ITC on CSR expenditure: Section 17(5)(fa) statutory amendment explained

Every year, when our team examines corporate inward supply registers between the 14th and the 20th, we encounter hundreds of vendor invoices relating to community initiatives. Large corporations and mid-sized companies meeting statutory net worth or profit thresholds routinely incur substantial expenditure on community projects, healthcare facilities, rural schools, and environmental programs. These inward vendor supplies carry GST, appear in auto-generated GSTR-2B statements, and prompt accounting teams to evaluate credit eligibility. In our practice reviewing company returns, businesses frequently relied on conflicting advance rulings to claim credit by arguing that mandatory CSR was incurred in the furtherance of business. The Finance Act 2023 eliminated this ambiguity by inserting clause (fa) into Section 17(5). Understanding the boundaries of this statutory bar prevents audit disallowances, interest liabilities under Section 50, and automated scrutiny notices.

The statutory bar: Section 17(5)(fa) of the CGST Act

Under Section 16(1) of the CGST Act, a registered taxable person enjoys a broad entitlement to claim credit of input tax charged on supplies used or intended to be used in the course or furtherance of business. However, Section 17(5) overrides this general entitlement through an explicit non-obstante clause:

“Notwithstanding anything contained in sub-section (1) of section 16 and sub-section (1) of section 18, input tax credit shall not be available in respect of the following, namely:-” Section 17(5), CGST Act

Section 139 of the Finance Act 2023 inserted clause (fa) into Section 17(5). By virtue of Notification No. 28/2023-Central Tax, the Central Government appointed 1 October 2023 as the effective implementation date. The statutory provision reads:

“(fa) goods or services or both received by a taxable person, which are used or intended to be used for activities relating to his obligations under corporate social responsibility referred to in section 135 of the Companies Act, 2013;” Section 17(5)(fa), CGST Act

The wording leaves no room for subjective interpretation. Any inward supply received by a company that relates to discharging its Corporate Social Responsibility mandate under corporate law is disqualified from input tax credit. For a full breakdown of all blocked heads under the law, consult our detailed reference on blocked credit under GST Section 17(5).

Interaction with Section 135 of the Companies Act 2013

The restriction in Section 17(5)(fa) directly hinges on the statutory mandate codified under corporate law. Under Section 135 of the Companies Act 2013, every company having a net worth of ₹500 crore or more, turnover of ₹1,000 crore or more, or a net profit of ₹5 crore or more during the immediately preceding financial year must constitute a Corporate Social Responsibility Committee and spend at least 2 percent of its average net profits on approved activities listed in Schedule VII.

Key operational aspects of Section 135 read with the Companies (Corporate Social Responsibility Policy) Rules 2014 include:

1. Mandatory statutory spend: Qualifying corporate entities must spend at least 2 percent of average net profits made during the three immediately preceding financial years on Schedule VII initiatives such as healthcare, education, environmental sustainability, and rural infrastructure.
2. Exclusion of normal business activities: Under Rule 2(1)(d) of the CSR Rules 2014, activities undertaken in pursuance of normal course of business do not qualify as CSR. Corporate law treats CSR as separate from commercial trade.
3. Direct procurement versus implementing agencies: Whether a corporate enterprise purchases medical equipment directly to donate to a rural hospital, or contracts with a registered third-party project management entity to construct school classrooms, all inward invoices tied to fulfilling the annual CSR target fall under the Section 17(5)(fa) bar.

Pre-amendment judicial landscape versus the statutory bar

Prior to the Finance Act 2023, the absence of an express statutory clause addressing CSR generated substantial tax litigation. Taxpayers argued that failing to comply with Section 135 of the Companies Act attracted penal consequences, disqualification of directors, and reputational injury. Consequently, complying with Section 135 was an essential requirement to run a corporate enterprise, falling squarely within the phrase “in the course or furtherance of business” under Section 16(1).

State Advance Ruling authorities issued contradictory pronouncements, creating confusion across corporate circles:

• Pro-taxpayer positions: The Uttar Pradesh AAR in Dwarikesh Sugar Industries Limited held that mandatory CSR activities under Section 135 were non-negotiable legal duties without which a company could not maintain corporate existence. The Authority ruled that inward supplies for CSR were incurred in furtherance of business, permitting input tax credit. Similar positive views existed in earlier service tax decisions by CESTAT benches.
• Pro-revenue positions: Conversely, the Telangana Authority for Advance Ruling in Bambino Agro Industries Limited held that CSR activities were philanthropic donations without commercial consideration, effectively falling under blocked categories such as gifts under Section 17(5)(h). The Kerala AAR in Polycab Wires Private Limited similarly rejected credit on flood relief supplies distributed under CSR obligations.

The insertion of Section 17(5)(fa) statutorily superseded this conflicting jurisprudence from 1 October 2023. For periods following this date, no reliance can be placed on favorable advance rulings or tribunal precedents. For inward invoices issued on or after 1 October 2023, the statutory bar is absolute.

Distinguishing CSR from commercial brand promotion and sponsorships

A frequent area of confusion in corporate accounting is separating statutory CSR outlays from purely commercial marketing and brand sponsorships. The GST law restricts credit solely on activities relating to obligations under Section 135 of the Companies Act. It does not disallow ordinary business development, commercial sponsorships, or marketing expenditures.

To preserve legitimate business credits while properly isolating blocked CSR tax, accountants should establish distinct cost centres in ERP systems such as SAP, Tally Prime, or Zoho Books. If an expense is booked against the statutory CSR allocation to satisfy Board-approved targets under Section 135, its GST component must be flagged as ineligible. Conversely, if an expenditure represents a commercial sponsorship where the company receives contractual publicity, promotional rights, or commercial signage, the transaction remains an eligible business expense under Section 16(1).

Step-by-step reporting in Form GSTR-3B: Table 4(B)(1) permanent reversal

Under CBIC Circular No. 170/02/2022-GST, taxpayers must adhere to standard reporting protocols to reflect inward supplies and ineligible credits transparently. The GST portal does not know whether a specific vendor invoice relates to commercial operations or a Section 135 CSR project. Therefore, the filing entity must execute manual classification and reversal.

1. Step 1: Receipt and GSTR-2B reflection: Your vendor or contractor issues a tax invoice bearing your corporate GSTIN. Once filed in their GSTR-1 or Invoice Furnishing Facility, the invoice details appear in your GSTR-2B statement. On the common portal, this tax auto-populates inside Table 4(A)(5) (“All other ITC”) of Form GSTR-3B. For portal operations, see the GSTN GSTR-3B user manual.
2. Step 2: Segregation of CSR line items: During monthly reconciliation, extract all inward invoices tagged to CSR job codes or project cost centres. Sum the integrated tax, central tax, and state tax components.
3. Step 3: Permanent reversal in Table 4(B)(1): Because Section 17(5)(fa) is a statutory block, this tax credit is permanent and non-reclaimable. Never declare this reversal in Table 4(B)(2) (which is reserved for temporary reversals that can be re-availed in the future, such as 180-day vendor payment defaults under Rule 37). Enter the full ineligible amount in Table 4(B)(1) (“As per rules 38, 42 and 43 of CGST Rules and section 17(5)”).
4. Step 4: Net credit auto-computation in Table 4(C): The portal calculates Net ITC Available in Table 4(C) using the statutory formula [Table 4(A) minus Table 4(B)]. The ineligible CSR amount is removed from the electronic credit ledger credit balance.

Worked corporate rupee calculation: annual CSR procurement

Consider Zenith Engineering Limited, a manufacturing enterprise in Pune, Maharashtra. During Financial Year 2025-26, the company calculates its statutory Section 135 CSR obligation as ₹60,00,000 based on 2 percent of its average net profits. In October 2026, the company undertakes three major community development and promotional initiatives:

• Project A (Rural Health Center): Purchase of diagnostic medical equipment donated to a primary health centre under its approved CSR mandate. Taxable value: ₹30,00,000 plus 18 percent IGST of ₹5,40,000. Total invoice: ₹35,40,000.
• Project B (School Building Renovation): Contracting a registered civil firm to renovate rural government schools under its approved CSR mandate. Taxable value: ₹20,00,000 plus 18 percent IGST of ₹3,60,000. Total invoice: ₹23,60,000.
• Project C (State Marathon Commercial Sponsorship): Sponsoring a regional marathon with extensive corporate branding, media backdrops, and product exhibition stalls handled by a sports event agency. Taxable value: ₹10,00,000 plus 18 percent IGST of ₹1,80,000. Total invoice: ₹11,80,000.

The company prepares its Form GSTR-3B for October 2026 before the 20 November 2026 deadline:

1. The entire gross IGST of ₹10,80,000 auto-populates from GSTR-2B into Table 4(A)(5).
2. The finance team determines total blocked CSR tax: ₹5,40,000 (medical equipment) + ₹3,60,000 (school works) = ₹9,00,000.
3. The team enters ₹9,00,000 in Table 4(B)(1) as ineligible credit under Section 17(5).
4. Table 4(C) computes Net ITC Available: ₹10,80,000 minus ₹9,00,000 = ₹1,80,000, which is credited to the electronic credit ledger for the eligible commercial sponsorship.

By correctly declaring ₹9,00,000 in Table 4(B)(1), Zenith Engineering avoids wrongful credit availment, eliminates interest risks under Section 50(3), and satisfies corporate tax reporting guidelines.

Audit defence and accounting controls

During GST audits and departmental scrutiny under Section 61, tax officers cross-reference the CSR expenditure reported in your audited financial statements (under Note on Other Expenses in accordance with Schedule III of the Companies Act) with Table 4(B)(1) of Form GSTR-3B and Table 7 of Form GSTR-9. If the financial statements show ₹50,00,000 spent on CSR but the annual return shows zero reversals under Section 17(5), an audit objection is issued automatically.

To defend company filings and ensure internal compliance:

1. Maintain separate ledger accounts: Create an independent ledger in your chart of accounts titled “CSR Expenses (GST Ineligible)”. Do not mix CSR vendor bills with general factory maintenance, office repairs, or brand advertising.
2. Reconcile books with return disclosures: Ensure the cumulative tax debited to expense from CSR vendor bills matches the cumulative reversals reported in Table 4(B)(1) across the twelve monthly GSTR-3B returns.
3. Archive contractual documentation for sponsorships: For all promotional marketing and commercial sponsorships, maintain agreements, media plans, and photographs demonstrating corporate brand visibility to disprove allegations of unlisted CSR or gift distributions under Section 17(5)(h).
