Many businesses purchase corporate cars for executive travel, client visits, or general office administration. When the annual motor insurance premium or a garage repair invoice arrives with 18% or 28% GST, finance teams often wonder whether this tax qualifies for input tax credit. Because the expenditure is incurred wholly in the course or furtherance of business, accountants sometimes assume it is creditable under the general rules of Section 16(1). However, the statutory block under Section 17(5) overrides Section 16(1).
The statutory rule under Section 17(5)(ab)
Under Section 17(5)(a) of the CGST Act, input tax credit is blocked on motor vehicles designed for transportation of persons having an approved seating capacity of not more than thirteen persons, including the driver. This covers virtually all standard passenger cars, sedans, hatchbacks, and SUVs.
To prevent taxpayers from circumventing the vehicle purchase block by claiming running costs, Section 17(5)(ab) of the CGST Act specifically blocks credit on:
- Services of general insurance relating to such motor vehicles
- Servicing of such motor vehicles
- Repair and maintenance of such motor vehicles
This means if credit on the purchase of the car is blocked under Section 17(5)(a), credit on its insurance premium and repair bills is automatically blocked under Section 17(5)(ab). For a complete overview of all restrictions under this section, review our guide on blocked credit under GST Section 17(5) list with examples.
Common mistake: Claiming GST on routine car maintenance invoices simply because the invoice bears the company GSTIN and appears in Form GSTR-2B. Availing blocked credit leads to audit demands with mandatory 18% annual interest under Section 50(3) if utilised.
Exceptions where ITC on car repair and insurance is allowed
The proviso to Section 17(5)(ab) creates narrow exceptions where input tax credit on insurance, servicing, and repair of such passenger vehicles is legally admissible:
- Vehicles used for specified taxable purposes: Where the underlying motor vehicle itself qualifies for credit under the exceptions listed in Section 17(5)(a):
- Making a further taxable supply of such motor vehicles (car dealerships).
- Transportation of passengers (commercial passenger transport, taxi operators).
- Imparting training on driving such motor vehicles (driving schools).
- Vehicle manufacturers: Where the services of insurance, servicing, repair, and maintenance are received by a registered person engaged in the manufacture of such motor vehicles.
- General insurance providers: Where such services are received by a registered person engaged in the supply of general insurance services in respect of such motor vehicles.
Outside these statutory exceptions, an ordinary commercial trading entity, IT consulting firm, manufacturing plant, or professional services firm cannot claim ITC on car repair or insurance for staff cars.
Worked example: corporate car repair versus taxi fleet
Consider two companies operating in Maharashtra that each incur vehicle repair and insurance expenses during October 2026. ABC Advisors Private Limited runs a management consultancy and maintains two corporate cars for executive travel. FastTrack Mobility LLP operates a commercial passenger taxi fleet.
Each business receives two tax invoices during the month:
- Invoice 1: Annual comprehensive motor insurance premium of ₹50,000 plus 18% GST (₹9,000).
- Invoice 2: Accidental body repair and servicing of ₹1,00,000 plus 18% GST (₹18,000).
| Company | Vehicle usage | Taxable value | GST charged | Section | Admissible ITC |
|---|---|---|---|---|---|
| ABC Advisors Pvt Ltd | Executive travel (13 or fewer seats) | ₹1,50,000 | ₹27,000 | Section 17(5)(ab) | ₹0 (Blocked) |
| FastTrack Mobility LLP | Passenger transport business | ₹1,50,000 | ₹27,000 | Proviso to s.17(5)(ab) | ₹27,000 (Eligible) |
For ABC Advisors Pvt Ltd, the total GST of ₹27,000 (₹9,000 insurance + ₹18,000 repair) is blocked credit. The tax must be added to the repair and insurance expense in the profit and loss statement rather than claimed as an offset against output GST liability.
How to report blocked vehicle expenses in Form GSTR-3B
When the garage or insurance company files its GSTR-1, the tax invoice auto-populates into your Form GSTR-2B. Under the reporting mechanism clarified in CBIC Circular No. 170/02/2022-GST and the GSTN manual for Form GSTR-3B, you handle this credit through the following workflow:
- Table 4(A)(5) (All other ITC): The total tax of ₹27,000 automatically enters Table 4(A)(5) as part of your gross inward supplies from GSTR-2B. Do not reduce the auto-populated number in Table 4(A)(5).
- Table 4(B)(1) (As per rules 38, 42 and 43 and section 17(5)): Enter ₹27,000 in Table 4(B)(1). This reflects an absolute, permanent reversal that cannot be reclaimed in any future tax period.
- Table 4(C) (Net ITC available): The portal calculates Net ITC as 4(A) minus 4(B). The ₹27,000 is deducted, ensuring zero blocked credit flows into your Electronic Credit Ledger.
If ABC Advisors Pvt Ltd instead left the ₹27,000 in Table 4(A)(5) without entering the reversal in Table 4(B)(1), and subsequently utilised the balance to discharge outward tax liability, the company would be liable under Section 50(3) to repay the tax with 18% annual interest calculated from the date of utilisation to the date of reversal.
Frequently asked questions
Can a business claim ITC on car insurance if the vehicle is registered in the company name?
No. Even if the car is owned by the business and used exclusively for company directors or staff, input tax credit on insurance, servicing, and repairs remains blocked under Section 17(5)(ab) unless the vehicle is used for an excepted commercial purpose such as transportation of passengers or driving training.
Where should blocked car repair ITC be reported in Form GSTR-3B?
Per CBIC Circular No. 170/02/2022-GST, all inward supplies appearing in GSTR-2B enter Table 4(A)(5), and blocked credit under Section 17(5) is permanently reversed in Table 4(B)(1).
Is GST on repair of commercial trucks or goods transport vehicles eligible for ITC?
Yes. The block under Section 17(5)(a) and Section 17(5)(ab) applies to motor vehicles for transportation of persons with approved seating capacity of up to thirteen persons. Goods transport vehicles like trucks or delivery vans do not fall under this restriction, so repair and insurance ITC on goods vehicles is eligible.
