Income taxes

Welcome to the World of Income Taxes (HKAS 12)!

Hello there! Don't let the word "Tax" intimidate you. While tax law can be a maze, the accounting for it under HKAS 12 Income Taxes follows a very logical set of steps. In this chapter, we are bridging the gap between how we record transactions for our shareholders (Accounting Profit) and how the Inland Revenue Department (IRD) wants us to calculate tax (Taxable Profit). By the end of these notes, you'll see that it's all about managing timing differences!

1. The Big Picture: Current Tax vs. Deferred Tax

In Financial Reporting, we deal with two main types of income tax:

1. Current Tax: This is the amount of income tax you actually owe the government for the current period. It is based on your taxable profit, not your accounting profit.
2. Deferred Tax: This is the "future" tax consequence. It represents taxes that will be paid (or saved) in future periods because of transactions happening today.

Analogy: Imagine you buy a coffee on credit. Current Tax is the cash you pay for a coffee you drink today. Deferred Tax is the IOY you write to the barista, promising to pay for it next week. Even though no cash moves today, you still have an obligation to pay later!

2. Calculating Current Tax

Current tax is relatively straightforward. You take the Taxable Profit (calculated according to tax law) and multiply it by the Tax Rate.

\( \text{Current Tax Expense} = \text{Taxable Profit} \times \text{Enacted Tax Rate} \)

Important Point: If you overestimated or underestimated your tax in the previous year, you must adjust for that "Under/Over-provision" in the current year's tax expense.

Quick Review: The Current Tax Formula

Current Tax Expense for the year = Provision for the current year +/- Under/Over-provision from previous years.

3. The Heart of the Matter: Deferred Tax

Deferred tax exists because accounting rules (HKFRS) and tax rules (Inland Revenue Ordinance) treat income and expenses at different times. These are called Temporary Differences.

To find these differences, we compare two values for every asset and liability:
1. Carrying Amount (CA): The value on your Balance Sheet (SFP).
2. Tax Base (TB): The value the taxman assigns to that asset/liability.

A. What is a Tax Base?

Think of the Tax Base as the "accounting value" if the tax authorities were the ones keeping your books.

- For an Asset: The amount that will be deductible for tax purposes against any taxable economic benefits that will flow to the entity when it recovers the carrying amount of the asset.
- For a Liability: Its carrying amount, minus any amount that will be deductible for tax purposes in respect of that liability in future periods.

B. Taxable vs. Deductible Temporary Differences

Don't worry if this seems tricky at first! Use this simple logic for Assets:

- If CA > TB: You have a Taxable Temporary Difference. This leads to a Deferred Tax Liability (DTL). (Think: "I have more value on my books than the taxman knows about, so I'll have to pay more tax later.")
- If CA < TB: You have a Deductible Temporary Difference. This leads to a Deferred Tax Asset (DTA). (Think: "The taxman gives me more 'credit' than I have on my books, so I'll save tax later.")

Note: For Liabilities, the logic is simply reversed!

Memory Trick: The "Asset-DTL" Rule

Asset Greater (CA > TB) = Liability (DTL). Just remember "A-G-L"!

4. Recognition and Measurement

Once you identify the temporary difference, how do you value it?

\( \text{Deferred Tax} = \text{Temporary Difference} \times \text{Tax Rate} \)

Key Rules for Measurement:
1. Use the tax rates that are expected to apply when the asset is realized or the liability is settled (the enacted or substantively enacted rate).
2. Do NOT discount deferred tax assets or liabilities. Even if the tax will be paid in 10 years, we record the full amount today.

The Prudence Principle for Deferred Tax Assets (DTA)

We are usually happy to record a Liability (DTL) because it's a future debt. However, for a Deferred Tax Asset (DTA), we must be careful. We only recognize a DTA if it is probable that there will be enough taxable profit in the future to use that tax saving against. If we don't expect to make money in the future, that "tax saving" is useless!

5. Common Scenarios in HKICPA Exams

Here are the most common "Accounting vs. Tax" conflicts you will see:

1. Depreciation:
- Accounting uses "Depreciation Expense".
- Tax uses "Tax Depreciation" (often called Capital Allowances).
- If Tax Depreciation > Accounting Depreciation, the CA will be higher than the TB, creating a DTL.

2. Accrued Expenses:
- You record an expense in the accounts when it's incurred (e.g., a provision for a lawsuit).
- The taxman often only allows the deduction when the cash is actually paid.
- This creates a DTA.

3. Revaluation of Assets:
- If you revalue a building upwards, the CA increases.
- The Tax Base usually stays the same (historical cost).
- This CA > TB creates a DTL. Crucially, the "tax expense" for this is recorded in Other Comprehensive Income (OCI), not the Profit or Loss!

6. Presentation and Disclosure

How do we show this in the financial statements?

- In the Statement of Profit or Loss: Tax expense is the sum of Current Tax and the change in Deferred Tax.
- In the Statement of Financial Position: Deferred Tax Assets and Liabilities are always classified as Non-Current, no matter when they will reverse.
- Offsetting: You can only offset a DTA against a DTL if they relate to the same tax authority and you have a legal right to settle them on a net basis.

7. Summary and Key Takeaways

Did you know? HKAS 12 uses the "Balance Sheet Liability Method." This means we focus on the differences between the values of assets and liabilities, rather than just the differences in income and expenses.

Quick Summary:
1. Current Tax = Pay now (based on tax rules).
2. Deferred Tax = Pay/save later (based on CA vs TB).
3. CA > TB for an Asset = DTL (Future Tax Bill).
4. CA < TB for an Asset = DTA (Future Tax Saving).
5. Unused Tax Losses: These can create a DTA, but only if you are sure you'll make a profit soon!
6. Classification: Always non-current on the SFP.

Common Mistake to Avoid: Don't forget that tax rates can change! If the government announces a new tax rate for next year, you must use that new rate to calculate your deferred tax, as that's the rate that will apply when the difference actually reverses.

Keep practicing those CA vs. TB comparisons—they are the key to mastering this chapter! You've got this!
