Deferred Tax Assets & Liabilities
Why a profitable company can owe the tax department far less than its P&L 'tax expense' suggests — and why a loss-making company can still show a tax expense on its books.
In plain English
Imagine a company buys a ₹10 crore machine. For its own financial statements, it depreciates the machine over 10 years using the Straight-Line Method — ₹1 crore a year, as covered in the Depreciation Methods article. But the Income Tax Act allows, and the company chooses to use, ACCELERATED depreciation for tax purposes — say, ₹2.5 crore in Year 1. In Year 1, the company's REPORTED profit is based on ₹1 crore of depreciation, but the ACTUAL TAX BILL it pays is based on ₹2.5 crore of depreciation — meaning it pays less tax THIS year than its reported profit would suggest, with a bigger tax bill effectively deferred to later years, when the tax depreciation runs out but book depreciation continues. Deferred tax accounting exists to make sure the P&L's 'tax expense' line reflects the TRUE, eventual tax cost of this year's reported profit — not just the cheque actually written to the tax department this year.
Words you'll need first
Arises when a company has paid LESS tax this year than its reported accounting profit would suggest — exactly the accelerated-depreciation example above — because that gap is expected to reverse and result in MORE tax being paid in future years. It's recorded as a liability because it represents extra tax the company will genuinely have to pay later, even though no tax authority has sent a bill for it yet.
The mirror image: arises when a company has effectively paid or will pay MORE tax now than its accounting profit suggests, or when it's carrying forward tax LOSSES from earlier loss-making years that can reduce future tax bills. It's recorded as an asset because it represents a genuine future tax saving — but ONLY if the company can demonstrate it's probable enough future taxable profit will exist to use that saving; a company with no realistic path back to profitability generally can't recognise a DTA for its losses, no matter how large those losses are.
A worked example, with numbers
| Item | Year 1 | Year 2 |
|---|---|---|
| Profit before depreciation & tax | ₹20 cr | ₹20 cr |
| Book depreciation (for reported profit) | ₹1 cr | ₹1 cr |
| Reported (book) profit before tax | ₹19 cr | ₹19 cr |
| Expected tax expense @ 25% of book profit | ₹4.75 cr | ₹4.75 cr |
| Tax depreciation (for actual tax return) | ₹2.5 cr | ₹1.875 cr |
| Actual cash tax paid @ 25% of taxable profit | ₹4.375 cr | ₹4.53 cr |
| Deferred tax liability created | +₹0.375 cr | +₹0.22 cr |
- In Year 1, the company's P&L shows a ₹4.75 crore tax expense — but it only actually pays ₹4.375 crore in cash tax, because accelerated tax depreciation reduced its taxable profit below its reported profit.
- The ₹0.375 crore gap doesn't disappear — it's booked as a Deferred Tax Liability, a genuine future obligation, because in later years, once tax depreciation runs out while book depreciation continues, taxable profit will overtake reported profit, and the company will pay MORE cash tax than its P&L tax expense, gradually reversing this liability.
- This is exactly why a company's reported 'tax expense' and its actual cash taxes paid (visible in the cash flow statement) are very often two different numbers — neither is wrong, they simply answer different questions.
- If, instead of a profitable, capital-investing company, this were a company with large accumulated LOSSES, the same logic would run in reverse: it might recognise a Deferred Tax Asset today, reflecting the tax saving it expects once it returns to profitability — but only if that return to profitability is genuinely probable.
What it does to the financial statements
Impact on the P&L
- The P&L's 'Tax Expense' line is not simply the cash tax paid to the government that year — it includes both current tax (the actual cash liability) and a deferred tax component, designed to match the total tax charge to the accounting profit reported for the period.
- A large swing in deferred tax, such as from a change in tax rates announced by the government (which requires ALL existing deferred tax balances to be revalued at the new rate), can create a one-off, sometimes sizeable, non-cash tax expense or credit unrelated to that year's operating performance.
- A company can show a POSITIVE reported profit before tax but a NET LOSS after tax, or vice versa, purely because of a large deferred tax movement, independent of the underlying operating business.
- Recognising a Deferred Tax Asset on carried-forward losses, when a company turns the corner from losses to sustained profitability, can create a one-off boost to reported net profit in that transition year — worth distinguishing from genuine operational improvement.
Impact on the Balance Sheet
- Deferred Tax Liabilities and Deferred Tax Assets sit on the balance sheet as non-current items, typically disclosed net if they relate to taxes levied by the same authority and the company has a legal right to offset them.
- A large Deferred Tax Liability is common, and not inherently a red flag, for capital-intensive companies that have consistently used accelerated tax depreciation — it broadly represents future tax the company will progressively pay as its capex cycle matures.
- A large, UNRECOGNISED potential Deferred Tax Asset, visible in the notes even though it doesn't appear as an actual balance sheet asset, is common for companies that have been through a prolonged loss-making period — a real, valuable future tax shield that will only show up on the balance sheet once a probable, sustained return to profitability can be demonstrated.
- Because DTA recognition depends on management's judgement about future profitability, it's an area worth scrutinising — recognising a large DTA prematurely can overstate both reported assets and reported profit in the year of recognition.
Which standard covers this
In India this is governed by Ind AS 12 – Income Taxes, notified under the Companies (Indian Accounting Standards) Rules and applicable to companies that follow Ind AS, using a 'balance sheet' approach that compares the tax base of assets and liabilities to their accounting carrying values to compute temporary differences.
How it's recognised globally
Globally, the equivalent is IAS 12, and Ind AS 12 mirrors its balance-sheet approach and core temporary-difference logic closely. Under US GAAP, equivalent guidance sits in ASC 740, sharing the same fundamental principle — recognise deferred tax for temporary differences between book and tax treatment — though detailed rules for specific situations, such as accounting for uncertain tax positions and some technical aspects of DTA recognition thresholds, differ enough in the fine print that deferred tax balances for economically similar companies can genuinely differ between an Indian and a US GAAP filer. This is a technical, judgement-heavy corner of accounting worldwide, and one where genuine professional disagreement between auditors and tax specialists isn't unusual.
Real example — Indian listed company
Vodafone Idea is also one of the clearest Indian illustrations of deferred tax at the more dramatic end of the spectrum, this time on the Deferred Tax ASSET side. Given the company's prolonged, large accumulated losses in recent years, linked partly to the AGR dues dispute covered in the Provisions & Contingent Liabilities article, it has carried forward substantial tax losses that could, in principle, shield future profits from tax for years once the company returns to sustained profitability. But because recognising a Deferred Tax Asset requires genuine confidence that future taxable profits will actually materialise, companies in Vodafone Idea's position typically recognise little or none of this potential tax asset on the balance sheet, even though the underlying carried-forward losses are real and disclosed in the notes. This is a useful, real illustration of the judgement embedded in deferred tax accounting: the same accumulated losses that represent a genuine, potentially valuable future tax shield for a company confident of returning to profitability represent essentially nothing on the balance sheet for a company whose path back to sustained profits remains genuinely uncertain — the accounting difference lies entirely in that probability judgement, not in the size of the underlying losses themselves.
