GST on CSR Expenditure: ITC Block Under Section 17(5)

Can a company claim GST input tax credit on its CSR spending? No. Since 1 October 2023, Section 17(5)(fa) of the CGST Act blocks ITC on all goods and services used for CSR activities under Section 135 of the Companies Act. Vendors still charge GST, but the company cannot recover it. The full GST-inclusive cost is booked as CSR expenditure and counts toward the mandatory 2% spend.

Corporate Social Responsibility sits at the intersection of company law and indirect tax, and the two do not always agree. A company is legally compelled to spend on CSR, yet the GST on that spend cannot be recovered. For a large listed company running a multi-crore CSR programme, that blocked credit runs into tens of lakhs every year. This guide is written for finance controllers, CFOs, and tax teams of companies that fall within Section 135, and for the CAs who sign off their GSTR-3B and Form CSR-2.

We cover the CSR obligation itself, whether vendor invoices carry GST, the precise ITC block introduced by the Finance Act 2023, valuation when you contribute your own goods, the treatment when CSR flows through an implementing agency, the leading AAR positions, and the exact mechanics of recording the reversal.

The CSR obligation under Section 135

Section 135 of the Companies Act 2013 requires a company to constitute a CSR Committee and spend on CSR if, in the immediately preceding financial year, it meets any one of these thresholds:

A company crossing any single threshold must spend at least 2% of the average net profits of the three immediately preceding financial years on activities listed in Schedule VII (education, healthcare, rural development, environmental sustainability, and similar heads). Net profit here is computed under Section 198, not simply the profit before tax in the statement of profit and loss.

The 2% is a floor, not a ceiling. If a company fails to spend the required amount, unspent sums tied to ongoing projects go to a designated Unspent CSR Account within 30 days of year-end, and other unspent amounts go to a Schedule VII fund (such as the PM CARES Fund) within six months. The point that matters for GST: the amount you are obliged to spend is measured on a gross, GST-inclusive basis, because the tax you pay to vendors is part of what leaves the company.

Do CSR vendor invoices carry GST?

Yes, and this is where confusion often starts. The CSR character of a transaction is a matter for the buyer. From the vendor's side, supplying school furniture, constructing a community health centre, or running a skilling programme is an ordinary taxable supply. The vendor raises a tax invoice, charges GST at the applicable rate (5%, 18%, or 40% depending on the item), and deposits it.

Under GST 2.0 the rate slabs are 0%, 5%, 18%, and 40%, following the rationalisation that took effect on 22 September 2025. Most CSR supplies, construction services, consultancy, equipment, sit in the 18% band. So a Rs 50 lakh CSR construction contract carries Rs 9 lakh of GST. The vendor collects it and remits it. The question is entirely whether the company can claim that Rs 9 lakh back as credit. It cannot, and that single fact reshapes how a CSR budget must be built.

The heart of the matter: Section 17(5)(fa) blocks CSR credit

Section 17(5) of the CGST Act lists supplies on which input tax credit is not available, the "blocked credits". The Finance Act 2023 inserted clause (fa) into this list with effect from 1 October 2023. The clause reads, in substance, that ITC shall not be available in respect of goods or services or both used or intended to be used for activities relating to the obligations of Corporate Social Responsibility referred to in Section 135 of the Companies Act 2013.

This is a clean, category-level denial. It does not turn on whether the CSR spend is "in the course or furtherance of business" (the general Section 16 test) or on the "gifts and free samples" logic of Section 17(5)(h). Parliament simply carved CSR out of the credit chain.

The pre-amendment position was genuinely contested

Before 1 October 2023, the law had no CSR-specific clause, and the Authorities for Advance Ruling split:

• The Dwarikesh Sugar Industries ruling (UP AAR) took the view that CSR expenditure is incurred to comply with a statutory obligation and is therefore in the course of business, so ITC should be available and CSR spend is not a "gift" that attracts Section 17(5)(h).
• Other rulings leaned the opposite way, treating CSR distributions as gifts or as not being "used in the course or furtherance of business", and denied the credit.

Because the field was unsettled, many companies took conservative positions and did not claim the credit. The Finance Act 2023 amendment removed the ambiguity prospectively: from 1 October 2023, the answer is a statutory "no" for everyone. Rulings that allowed credit relate to periods before the clause existed and cannot be relied on for current spend.

ITC eligibility scenarios at a glance

Valuation when you contribute your own goods or services

Some companies do not buy from a vendor; they give away what they make. A pharmaceutical company distributing free medicines, or an FMCG company donating its own products, faces a different question: is this a supply, and if so, at what value?

Under Schedule I of the CGST Act, permanent disposal of business assets on which ITC has been availed is treated as a supply even without consideration. Where a supply is deemed and no price is charged, valuation follows Rule 27 to Rule 31 of the CGST Rules, typically the open market value of the goods. In practice, with Section 17(5)(fa) now blocking CSR credit, the sensible route is to not avail credit on inputs that feed CSR give-aways, or to reverse it, so that no downstream tax liability arises on the deemed supply. The embedded, unrecoverable GST on those inputs then forms part of the CSR cost. The net effect mirrors the vendor-purchase case: the company bears the tax and counts it as CSR spend.

CSR through a Section 8 company or registered trust

Larger CSR programmes are commonly executed through an implementing agency: a registered Section 8 company, a registered public trust, or a registered society, often the company's own foundation. Two separate GST questions arise.

First, is the contribution from the company to the agency a "supply"? A pure grant or donation to an implementing agency, made to discharge a CSR obligation with no reciprocal supply to the company, is generally not consideration for a supply and does not attract GST in the company's hands. If, however, the company receives brand promotion or advertising services in return (naming rights, logo display beyond an acknowledgement), the tax authorities may treat that leg as a taxable supply of services by the agency.

Second, what about the agency's own credits? A registered implementing agency that itself procures goods and services and makes taxable outward supplies runs its own credit chain under normal rules. But the Section 17(5)(fa) block bites at the contributing company's level: the company cannot convert a blocked credit into an available one simply by inserting an agency in the middle. For a deeper treatment of how credit gets split and restricted, see our guide on ITC reversal under Rules 42 and 43.

Recording blocked CSR credit in GSTR-3B

There are two acceptable mechanics; pick one and apply it consistently.

Method A (preferred): do not avail. When you book the CSR invoice, record the entire GST-inclusive amount as CSR expenditure and do not populate the ITC in Table 4A of GSTR-3B at all. This is the cleanest audit trail: your books never show the credit, and your GSTR-2B reconciliation notes the invoice as blocked.

Method B: avail and reverse. Some ERPs auto-populate ITC from GSTR-2B. In that case, report the ITC in Table 4A(5) (all other ITC) and reverse the CSR portion in Table 4B(1), the row for credit reversal under Section 17(5). The net credit flowing to your electronic credit ledger is nil for that invoice.

Compliance checklist for CSR GST treatment

1. Tag CSR procurement distinctly in your purchase ledger so blocked invoices are identifiable at filing.
2. Reconcile GSTR-2B each month and flag CSR invoices as ineligible; keep your working papers to explain the reversal. Our note on GSTR-2B reconciliation and ITC eligibility sets out the matching discipline.
3. Book the gross amount (base plus GST) to the CSR expense head; confirm it feeds your 2% computation.
4. Reverse in Table 4B(1) if you availed, or simply do not avail (Method A).
5. Document the position in your tax file, citing Section 17(5)(fa) effective 1 October 2023.
6. File on time. A reversal error or late GSTR-3B can attract interest and late fees; see our GST late fee, interest, and penalty guide for the numbers.
7. Reconcile with Form CSR-2 so the CSR spend disclosed to the MCA matches the gross GST-inclusive figure in your books.

Worked example: a listed company's CSR spend

Facts. Aegis Industries Ltd is a listed company with average net profits (Section 198) of Rs 60 crore over the last three years. Its CSR obligation for FY 2025-26 is 2% of Rs 60 crore.

Step 1: Mandatory CSR spend. 2% of Rs 60,00,00,000 = Rs 1,20,00,000.

Step 2: How the spend is deployed. Aegis executes three projects, all procured from GST-registered vendors:

Step 3: ITC position. Every rupee of the Rs 15,65,000 GST is blocked under Section 17(5)(fa). None of it reaches the electronic credit ledger. If Aegis's ERP auto-populated the credit, the full Rs 15,65,000 is reversed in Table 4B(1) of GSTR-3B.

Step 4: CSR spend recognised. Because the tax is unrecoverable, the CSR expenditure is the full invoice value of Rs 1,20,65,000, which comfortably discharges the Rs 1,20,00,000 obligation. The GST of Rs 15,65,000 is not a separate outflow to be recovered later; it is embedded cost.

The takeaway from the numbers: the blocked credit costs Aegis Rs 15,65,000 in real, unrecoverable tax on a single year's programme. Over a five-year CSR horizon at similar scale, that is nearly Rs 80 lakh of tax that never comes back. Knowing the credit is blocked lets the finance team budget the gross figure up front rather than discovering a shortfall at year-end.

Why the block exists, and where it surfaces in the annual return

The policy logic is worth understanding, because it guides how you defend the position in assessment. Input tax credit is meant to relieve tax on inputs that feed a taxable output, keeping the tax on value addition rather than on the chain. CSR spend produces no taxable output for the company; it discharges a statutory welfare obligation. Allowing credit would let the exchequer effectively fund a slice of every company's CSR programme. Parliament closed that door with clause (fa) rather than leaving it to the general "course or furtherance of business" test, which litigants had stretched both ways.

At year-end, the reversal you made month by month must reconcile in the annual return. In GSTR-9, the ITC reversed under Section 17(5) is reported in Table 7, and the figure should tie back to the sum of your Table 4B(1) reversals across the twelve GSTR-3B filings. If you used Method A and never availed the credit, there is nothing to reverse in GSTR-9 either, but keep the GSTR-2B trail showing why those CSR invoices were treated as ineligible. A mismatch between the credit blocked in the annual return and the CSR spend disclosed in Form CSR-2 is exactly the kind of inconsistency that draws a departmental query, so reconcile the two before you file.

Common mistakes to stay clear of

• Claiming the credit and hoping it survives audit. The clause is unambiguous from 1 October 2023. A wrongful claim invites reversal with interest.
• Budgeting CSR on a net-of-GST basis. If you plan to spend exactly Rs 1.2 crore but forget the tax is your cost, you may fall short of the statutory 2% or overshoot the budget.
• Mixing genuine business inputs into the CSR bucket. Not every socially-flavoured spend is Section 135 CSR. Marketing sponsorships with a business return are ordinary inputs; do not needlessly forfeit that credit.
• Ignoring the deemed-supply angle on own goods. If you gave away self-manufactured products and had availed input credit, address the reversal or open-market-value liability rather than leaving it open.

CSR is one of the clearest examples of GST law deliberately breaking the credit chain to prevent the exchequer from subsidising a company's statutory obligation. Once the finance team internalises that the tax is a sunk cost, the compliance itself is straightforward: book gross, reverse or do not avail, and reconcile to Form CSR-2.
