Introduction
Input Tax Credit (“ITC”) is the backbone of GST. It prevents cascading of taxes and allows a registered person to set off tax paid on inward supplies against output tax liability. However, ITC is not an absolute right. It is a statutory benefit available only when the conditions, restrictions and procedures prescribed under the GST law are satisfied.
The legal scheme of ITC under the CGST Act, 2017 is layered. Section 16 creates the basic entitlement. Section 17 restricts or blocks credit. Section 18 grants credit in special circumstances. Rules 36, 37, 37A, 40, 42 and 43 regulate availment, reversal, re-availment and apportionment. Section 50 and Rule 88B deal with interest where ITC is wrongly availed and utilised. GSTN advisories and return utilities further require correct reporting in GSTR-3B, especially in Table 4.
Therefore, the question is not merely whether an expense is business-related. The real question is whether the ITC passes through section 16, survives section 17, complies with the rules and is correctly reported in GST returns.
1. Section 16: The first gate for ITC
Section 16(1) permits a registered person to take credit of input tax charged on goods or services or both used or intended to be used in the course or furtherance of business. But this entitlement is subject to conditions and restrictions.
Section 16(2) requires possession of invoice or prescribed document, receipt of goods or services, payment of tax to Government and furnishing of return. Section 16(4) further prescribes the time limit for availment. The uploaded GST material discusses that section 16(1) is an enabling provision, while section 16(2) and section 16(4) operate as mandatory statutory conditions.
The legal principle is also supported by decisions such as ALD Automotive Pvt. Ltd. v. Assistant Commissioner and TVS Motor Company v. State of Tamil Nadu, where courts have treated ITC as a statutory concession subject to conditions. Recent GST litigation has also examined the mandatory nature of section 16 conditions and the consequences of non-compliance.
Thus, if section 16 itself is not satisfied, credit is not available at the threshold.
2. If section 16(1) is complied with, why can ITC still be blocked?
This is the core issue in blocked credit litigation.
A taxpayer may argue that the inward supply is used in the course or furtherance of business and therefore ITC must be available. However, section 16(1) itself is subject to restrictions. Further, section 17(5) begins with a non-obstante clause: “notwithstanding anything contained in sub-section (1) of section 16 and sub-section (1) of section 18.”
This means section 17(5) overrides the general entitlement under section 16(1). Therefore, even if an inward supply is used for business, credit may still be blocked if it falls within section 17(5).
For example, GST paid on construction of an office building, food and beverages, employee vacation travel, gifts or certain motor vehicles may be business expenditure in books of accounts. Yet ITC may be blocked because the legislature has specifically denied it under section 17(5).
In simple terms:
Section 16 answers: Is ITC generally eligible?
Section 17(5) answers: Even if eligible, is it specifically blocked?
3. Section 17(1), 17(2), Rule 42 and Rule 43: Apportionment is not the same as blocked ITC
Section 17(1) restricts ITC where goods or services are used partly for business and partly for non-business purposes. Section 17(2) restricts ITC where goods or services are used partly for taxable/zero-rated supplies and partly for exempt supplies.
Rule 42 provides the mechanism for reversal of common credit relating to inputs and input services. Rule 43 applies to capital goods. Departmental audit objections commonly invoke Rule 42 where common ITC is availed despite exempt supplies.
This is different from blocked ITC. Rule 42/43 reversal is proportionate reversal. Section 17(5) is a statutory bar.
4. Main categories of blocked ITC under section 17(5)
4.1 Motor vehicles
ITC on motor vehicles for transportation of persons having approved seating capacity of not more than 13 persons, including the driver, is blocked, except where used for specified purposes such as further supply of such vehicles, transportation of passengers or imparting training on driving.
Motor vehicles used for transportation of goods are not blocked merely on this ground. Audit objections often identify ITC on motor vehicles, parts and construction materials as blocked under section 17(5).
Section 17(5)(aa): Vessels and aircraft
The logic of clause (aa) is similar to motor vehicles, but the exception is broader in one important sense: vessels and aircraft may also qualify where used for transportation of goods.
Therefore, the important question is not ownership or capitalisation, but the functional deployment of the vessel or aircraft.
The official text of section 17(5)(aa) permits ITC where vessels or aircraft are used for further supply, passenger transportation, training in navigation/flying, or transportation of goods
Section 17(5)(ab): Insurance, servicing, repair and maintenance of motor vehicles, vessels and aircraft
Clause (ab) is a derivative restriction. The eligibility of repair, servicing, maintenance and insurance follows the eligibility of the underlying vehicle, vessel or aircraft.
If ITC on the vehicle itself is blocked, ITC on insurance or repairs will generally also be blocked. If the vehicle is eligible because it is used for permitted taxable supplies, related insurance/repair credit may also become eligible.
Circular No. 231/25/2024-GST dated 10.09.2024 — ITC on demo vehicles
CBIC clarified that demo vehicles are maintained by authorised dealers as per dealership norms for trial runs and demonstration to potential buyers; they are purchased against tax invoices and are often capitalised in the books of account.
The circular explains that section 17(5)(a) does not block ITC where such motor vehicles are used for making taxable supplies of further supply of such motor vehicles, transportation of passengers or imparting training on driving such vehicles.
CBIC further clarified that demo vehicles promote sale of similar motor vehicles and can be considered as used by the dealer for making “further supply of such motor vehicles”; accordingly, ITC on such demo vehicles is not blocked under section 17(5)(a). However, where vehicles are used for staff/management transportation, or where the dealer merely provides marketing/facilitation services and is not making supply of vehicles on his own account, ITC is not excluded from blockage and would not be available.
The circular also clarifies that capitalisation of demo vehicles in books does not itself defeat ITC, because capital goods are also goods used or intended to be used in the course or furtherance of business. However, section 16(3) must be respected: if depreciation is claimed on the tax component under the Income-tax Act, ITC on that tax component is not allowed. On subsequent sale of capitalised demo vehicles, section 18(6) read with Rule 44(6) may apply.
4.2 Food, beverages, outdoor catering, health services and insurance
Section 17(5)(b) blocks ITC on food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery, leasing/renting/hiring of motor vehicles, vessels and aircraft, life insurance and health insurance, subject to exceptions.
This clause is often wrongly applied mechanically. The law itself contains two saving windows:
1. Same-category outward taxable supply; or
2. Part of taxable composite or mixed supply.
Further, the proviso to section 17(5)(b) allows ITC where it is obligatory for an employer to provide such goods or services to employees under any law.
Circular No. 172/04/2022-GST clarified that the proviso applies to the whole of section 17(5)(b), not merely to travel benefits. Therefore, statutory canteen, mandatory insurance or legally required employee welfare facilities may not be automatically blocked.
4.3 Club membership, health and fitness centres
ITC on membership of clubs, health and fitness centres is blocked. Business accounting treatment alone cannot override the statutory bar.
This clause has almost no business-purpose escape. Even if the membership is used for client meetings, networking or employee wellness, ITC may still be blocked unless it is part of a taxable outward supply structure.
This clause is a classic example where section 16(1) business use is overridden by section 17(5).
4.4 Travel benefits to employees
ITC on travel benefits extended to employees on vacation, such as leave or home travel concession, is blocked unless covered by a statutory obligation exception.
The word “vacation” is important. Ordinary business travel is not the target of this clause. What is blocked is travel benefit extended to employees on vacation, such as leave travel concession or home travel concession.
Therefore, one must not confuse:
Business travel for official work = generally test under section 16
Vacation travel benefit / LTC / HTC = section 17(5)(b)(iii) blockage
“Circular No. 172/04/2022-GST dated 06.07.2022 is a significant clarification on employee-related blocked credits. CBIC has clarified that the proviso to section 17(5)(b), which allows ITC where it is obligatory for an employer to provide goods or services to employees under any law, applies to the entire clause (b) and not merely to travel benefits under sub-clause (iii). Therefore, in cases such as statutory canteen facility, mandatory employee insurance or other legally required employee welfare facilities, ITC may not be blocked merely because the supply falls within section 17(5)(b), subject to proper factual verification and documentation.”
4.5 Works contract and construction of immovable property
Section 17(5)(c) blocks ITC on works contract services supplied for construction of immovable property, other than plant and machinery, except where it is an input service for further supply of works contract service.
Section 17(5)(d) blocks ITC on goods or services or both received for construction of immovable property, other than plant or machinery, on own account, even when used in the course or furtherance of business.
The Supreme Court decision in Chief Commissioner of CGST v. Safari Retreats Pvt. Ltd. is important for interpreting “plant or machinery” and the functionality test.
Circular No. 219/13/2024-GST dated 26.06.2024 — ITC on ducts and manholes used in OFC network
This circular deals with section 17(5)(c) and section 17(5)(d), especially the distinction between immovable property and plant and machinery.
CBIC clarified that representations were received because ITC on ducts and manholes used in optical fibre cable networks was being denied on the ground that such items were immovable property other than plant and machinery.
The circular explains that section 17(5)(c) blocks works contract services for construction of immovable property other than plant and machinery, and section 17(5)(d) blocks goods or services used for construction of immovable property other than plant or machinery on own account. It also refers to the explanation to section 17 defining “plant and machinery”.
CBIC clarified that ducts and manholes are basic components of the OFC network used for providing telecommunication services and are covered under “plant and machinery”; they are not specifically excluded as land, building, civil structures, telecommunication towers or pipelines laid outside factory premises. Accordingly, ITC is not restricted under section 17(5)(c) or 17(5)(d) in respect of such ducts and manholes used in OFC networks.
Practical principle:
For section 17(5)(c)/(d), the test is not merely whether something is fixed to earth. The correct test is whether the item falls within the statutory meaning of plant and machinery and whether it is specifically excluded.
4.6 Section 17(5)(e): Goods or services on which tax is paid under composition levy
This is not ordinary blocked credit. It is a structural denial because composition tax is not “input tax” in the credit chain in the same manner as normal GST.
A recipient cannot take ITC because a composition supplier does not charge tax in the manner of a regular taxable invoice.
The official text specifically blocks goods or services on which tax has been paid under section 10.
4.7 Section 17(5)(f): Non-resident taxable person
A non-resident taxable person is denied ITC except on goods imported by him. This reflects the temporary/event-based nature of non-resident registration.
The focus is not business use, but status of the recipient.
The official text states that goods or services received by a non-resident taxable person are blocked, except on goods imported by him.
4.8 Section 17(5)(fa): CSR expenditure
CSR credit was controversial earlier because CSR is a statutory obligation under section 135 of the Companies Act, 2013. The legislature later inserted a specific blockage for goods or services used or intended to be used for CSR obligations.
Therefore, after insertion of clause (fa), the argument that CSR is “in the course or furtherance of business” becomes insufficient.
The official text now blocks goods or services used or intended to be used for activities relating to CSR obligations under section 135 of the Companies Act, 2013.
Before clause (fa), there were competing rulings on CSR credit. After insertion, the statutory bar is specific. Therefore, for current law, litigation must focus on whether the activity is truly CSR under section 135, not merely whether it benefits the business.
4.9 Section 17(5)(g): Personal consumption
This clause is fact-heavy. The same inward supply may be eligible or blocked depending on the end-use.
For example:
Hotel stay for business travel = may be eligible, subject to other provisions.
Hotel stay for personal holiday = blocked.
Director’s personal facility = blocked.
Employee facility mandated by law = examine section 17(5)(b) proviso, not merely clause (g).
Taxpayers often misunderstand that all expenses incurred by the legal entity are eligible unless expressly blocked; inward supplies diverted for “other purpose” or not used for business require reversal.
4.10 Section 17(5)(h): Goods lost, stolen, destroyed, written off, gifted or given as free samples
This clause applies only to goods, not services. It also distinguishes between taxable promotional schemes and free disposals.
If goods are supplied as part of a taxable composite/mixed supply or under a taxable promotional scheme with consideration embedded in price, the taxpayer may argue that there is no “gift” or “free sample”. But where goods are disposed without consideration as gifts/free samples, ITC is blocked. Gifts and samples are liable to credit reversal when they are not liable to output tax as a supply.
4.11 Section 17(5)(i): Tax paid under sections 74 / 129 / 130, and current position
This clause is not about inward supplies. It blocks credit of tax paid as a consequence of proceedings such as fraud/suppression or specified enforcement actions.
Tax paid in proceedings under sections 74, 129 and 130 will be blocked credit and that care must be taken to verify that such tax is not claimed as ITC. It also notes that tax paid under section 129 is not levied under section 9 but due to violation of section 68.
The current official version of section 17(5)(i) shows blockage for tax paid under section 74 in respect of any period up to FY 2023-24.
5. Blocked ITC versus non-availability of ITC under rate notification
This distinction is very important.
Blocked ITC arises when tax is charged on inward supply, the supply may be used for business, but credit is denied by section 17(5). Example: food and beverages, certain motor vehicles, gifts, works contract for own immovable property.
Non-availability of ITC under rate/exemption notification arises when a concessional rate, exemption entry or special scheme itself carries a condition that ITC shall not be taken. Here, denial flows from the notification or scheme, not necessarily section 17(5).
| Particulars | Blocked ITC | ITC not available due to notification |
| Source | Section 17(5) | Rate/exemption notification or special scheme |
| Nature | Statutory bar despite business use | Conditional tax treatment |
| Example | Construction of own office building | Concessional rate subject to no ITC |
| Return treatment | Permanent reversal/non-availment | Depends on notification and reporting |
| Litigation focus | Interpretation of section 17(5) | Interpretation of notification condition |
Thus, all ineligible ITC is not “blocked ITC”. Blocked ITC is a narrower category arising from section 17(5).
6. Accounting entries for blocked ITC
Blocked ITC should not remain in Input GST ledger as recoverable tax. It should be expensed or capitalised depending on the nature of the inward supply.
6.1 Blocked ITC identified at invoice booking stage
Example: Expense ₹1,00,000 + GST ₹18,000, ITC blocked.
| Relevant Expense A/c Dr. | 1,18,000 |
| To Vendor A/c | 1,18,000 |
| Better audit trail: | |
| Relevant Expense A/c Dr. | 1,00,000 |
| Blocked ITC Expense A/c Dr. | 18,000 |
| To Vendor A/c | 1,18,000 |
6.2 Partly eligible and partly blocked ITC
Example: GST ₹18,000; eligible ₹10,000; blocked ₹8,000.
| Relevant Expense A/c Dr. | 1,00,000 |
| Input GST A/c Dr. | 10,000 |
| Blocked ITC Expense A/c Dr. | 8,000 |
| To Vendor A/c | 1,18,000 |
6.3 Blocked ITC on capital asset
If GST is blocked on capital expenditure:
| Fixed Asset A/c Dr. | 11,80,000 |
| To Vendor A/c | 11,80,000 |
| If GST is eligible: | |
| Fixed Asset A/c Dr. | 10,00,000 |
| Input GST A/c Dr. | 1,80,000 |
| To Vendor A/c | 11,80,000 |
6.4 ITC wrongly availed and later identified as blocked
| Original entry: | |
| Expense A/c Dr. | 1,00,000 |
| Input GST A/c Dr. | 18,000 |
| To Vendor A/c | 1,18,000 |
| On reversal: | |
| Blocked ITC Expense A/c Dr. | 18,000 |
| To Input GST A/c | 18,000 |
If utilised, interest under section 50 read with Rule 88B must be examined.
6.5 Temporary reversal capable of re-availment
For Rule 37 or Rule 37A temporary reversal:
| ITC Reversal Recoverable A/c Dr. | 18,000 |
| To Input GST A/c | 18,000 |
| On re-availment: | |
| Input GST A/c Dr. | 18,000 |
| To ITC Reversal Recoverable A/c | 18,000 |
6.6 Reverse charge where ITC is blocked
For Booking RCM liability:
| RCM Input Tax Expense / Blocked ITC A/c Dr. | 18,000 |
| To GST RCM Payable A/c | 18,000 |
| Entry on Payment: | |
| GST RCM Payable A/c Dr. | 18,000 |
| To Bank / Electronic Cash Ledger A/c | 18,000 |
No Input GST entry should be passed where RCM credit is blocked.
7. Disclosure in GSTR-3B
GSTN instructions and return utilities require proper classification in Table 4 of GSTR-3B. The GST portal states that ITC claimed/reversed in Table 4A and 4D(2) is auto-populated from GSTR-2B, though taxpayers may add or modify details before filing.
Practical reporting:
| Nature of ITC | GSTR-3B treatment |
| Eligible ITC | Table 4(A), net to Table 4(C) |
| Permanent reversal, including section 17(5) | Table 4(B)(1) |
| Temporary reversal, reclaimable later | Table 4(B)(2) |
| Re-availment of earlier temporary reversal | Table 4(A)(5) |
| Disclosure of reclaimed ITC | Table 4(D)(1) |
| ITC not available as per GSTR-2B | Table 4(D)(2), where applicable |
GSTN’s advisory on changes in Table 4 of GSTR-3B states that ITC reversed under Table 4(B)(2) can be reclaimed in Table 4(A)(5) at the appropriate time, and the break-up of such reclaimed ITC is required to be provided in Table 4(D)(1).
Therefore, section 17(5) blocked ITC should generally not be parked in Table 4(B)(2) as reclaimable ITC.
Circular No. 170/02/2022-GST dated 06.07.2022 — Reporting of ineligible ITC and section 17(5) in GSTR-3B
This is a very important circular for return disclosure. CBIC clarified that Net ITC available as per Table 4(C) of GSTR-3B gets credited into the Electronic Credit Ledger. Therefore, any reversal of ITC or any ITC which is ineligible under any provision of the CGST Act should not become part of Net ITC in Table 4(C).
The circular further clarifies that ineligible ITC under section 17(5) and other reversals required under the Act and Rules should be made under Table 4(B) and not under Table 4(D) of Form GSTR-3B. It also gives an illustration where goods on which ITC is barred under section 17(5) are auto-populated in Table 4(A)(5), but the taxpayer is required to reverse/report the same properly so that only eligible net ITC reaches the Electronic Credit Ledger.
8. GSTN advisories on ITC reversal and re-availment
GSTN has introduced the Electronic Credit Reversal and Re-claimed Statement to track ITC reversed in Table 4(B)(2) and later reclaimed in Table 4(A)(5) and Table 4(D)(1).
The GST portal manual also states that taxpayers can view the statement of total ITC reversed and total ITC re-claimed through the Electronic Credit Reversal and Re-claimed Statement.
Important compliance points:
Step 1: Start with ITC auto-populated from GSTR-2B.
Step 2: Identify section 17(5) blocked ITC and other permanent ineligible ITC.
Step 3: Do not allow permanent ineligible ITC to become net ITC in Table 4(C).
Step 4: Report permanent reversals in Table 4(B)(1), wherever applicable.
Step 5: Report temporary reversals in Table 4(B)(2).
Step 6: Reclaim only legally eligible earlier reversed ITC in Table 4(A)(5).
Step 7: Disclose reclaimed ITC in Table 4(D)(1).
Step 8: Reconcile with the Electronic Credit Reversal and Re-claimed Statement.
GSTN’s GSTR-2B manual also provides that Rule 37A reversal information is available in GSTR-2B where ITC is to be reversed due to non-payment of tax by supplier.
The key caution is that GSTN’s reclaim facility is only a reporting mechanism. It cannot convert ineligible ITC into eligible ITC. Section 17(5) blocked ITC is not reclaimable merely because it appears in portal data.
Conclusion
Blocked ITC under GST is not merely an accounting adjustment. It is a statutory restriction. Section 16 gives the entry point for ITC, but section 17 decides whether the credit survives. Section 17(5), by using a non-obstante clause, can block ITC even where the expenditure is incurred for business.
Taxpayers must distinguish between eligible ITC, blocked ITC, proportionate reversal, temporary reversal and notification-based non-availability. Books of accounts should not carry permanently blocked ITC as recoverable tax. GST returns should also ensure that blocked ITC does not flow into net ITC in Table 4(C).
A legally sustainable ITC position requires statutory analysis, proper accounting, GSTR-2B reconciliation, correct GSTR-3B reporting and careful tracking of re-availment through GSTN statements.
Circulars on blocked credit show that section 17 is not to be applied mechanically. In some cases, such as food, beverages and employee benefits, the proviso may save credit where statutory obligation exists. In motor vehicle cases, the actual use and outward supply model decide the result. In construction and immovable property cases, the “plant and machinery” test may save credit where the item is functionally part of apparatus/equipment used for outward supply and is not specifically excluded. On the other hand, free samples, gifts, destroyed goods and personal consumption remain strong areas of blockage. Therefore, every ITC review should include not only section 16 and section 17, but also CBIC circulars, GSTN reporting advisories, accounting treatment and GSTR-3B Table 4 classification.
Disclaimer: This article is for educational and professional discussion only. It does not constitute legal opinion or professional advice. ITC eligibility depends on facts, documentation, contractual terms, accounting treatment, nature of outward supplies, applicable notifications, circulars and judicial developments. Professional advice should be obtained before taking any position in GST returns, audits, notices, appeals or litigation.
