Depreciation + Asset Register

Depreciation, computed twice — Income Tax Act beside Companies Act.

One asset, two statutes, side by side: WDV block rates with the 180-day rule and additional depreciation u/s 32(1)(iia), against Schedule II useful lives on SLM or WDV. Or maintain a full asset-wise register with Schedule III note output.

Asset particulars

Enter one asset. The same date drives both computations — day-wise pro-ration under the Companies Act, the 180-day test under the Income Tax Act.
Additional depreciation u/s 32(1)(iia) — new plant & machinery acquired and installed by an assessee engaged in manufacture or production. 20% of actual cost (10% if put to use < 180 days; balance 10% allowed in the succeeding year).

Common questions

What is the difference between Income Tax and Companies Act depreciation?

Income-tax uses block-of-asset WDV rates with the 180-day half-rate rule and additional depreciation for manufacturers; the Companies Act uses Schedule II useful lives in SLM or WDV per asset. Both are correct for their purpose — this tool computes them side by side.

What is additional depreciation under section 32(1)(iia)?

An extra 20% (10% if used under 180 days, balance next year) on new plant and machinery for manufacturers, over normal depreciation. The tool applies eligibility and carry-forward automatically.

How is depreciation calculated for an asset purchased mid-year?

Companies Act: pro-rata from the date put to use. Income-tax: full rate if used 180 days or more, half otherwise. The tool handles the day-count from your purchase date.
