Deferred Tax Asset & Liability Calculator
A deferred tax calculator converts the gap between book profit and taxable profit into the deferred tax asset (DTA) or deferred tax liability (DTL) that has to sit on the balance sheet. The gap arises because accounting standards and the Income-tax Act recognise the same income or expense in different years: depreciation, provisions for gratuity and leave encashment, expenditure allowed only on payment, and carried-forward losses are the usual culprits.
Two frameworks operate in India. Entities on Indian GAAP follow AS 22, Accounting for Taxes on Income, which works on the income statement approach and measures timing differences, that is, differences that originate in one year and reverse in later years. Entities on Ind AS follow Ind AS 12, Income Taxes, which works on the balance sheet approach and measures temporary differences, the difference between the carrying amount of an asset or liability and its tax base. The two usually give the same answer for depreciation, but they diverge on revaluations, business combinations and items routed through other comprehensive income, which Ind AS 12 captures and AS 22 does not.
From tax year 2026-27 the computation feeding the tax base comes from the Income-tax Act, 2025. Depreciation now sits in section 33 (section 32 of the 1961 Act) and unabsorbed depreciation in section 33(11) (section 32(2)), while business loss carry-forward is in section 112 (section 72). The rate you apply is the rate you expect to be in force when the difference reverses, so a company that has opted for the 22 per cent concessional regime in section 200 (section 115BAA) measures deferred tax at that rate, not at 30 per cent.

- Deferred tax assets and liabilities are never discounted to present value under either AS 22 or Ind AS 12.
- A deferred tax asset needs reasonable certainty of sufficient future taxable income under AS 22, or the probable test under Ind AS 12.
- Offset the asset against the liability only where both relate to the same taxable entity and the same tax authority.
The formula
Deferred Tax = (Book Base − Tax Base) × Applicable Tax Rate (including surcharge and cess)
- Book Base
- Carrying amount of the asset or liability in the financial statements, or book profit for the AS 22 income statement approach.
- Tax Base
- Written down value or amount attributed to the same item under the Income-tax Act, 2025, for example the tax WDV of a block of assets under section 33.
- Applicable Tax Rate
- The enacted or substantively enacted rate expected to apply when the difference reverses, grossed up for surcharge and the 4 per cent health and education cess.
- DTL
- Arises where tax base is lower than book base, that is, the deduction has already been taken for tax and tax will be higher in future years.
- DTA
- Arises where tax base is higher than book base, that is, the deduction is still to come and future tax will be lower.
Deferred tax assets and liabilities are never discounted to present value under either AS 22 or Ind AS 12.
How to calculate it
- 1
Decide which framework applies
Companies required to follow Ind AS apply Ind AS 12 and the balance sheet approach. Other companies and non-corporate entities on Indian GAAP apply AS 22 and the timing difference approach. Fix this first, because the list of items you pick up differs.
- 2
Build the difference schedule
For every asset and liability, set the carrying amount against the tax base. The largest item is almost always the fixed asset block: book WDV under Schedule II of the Companies Act, 2013 against tax WDV under section 33 of the Income-tax Act, 2025. Add provisions, section 43B type items allowed only on payment, and carried-forward losses.
- 3
Classify each difference
Mark each as taxable (gives a DTL) or deductible (gives a DTA). Permanent differences, such as expenditure that is never allowable or income that is permanently exempt, are excluded entirely. They affect the effective tax rate, not deferred tax.
- 4
Apply the right tax rate
Use the rate expected when the item reverses, grossed up for surcharge and cess. A domestic company under section 200 (115BAA) works at 22 per cent plus 10 per cent surcharge plus 4 per cent cess, an effective 25.168 per cent. A company still on the default regime uses 30 per cent plus its applicable surcharge and cess.
- 5
Test the DTA for recognition
AS 22 allows a DTA only where there is reasonable certainty of sufficient future taxable income, and raises the bar to virtual certainty supported by convincing evidence where the DTA arises from unabsorbed depreciation or carried-forward losses. Ind AS 12 uses a single probable test but requires convincing other evidence where there is a history of recent losses. Business plans and forecasts on their own do not establish virtual certainty.
- 6
Net off and disclose
Offset DTA against DTL only where they relate to the same taxable entity and the same governing tax authority, present the net figure as a non-current item, and disclose the components and the reconciliation between the expected and actual tax expense.
Common differences and the deferred tax they create
| Item | Nature of difference | Deferred tax created |
|---|---|---|
| Tax depreciation under section 33 exceeds Schedule II depreciation | Taxable | DTL |
| Provision for gratuity or leave encashment not yet paid | Deductible | DTA |
| Statutory dues and similar items allowed only on actual payment | Deductible | DTA |
| Unabsorbed depreciation carried forward under section 33(11) | Deductible | DTA, only on virtual certainty under AS 22 |
| Business loss carried forward under section 112 | Deductible | DTA, only on virtual certainty under AS 22 |
| Expenditure permanently disallowed, or permanently exempt income | Permanent | None |
Worked example
- Book WDV of fixed asset block
- ₹20,00,000
- Tax WDV of the same block under section 33
- ₹14,00,000
- Provision for gratuity not yet paid
- ₹3,00,000
- Applicable rate, company under section 200 (115BAA)
- 25.168% (22% + 10% surcharge + 4% cess)
- Taxable temporary difference on the block = ₹20,00,000 − ₹14,00,000 = ₹6,00,000
- DTL on the block = ₹6,00,000 × 25.168% = ₹1,51,008
- Deductible temporary difference on gratuity provision = ₹3,00,000
- DTA on the provision = ₹3,00,000 × 25.168% = ₹75,504
- Net position = ₹1,51,008 − ₹75,504 = ₹75,504
Net deferred tax liability = ₹75,504
