Computers, laptops, and their operating systems have a limited lifespan and become obsolete over time. Businesses in India claim depreciation on computers at a rate of 40% using the Written Down Value (WDV) method under Section 32 of the Income Tax Act (ITA), 1961.
Key highlights of this provision include:
- Broad Applicability: The provision covers desktop systems, laptops, and software.
- Tax Benefits: Claiming this capital expense allows companies to reduce their taxable income.
- Accounting for Wear and Tear: It properly accounts for the natural wear and tear of technological assets over time.
H2: How do you calculate the depreciation on computer for tax purposes?
The ITA groups business assets into "blocks." Computers and software form a specific block eligible for the accelerated 40% WDV rate. The exact tax calculation depends heavily on the date the equipment is put to active use during the financial year:
- 180 days or more: When you purchase and use the equipment for 180 days or more in a financial year, the full 40% rate applies.
- Less than 180 days: Businesses acquiring and deploying the machine for less than 180 days in the year of purchase can only claim half the applicable rate (making the effective rate 20% for that initial year).
- Carry forward: The balance simply carries forward to the subsequent block for future deductions.
What are the Companies Act guidelines for computer life span?
Financial reporting follows entirely different regulatory rules compared to annual tax filings. Schedule II of the Companies Act, 2013, requires organisations to calculate depreciation based on the asset's useful life rather than applying a fixed statutory percentage.
You must allocate the cost of the hardware over its prescribed useful lifespan. Here are the useful life categories prescribed for technology assets:
- Six years: Servers and heavy computer networks.
- Three years: End-user devices like desktop machines and laptops.
For internal accounting books, companies can choose either:
- The Straight Line Method (SLM)
- The Written Down Value (WDV) method
Note: The chosen accounting method must reflect the pattern of future economic benefits expected from the hardware.

Which peripheral devices qualify for the higher computer depreciation rate?
Classification disputes routinely arise regarding printers, scanners, and Uninterruptible Power Supply (UPS) systems. Judicial rulings have clarified that equipment functioning alongside a computer as an integrated system qualifies for the 40% rate.
Eligible for the 40% rate (Computer Assets):
- Printers and scanners directly connected to the main operating system
- UPS equipment used exclusively to support computer hardware
- Customised and packaged business software programmes
Eligible for the 15% rate (General Plant and Machinery):
- EPABX communication systems
- Mobile phones
- iPads and standalone communication devices
Does software qualify for depreciation on computer hardware rates?
Many business owners wonder if intangible technology investments receive the same tax treatment as physical machines. The taxation department treats these intangible assets exactly like physical hardware for depreciation purposes.
- Eligible Software: Any computer programme recorded on a disc, tape, or storage device counts as software. Businesses can claim the 40% WDV rate on software licences, Enterprise Resource Planning (ERP) systems, and operating systems.
- Revenue Expenditures: Annual software maintenance contracts and renewal fees represent revenue expenditures, not capital assets. You can deduct these recurring expenses entirely in the year they are incurred.
