GST Blocked Credit Reference: Section 17(5) in Plain Language
Not all GST paid on purchases can be claimed as input tax credit. Section 17(5) of the CGST Act blocks credit for certain categories even when the expense relates to business. This table gives manufacturers and finance teams a quick reference.
| Category | Credit blocked for | Main exception | Reference | ERP and booking tip |
|---|---|---|---|---|
Motor vehicles for carrying 13 persons or fewer (including driver) | Purchase, hire, repair, insurance and related inputs | Supplier of vehicles, transport of passengers, driving school or similar business use of that vehicle | Section 17(5)(a) | Tag vehicle expenses by vehicle class in fixed asset and expense masters. |
Vessels and aircraft | Purchase, hire and related inputs | Supply of vessels or aircraft, transport of passengers or goods, training | Section 17(5)(aa) | Check the business use before posting. |
Food and beverages | Credit on food, beverages and outdoor catering | Where the outward supply is of the same category, or mandatory under law for employees | Section 17(5)(b) | Use a separate GL for staff canteen and a different one for client hospitality. |
Beauty treatment, health services, cosmetic and plastic surgery | Services of this kind | Where the outward supply is of the same category or mandatory by law | Section 17(5)(b) | Rare for manufacturers, but check wellness reimbursements. |
Membership of a club, health and fitness centre | Membership fees | None for ordinary business use | Section 17(5)(b) | Post to a non-creditable account. |
Travel benefits to employees on vacation (leave or home travel concession) | Cost of such benefits | None | Section 17(5)(b) | Separate HR travel from business travel. |
Works contract services for construction of an immovable property | Services other than plant and machinery | Where the output is also works contract service for construction | Section 17(5)(c) | Split plant and machinery from civil work in capital projects. |
Goods or services for construction of immovable property on own account | Inputs such as cement and steel, used for own building | Plant and machinery | Section 17(5)(d) | Use asset class and project codes to separate plant from building. |
Goods or services used for personal consumption | Personal use items | None | Section 17(5)(g) | Block through expense approval rules. |
Goods lost, stolen, destroyed, written off or given as gifts or free samples | Credit on such goods | None | Section 17(5)(h) | Trigger a reversal from the inventory write-off transaction. |
Tax paid under Sections 74, 129 and 130 | Tax paid after detention, seizure or fraud findings | None | Section 17(5)(i) | Post to a separate non-creditable GL. |
Inputs used for exempt supplies | Proportionate credit | None | Section 17(2) and Rule 42 | Not part of 17(5), but also needs an apportionment and reversal. |
Inputs used partly for business and partly for other purposes | Portion for non-business use | None | Section 17(1) | Use a fixed allocation rule and document it. |
Credit not shown in GSTR-2B or not supported by a valid invoice | Credit until conditions are met | Conditions in Section 16 | Section 16(2) | Run the monthly 2B matching before claiming. |
Summary reference. Wording and exceptions in Section 17(5) have been amended over time, and some entries need context. Read the section and any current notification before reversing or claiming credit.

How to use this reference
Search for the kind of expense, such as vehicles, food, memberships or construction, and read the exception column. The exceptions matter because the rule is often narrower than people think. For example, motor vehicle credit is blocked in general but allowed when the vehicle is used to carry out a taxable supply of vehicles or transport. Use the tip column to decide how to flag expense accounts and fixed asset classes in your ERP. Export to Excel to attach to your AP policy.
Why the blocked list exists
GST allows credit on inputs used in the course or furtherance of business. The law then removes certain items where personal consumption is likely or where the cost relates to immovable property. Credit is also available only if the conditions of Section 16 are met, which means a valid tax invoice, receipt of goods or services, the tax being paid by the supplier, and the return being filed. Blocked credit should be reported as ineligible in GSTR-3B rather than claimed and reversed later.
- Section 17(5) lists blocked categories
- Section 16 sets conditions for eligible credit
- Rule 42 and 43 apportion credit on exempt supplies
- Ineligible credit is reported separately in GSTR-3B
Common mistakes
Companies often claim credit on staff food, employee gifts and company cars because the vendor invoice shows GST. Others miss that goods destroyed or written off require a reversal. Capital projects are a frequent trouble spot because plant and machinery is eligible but the building around it is not, and the invoice may bundle both. Build review rules into vendor invoice approval so these items are tagged before posting.
ERP notes
In SAP, Oracle, Dynamics, Tally and Busy, the cleanest approach is a separate non-creditable tax code or tax rule for blocked categories, assigned by GL account. For write-offs and scrap, tie the reversal to the inventory transaction so the finance team does not depend on memory. Report the blocked credit monthly so it can be compared with the figure reported as ineligible in the return.
Frequently Asked Questions
Is ITC on motor vehicles allowed?
In general no, if the vehicle is designed to carry 13 persons or fewer including the driver. It is allowed when the vehicle is used for further supply of such vehicles, passenger transport, or driver training. Vehicles for goods transport are outside this block.
Can I claim ITC on staff canteen food?
Generally no, because food and beverages are blocked. An exception applies where providing the food is mandatory under law, such as a factory canteen requirement, and the credit position should be reviewed for that case. Many companies claim it only with proper legal support.
Is ITC allowed on plant and machinery?
Yes, plant and machinery is not blocked even when it is installed on land. The block relates to buildings and civil structures. Separate the costs in the purchase order and invoice so the creditable portion is clear.
How is blocked credit reported in the return?
Ineligible credit is shown in the ITC section of GSTR-3B under the relevant ineligible lines, such as ITC under Section 17(5). If you claimed it earlier by mistake, you must reverse it with interest in line with the rules.
Netray can help build a read-only report of creditable versus non-creditable GST by account, so the figure in your return can be tied back to the ledger.
