Stopping production does not generally stop depreciation
Ind AS 16 paragraph 55 states that depreciation does not cease merely because an asset becomes idle or is retired from active use, unless it is fully depreciated. A valid usage method can nevertheless produce a zero charge when there is no production. These are different conclusions: a shutdown does not itself justify turning off a straight-line charge or changing the method for a preferred profit result. Read Ind AS 16 paragraphs 50–63.
This guide concerns entities applying Ind AS and was checked on 25 October 2026 against ICAI’s 2025–26 compendium. It addresses book depreciation, not income-tax depreciation or the tax-law 180-day test. Statutory company useful-life requirements and the entity’s documented estimates need their own reconciliation to the financial-reporting framework.
Start from available-for-use status, not first commercial output
Paragraph 55 starts depreciation when PPE is in the location and condition necessary to operate as management intends. First revenue, first full-capacity production and first commercial invoice are not universal start dates. Record commissioning and readiness evidence and distinguish an asset genuinely not yet capable of intended operation from one already ready but temporarily unused.
Once ready, assess idle periods through the established consumption pattern and useful-life estimate. Obsolescence, time and wear can consume benefits even without output. Paragraph 56 expressly considers factors affecting benefits while idle. Repairs and maintenance also do not negate the need for depreciation under paragraph 52.
Zero charges need a supported reason
A units-of-production or other usage method may yield no depreciation where output is zero, if that method continues to reflect consumption appropriately. Paragraphs 60–62 require the method to reflect the expected pattern and be reviewed at least at each financial year-end. Do not switch temporarily from straight line merely because a plant is closed for a weak-sales quarter.
Paragraph 54 provides a separate zero-charge situation where residual value equals or exceeds carrying amount, until residual value subsequently falls below it. A high market valuation is not necessarily residual value, and paragraph 52 recognises depreciation despite fair value exceeding carrying amount where the residual condition is not met. Support the estimate rather than citing an unrelated market quotation.
Held for sale and derecognition are separate events
Depreciation ceases at the earlier of classification as held for sale, including within a qualifying disposal group under Ind AS 105, and derecognition. Management’s intention to sell an idle machine is not itself proof that the Ind AS 105 classification criteria are met. Preserve the classification analysis and date; until the proper trigger occurs, idleness alone does not stop the charge.
A fully depreciated asset still in service needs an asset-register and disclosure review, not depreciation below its properly established residual value by default. If estimates were materially wrong, determine the relevant estimate-change or error framework from the facts rather than rewriting earlier years solely because the asset outlived an expectation.
Annual estimate review and impairment remain necessary
Paragraph 51 requires residual value and useful life to be reviewed at least at each financial year-end, with changes in expectations accounted for as estimate changes under Ind AS 8. Paragraph 61 similarly addresses changed consumption patterns and methods. A supported new remaining life changes future depreciation; it is not automatically a retrospective catch-up to an imagined original life.
Paragraph 63 refers PPE impairment to Ind AS 36. Continuing depreciation does not establish recoverability, while a zero usage charge does not prove the asset has no impairment. Maintain the readiness record, idle-period reasons, method, residual value, remaining life, held-for-sale analysis and separate impairment conclusion. The examples stipulate simple straight-line or output models, ignore tax effects and use equal monthly fractions where explicitly stated.
Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Straight line during a full idle year
Assume cost ₹12,00,000, residual value ₹2,00,000 and ten-year useful life, with the asset ready for use throughout the year and no changed estimates or other cessation event. Annual depreciation is (₹12,00,000 − ₹2,00,000) ÷ 10 = ₹1,00,000 even if it is idle for the entire year.
Illustrative example 2: Idle quarter is not a holiday from the charge
Under the same stipulated straight-line model, the machine operates for nine months and is idle for three. Annual charge remains ₹1,00,000. Restricting it to nine-twelfths would give ₹75,000 and understate the model charge by ₹25,000.
Illustrative example 3: Valid output method, zero output
Assume a properly supported units-of-production method, remaining depreciable amount ₹6,00,000 and remaining expected output 30,000 units. The rate is ₹20 per unit. With zero production, the model charge is ₹0; a later 5,000-unit period would contribute ₹1,00,000, subject to the applicable remaining estimates.
Illustrative example 4: Residual value reaches carrying amount
Assume carrying amount ₹4,00,000 and a properly supported revised residual value of ₹4,20,000. The residual exceeds carrying amount by ₹20,000. Under paragraph 54, charge is ₹0 while that condition persists; this is not a rule to recognise a ₹20,000 revaluation gain.
Illustrative example 5: Supported held-for-sale date
Assume an annual straight-line charge of ₹1,20,000 and a valid Ind AS 105 classification effective 1 October in a year beginning 1 April. Under the stipulated equal-month model, six months’ depreciation before classification is ₹60,000. Stopping from 1 July merely because the asset became idle then would produce ₹30,000 and miss ₹30,000 before the actual cessation trigger.
Illustrative example 6: Prospective remaining-life change
At the start of the model year, carrying amount is ₹9,00,000 and residual ₹1,00,000. A supported estimate revises remaining useful life from four years to eight. Prospective annual straight-line charge is ₹8,00,000 ÷ 8 = ₹1,00,000 rather than ₹2,00,000 under the old remaining-life estimate. No retrospective adjustment is inferred from these stipulated estimate-change facts.

Sixteen practitioner FAQs
1. Does a factory shutdown automatically stop depreciation?
No. Idleness alone does not stop the charge under paragraph 55.
2. Does first revenue control the start date?
Not universally. The available-for-use condition is the relevant starting point.
3. Can an unused ready machine require depreciation?
Yes, subject to its method and the applicable exceptions.
4. Does maintenance remove the need to depreciate?
No. Paragraph 52 addresses that distinction.
5. Can straight-line depreciation be reduced solely for idle months?
Not merely because no production occurred; apply the supported method and estimates.
6. Can a valid usage method give zero depreciation?
Yes, the standard recognises that possibility when there is no production.
7. Can management switch methods just to avoid a shutdown charge?
The method must reflect expected consumption and changes need support under the estimate framework.
8. Does high fair value automatically mean no depreciation?
No. Fair value and residual value are different concepts in this analysis.
9. What if residual value equals carrying amount?
Paragraph 54 provides a zero charge while its condition holds.
10. Can the asset be depreciated below residual automatically?
No. Apply the depreciable-amount and estimate requirements.
11. Does an intention to sell equal held-for-sale classification?
No. Establish the actual Ind AS 105 criteria and date.
12. Can a fully depreciated asset remain in use?
Yes. Review the register, estimates and relevant disclosures rather than assuming use is impossible.
13. How often are useful life and residual reviewed?
At least at each financial year-end under paragraph 51.
14. Is a supported remaining-life change automatically retrospective?
No. An estimate change is treated under the Ind AS 8 estimate framework.
15. Does a zero usage charge eliminate impairment risk?
No. Impairment is a separate Ind AS 36 assessment.
16. Does this apply the income-tax 180-day rule?
No. This is an Ind AS book-depreciation analysis.
Conclusion
Ind AS 16 generally continues depreciation when PPE becomes idle or leaves active use. Separate straight-line depreciation from a valid usage-based zero-production charge, full depreciation, residual-value effects and held-for-sale classification; review estimates and impairment independently.
