In-Depth Analysis of Input Tax Credit under the GST Act: Section 17 – Apportionment of Credit and Blocked Credits
Section 17 of the GST Act details conditions for Input Tax Credit (ITC) apportionment and specifies ‘blocked credits’ where ITC cannot be claimed. When goods or services are used partly for business and partly for non-business purposes, ITC is limited to the business portion. Similarly, for supplies used for both taxable (including zero-rated) and exempt purposes, ITC is restricted to the taxable and zero-rated portion. The value of exempt supplies for this calculation includes reverse charge supplies, securities transactions, and sales of land or building, but generally excludes activities listed in Schedule III. Banking companies and NBFCs have an option: either follow the general apportionment rules or claim a flat 50% of eligible ITC monthly, with the remainder lapsing, an option that cannot be changed during the financial year and doesn’t apply to inter-branch transfers with the same PAN. Furthermore, Section 17(5) specifically blocks ITC on certain items, including most motor vehicles, vessels, and aircraft (unless used for further supply, passenger transport, or training), along with their related insurance, servicing, and repairs. ITC is also disallowed for food and beverages, outdoor catering, beauty treatments, health services, club memberships, and employee travel benefits (unless legally mandated). Works contract services for immovable property (excluding plant/machinery) and goods/services used for self-construction of immovable property are also blocked. Additionally, ITC is unavailable for goods/services under the Composition Scheme, those received by non-resident taxable persons (except imports), goods/services used for Corporate Social Responsibility (CSR), personal consumption, or items lost, stolen, destroyed, written off, gifted, or provided as free samples. Tax paid under Section 74 for periods up to FY 2023-24 is also a blocked credit.

Respected Sir,
Subject: Summary of Amendment to Section 17(5)(d), CGST Act – Finance Act, 2025
Provision Overview:
Section 17(5)(d) of the CGST Act restricts ITC on goods/services used for the construction of immovable property (other than plant and machinery) on own account, even if used in the course of business.
Amendment: The Finance Act, 2025 (retrospective from 01.07.2017) substitutes “plant and machinery” with “plant or machinery”.
Impact:
Before: ITC was disallowed only if the construction excluded both plant and machinery (i.e., ITC allowed if either was involved).
After: ITC is disallowed even if construction relates to only plant or only machinery, if done on own account.
The amendment broadens the scope of blocked credit and applies retrospectively, impacting ITC claims since 01.07.2017.
Thank you.
