Welcome to the World of Building Allowances!

Hello there! Today, we are diving into a crucial part of the Profits Tax syllabus: Depreciation Allowances for Industrial and Commercial Buildings. In the world of accounting, we call it "depreciation," but in the Hong Kong tax world, the Inland Revenue Department (IRD) uses the term "Allowances."

Why do we need this? Well, the IRD generally doesn't allow you to deduct capital expenses (like buying a factory) directly from your profits. Instead, they give you these "allowances" over several years to recognize that buildings wear out over time. Don't worry if this seems a bit technical—think of it as a "tax discount" the government gives you for investing in the physical space where your business grows!

1. The Golden Rule: Land vs. Buildings

Before we look at the math, remember this one thing: Land never depreciates for tax purposes. When a company buys a property, the price usually includes the land and the building. We only calculate allowances on the cost of construction or the purchase price of the building itself. Always exclude the land cost!

2. Industrial Building Allowance (IBA)

An Industrial Building is specifically used for "qualifying trades." Think of places where things are actually made or stored on a large scale.

What counts as an Industrial Building?

To qualify for IBA, the building must be used for trades such as:
Manufacturing (making goods)
Transport, dock, or water undertakings
Storage of goods arriving in Hong Kong
Farming
Working of mines or wells

The "10% Rule" for Offices

Often, a factory has a small office inside it. Does the whole building get the Industrial Allowance?
• If the cost of the "non-qualifying" part (like an office or showroom) is 10% or less of the total cost, the whole building qualifies for IBA.
• If it is more than 10%, you must split the costs. The office part gets the Commercial Building Allowance (CBA), and the factory part gets the Industrial Building Allowance (IBA).

How to Calculate IBA

There are two types of allowances for industrial buildings:
1. Initial Allowance (IA): 20% of the capital expenditure. You get this only in the year you spend the money.
2. Annual Allowance (AA): 4% of the capital expenditure. You get this every year as long as you are using the building at the end of the basis period.

Quick Example:
Alpha Ltd spends \$1,000,000 (excluding land) to build a factory.
\n• Year 1 IA: \( \$1,000,000 \times 20\% = \$200,000 \)
\n• Year 1 AA: \( \$1,000,000 \times 4\% = \$40,000 \)
\n• Total Allowance in Year 1: \$240,000

Key Takeaway:

IBA = 20% IA + 4% AA. It’s the most generous allowance because the government wants to encourage industrial production!

3. Commercial Building Allowance (CBA)

If a building is used for business but doesn't qualify as an industrial building (like a retail shop, a standard office block, or a hotel), it falls under Commercial Building Allowance.

How to Calculate CBA

CBA is simpler than IBA because there is no Initial Allowance. You only get the Annual Allowance.
Annual Allowance (AA): 4% of the capital expenditure.

Wait! Did you know? Before 1998/99, the rate was only 2%. It was increased to 4% to help businesses. So, for your exam, just remember the 4% rule for both IBA and CBA annual allowances.

Key Takeaway:

CBA = 4% AA only. No "bonus" 20% at the start!

4. What Happens When We Sell? (Balancing Adjustments)

When you sell a building, the IRD does a "final check" to see if the total allowances they gave you match the actual wear and tear (loss in value).

The Concept of "Residue of Expenditure" (ROE)

ROE is basically the "Tax Book Value." It is:
Original Cost - All Allowances already granted = ROE

The Balancing Act

Compare the Sale Price (excluding land) with the ROE:
If Sale Price > ROE: You "made a profit" in the eyes of the IRD. This is a Balancing Charge (BC). You have to pay tax on this (it's added to your taxable income).
If Sale Price < ROE: You "suffered a loss." This is a Balancing Allowance (BA). You get an extra deduction!

Important Limitation on Balancing Charge:
A Balancing Charge can never be more than the total allowances you actually received in the past. The IRD only wants to take back the "excess" tax breaks they gave you; they aren't taxing the capital gain on the building's value increase here.

5. Common Pitfalls and Tips

1. Repairs vs. Improvements:
If you paint the walls, that's a "Repair" (deductible immediately as an expense). If you build an extra floor, that's "Capital Expenditure" (you must claim Building Allowances over many years). Don't mix them up!

2. The "Relevant Interest":
Only the person who holds the "relevant interest" (the person who spent the money on the building) can claim the allowance. If you lease a building, you usually can't claim CBA on the building itself, but you can claim it on the leasehold improvements (renovations) you paid for.

3. Timing:
You must be using the building at the end of your basis period to claim the Annual Allowance. If you sell it halfway through the year, you don't get the AA for that year; instead, you calculate the Balancing Adjustment.

6. Summary Table for Quick Review

Industrial Building (IBA)
Usage: Factories, Mills, Storage of goods.
Initial Allowance: 20%
Annual Allowance: 4%
10% Rule: Applies to offices within.

Commercial Building (CBA)
Usage: Shops, Offices, Banks, Hotels.
Initial Allowance: None (0%)
Annual Allowance: 4%
10% Rule: Not applicable.

Final Encouragement:

Building allowances can feel like a lot of numbers, but just remember the 4%. Almost everything moves at 4% per year in this chapter! Practice a few "Balancing Adjustment" calculations, and you'll be a pro in no time. You've got this!
