Hong Kong Renewable Energy Tax — Expert Advisory

Yes. Solar photovoltaic panels, inverters, mounting systems, and associated electrical infrastructure installed for use in a trade or business qualify as plant & machinery for capital allowance purposes. The 60% initial allowance applies in the year of installation, with 20-30% annual allowance on the reducing balance thereafter. Building-integrated solar that forms part of the building structure may qualify as a building improvement under s.16C renovation allowances instead.

Carbon credits are a relatively new asset class for HK tax purposes. If a company buys and sells carbon credits as a trading activity (regularly, with profit motive), the gains are likely assessable as trading profits under s.14 IRO. If carbon credits arise from a company's own qualifying projects and are sold as a one-off realisation, they may be capital in nature (no CGT in HK). Given the evolving IRD position, maintaining clear documentation of the purpose and nature of all carbon credit transactions is essential.

Yes, if the clean technology development meets the s.16B qualifying test — systematic investigation to advance scientific or technological knowledge, or application of existing knowledge in a new way. This can include: developing new battery chemistry, improving solar cell efficiency, creating novel green materials, or inventing new energy management systems. Routine engineering design, building compliance testing, and standard technology adaptation generally do not qualify.

Green bond issuance costs — legal fees, underwriting fees, rating agency fees, green certification costs, and listing fees — are generally capital expenditure related to raising financing, which is not directly deductible as revenue expenditure. However, the interest paid on green bonds is deductible as it relates to borrowings used in the business. Some issuance costs may be amortised over the bond term for accounting purposes; the tax treatment follows the accounting treatment if consistently applied.

The Hong Kong government's Feed-in-Tariff scheme pays solar system owners for electricity generated and fed back to the grid. FiT income received by a company operating a solar installation as a business is assessable as trading income subject to profits tax. For individuals, FiT income may be assessable under the property tax regime or as business income depending on the scale of operations. The electricity savings from self-consumed solar generation are not income but reduce operating costs.
