| Year | Opening Value (₹) | Depreciation (₹) | Closing Value (₹) |
|---|
Equal depreciation charged every year. Best for assets with uniform economic usefulness (furniture, buildings).
Annual Dep. = (Cost − Salvage) ÷ Useful Life
Higher depreciation in early years on reducing balance. Mandatory for Income Tax in India. Best for tech, vehicles.
Annual Dep. = Book Value × Rate %

WDV depreciation rates as prescribed under Section 32 of the Income Tax Act, 1961. All businesses and professionals must use these rates for tax computation.
| Asset Block | Description | WDV Rate |
|---|---|---|
| Building — Block 1 | Residential buildings (used for business) | 5% |
| Building — Block 2 | Commercial/office buildings, hotels | 10% |
| Building — Block 3 | Temporary structures | 40% |
| Furniture & Fittings | Office furniture, partitions, electrical fittings | 10% |
| Plant & Machinery — Block 1 | General plant and machinery | 15% |
| Plant & Machinery — Block 2 | Motor cars, scooters (not commercial use) | 15% |
| Plant & Machinery — Block 3 | Commercial vehicles (buses, trucks, taxis) | 30% |
| Computers & IT | Computers, laptops, printers, servers, software | 40% |
| Intangible Assets | Patents, copyrights, trademarks, know-how | 25% |
| New Mfg. Plant (Additional) | New machinery for manufacturing — additional depreciation claim | +20% (additional) |
Assets added in the second half of the year (after October 3rd) are eligible for only 50% of the normal depreciation in the year of purchase.
| Aspect | Companies Act 2013 | Income Tax Act 1961 |
|---|---|---|
| Method | SLM or WDV | WDV only (Sec 32) |
| Purpose | Financial reporting (P&L) | Tax deduction calculation |
| Asset life | Schedule II useful life | Block-wise WDV rates |
| Computer rate | SLM 33.33% (3 yr life) | WDV 40% |
| Vehicle rate | SLM 25.89% (8 yr life) | WDV 15–30% |
| Result | Two different P&Ls | Leads to deferred tax asset/liability |
Assets purchased after October 3rd (i.e., after the first half of the financial year) are eligible for only 50% of the normal WDV rate in the year of purchase under the Income Tax Act.
Under the Income Tax Act, similar assets are grouped into 'blocks'. Depreciation is calculated on the total WDV of the block, not each asset individually. Additions and disposals adjust the block value.
New plant & machinery used for manufacturing or power generation qualifies for an additional 20% depreciation in the year of purchase (10% if installed in the second half).
You cannot depreciate an asset below its residual/scrap value. Under Companies Act, if book value goes below scrap value, depreciation stops. Under IT Act, WDV theoretically never reaches zero.
