Tax Planning for Specific Managerial Decisions

Understand Tax Planning for Specific Managerial Decisions

Key rules to remember

WDV of a block of assets (section 41(1)(c))

WDV = [(A – D) + B – C] – E

A = opening WDV; B = cost of assets acquired in the year; C = sale money plus scrap, not more than (A – D) + B; D = depreciation allowed on the preceding year; E applies only to slump sale.

WDV of an asset acquired in the year

WDV = actual cost to the assessee

Section 41(1)(a). For earlier years it is cost less depreciation actually allowed (section 41(1)(b)).

Post-tax cost of an expense

Net cost = Expense × (1 – tax rate)

Use for deductible items such as lease rent, repair cost and purchase cost of goods.

Tax saved on depreciation

Tax shield = Depreciation × tax rate

Discount each year's shield if a discount rate is given.

Net present value of cost

PV = Σ [Post-tax cash flow ÷ (1 + r)^t]

Choose the option with the lower present value of cost, or the higher present value of benefit.

Advance tax estimate (section 406)

Advance tax is paid on the current income estimated by the assessee

You may raise or lower the remaining instalments to match the revised estimate.

How to solve Tax Planning for Specific Managerial Decisions questions

1. 1Name the decision and the options being compared. Write the tax rate and the discount rate if given.
2. 2List all cash flows for each option: cost, revenue, rent, repair, scrap, and any one-time outlay.
3. 3Mark each item as deductible, capital, or non-deductible. Capital items give depreciation, not a direct deduction.
4. 4Compute the tax effect: tax saved on expenses and depreciation, and tax payable on income or gain.
5. 5Find the net cash flow after tax for each option for each year.
6. 6Discount the flows if a rate is given. If no rate is given, add them undiscounted and say so.
7. 7Compare the totals and state the recommended option in one line.
8. 8Add a short note on qualitative or compliance points, such as advance tax or the effect on the block of assets.

Quickest way: Post-tax comparison table

Common mistakes in Tax Planning for Specific Managerial Decisions

• Comparing pre-tax costs only.

  Students copy the management accounting method and forget tax.

  Fix: Always convert every deductible cost to a post-tax figure before you compare.

• Deducting the full purchase price of an asset in year one.

  The purchase looks like an expense.

  Fix: Treat it as capital. Add it to the block and claim depreciation only as the Act allows. Only the depreciation gives a tax shield.

• Ignoring the sale of an old asset in a replace decision.

  Students focus on the new asset.

  Fix: Deduct the sale money from the block (item C in section 41(1)(c)) and compute the effect on later depreciation.

• Treating lease rent and loan interest together with depreciation in the buy option incorrectly.

  Own-or-lease questions mix several items.

  Fix: For buying, include the price, depreciation shield and any interest deduction. For leasing, include only post-tax rent. Do not count the same item twice.

• Forgetting fixed costs that continue after a shutdown.

  Students treat all costs as saved.

  Fix: List avoidable and unavoidable costs separately. Only avoidable costs count as savings from shutting down.

• Using the wrong tax rate or applying tax to a loss without comment.

  Rules on set-off and carry forward are overlooked.

  Fix: Use the rate stated in the question. If the unit has a loss, state your assumption on whether it is set off against other income.
