Companies Act Depreciation Rules Explained for Fixed Asset Users.

Introduction to Depreciation in Corporate Accounting

Depreciation is one of the most important concepts in financial accounting for companies operating under Indian law. Every business that owns fixed assets such as machinery, buildings, vehicles, furniture, or computers must account for the reduction in value of these assets over time. This reduction is not random—it is systematic and follows legal and accounting standards.

Under Indian corporate law, the concept of depreciation is governed mainly by the Companies Act, 2013, specifically Schedule II. This schedule defines how companies should estimate the useful life of assets and calculate depreciation accordingly.

In simple terms, depreciation ensures that companies do not show inflated profits by ignoring the gradual wear and tear of assets. Instead, the cost of the asset is distributed over its useful life.

In modern accounting practice, depreciation as per companies act is not just a technical requirement—it is a reflection of financial truth. It ensures that financial statements present a fair and realistic picture of the company’s financial position.

Meaning and Concept of Depreciation in Simple Terms

Depreciation refers to the gradual reduction in the value of a tangible fixed asset due to usage, aging, technological changes, or wear and tear. When a company purchases an asset, it does not remain useful forever. Over time, its efficiency declines.

For example, a machine purchased for production will slowly lose its efficiency after continuous use. Similarly, a company vehicle will lose value as it is driven over the years.

Instead of recording the full cost of the asset as an expense in one year, accounting rules spread this cost over several years. This ensures that profit is calculated fairly.

The concept of depreciation as per companies act helps businesses match expenses with the revenue generated from using those assets.

Why Depreciation is Important for Companies

Depreciation plays a crucial role in financial reporting, taxation planning, and business decision-making. Without depreciation, financial statements would show unrealistic profits and asset values.

One of the most important purposes of depreciation is to match costs with revenue. If an asset helps generate income over ten years, its cost should be distributed over those ten years rather than charged in one year.

Another important reason is asset valuation. Depreciation ensures that the balance sheet reflects the actual reduced value of assets instead of outdated original costs.

Depreciation also helps in replacement planning. Companies can estimate when an asset will need replacement and plan finances accordingly.

Ultimately, depreciation as per companies act ensures transparency, compliance, and accuracy in financial reporting.

Legal Framework of Depreciation Under Companies Act 2013

The Companies Act, 2013 introduced Schedule II, which replaced earlier fixed depreciation rates with a more flexible system based on useful life.

Schedule II provides:

• Useful life of different categories of assets
• General guidelines for residual value
• Requirement for component-wise accounting
• Flexibility for companies with justification

Earlier, companies followed fixed rates under the Companies Act 1956. However, the new system is more realistic because different companies may use assets differently.

For example, a machine used in a factory running 24 hours a day will wear out faster than one used for 8 hours a day.

Therefore, depreciation as per companies act now focuses on economic reality rather than fixed percentages.

Understanding Useful Life of Assets

Useful life refers to the period over which an asset is expected to be used by a company. It is not necessarily the total physical life of the asset but the period during which it provides economic benefit.

For example, a computer may physically last 8 years, but due to technological changes, its useful life may be only 3 to 6 years.

Schedule II provides indicative useful lives for different assets, but companies can adjust them based on justification.

This flexibility is an important feature of depreciation as per companies act.

Methods of Depreciation Used in Companies

Companies can use different methods to calculate depreciation, but the two most common methods are Straight Line Method (SLM) and Written Down Value Method (WDV).

Straight Line Method (SLM)

Under SLM, depreciation is charged equally every year over the useful life of the asset.

This method is simple and widely used for assets that provide equal benefit over time.

The formula is:

Depreciation=Cost of Asset−Residual ValueUseful Life\text{Depreciation} = \frac{\text{Cost of Asset} – \text{Residual Value}}{\text{Useful Life}}Depreciation=Useful LifeCost of Asset−Residual Value​

This method is often used for furniture, buildings, and simple machinery.

Written Down Value Method (WDV)

Under WDV method, depreciation is charged at a fixed percentage on the reducing balance of the asset.

In early years, depreciation is higher, and in later years, it decreases.

This method is useful for assets that lose value quickly in the beginning, such as vehicles or computers.

Both methods are acceptable under depreciation as per companies act, provided they are consistently applied.

Example of Depreciation Calculation

Let us assume a company purchases machinery:

• Cost = ₹10,00,000
• Residual Value = ₹50,000
• Useful Life = 10 years

Step 1: Calculate depreciable amount

₹10,00,000 − ₹50,000 = ₹9,50,000

Step 2: Annual depreciation using SLM

9,50,00010=95,000\frac{9,50,000}{10} = 95,000109,50,000​=95,000

So, the company will charge ₹95,000 per year as depreciation.

This ensures proper matching of expense and revenue under depreciation as per companies act.

Residual Value and Its Importance

Residual value is the estimated amount a company expects to recover at the end of an asset’s useful life.

It can come from:

• Sale of old machinery
• Scrap value
• Secondary market resale

Under Schedule II, residual value is usually limited to 5% of the asset cost unless justified.

This ensures realistic valuation in financial statements.

Component Accounting Concept

Component accounting is an advanced concept introduced in Schedule II.

It means that if an asset has significant parts with different useful lives, each part should be depreciated separately.

For example:

• A building has roof, structure, and electrical systems
• An aircraft has engines, body, and interior components

Each part depreciates differently.

This improves accuracy in depreciation as per companies act.

When Depreciation Starts and Ends

Depreciation begins when the asset is ready for use, not necessarily when it is purchased.

For example:

• If machinery is installed in March but starts production in April, depreciation may start from April.
• If an asset is not in use but ready, depreciation may still apply depending on policy.

Depreciation stops when:

• Asset is fully depreciated
• Asset is sold or disposed

This timing is important for accurate accounting.

Difference Between Accounting and Tax Depreciation

Accounting depreciation (Companies Act) and tax depreciation (Income Tax Act) are not the same.

Accounting depreciation is based on useful life, while tax depreciation is based on fixed block rates.

This difference often creates deferred tax adjustments.

Disclosure Requirements in Financial Statements

Companies must disclose depreciation policies clearly in financial statements.

Disclosures include:

• Method of depreciation
• Useful life of assets
• Gross block and net block
• Accumulated depreciation
• Changes in estimates

These disclosures ensure transparency and compliance.

Common Mistakes in Depreciation Accounting

Many companies make errors while calculating depreciation:

• Using wrong asset classification
• Not updating useful life estimates
• Ignoring asset disposal entries
• Mixing tax and accounting depreciation
• Not maintaining asset register

Avoiding these mistakes ensures correct application of depreciation as per companies act.

Impact of Depreciation on Financial Statements

Depreciation affects both the profit and balance sheet.

In the profit and loss statement, it reduces profit as it is treated as an expense.

In the balance sheet, it reduces asset value through accumulated depreciation.

This dual impact makes depreciation a powerful accounting adjustment.

Practical Importance in Business Decisions

Depreciation is not just accounting—it influences real business decisions:

• Asset replacement planning
• Budget forecasting
• Investment decisions
• Loan eligibility
• Tax planning

Businesses that manage depreciation effectively often make better financial decisions.
