Note: In the last year, we have considered the difference amount as depreciation after keeping a closing balance of ₹1 in the asset account. We keep a balance of ₹1 to maintain the asset in books, as suggested by the Income Tax Act.
50% depreciation will be applied if the asset is put to use for less than 180 days in the first year.

Understanding Depreciation in India

Depreciation represents the reduction in an asset's value due to usage, wear and tear, obsolescence, or market changes. In India, companies must calculate depreciation for both accounting purposes (Companies Act) and tax purposes (Income Tax Act).

Straight Line Method (SLM) Vs Written Down Value (WDV)

There are two primary methods of calculating depreciation in India:

Straight Line Method (SLM)

Under SLM, the depreciation hums along at a fixed slice of the asset's starting cost every year. The result is even predictable depreciation across the asset's useful life.

Formula: Depreciation = (Original Cost × Rate of Depreciation) / 100

Best for: Assets whose values depreciate uniformly over time

Written Down Value Method (WDV)

It works on the basis of the reducing book value of the asset, whereby heftier write-offs come in the early years and smaller ones later.

Formula: Depreciation = (Opening WDV × Rate of Depreciation) / 100

Best for: Assets whose value depreciates faster during their early years

Depreciation Under Income Tax Act

The Income Tax Act specifies the rate of depreciation on various types of assets. Following are the important points of the Income Tax Act:

Depreciation for tax purposes is calculated using the written down value method.
If an asset is used for fewer than 180 days in the first year, a special half-year rule is applied for depreciation.
New plant and machinery may qualify for additional depreciation.
Simple calculations are made possible since assets are blocked together.

Depreciation Under Companies Act

Under the Companies Act, 2013, for the purpose of financial reporting, one can follow SLM or WDV. The estimated assets' lives are given in Schedule II.

Common Depreciation Rates Under Income Tax Act

Asset Type	Depreciation Rate (WDV)
Residential Buildings	5%
Commercial Buildings	10%
Furniture and Fittings	10%
Plant and Machinery	15%
Computers and Software	40%
Motor Vehicles	15% (Commercial), 20% (Personal)
Intangible Assets	25%

Additional Depreciation Benefits

To incentivize investment in new plant and machinery, extra depreciation is available under the Income Tax Act:

20% depreciation on new plant and machinery-office equipment and vehicles are excluded.
35% additional depreciation for manufacturers in notified backward areas of certain states

Frequently Asked Questions (FAQs)

What is the difference between SLM and WDV methods?

The Straight Line Method (SLM) applies depreciation equally over the asset's useful life based on the original cost. The Written Down Value (WDV) method calculates depreciation on the reducing balance, resulting in higher depreciation in earlier years and lower in later years.

When is additional depreciation applicable?

Additional depreciation is applicable only for new plant and machinery acquired and installed by a manufacturing business or a power generation/distribution business. It does not apply to office equipment, vehicles, or second-hand assets.

What is the half-year rule for depreciation?

The half-year rule stipulates that if an asset is purchased and put to use for less than 180 days in a financial year, only 50% of the regular depreciation can be claimed for that year. The full rate applies in subsequent years.

Why is there a ₹1 residual value in the depreciation table?

According to accounting principles and the Income Tax Act, it's common practice to maintain a nominal value (typically ₹1) in the books for fully depreciated assets that are still in use. This helps maintain record of the asset while acknowledging it has been fully depreciated for tax purposes.

Which depreciation method is better for tax savings?

The WDV method typically provides higher tax savings in the initial years because it allows for larger depreciation deductions early in the asset's life. However, for income tax purposes in India, you must follow the prescribed method (generally WDV) and rates specified in the Income Tax Act, regardless of which method might provide more savings.
