What is Blocked Credit in GST? Section 17(5) Explained
- Blocked credit refers to ITC specifically disallowed under Section 17(5) of the CGST Act.
- ITC can be blocked even if the purchase is for business use.
- Common examples include cars with seating capacity up to 13 persons, employee food benefits, club memberships, construction of immovable property, CSR expenses, free samples, and goods written off.
- Section 17(5)(d) now uses “plant and machinery” instead of “plant or machinery” with retrospective effect from 1 July 2017.
- Section 17(5) now includes CSR-related inward supplies as blocked credit.
- Section 17(5)(i) now refers to tax paid under Section 74 only for periods up to FY 2023-24. References to Sections 129 and 130 have been removed.
- In GSTR-3B, blocked credit under Section 17(5) is reported in Table 4(B)(1).
- IMS acceptance does not make blocked credit eligible. If an invoice is accepted or deemed accepted in IMS but the expense is blocked under Section 17(5), the ITC should still be reversed in GSTR-3B Table 4(B)(1).
- In GSTR-9, Section 17(5) reversal should be reported in Table 7E, not Table 7A.
What is Blocked Credit Under GST?
Blocked credit under GST means input tax credit that a registered taxpayer cannot claim because the law specifically restricts it. Normally, ITC is available when goods or services are used for business, and the conditions of Section 16 are satisfied. But Section 17(5) overrides this general rule. It says that ITC shall not be available for the listed goods, services, or situations, even if they are used in the course or furtherance of business.
For example, if a company buys a car for the director's travel, GST may be paid on the vehicle. But if the car has an approved seating capacity of not more than 13 persons, ITC is blocked unless the business falls under a specific exception, such as further supply of vehicles, passenger transport, or driving training.

Why Does Blocked Credit Exist?
Blocked credit exists because GST ITC is meant for business-linked tax flow, not for personal consumption , employee perks, civil construction, or expenses where the law intentionally restricts credit.
The main idea is simple: GST should allow credit where the expense directly supports taxable outward supply , but not where the expense is personal in nature, welfare-oriented, non-business, capitalized into immovable property, or specifically restricted by law.
This is why a business may be able to claim ITC on raw material, packing material, accounting software , or office rent, but may not be able to claim ITC on a company car, employee gym membership, construction of an office building, or free samples.
Latest Updates Under Section 17(5)
1. “Plant or machinery” changed to “plant and machinery”
Section 17(5)(d) now refers to plant and machinery for the purpose of blocking ITC on construction of immovable property on own account. The law also clarifies that, despite any judgment or order, any reference to “plant or machinery” shall be deemed to mean “plant and machinery.”
This is important after the Safari Retreats case, where the difference between “plant or machinery” and “plant and machinery” had created an argument around the functionality test. After the retrospective amendment, the safer position is that ITC on construction of immovable property remains blocked unless the asset qualifies as plant and machinery under the GST explanation.
The GST explanation says plant and machinery means apparatus, equipment and machinery fixed to earth by foundation or structural support and used for making outward supply. It excludes land, buildings, civil structures, telecom towers and pipelines laid outside factory premises.
| Usually eligible if conditions are met | Usually blocked |
|---|---|
| Machinery fixed to earth for manufacturing | Factory building |
| Boiler, reactor, generator or production equipment | Office building |
| Conveyor system or installed production line | Boundary wall |
| Fixed cold storage plant used for taxable supply | Civil shed or warehouse structure |
| Foundation supporting qualifying machinery | Pipelines outside factory premises |

2. CSR expenses are specifically blocked
Section 17(5) includes clause (fa), which blocks ITC on goods or services used or intended to be used for CSR obligations under Section 135 of the Companies Act, 2013 . This means GST paid on CSR-related purchases should not be claimed as normal business ITC.
3. Section 74-related blocked credit is restricted up to FY 2023-24
Section 17(5)(i) now blocks ITC on tax paid under Section 74 only for periods up to FY 2023-24. The current wording no longer refers to Sections 129 and 130.
4. 56th GST Council rate changes do not change Section 17(5)
The 56th GST Council recommendations changed GST rates and related transition rules from 22 September 2025, but they did not introduce a new blocked credit category under Section 17(5). However, if an outward supply became exempt after the rate change, ITC reversal may be required under the normal CGST provisions. This should be treated as a separate ITC reversal issue, not as a new Section 17(5) blocked credit update.

Blocked Credit vs Ineligible ITC
Blocked credit and ineligible ITC are often used together, but they should not be treated as exactly the same in practical GST compliance . A practical way to understand it: blocked credit is a direct legal restriction. Other ITC issues may arise because a condition has not yet been met, or because ITC needs to be proportionately reversed.
| Point | Blocked credit | Other ineligible or reversible ITC |
|---|---|---|
| Main legal basis | Section 17(5) | Section 16 conditions, Rules 37, 37A, 42, 43, and other provisions |
| Nature | Specifically disallowed by law | May be temporary, condition-based, or apportionment-based |
| Example | Car ITC, CSR ITC, free samples | Supplier has not filed, goods not received, payment pending beyond 180 days |
| Can it become eligible later? | Usually no, unless an exception applies | Sometimes yes, if legal conditions are later met |
| GSTR-3B reporting | Table 4(B)(1) | Depends on the nature of the reversal |
| GSTR-9 reporting | Table 7E for Section 17(5) | Relevant table under 7A to 7H |

How to Report Blocked Credit in GSTR-3B
CBIC Circular No. 170/02/2022-GST explains that total ITC from GSTR-2B is auto-populated into Table 4(A) of GSTR-3B, and the registered person must identify ineligible ITC and reversals to arrive at net ITC. It also clarifies that ineligible ITC under Section 17(5) should be reported in Table 4(B)(1).
| GSTR-3B Table | What to report |
|---|---|
| Table 4(A) | Total ITC auto-populated from GSTR-2B |
| Table 4(B)(1) | Non-reclaimable reversal, including Section 17(5) blocked credit |
| Table 4(B)(2) | Temporary or other reversals that may be reclaimed later |
| Table 4(C) | Net ITC available after reversals |

What to report
Do not depend only on IMS, GSTR-2B, or portal auto-population to decide ITC eligibility . An invoice accepted or deemed accepted in IMS may flow into GSTR-2B and GSTR-3B, but the taxpayer must still check whether the expense is blocked under Section 17(5). If the invoice relates to food bills, car insurance, civil construction material, CSR purchases, or any other blocked category, reverse the ITC in GSTR-3B Table 4(B)(1).
How to Report Blocked Credit in GSTR-9
In GSTR-9 , Section 17(5) reversal should be reported in Table 7E. Table 7A is not for Section 17(5); it is for Rule 37 reversal. This correction is important because reporting Section 17(5) blocked credit in the wrong GSTR-9 table can create reconciliation issues during annual return review.
| GSTR-9 Table | Use |
|---|---|
| 7A | Rule 37 reversal |
| 7B | Rule 39 |
| 7C | Rule 42 |
| 7D | Rule 43 |
| 7E | Section 17(5) blocked credit |
| 7H | Other reversals |

Common Mistakes to Avoid
- Don’t claim ITC just because the invoice has GST. It does not automatically make ITC eligible. The expense must pass Section 16 conditions and must not fall under Section 17(5).
- Don’t treat every business expense as eligible. Some expenses are clearly business-related but still blocked. A company car, office building or CSR purchase may support the business, but the law can still deny ITC.
- Don’t ignore CSR classification. CSR ITC should be reviewed separately because Section 17(5)(fa) now specifically excludes goods and services used for CSR obligations.
- Do not report Section 17(5) reversal in Table 7A. Use Table 7E.
- Try to avoid writing 24% interest as automatic without checking the notified rate and period. Interest under Section 50(3) applies where ITC is wrongly availed and utilised. Rule 88B explains how the period of utilization is determined.
- Don’t treat IMS acceptance as final ITC eligibility. Accepting an invoice in IMS only helps decide whether it flows into GSTR-2B and GSTR-3B. It does not override Section 17(5). If the expense is blocked, reverse it even if the invoice appears as available ITC .
Monthly Blocked Credit Checklist
- Review GSTR-2B and the purchase register before filing GSTR-3B.
- Review accepted and deemed-accepted IMS invoices before filing GSTR-3B to check whether any credit is blocked under Section 17(5).
- Check vehicle, insurance, repair, and maintenance expenses.
- Separate food, catering, employee welfare, and club membership invoices.
- Review construction, renovation, and capitalization entries.
- Identify CSR-related purchases separately.
- Check goods lost, destroyed, written off, gifted, or issued as free samples.
- Confirm whether any statutory exception applies before claiming ITC.
- Report Section 17(5) blocked credit in GSTR-3B Table 4(B)(1).
- Maintain a blocked credit register with invoice number, vendor, GST amount, clause reference and reason for reversal.
- Reconcile annual Section 17(5) reversals with GSTR-9 Table 7E.
Conclusion
Blocked credit under GST is not a minor accounting adjustment. It directly affects ITC eligibility, working capital , monthly return accuracy and annual reconciliation.
The safest approach is to review every doubtful invoice against Section 17(5), instead of assuming that business use alone makes ITC available. Special attention should be given to vehicles, food and employee benefits, construction, CSR expenses, free samples, written-off goods and tax paid under fraud-related proceedings.
In practice, three points deserve careful attention: CSR purchases should be reviewed against Section 17(5)(fa) before claiming ITC; Section 17(5) reversals belong in GSTR-9 Table 7E, not Table 7A; and interest on wrongly availed blocked credit should be calculated under Section 50(3) and Rule 88B, not assumed at 24% without checking.
