Temporary difference is one of the most important ideas in deferred tax accounting. It explains why the accounting value of an asset or liability can differ from its tax value, and why that mismatch creates deferred tax assets or deferred tax liabilities. If you understand a temporary difference, you can read tax notes more intelligently, interpret reported tax expense better, and avoid confusing accounting tax expense with actual cash tax paid.

1. Term Overview

Item	Details
Official Term	Temporary Difference
Common Synonyms	Temporary book-tax difference, deferred tax difference, taxable temporary difference, deductible temporary difference
Alternate Spellings / Variants	Temporary-Difference
Domain / Subdomain	Finance / Accounting and Reporting
One-line definition	A temporary difference is the difference between the carrying amount of an asset or liability in financial statements and its tax base, which will create taxable or deductible amounts in future periods.
Plain-English definition	It means the same item has one value for accounting and another for tax today, and that gap is expected to affect tax later.
Why this term matters	Temporary differences are the foundation of deferred tax accounting and are critical for reporting tax expense, analyzing earnings quality, valuing companies, and understanding future tax consequences.

Important note:
“Timing difference” is often used informally as if it means the same thing, but in modern accounting they are not always identical. A temporary difference is the broader and more precise term in current deferred tax standards.

2. Core Meaning

A temporary difference exists because accounting rules and tax rules do not always recognize or measure items in the same way or at the same time.

What it is

It is the gap between:

• the carrying amount of an asset or liability in the financial statements, and
• the tax base of that same asset or liability under tax law.

Why it exists

It exists because tax systems and accounting standards have different objectives:

• Accounting tries to show economic performance and financial position.
• Tax law tries to determine taxable income according to legal rules and policy goals.

Because of that, the same transaction may be:

• expensed faster for tax than for accounting,
• recognized earlier in accounting than for tax,
• measured at fair value for accounting but not for tax,
• deductible only when cash is paid, even if accounting recognizes the expense earlier.

What problem it solves

Without the temporary difference concept, financial statements would miss the future tax effects of current balance sheet items.

It solves the problem of matching future tax consequences to current accounting balances. That is why temporary differences are used to calculate:

• Deferred tax liabilities (DTLs), and
• Deferred tax assets (DTAs).

Who uses it

Temporary difference is used by:

• accountants
• auditors
• tax teams
• CFOs and controllers
• financial analysts
• investors
• credit analysts and lenders
• regulators and standard-setters
• students preparing for exams in accounting and finance

Where it appears in practice

You see temporary differences in:

• deferred tax calculations
• financial statement tax notes
• audit workpapers
• management reporting
• valuation models
• M&A due diligence
• tax provision processes
• board and lender reporting

3. Detailed Definition

Formal definition

In modern financial reporting, a temporary difference is the difference between the carrying amount of an asset or liability in the statement of financial position and its tax base.

Technical definition

A temporary difference represents a future tax consequence that will arise when:

• the carrying amount of an asset is recovered, or
• the carrying amount of a liability is settled.

That future consequence may produce:

• taxable amounts in future periods, or
• deductible amounts in future periods.

This is why temporary differences are classified as:

• taxable temporary differences, usually giving rise to a deferred tax liability
• deductible temporary differences, usually giving rise to a deferred tax asset

Operational definition

In practice, you identify a temporary difference by following this logic:

1. Identify the asset or liability on the balance sheet.
2. Determine its carrying amount under accounting standards.
3. Determine its tax base under applicable tax law.
4. Compare the two amounts.
5. Decide whether recovery or settlement will lead to taxable or deductible amounts in the future.
6. Measure the related deferred tax, subject to recognition rules and exceptions.

Context-specific definitions

Under IFRS and Ind AS

The term is used in the standard deferred tax model and is central to deferred tax accounting. The focus is balance-sheet-based: compare carrying amount with tax base.

Under US GAAP

The concept is also central, though application details differ in places. Temporary differences are used in the asset-and-liability approach to deferred taxes under the income tax accounting framework.

Under older or legacy frameworks

Some older accounting frameworks emphasized timing differences instead. That approach focused more on income statement timing and could miss some balance-sheet-based differences, such as some revaluation or acquisition-related items.

4. Etymology / Origin / Historical Background

The term comes from the idea that the difference is temporary, not permanent.

Origin of the term

• Temporary means the difference is expected to reverse in a future period.
• Difference refers to the mismatch between accounting value and tax value.

So the term literally means: a mismatch that exists now but is expected to unwind later.

Historical development

Earlier deferred tax accounting often focused on timing differences. These were differences between accounting income and taxable income that arose in one period and reversed in another.

Over time, standard-setters moved toward a balance sheet approach, which asks:

• What is the carrying amount?
• What is the tax base?
• What future tax effect follows from that difference?

This approach is broader and more powerful.

How usage changed over time

The term evolved from a narrower idea of “profit timing” to a broader idea of “balance sheet tax consequences.”

That change mattered because it captured items such as:

• fair value adjustments
• revaluation gains
• business combination adjustments
• certain lease-related balances
• other differences that do not fit neatly into simple timing models

Important milestones

Broadly important milestones include:

• the move from timing-difference models to asset-liability or balance-sheet-based models
• revised international standards emphasizing temporary differences
• alignment in many jurisdictions with modern deferred tax frameworks
• continuing updates to recognition exceptions and disclosure requirements

5. Conceptual Breakdown

Temporary difference is easiest to understand when broken into its core building blocks.

5.1 Carrying Amount

Meaning:
The amount at which an asset or liability is recognized in the financial statements.

Role:
This is the accounting number.

Interaction:
It is compared with the tax base to identify the temporary difference.

Practical importance:
If the carrying amount changes because of depreciation, impairment, revaluation, or amortization, the temporary difference may also change.

5.2 Tax Base

Meaning:
The amount attributed to an asset or liability for tax purposes.

Role:
This is the tax number.

Interaction:
The tax base may differ from the carrying amount because tax law may allow different deductions, timing, or measurement.

Practical importance:
A wrong tax base leads directly to a wrong deferred tax calculation.

5.3 Temporary Difference

Meaning:
The gap between carrying amount and tax base.

Role:
This is the source amount used to determine deferred tax.

Interaction:
It becomes meaningful only when you ask what happens when the asset is recovered or the liability is settled.

Practical importance:
Not every book-tax difference is temporary. Some are permanent and do not reverse.

5.4 Taxable Temporary Difference

Meaning:
A temporary difference that will result in taxable amounts in future periods.

Role:
Usually creates a deferred tax liability.

Interaction:
Common when an asset’s carrying amount exceeds its tax base.

Practical importance:
It signals taxes postponed to future periods.

Example:
Tax depreciation is faster than accounting depreciation. The tax base falls more quickly than the carrying amount. Future tax deductions become smaller, so future taxable income becomes higher.

5.5 Deductible Temporary Difference

Meaning:
A temporary difference that will result in deductible amounts in future periods.

Role:
Usually creates a deferred tax asset.

Interaction:
Common when an expense is recognized in accounting before it becomes tax-deductible.

Practical importance:
It signals future tax relief, subject to recognition tests.

Example:
A warranty provision is recognized now for accounting, but tax deduction is allowed only when claims are paid later.

5.6 Reversal

Meaning:
The process by which a temporary difference disappears over time.

Role:
It explains why the difference is temporary rather than permanent.

Interaction:
As assets are recovered or liabilities settled, the carrying amount and tax base move toward each other or the tax consequence materializes.

Practical importance:
Analysts often care not just about the amount of deferred tax, but also when and how it may reverse.

5.7 Tax Rate Used for Measurement

Meaning:
The applicable tax rate expected to apply when the difference reverses.

Role:
It converts the temporary difference into a deferred tax amount.

Interaction:
A change in tax rate changes the value of the deferred tax asset or liability.

Practical importance:
Rate changes can create significant gains or losses in reported tax expense even without immediate cash tax impact.

5.8 Recognition of Deferred Tax

Meaning:
Not every deductible amount becomes a recognized deferred tax asset automatically under every framework.

Role:
Recognition rules determine whether the deferred tax effect is recorded.

Interaction:
Taxable temporary differences are often recognized more directly than deductible ones, because deductible ones depend on future taxable profit or recoverability assessments.

Practical importance:
A large theoretical deductible temporary difference may not become a fully recognized deferred tax asset.

5.9 Quick Sign Guide

Item Type	If Carrying Amount > Tax Base	If Carrying Amount < Tax Base
Asset	Usually taxable temporary difference	Usually deductible temporary difference
Liability	Usually deductible temporary difference	Usually taxable temporary difference

Caution:
This sign guide is helpful, but the real test is always the future tax consequence of recovery or settlement.

6. Related Terms and Distinctions

Related Term	Relationship to Main Term	Key Difference	Common Confusion
Tax Base	Input to temporary difference	Tax base is the tax value; temporary difference is the gap between tax base and carrying amount	People sometimes treat tax base as the deferred tax amount
Carrying Amount	Input to temporary difference	Carrying amount is the accounting value; temporary difference is the mismatch	“Book value” and carrying amount are often used interchangeably
Deferred Tax Asset	Result of some temporary differences	A DTA is the accounting consequence; the temporary difference is the underlying cause	Many readers confuse the difference itself with the balance recorded

9. Real-World Scenarios

A. Beginner Scenario

Background:
A small company buys machinery for 100,000.

Problem:
Accounting depreciation is 20,000 in year one, but tax depreciation is 40,000.

Application of the term:
After year one:

• carrying amount = 80,000
• tax base = 60,000
• temporary difference = 20,000

Because future taxable income will be higher when tax deductions slow down, this is a taxable temporary difference.

Decision taken:
The accountant records a deferred tax liability.

Result:
Tax expense in the financial statements includes a deferred component, not just current tax.

Lesson learned:
Cash tax today and accounting tax expense today are not always the same.

B. Business Scenario

Background:
A manufacturer records a warranty provision of 500,000.

Problem:
Tax deduction is allowed only when warranty claims are actually paid.

Application of the term:
The warranty liability exists in accounting now, but the tax benefit arrives later. That creates a deductible temporary difference.

Decision taken:
Management evaluates whether future taxable profits are likely enough to support recognition of a deferred tax asset.

Result:
A deferred tax asset may be recognized, improving the balance sheet and aligning tax expense with the economic cost.

Lesson learned:
A deductible temporary difference has value only if it can likely be used.

C. Investor / Market Scenario

Background:
An investor is analyzing a capital-intensive company with strong earnings but low cash taxes.

Problem:
The investor wants to know whether low cash taxes are permanent or temporary.

Application of the term:
The company has large deferred tax liabilities from accelerated tax depreciation. That means current cash tax is low because deductions were taken early, but future taxes may rise as the differences reverse.

Decision taken:
The investor adjusts the valuation model and does not assume the unusually low cash tax rate will continue forever.

Result:
The investor produces a more realistic free cash flow forecast.

Lesson learned:
Temporary differences help distinguish sustainable tax benefits from timing effects.

D. Policy / Government / Regulatory Scenario

Background:
A government changes the corporate tax rate from 30% to 25%.

Problem:
Companies already have existing deferred tax assets and liabilities measured at the old rate.

Application of the term:
The temporary differences themselves may not change immediately, but the tax rate applied to them does.

Decision taken:
Companies remeasure deferred tax balances using the new applicable rate, following the relevant accounting framework.

Result:
Reported tax expense may change significantly in the current period even though current cash tax may not change immediately.

Lesson learned:
Deferred tax is sensitive not only to differences in amount, but also to changes in tax law.

E. Advanced Professional Scenario

Background:
A listed property company carries investment property at fair value. Tax law taxes gains only on disposal.

Problem:
The accounting carrying amount rises sharply after revaluation, while the tax base remains much lower.

Application of the term:
The company identifies a large taxable temporary difference. It must then determine the appropriate measurement based on the expected manner of recovery and applicable tax rules.

Decision taken:
A deferred tax liability is recognized and disclosed, with careful judgment around the tax rate and the recovery assumption.

Result:
Users of the financial statements see that part of the increase in net assets has an associated future tax effect.

Lesson learned:
Fair value gains may improve accounting numbers today, but they can also create substantial deferred tax obligations.

10. Worked Examples

10.1 Simple Conceptual Example

A machine has:

• carrying amount: 80
• tax base: 60

Temporary difference:

• 80 – 60 = 20

Because the machine’s accounting value is higher than its tax value, future taxable amounts will usually be higher when the asset is recovered. This is a taxable temporary difference.

10.2 Practical Business Example

A company records a warranty liability of 50.

Tax deduction is available only when claims are paid.

• carrying amount of liability: 50
• tax base of liability: 0
• difference: 50

For liabilities, this situation usually creates a deductible temporary difference, because future payment will create a tax deduction.

If tax rate = 30%, the potential deferred tax asset is:

• 50 × 30% = 15

Caution:
Recognition depends on whether future taxable profit is expected to be available under the applicable accounting framework.

10.3 Numerical Example: Step-by-Step

A company buys equipment for 100,000.

At year-end:

• accounting depreciation = 20,000
• tax depreciation = 40,000
• tax rate = 30%

Step 1: Calculate carrying amount

Carrying amount = 100,000 – 20,000 = 80,000

Step 2: Calculate tax base

Tax base = 100,000 – 40,000 = 60,000

Step 3: Calculate temporary difference

Temporary difference = 80,000 – 60,000 = 20,000

Step 4: Classify the difference

For an asset, carrying amount greater than tax base usually means a taxable temporary difference.

Step 5: Measure deferred tax

Deferred tax liability = 20,000 × 30% = 6,000

Step 6: Interpret

The company received larger tax deductions earlier than accounting depreciation. So it pays less tax now, but more tax later.

10.4 Advanced Example: Revaluation

A property has:

• carrying amount before revaluation: 350,000
• carrying amount after revaluation: 500,000
• tax base: 350,000
• tax rate: 25%

Step 1: Temporary difference

500,000 – 350,000 = 150,000

Step 2: Classification

This is usually a taxable temporary difference.

Step 3: Deferred tax liability

150,000 × 25% = 37,500

Step 4: Interpretation

The revaluation gain increases accounting net assets, but tax law may still treat the asset at a lower base. The difference implies future taxable amounts when recovered, subject to local tax rules and recovery assumptions.

11. Formula / Model / Methodology

Temporary difference does not have a single famous ratio like EPS or ROE, but it does have a standard method.

11.1 Formula Name: Temporary Difference Method

Formula:

Temporary Difference = Carrying Amount - Tax Base

Where:

• Carrying Amount = accounting value in financial statements
• Tax Base = value attributed to the item for tax purposes

11.2 Formula Name: Deferred Tax Liability

Formula:

Deferred Tax Liability = Taxable Temporary Difference × Applicable Tax Rate

Where:

• Taxable Temporary Difference = future taxable amount created by the difference
• Applicable Tax Rate = enacted or substantively enacted rate expected to apply when the difference reverses, depending on framework

11.3 Formula Name: Deferred Tax Asset

Formula:

Deferred Tax Asset = Deductible Temporary Difference × Applicable Tax Rate

Where:

• Deductible Temporary Difference = future deductible amount created by the difference
• Applicable Tax Rate = relevant future tax rate
• Recognition filter = under some frameworks, recognition is limited by recoverability or probable taxable profit tests

11.4 Interpretation

• If the difference creates future tax payable, it leads to a DTL.
• If it creates future tax relief, it leads to a DTA.

11.5 Sample Calculation

Suppose:

• carrying amount of equipment = 800
• tax base = 500
• tax rate = 25%

Then:

1. Temporary difference = 800 – 500 = 300
2. This is usually a taxable temporary difference
3. DTL = 300 × 25% = 75

11.6 Common Mistakes

• Using the wrong tax base
• Treating all book-tax differences as temporary
• Ignoring the liability-versus-asset distinction
• Using the current blended effective tax rate instead of the applicable statutory rate framework requires
• Forgetting to remeasure deferred taxes when tax rates change
• Recognizing a DTA without enough evidence of future taxable profit
• Ignoring special tax rules for recovery through sale versus use

11.7 Limitations

• The formula is simple, but the underlying tax law may be complex.
• Recoverability of DTAs can involve substantial judgment.
• Reversal timing may be uncertain.
• Measurement can vary by jurisdiction and by the expected manner of recovery.

12. Algorithms / Analytical Patterns / Decision Logic

Temporary difference accounting does not rely on a trading algorithm, but it does use structured decision logic.

12.1 Five-Step Identification Framework

What it is:
A practical workflow to identify temporary differences.

Why it matters:
It reduces classification errors and missed items.

When to use it:
At every reporting date, especially during close and audit.

Steps:

1. List all significant assets and liabilities.
2. Determine carrying amount under accounting standards.
3. Determine tax base under tax law.
4. Compare the two amounts.
5. Ask whether recovery or settlement creates taxable or deductible amounts.

Limitations:
The framework still depends on correct interpretation of local tax law.

12.2 Reversal Scheduling Pattern

What it is:
An analysis of when temporary differences are expected to reverse.

Why it matters:
It helps evaluate DTA recoverability, future cash taxes, and valuation effects.

When to use it:
When there are material deferred tax balances or forecasting needs.

Typical uses:

• mapping asset lives
• warranty payout periods
• lease schedules
• amortization schedules
• revaluation unwind assumptions

Limitations:
Reversal timing may change due to sales, impairments, tax law changes, or operational decisions.

12.3 Deferred Tax Asset Recoverability Test

What it is:
A judgment framework to assess whether deductible temporary differences should be recognized.

Why it matters:
A DTA that cannot likely be used should not be overstated.

When to use it:
Whenever deductible temporary differences are material, especially in loss-making entities.

Key inputs:

• forecast taxable profits
• reversal of existing taxable temporary differences
• tax planning opportunities where permitted
• expiry dates, if any
• jurisdiction-specific restrictions

Limitations:
Forecasts may be optimistic or uncertain.

12.4 Balance Sheet Review Logic

What it is:
A line-item review of every balance sheet account for book-versus-tax differences.

Why it matters:
Many temporary differences are missed when teams focus only on the income statement.

When to use it:
During tax provision preparation, M&A reviews, or control remediation.

Limitations:
It can be time-consuming without strong systems and tax mapping.

13. Regulatory / Government / Policy Context

Temporary difference is heavily shaped by accounting standards and local tax laws.

13.1 International Financial Reporting Context

Under international standards, deferred tax is generally based on temporary differences between carrying amount and tax base.

Key features typically include:

• broad balance sheet approach
• recognition of deferred tax for taxable and deductible temporary differences, subject to exceptions
• measurement using tax rates expected to apply when the asset is recovered or liability settled
• use of enacted or substantively enacted rates, depending on the framework

Common areas needing judgment:

• revalued assets
• business combinations
• leases
• provisions
• investments in subsidiaries, branches, and associates
• initial recognition exceptions

13.2 US GAAP Context

Under US GAAP, temporary differences are also fundamental to income tax accounting.

Important features include:

• asset-and-liability approach
• recognition of deferred tax effects of temporary differences and carryforwards
• use of enacted tax rates
• valuation allowance approach for deferred tax assets
• detailed disclosure requirements

13.3 India Context

In India, the modern Ind AS framework uses the temporary difference approach in line with international practice.

However, many learners still come across older material based on timing differences under legacy Indian GAAP. That can create confusion.

Practical implication:
If you are studying or working in India, always confirm whether the entity reports under:

• Ind AS, or
• another framework that may use different wording or logic

13.4 UK and EU Context

Many entities in the UK and EU reporting under IFRS or IFRS-based frameworks use the temporary difference model.

Points to verify in practice:

• whether the reporting framework is IFRS or local GAAP
• how tax rates are considered enacted or substantively enacted
• whether local tax rules create special rates for capital gains or disposals

13.5 Accounting Standards Relevance

The most relevant accounting area is deferred tax accounting. In practice, readers should study the current version of:

• the applicable deferred tax standard under IFRS or Ind AS
• the applicable income tax accounting guidance under US GAAP
• local GAAP rules if the entity does not use international standards

13.6 Taxation Angle

Temporary differences are not tax rules themselves. They are accounting interpretations of tax consequences.

That means you must verify:

• the actual tax deduction timing
• whether an item is taxable or exempt
• applicable tax rates
• restrictions on losses or deductions
• any special rules for capital items, leases, or cross-border income

13.7 Public Policy Impact

Governments often create temporary differences through policy tools such as:

• accelerated depreciation incentives
• investment allowances
• special deductions
• tax deferral rules
• rate changes

These can affect:

• current tax collections
• reported deferred tax
• corporate investment behavior
• market interpretation of earnings

14. Stakeholder Perspective

Student

A student should see temporary difference as the bridge between accounting profit and tax consequences. It is a high-value concept for exams because it connects balance sheet logic, tax expense, and disclosure.

Business Owner

A business owner may not calculate temporary differences personally, but should understand that tax expense in the accounts is not always the same as tax paid in cash. This matters for planning, dividends, and lender conversations.

Accountant

For an accountant, temporary differences are a core part of month-end, quarter-end, and year-end reporting. Errors here can materially misstate tax expense, assets, liabilities, and equity.

Investor

An investor uses temporary differences to separate:

• normal operating tax burden
• timing-driven tax benefits
• aggressive assumptions in DTAs
• one-time deferred tax effects from rate changes or revaluations

Banker / Lender

A lender cares because deferred tax balances can affect:

• net worth
• covenant calculations
• forecast cash taxes
• quality of earnings

Analyst

An analyst uses temporary differences to understand:

• effective tax rate volatility
• difference between book tax and cash tax
• sustainability of tax advantages
• acquisition accounting effects

Policymaker / Regulator

A regulator or policymaker looks at temporary differences because they reveal how tax design interacts with accounting outcomes and whether disclosures adequately explain deferred tax consequences.

15. Benefits, Importance, and Strategic Value

Why it is important

Temporary difference is important because it gives a more complete picture of the tax consequences embedded in the balance sheet.

Value to decision-making

It helps management and users of financial statements:

• estimate future tax effects
• understand non-cash tax expense
• assess earnings quality
• forecast cash flows more accurately
• judge whether profits are supported by sustainable tax positions

Impact on planning

It improves planning around:

• capital expenditure
• asset sales
• leases
• provisions
• acquisition structuring
• tax rate changes

Impact on performance analysis

It helps distinguish:

• accounting profit from taxable profit
• tax timing benefits from permanent tax savings
• current period tax expense from long-term tax burden

Impact on compliance

Good temporary difference tracking supports:

• accurate financial reporting
• smoother audits
• stronger internal controls
• better tax note disclosures

Impact on risk management

It helps identify risk related to:

• overstated DTAs
• misunderstood DTLs
• tax law changes
• hidden future tax costs
• weak close processes

16. Risks, Limitations, and Criticisms

Common weaknesses

• complex to calculate
• depends on tax law interpretation
• vulnerable to spreadsheet errors
• requires judgment on recoverability and reversal timing

Practical limitations

• tax bases are not always easy to determine
• recovery assumptions can be uncertain
• different jurisdictions apply different tax treatments
• some deferred tax balances may reverse over very long periods

Misuse cases

• using deferred tax balances to imply immediate cash tax effects
• recognizing large DTAs without robust evidence
• treating all tax note movements as operating performance
• masking tax quality issues with heavy netting or poor disclosure

Misleading interpretations

A large deferred tax asset can look positive, but it may simply reflect:

• prior losses
• delayed deductions
• uncertain future usability

A large deferred tax liability can look negative, but it may reflect:

• timing benefits already enjoyed
• revaluation adjustments
• long-dated reversals that are not immediate cash drains

Edge cases

Complex areas include:

• investments in subsidiaries and associates
• goodwill
• leases
• hybrid instruments
• fair value through profit or loss items
• cross-border structures
• special rates for disposal gains

Criticisms by experts or practitioners

Some practitioners argue that deferred tax accounting can be:

• too complex for non-specialist users
• less useful when reversal timing is highly uncertain
• sensitive to management assumptions
• difficult to compare across jurisdictions

Even so, it remains a core part of modern reporting.

17. Common Mistakes and Misconceptions

Wrong Belief	Why It Is Wrong	Correct Understanding	Memory Tip
Every book-tax difference is a temporary difference	Some differences never reverse	Only reversing differences are temporary	“Temporary means it comes back”
Temporary difference and timing difference are always identical	Modern standards use a broader balance-sheet approach	Timing difference is related, but not always the same	“Timing is narrower than temporary”
Deferred tax liability means tax is due now	DTL reflects future tax consequences, not immediate payment	It is a future-oriented accounting balance	“DTL is delayed, not due today”
Deferred tax asset is the same as cash in hand	A DTA may depend on future taxable profit	It is a potential future tax benefit, not cash today	“Asset first, cash later”
A higher carrying amount always means taxable temporary difference	That depends on whether the item is an asset or liability and on recovery/settlement	Future tax consequence determines classification	“Check the future effect, not just the sign”
Revaluations without sale have no tax effect	Revaluation can create a temporary difference even before sale	Deferred tax may arise from unrealized accounting remeasurement	“No sale does not mean no tax effect”
If a company expects profits, any DTA can be recognized	Recognition requires evidence and framework-specific tests	Recoverability must be supportable	“Hope is not evidence”
Deferred tax never changes unless the underlying asset changes	Tax rates and tax laws can remeasure deferred tax	Rate
