A finance controller for a mid-market Indian manufacturing corporate opens the AP invoice queue on the morning of Day 5 of the monthly close. Three invoices are waiting for a capitalisation-versus-expense call. The first is a Rs 5 lakh air-conditioner replacement at the head office. The second is a Rs 40 lakh MoEFCC Environmental Impact Assessment consultancy fee for a chemical plant expansion still under construction. The third is a Rs 30 crore auction premium for an iron-ore mining lease acquired under the MMDR Act 1957. The accountant wants a call before the fixed-asset register is closed for the month and the depreciation schedule is finalised. The tax executive wants the same call before the current tax and deferred tax working papers are prepared. Get one wrong and the audit adjustment surfaces two years later with a Section 43(6) block-of-assets restatement, a deferred tax reversal under Ind AS 12, and a Section 271(1)(c) concealment allegation if the department reads the misclassification as intentional.
Every invoice that lands in AP falls into one of two accounting classifications — capex on the balance sheet or revenue expense in the P&L — through six sequential tests. Test 1 (Ind AS 16 paragraph 7) — does the item produce economic benefits over more than one accounting period AND can the cost be measured reliably? If both, it is capex on tangible property, plant and equipment. Test 2 (Ind AS 38 paragraph 8) — if the item has no physical substance, is it identifiable (separable or arising from contractual or other legal rights)? If yes, apply the six-limb Ind AS 38 development-phase test; if pass, capex on intangible assets. Test 3 (Section 37(1) IT Act) — if the item passes neither Test 1 nor Test 2, is the expenditure wholly and exclusively for the purposes of the business AND not in the nature of capital expenditure? If both, revenue expense deductible in the year incurred. Test 4 (Ind AS 16 paragraph 12–14) — for a subsequent cost on an existing asset, does the replacement increase the asset's capacity, useful life, or output quality (capital repair) or restore the original condition (revenue repair)? The two attract opposite treatments even though the invoice looks identical. Test 5 (Ind AS 16 paragraph 16 + Ind AS 23) — for a pre-operative expenditure on an asset still under construction, is the cost directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management? If yes, capitalise until the ready-for-use date. Test 6 (Ind AS 12 paragraph 15 + Section 32 + Section 43(6)) — once capitalised, the Section 43(6) block WDV depreciation and the Ind AS 16 straight-line depreciation open a temporary difference, and the differential feeds the deferred tax liability or deferred tax asset in the P&L.
A capex-versus-revenue decision worksheet on the AP invoice queue that logs each of the six tests with a yes/no outcome and a supporting reference (Ind AS 16 paragraph, Section 37 note, Section 32 block code). A fixed-asset register that captures both the Ind AS 16 book carrying amount (cost, additions, depreciation, disposals, closing carrying amount) and the Section 43(6) tax WDV in parallel columns, with the temporary difference computed for every asset for every reporting period. A pre-operative expenditure schedule for every capital work-in-progress project that captures the directly attributable costs (consultancy fees, borrowing costs under Ind AS 23, site preparation, installation, testing) with the ready-for-use date and the trigger point for capitalisation cessation. A deferred tax reconciliation under Ind AS 12 that reconciles the opening deferred tax balance to the closing balance through the movements in the book-tax temporary differences on every asset. A capex-versus-revenue policy note approved by the audit committee that documents the entity's thresholds (a de-minimis floor below which small-ticket items are expensed even if strictly capitalisable, an internally consistent cut-off between capital repair and revenue repair, a standard treatment for demonstrated pre-operative expenditure).
Every invoice landing in AP is routed through the six-test worksheet, classified as capex on Ind AS 16, capex on Ind AS 38, revenue expense under Section 37, capital repair under Ind AS 16 paragraph 13, revenue repair under Ind AS 16 paragraph 12, or pre-operative capitalisation on capital work-in-progress. The fixed-asset register ties to the Section 43(6) block-of-assets movement on a monthly basis, with the temporary difference computed and the deferred tax adjustment posted. The pre-operative capitalisation window closes on the ready-for-use date recorded by the project engineer, and the borrowing cost stops capitalising under Ind AS 23. The Ind AS 12 deferred tax working paper reconciles opening to closing on an asset-by-asset basis with the movement in the temporary difference explained. The audit trail on any specific capitalisation-versus-expense call is defensible against a Section 143(3) scrutiny assessment, a statutory audit challenge on Ind AS 16 or Ind AS 38 recognition, or a subsequent Section 263 revision proceeding on a completed assessment. The finance function's classification discipline is what closes the two-year audit-adjustment tail into a defensible working paper filed with the return.
The head office AC failed over the weekend. The vendor replaced it on Monday morning. The invoice is for Rs 5 lakh. The accountant is asking whether to add it to the building block and depreciate it, or expense it in the P&L for the month.
Two more invoices in the same queue. A Rs 40 lakh MoEFCC Environmental Impact Assessment consultancy fee against the chemical plant expansion. A Rs 30 crore auction premium against an iron-ore mining lease. The finance manager wants a call before the fixed-asset register is closed for the month, and the tax executive wants the same call before the current tax and deferred tax working papers land.
Where does each rupee sit — the balance sheet or the P&L?
The quick answer
Every invoice that lands in AP passes through six sequential tests. Test 1 is Ind AS 16 recognition — does the item produce economic benefits over more than one accounting period AND can the cost be measured reliably? Test 2 is Ind AS 38 identifiability — for items with no physical substance, is it separable or arising from a legal right? Test 3 is Section 37 — is the expenditure wholly-and-exclusively for the business AND not in the nature of capital expenditure? Test 4 is the capital-repair versus revenue-repair distinction — does the replacement increase capacity, useful life, or output quality, or does it restore original condition? Test 5 is pre-operative capitalisation — for costs on an asset still under construction, is the cost directly attributable to bringing the asset to the ready-for-use state? Test 6 is the book-tax gap — once capitalised, the Section 43(6) WDV depreciation and the Ind AS 16 straight-line open a temporary difference that feeds the Ind AS 12 deferred tax working paper.
Get any one test wrong and the audit adjustment surfaces two years later with a Section 43(6) block-of-assets restatement, a deferred tax reversal, and a going-concern note in the financials.
Test 1 — Ind AS 16 recognition (economic benefits over more than one period)
Ind AS 16 paragraph 7 sets the primary capex threshold in two limbs. Limb one — it must be probable that future economic benefits associated with the item will flow to the entity. Limb two — the cost of the item can be measured reliably. Both limbs, or the item is expensed.
The first limb is a horizon test. An item that produces benefits only in the current accounting period — a stationery order, a monthly SaaS subscription, a security guard’s salary — fails the horizon test and is expensed. An item that produces benefits over more than one accounting period — a plant, a machine, a building, a delivery vehicle — passes the horizon test and moves to the second limb.
The second limb is a measurement test. An item whose cost is bundled inside a services contract with no separate breakdown (the training component of a software implementation package, the maintenance component of a plant supply contract) fails the measurement test on the un-separable component and is expensed. An item whose cost is a stand-alone invoice or a separable line in a contract passes both limbs and capitalises.
Test 2 — Ind AS 38 identifiability (intangible without physical substance)
If the item has no physical substance — a software licence, a patent, a trademark, an in-licensed technology know-how — Ind AS 38 paragraph 8 governs. The identifiability test is the first Ind AS 38 gate. An intangible is identifiable if it is either separable (capable of being sold, transferred, licensed, rented, or exchanged) or arises from contractual or other legal rights. A perpetual software licence is separable and identifiable. A general market study bundled with an M&A retainer is neither separable nor a legal right, and is expensed.
For internally generated intangibles (R&D, self-developed software, self-created brand), Ind AS 38 paragraphs 54 and 57 layer a second gate — research phase expenditure is expensed; development phase expenditure is capitalised only when the six-limb test (technical feasibility, intention to complete, ability to use or sell, future economic benefit, resources to complete, measurement of directly attributable cost) is met. The /insights/ind-as-38-r-and-d-capitalisation-vs-section-35-2ab-pharma/ sibling walks through the R&D capitalisation call against the Section 35(2AB) super-deduction interaction — an illustrative case where Ind AS 38 capitalises the development-phase cost and Section 35(2AB) allows a 100 per cent deduction of the same cost, creating a large Ind AS 12 deferred tax adjustment on Day 1.
Test 3 — Section 37 (wholly-and-exclusively for business, not capital in nature)
If the item fails both the Ind AS 16 and the Ind AS 38 tests, Section 37(1) of the Income-tax Act 1961 is the next gate. Section 37 allows any expenditure laid out wholly and exclusively for the purposes of the business or profession — provided the expenditure is not covered by Sections 30 to 36 and is not in the nature of capital expenditure.
The two carve-outs are what most classification disputes turn on. The wholly-and-exclusively test excludes personal or dual-use expenditure — a director’s personal insurance, a mixed-use company car with substantial private use, entertainment that shades into hospitality with no business connection. The not-in-the-nature-of-capital carve-out excludes any outlay that Ind AS 16 or Ind AS 38 would have capitalised — the two provisions run in the same direction, and a Section 37 claim on a capex-classified item is disallowed on the second carve-out.
The /insights/cgmp-remediation-consulting-fees-section-37-deduction-pharma/ sibling walks through an illustrative pharma case where a Rs 8 crore remediation consulting fee is claimed under Section 37 — the wholly-and-exclusively test is met, and the not-in-the-nature-of-capital test is met because the remediation restores compliance to run existing capacity rather than adding new capacity or extending useful life.
Test 4 — capital repair versus revenue repair
The Rs 5 lakh AC replacement at the head office is the classic Test 4 case. Ind AS 16 paragraphs 12–14 draw the line. Day-to-day servicing costs — labour, consumables, small parts — are always expensed. But parts of items of property, plant and equipment may require replacement at regular intervals, and where the recognition criteria are met, the entity recognises in the carrying amount the cost of the replacement part with derecognition of the replaced component.
The operative test — does the replacement increase the asset’s capacity, useful life, or output quality (capital repair) or restore the original condition (revenue repair)?
The illustrative AC case. A mid-market office replaces a broken 5-tonne rooftop AC with an identical 5-tonne rooftop unit. The Rs 5 lakh restores original cooling capacity, does not extend the building’s useful life, does not improve output quality. It is a revenue repair, expensed in the P&L, deducted under Section 37 in the year incurred.
Change one variable — the office replaces the failed 5-tonne rooftop AC with a 7.5-tonne inverter unit rated three stars higher on energy efficiency. The higher capacity satisfies the capacity-increase limb, the higher star rating extends the useful life through lower thermal stress on the compressor. The Rs 5 lakh capitalises to the building block, depreciates at 10 per cent WDV under Section 32, and the carrying amount of the replaced 5-tonne unit is derecognised. The /insights/tds-tooling-payment-capital-vs-revenue-auto-india/ sibling walks through the analogous auto-component tooling case with a Section 194C TDS overlay.
Test 5 — pre-operative capitalisation until the asset is ready for use
The Rs 40 lakh MoEFCC EIA consultancy fee is the pre-operative case. Ind AS 16 paragraph 16(b) provides that the cost of an item of property, plant and equipment includes any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management. The Ind AS 23 borrowing-cost rule stacks on top for financing costs.
An EIA report is a statutory precondition to the CTE/CTO clearance without which the chemical plant cannot be commissioned. It is directly attributable to bringing the plant into the ready-for-use state. The Rs 40 lakh capitalises against the plant cost as pre-operative expenditure, and the depreciation clock only starts on the ready-for-use date. The /insights/moefcc-cte-cto-clearance-chemical-plant-cost-accounting-india/ cornerstone lays out the full CTE-CTO-EIA sequence and the specific line items that capitalise against the plant cost versus those that expense.
The parallel cement-plant case at /insights/waste-heat-recovery-cement-plant-captive-power-cost-accounting-india/ walks through a Rs 180 crore waste heat recovery captive power unit — capitalised as Ind AS 16 property, plant and equipment with a 20-year straight-line useful life against a Section 43(6) 15 per cent WDV plant-and-machinery block. The pre-operative capitalisation window closes on the commissioning date; every rupee of borrowing cost from that date forward is a P&L finance cost under Ind AS 23 paragraph 22.
Test 6 — the Section 43(6) versus Ind AS 16 gap and the Ind AS 12 consequence
Once an item is capitalised, the book depreciation method under Ind AS 16 paragraph 62 and the tax depreciation method under Section 32 read with Section 43(6) rarely match. Ind AS 16 typically uses straight-line over the entity-assessed useful life. Section 43(6) uses written-down value on a class of assets at the rate prescribed in the Income-tax Rules 1962 Appendix I — 10 per cent on buildings, 15 per cent on plant and machinery, 25 per cent on intangibles (including mining rights), 40 per cent on computers and computer software.
The Rs 30 crore iron-ore mining lease auction premium is the Test 6 case in extreme form. Under Section 32, the mining right depreciates at 25 per cent WDV — Rs 7.5 crore in Year 1, Rs 5.625 crore in Year 2, Rs 4.22 crore in Year 3. Under Ind AS 16, the same mining right is depreciated on units-of-production over the estimated recoverable reserves — for a 20-year lease that maps to roughly Rs 1.5 crore straight-line-equivalent per year. The Section 43(6) tax deduction of Rs 7.5 crore in Year 1 against the Ind AS 16 book charge of Rs 1.5 crore in Year 1 opens a Rs 6 crore temporary difference in Year 1 alone.
The Ind AS 12 paragraph 15 rule kicks in — the book carrying amount (Rs 30 crore minus Rs 1.5 crore = Rs 28.5 crore at end of Year 1) exceeds the tax WDV (Rs 30 crore minus Rs 7.5 crore = Rs 22.5 crore at end of Year 1), and the Rs 6 crore differential attracts a deferred tax liability at the applicable tax rate. The /insights/mmdr-act-1957-iron-ore-mining-lease-steel-industry-cost-reconciliation/ cornerstone walks through the auction-premium arithmetic year by year with the deferred tax liability rollup.
The fixed-asset register that captures both the Ind AS 16 carrying amount and the Section 43(6) tax WDV in parallel columns is the operational source of truth. The /insights/fixed-asset-reconciliation-india/ pillar walks through the register-to-block tie-out and the monthly deferred tax adjustment posting.
The one to escalate first — the tax gap on a large capex
Of the six tests, Test 6 is the one that most materially moves the P&L in the year the classification lands. A Rs 30 crore capitalisation that opens a Rs 6 crore temporary difference in Year 1 pushes a Rs 1.5 crore deferred tax liability onto the balance sheet at 25 per cent tax rate, and a Rs 1.5 crore deferred tax charge into the current-year P&L. A misclassification of the same Rs 30 crore as revenue expense — a Section 37 claim rather than a Section 32 depreciation — surfaces at the Section 143(3) scrutiny assessment two years later with a Rs 30 crore disallowance, a full-year interest charge under Section 234B, and a Section 271(1)(c) concealment allegation if the department reads the claim as intentional.
The finance function’s escalation ladder on any capex-versus-revenue call above the entity’s materiality threshold (typically Rs 25 lakh for a mid-market corporate, Rs 1 crore for a large-cap) should route the call to the tax executive for the Section 32 versus Section 37 tie-out before the AP invoice is posted, and to the audit committee for the Ind AS 16 versus Ind AS 38 classification before the year-end financials are approved.
When the manual capex-versus-revenue call outgrows itself
For a mid-market entity with fewer than 200 capex additions per year and a single AP hub, the six-test worksheet fits inside the Day 5 to Day 10 window of the monthly close, and one senior accountant paired with the tax executive can hold it. The Ind AS 12 deferred tax reconciliation runs quarterly with a full audit-committee review at year-end. The register-to-block tie-out is a monthly ritual.
Above 500 capex additions per year — or above the point where the pre-operative capital work-in-progress schedule holds more than 20 concurrent projects each with its own ready-for-use date and its own borrowing-cost capitalisation window — the manual six-test worksheet leaks. A pre-operative fee misclassified as revenue expense, a like-for-like replacement wrongly capitalised, a mining right depreciated on the wrong block, a deferred tax movement missed on a capitalised software licence. Each miss surfaces two audit cycles later with a compounding restatement.
At that scale, moving the fixed-asset register, the Section 43(6) block movement, and the Ind AS 12 deferred tax working paper onto continuously refreshed detection — where Terra Insight’s reconciliation software treats the register-to-block tie-out and the temporary-difference movement as first-class monthly outputs — is what keeps the year-end audit inside a two-week cycle rather than a rolling restatement queue. Below that scale, the six-test worksheet paired with a well-maintained fixed-asset register is the right tool.

Frequently Asked Questions
How do I decide whether a Rs 5 lakh air-conditioner replacement is capex or revenue?
Apply Ind AS 16 paragraph 12–14. If the new AC restores the original cooling capacity of a broken like-for-like unit and does not extend the building’s useful life or increase its output quality, the Rs 5 lakh is a revenue repair — expensed in the P&L, deducted under Section 37 in the same year. If the new AC increases the total cooling capacity (a larger unit, additional zones covered, higher energy-efficiency rating that extends the useful life), the Rs 5 lakh is a capital replacement — added to the building block, depreciated at 10 per cent WDV under Section 32, straight-lined over the remaining useful life under Ind AS 16, and the carrying amount of the replaced part is derecognised. The illustrative case where a mid-market office replaces a 5-tonne rooftop AC with a 7.5-tonne inverter unit — the higher capacity plus the higher star rating together satisfy both the capacity-increase test and the useful-life extension test, so the Rs 5 lakh capitalises.
The MoEFCC EIA consultancy fee was Rs 40 lakh for a chemical plant expansion. Where does it sit?
The Rs 40 lakh MoEFCC Environmental Impact Assessment consultancy fee is a pre-operative expenditure directly attributable to the plant expansion. Under Ind AS 38 paragraph 66, an internally generated intangible asset arising from development is recognised if the six-limb test (technical feasibility, intention, ability, future economic benefit, resources, measurement) is met, and until the asset is ready for its intended use the directly attributable pre-operative expenditure capitalises against the underlying tangible or intangible asset. For a chemical plant expansion where the EIA report is a statutory precondition to the CTE/CTO clearance without which the plant cannot be commissioned, the Rs 40 lakh capitalises against the plant cost under Ind AS 16 paragraph 16(b) — costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management. The full treatment is at the /insights/moefcc-cte-cto-clearance-chemical-plant-cost-accounting-india/ cornerstone.
Section 32 depreciation is on WDV and Ind AS 16 depreciation is straight-line. What do I do with the gap?
The gap is a temporary difference under Ind AS 12 paragraph 15 and creates either a deferred tax liability or a deferred tax asset. In the early years of an asset’s life, the Section 43(6) WDV depreciation (say 15 per cent on plant and machinery) exceeds the Ind AS 16 straight-line depreciation (say 8 per cent on a 12-year useful life), so the tax written-down value drops faster than the book carrying amount. The book carrying amount exceeds the tax WDV, and the differential attracts a deferred tax liability at the applicable tax rate. In the later years the reverse happens — the Section 43(6) WDV asymptotes toward zero while the Ind AS 16 straight-line continues at the constant annual figure, the tax WDV catches up to the book carrying amount, and the deferred tax liability unwinds. Every capitalised asset that carries a book-tax method difference feeds this Ind AS 12 computation, and the fixed-asset reconciliation is the source of the movement — the /insights/fixed-asset-reconciliation-india/ pillar walks through the register-to-block tie-out.
The plant is still under construction. Can I capitalise the interest on the term loan financing the build?
Yes, under Ind AS 23 (Borrowing Costs) as read with Ind AS 16 paragraph 16(c) — borrowing costs directly attributable to the acquisition, construction, or production of a qualifying asset are capitalised as part of the cost of that asset. A qualifying asset is one that necessarily takes a substantial period of time to get ready for its intended use or sale — a chemical plant, a cement kiln, a waste heat recovery captive power unit at a cement facility (see /insights/waste-heat-recovery-cement-plant-captive-power-cost-accounting-india/), a semiconductor fab. Capitalisation commences when the entity is incurring expenditure on the asset, incurring borrowing costs, and undertaking activities necessary to prepare the asset for its intended use. Capitalisation ceases when substantially all activities necessary to prepare the qualifying asset for its intended use are complete. From that point the borrowing cost is charged to the P&L as finance cost under Ind AS 23 paragraph 22, and the pre-operative capitalisation window closes. The date the asset is ready for its intended use — not the date of commercial production — is the boundary.
The Rs 30 crore auction premium for an iron-ore mining lease under MMDR — is that capex?
Yes, the auction premium is a Section 43(6) block-of-assets addition and an Ind AS 16 (or Ind AS 38, depending on whether the lease is treated as a tangible plant right or an intangible mineral right) capitalisation. Under Section 32, mining leases attract 25 per cent WDV depreciation as intangible assets (Income-tax Rules 1962 Appendix I). Under Ind AS 16 the mineral extraction right is depreciated on a units-of-production basis over the estimated recoverable reserves, which for a large iron-ore lease can run 15 to 20 years straight-line-equivalent. The 25 per cent WDV versus the 15-to-20-year straight-line creates a large front-loaded Section 43(6) tax deduction against a back-loaded Ind AS 16 book charge, and the resulting deferred tax liability under Ind AS 12 for the first five years can materially move the effective tax rate the CFO reports in the Ind AS financials. The /insights/mmdr-act-1957-iron-ore-mining-lease-steel-industry-cost-reconciliation/ cornerstone walks through the full reconciliation with the auction-premium arithmetic laid out.

- ▸ Ind AS 16 paragraph 7, Property, Plant and Equipment (MCA) — The cost of an item of property, plant and equipment shall be recognised as an asset if, and only if, it is probable that future economic benefits associated with the item will flow to the entity, and the cost of the item can be measured reliably. The two-limb recognition threshold is the primary capex test. An item that produces economic benefits over more than one accounting period but whose cost cannot be measured reliably (typically because it is bundled inside a services contract with no separate cost breakdown) fails the second limb and is expensed. An item whose cost is measurable but which does not produce economic benefits beyond the current period (typically a consumable spare or a like-for-like repair that restores original condition) fails the first limb and is expensed under Ind AS 16 paragraph 12.
- ▸ Ind AS 16 paragraph 12–14, subsequent costs — repairs versus improvements — An entity does not recognise in the carrying amount of an item of property, plant and equipment the costs of the day-to-day servicing of the item. Rather, these costs are recognised in profit or loss as incurred. Costs of day-to-day servicing are primarily the costs of labour and consumables, and may include the cost of small parts. The purpose of these expenditures is often described as for the repairs and maintenance of the item of property, plant and equipment. Parts of some items of property, plant and equipment may require replacement at regular intervals — where the recognition criteria are met, the entity recognises in the carrying amount of the item of property, plant and equipment the cost of the replacement part when that cost is incurred. The carrying amount of the replaced part is derecognised. This is the operative source of the capital-repair versus revenue-repair distinction: a replacement that increases the asset's capacity, useful life, or output quality qualifies for capitalisation with derecognition of the replaced component; a like-for-like restoration of original condition is expensed.
- ▸ Ind AS 38 paragraph 8, Intangible Assets — An intangible asset is an identifiable non-monetary asset without physical substance. An asset is identifiable if it either is separable — capable of being separated or divided from the entity and sold, transferred, licensed, rented or exchanged — or arises from contractual or other legal rights, regardless of whether those rights are transferable or separable from the entity or from other rights and obligations. The identifiability test is what separates a capitalisable licence, software, patent, or brand from an expensed training fee, general advertisement, or research phase cost. Ind AS 38 paragraphs 54 and 57 further prohibit capitalisation of research phase expenditure and permit capitalisation of development phase expenditure only when six criteria (technical feasibility, intention, ability, future economic benefit, resources, measurement) are all met — the six-limb development-phase test is the second Ind AS 38 gate after identifiability.
- ▸ Section 37(1), Income-tax Act 1961 — Any expenditure (not being expenditure of the nature described in Sections 30 to 36 and not being in the nature of capital expenditure or personal expenses of the assessee), laid out or expended wholly and exclusively for the purposes of the business or profession shall be allowed in computing the income chargeable under the head Profits and gains of business or profession. The Section 37 revenue-expense allowance is the primary income tax test after the Ind AS 16 and Ind AS 38 book classification. The two carve-outs matter — the wholly and exclusively for business test excludes personal or dual-use expenditure, and the not being in the nature of capital expenditure carve-out excludes any outlay that Ind AS 16 or Ind AS 38 would classify as capex. The judicial doctrine reads Section 37 alongside Section 32 tax depreciation — if the item is capex it is not deductible under Section 37, and if the item is revenue it is not depreciable under Section 32.
- ▸ Section 32 and Section 43(6), Income-tax Act 1961 — tax depreciation and block-of-assets — Section 32 provides for depreciation on tangible assets used for the purpose of business at the rate prescribed in the Income-tax Rules 1962 Appendix I, computed on the written-down value of a block of assets. Section 43(6) defines the block-of-assets — the aggregate of the written-down value of all the assets falling within a class of assets, comprising tangible assets being buildings, machinery, plant or furniture. Additions to a block during the year at more than half the year (asset put to use before 3 October) attract the full-year rate; additions in the second half attract 50 per cent of the rate. Common block depreciation rates for the Ind AS 16 asset universe include 10 per cent for buildings, 15 per cent for plant and machinery, 40 per cent for computers and computer software, and 30 per cent for motor vehicles for hire. The tax depreciation is on WDV under a Section 43(6) block; the book depreciation is typically straight-line under Ind AS 16 paragraph 62 — the timing gap this opens up is the Ind AS 12 deferred tax computation on every capitalised item.
- ▸ Ind AS 12 paragraph 15–17, Income Taxes — deferred tax on timing differences — A deferred tax liability shall be recognised for all taxable temporary differences, except to the extent that the deferred tax liability arises from the initial recognition of goodwill, or the initial recognition of an asset or liability in a transaction which is not a business combination and, at the time of the transaction, affects neither accounting profit nor taxable profit. Every capitalised asset creates a temporary difference — the Ind AS 16 carrying amount on straight-line depreciation drifts against the Section 43(6) block WDV on the tax-rate depreciation, and the differential attracts a deferred tax liability (where the book carrying amount exceeds the tax written-down value) or a deferred tax asset (the reverse). The reconciliation between the book fixed-asset register and the Section 43(6) block movement is what feeds the current tax and the deferred tax lines in the P&L, and any capex-versus-revenue misclassification at recognition propagates into both.
