Cell Technology, Rajesh Exports Karnataka JV, Amara Raja Advanced Cell Technologies, and Mahindra Susten JV. The distinction from the MNRE PLI Solar PV Modules scheme (covered in the PLI Solar PV Modules Rs 24,000 crore MNRE claim reconciliation Wave 2 cornerstone) is critical: MNRE administers the solar PLI through IREDA (Tranche-I) and SECI (Tranche-II), while DHI administers the ACC PLI directly under the Ministry of Heavy Industries, with separate portals, separate audit protocols, and separate milestone reporting cadences.
The GWh capacity commissioning milestone structure is the second regulatory anchor. Each awardee’s commissioning trajectory breaks into four anchor events referenced against the LoA date T0: T + 24 months is the pilot line commissioning milestone (typically 20 to 30 percent of committed capacity — for a 10 GWh awardee, illustratively 2 to 3 GWh — sufficient to demonstrate the chemistry, the cathode-anode-electrolyte stack, the pouch or cylindrical cell format at scale, and the initial safety qualification), T + 36 to 48 months is the partial commercial capacity milestone (typically 50 to 70 percent of committed capacity with revenue-generating cell dispatch to downstream EV OEMs, stationary storage system integrators, or two-wheeler and three-wheeler cell customers), and T + 60 months is the full committed capacity operational milestone (100 percent of committed capacity in continuous production). A fourth milestone at T + 84 months completes the 2-year post-commissioning operational-proof window for the retention balance release.
The milestone-linked disbursement schedule is the third regulatory anchor. Illustratively, the Year 2 pilot commissioning proof triggers approximately 10 percent of the committed incentive as an early tranche, the Year 3 partial commercial capacity certification triggers approximately 40 percent as the mid-window tranche, and the Year 5 full committed capacity operational milestone triggers the balance of approximately 50 percent with a portion retained until the 2-year post-commissioning operational-proof window closes at Year 7. The per-GWh indicative incentive band (illustratively Rs 400 to 600 crore per GWh over the 5-year window) applied to the certified commissioned capacity at each milestone gives the tranche amount, subject to the LoA ceiling.
The show-cause response mechanism and force-majeure claim framework is the fourth regulatory anchor. When an awardee reports commissioning capacity below the milestone target — for example a Year 2 pilot commissioning of 1.8 GWh against a 2.0 GWh milestone target on a 10 GWh committed applicant, a 0.2 GWh or approximately 10 percent shortfall — DHI issues a show-cause notice requiring the awardee to explain the shortfall within a specified window (typically 30 to 45 days) and either request an extension with justification (typically citing force majeure such as documented raw-material supply shock, specific supplier default, regulatory approval delay outside awardee control, or natural disaster) or accept a pro-rata per-GWh incentive reduction for the tranche. DHI’s assessment of the show-cause and any force-majeure claim is binding on the disbursement decision. The Ind AS 20 conditional-grant recognition on the milestone-linked tranche, the Section 115JB MAT flow-through on the recognition-basis book profit, and the Section 115BAA concessional-regime trade-off are the same accounting and tax mechanic covered for PLI schemes generally — the PLI vs MAT Minimum Alternate Tax pharma interaction and Section 115BAA vs PLI pharma concessional rate election cross-cluster references walk this in depth.
A worked example — a 10 GWh giga-factory awardee across the milestone-linked cycle
Illustrative — the following figures represent the operating pattern of a giga-factory PLI ACC Battery awardee at the scale of a 10 GWh committed applicant such as Reliance New Energy Storage with a Jamnagar Gujarat integrated giga-facility. The 2022 LoA date, the specific per-GWh indicative incentive band inside the LoA, and the actual milestone commissioning trajectory are governed by the confidential DHI bid outcome and the applicant’s own operational reporting; the numbers below are illustrative of the reconciliation surface, not a claim about any specific awardee’s actual PLI position or operational performance. Each milestone-linked disbursement tranche is subject to the applicant’s LoA ceiling; the illustrative computation below shows the reconciliation grammar.
A 10 GWh committed applicant receives a DHI Letter of Award in 2022 (T0). The milestone calendar and the illustrative commissioning trajectory unfolds as follows:
| Milestone | Anchor date | Target | Illustrative achievement | Delta |
|---|---|---|---|---|
| M1 (Y2 pilot) | April 2024 (T + 24m) | 2.0 GWh (~20% of 10 GWh) | 1.8 GWh commissioned | 0.2 GWh short (~10%) |
| M2 (Y3 partial) | April 2025 (T + 36m) | 5.0 GWh (~50%) | 4.7 GWh commissioned | 0.3 GWh short (~6%) |
| M3 (Y5 full) | April 2027 (T + 60m) | 10.0 GWh (100%) | Trajectory on-track | To be certified |
| M4 (Y7 retention) | April 2029 (T + 84m) | 2-year operational proof | Continuous window | Retention release |
At the Year 2 pilot milestone in April 2024, the 0.2 GWh shortfall against the 2.0 GWh pilot target triggers a DHI show-cause notice. The awardee files a show-cause response within the 30 to 45 day window citing the global lithium supply chain disruption of 2023 to 2024 — supported by contemporaneous evidence including supplier notice from the cathode active material vendor documenting the constrained supply, published industry indices showing the lithium spot price spike, and internal capex records demonstrating good-faith commissioning effort and specific mitigation attempts (accelerated qualification of a secondary cathode active material vendor, expedited air-freight import of interim material supply, additional working-capital deployment to buffer inventory). DHI’s assessment on the force-majeure claim accepts partial exemption, preserving the pilot milestone tranche disbursement at the full milestone rate for the certified 1.8 GWh with a partial acceptance of the 0.2 GWh gap.
At the Year 3 partial commercial milestone in April 2025, the awardee reports 4.7 GWh against the 5.0 GWh target — a 0.3 GWh shortfall or approximately 6 percent. The show-cause response for this milestone builds on the accepted force-majeure precedent from Year 2 and cites the continuing supply-side normalisation plus the acceleration of domestic cathode active material capacity build-out. DHI’s assessment triggers the mid-window disbursement tranche on the certified 4.7 GWh at the per-GWh indicative incentive band.
The illustrative milestone-linked disbursement computation on a per-GWh indicative incentive band of Rs 500 crore per GWh over the 5-year window is:
| Milestone | Illustrative certified GWh | Illustrative per-GWh band (Rs cr) | Tranche share | Illustrative tranche (Rs cr) |
|---|---|---|---|---|
| M1 (Y2 pilot) | 1.8 GWh | 500 | ~10% | ~90 |
| M2 (Y3 partial) | 4.7 GWh | 500 | ~40% | ~940 |
| M3 (Y5 full) | 10 GWh (target) | 500 | ~50% | ~2,500 (subject to retention) |
| M4 (Y7 retention) | 10 GWh (sustained) | 500 | Retention release | Balance |
The Year 5 tranche is disbursed on the milestone certification event with a portion retained until the Year 7 operational-proof window closes. The reconciliation playbook monthly close pillar situates the milestone-linked recognition entries within the entity’s monthly close cadence, ensuring the DHI milestone certification event and the Ind AS 20 recognition entry land in the correct accounting period rather than drifting into the following month’s book close.
Common reconciliation breakages
Four breakages recur across PLI ACC Battery GWh milestone reconciliation cycles.
-
Milestone GWh delta computation and grace-window interpretation. Awardees sometimes interpret the DHI grace window on milestone commissioning liberally — assuming a 10 percent tolerance is automatically forgiven, or that a milestone reported within a quarter of the anchor date is compliant regardless of the specific GWh delta. In practice DHI treats every material GWh shortfall as a show-cause trigger, and the show-cause response quality (with contemporaneous force-majeure evidence) determines the disbursement outcome. The reconciliation discipline is a strict milestone calendar keyed to the T0 anchor with 30-day quarter-end reporting cycles, a committed-capacity target curve computed against the LoA GWh commitment, and a per-milestone delta report that automatically triggers a show-cause response draft when the delta breaches a defined threshold.
-
Force-majeure claim register evidence gap. Awardees that log force-majeure claims retrospectively — assembling evidence weeks or months after the underlying event — face a harder DHI acceptance path than awardees that log claims contemporaneously with the event. Missing supplier-notice evidence, absent published industry index references, or unavailable internal capex records at the time of DHI show-cause response weakens the force-majeure defence and increases the likelihood of a pro-rata per-GWh incentive reduction. The reconciliation discipline is a contemporaneous force-majeure claim register updated in real-time as events unfold, with evidence artifacts (supplier notices, industry publications, internal capex records) linked at the entry level.
-
DHI show-cause response tracking versus disbursement receivable reconciliation. Awardees frequently maintain the DHI correspondence register in a separate silo from the finance ledger receivable tracking. This creates a lag between the DHI show-cause outcome and the Ind AS 20 recognition entry — a rejected show-cause that pro-rata reduces the tranche disbursement may not flow through to the receivable balance and the P&L recognition for the correct period, leading to over-recognition of income and under-provisioning of the Section 115JB MAT for the period. The reconciliation discipline is a unified show-cause response register with a direct link to the receivable balance and the Ind AS 20 recognition entry per milestone tranche. The reconciliation failure-mode analysis for India methodology treats the show-cause-to-receivable linkage as a specific failure mode with documented control tests.
-
Retention contingent-receivable treatment and Year 7 operational-proof documentation. The 2-year post-commissioning retention hold requires continuous operational-proof documentation (quarterly capacity utilisation reports, quarterly DVA reports, quarterly compliance affidavits) across the post-commissioning window. Awardees that treat the retention balance as a firm receivable prematurely (recognising the retention amount in book profit before the release condition is met) create a book-tax exposure and a potential audit qualification. The reconciliation discipline is a distinct retention contingent-receivable sub-ledger with Ind AS 20 recognition deferred until reasonable assurance of the retention release condition is established. The 57 human errors and the detection envelope trust asset situates the recognition-timing error class within the broader taxonomy of process failures.
How a reconciliation platform handles this
A purpose-built electronics reconciliation platform ingests the DHI Letter of Award milestone calendar, the awardee’s quarter-on-quarter commissioning capex ledger from SAP FI or Oracle Fusion, the per-plant-line commissioning schedule (cathode active material plant, anode plant, electrolyte plant, cell assembly, module and pack assembly), the DHI portal quarterly reporting workbook with TPIA capacity certification, energy density lab report, safety qualification test report, and per-stage DVA workbook, the DHI show-cause response register with every inquiry logged, and the force-majeure claim register with contemporaneous evidence — and produces a milestone-linked disbursement reconciliation workbook that binds the GWh milestone calendar, the actual quarter-on-quarter commissioning trajectory, the DHI portal reporting cycle, the show-cause response outcomes, the force-majeure claim acceptance status, and the Ind AS 20 conditional-grant recognition and Section 115JB MAT flow-through into one continuous audit trail across the 5-year commissioning window and the 2-year post-commissioning retention window. Match rate improvement from 51 to 88 percent on the milestone-vs-actual GWh reconciliation, the capex-to-commissioning-line tracking, the show-cause response linkage to the receivable balance, and the retention contingent-receivable tracking — combined with an ISO 27001:2022 posture, AWS Mumbai residency, and DPDP Act 2023 aligned data handling — is what makes the platform an infrastructure investment for a giga-factory PLI ACC Battery awardee rather than a spreadsheet substitute. The commercial pillar is Electronics reconciliation software India; the broader authority is reconciliation software India.

- ▸ PLI Scheme for Advanced Chemistry Cell (ACC) Battery Storage, Department of Heavy Industries — The Production Linked Incentive Scheme for Advanced Chemistry Cell Battery Storage is administered by the Department of Heavy Industries under the Ministry of Heavy Industries with a total outlay of Rs 18,100 crore. Awardees commit to establishing minimum 5 GWh of capacity per applicant with commissioning within 2 years of the Letter of Award date and full committed capacity operational within 5 years. The scheme is technology-agnostic across Lithium Iron Phosphate, Nickel Manganese Cobalt, and other cell chemistries evaluated on energy density, safety, and specific gravimetric energy performance targets. Incentive disbursement is milestone-linked over the 5-year commissioning trajectory — pilot line commissioning proof at Year 2 triggers the initial disbursement tranche, partial commercial capacity certification at Year 3 triggers the mid-window tranche, and full committed capacity operational at Year 5 triggers the balance subject to a 2-year post-commissioning operational-proof retention hold.
- ▸ DHI PLI ACC Award Announcement and Awardee Selection — The Department of Heavy Industries has awarded approximately 50 GWh of aggregate committed capacity across the anchor beneficiaries selected under the ACC Battery PLI competitive bid. Named awardees per PIB DHI announcements include Reliance New Energy Storage (10 GWh Jamnagar Gujarat), Ola Electric Cell Technology (10 GWh Krishnagiri Tamil Nadu with commissioning ongoing FY 2025-26), Rajesh Exports Karnataka JV (5 GWh phase 1), Amara Raja Advanced Cell Technologies Andhra Pradesh (5 GWh), and Mahindra Susten JV. Each awardee's Letter of Award carries a per-applicant GWh commitment, a per-GWh indicative incentive band over the 5-year window, and a milestone-linked disbursement schedule with show-cause response triggers on any GWh shortfall against a milestone window.
- ▸ Ind AS 20, Accounting for Government Grants and Disclosure of Government Assistance — Notified by the Ministry of Corporate Affairs as part of the Companies (Indian Accounting Standards) Rules 2015 and subsequent amendments. Government grants related to income are recognised in profit or loss on a systematic basis over the periods in which the entity recognises as expenses the related costs for which the grants are intended to compensate. For a milestone-linked PLI ACC Battery disbursement, recognition aligns with each milestone certification event — pilot commissioning proof at Year 2, partial commercial capacity certification at Year 3, full committed capacity operational at Year 5. The 2-year post-commissioning retention hold triggers a distinct recognition treatment because reasonable assurance of the retention release depends on continued operational compliance across the post-commissioning window.
- ▸ Section 115JB MAT and Section 115BAA Concessional Regime, Income-tax Act — Section 115JB imposes Minimum Alternate Tax at 15 percent (plus surcharge and cess) on book profit for companies with book profit exceeding total income computed under normal provisions. Section 115BAA provides an alternate concessional regime at 22 percent (plus surcharge and cess) with the entity exempt from MAT but forfeiting several incentive claims including additional depreciation under Section 32(1)(iia) and specific loss carry-forward adjustments. For a milestone-linked PLI ACC grant recognised under Ind AS 20 as income, the recognition-basis book profit for the year flows into the Section 115JB MAT base; an awardee that has opted into Section 115BAA is exempt from MAT but forfeits associated incentives, and the trade-off is re-evaluated at each milestone as the grant recognition trajectory clarifies against the 5-year window.
