⚠ Aviation Tax Requires Specialist Knowledge
Airline and aviation tax involves overlapping international agreements, complex capital allowance rules for aircraft, and unique salaries tax situations for aircrew. Generic tax advisors frequently miss key exemptions or create compliance exposures in this sector.
Common Challenges
Airline Income Exemption
Under s.23C IRO and bilateral agreements, income of certain non-resident airlines from international carriage may be exempt from HK profits tax. Qualification depends on reciprocity.
⚠ Risk: Missing exemption → double taxation on airline income
Aircrew Salaries Tax
Pilots and cabin crew on international routes have complex salaries tax obligations. Time-apportionment based on flight hours in HK airspace is the standard approach.
⚠ Risk: Full HK salaries tax on all aircrew income
Aircraft Capital Allowances
Aircraft are high-value assets. Capital allowances on aircraft acquisition, modification, and engine overhaul are significant but have specific rules.
⚠ Risk: Under-claiming → significant deduction leakage
MRO & Ground Services
Maintenance, repair, and overhaul services and ground handling income earned in HK are fully taxable. Separation from exempt airline income is critical.
⚠ Risk: Incorrect pooling → loss of exemption for exempt income

Frequently Asked Questions
Are foreign airlines exempt from Hong Kong profits tax?
Under s.23C of the IRO, profits of a non-resident from the operation of ships or aircraft are exempt from profits tax, subject to reciprocity. Many airlines benefit from bilateral air services agreements (ASAs) that provide mutual exemptions. The key test is whether the airline's home jurisdiction provides equivalent exemption to HK airlines. Airlines should confirm their eligibility on a route-by-route basis.
How is pilots' salaries tax calculated in Hong Kong?
Pilots resident in Hong Kong are subject to salaries tax on their worldwide income from employment. However, they can claim time-apportionment relief for periods spent outside HK on international duties. The calculation is based on the ratio of HK flight time / HK ground days to total days in the assessment year. Each airline may have a different agreed methodology with the IRD.
What capital allowances apply to commercial aircraft?
Commercial aircraft are classified as plant & machinery for capital allowance purposes. They are typically pooled in a 30% declining balance pool, attracting 60% initial allowance in the year of acquisition and 30% annual allowance thereafter. Engine overhaul costs may be capitalised and added to the pool or treated as revenue expenditure depending on the nature and accounting treatment.
Is aircraft leasing income taxable in Hong Kong?
Yes. Aircraft leasing is a taxable activity in Hong Kong, subject to profits tax at 16.5% for corporations. Hong Kong has positioned itself as an aircraft leasing hub with specific tax incentives: aircraft lessors can apply for a concessionary 8.25% tax rate (half the standard rate) under the Aircraft Leasing Tax Concession introduced in 2017.
How should in-flight sales revenue be treated for tax?
In-flight duty-free sales and in-flight catering revenue earned by an airline during flights through HK airspace is generally apportioned based on the portion of the journey in HK airspace versus international airspace. For most international flights, the HK-airspace portion is small. Consult with an aviation tax specialist to establish an IRD-approved apportionment methodology.
