Which Input Tax Credit Is Blocked Under GST Section 17(5)?

Blocked input tax credit is credit that Section 17(5) of the CGST Act denies even when every Section 16 condition is met. The tax paid on such a purchase is not recoverable as credit; it becomes part of the cost of the purchase. The bar applies across twelve clauses, 17(5)(a) to (i). It reaches motor vehicles for the transport of persons seating not more than thirteen including the driver, food and beverages, club and fitness memberships, and vacation benefits given to employees. It also reaches works contract and construction of immovable property, personal consumption, and goods lost, stolen, destroyed or gifted. Some clauses carry an exception that restores the credit and some carry none. Finance Act, 2025, section 124 substituted "plant and machinery" for "plant or machinery" in clause (d) retrospectively from 1 July 2017, reversing the Supreme Court's reading in Safari Retreats. Blocking under Rule 86A is a separate, administrative restriction and is not a Section 17(5) bar.

A registered person loses input tax credit under twelve clauses of Section 17(5) of the CGST Act, 2017, running from clause (a) to clause (i).

• Motor Vehicles: Clause (a) blocks motor vehicles for the transport of persons with an approved seating capacity of not more than thirteen persons, including the driver. Clauses (aa) and (ab) extend the bar to vessels, aircraft, and their insurance, servicing and repair.
• Food and Beverages: Clause (b)(i) blocks food, beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery, the leasing, renting or hiring of blocked vehicles, and life and health insurance. Clause (b)(ii) blocks club, health centre and fitness centre membership, subject only to the obligation exception at the end of clause (b).
• Construction: Clauses (c) and (d) block works contract services and own-account construction of immovable property other than plant and machinery. Clause (c) permits credit on a works contract taken as an input for another works contract; clause (d) permits none.
• Personal Consumption: Clause (g) blocks goods or services used for personal consumption, whoever the invoice is addressed to.
• Lost or Destroyed Goods: Clause (h) blocks goods lost, stolen, destroyed, written off, or disposed of by gift or free sample.
• Employee Travel Benefits: Clause (b)(iii) blocks leave travel concession and home travel concession given to employees on vacation.
• CSR Spending: Clause (fa) blocks goods or services used for activities relating to a company's corporate social responsibility obligations.
• Composition and Non-Resident Supplies: Clauses (e) and (f) block supplies taxed under the composition levy and inward supplies received by a non-resident taxable person. Clause (f) permits credit on goods the non-resident has imported himself; clause (e) permits none.
• Tax Paid Under Section 74: Clause (i) blocks any tax paid under Section 74 in respect of any period up to Financial Year 2023-24.

The meaning of blocked here is narrow and exact: the section denies the credit outright. A blocked credit is not a timing problem and not a documentation problem. The supply is on the list, so the credit never arose, and the tax paid becomes part of the cost of the purchase.

The bar operates on the entitlement rather than on the paperwork. Section 17(5) opens with the words "notwithstanding anything contained in sub-section (1) of section 16 and sub-section (1) of section 18". A business that satisfies every one of the Section 16 conditions still gets nothing where a clause applies. That is why a blocked credit cannot be cured by obtaining a better invoice or by paying the supplier faster.

The override applies to Section 18(1) as well. That is the provision letting a person take credit on stock held when registration is first obtained, or when an exempt supply becomes taxable. A business entering the credit chain for the first time therefore takes its opening credit subject to the same list. The practical effect is that Section 17(5) is checked against the nature of the supply before any question of eligibility, timing or documentation is reached at all.

A blocked credit claimed in error must be reversed, and interest runs on it only where the credit was actually utilised.

• Reversal: The credit is reversed in the GSTR-3B for the period in which the error is found, in Table 4(B)(1). A blocked credit still appears in GSTR-2B and still auto-populates into the return, so the reversal is something you do, not something the portal does for you.
• Interest: Section 50(3) charges interest only where the credit was wrongly availed and utilised, and Rule 88B determines the period over which it runs.
• No interest on an unused credit: Credit claimed in error that simply remained in the electronic credit ledger and was never used to pay tax carries no Section 50(3) interest at all.
• Notices and penalty: The department may raise a demand, and penalty is assessed separately and is heavier where fraud or wilful misstatement is alleged.

Because a Section 17(5) credit was never available in the first place, the department treats it as wrongly availed rather than as a timing error. A demand for wrongly availed credit runs under Section 73 or Section 74 for periods up to Financial Year 2023-24, and under Section 74A from Financial Year 2024-25. Each section sets its own time to issue the notice and pass the order.

Twelve lettered clauses make up Section 17, sub-section (5), and whether an exception restores the credit depends on which clause applies.

Section 17(5)(a): Motor Vehicles for the Transport of Persons

Input tax credit is blocked on motor vehicles for the transportation of persons with an approved seating capacity of not more than thirteen persons, including the driver.

• Further supply: Credit is available where the vehicle is bought for onward sale, as by a dealer.
• Transportation of passengers: Credit is available where the vehicle is used to supply passenger transport services.
• Driving training: Credit is available where the vehicle is used to impart training on driving such vehicles.

Goods carriers are outside clause (a) altogether. The bar applies only to vehicles for the transportation of persons, so a truck or a delivery van is not blocked by this clause. Further questions of seating capacity, of use and of the related services arise for cars and motor vehicles.

Section 17(5)(aa): Vessels and Aircraft

Input tax credit is blocked on vessels and aircraft, except where they are used for further supply, transportation of passengers, training on navigating vessels, training on flying aircraft, or transportation of goods.

Section 17(5)(ab): Insurance, Servicing and Repair of Those Vehicles, Vessels and Aircraft

Input tax credit is blocked on general insurance, servicing, repair and maintenance. The bar reaches those services so far as they relate to a motor vehicle, vessel or aircraft referred to in clause (a) or clause (aa).

• Eligible use: Credit is available where the vehicle, vessel or aircraft is used for one of the purposes clause (a) or clause (aa) permits.
• Manufacturers: Credit is available to a person engaged in manufacturing such motor vehicles, vessels or aircraft.
• Insurers: Credit is available to a person supplying general insurance in respect of such vehicles insured by him.

Section 17(5)(b): Food, Beverages, Memberships and Employee Travel

Clause (b) blocks three separate groups of supplies and contains two provisos: one reaching the first group only, and one reaching all three.

• Food, beverages and personal services: Food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery, leasing, renting or hiring of blocked vehicles, life insurance and health insurance.
• Memberships: Membership of a club, health and fitness centre, subject only to the obligation exception at the end of the clause.
• Employee travel benefits: Travel benefits extended to employees on vacation, such as leave travel concession or home travel concession.

The first group is restored where the same category of inward supply is used to make an outward taxable supply, or forms an element of a taxable composite or mixed supply. All three groups are restored where a law in force makes it obligatory for the employer to provide the supply to its employees. CBIC clarified in Circular No. 172/04/2022-GST dated 6 July 2022 that the proviso written after sub-clause (iii) applies to the whole of clause (b). The obligation exception therefore reaches food and beverages and insurance under sub-clause (i), and club and fitness membership under sub-clause (ii), and not only the travel benefits in the sub-clause it follows. The leasing, renting and hiring of vehicles inside the first group carries its own qualification. Those supplies fall outside the bar where the vehicle is used for a purpose clause (a) or clause (aa) permits. CBIC has settled one word in sub-clause (i). Leasing there refers only to the leasing of motor vehicles, vessels and aircraft, which is what the sub-clause's own words say, so a lease of plant, premises or equipment is not blocked by sub-clause (i) at all. As to those vehicles, vessels and aircraft the statute blocks leasing, renting and hiring alike. Note the width of the words the statute uses there. It blocks leasing, renting or hiring, so an arrangement described as a lease rather than a hire is inside the clause on the same terms.

Section 17(5)(c): Works Contract Services for Immovable Property

Input tax credit is blocked on works contract services supplied for construction of an immovable property other than plant and machinery.

• Further supply: Credit is available where the works contract service is an input service for the further supply of works contract service, which is the sub-contractor to contractor case.

Section 17(5)(d): Construction on Your Own Account

Input tax credit is blocked on goods or services received for construction of an immovable property other than plant and machinery on your own account. The bar applies even where the property is used in the course or furtherance of business.

"Construction" here includes re-construction, renovation, additions, alterations and repairs, to the extent they are capitalised, under Explanation 1. The capitalisation words are operative, and note where they attach. They qualify the five extensions the Explanation adds to the word, not construction in its primary sense, so constructing a building falls within the clause whether or not the spend is capitalised. Expenditure on re-construction, renovation, additions, alterations or repairs to the same building that is charged to the profit and loss account rather than capitalised falls outside the definition. The clause (d) bar does not reach it, so for those five the credit depends on the accounting treatment. Whether a building can ever be "plant" for this clause is the question Safari Retreats and Finance Act, 2025 answer. The answer changed with effect from 1 July 2017, by a substitution that itself came into force on 1 October 2025.

Section 17(5)(e): Supplies Taxed Under the Composition Scheme

Input tax credit is blocked on goods or services on which tax has been paid under Section 10, the composition levy. There is no exception.

Section 17(5)(f): Supplies Received by a Non-Resident Taxable Person

Input tax credit is blocked on goods or services received by a non-resident taxable person, except on goods imported by him.

Section 17(5)(fa): Corporate Social Responsibility Spending

Input tax credit is blocked on goods or services used or intended to be used for activities relating to a taxable person's corporate social responsibility obligations. Those obligations arise under Section 135 of the Companies Act, 2013. There is no exception.

Clause (fa) was inserted into Section 17(5) by section 139 of the Finance Act, 2023, which placed it immediately after clause (f), and it took effect on 1 October 2023.

Section 17(5)(g): Personal Consumption

Input tax credit is blocked on goods or services used for personal consumption. Addressing the invoice to the business does not change the answer, because the test is actual use.

Section 17(5)(h): Goods Lost, Stolen, Destroyed, Written Off or Gifted

Input tax credit is blocked on goods lost, stolen, destroyed, written off, or disposed of by way of gift or free samples. Where credit was already taken, it must be reversed.

Clause (h) applies at a different moment from the rest. The other clauses can be applied at the moment of purchase, because the nature of the supply is known then. Clause (h) turns on what later happens to the goods, so a credit taken correctly becomes blocked by an event after the claim. Stock written off at a year end, and promotional goods given away, are the common occasions for a reversal under this clause.

Section 17(5)(i): Tax Paid Under Section 74

Input tax credit is blocked on any tax paid in accordance with Section 74 in respect of any period up to Financial Year 2023-24. Section 74 is the provision dealing with demands that involve fraud, wilful misstatement or suppression of facts.

That wording is narrower than the clause once was. Section 119 of the Finance (No. 2) Act, 2024 substituted it for the former reference to "sections 74, 129 and 130". Detention, seizure and confiscation are therefore outside this bar, and the clause is confined to a closed set of past years. Section 74A, which governs demands from Financial Year 2024-25, is a different section and is not named in the clause.

Whether Section 74 is available to the department at all is a live question where the credit was lawful when it was claimed. The Andhra Pradesh High Court heard a construction company in March 2026 whose credit for 2019-20 to 2023-24 was met with a Section 74 notice alleging wilful misstatement. It took the prima facie view that the claim had been permissible when it was made. On that footing it was not clear how the claim could be treated as wilful misstatement or suppression, and the jurisdictional fact for Section 74 appeared to be absent. It stayed the proceedings. The point has not been decided.

A blocked credit was never available; a blocked ledger holds a credit you have but cannot spend; a reversed credit was available, was claimed, and had to be given back. The provision you are arguing about depends on which of the three applies.

• Blocked credit (Section 17(5)): The credit never arises. The supply is on the blocked list, so nothing was ever claimable.
• Blocked ledger (Rule 86A): The credit is valid, but the balance in your electronic credit ledger is frozen and cannot be debited. An officer imposes it on reasons recorded in writing under Rule 86A, and it lapses after a year.
• Reversed credit (Rules 37, 42, 43 and 44): The credit arose and was claimed, then a later event, such as non-payment, exempt use or the sale of capital goods, required it back. Each of those rules fixes its own amount and its own period for the reversal of input tax credit.

Only the first is a Section 17(5) bar. A Rule 86A block is an officer's action on your ledger, and a reversal is an entry in Table 4(B) of GSTR-3B. Rule 86A and the reversal rules are in the CGST Rules, 2017, while the blocked list is in the Act. A business can be denied input tax credit (ITC) on three separate footings: the Act's own list, an officer's order, or a later event. Which provision you are arguing about follows from the difference between them.

How to Check Whether Your ITC Is Blocked

A Rule 86A block shows in the electronic credit ledger on the GST portal, where the blocked amount is displayed against the ledger balance. A Section 17(5) bar shows nowhere, because it is a question about the supply and not about the ledger.

How to Unblock Blocked ITC in GST

A Rule 86A restriction is lifted by the officer who imposed it, or it lapses by operation of Rule 86A(3). A credit blocked by Section 17(5) cannot be unblocked at all, because it never arose.

An employer gets no input tax credit on employee insurance, canteen, cab and health services, all of which fall within Section 17(5)(b). The proviso that restores credit where a law in force compels the benefit is placed after clause (b)(iii), and CBIC has clarified that it applies to the whole of clause (b).

• Group health and life insurance: Blocked under clause (b)(i), and restored where a law in force obliges the employer to provide the cover.
• Canteen and food provided to staff: Blocked under clause (b)(i), restored where the employer supplies the food onward as a taxable supply of the same category, and restored where a law in force obliges the employer to provide the canteen.
• Employee cabs and hired vehicles: Blocked where the vehicle is one referred to in clause (a) or clause (aa). Restored where the hire is used for a purpose those clauses permit, and restored where a law in force obliges the employer to provide the transport.
• Club, health centre and gym membership: Blocked under clause (b)(ii), whoever the member is, unless a law in force obliges the employer to provide it.
• Leave travel and home travel concession: Blocked under clause (b)(iii), and restored where a law in force makes it obligatory for the employer to provide the benefit.

Clause (b) contains two provisos and their reach differs. The first appears in sub-clause (i) and applies to that sub-clause only. Credit is available where a registered person uses the inward supply to make an outward taxable supply of the same category, or supplies it as an element of a taxable composite or mixed supply. The second appears after sub-clause (iii), and CBIC has clarified that it applies to the whole of clause (b). A claim based on the obligation for insurance or a canteen therefore stands on the same footing as one for travel benefits. A claim under it should still record the law relied on. A factory canteen compelled by the Factories Act, 1948 is the example most often given of such an obligation. A business relying on it should keep working papers identifying the statute.

A reported GST Council Law Committee recommendation would allow input tax credit on vehicles bought in a company's name for employee use and on group insurance. No official record of that recommendation has been published, the GST Council has not adopted it, and no notification, circular or Act gives it legal effect. Until Section 17(5) is amended and the amendment is brought into force, the credit remains blocked. Pending amendments have no legal effect until they are enacted and commenced.

One practical consequence follows from the terms of the exception. Because it turns on a statutory obligation rather than on commercial necessity, the working papers have to name the law relied on. A recovery from employees may also turn the supply into an onward taxable supply in its own right.

The same expense is eligible for one business and ineligible for another, because the clauses that carry an exception turn on what the buyer does with the supply.

Inside Section 17(5), an expense is allowed rather than blocked principally on one of four grounds. The buyer puts the vehicle to a use clause (a) or clause (aa) permits, or makes an outward taxable supply of the same category. Or a law in force compels the expense, or the asset is plant and machinery rather than a building. Two narrower routes fall outside those four: clause (f) permits credit on goods a non-resident has imported himself, and clause (ab)'s proviso permits credit to a manufacturer of the vehicles, vessels or aircraft. No row changes because the spend was commercially sensible or because the invoice carries the company's GSTIN.

The clause (h) row needs a second look, because CBIC has read it narrowly. Circular No. 92/11/2019-GST of 7 March 2019 clarifies that where the distribution of gifts or free samples is itself a supply under Schedule I, the supplier remains eligible for the credit. The same circular states that a buy-one-get-one offer is not an individual supply of free goods but two or more supplies at a single price, so the credit on both survives.

A supply carrying its own rate-linked condition that denies input tax credit is a different thing from a Section 17(5) bar. Section 17(5) itself was not amended by the GST 2.0 rate changes. Where a rate notification prescribes such a condition, CBIC publishes it with the rate and not in Section 17(5).

Every exception in Section 17(5) but one is defined by what the buyer supplies onward, so the same purchase is blocked or allowed according to the business making it.

• Passenger transport operators and cab aggregators: Vehicles used to supply passenger transport services are outside clause (a)'s bar, and so are their insurance, servicing and repair under clause (ab).
• Motor dealers: Vehicles bought for further supply are outside clause (a), and manufacturers of such vehicles are expressly covered by clause (ab)'s proviso.
• Driving schools: Vehicles used to impart training on driving such vehicles are outside clause (a).
• Restaurants, hotels and caterers: Food and beverages bought as an input for an outward taxable supply of the same category are restored by clause (b)(i)'s proviso.
• Insurers: A person supplying general insurance on such vehicles may take credit on the insurance, servicing and repair services under clause (ab). Clause (a) still governs the vehicle itself, and being an insurer is not one of its three exceptions.
• Works contractors and sub-contractors: A works contract service received as an input for the further supply of works contract service is outside clause (c)'s bar.
• Employers under a statutory obligation: Where a law in force compels the supply, the proviso after clause (b)(iii) restores the credit, and CBIC has clarified that it reaches the whole of clause (b), insurance and canteen included.

Six bars have no business-type route at all. They are clause (d) own-account construction, clause (e) composition supplies and clause (fa) corporate social responsibility spending, and to those add clause (g) personal consumption, clause (h) lost and gifted goods, and clause (i) tax paid under Section 74. None of them carries a carve-out or a proviso, so no trade or industry gets the credit. Clause (b)(ii) membership has no business-type route either, though the obligation proviso reaches it.

The Supreme Court in Safari Retreats held on 3 October 2024 that a building functioning as plant falls outside the Section 17(5)(d) bar. Finance Act, 2025, section 124 then substituted "plant and machinery" for the "plant or machinery" that reasoning turned on, and deemed the substitution to have taken effect from 1 July 2017. It also inserted Explanation 2, providing that the reference is to be so construed notwithstanding anything to the contrary in any judgment, decree or order of any court, tribunal or other authority.

The exception in clauses (c) and (d) remains applicable. They bar construction of immovable property other than plant and machinery. Credit on apparatus, equipment and machinery fixed to earth by foundation or structural support, and used for making an outward supply, was never blocked and is not blocked now. The definition excludes land, buildings and other civil structures, telecommunication towers, and pipelines laid outside factory premises, so it is narrower than it first sounds. Because the substitution is deemed effective from 1 July 2017, the question for every period is whether the asset answers the statutory definition of plant and machinery rather than whether the building functions as plant. Section 124 itself came into force on 1 October 2025, under Notification No. 16/2025-Central Tax of 17 September 2025. What that means for a mall, a warehouse and a factory building depends on the rules governing construction of immovable property.

Safari Retreats also upheld the constitutional validity of clauses (c) and (d), and that holding was not touched by the substitution. And the retrospective reach of the substitution is under challenge. The Orissa High Court entertained it in December 2025 and the Andhra Pradesh High Court in Kavya Avenues LLP, W.P. 6315/2026, on 18 March 2026. Neither has decided it, and both granted interim protection to the taxpayer before them. A Delhi High Court order of 10 August 2026 is sometimes read as a third matter and is not one. It disposed of two petitions challenging the validity of clauses (c) and (d), recording that validity had already been put to quietus by Safari Retreats. Retrospectivity appears in it once, as a submission of counsel on which the Bench said nothing, and no protection was granted. What the order does hold is that Circular No. 28 (Flyer) of 1 January 2018, which predates Safari Retreats, must now be read in accordance with that judgment, which the Revenue did not dispute. The arguments concern how far a deeming provision enacted in 2025 can govern a claim made years earlier. A second argument is whether a claim lawful when made can support an allegation of suppression. A business with periods before the amendment should therefore take advice on its own facts rather than assume the position is closed either way.
