Different Depreciation Rates under Companies & Income Tax Act
Different Depreciation Rates under Companies & Income Tax Act
Depreciation is a key concept in finance and accounting. It helps us manage how the value of assets changes over time. Think of it as a way to spread out the cost of an asset over its useful life. We use depreciation to account for things like wear and tear, obsolescence, or new technology. In this guide, we’ll break down depreciation, its purpose, types of assets, how to calculate it, and the differences between accounting and tax rules. Whether you’re a business owner, finance pro, or just curious about finance, this article will help you understand how depreciation impacts a company’s financial performance and reporting.
What is Depreciation?
Depreciation is a measure of the reduction in the value of a depreciable asset. This decline in value can occur due to various factors such as usage, the passage of time, or becoming obsolete because of technological or market changes.
Depreciation is allocated fairly and systematically to account for this reduction in value. This allocation is done over the expected useful life of the asset. Each accounting period sees a portion of the depreciable amount being charged as depreciation.
Since almost all assets lose value over time, we treat depreciation as an expense in financial accounting. This is advantageous to the company that owns the depreciable assets, as it allows for a more accurate representation of the asset’s value over time.
Recording Depreciation in Financial Statements
The depreciation charged on depreciable assets is recorded as an expense in the Profit & Loss Account. This accounting practice helps recognise the reduction in asset value over time.
The depreciation expense listed in the Profit & Loss Account compensates the company for the value lost on its depreciable assets. It helps maintain transparency and accuracy in financial reporting.
Types of Depreciable Assets
Depreciable assets are those used for business purposes that can be depreciated over time. These assets encompass both tangible and intangible categories.
- Tangible assets include buildings, machinery, vehicles, furniture, fixtures, computers, and equipment.
- Intangible assets subject to depreciation include patents, copyrights, and computer software.
Depreciation is a vital tool in managing and accounting for the value of these assets over their useful lifespan.
The Purpose of Depreciation
Depreciation can be a complex concept in accounting, primarily because it does not involve actual cash flow. The primary purpose of depreciation is to allocate a portion of an asset’s cost to the Profit & Loss Account. This allocation is based on the “matching principle,” where revenues and expenses are recorded in the Profit & Loss Account within the same reporting period. This principle provides a more accurate view of a company’s performance during a specific reporting period.
Determining When to Stop Depreciating
Depreciation ceases when one of two conditions is met:
- The business disposes of the asset.
- The asset reaches the end of its useful life.
The Importance of Depreciation
Without the practice of charging depreciation, businesses would be required to expense the entire cost of their assets immediately upon acquisition. This would result in substantial losses in the months of purchase, followed by unusually high profitability in the periods when corresponding revenue is recognized without any matching expenses. Consequently, a company that doesn’t implement depreciation would experience highly variable financial results. Depreciation, therefore, provides a more balanced and accurate representation of a company’s financial performance over time.
Two Methods of Depreciation Calculation
Depreciation calculation is an annual practice that follows specific methods outlined in statutory regulations. The Companies Act guides two distinct methods for calculating depreciation:
Straight Line Method (SLM):
The straight-line method allocates an equal portion of an asset’s cost as depreciation each year. This method offers a straightforward approach to depreciation calculation.
Written Down Value Method (WDV):
As specified in the Companies Act and the Income Tax Act of 1961, the Written Down Value Method calculates depreciation based on the block of assets criteria. This method typically results in a declining balance of depreciation over time.

Depreciation under the Income Tax Act, 1961
Under the Income Tax Act, 1961, depreciation is calculated following the Block of Assets criteria. The Written Down Value (WDV) Method is typically followed for tax purposes.
Rate of Depreciation under the Companies Act 2013
The Indian Companies Act, 2013, outlines the useful life of various classes of assets in Schedule II. This schedule serves as the basis for determining the rate of depreciation under the Straight Line Method (SLM), Written Down Value Method (WDV), or Unit of Production (UOP) method.
Impact of Depreciation Method
The choice of depreciation method directly impacts a company’s profit and the carrying value of its assets. It influences how the expense is recognized over time and the presentation of asset values in the financial statements. Careful consideration of the chosen method is essential to represent a company’s financial performance and asset values accurately.
Differences in Depreciation between the Income Tax Act and Companies Act
Depreciation serves two distinct purposes in accounting and taxation, leading to variations in how it is calculated under the Income Tax Act and the Companies Act.
Accounting Purpose
Depreciation in accounting involves two aspects: reducing the value of assets and allocating asset costs over their useful life. Under the Companies Act, 2013, depreciation is calculated based on the useful life of assets rather than predetermined rates. This approach aims to represent the value decline of assets over time accurately. The Companies Act provides a reference chart of useful lives.
Taxation Purpose
Depreciation in taxation aims to reduce a company’s net taxable income and, consequently, the tax payable. Under the Income Tax Act, 1961, depreciation on assets is treated as an expense when calculating income under the “Income from Business and Profession” category. Depreciation rates are specified in the Income Tax Act based on the block of assets. This method is used to determine tax liability.
Differences in Methods Lead to Varied Depreciation Amounts
Because of these differences in depreciation methods between taxation and accounting purposes, the depreciation amounts calculated under the Income Tax Act and the Companies Act may not align. This results in a timing difference that must be quantified in the company’s financial statements. This quantification takes the form of deferred tax liability or deferred tax asset.
Deferred Tax Considerations
The timing difference in depreciation between the two acts leads to deferred tax considerations. A deferred tax liability or asset is recognized in the financial statements to account for the temporary variance in depreciation amounts. This recognition ensures that the company’s financial reporting accurately reflects its tax obligations and financial position.

Methods of Calculating Depreciation
Different methods are employed to calculate depreciation, which can vary depending on the type of asset and the industry. These methods also differ when it comes to accounting and taxation purposes. The two most commonly used depreciation methods are the Straight-Line and Written Down Value Method.
Depreciation calculations under the Income Tax Act and the Companies Act mainly differ in the method used for depreciation calculation.
Depreciation Methods as per Companies Act, 1956 (Based on Specified Rates):
- Straight Line Method
- Written Down Value Method
Depreciation Methods as per Companies Act, 2013 (Based on Useful Life of Assets):
- Straight Line Method
- Written Down Value Method
- Unit of Production Method
Depreciation Methods as per Income Tax Act, 1961 (Based on Specified Rates):
- Written Down Value Method (Block-wise)
- Straight Line Method (specifically for Power Generating Units)
Formula for Calculating Depreciation by Straight-Line Method
For the Straight-Line Method, you can calculate the rate of depreciation and the actual depreciation using the following formulas:
- Straight-Line Method Rate of Depreciation = [(Original Cost – Residual Value) / Useful Life] x 100
- Depreciation = Original Cost x Rate of Depreciation under Straight-Line Method (as calculated in formula ‘a’)
