Amortization

Definition

Everyone understands that a Rs 40 lakh machine loses value over time, that's depreciation. But what about the Rs 15 lakh you spent on a software licence that's valid for 5 years? Or the Rs 2 crore patent your pharma company acquired? These are intangible assets, and spreading their cost over the years they generate economic benefit is amortization. Same concept as depreciation, different asset class. The charge typically runs straight-line (cost minus residual value, divided by useful life) hitting the P&L each period while the asset's carrying value on the balance sheet declines accordingly.

Ind AS 38 (India's version of IAS 38) draws a critical line: intangible assets with finite useful lives get amortized; those with indefinite useful lives (certain brand names, or goodwill from acquisitions under Ind AS 103) get tested annually for impairment instead. The Companies Act, 2013, Schedule II doesn't prescribe specific amortization rates for intangibles, leaving it to management judgment guided by Ind AS. On the tax side, Section 32(1)(ii) of the Income Tax Act allows depreciation on intangible assets (patents, copyrights, trademarks, know-how, licences) at 25% on written-down value basis. The gap between book amortization and tax depreciation creates deferred tax entries that auditors scrutinise closely.

There's a completely separate meaning of "amortization" that comes up equally often: loan repayment schedules. When your company takes a Rs 1 crore term loan for 5 years, the amortization schedule shows exactly how each EMI splits between interest (heavier in early months) and principal (heavier later). This matters because the interest component is deductible under Section 36(1)(iii), and the split must be correctly reflected in your books for accurate TDS and tax computations. Confusingly, the same word means two very different things depending on context, asset cost allocation versus loan repayment mechanics.

Key Points

• Amortization spreads intangible asset costs (patents, software, licences) over their useful life: the intangible equivalent of depreciation.
• Ind AS 38: finite-life intangibles are amortized; indefinite-life intangibles (including acquisition goodwill) get annual impairment testing instead.
• Income Tax Act Section 32(1)(ii) allows 25% WDV depreciation on intangible assets: often different from book amortization rates.
• Loan amortization schedules show the interest/principal split in each EMI. Interest is tax-deductible; the split must be accurately recorded.
• Straight-line is the default method: (cost minus residual value) divided by useful life equals the annual charge.
• Goodwill from business combinations under Ind AS 103 is impairment-tested, not amortized: a common exam and audit question.
