Startup & I&T Tax Planning

Hong Kong offers some of the world's most generous tax incentives for innovation-driven companies — including 300% R&D deductions, a 5% patent box rate, and government grants that can be structured tax-efficiently. Most startups leave tens of thousands in unclaimed reliefs on the table every year.

⚠️

⚠ Government Grants Are NOT Automatically Tax-Free

Government grants — including BUD Fund, TVP, and certain InnoHK and HKSTPC grants — are not automatically exempt from profits tax. Revenue grants covering operating costs are fully taxable. Capital grants for equipment may qualify as capital receipts. We have seen startups receive HK$500,000 in grants and pay no attention to the tax consequence — then face unexpected assessments with penalties for incorrect returns.

Desafíos comunes

¿Se enfrenta a estos problemas fiscales?

Failing to Claim R&D Enhanced Deduction (s.16B)

Section 16B provides a 300% deduction on the first HK$2M of qualifying in-house R&D expenditure and 200% above. A HK$1.2M R&D spend correctly documented can generate HK$3.6M of deductions — saving HK$594,000 at 16.5%.

⚠ Risk: Hundreds of thousands in unclaimed R&D deductions

ESOP Mismanagement — Wrong Tax Event

ESOP taxation is complex: the taxable event is at exercise (not grant), employers must file IR56B returns for all option gains. Failure carries penalties, withholding obligations, and consequences for subsequent fundraising rounds.

⚠ Risk: Penalties up to HK$1.4M and deal delays

Treating All Grants as Non-Taxable

Revenue grants covering operating costs are fully taxable. Many startups receive HK$500K-2M in grants and file incorrect returns treating the entire amount as non-taxable, creating liability that surfaces during due diligence.

⚠ Risk: Unexpected tax assessments at worst possible time

Ignoring the Patent Box (5% Rate)

Hong Kong's patent box regime taxes qualifying IP income at just 5% — compared to 16.5%. For a SaaS startup with substantial licensed-software income, the differential is 11.5 percentage points of that income every year.

⚠ Risk: 11.5% unnecessary tax on qualifying IP income

Preguntas frecuentes

Preguntas frecuentes

Respuestas rápidas a sus preguntas

Section 16B provides 300% on the first HK$2M of qualifying in-house R&D expenditure and 200% above. s.16C covers 300% for payments to approved research institutes. Qualifying activities include software algorithm development, new product development, and platform architecture. Non-qualifying activities include maintenance, bug fixing, and routine customer support tooling. Contemporaneous project logs and time tracking are required.

The taxable event is generally the date of exercise — not grant. The chargeable amount is open market value at exercise minus the exercise price. Employers must file IR56B returns notifying IRD of all option gains. For employees who worked partly outside HK during the vesting period, only the HK-sourced proportion is chargeable. Failure to file carries penalties.

Taxability depends on the grant's character — capital or revenue. Grants subsidising capital assets reduce the cost base but are not directly taxable. Grants subsidising revenue expenses (salary costs, marketing, operations) are treated as taxable business income in the year of receipt. BUD Fund grants are typically revenue (taxable); TVP grants may be capital or revenue depending on the technology acquired.

The patent box reduces profits tax on qualifying IP income to approximately 5%, compared to 16.5%. Qualifying income includes royalties, licensing fees, and software income. Qualifying IP types include patents, software copyrights, and plant variety rights. The regime follows the OECD nexus approach — the qualifying proportion depends on the ratio of qualifying R&D expenditure to total R&D expenditure.

Hong Kong has no capital gains tax, so share disposals are generally not subject to tax if the sale represents a capital transaction. For founders who built a company over many years, the sale is almost invariably capital. For asset sales, the treatment is more complex — assets sold at a profit may generate taxable gains depending on depreciation allowances claimed. We provide pre-exit structuring to maximise capital treatment.
