If you have ever stared at a brand-new machine sitting in a warehouse, still wrapped in plastic, and wondered whether you should already be depreciating it, you are not alone. This is one of the most common doubts finance professionals raise during audits and statutory filings. The short answer, and the one IAS 16 is very clear about, is that IAS 16 depreciation begins when asset is available for use, not when it is actually put into service.
That single sentence trips up a lot of accountants because “available for use” and “actually being used” sound almost identical in everyday language, but IFRS treats them very differently. Getting this timing wrong can distort your profit figures, understate your asset base, and even raise red flags with auditors who are specifically trained to check this cut-off point.
In this article, we will unpack exactly what “available for use” means under IAS 16, walk through practical examples from manufacturing, real estate, and IT assets, and explain why so many preparers get the starting point wrong. Once you understand that IAS 16 depreciation begins when asset is available for use, you’ll stop second-guessing your fixed asset register every time a new machine arrives on site. This concept also comes up repeatedly if you’re building a career in global financial reporting, which is exactly why professionals enrolling in an International Accounting Standards Course spend an entire session just on recognition and measurement timing. It is a small phrase with a big impact on the financial statements, and once it clicks that IAS 16 depreciation begins when asset is available for use, every related judgment call gets easier.
What Does “Available for Use” Actually Mean?
IAS 16 defines the starting point for depreciation as the date the asset is in the location and condition necessary for it to operate in the manner intended by management. That is a mouthful, but it boils down to one practical test: can the asset do its job right now, even if nobody has pressed the start button yet? If the answer is yes, IAS 16 depreciation begins when asset is available for use, regardless of whether production has actually commenced.
The Difference Between “Available” and “In Use”
Think about a newly installed packaging line. Once your engineers have completed installation, run the commissioning tests, and confirmed the machine works exactly as intended, the asset is available for use, even if the factory hasn’t received its first production order yet. Many preparers mistakenly wait until the first unit rolls off the line before starting depreciation, but that is not what the standard requires. The same logic, incidentally, shows up when professionals are comparing lease accounting cut-off dates while studying IFRS 16 Leases, where the “commencement date” concept creates a similar but distinct timing question.
Why the Timing Matters So Much
Getting the start date wrong has a direct impact on your financial statements. Delay depreciation unnecessarily and you overstate profits and net asset values for that period. Start it too early, before the asset is genuinely ready, and you understate performance and could mislead stakeholders about operational readiness. Auditors routinely test this cut-off during year-end reviews because it is an easy area to manipulate, intentionally or otherwise. It is worth repeating the core principle here because it is so often forgotten under deadline pressure: IAS 16 depreciation begins when asset is available for use, and that single fact should anchor every fixed-asset schedule you prepare.
Preparers sometimes argue that depreciation should wait until an asset starts “earning” revenue, confusing an accounting trigger with a commercial milestone. The standard does not ask whether the asset is earning anything; it only asks whether the asset could function as intended if called upon. That distinction, small as it sounds, is the reason year-end adjustments on fixed assets are among the most frequent audit findings in manufacturing and infrastructure companies alike.
This is also where IAS 16 connects with other standards you’ll encounter in practice. For instance, revenue teams often ask finance why a new production asset isn’t yet depreciating even though related contracts have already been signed, a question that usually gets resolved once you understand how recognition timing is treated separately under IFRS 15 Revenue Recognition, since contract signing and asset readiness are two completely independent triggers.
Common Scenarios Where Preparers Get It Wrong
Three situations trip people up again and again. Waiting for formal “commercial production” before starting depreciation, when the asset was technically ready weeks earlier. Assuming installation completion automatically means “available for use,” without accounting for mandatory commissioning or safety trials. Treating a phased rollout, say five machines in a line, as a single asset, when each machine may reach “available for use” status on a different date.
In every one of these cases, the underlying principle is unchanged: IAS 16 depreciation begins when asset is available for use, and management’s intention to delay commercial operations for business reasons does not change the accounting answer.
How to Apply the “Available for Use” Test in Practice
A good working checklist includes physical installation, completion of commissioning and test runs, all required regulatory or safety certifications, and confirmation that the asset can function as management intends, even in a limited capacity. Once all four boxes are ticked, the clock starts. This is precisely the kind of applied, example-driven understanding that a structured financial statements course builds through case studies rather than textbook definitions alone.
Trial Production and Testing Costs
One nuance worth flagging: costs incurred during testing, net of any proceeds from selling items produced while testing, like trial-run units, are included in the cost of the asset, not expensed, and not treated as the trigger for depreciation. The depreciation start date is still governed by availability, not by whether testing output was sold commercially. Preparers who confuse these two things often end up capitalizing testing costs correctly but still get the start date wrong, because they wait for testing revenue to appear before running their first depreciation entry. Keep the two questions separate, and remember that IAS 16 depreciation begins when asset is available for use well before any test-run proceeds are even recorded.
A Practical Example
Suppose a company installs a new industrial oven in March. Installation finishes on the 10th, commissioning and safety tests wrap up on the 18th, and the final safety certificate arrives on the 20th. Commercial production, however, doesn’t start until April 5th because of a delayed raw material shipment. Under IAS 16, depreciation should start on March 20th, the date the oven was ready and able to operate as intended, not April 5th. This is a textbook case of IAS 16 depreciation begins when asset is available for use rather than when revenue-generating activity begins.
Key Takeaways for Finance Professionals
The availability test, not the usage test, governs the depreciation start date. Location and condition “necessary for operation as intended” is the legal threshold. Commissioning, testing, and certification matter; commercial production dates do not. Each identifiable component of a larger installation may have its own “available for use” date.
Keeping these points in mind will help you avoid the single most common error examiners and auditors flag: delaying the depreciation start date simply because business operations haven’t technically begun, when in fact IAS 16 depreciation begins when asset is available for use the moment the asset itself is ready.

If this topic felt more complicated than it should, that’s exactly the gap caswatigupta’s training programs are built to close. Rather than memorizing definitions, you work through real fact patterns, installation dates, commissioning reports, and certification timelines, until recognizing exactly when IAS 16 depreciation begins when asset is available for use becomes second nature rather than a guessing game. caswatigupta’s courses are designed by practitioners who have actually closed these books and defended these judgment calls to auditors, so what you learn maps directly onto the questions you’ll face at work or in your IFRS and Ind AS exams. Whether you’re a working professional brushing up before appraisal season or a student preparing for certification, caswatigupta keeps the explanations practical, example-heavy, and genuinely usable from day one.
Frequently Asked Questions
1. Does IAS 16 depreciation begin on the date of purchase or the date of installation?
Neither, automatically. IAS 16 depreciation begins when asset is available for use, meaning installation, commissioning, and any required certification must all be complete first.
2. What if the asset is ready but management chooses to delay using it for business reasons?
It doesn’t matter. Once the asset is in the location and condition necessary to operate as intended, depreciation starts, regardless of management’s commercial decision to wait.
3. Can depreciation start before commercial production begins?
Yes, and in most real-world cases it should. IAS 16 depreciation begins when asset is available for use, not when the first commercial unit is produced or sold.
4. How does this rule differ under Ind AS?
Ind AS 16 mirrors IAS 16 almost word-for-word on this point, so the “available for use” trigger applies identically in Indian financial statements.
5. What costs are included before depreciation starts?
Installation, delivery, site preparation, and testing costs, net of proceeds from test-run output, are capitalized into the asset’s cost, but none of these costs change the depreciation start date, which remains tied to availability, not expenditure.
