Last updated: 22 April 2026. Section 17(5) of the CGST Act lists specific categories of goods and services on which Input Tax Credit is blocked, even if the GST was charged correctly by the supplier and the invoice meets every other condition under Section 16. These are not eligibility issues you can fix by reconciling GSTR-2B or chasing a vendor. They are hard blocks built into the law, and most ITC notices that look unfair on first reading turn out to be Section 17(5) cases.
Applicability Note: This guide is based on Section 17(5) of the CGST Act, 2017 as amended through the Finance Act 2025, and the corresponding rules and circulars in force on 22 April 2026. The clause-by-clause treatment, especially around motor vehicles, construction, and Section 74 demands, has been amended several times since 2017. Verify the current text of Section 17(5) on taxinformation.cbic.gov.in or with a GST professional before relying on any specific carve-out.
Who should care?
- Any GST-registered business claiming ITC in GSTR-3B
- Companies with employee-related expenses (food, insurance, vehicles)
- Businesses building or renovating their own office, warehouse, or factory
- Finance and accounting teams reconciling GSTR-2B with the books
1. What "Blocked Credit" Actually Means
Section 16 of the CGST Act tells you when you are eligible for Input Tax Credit. Section 17(5) carves a list out of that eligibility. So even if your purchase satisfies every Section 16 test (valid tax invoice, goods or services received, supplier has filed GSTR-1, GST appears in your GSTR-2B, payment within 180 days), the credit is still blocked if the item falls into one of the 11 sub-clauses of Section 17(5).
Practically, this means you must:
- Claim the ITC in Table 4(A) of GSTR-3B initially (since GSTR-2B will show it as available)
- Reverse it in Table 4(B)(1) of GSTR-3B as "ITC reversed under Section 17(5)" in the same return
- Account for the GST as part of the cost in your books, not as a recoverable asset
Most accounting software and the GSTR-2B itself now flag Section 17(5) categories explicitly so they can be reversed correctly. If your reconciliation software does not, expect a DRC-01C mismatch notice eventually.
2. The 11 Blocked Categories at a Glance

| 17(5)(aa) | Vessels and aircraft | Same as above (transportation business or further supply) |
| 17(5)(ab) | Services of insurance, servicing, repair and maintenance on the above blocked vehicles/vessels/aircraft | Allowed where the vehicle itself is eligible for ITC |

| 17(5)(b)(iii) | Travel benefits to employees on vacation, including leave or home travel concession | Where the law makes it obligatory to provide |
| 17(5)(c) | Works contract services for construction of immovable property | Where it is an input service for further supply of works contract; plant and machinery is not blocked |

3. The Categories That Catch People Out the Most
Motor vehicles and the ≤13-seater test
The popular myth is that ITC is allowed on a car as long as it is "for business use". The actual test in clause (a) is the seating capacity. Vehicles approved to carry no more than 13 persons, including the driver, are blocked, regardless of whether they are used for business purposes. A company-owned Innova used by the management is blocked. A 25-seater bus shuttling employees between sites is not.
The carve-outs are narrow: ITC opens up only if the vehicle is used for further supply (i.e., resold), for transportation of passengers as a taxable service (cabs, fleets), or for imparting driving training. Director-shuttle, sales-team-pool, and Diwali gift cars are all blocked.
Food, beverages and employee insurance
Clause (b)(i) blocks ITC on food and beverages. The hidden carve-out is the closing proviso: ITC is allowed where the goods or services in question are used by a registered person for making an outward taxable supply of the same category, or where it is statutorily obligatory for the employer to provide them. So a restaurant claiming ITC on food ingredients is fine. A factory providing canteen food because the Factories Act mandates it is also fine. A general office buying lunch for a client meeting is not.
The same logic applies to health insurance: it is blocked unless the law (Factories Act, employment standing orders, state rules) makes it compulsory. Group health insurance taken voluntarily by the employer remains blocked.
Construction of immovable property
Clauses (c) and (d) together block ITC on most construction-related procurement, whether through a works contract or by procuring inputs and labour separately. The exception for "plant and machinery" has been the most litigated phrase in this section. After the Supreme Court's Safari Retreats judgment, the Finance Act 2025 amended clause (d) to replace "plant or machinery" with "plant and machinery", aligning the language with clause (c). The effect is to keep the narrow definition of plant and machinery (excluding land, buildings, and other civil structures) as the only ITC-eligible component of a construction project.
Lost, stolen, destroyed, gifted goods
Clause (h) is the source of most year-end ITC reversals. If you have written off slow-moving stock, distributed Diwali gifts, given away free samples, or had inventory destroyed by fire or flood, the ITC originally claimed on those goods has to be reversed. This often surfaces only at the time of the GSTR-9 reconciliation, by which point interest under Section 50 has been ticking for months.
4. How Section 17(5) Interacts with GSTR-2B
The portal does not stop you from claiming Section 17(5) ITC. GSTR-2B will show the input tax appearing against your GSTIN as available, because the supplier has reported it correctly. The block is your responsibility to identify and reverse. The "ineligible ITC" tab in GSTR-2B helps by flagging supplier-side ineligibility (place of supply mismatches, time-barred invoices) but it does not classify Section 17(5) blocks for you, because that depends on how you used the input.
Best practice: Tag every purchase invoice in your accounting software with one of three flags: "ITC eligible", "ITC blocked under 17(5)", or "Reversal pending under Rule 42/43". Then reconcile the totals against GSTR-2B and Table 4(B) of GSTR-3B every month. This catches blocks before the year ends.
5. Key Takeaways
- Section 17(5) blocks ITC on 11 specific categories regardless of business purpose
- The GST portal will show the credit as available; you have to reverse it in Table 4(B)(1) of GSTR-3B
- Motor vehicles up to 13 seats are blocked except for cabs, fleets, driving schools, or resale
- Food, club memberships, and most health insurance are blocked unless the same category is your output supply or the law mandates the spend
- Construction inputs are blocked except for narrowly defined plant and machinery (Finance Act 2025 alignment)
- Goods lost, stolen, written off, gifted, or sampled trigger an ITC reversal
- Tax paid under Section 74, 129, or 130 is blocked, with limited Finance Act 2024 relaxation for older periods
Frequently Asked Questions
Can a company claim ITC on a car bought for the CEO?
No. The car is a motor vehicle for transport of persons with seating capacity below 13, used for personal-cum-business movement. Clause 17(5)(a) blocks the ITC, with no available carve-out for executive use.
Is health insurance for employees eligible for ITC?
Only if it is statutorily obligatory for the employer to provide it. A voluntary group health insurance policy is blocked under clause 17(5)(b)(i).
What is "plant and machinery" for the purposes of construction ITC?
The Explanation under Section 17 defines plant and machinery as apparatus, equipment, and machinery fixed to earth by foundation or structural support that is used for making outward supply of goods or services. It specifically excludes land, building or other civil structures, telecommunication towers, and pipelines laid outside the factory premises. Finance Act 2025 extended the same definition to clause (d) so the test is uniform across the section.
If GSTR-2B shows ITC as available, can I claim it even if it is blocked?
You can claim it in Table 4(A) but you must immediately reverse the same amount in Table 4(B)(1) of the same GSTR-3B. The portal does not enforce Section 17(5) for you. Failure to reverse leads to interest under Section 50 and possible penalty.
Is ITC on free samples really blocked?
Yes. Clause 17(5)(h) explicitly covers goods disposed of by way of gift or free samples. The original ITC on inputs and the proportionate ITC on packing material has to be reversed in the month the samples are issued.
