Compute Deferred Tax Asset (DTA) and Deferred Tax Liability (DTL) from book-vs-tax base differences. Default items pre-populated for a typical Indian company; adjust per engagement.
| Item | Book base (₹) | Tax base (₹) | Diff | Type | DTA | DTL |
|---|---|---|---|---|---|---|
| PPE — book WDV vs IT WDV | ₹15,00,000 | DTL | — | ₹3,77,550 | ||
| Provision for gratuity (allowed on payment) | ₹5,00,000 | DTL | — | ₹1,25,850 | ||
| Provision for leave encashment | ₹3,50,000 | DTL | — | ₹88,095 | ||
| Provision for bonus (43B carve-out) | ₹2,00,000 | DTL | — | ₹50,340 | ||
| Provision for doubtful debts | ₹4,00,000 | DTL | — | ₹1,00,680 | ||
| Carry-forward of unabsorbed depreciation / losses (tax base only) | ₹-20,00,000 | DTA | ₹5,03,400 | — | ||
| Total | ₹5,03,400 | ₹7,42,515 | ||||
AS 22 uses a timing-difference approach (P&L view); Ind AS 12 uses the temporary-differenceapproach (BS view). Both compute deferred tax on items where the book recognition timing differs from the tax recognition timing — depreciation (book = Sch II, tax = Section 32), provisions disallowed on book basis but allowed on payment (gratuity, leave, bonus — Section 43B), carry-forward losses.
Recoverability is the auditor’s key challenge: DTA on regular timing differences requires “reasonable certainty” of future taxable income; DTA on carry-forward losses / unabsorbed depreciation requires “virtual certainty supported by convincing evidence.” Forecasts + tax planning + history of taxable profits are the standard evidence.
Deferred tax arises because the rules for computing taxable profit differ from the rules for computing accounting profit. Items recognised in the financial statements may be recognised at a different time, or in a different amount, for tax purposes. These differences are either temporary (will reverse in future periods) or permanent (will never reverse). Only temporary differences give rise to deferred tax.
Under Ind AS 12 (Income Taxes), the balance sheet approach is followed: compare the carrying amount of each asset / liability with its tax base. The difference is a temporary difference, multiplied by the applicable tax rate to get the deferred tax. Taxable temporary differences create a Deferred Tax Liability (DTL); deductible temporary differences create a Deferred Tax Asset (DTA), subject to recoverability test (Section 5.27-5.36 of Ind AS 12).
Under AS 22 (for non-Ind AS entities), the income-statement approach was historically used (timing differences in income vs taxable income). The 2016 amendment to AS 22 added a balance sheet test for re-measurement on tax rate change. DTA is recognised only when there is "virtual certainty" of realisation if backed by losses / unabsorbed depreciation; otherwise "reasonable certainty" suffices.
A company has plant with original cost ₹100 cr, accumulated book depreciation ₹40 cr (book WDV = ₹60 cr), and accumulated tax depreciation ₹55 cr (tax WDV = ₹45 cr). Tax rate is 25.17% (Section 115BAA).
