Depreciation Rates and Rules for the Financial Year 2025-26 under the Income Tax Act

Depreciation Under Indian Income Tax Act 2025. The purpose of this report is to provide a definitive guide to the depreciation rates and foundational principles applicable for the financial year 2025-26 under the Indian Income Tax Act. A key finding of this analysis is that, based on a review of legislative documents, including the Indian Finance Bill, 2025, there have been no changes proposed to the prescribed depreciation rates or the core rules governing their calculation. The rates and regulations established under the Income Tax Act, 1961, and its corresponding rules (Appendix I), remain in effect. This stability offers a clear and predictable framework for businesses and assessees in India for the upcoming assessment year. This report serves as a consolidated reference, reconciling information from various sources to provide an accurate and authoritative guide for financial and tax planning. It covers the legal basis of depreciation, a detailed rate chart for all major asset classes, an in-depth analysis of key concepts, and actionable recommendations for ensuring compliance and optimizing tax positions.

Part I: Foundational Principles of Depreciation in India

1.1. The Concept and Purpose of Depreciation

Depreciation is a fundamental financial concept that accounts for the reduction in the value of an asset over time. This decrease in value can be attributed to several factors, including wear and tear from use, obsolescence due to technological advancements, or simply the passage of time. Under the Indian Income Tax Act, depreciation is not merely an accounting entry; it is a mandatory deduction that a business can claim to reduce its taxable income. The legal rationale for this deduction is to allow businesses to spread the cost of a tangible or intangible asset over its useful life, thereby providing a fair mechanism for cost recovery and reflecting the true economic reality of an asset’s declining value. It is important to note that certain assets are explicitly excluded from depreciation claims, most notably the cost of land and goodwill.  

1.2. The Governing Legal Framework: Section 32 of the Income Tax Act

The allowance for depreciation in India is governed by Section 32 of the Income Tax Act, 1961. A critical aspect of this framework is the clear distinction between depreciation for income tax purposes and depreciation as calculated under other statutes, such as the Companies Act. The Income Tax Act has its own prescribed rates and methods, which must be followed for tax reporting and compliance, irrespective of the depreciation method or rates used for a company’s financial books. This separation of rules is a deliberate feature of the regulatory landscape, ensuring that tax calculations adhere to a standardized, statutory approach.  

1.3. Methods of Depreciation and the “Block of Assets” Principle

The Income Tax Act primarily allows for two methods of calculating depreciation, each with a specific application.

The Written Down Value (WDV) Method The WDV method is the most commonly used and the default method for income tax purposes across most industries in India. Under this method, depreciation is calculated on the asset’s remaining value, or its “written down value,” each year. This approach results in a higher depreciation deduction in the initial years of an asset’s life and progressively lower deductions in subsequent years. This front-loading of deductions can be strategically advantageous for businesses seeking to reduce their taxable income during periods of high growth or investment. The formula for the annual depreciation amount is straightforward:  

Annual Depreciation=Opening WDV×Depreciation Rate  

The Straight-Line Method (SLM) The SLM is an exception to the general rule and is available only to specific undertakings, particularly those engaged in power generation or generation and distribution. This method calculates depreciation as a fixed percentage of the original cost of the asset. As a result, the depreciation amount remains constant throughout the asset’s useful life. This method is often preferred for its simplicity and the predictability it offers in long-term financial planning.  

The “Block of Assets” Principle A foundational principle of the Indian tax system, which sets it apart from traditional accounting, is the concept of a “block of assets. Under this rule, depreciation is not calculated on individual assets but rather on a group of assets that fall under the same class and are subject to the same depreciation rate. When an asset is acquired, its cost is added to the relevant block. Conversely, when an asset is sold, its sale proceeds are deducted from the block’s value. This means that for tax purposes, individual assets lose their specific identity once they are added to a block. The system calculates the aggregate depreciation for the entire block, simplifying the process and ensuring continuity.  

1.4. Conditions for a Valid Depreciation Claim

To claim depreciation under the Income Tax Act, an assessee must meet several essential conditions:

• Ownership: The assessee must own the asset, either wholly or partly. This is a crucial requirement, as only the legal owner has the right to claim the deduction.  
• Business Use: The asset must be used for the purpose of a business or profession. If an asset is used for both business and non-business purposes, the depreciation is allowed only on a proportionate basis.  
• Mandatory Claim: Since Assessment Year 2002-03, the claim for depreciation is considered “allowed or deemed allowed,” regardless of whether the assessee has actually claimed it in their books. This means that the WDV of the asset block will be mandatorily reduced by the eligible depreciation amount, preventing assessees from strategically carrying forward depreciation to future years.  
• Exclusion for Presumptive Taxation: If a business opts for a presumptive income scheme, it cannot claim depreciation separately, as the deduction is considered to have been already factored into the presumptive income calculation.  

Part II: Detailed Depreciation Rate Chart for FY 2025-26

The following table presents a consolidated and reconciled chart of the depreciation rates applicable for the financial year 2025-26, based on the provisions of the Income Tax Act, 1961, and its rules.

Asset Class	Asset Type	Depreciation Rate (WDV Method)
A. Tangible Assets
Buildings	Residential buildings (excluding hotels & boarding houses)	5%
	Non-residential buildings (offices, factories, etc.) and hotels/boarding houses	10%
	Purely temporary constructions (e.g., wooden structures)	40%
Furniture and Fittings	Any furniture or fittings, including electrical fittings	10%
Plant and Machinery	General machinery (not otherwise specified)	15%
	Motor cars, motorcycles, scooters, and bikes (non-commercial use)	15%
	Motor buses, lorries, and taxis (used for hire)	30%
	Special vehicles acquired between Aug 23, 2019 & Apr 1, 2020	30%-45%
	Computers and computer software	40%
	Aeroplanes and aero-engines	40%
	Pollution control equipment (air, water, solid waste)	40%
	Renewable energy devices (solar, wind energy)	40%
	Books (annual publications, lending libraries)	40% (since 2017)
Ships	Ocean-going ships, vessels, etc.	20%
B. Intangible Assets
Intangible Assets	Know-how, patents, copyrights, trademarks, licenses, franchises, or other similar business rights	25%

A key aspect of the depreciation rates is the standardization of many high rates to a maximum of 40% effective from April 1, 2017. This is a crucial point of clarification, as some older documents may still reference historical rates of 60%, 80%, or even 100% for certain assets. These higher rates for assets like pollution control equipment, renewable energy devices, and computers reflect a deliberate policy decision. Assets such as computers and software have a rapid obsolescence cycle, a fact acknowledged by their higher depreciation rate, which allows businesses to write off their costs more quickly. Similarly, the higher rates for pollution control and renewable energy devices act as a powerful tax incentive to encourage businesses to invest in environmentally beneficial technologies.  

Part III: In-depth Analysis and Strategic Considerations

3.1. Practical Application of the “Block of Assets” Rule

Understanding the practical application of the WDV and “block of assets” rules is essential for accurate tax planning. The calculation is performed on the aggregate value of the block, not on individual assets. When an asset is acquired, its actual cost is added to the block’s opening WDV. Depreciation is then calculated on this new, higher value. If an asset is sold, the proceeds from the sale are deducted from the block’s value.

Consider a simple example based on the WDV method :  

Example 1: Depreciation of a Machinery Block (15% Rate)

A business acquires machinery for 1,00,000.

• Year 1:
  • Opening WDV = 1,00,000
  • Depreciation = 1,00,000×15%=15,000
  • Closing WDV = 1,00,000−15,000=85,000
• Year 2:
  • Opening WDV = 85,000
  • Depreciation = 85,000×15%=12,750
  • Closing WDV = 85,000−12,750=72,250
• Year 3:
  • Opening WDV = 72,250
  • Depreciation = 72,250×15%=10,838
  • Closing WDV = 72,250−10,838=61,412

This illustration demonstrates how the depreciation amount decreases each year as it is calculated on the reducing WDV. The same principle applies to an entire block of assets. If an asset within a block is sold, the remaining value of the block is adjusted by the sale proceeds. Any loss incurred from the sale of a depreciated asset can be adjusted against other business income.  

3.2. Special Scenarios and Nuances

Depreciation on Leased vs. Owned Assets The right to claim depreciation is inextricably linked to ownership. In the case of an operating lease or a hire agreement, the lessee (the user of the asset) cannot claim depreciation, as legal ownership remains with the lessor. The lessor, as the owner, is entitled to the deduction. An exception to this rule may exist in a finance lease, where the lessee can sometimes claim depreciation if the asset is capitalized in their books of accounts.  

Depreciation on Property: The Treatment of Land A common point of confusion arises with the depreciation of buildings and the land on which they are built. The Income Tax Act clarifies that while the building itself is a depreciable asset, the cost of the underlying land is not eligible for depreciation. This is because land is considered a non-depreciable asset, as its value does not reduce due to wear and tear or usage.  

Depreciation for Tax vs. for Insurance It is crucial to differentiate between depreciation for income tax purposes and the concept of depreciation used for calculating the Insured Declared Value (IDV) of a vehicle for insurance. Tax depreciation is a statutory deduction to reduce taxable income, governed by the fixed rates of the Income Tax Act and the WDV method. In contrast, depreciation for insurance is a valuation method used by the insurance provider to determine the vehicle’s current market value at the time of policy renewal. The rates for IDV are typically based on the vehicle’s age, with values decreasing significantly in the first few years. A professional must not conflate these two distinct concepts, as they serve different purposes and are governed by separate rules.  

3.3. The Finance Bill, 2025: Debunking Misconceptions

The user’s query about “2025” and the provided research material highlight a potential point of confusion stemming from global legislative updates. A careful analysis of the provided information confirms that while legislative activities are underway in various jurisdictions, there have been no changes to the Indian depreciation rates.

The Indian Finance Bill, 2025, details proposed amendments related to direct taxes, including tax rates, but it contains no provisions for altering depreciation rates or rules. The existing framework of Section 32 of the Income Tax Act, 1961, remains the sole authority on the matter.  

In stark contrast, a review of legislative proposals in other regions, such as the United States, reveals a different tax landscape. A bill titled the “One Big Beautiful Bill Act of 2025″ in the U.S. proposes a significant change by restoring 100% bonus depreciation for “qualified property. This means that businesses could fully deduct the cost of certain capital investments in the year of acquisition, a move designed to stimulate investment and economic growth. This global context helps explain why an individual searching for “depreciation rate chart 2025″ might anticipate a major legislative overhaul. However, it is essential to clarify that such changes are jurisdiction-specific and do not apply to the Indian tax regime. While some clauses in the Indian bill may address the calculation of the written down value or other tax matters , these are not amendments to the depreciation rates themselves.  

Part IV: Summary and Recommendations

Key Takeaways

• Stability of Rates: The depreciation rates prescribed under the Indian Income Tax Act for the financial year 2025-26 are stable, with no changes announced in the Indian Finance Bill, 2025.  
• WDV is the Rule: The Written Down Value (WDV) method remains the default and mandatory method for calculating depreciation for tax purposes, applied to a “block of assets” rather than on an individual asset basis.  
• 40% Maximum: Many assets that were historically eligible for higher rates of 60%, 80%, or 100% are now subject to a maximum depreciation rate of 40%. This applies to computers, pollution control equipment, renewable energy devices, and certain books.  
• Clarity on Concepts: The concept of depreciation for income tax is a distinct and separate concept from that used for financial accounting or for determining a vehicle’s Insured Declared Value (IDV) for insurance purposes.  

Recommendations for Assessees

To ensure compliance and optimize tax benefits for the financial year 2025-26, assessees should take the following steps:

• Maintain Meticulous Documentation: It is imperative to maintain proper records, including proof of asset ownership (e.g., purchase invoices), date of acquisition, and documentation of business use. Accurate records are essential to substantiate any depreciation claims during a tax assessment.  
• Correct Asset Classification: Assessees must be diligent in classifying their assets into the correct blocks to apply the appropriate depreciation rate. Misclassification can lead to incorrect deductions and potential scrutiny from tax authorities.  
• Strategic Planning: While the rates are stable, assessees can still engage in strategic tax planning by timing capital expenditures. Investing in assets with higher depreciation rates, such as computers or renewable energy equipment, can provide a significant tax advantage by reducing taxable income more quickly and supporting a company’s investment objectives.
