ITC on Capital Goods under GST — Rules, Restrictions, and Common Mistakes

How input tax credit on capital goods works under GST, when it must be reversed, and the operational mistakes that lead to demand notices.

Input tax credit (ITC) on capital goods is one of the areas in GST where the rules are spread across multiple sections and rules of the CGST Act and Rules — making it easy to miss conditions and end up with reversals that could have been avoided.

This article explains the framework for claiming ITC on capital goods, the situations where the credit must be reversed, and the common mistakes that lead to GST scrutiny.

What counts as capital goods under GST

Section 2(19) of the CGST Act defines capital goods as goods, the value of which is capitalised in the books of account of the person claiming the input tax credit and which are used or intended to be used in the course or furtherance of business.

The definition has two important elements: capitalisation in the books, and use in the furtherance of business. An item expensed in the P&L is an input, not a capital good, regardless of its physical nature. An item capitalised but never used for business purposes does not qualify for ITC at all.

The basic eligibility

ITC on capital goods is available in full in the month of receipt of the capital good, provided:

• The supplier has paid the tax to the Government (verifiable through GSTR-2B)
• The recipient has received the capital goods (physical receipt or constructive receipt)
• The recipient has a valid tax invoice
• The recipient is using or intends to use the capital good in the furtherance of business and for making taxable supplies, including zero-rated supplies

Unlike some indirect tax regimes that spread the credit over multiple periods, GST allows the full credit upfront on capital goods, subject to the conditions above.

When the credit must be reversed

There are several situations where the upfront credit needs to be partially or fully reversed:

• Use for exempt supplies under Rule 43 — where the capital good is used for both taxable and exempt supplies, the credit is allowed only to the extent of taxable use. The reversal is computed monthly for sixty months from the date of invoice, based on the ratio of exempt to total turnover for the period
• Personal or non-business use — credit attributable to non-business use must be reversed; for mixed-use goods the proportion is determined and reversed monthly under Rule 43
• Sale or transfer of the capital good — Section 18(6) requires payment of either the ITC reduced by five per cent per quarter of use from the date of invoice, or the GST on the transaction value, whichever is higher
• De-registration or cancellation of registration — ITC on capital goods on hand is to be reversed on the basis of useful life of five years from invoice date
• Composition scheme migration — full credit on capital goods on hand must be reversed
• Capital goods used exclusively for exempt supplies — no ITC at all is available, even temporarily

Common mistakes that cause demand notices

• Treating capital goods as inputs — capital goods have a sixty-month life for Rule 42 or 43 computation; treating them as inputs uses the wrong period and over-claims the credit
• Missing the Rule 43 monthly computation — businesses with both taxable and exempt supplies frequently overlook the monthly reversal requirement, leading to cumulative demand
• Section 18(6) on disposal — selling old equipment without computing the reversal under Section 18(6); the GSTR-1 disclosure must reflect the higher of the two amounts
• Capital work-in-progress — credit on inputs going into CWIP is governed by the rules applicable to capital goods (since the asset is being capitalised), not inputs
• Plant and machinery used for construction of immovable property — Section 17(5)(d) blocks credit on inputs and input services used for construction of immovable property, but capital goods used in the construction process may be allowable subject to the plant-and-machinery exception. The line between blocked and allowable is heavily litigated

ITC on motor vehicles

Section 17(5) blocks ITC on motor vehicles for the transportation of persons, with specific exceptions:

• Vehicles with seating capacity of more than thirteen persons including driver
• Vehicles used for further supply of such vehicles (i.e., a dealer)
• Vehicles used for transportation of passengers (i.e., a taxi or cab service)
• Vehicles used for imparting training on driving such vehicles

Motor vehicles for transportation of goods are not within the blocked category — ITC on a truck or a tempo is available.

Documentation requirements

For capital goods on which ITC has been availed, the following records should be maintained:

• Tax invoice from the supplier
• Proof of payment to the supplier (since payment is a precondition for retention of credit beyond 180 days under Section 16(4))
• Capitalisation entry in the books of account
• Asset register entry with date of put-to-use, location, and assignment
• For shared-use capital goods, the basis of attribution between taxable and exempt supplies

For disposal of capital goods, additional documentation is required, including the Section 18(6) computation, the determination of useful life used and useful life remaining, and the higher of ITC reduced by five per cent per quarter, or GST on transaction value.

A reconciliation tip

For businesses with significant capital expenditure, a quarterly reconciliation between the asset register and the ITC ledger is a useful control. The reconciliation should match asset additions in the quarter (from the books), capital goods on which ITC has been availed (from GSTR-3B and the working file), and capital goods on which ITC has been reversed under Rule 43, Section 18(6), or other provisions.

Differences typically arise from timing (invoice received but goods not yet received), errors in classification, or missed reversals. Catching them quarterly is much cheaper than discovering them in a GST audit.
