M&N Secretarial: A complete list of tax deductible expenses of Hong Kong companies

Every year during the tax season, many bosses have a headache when it comes to filing tax returns: Which of the many expenses can be deducted legally to help the company save more money?

Many Hong Kong SME owners and financial controllers face the same confusion: which of the various types of expenses incurred in the company's daily operation can be legitimately used as tax deductions to reduce assessable profits? With clear tax deduction guidelines, you can not only minimize your tax burden, but also standardize your company's financial management. Hong Kong's tax system is “principle-based” rather than “rule-based”, which is different from many other jurisdictions. Instead of an exhaustive list of deductible items, the law establishes the core principle that any expenditure incurred for the purpose of producing taxable profits that is not of a capital or personal nature is generally deductible. In short, the key to determining whether money is “wholly, exclusively and necessarily” used to generate taxable profits.

Core Principles of Tax Deduction

According to section 16 of the Hong Kong Inland Revenue Ordinance, the most basic principle of tax deduction can be summarized in one sentence:The expenditure must have been incurred for the purpose of producing taxable profits of your company.

In other words, you must be able to prove to the Inland Revenue Department that the expenditure is directly and necessarily related to the income earned from your business.

The “principle-based” system is flexible, but at the same time requires enterprises to keep clear and complete supporting documents. When conducting audits, the IRD adheres to the principle of “principle-based".“No record, no tax deduction” stand.

According to the law, all documents and business records related to tax filing must be properly kept at least7 years
