Capital Allowance Strategy in Hong Kong | Maximizing IA, AA, and Section 16G

Hong Kong capital allowance strategy becomes important the moment a business starts spending on equipment, fit-out, computers, software, machinery, or business premises. Many SMEs record these payments as ordinary expenses and move on. 

That can create trouble at tax time because capital spending is not handled like rent or staff cost. The right claim depends on the asset type, business use, purchase timing, disposal value, and the section of the Inland Revenue Ordinance that applies.

Why Capital Allowances Need Planning?

A founder may buy laptops, office furniture, warehouse equipment, factory machinery, or a van during the year. The accounting file may show one simple payment. The tax file needs more detail.

Hong Kong does not normally allow a straight revenue deduction for capital expenditure. Instead, relief is usually given through depreciation allowances, building allowances, or specific deduction rules. IRD’s Profits Tax guidance confirms that plant and machinery can receive an initial allowance and annual allowances, while certain buildings and structures follow building allowance rules.

That is why the invoice description matters. “Office setup” is too broad. The accountant needs to know what was bought, when it was first used, where it is used, and if it falls into a faster deduction route.

Initial Allowance Annual Allowance Hong Kong Rates

Initial allowance annual allowance Hong Kong rates apply mainly to plant and machinery. IRD states that plant and machinery can receive an initial allowance of 60% on cost. After that, annual allowance is given at 10%, 20%, or 30% on the reducing value of the asset. Items with the same annual allowance rate are grouped into the same pool. 

For example, a company buying HK$100,000 of qualifying equipment may claim 60% initial allowance in the purchase year. The remaining value then enters the right pool for annual allowance. This is helpful for cash flow because a large part of the deduction can come early.

But this does not mean every fixed asset gets the same treatment. A desktop computer, a production machine, a delivery vehicle, and office furniture may follow different tax paths.

Main Capital Allowance Routes At A Glance

Section 16G Plant Machinery 100% Deduction

Section 16G plant machinery 100% deduction is one of the most useful areas for SMEs because it can give a faster deduction than normal depreciation allowances.

IRD’s 2025-26 brief guide says immediate writing off is allowed for capital expenditure on plant and machinery specifically related to manufacturing, and on computer hardware and software. 

This can help a business that buys servers, computers, accounting software, design software, or manufacturing machinery. But the claim still needs support. The company should keep the invoice, purchase date, payment proof, business-use note, and asset register. If software is partly personal, partly business, or bundled with support services, the accountant should split the cost properly.

A common mistake is posting everything under “IT expense.” That may hide the difference between software subscription fees, computer hardware, licence purchases, maintenance, and capital software.

Industrial Commercial Building Allowance HK

Industrial commercial building allowance HK rules need more care because buildings do not follow the same route as laptops or machinery.

IRD’s guidance says a commercial building or structure can qualify for an annual commercial building allowance of 4% of capital expenditure on construction. When the asset is sold, a balancing allowance or balancing charge may be made based on the difference between disposal price and written-down value. 

For commercial buildings, IRD also clarified in 2026 that there is no 20% initial allowance. The annual allowance is generally 4%, while industrial building allowances are treated differently because industrial buildings face higher wear and tear after occupation. 

This matters for hotels, warehouses, offices, showrooms, clinics, and mixed-use premises. A company should not assume a building cost gets fast relief only because the business uses it heavily.

Capital Expenditure Tax Planning Hong Kong

Capital expenditure tax planning Hong Kong should start before large purchases are made. The tax result can change depending on asset description, timing, business use, and supporting documents.

For example, a company may spend HK$400,000 on a new office. 

• Part of it may be furniture. 
• Part may be computer equipment. 
• Part may be renovation. 
• Part may be electrical work. 

If the full amount is booked as one “office setup” cost, the tax claim becomes harder. If the invoice is split clearly, the accountant can assess each part correctly.

Timing also matters. If a business buys machinery before operations begin, IRD’s practice note says expenditure for assets of a new trade about to begin may be treated as incurred on the day the new trade starts. That can affect the year in which allowances are claimed.

A clean asset register is the easiest starting point.
