GST Rule 43: Track Shared Capital Goods Separately

A machine supports taxable and exempt activities; its use changes during the year. The useful result is a working that explains the facts, the calculation or classification, and the evidence behind the conclusion. This guide shows how to prepare that working and where a reviewer should investigate before accepting the result.

Scope and applicable period

Indian GST; apply the law, notification and return version for the transaction’s own period. The worked figures are illustrative, not a declaration of a newly notified rate.

Verification date: 11 October 2026. Figures and rates identified as assumptions are teaching examples; apply the stated conditions and the actual facts to a real assignment.

The key principle

Rule 43 requires an asset-specific approach to capital goods. Identify whether the asset is used exclusively for taxable, exclusively for exempt/non-business or common purposes, then apply the applicable transition and attribution rules. The common capital-credit framework uses a five-year life; this is not the same as book depreciation or income-tax asset life. Changes in use require a fresh working.

Worked example

The example shows one asset in one simplified month. A real register may contain several assets acquired in different months and assets changing category. Track each asset's original invoice, credit amount, initial use and remaining attribution period. Do not restart the useful-life clock merely because the accounting department changes an asset code. Reconcile the total monthly attribution with the GST return and explain disposals or changes in use separately.

A practical sequence

Prepare a capital-goods register linking purchase tax, credit taken, date and actual use. Identify goods used exclusively for taxable, exempt or other relevant purposes and track later changes.

Apply the current Rule 43 calculation to the correct population and period. Reconcile the adjustment to return entries and asset records.

Do not substitute book depreciation or accounting useful life for the prescribed credit mechanism merely because both workings refer to the same asset.

Keep transaction facts and return treatment separate

GST work involves several linked questions: what was supplied, which registration is involved, when liability arises, how it is valued and whether credit is available. A correct accounting entry does not answer all of them. Build the working at invoice level wherever practical, with transaction dates and document references. Reconcile values and tax separately, including amendments and reversals. When a rule or rate changes, use the notified effective date and conditions for the actual transaction; a Council recommendation or a software master update is not, by itself, the legal commencement of the change.

Evidence checklist

Keep the following records linked to the same entity, period and working version. Identify missing items explicitly; a checked box should mean the document was examined and supports the stated conclusion.

• Capital-asset invoices and credit records
• Asset identifier and acquisition month
• Taxable, exempt and non-business use evidence
• Monthly turnover and attribution working
• Change-of-use and disposal history

Common mistakes and how to avoid them

• Using the book depreciation period for GST. Compare the conclusion with the capital-asset invoices and credit records and resolve any conflicting facts.
• Forgetting an asset's earlier credit treatment. Trace the affected item to the taxable, exempt and non-business use evidence before finalising the working.
• Restarting the attribution period on a master-data change. Use the change-of-use and disposal history to make the final position and remaining exceptions clear.

Before you finalise

Recheck the example’s assumptions against the actual assignment, resolve the identified exceptions and make the final figure or conclusion traceable to its source. Preserve the reviewed version and the reason for material changes. For this task, the change-of-use and disposal history should agree with the conclusion presented to the client, reviewer or authority.

Frequently asked question

Can the fixed-asset register alone calculate the reversal? It supplies useful identifiers and dates, but GST use classification and credit history must also be maintained.
