Section 17(5) CGST Act
The Complete Expert Guide
Every category of blocked Input Tax Credit explained — with HSN & SAC codes, exceptions, GSTR-3B reporting tables, Budget 2025-26 amendments, and the real cost of getting it wrong.
Every month, thousands of Indian businesses unknowingly claim blocked credit under GST — Input Tax Credit that Section 17(5) of the CGST Act explicitly prohibits. The result: show cause notices, mandatory ITC reversals, and interest at 24% per annum on wrongly claimed amounts. This is one of the most common and most expensive GST compliance errors in India. This guide covers every clause with plain-language explanations, real examples, exceptions, and reporting requirements.
What Is Blocked Credit Under GST?
Blocked credit under GST refers to Input Tax Credit (ITC) that a registered taxpayer is explicitly prohibited from claiming under Section 17(5) of the Central Goods and Services Tax (CGST) Act, 2017 — even if the supplier has charged GST on the supply, and even if the goods or services are used in the course of business.
ITC Not Available ⇒ Section 17(5) Overrides Section 16. Even if all general conditions under Section 16 are fulfilled, credit will still be denied if it falls under Section 17(5).
Section 17(5), CGST Act, 2017 — Non-obstante clauseThis is fundamentally different from ITC unavailability due to a failed condition under Section 16(2). Blocked credit is a statutory prohibition that applies regardless of whether all other ITC conditions are satisfied. The blocked credit list in Section 17(5) is exhaustive, not illustrative — if an item is not mentioned, it is generally eligible for ITC subject to Section 16 conditions.
All 11 Categories of Blocked Credit — Clause by Clause
ITC is blocked on motor vehicles used for transportation of persons having seating capacity up to 13 persons (including the driver). This is one of the most frequently misapplied provisions — many businesses assume all vehicle-related GST is claimable.
| Vehicle Type | HSN Code | Status |
|---|---|---|
| Motor Cars (petrol/diesel/CNG) | 8703 | Blocked |
| Motorcycles & Scooters | 8711 | Blocked |
| Passenger Buses (≤13 seats) | 8702 | Blocked |
| Electric Cars | 8703 | Blocked |
| Auto Rickshaws | 8703 / 8706 | Blocked |
| Trucks / Goods Vehicles | 8704 | Eligible |
- Company car for director's use
- Passenger van for employee commute
- Electric car purchased for management
- Further supply of such vehicles (car dealer)
- Passenger transportation business (cab operator)
- Driving training schools
Electric vehicles are also treated as motor vehicles under Section 17(5). The ITC restriction applies equally to EVs — there is no special exemption for battery-powered passenger vehicles.
ITC on servicing, repair, maintenance, and insurance of blocked vehicles is also not available. This is an important extension — even if a business doesn't buy the vehicle, it cannot claim ITC on its running costs if the vehicle itself is blocked.
| Service | SAC Code | Status |
|---|---|---|
| Motor Vehicle Repair & Servicing | 998714 | Blocked |
| Comprehensive Motor Insurance | 997134 | Blocked |
| Preventive Maintenance Services | 998719 | Blocked |
Blocked: A pharma company pays ₹15,000 + GST ₹2,700 for servicing the MD's car. The ₹2,700 GST is blocked — cannot be claimed as ITC.
Allowed: A fleet taxi company services its cabs. ITC on repairs and insurance is available because the vehicles are used for passenger transportation business.
ITC is blocked on food and beverages, outdoor catering, beauty treatment, cosmetic and plastic surgery, and health services. This clause is widely applicable for businesses that provide employee perks or hospitality services.
| Category | HSN/SAC | Status |
|---|---|---|
| Restaurant / Eating Services | 996331 | Blocked |
| Outdoor Catering Services | 996333 | Blocked |
| Packaged Food & Beverages | Ch. 1–22 | Blocked |
| Beauty Parlour Services | 999723 | Blocked |
| Cosmetic / Plastic Surgery | 999312 | Blocked |
Where a canteen facility is mandatory under the Factories Act (establishments employing 250+ workers), ITC on food and catering may be available subject to conditions. Voluntarily provided employee meals remain blocked.
Blocked: IT company orders lunch for employees every Friday as a perk → ITC on catering blocked.
Allowed: Manufacturing unit with 500 workers maintains canteen mandatory under Factories Act → ITC may be available.
Allowed: Hotel providing restaurant services can claim ITC on food purchases for its restaurant business (further supply of same category).
ITC is not available on club memberships and gym/fitness centre subscriptions purchased for employees or directors. This covers both one-time membership fees and recurring annual subscriptions.
| Service | SAC Code | Status |
|---|---|---|
| Fitness / Gym Centre Services | 999722 | Blocked |
| Club Membership (recreational) | 999598 | Blocked |
Blocked: Corporate takes 10 gym memberships at ₹12,000/year each + 18% GST for directors and senior managers. The GST of ₹21,600 is fully blocked.
ITC is blocked on rent-a-cab services, health insurance, and life insurance provided to employees. This is one of the most frequently contested provisions, particularly around employee group health insurance.
| Service | SAC Code | Status |
|---|---|---|
| Rent-a-Cab Services | 996601 | Blocked |
| Health / Medical Insurance | 997133 | Blocked |
| Life Insurance Services | 997132 | Blocked |
- Voluntary group health insurance for employees
- Director's personal life insurance policy
- Cab service for employee commute (not mandatory)
- Insurance mandated by law (e.g., ESIC, Construction Workers)
- Cab service for outward supply of same nature (cab aggregators)
- Insurance companies — ITC on insurance purchased for own supply
ITC is blocked on Leave Travel Allowance (LTA), vacation travel benefits, and holiday packages provided to employees on leave. This applies to travel costs paid or reimbursed by the employer for personal/holiday purposes.
| Service | SAC Code | Status |
|---|---|---|
| Air Travel Agency Services | 998551 | Blocked (if for LTA) |
| Tour Operator Services | 998552 | Blocked (if for vacation) |
Blocked: Company reimburses employee's family holiday package ₹80,000 + GST ₹9,600. The ₹9,600 GST cannot be claimed.
Note: Business travel for official purposes (client visits, training, conferences) is NOT blocked — only leisure/holiday travel benefits.
ITC is blocked on works contract services used for construction of immovable property (except Plant & Machinery). This affects businesses that hire contractors for building, civil work, or fitout of office/factory premises.
| Service | SAC Code | Status |
|---|---|---|
| Works Contract Services (Construction) | 9954 | Blocked (own use) |
| Construction of Residential Buildings | 995411 | Blocked |
| Construction of Commercial Buildings | 995413 | Blocked |
- Office building interior fitout contractor
- Factory shed construction
- Warehouse civil works
- Works contractor hiring sub-contractor for further supply of WCS
- Plant & machinery installation works
ITC is blocked for self-construction of immovable property — office buildings, commercial buildings, civil structures — even when built for business use. This is one of the most impactful blocked credit provisions for capital-intensive businesses.
| Input Material/Service | HSN/SAC | Status |
|---|---|---|
| Cement | 2523 | Blocked (for construction) |
| Steel / TMT Bars | 7214 | Blocked (for construction) |
| Tiles & Flooring | 6907 | Blocked |
| Construction Services | 9954 | Blocked |
The Finance Act 2025-26 introduced clarificatory amendments to Section 17(5)(d) to address interpretational disputes regarding the scope of "immovable property" for this clause. Businesses should review the updated provision carefully with their tax advisors.
ITC is not available on purchases from taxpayers registered under the Composition Scheme. Composition dealers pay tax at a flat rate and issue a "Bill of Supply" (not a tax invoice), so no ITC can be passed to the recipient.
Blocked: A retailer buys stationery worth ₹10,000 from a composition dealer who charges composition levy at 1%. The retailer cannot claim any ITC — even the composition tax paid by the dealer is not available as credit.
Always verify supplier registration status on the GSTN portal before claiming ITC. A supplier switching to composition during the year without notifying you can result in blocked credit claims being reversed.
ITC is not available to Non-Resident Taxable Persons (NRTP) except on goods imported by them into India. NRTPs are foreign entities registered under GST for temporary business activities in India (e.g., events, exhibitions). They can claim ITC only on the GST paid on their imports.
ITC is blocked on goods and services used for personal consumption — i.e., not used for the business. This is a broad category that requires careful segregation between personal and business use, especially for proprietors and partners.
| Category | HSN/SAC | Status |
|---|---|---|
| Mobile Phones (personal use) | 8517 | Partly blocked (personal portion) |
| Household Goods | Various | Blocked |
| Director's Personal Groceries | Ch. 1–22 | Blocked |
| Personal Services | Various | Blocked |
Where goods/services are used partly for business and partly for personal use, ITC must be apportioned. Only the business-use proportion can be claimed; the personal portion must be treated as blocked credit and reversed in GSTR-3B Table 4(B)(1).
ITC must be reversed on goods that are lost, stolen, destroyed, written off, or disposed of as gifts or free samples. This is a post-procurement block — ITC already claimed must be reversed when goods become subject to this clause.
- Free samples distributed to doctors by pharmaceutical companies — ITC blocked.
- Destroyed inventory due to fire, flood, or expiry — ITC to be reversed.
- Written-off stock at year-end — ITC reversal required.
- Promotional gifts to clients or dealers — ITC blocked.
- Stolen goods — ITC reversed upon confirmation of theft.
A pharmaceutical company distributes ₹5 lakh worth of physician samples + GST ₹45,000 to doctors. The ₹45,000 ITC is fully blocked under Section 17(5)(h). This applies even though the samples are "for business promotion."
ITC is not available on tax paid under Sections 74, 129, or 130 of the CGST Act. These sections relate to tax recovered in cases of fraud, wilful misstatement, suppression of facts, detention/seizure of goods, and confiscation proceedings.
Sec. 74: GST paid after adjudication for fraudulent ITC claims → ITC on that payment blocked.
Sec. 129: Tax paid during detention of goods and vehicle at a check post → Not available as ITC.
Sec. 130: Tax paid on confiscated goods → No ITC credit.
The Plant & Machinery Exception
One of the most important — and most misunderstood — aspects of Section 17(5) is that the ITC restriction on construction does not apply to Plant & Machinery. This distinction is critical for manufacturing businesses.
GST Return Reporting — GSTR-3B & GSTR-9
GSTR-3B Reporting
Blocked ITC must be disclosed in GSTR-3B under Table 4(B) — ITC Reversed. Specifically:
| Situation | GSTR-3B Table | Description |
|---|---|---|
| All blocked credit under Section 17(5) | Table 4(B)(1) | ITC reversed as per Section 17(5) |
| Personal use portion of dual-use inputs | Table 4(B)(1) | Reversed along with other 17(5) credits |
GSTR-9 Annual Return
| What to Report | GSTR-9 Table | Scope |
|---|---|---|
| ITC reversed and ineligible ITC | Table 7A | Cumulative blocked ITC for the year under Section 17(5) |
Incorrect reporting in GSTR-3B (claiming blocked credit in Table 4A instead of reversing in Table 4B) is the single most common cause of GST notices, refund rejections, and mismatch proceedings in blocked credit cases.

Monthly Blocked ITC Compliance Checklist
- Review all purchase invoices for the month against Section 17(5) clauses.
- Verify HSN/SAC codes of all input supplies against blocked credit list.
- Identify motor vehicles purchased or leased — check seating capacity ≤13 for block.
- Check all insurance premiums — health, life, motor vehicle — for employees/directors.
- Confirm canteen expenses — is it voluntary or mandatory under Factories Act?
- Review construction/works contract invoices — verify whether for P&M or building.
- Check purchase bills from suppliers — verify none are composition dealers.
- Calculate personal-use proportion for any dual-use expenses (mobile, internet).
- Update Blocked ITC Register with clause-wise breakdown for the month.
- Enter total blocked ITC in GSTR-3B Table 4(B)(1) before filing.
- Reconcile GSTR-3B blocked ITC with books of accounts.
Conclusion — Documentation & Classification Are Everything
Section 17(5) is one of the most litigated and scrutinized provisions under GST because it directly impacts the bottom line. Businesses must carefully identify the nature of each inward supply, verify HSN/SAC codes, assess usage purpose, and check whether any statutory exceptions apply before claiming ITC.
The key practical rules to remember:
- Section 17(5) is a non-obstante clause — it overrides Section 16. Even fully compliant supplies can be blocked.
- The list is exhaustive — if it's not in Section 17(5), ITC is generally available.
- Exceptions matter — always check whether the mandatory-use or further-supply exception applies before blocking ITC.
- Plant & Machinery is not immovable property — ITC on P&M procurement and installation is generally available.
- Maintain a clause-wise Blocked ITC Register — this is your first line of defence in any GST audit or scrutiny proceeding.
- Report correctly in GSTR-3B Table 4(B)(1) — never let blocked credit enter your Electronic Credit Ledger.
Incorrect ITC claims under blocked credits may result in ITC reversal with 24% interest, penalty proceedings, and departmental investigations. Periodic ITC review, proper documentation, and clause-wise classification are not optional — they are the foundation of GST compliance.
