Welcome to Depreciation Allowances: Plant and Machinery!
Hello there! Welcome to one of the most practical and high-scoring chapters in the Profits Tax section of your HKICPA QP studies. If you have ever looked at a company’s financial statements and seen "Depreciation," you might have wondered how the taxman treats those numbers.
In short: The Inland Revenue Department (IRD) doesn't trust accounting depreciation because every company calculates it differently. Instead, they give us Depreciation Allowances (DA) based on a strict set of rules. Think of DA as the "Tax Version" of depreciation. By the end of these notes, you will know exactly how to calculate these allowances and help a business lower its taxable profits. Let's dive in!
1. What Counts as "Plant and Machinery" (P&M)?
Before we calculate anything, we need to know what qualifies. Not every "thing" a business buys is P&M.
The Basic Rule: To qualify for DA, the item must be capital expenditure used for the production of chargeable profits.
The "Setting" vs. "Apparatus" Test:
Don't worry if this sounds legalistic! Think of it this way:
- If the item is the apparatus (the tool) with which the business is carried out, it is P&M (e.g., a computer, a delivery van).
- If the item is just the setting (the place) where the business is carried out, it is usually NOT P&M (e.g., the walls of an office, a ceiling).
Example: A decorative lamp in a normal office might be "setting," but a specialized lighting system in a photographic studio is "plant."
Key Takeaway:
Only assets used in the business to help earn money qualify for DA. Buildings and land have their own separate rules (Industrial/Commercial Building Allowances).
2. The Three Pillars: IA, AA, and the Pool System
In Hong Kong, we don't track every single stapler or chair individually. We throw them into "Pools" based on how fast they wear out. There are three main components you need to master:
A. Initial Allowance (IA)
When a business buys a new piece of P&M, they get a "Welcome Gift" from the IRD.
The Rate: 60% of the cost.
When: In the year the money is spent (incurred).
Formula: \( \text{Cost} \times 60\% \)
B. Annual Allowance (AA)
This is the yearly "wear and tear" allowance. It is calculated on the Reducing Value of the pool.
The Rates: 10%, 20%, or 30% (depending on the type of asset).
Formula: \( \text{Reducing Value (after IA)} \times \text{AA Rate} \)
C. The Pooling System
Assets are grouped into three buckets based on their AA rate:
- 10% Pool: Things that last a long time (e.g., air conditioning systems, lifts).
- 20% Pool: Most furniture, fixtures, and general machinery.
- 30% Pool: Things that wear out fast (e.g., motor vehicles, computers, electronic equipment).
Did you know?
The IRD is quite generous! If you buy a computer for \$10,000, you get a 60% IA (\$6,000) immediately. Then you get a 30% AA on the remaining \$4,000. That’s a total tax deduction of \$7,200 in the very first year!
3. Step-by-Step: The Calculation Process
When you face a "Depreciation Allowance" question in the exam, follow these steps for each pool:
Step 1: Start with the Opening Written Down Value (WDV)
This is the value left over from the previous year.
Step 2: Add New Purchases (Additions)
For every new asset:
1. Calculate the IA: \( \text{Cost} \times 60\% \).
2. Add the Net Amount \( (\text{Cost} - \text{IA}) \) to the pool.
Step 3: Subtract Sales (Disposals)
If you sell an asset, subtract the sale proceeds from the pool.
Important: You cannot subtract more than the original cost of that asset.
Step 4: Calculate the AA
Multiply the remaining Pool Balance by the relevant rate (10%, 20%, or 30%).
Step 5: Find the Closing WDV
\( \text{Pool Balance} - \text{AA} = \text{Closing WDV} \)
Summary of Total DA:
The total deduction for the year is: Total IA + Total AA. This amount is deducted from the company’s taxable profit.
4. Special Cases: Balancing Charges and Allowances
Sometimes, the "Pool" system acts a bit weirdly when we sell things. Here are two terms you MUST know:
Balancing Charge (BC) - "The Tax Payback"
If you sell an asset for a lot of money and the sale proceeds are greater than the balance in the pool, you have a negative pool.
The IRD doesn't allow negative pools. This negative amount becomes a Balancing Charge, which is treated as taxable income.
Analogy: It’s like you claimed too much depreciation in the past, and now the IRD is taking some of that tax benefit back.
Balancing Allowance (BA) - "The Final Deduction"
A Balancing Allowance only happens when a business closes down (cessation). If there is still a value left in the pool after all assets are sold, that remaining value is given as a BA (a final deduction) to the taxpayer.
5. 100% Write-offs (The Fast Track)
To encourage businesses to upgrade, the government allows a 100% immediate deduction for certain assets. These do not go into the pools. They are deducted fully in Year 1.
1. Prescribed Fixed Assets: Computer hardware, software, and manufacturing machinery.
2. Environmental Protection Machinery: Low-emission vehicles, solar panels, etc.
3. Environmental Protection Installations: Specific green building features.
Common Mistake: Students often put "Computer Software" into the 30% pool. Don't do that! It’s a 100% write-off under Section 16G.
6. Hire Purchase (HP) – Don't get confused!
If a business buys a machine on Hire Purchase (installments), they don't own it fully until the last payment. However, for tax purposes:
- IA: Only given on the capital portion of the installments paid during the year.
- AA: Given on the full cash price of the asset (as long as it’s in use), even if not all installments are paid yet.
Think of it this way: The IRD lets you claim the "wear and tear" (AA) on the whole machine because you are using the whole machine, but they only give the "purchase gift" (IA) on the money you actually handed over this year.
7. Quick Review: Common Pitfalls to Avoid
1. Sales Proceeds: Always remember that sale proceeds deducted from a pool cannot exceed the original cost of that specific asset.
2. Date of Expenditure: IA is claimed when the "obligation to pay" arises. Usually, this is the invoice date.
3. Private Use: If a boss uses a company car 25% for weekend trips, you must reduce the DA by 25%. Only the business portion is deductible!
4. 100% Write-offs: Keep these separate from your 10%/20%/30% pool calculations.
Encouragement: DA calculations look like a big puzzle at first, but once you practice the "Pool" table format a few times, it becomes mechanical. You've got this!
