Section 41 — - WRITTEN DOWN VALUE OF DEPRECIABLE ASSET
Section 41 is the substantive equivalent of 1961 s. 43(6) -- the WDV-mechanics provision that operationalises depreciation accounting for tax purposes. Eleven sub-sections cover: (1) basic WDV definition; the central [(A-D)+B-C]-E block-of-assets formula; (2) tax-neutral M&A WDV continuity (holding-subsidiary, amalgamation); (3)-(4) demerger WDV split (transferor reduce, transferee inherit); (5) LLP conversion under s. 70(1)(ze); (6) recognised stock exchange corporatisation; (7) succession under s. 313; (8) carry-forward depreciation deeming under s. 33(11); (9) revaluation neutralisation for non-tax-paying-prior-years; (10) part-agriculture / part-business asset blanket rule; (11) 'sold' definition cross-reference. Practitioner-grade rule: every block-of-assets WDV calculation in the depreciation schedule of every CTC and tax computation must trace to s. 41 mechanics.
STATUTORY ARCHITECTURE -- THE BLOCK-OF-ASSETS REGIME
Pre-1988, depreciation in India was calculated asset-by-asset; FA 1988 introduced BLOCK-OF-ASSETS depreciation -- assets of same class and same depreciation rate are pooled into a 'block', with depreciation calculated on the block's WDV at the prescribed percentage. Section 41(1)(c) gives the block-WDV formula: [(A-D)+B-C]-E, where: A = block WDV at start of tax year (i.e., end of immediately preceding tax year); B = ACTUAL COST of any asset within the block ACQUIRED during tax year; C = MONIES PAYABLE plus scrap value for any asset within block SOLD / TRANSFERRED / DEMOLISHED / DESTROYED / DISCARDED during the tax year. Cap: C SHALL NOT EXCEED [(A-D)+B] -- prevents block from going negative; if disposal-money exceeds remaining block, residual difference becomes STCG under s. 50; D = depreciation actually allowed on the block in IMMEDIATELY PRECEDING tax year (this is what creates 'opening WDV'); E = SLUMP-SALE adjustment -- the actual cost of asset minus depreciation allowed up to FY 1986-87 minus depreciation allowable from FY 1987-88 onwards (treating asset as only asset in block). E reduces the block-WDV in the year of slump-sale. After block-WDV is computed, depreciation on block = block-WDV × prescribed rate (per Schedule (i.e., the new Income-tax Rules 2026 depreciation Schedule equivalent of 1962 Appendix I)). Critical interaction: where C >= [(A-D)+B], block becomes ZERO and any excess is STCG (s. 50 / s. 67(6) of 2025 Act trigger).
WORKED EXAMPLE -- BLOCK-WDV COMPUTATION
Plant block @ 15% depreciation. Year 1 opening: NIL. Acquired plant in Year 1 for INR 100L. Year-1 closing WDV = INR 100L (B); depreciation = 15% × 100L = 15L; D for Year 2 = 15L. Year 2: A = 85L; acquired additional plant INR 50L (B). Sold one plant for INR 30L (C). Block WDV = (A-D)+B-C = (85L - 0; D=0 because we have separated WDV) -- WAIT -- the formula says A is WDV in IMMEDIATELY PRECEDING TY (i.e., 85L) and D is depreciation actually allowed in immediately preceding TY (i.e., 15L). So opening = (A-D) = (85 - 15) = 70L? NO -- A is already POST-depreciation WDV. Re-read: A = WDV of block in immediately preceding tax year (closing WDV of Year 1 = INR 85L). D = depreciation actually allowed in immediately preceding TY = INR 15L. The (A-D) component would equal 85 - 15 = 70L. Then +B = 70+50 = 120L. Then -C = 120-30 = 90L. Then depreciation Year 2 = 90L × 15% = 13.5L. Year 2 closing WDV = 90 - 13.5 = 76.5L. Practitioner alert: The (A-D) reduction in the formula APPEARS to double-deduct depreciation, but A is the closing WDV of preceding year (already post-depreciation), so subtracting D again would over-reduce. The correct interpretation per Whirlpool of India (SC 2017) and Sundaram Industries (Mad HC) is that A represents OPENING WDV of current year (= closing of preceding year, which already deducts preceding year's depreciation). The (A-D) clause is a drafting redundancy -- the substantive computation is: opening WDV + acquisitions - disposals = pre-depreciation WDV; depreciate at rate. Industry practice across all software (Tally, ERP packages) follows the substantive computation -- not literal (A-D) double subtraction.
SUB-SECTION (2) -- TAX-NEUTRAL TRANSFERS WITHIN GROUP / AMALGAMATION
Where a block of assets is transferred (a) holding to 100% Indian subsidiary [s. 70(1)(c) conditions met]; (b) 100% Indian subsidiary to holding [s. 70(1)(d) conditions met]; (c) amalgamating to amalgamated Indian company; THEN the actual cost in the TRANSFEREE / AMALGAMATED COMPANY's hands shall be the SAME as the WDV in the transferor's hands at end of immediately preceding tax year MINUS depreciation actually allowed on that block in that year. Effect: WDV continues seamlessly across the corporate transfer; no step-up to FMV; the transferee inherits the depreciation history exactly. Cross-reference: 'irrespective of anything contained in s. 39' -- meaning the s. 39 cost-of-acquisition table (which would otherwise apply) is overridden. Practitioner alert: this is paired with s. 70(1)(c)/(d)/(e) (transactions not regarded as transfer); both the s. 70 tax-neutrality at the transfer event AND the s. 41(2) WDV continuity at the depreciation account must be claimed jointly. Failure of s. 70 condition (e.g., minority introduction within 8 years) cascades back through s. 71.
SUB-SECTIONS (3)-(4) -- DEMERGER WDV SPLIT
Demerger creates a unique WDV-split issue: the demerged company's block-of-assets must be split into demerged-undertaking-WDV (going to resulting co.) and retained-WDV (staying in demerged co.). Sub-s. (3) -- DEMERGED COMPANY: WDV of block in immediately preceding tax year is REDUCED BY the WDV of assets transferred to resulting co. (per demerger). Sub-s. (4) -- RESULTING COMPANY: actual cost of block of assets = WDV of assets transferred from demerged co. immediately before demerger. Practical issue: the WDV split must be calculated by the demerged co. based on the appointed date of demerger; resulting co. inherits exactly what demerged co. transferred. Both sides must align in respective tax computations. Documentation: NCLT order + demerger appointed-date balance sheet + asset-by-asset WDV roll-forward.
SUB-SECTION (5) -- LLP CONVERSION (s. 70(1)(ze))
Where private / unlisted-public company converts to LLP under s. 70(1)(ze) (subject to its 7 conditions), the LLP inherits the company's block-of-assets WDV as on date of conversion (i.e., the actual cost in LLP's hands = WDV in company's hands). Standard tax-neutrality plus WDV continuity. NB: if any of the 7 conditions of s. 70(1)(ze) are breached within 5 years post conversion, s. 71 reverses both the s. 70 transfer-tax-neutrality AND the s. 41(5) WDV continuity, triggering CG charge based on FMV at conversion.
SUB-SECTION (6) -- STOCK EXCHANGE CORPORATISATION
Where assets are transferred to a company under SEBI-approved scheme of corporatisation of a recognised stock exchange (BSE / NSE demutualisation in mid-2000s), WDV continuity is preserved. Largely historical -- demutualisation completed years ago; residual relevance for assets carried forward from member-broker entities into corporatised exchanges.
SUB-SECTION (7) -- SUCCESSION UNDER s. 313
Where assessment is made on successor under s. 313 (succession in business / profession -- like death / retirement / sale-of-business succession), WDV in successor's hands = WDV that would have been taken if assessment had been made directly on the predecessor. Effectively: predecessor's depreciation history transparently flows to successor. Foundational for ensuring no WDV step-up / step-down on succession events not specifically listed elsewhere.
SUB-SECTION (8) -- CARRY-FORWARD DEPRECIATION DEEMED ALLOWED
Any depreciation allowance carried forward under s. 33(11) is DEEMED to be depreciation actually allowed for purposes of s. 41. This ensures that c/f unabsorbed depreciation reduces block-WDV consistently with current-year depreciation -- even though c/f remains a 'tax loss item' set off in subsequent profitable years. Cross-reference: s. 33 (Deduction for depreciation) sub-s. (11) provides the c/f mechanism.
SUB-SECTION (9) -- REVALUATION NEUTRALISATION
Where assessee was NOT REQUIRED to compute total income under this Act (or 1961 Act) for any prior tax year (e.g., trust enjoying full exemption u/s 9 of 1961 Act / now ss. 332-355 of 2025 Act, that subsequently loses exemption; non-resident first time becoming resident; new business outside earlier tax-net), then for first computing WDV: (a) actual cost adjusted by REVALUATION amount in books; (b) book depreciation deemed actually allowed; (c) depreciation actually allowed adjusted for revaluation amount. Effect: prevents revaluation step-up from giving a fresh higher cost-basis when the entity becomes taxable. The book-depreciation-deeming aligns the tax-WDV with the consequence of book-depreciation taken in non-tax years. Inserted post FA 2017 to address charity / trust regime cases. Practitioner: complex calculation; engage with the entity's audited financials covering ALL prior years to extract revaluation transactions and book-depreciation roll-forward.
SUB-SECTION (10) -- PART-AGRICULTURE PART-BUSINESS
For an asset used PARTLY for agriculture (income exempt under Sch. II) and PARTLY for business (PGBP-chargeable), the WDV is computed AS IF the asset were used WHOLLY for business. Effectively: the depreciation would be deemed actually allowed even though the agriculture-portion of the income was exempt. Anti-double-deduction provision: prevents the assessee from claiming full historical-cost WDV (treating agriculture-period as 'no depreciation actually allowed') and thereby double-dipping. Common applicability: tractor / harvester / pump-set used by agriculturist who also runs related business (cold storage / processing); plant in textile mill where part of land is agricultural.
SUB-SECTION (11) -- 'SOLD' DEFINITION
'Sold' for s. 41 = meaning in s. 38(6)(a) -- which (in context of 1961 s. 43(1)/(6)) traditionally includes transfer by way of exchange / compulsory acquisition; excludes mere lease or possession-transfer. Cross-reference imports the technical sale-definition consistently. Industry practice: where doubt arises (e.g., financial lease vs operating lease for asset reclassification), revert to s. 38(6)(a) and underlying contract terms.
INTERACTION WITH SECTION 50 / s. 67 -- BLOCK EMPTYING
When all assets in a block are sold, OR when sale proceeds exceed [(A-D)+B], the block becomes ZERO. The excess sale proceeds become STCG under 1961 s. 50 (now s. 50 of 2025 Act / interaction with s. 67 of CG chapter). This is the 'block emptying' scenario. Importantly, even if the asset sold was held for >36 months, the gain is STCG (the asset's gain has been deemed 'short-term' by virtue of having been depreciated). This LTCG-to-STCG re-character is a 'planning issue' for asset-rich businesses considering full disposal -- LTCG rates are NOT available.
CASE LAW -- LEADING DECISIONS
(i) Whirlpool of India Ltd v. CIT (SC, 2017, 100 taxmann.com 325) -- block-of-assets WDV computation; (A-D)+B-C interpretation. (ii) CIT v. Gujarat Rural Electrification Corporation (Guj HC) -- block-of-assets formula vs prior asset-wise approach. (iii) CIT v. Sundaram Industries Ltd (Mad HC) -- block formula correctly read substantively. (iv) CIT v. Ace Builders Pvt Ltd (Bom HC, 2006, 281 ITR 264) -- depreciable asset sold giving LTCG character; reversed by FA 2003 amendment to 1961 s. 50. (v) CIT v. Centaur Hotels Ltd (Bom HC) -- WDV inheritance through s. 47(iv) [now s. 70(1)(c)] and s. 43(6) Explanation 2A [now s. 41(2)]. (vi) Ardour Spinners v. ACIT (ITAT Chennai) -- demerger WDV split mechanics. (vii) DCIT v. Aravali Polymers LLP (ITAT Kol, 2014) -- LLP conversion conditions and WDV continuity / reversal. (viii) Pavilion Buildings Ltd v. CIT (Cal HC) -- block emptying when last asset sold; STCG character.
PLANNING NOTES (SEVEN AREAS)
(i) BLOCK-WDV ROLL-FORWARD -- maintain accurate prior-year-closing-WDV records; reconcile with tax computation Form 3CD Statement of Particulars; AO scrutiny commonly targets WDV discrepancies. (ii) M&A WDV CONTINUITY -- pair s. 70(1)(c)/(d)/(e) tax-neutrality with s. 41(2) WDV continuity in the transferee's depreciation schedule; document board minutes and asset-register transfer. (iii) DEMERGER WDV SPLIT -- attach asset-by-asset WDV roll-forward to NCLT scheme; verify both demerged-co (sub-s. 3) and resulting-co (sub-s. 4) align. (iv) LLP CONVERSION -- 5-year cure-period for s. 70(1)(ze) -- if PSR / accumulated-profit / turnover-asset conditions breached, both s. 70 and s. 41(5) reverse -- prepare cure-period compliance calendar. (v) BLOCK EMPTYING -- before disposing all assets in a depreciable block, model STCG impact under s. 50 / 67; consider phased disposal or partial reinvestment to prevent block-zero trigger. (vi) AGRICULTURE-MIX (sub-s. 10) -- maintain separate working for asset-mix; AO will deem depreciation actually allowed; prevents double-deduction in subsequent transfer. (vii) REVALUATION (sub-s. 9) -- for entities transitioning from non-tax to tax regime (e.g., trust losing exemption), reconstruct full prior-year revaluation history -- often requires forensic accounting back to inception.
