GST ITC on capital goods — availment, reversal and useful-life rules 2026

GST ITC on Capital Goods: Availment, Reversal and Useful-Life Rules in 2026

Introduction

Under the Goods and Services Tax (GST) regime, businesses can claim Input Tax Credit (ITC) on eligible capital goods used or intended to be used in the course or furtherance of business. However, claiming ITC on capital goods is subject to specific conditions, restrictions and reversal provisions.

One of the most important concepts is the five-year useful-life rule prescribed under Rule 43 of the CGST Rules for capital goods that are used commonly for taxable and exempt supplies.

This article explains the key rules relating to availment, reversal, sale and useful life of capital goods under GST in 2026.

What are Capital Goods under GST?

Under GST, capital goods generally mean goods whose value is capitalised in the books of account of the person claiming ITC and which are used or intended to be used in the course or furtherance of business.

Examples may include:

Machinery and equipment

Computers and servers

Factory equipment

Furniture and office equipment

Certain plant and machinery

Other business assets eligible for ITC

However, merely capitalising an asset in the books does not automatically make its GST credit eligible. The normal conditions and restrictions for claiming ITC must also be satisfied.

When can ITC on Capital Goods be Availed?

A registered person can claim ITC on eligible capital goods when the conditions prescribed under Section 16 of the CGST Act are fulfilled.

Broadly, the following points should be checked:

The recipient should have a valid tax invoice or prescribed tax document.

The goods should have been received.

The capital goods should be used or intended to be used for business purposes.

The applicable GST should be eligible for ITC and not blocked under Section 17(5).

The credit should be reflected/eligible as per the applicable GST provisions.

The recipient should comply with the applicable return and payment conditions.

Section 16 provides the basic entitlement to ITC on supplies used or intended to be used in the course or furtherance of business.

Is Full ITC Available on Capital Goods?

Yes, eligible ITC on capital goods can generally be claimed upfront, subject to the GST provisions.

There is an important distinction between:

Availing ITC, and

Reversal of ITC

The five-year rule under Rule 43 does not mean that ITC must normally be claimed in five equal instalments.

For capital goods that are commonly used for taxable and exempt supplies, Rule 43 provides a mechanism to determine the portion attributable to exempt supplies over the useful life of the capital goods.

Useful Life of Capital Goods under GST

For the purpose of Rule 43, the useful life of capital goods is considered as 5 years or 60 months from the date of invoice.

Therefore:

Useful Life = 5 Years = 60 Months

For common capital goods, the monthly ITC attributable to the asset is determined by dividing the common credit by 60.

Formula

Tm = Tc ÷ 60

Where:

Tc = Common credit relating to capital goods

Tm = ITC attributable to a tax period

The CGST Rules specifically provide that the useful life of capital goods for this purpose is five years from the date of invoice.

ITC Reversal When Capital Goods are Used for Exempt Supplies

If capital goods are used partly for taxable supplies and partly for exempt supplies, the applicable proportion of ITC attributable to exempt supplies is required to be reversed.

Under Rule 43, the amount attributable to exempt supplies is calculated using:

Te = (E ÷ F) × Tr

Where:

Te = ITC attributable to exempt supplies

E = Aggregate value of exempt supplies

F = Total turnover

Tr = Common ITC attributable to capital goods during the relevant period

The amount attributable to exempt supplies is added to the output tax liability during the residual useful life of the capital goods.

Example of Capital Goods ITC Reversal

Suppose a company purchases machinery for:

GST paid = ₹1,20,000

The machinery is used commonly for taxable and exempt supplies.

The useful life under Rule 43 is:

60 months

Therefore:

Monthly common credit = ₹1,20,000 ÷ 60 = ₹2,000

Suppose during a particular month:

Exempt turnover = ₹2,00,000

Total turnover = ₹10,00,000

Then:

Exempt turnover ratio = 2,00,000 ÷ 10,00,000 = 20%

Therefore:

ITC reversal = ₹2,000 × 20% = ₹400

Thus, ₹400 would be attributable to exempt supplies for that tax period, subject to the applicable Rule 43 mechanism.

What Happens When Capital Goods are Used Exclusively for Taxable Supplies?

If eligible capital goods are used exclusively for making taxable supplies, including zero-rated supplies, the applicable ITC can generally be credited without applying the common-credit reversal mechanism for exempt supplies.

On the other hand, capital goods used exclusively for non-business purposes or exclusively for exempt supplies are not eligible for such credit under the relevant Rule 43 treatment.

What if Capital Goods are Later Used for Exempt Supplies?

The treatment can change if the use of capital goods changes.

For example:

A machine was initially used exclusively for taxable supplies. Later, the machine starts being used commonly for taxable and exempt supplies.

In such a case, Rule 43 provides a mechanism for determining the eligible common credit after considering the period for which the capital goods were previously covered under the relevant category.

The rules also provide for reduction at 5 percentage points for every quarter or part thereof in specified situations.

Reversal When Business Becomes Composition or Supply Becomes Exempt

A registered person may have to reverse/pay an amount relating to ITC on capital goods where:

The person opts for composition taxation, or

The supplies of the person become wholly exempt.

Section 18(4) provides for payment of an amount relating to ITC on capital goods, reduced by the prescribed percentage points, subject to the applicable provisions.

For capital goods, Rule 44 provides a remaining useful-life approach, with the useful life considered as five years.

Example

Suppose:

ITC availed on machinery = ₹1,00,000

Machinery has been used for 3 years

Remaining useful life = 2 years = 24 months

The credit attributable to the remaining period would be determined proportionately:

₹1,00,000 × 24 ÷ 60 = ₹40,000

The applicable reversal/payment would then be determined according to the relevant provisions.

What Happens When Capital Goods are Sold?

When capital goods or plant and machinery on which ITC has been availed are supplied/sold, Section 18(6) becomes important.

The registered person is required to pay the higher of:

ITC originally availed reduced by the prescribed percentage points, or

GST calculated on the transaction value of the capital goods

The applicable tax liability has to be determined according to the provisions of Section 18(6).

Simple Example

Suppose:

ITC availed on machinery = ₹1,00,000

Machinery is sold after some period

GST on transaction value = ₹45,000

Amount calculated after prescribed reduction = ₹50,000

In this case, the higher amount, i.e. ₹50,000, would be relevant for the Section 18(6) payment, subject to the applicable provisions.

Capital Goods Sent for Job Work

ITC on eligible capital goods is not automatically lost merely because the capital goods are sent to a job worker.

Section 19 provides specific provisions allowing the principal to claim ITC on capital goods sent for job work, subject to the prescribed conditions.

Capital goods generally need to be brought back or supplied within the prescribed period. For capital goods, the relevant period under Section 19 is generally three years from the date of being sent out, subject to the statutory provisions.

Blocked ITC on Certain Capital Goods

Not every capital asset automatically qualifies for ITC.

Businesses must also check the restrictions under Section 17(5).

For example, certain goods or services relating to:

Motor vehicles, subject to specified exceptions

Construction of immovable property

Personal consumption

Goods lost, stolen, destroyed or written off

Gifts or free samples

may be subject to blocked-credit provisions.

Therefore, the accounting treatment of an item as a capital asset does not by itself establish GST ITC eligibility.

Important Difference: Income Tax Depreciation vs GST Useful Life

One common confusion among taxpayers is whether the GST five-year useful life must match the depreciation period under the Income-tax Act.

It does not necessarily work that way.

The 5-year / 60-month useful-life rule under GST is a specific mechanism under the CGST Rules, particularly for Rule 43 calculations.

The accounting depreciation or Income-tax depreciation period of an asset may be different.

Therefore, businesses should separately consider:

Accounting depreciation

Income-tax depreciation

GST ITC eligibility

GST reversal under Rule 43/44

GST liability on sale of capital goods

Key Points to Remember in 2026

For practical GST compliance, businesses should remember the following:

Eligible ITC on capital goods can generally be availed subject to Section 16 conditions.

Capital goods used commonly for taxable and exempt supplies are subject to Rule 43 reversal.

GST useful life for the Rule 43 mechanism is 5 years / 60 months from the date of invoice.

The monthly common-credit amount is determined using the Tc ÷ 60 formula.

Exempt-use proportion may have to be reversed during the residual useful life.

Special reversal/payment provisions apply when a taxpayer opts for composition or supplies become wholly exempt.

Sale of capital goods on which ITC was availed is governed by Section 18(6).

ITC on capital goods may be blocked under Section 17(5) depending on the nature and use of the asset.

Job-work movement of capital goods has specific time limits and compliance requirements.

GST useful life and accounting/income-tax depreciation should not be confused.

Conclusion

GST ITC on capital goods can provide significant tax savings for businesses, but the credit must be claimed and monitored carefully. The five-year useful-life rule is particularly important where capital goods are used for both taxable and exempt supplies or where ITC reversal is required in special circumstances.

Businesses should maintain proper records of the invoice date, ITC claimed, date of use, taxable/exempt usage, remaining useful life and any subsequent sale or change in use of capital goods.

Proper tracking of these details helps avoid incorrect ITC claims, unnecessary reversals, interest exposure and GST compliance issues.
