1. Scenario Technical Specifications
For the financial year ending 31 December 2026, a corporation reports an accounting profit before tax of $1,000,000.
  • Statutory Enacted Tax Rate: 25%
  • Permanent Difference: The company incurred non-deductible penalties and fines of $40,000.
  • Temporary Difference Asset-Side: Financial accounting depreciation was $150,000, while accelerated tax depreciation allowed by revenue authorities was $230,000.
  • Temporary Difference Liability-Side: The company recorded an accrued warranty liability of $60,000. No tax deductions are permitted for warranties until cash is paid to clients.
    Accounting Profit Before Tax = 1000000
    Add: Non-Deductible Penalties (Permanent) = +40000
    Add: Warranty Book Expense (Temporary) = +60000
    Subtract: Excess Tax Depreciation (230000 − 150000) = −80000
    Taxable Income Basis = 1000000 + 40000 + 60000 − 80000 = 1020000
    Current Tax Liability / Expense = 1020000 × 25% = 255000
  • Step 2: Compute Deferred Tax Balances

    • Depreciation Temporary Difference (Taxable): Carrying Value > Tax Base by 80000.
      Deferred Tax Liability (DTL) = 80000 × 25% = 20000

      Warranty Temporary Difference (Deductible): Carrying Value > Tax Base by 60000.
      Deferred Tax Asset (DTA) = 60000 × 25% = 15000

      Net Deferred Tax Impact for Year: Net DTL increase of 5000 (20000 DTL − 15000 DTA).
