Section 17 – Apportionment of Input Tax Credit and Blocked Credits (CGST Act, 2017)

Section 17 lays down how Input Tax Credit (ITC) must be restricted, apportioned, or fully blocked when goods or services are used for multiple purposes. These include situations where inputs are used for both taxable and exempt supplies, or for both business and non-business activities. The section also specifies ineligible credits, defines the scope of exempt supply only for reversal purposes, provides special rules for the banking sector, and connects to Rule 42 (inputs and input services) and Rule 43 (capital goods) for reversing ITC proportionately.

Section 17(1) – ITC Restricted to Business Use

This clause sets the fundamental principle that ITC is permissible only when goods or services are used in the course or furtherance of business. Whenever an input has mixed use – partly for business and partly for personal or non-business purposes – only the business-use portion is eligible. The method of apportionment is governed by Rule 42 for inputs and input services and Rule 43 for capital goods. This ensures that taxpayers do not claim credit toward personal consumption or private benefits.

Key Highlights

• ITC is allowed only for business use and not for personal or non-business consumption.
• Mixed use of goods/services requires proportionate ITC reversal for the non-business portion.
• Rule 42 applies to inputs and input services having mixed business and personal usage.
• Rule 43 applies to capital goods partly used for business and personal purposes.
• Documentary evidence of business use is mandatory for ITC eligibility.

Example

A consultant buys a mobile phone with GST ITC of Rs. 9,000 and uses it 60 percent for office calls and 40 percent for personal use. Only Rs. 5,400 (60 percent) is eligible for ITC, and Rs. 3,600 must be reversed under Rule 42 because it represents personal consumption.

Section 17(2) – ITC Allowed Only for Taxable and Zero-Rated Supplies

This clause applies when a taxpayer makes both taxable/zero-rated supplies and exempt supplies. ITC is allowed only to the extent used for taxable or zero-rated activities. ITC relating to exempt activities must be reversed. When common inputs or services are used for both categories, apportionment must be done based on Rule 42 (inputs/services) and Rule 43 (capital goods). Monthly reversal and annual adjustment are mandatory.

Key Highlights

• ITC cannot be claimed for inputs or services used for exempt supplies.
• ITC relating to taxable and zero-rated supplies remains fully eligible.
• Common ITC must be divided based on the turnover ratio using Rule 42 (for inputs/services) and Rule 43 (for capital goods).
• Exempt turnover includes certain non-taxable and Schedule III activities for reversal purposes.
• Annual reconciliation is compulsory to align monthly reversals with actual annual turnover.

Example

If a business has total turnover of Rs. 80 lakh, where Rs. 20 lakh is exempt supply and Rs. 60 lakh is taxable supply, and the common ITC for the month is Rs. 40,000, then 25 percent of ITC (Rs. 10,000) must be reversed and the remaining Rs. 30,000 is eligible.

Section 17(3) – Scope of Exempt Supply for Reversal

Section 17(3) expands the meaning of exempt supply specifically for the purpose of ITC reversal. It includes transactions that are normally non-taxable, outside GST, or treated as no-supply under Schedule III. This broader definition ensures that all income streams not subject to GST are considered while calculating reversal, thereby increasing the exempt proportion and reducing eligible ITC.

Key Highlights

• Non-GST goods like alcohol for human consumption are included as exempt supply.
• Schedule III activities such as salary, sale of land, and sale of completed buildings are counted for reversal.
• Residential dwelling rented for residential use is included as exempt turnover.
• Interest income on loans, deposits, debentures, securities, and advances forms part of exempt turnover.
• Sale of completed building after completion certificate is included for reversal purposes.
• Sale of securities is valued at 1% of sale value for turnover computation (Rule 42 Explanation).

Example

If a company earns Rs. 10 lakh from taxable operations and Rs. 5 lakh from interest on fixed deposits, then while calculating ITC reversal, the Rs. 5 lakh interest must be added as exempt turnover even though it is not taxable under GST. This increases the exempt ratio and consequently increases the amount of common ITC to be reversed.

Section 17(4) – Special Option for Banking and NBFC Sector

Banks, NBFCs, and financial institutions deal mainly in exempt interest transactions, making Rule 42 and Rule 43 extremely complex. Section 17(4) provides an optional method where such entities can avail only 50% of total eligible ITC in a tax period and permanently forgo the remaining 50%. This option applies to inputs, input services, and capital goods and continues for the entire financial year once chosen.

Key Highlights

• Applicable to Banks, NBFCs, and other Financial Institutions.
• Fifty percent of eligible ITC can be availed, while the remaining fifty percent is permanently lapsed.
• Applies to inputs, input services, and capital goods uniformly.
• Option is irrevocable for the entire financial year.
• No proportionate reversal under Rule 42 or Rule 43 is required once this option is chosen.

Example

If a bank receives a total ITC of Rs. 6,00,000 in a month, it may avail only Rs. 3,00,000 under this scheme. The remaining Rs. 3,00,000 cannot be claimed at any stage and is treated as permanently ineligible.

Section 17(5) – Blocked Credits (Ineligible ITC)

Section 17(5) lists goods and services where ITC is legally disallowed, regardless of whether they are used for business purposes. These blocked credits override the general eligibility under Section 16. The intent is to prevent ITC benefits on personal consumption, immovable property construction, employee welfare activities, and similar non-core business expenditures.

Major Blocked Credits

• Motor vehicles (≤13 seats) unless used for passenger transport, training, or outward supply of vehicles.
• Food, beverages, and outdoor catering unless used for outward supply of the same category.
• Beauty treatment, health services, and cosmetic surgery unless outwardly supplied.
• Membership of clubs, gyms, or sports facilities.
• Rent-a-cab, life insurance, and health insurance unless mandated by law or supplied outwardly.
• Employee travel benefits like LTA, LTC, or holiday packages.
• Works contract services for constructing immovable property except for plant and machinery.
• Goods or services used to construct immovable property on own account.
• ITC on goods lost, stolen, destroyed in fire, written off, gifted, or given as free samples.
• ITC on telecommunications towers and pipelines laid outside factory premises (treated as immovable property).
• ITC against tax paid under the Composition Scheme.

Example

If a company purchases gym membership for its employees as part of a wellness programme, ITC on the membership fee is blocked under Section 17(5) and cannot be claimed, even though the company incurs the expense for employee welfare.

Link with Rule 42 and Rule 43

Rule 42 – Inputs and Input Services

Rule 42 prescribes the formula for reversing ITC on inputs and input services used for both taxable and exempt activities. It includes proportionate turnover-based calculation, a 5% deemed non-business reversal on common credits, monthly adjustments, and mandatory year-end reconciliation.

Rule 43 – Capital Goods

Rule 43 applies to capital goods and spreads their credit over 60 months, calculating the amount attributable to exempt supplies based on turnover. The apportioned amount must be reversed each month, with year-end adjustments.
