Hong Kong Business Expense Deductions: A Guide

Every tax season, business owners face the same question: which company expenses can be deducted lawfully to reduce tax?

Hong Kong SME owners and finance managers often wonder which day-to-day operating expenses can reduce assessable profits. Clear deduction guidance helps reduce tax lawfully and improve financial management. Hong Kong uses a principles-based rather than rules-based tax system. Instead of an exhaustive list, the law establishes a core principle: expenses incurred in producing assessable profits are generally deductible unless capital or private in nature. The question is whether the money was wholly, exclusively and necessarily spent to earn assessable profits.

The Core Deduction Principle

The basic principle under section 16 of the Inland Revenue Ordinance is: The expense must be incurred in producing your company’s assessable profits.

You must be able to demonstrate a direct and necessary connection between the expense and earning business income.

This flexible approach requires clear, complete supporting documents. In a review, the department takes a no-records, no-deduction approach.

Tax-related documents and business records must legally be retained for at least 7 years.

Main Deductible Expenses

The following categories summarise common deductible business expenses:

Expense Category	Examples and Key Points
Employee expenses	Salaries, bonuses and allowances; mandatory MPF contributions, subject to specified limits; and statutory severance or long service payments.
Premises and operating costs	Office, warehouse and shop rent; related water, electricity, business internet and telephone charges; building management fees.
Direct business costs	Purchases, direct costs of providing services, raw materials and inventory.
Marketing and entertainment	Advertising and marketing; client entertainment for business purposes, supported by detailed records; and business travel, including flights and hotels.
Professional fees	Audit, accounting and bookkeeping fees; legal fees related to operations, such as debt recovery.
Finance and insurance	Interest on borrowings used to produce profits; business insurance, such as employee compensation and fire cover; bank charges.
Repairs and maintenance	Costs of repairing and maintaining machinery, equipment and business premises. Improvements or upgrades are capital expenditure and treated differently.
Special deductions	Approved charitable donations of at least $100, capped at 35% of assessable profits; commercial building refurbishment capital expenditure, deductible in equal instalments over 5 years.
Depreciation allowances	Expenditure on computer hardware, software, environmental installations and other specified assets may be deducted in full in the purchase year. Other equipment, such as furniture and machinery, qualifies for an initial allowance of 60% of cost and annual depreciation allowances.

Common Non-Deductible Expense Pitfalls

As well as knowing what qualifies, avoid these common non-deductible items and expenses requiring special treatment:

Private or domestic expenditure: Private spending by owners, partners or family members must not be included in company accounts. For example, remuneration or interest paid to a sole proprietor or spouse is not deductible.
Capital expenditure: purchasing or improving long-term assets, such as property, vehicles and major equipment, is generally not immediately deductible in full. Relief is spread through depreciation allowances over the years.
Company tax and fines: the profits tax payment itself is not deductible. Fines or penalties for unlawful conduct are also generally non-deductible.
Non-business expenditure: expenses without a direct connection to assessable profits, such as purely internal staff welfare events without records of a commercial purpose, are difficult to deduct.

Frequently Asked Questions

How can I claim entertainment expenses without problems?

Entertainment is a common area for tax checks. A receipt alone is insufficient. Keep internal records of the date, client company and names, and the specific business discussed to establish commercial necessity.

Are pre-opening costs deductible?

No. Setup expenses incurred before business operations begin, such as incorporation fees, are generally capital in nature and not directly deductible.

Must the company file a return if it makes a loss?

Yes, it must file on time. Business losses can be carried forward indefinitely to offset future profits. Properly recording losses prepares for future tax savings.

How are reinstatement costs at the end of a lease treated?

From the 2024/25 year of assessment, costs of restoring an office to its original condition to meet lease terms are deductible.

Are R&D expenses eligible for concessions?

Yes. Qualifying R&D expenses receive enhanced deductions. The first $2,000,000 of qualifying Type B expenditure receives a 300% enhanced deduction, with 200% for subsequent expenditure.
