Civil Aviation Department
This head (Head 28) has a 2026-27 estimate of HK$1,468.8 million p.1 (official document, opens in new tab). That is HK$13.8 million (0.9%) more than the 2025-26 revised estimate of HK$1,455.0 million p.1 (official document, opens in new tab) (our calculation).
The original 2025-26 estimate was HK$1,475.8 million p.1 (official document, opens in new tab), revised during the year to HK$1,455.0 million. Against the original estimate, 2026-27 is HK$6.9 million (0.5%) less (our calculation).
A household on the median income pays about HK$1,120 in salaries tax for 2026/27; about HK$2 of that would go to this department. A household on the median income earns HK$30,000 a month p.17 (official document, opens in new tab). If one married person earns all of it, salaries tax under the 2026/27 rules is about HK$1,120 (our calculation, after MPF and the married person's allowance p.107 (official document, opens in new tab), at progressive rates p.1 (official document, opens in new tab)). (our calculation: HK$1,120 × this head's estimate p.1 (official document, opens in new tab) ÷ total government expenditure of HK$843.4 billion p.12 (official document, opens in new tab). Tax is not earmarked; this splits it in proportion.)
