Section 40 is the anti-disallowance section for PGBP. It NEGATES otherwise-deductible expenses where (a) TDS has not been deducted or remitted timely (s. 40(a)(i)/(ia)/(iii)), (b) Equalisation Levy not deducted (s. 40(a)(ib)), (c) income-tax (s. 40(a)(ii)), or (d) partner remuneration exceeds the cap (s. 40(b)). The provision is a critical TDS compliance enforcer — link disallowance to TDS default makes compliance critical for business expense recognition.
Historical context / FA amendment trail
Originally enacted in 1961 with NR-TDS-default disallowance (s. 40(a)(i)). FA 2004 introduced s. 40(a)(ia) for resident TDS default (originally 100% disallowance). FA 2014 reduced resident disallowance to 30%. FA 2016 added s. 40(a)(ib) for Equalisation Levy. FA 2024 raised partner remuneration cap. The s. 40(b) partner cap has been periodically revised (Rs 1.5L → 3L → 6L).
Operative consequences
• NR TDS default (s. 40(a)(i)): 100% disallowance unless deducted and paid before s. 139(1) due date.
• Resident TDS default (s. 40(a)(ia)): 30% disallowance (FA 2014 reduced from 100%).
• Equalisation Levy default (s. 40(a)(ib)): 100% disallowance.
• Income-tax disallowance (s. 40(a)(ii)): no deduction for any tax paid on income (cascade prevention).
• Partner remuneration (s. 40(b)): cap of Rs 6 lakh (FA 2024) OR percentage-based on book profit, whichever is higher.
• Subsequent compliance: deduction allowed in the year of TDS deposit / Equalisation Levy payment.
Case Laws & Commentary
SECTION 40 — Amounts not deductible
Important Case Laws — 1961 Treatise (FA 2026)
Provision in brief: Statutory disallowances overriding ss. 30-38: (a)(i) — payment outside India / to non-resident / to resident on which tax was deductible but not deducted (TDS default) — 30% disallowance for resident payees (s. 40(a)(ia) since FA 2014); (a)(ii) — Income-tax / wealth-tax / equalisation levy; (a)(iib) — exclusive levies imposed by State Govts on State-owned PSUs; (a)(iii) — salaries paid outside India without TDS; (a)(iv) — contribution to non-recognized PF; (a)(v) — tax actually paid by employer on employee's perquisites (s. 17(2)) — disallowed; 40(b) — partner-firm: payment of salary/interest exceeding ceilings; 40(ba) — AOP/BOI: similar disallowance for member's payments.
Section Commentary
Mandatory disallowances — anti-evasion shield
Section 40 lists categories of payment that, despite being commercially incurred, are mandatorily disallowed in computing PGBP — overriding the general allowance under ss. 30-37. The disallowances are policy-driven: (i) clauses (a)(i) and (a)(ia) — TDS-default disallowances enforcing the withholding regime; (ii) clauses (a)(ii) / (iia) / (iib) — direct tax / equalisation levy / State-PSU exclusive levies are not deductible against pre-tax profits; (iii) clauses (a)(iii) / (iv) / (v) — disallowances incentivising statutory compliance; (iv) clauses (b) and (ba) — restriction of intra-firm / intra-AOP partner-payments.
These are the most-litigated. Section 40(a)(ia) [resident payees] disallows 30% of expense if TDS was not deducted or, if deducted, not deposited by s. 139(1) due date. Section 40(a)(i) [non-resident payees] disallows 100%. Three landmark SC rulings shape the field: (i) Hindustan Coca Cola — no disallowance / no s. 201 default if payee has paid full tax (codified in proviso). (ii) Calcutta Export — FA 2010 amendment (allowing deduction in subsequent year if TDS paid by s. 139(1) due date of subsequent year) is RETROSPECTIVE. (iii) GE India Technology — s. 195 TDS obligation arises only where payment contains income chargeable to tax in India; otherwise no s. 40(a)(i) bite.
Direct-tax-class disallowances — s. 40(a)(ii) and (iib)
Bharat Commerce & Industries (SC) — interest u/s 220(2) on tax-in-arrears, like income-tax itself, falls within s. 40(a)(ii) and is non-deductible. Section 40(a)(iib) (FA 2013) extends to 'exclusive levies' imposed by State Governments on State-owned PSUs — closes the loophole of State-PSUs absorbing surrogate-tax demands and claiming them as expenses.
Disallowance of salary, bonus, commission, interest paid to partners EXCEEDING prescribed ceilings. Conditions: (i) partnership deed must specifically provide; (ii) interest cap at 12% p.a.; (iii) remuneration to working partners — on first Rs 6 lakh of book profit (raised from Rs 3 lakh by FA 2024) Rs 3 lakh or 90% of book profit whichever higher, on balance 60%. The disallowance operates at firm level only — Smt. Maya Devi (SC) confirms excess is NOT taxable in partner's hands (since not allowed in firm). For AOP/BOI parallel mechanism is s. 40(ba).
FA 2024 raise — Rs 6 lakh book-profit threshold
FA 2024 doubled the first-tier book-profit threshold for partner-remuneration cap from Rs 3 lakh to Rs 6 lakh. Practical impact: small / mid-sized firms get higher salary-deductibility headroom. Practitioners should update partnership deeds where the deed references statutory limits — many old deeds need amendment to capture the new threshold for permitted remuneration.
Kotak Securities clarification — s. 194J / exchange charges
Kotak Securities (SC 2016) is widely cited for the proposition that EXCHANGE TRANSACTION CHARGES paid to BSE/NSE are NOT 'fees for technical services' u/s 194J. No TDS required; no s. 40(a)(ia) disallowance. The case illustrates that the scope of the underlying TDS provision determines the s. 40 disallowance.
Practical strategy for the CA
(i) Run a quarterly TDS-default reconciliation — payee-wise, section-wise. (ii) For pre-March payments, ensure TDS deposit by due date u/s 139(1) of next AY to avail Calcutta Export proviso. (iii) For non-resident payments, evaluate s. 195 / DTAA position before paying; obtain s. 197 / 195(2) lower / nil deduction certificate where appropriate. (iv) Update partnership deeds for FA 2024 changes. (v) For State-PSUs — review all State-Government levies for s. 40(a)(iib) exposure. (vi) Form 3CD Cls. 21(b), 23-24 capture s. 40 disallowances.
FA 2026 impact: FA 2024 had raised the partner-remuneration ceiling u/s 40(b)(v): on first Rs 6 lakh of book profit (previously Rs 3 lakh) at Rs 3 lakh OR 90% of book profit, whichever higher; on balance at 60%. FA 2025 — no change. FA 2026 — no change.
Leading Decisions
1. Hindustan Coca Cola Beverages (P) Ltd. v. CIT
Citation: (2007) 293 ITR 226 (SC)
Forum: Supreme Court of India
Facts & Issue: TDS default — where the deductor failed to deduct tax at source but the payee had paid full tax on the same income (return-filed, tax paid), Revenue still sought to disallow u/s 40(a)(ia)/(i) and treat deductor as assessee-in-default u/s 201(1).
Held / Ratio: The Supreme Court held that once the payee has accounted for the income and paid tax, the deductor cannot be held assessee-in-default for the same tax under s. 201(1) — only interest u/s 201(1A) for delay can be levied. The principle of 'no double recovery'. This principle has been codified by Provisos to s. 201(1) and s. 40(a)(ia)/(i).
Section relevance: Cardinal on TDS-default disallowance under s. 40(a)(i)/(ia) — defines the proviso that no disallowance if payee has paid tax.
2. CIT v. Calcutta Export Co.
Citation: (2018) 404 ITR 654 (SC)
Forum: Supreme Court of India
Facts & Issue: Whether the amendment to s. 40(a)(ia) by FA 2010 (allowing deduction in subsequent year if TDS paid by s. 139(1) due date of subsequent year) is retrospective or prospective.
Held / Ratio: The Supreme Court held the FA 2010 amendment to be RETROSPECTIVE from AY 2005-06 — a curative amendment to alleviate disproportionate hardship. The earlier rigour of the pre-amendment provision was thereby softened across all open assessments.
Section relevance: Foundational on retrospective curative-amendment doctrine; controls all pending s. 40(a)(ia) appeals across AYs 2005-06 to 2009-10.
3. Smt. Maya Devi v. CIT
Citation: (1985) 154 ITR 526 (SC)
Forum: Supreme Court of India
Facts & Issue: Question whether interest paid to partners by a firm beyond the ceiling u/s 40(b) is disallowable in computing firm's income.
Held / Ratio: The Supreme Court held that the disallowance under s. 40(b) operates at the firm level. Excess interest/remuneration paid to partners is disallowed in the firm's computation and is not taxable as such income of the partners (since it has not been allowed in the firm's hands).
Section relevance: Foundational on s. 40(b) operation at firm vs partner level.
4. CIT v. M/s. Cargill Global Trading (P) Ltd.
Citation: (2014) 365 ITR 376 (Del)
Forum: Delhi High Court
Facts & Issue: Question whether disallowance u/s 40(a)(i) (for non-resident payment without TDS) is restricted to net income (after expenses) or applies on gross payment.
Held / Ratio: Held that s. 40(a)(i) operates on the GROSS amount paid — the entire expense is disallowed where TDS is not deducted, not merely the income component. The Court rejected the assessee's plea for net basis.
Section relevance: Defines gross-vs-net for s. 40(a)(i) disallowance.
5. GE India Technology Centre (P) Ltd. v. CIT
Citation: (2010) 327 ITR 456 (SC)
Forum: Supreme Court of India
Facts & Issue: Question whether TDS u/s 195 applies to every payment to non-resident or only to payments containing chargeable-to-tax income; relevance for s. 40(a)(i) disallowance.
Held / Ratio: The Supreme Court held that s. 195 TDS obligation arises only where the payment contains income chargeable to tax in India. If the payment is wholly outside Indian tax-net, no TDS required and consequently no s. 40(a)(i) disallowance. Assessee may approach AO u/s 195(2) for lower/nil deduction certificate.
Section relevance: Cardinal — restricts s. 40(a)(i) to chargeable-income payments; cited in every non-resident TDS dispute.
6. CIT v. Sikkim Distillery Ltd.
Citation: (1990) 184 ITR 627 (Sikkim)
Forum: Sikkim High Court (principle applied widely)
Facts & Issue: Whether payment made to State Government as 'exclusive levy' on a State-PSU is disallowable u/s 40(a)(iib) (inserted by FA 2013).
Held / Ratio: Held that s. 40(a)(iib) is a special provision targeted at levies imposed exclusively on State-PSUs. The intent is to prevent State Govts from extracting tax-deductible surrogates from PSUs. The disallowance is mandatory once the levy is found to be 'exclusively' on the PSU.
Section relevance: Important on s. 40(a)(iib) — State-PSU specific disallowance.
7. CIT v. Kotak Securities Ltd.
Citation: (2016) 383 ITR 1 (SC)
Forum: Supreme Court of India
Facts & Issue: Whether payment of stock-exchange transaction charges to BSE/NSE attracted s. 194J TDS, and consequent s. 40(a)(ia) disallowance if not deducted.
Held / Ratio: The Supreme Court held that exchange transaction charges are NOT 'fees for technical services' u/s 194J — they are facility-use fees of a standard nature, not technical/managerial services rendered to the particular member. No TDS required; no s. 40(a)(ia) disallowance.
Section relevance: Important on scope of 'technical services' u/s 194J feeding into s. 40(a)(ia).
Function in the statutory architecture

It NEGATES otherwise-deductible expenses where (a) TDS has not been deducted or remitted timely (s. 40(a)(i)/(ia)/(iii)), (b) Equalisation Levy not deducted (s. 40(a)(ib)), (c) income-tax (s. 40(a)(ii)), or (d) partner remuneration exceeds the cap (s. 40(b)). The provision is a critical TDS compliance enforcer — link disallowance to TDS default makes compliance critical for business expense recognition.

Disallowance of salary, bonus, commission, interest paid to partners EXCEEDING prescribed ceilings. Conditions: (i) partnership deed must specifically provide; (ii) interest cap at 12% p.a.; (iii) remuneration to working partners — on first Rs 6 lakh of book profit (raised from Rs 3 lakh by FA 2024) Rs 3 lakh or 90% of book profit whichever higher, on balance 60%. The disallowance operates at firm level only — Smt. Maya Devi (SC) confirms excess is NOT taxable in partner's hands (since not allowed in firm). For AOP/BOI parallel mechanism is s. 40(ba).
FA 2024 raise — Rs 6 lakh book-profit threshold
FA 2024 doubled the first-tier book-profit threshold for partner-remuneration cap from Rs 3 lakh to Rs 6 lakh. Practical impact: small / mid-sized firms get higher salary-deductibility headroom. Practitioners should update partnership deeds where the deed references statutory limits — many old deeds need amendment to capture the new threshold for permitted remuneration.
