Key Concepts: Deferred Tax Assets (DTA) & Deferred Tax Liabilities (DTL)
- DTL: Arises when the carrying amount of an asset is greater than its tax base (or a liability’s carrying amount is less than its tax base), creating future taxable income.
- DTA: Arises when the carrying amount of an asset is less than its tax base (or a liability’s carrying amount is greater than its tax base), creating future tax deductions.
Methodology for Adjusting Entries
Instead of reversing prior-period DTAs/DTLs, we determine the movement from opening to closing balances and record that movement as a journal entry.
- Movement in DTA = Closing DTA – Opening DTA
- Movement in DTL = Closing DTL – Opening DTL
This ensures that the final recorded DTA and DTL balances align with the calculated closing amounts.
Required Inputs
- Account Name
- Carrying Amount
- Tax Base
- Tax Rate
- Opening DTA and DTL
- Calculated Temporary Differences (Taxable or Deductible)
- Closing DTA and DTL
Deriving Journal Entries from Movements
- DTL Movements:
- If Closing DTL > Opening DTL:
Dr Income Tax Expense / Cr Deferred Tax Liability (Increase in future tax payable) - If Closing DTL < Opening DTL:
Dr Deferred Tax Liability / Cr Income Tax Expense (Decrease in future tax payable)
- If Closing DTL > Opening DTL:
- DTA Movements:
- If Closing DTA > Opening DTA:
Dr Deferred Tax Asset / Cr Income Tax Expense (Increase in future tax benefit) - If Closing DTA < Opening DTA:
Dr Income Tax Expense / Cr Deferred Tax Asset (Decrease in future tax benefit)
- If Closing DTA > Opening DTA:
General Causes of Temporary Differences
- DTLs often from assets depreciating slower for accounting than for tax, or revaluations not yet taxed.
- DTAs often from provisions, impairments, or unearned revenue recognized earlier for tax than for accounting.
Determining Temporary Differences
- For Assets:
- Carrying Amount > Tax Base ⇒ Taxable Temporary Difference ⇒ DTL
- Carrying Amount < Tax Base ⇒ Deductible Temporary Difference ⇒ DTA
- For Liabilities:
- Carrying Amount > Tax Base ⇒ Deductible Temporary Difference ⇒ DTA
- Carrying Amount < Tax Base ⇒ Taxable Temporary Difference ⇒ DTL
Tax Base
- Defined by tax law, it’s the amount that will be deductible or taxable in the future when the asset’s benefits are realized or the liability is settled.
Practical Steps
- Determine each account’s carrying amount and tax base.
- Identify whether the difference is taxable (leads to DTL) or deductible (leads to DTA).
- Apply the tax rate to find the corresponding DTA or DTL.
- Compare closing DTA/DTL to the opening DTA/DTL.
- Record the movement via the appropriate journal entry.
This approach ensures accurate and efficient updating of the related accounting system for deferred tax items.
