Hong Kong Engineering & Architecture Tax — Expert Advisory

Engineering and architectural fees are sourced where the professional services are performed. Fees for design, analysis, and review work performed in Hong Kong are HK-source income. Fees for site supervision, local design, and on-site engineering work performed in overseas locations are offshore-source income and not subject to HK profits tax. The proportion depends on where the actual professional work was carried out — time sheets and project records are important evidence.

Yes. Professional indemnity insurance premiums are a deductible business expense for engineering and architectural practices. The insurance must be for professional liability directly arising from the practice's professional activities. Premiums paid to international PI insurers for global coverage are also deductible to the extent they relate to the HK practice's professional activities.

Annual membership fees and subscriptions to professional bodies directly related to the engineer's or architect's practice are deductible. This includes HKIE (Hong Kong Institution of Engineers), HKIA (Hong Kong Institute of Architects), HKIS (Hong Kong Institute of Surveyors), and overseas equivalents (ICE, IStructE, RIBA) that are maintained for professional practice purposes. General memberships without direct professional relevance are not deductible.

Work-in-progress represents the value of professional services rendered but not yet billed. In accounting terms, WIP is recognised as revenue based on the stage of completion. For tax purposes, the IRD generally follows the accounting treatment if it is consistently applied and provides a true and fair view. Unbilled work at year-end should be assessed at recoverable value — if there is doubt about recoverability, a provision may be appropriate.

Annual software subscription fees (e.g., Autodesk subscription, Revit, BIM 360) are typically deductible as operating expenses in the year they are paid. Perpetual software licences are capital expenditure qualifying for plant & machinery allowances. Hardware (workstations, plotters, survey instruments) is plant & machinery. Cloud computing costs for engineering simulation and analysis are operating expenditure deductible as incurred.
