What Businesses Need to Know

When a business sells a fixed asset on which Input Tax Credit (ITC) was availed, a common question arises: Does the business have to reverse the entire ITC originally claimed, or is GST payable only on the sale?

The answer is neither as simple as “reverse the ITC” nor “pay GST on the sale.” The GST law contains a specific mechanism under Section 18(6) of the CGST Act, 2017, which deals with the tax consequences when capital goods or plant and machinery are supplied after ITC has been availed.

What Happens When a Business Sells a Fixed Asset?

Consider a company that purchases machinery for ₹10 lakh plus GST of ₹1.80 lakh and claims the entire eligible ITC. After using the machinery for three years, the company sells it for ₹5 lakh.

At this stage, there are effectively two GST considerations: GST applicable on the outward supply of the machinery, and the amount required to be paid under Section 18(6) in respect of the ITC availed on the capital goods.

Section 18(6): The Specific Provision for Capital Goods

Section 18(6) provides that where capital goods or plant and machinery, on which ITC has been taken, are supplied, the registered person shall pay GST on the transaction value determined under Section 15, or the ITC originally taken on such capital goods or plant and machinery, reduced by the prescribed percentage points, whichever is higher.

The law therefore does not simply require the taxpayer to return the entire ITC originally claimed. It recognizes the use of the capital asset over a period of time and provides a prescribed reduction mechanism.

How is the ITC Reduced?

The relevant rules prescribe a reduction of ITC by 5 percentage points for every quarter or part thereof from the date of issue of the invoice for such goods.

Broadly:

Reduced ITC = Original ITC × [100% − (5% × number of quarters or part thereof)]

The period is counted from the date of the original invoice relating to the capital goods up to the date of their supply.

Example

Suppose:

• Original cost of machinery = ₹10 lakh
• GST = ₹1.80 lakh
• ITC availed = ₹1.80 lakh
• Machinery sold after 3 years
• Period = 12 quarters

Reduction = 12 × 5% = 60%

Reduced ITC = ₹1.80 lakh × 40% = ₹72,000

The taxpayer would then compare this amount with the GST applicable on the transaction value and pay whichever is higher, subject to the precise statutory calculation applicable to the transaction.

Why Does the Law Use a Quarter-Based Reduction?

The mechanism reflects the principle that capital goods provide utility over a period of time. If the entire ITC had to be reversed even after the asset had been used for several years, the taxpayer could face taxation without recognizing the economic consumption of the asset.

The quarter-based reduction provides a standardized method for reducing the ITC attributable to the remaining period of use. At the same time, the “higher of” mechanism ensures that the Government does not lose GST merely because the prescribed reduced ITC becomes lower than the tax applicable to the actual selling price.

An Important Point: GST on Sale and Section 18(6) Should Not Be Confused

A frequent area of confusion is treating the GST charged on the sale as completely separate from the Section 18(6) calculation without considering the statutory mechanism.

When a capital asset is sold in the course or furtherance of business, the transaction may constitute a supply under GST, and GST is generally required to be charged subject to the applicable provisions.

Section 18(6), however, provides a specific computation for the amount payable where ITC had been availed on the capital goods or plant and machinery.

Businesses should therefore examine whether the asset qualifies as capital goods or plant and machinery, whether ITC was originally availed, the original invoice date, disposal date, transaction value, applicable GST rate, and the amount computed under Section 18(6).

What if the Fixed Asset is Sold at a Loss?

A common misconception is: “If the asset is sold below its book value, there should be no additional GST liability.”

This is not necessarily correct. GST treatment is not determined simply by comparing the sale price with the accounting book value.

For example, a machine may have an original cost of ₹10 lakh, a written-down book value of ₹4 lakh, and a sale price of ₹3 lakh. The accounting loss of ₹1 lakh does not by itself determine the GST liability.

The Section 18(6) mechanism is based on the transaction value and the prescribed reduction in ITC, rather than merely the accounting gain or loss. Depreciation under the books of account and GST ITC reversal should therefore not be mechanically linked.

What if the Asset is Sold After Many Years?

As the period between the original purchase and disposal increases, the ITC amount calculated after the prescribed quarterly reduction progressively decreases.

However, this does not automatically mean that no GST is payable. The taxpayer must still compare the applicable amounts under Section 18(6) and determine the amount payable in accordance with the law.

Therefore, even fully depreciated assets in the books should not be disposed of without reviewing their GST implications.

What About Scrap or Damaged Assets?

Businesses frequently dispose of obsolete machinery, damaged equipment, or other fixed assets as scrap.

The GST treatment requires careful examination of the actual nature of the transaction. If the asset is supplied as scrap, the applicable GST provisions and rate for the relevant supply need to be considered. Where the asset qualifies as capital goods or plant and machinery and ITC was availed, the implications of Section 18(6) should also be examined.

The accounting treatment, such as writing the asset off or recognizing a loss, does not by itself settle the GST position.

Practical Checklist for Businesses

Before selling a fixed asset on which ITC was availed, the finance team should verify:

1. Original ITC — Determine the exact amount of ITC originally availed.
2. Original Invoice Date — Identify the date from which the prescribed quarter-based reduction is to be calculated.
3. Disposal Date — Calculate the number of quarters or part thereof between purchase and disposal.
4. Transaction Value — Determine the value of supply in accordance with the GST valuation provisions.
5. Applicable GST Rate — Identify the GST rate applicable to the particular asset or supply.
6. Section 18(6) Calculation — Calculate the reduced ITC amount as prescribed.
7. Compare the Amounts — Determine the amount payable under the “higher of” mechanism.
8. Documentation — Maintain the original invoice, ITC records, fixed asset register, sale invoice, disposal approval, and calculation supporting the GST treatment.

Why Proper Documentation Matters

Fixed-asset transactions are often reviewed during GST audits because the transaction involves information spread across multiple records: Fixed Asset Register, purchase invoice, ITC records, books of account, GST returns, sale invoice, and e-invoice or e-way bill, where applicable.

A mismatch between these records can lead to questions during departmental scrutiny.

For example, if the fixed asset register shows disposal of machinery but no corresponding outward supply appears in the GST records, the transaction may require explanation.

A documented Section 18(6) working can therefore make the GST treatment significantly easier to substantiate.

Conclusion

The GST treatment of sale of fixed assets on which ITC has been availed requires more than simply charging GST on the sale price or reversing the original ITC.

Section 18(6) of the CGST Act provides a specific mechanism under which the amount payable is determined by comparing the GST applicable on the transaction value with the ITC originally availed after the prescribed reduction.

The key takeaway for businesses is simple: Before disposing of a capital asset, do not look only at its book value or sale price. Review its original ITC, holding period, transaction value, and the Section 18(6) computation.

A proper review at the time of disposal can prevent incorrect ITC reversals, underpayment of GST, interest exposure, and unnecessary disputes during GST audits.
