Hong Kong Company Tax and Annual Compliance in 2026 — What You Actually Owe, Every Year

Hong Kong's territorial tax principle gets most of the attention, but the two-tiered Profits Tax rate and a Companies Registry deadline measured in weeks, not months, are the details that actually decide whether a Hong Kong entity stays cheap to run or starts accumulating avoidable penalties.

What you owe on income

Hong Kong taxes profits arising in or derived from Hong Kong — the territorial principle — under a two-tiered Profits Tax structure: 8.25% on the first HK$2,000,000 of assessable profits, 16.5% on the remainder (the flat rate outside the two-tier election is 16.5%). One caveat: the lower tier applies to only one entity per group of "connected entities" under common control above 50% — it has to be nominated in the Profits Tax Return. And the territorial exemption for offshore-sourced profits isn't automatic; it requires proper analysis and a claim, not just an assumption.

What you owe every year, regardless

Annual Return (Form NAR1), filed with the Companies Registry within 42 days of the incorporation anniversary — a noticeably tighter window than most jurisdictions on this list. On-time filing costs HK$105; miss it and the fee escalates fast: HK$870 within 3 months late, HK$1,740 within 3–6 months, HK$2,610 within 6–9 months, HK$3,480 beyond 9 months.

Business Registration Certificate renewal, with the Inland Revenue Department, annually or every 3 years on the certificate's anniversary. A standard 1-year certificate (period 1 April 2026–31 March 2027) costs HK$2,200 plus a HK$150 levy — HK$2,350 total; a 3-year certificate runs HK$5,720 plus HK$450 levy.

Profits Tax Return (BIR51), filed with the IRD. Exact due dates vary by the company's accounting year-end and whether a tax representative uses the Block Extension Scheme — these shift slightly each year, so pull the current cycle's specific date from IRD's own annual filing notice rather than assuming last year's date repeats.

What happens if you're late

Missing the Annual Return isn't just a fee escalation — it's a criminal offence under s.662 of the Companies Ordinance. The company and every responsible officer can be prosecuted, facing a maximum fine of HK$50,000 per breach plus a daily default fine of HK$1,000 for continuing non-compliance. Late Profits Tax filings can trigger an estimated assessment, a compound penalty commonly around HK$10,000 for a first offence, additional tax under s.82A of up to three times the tax undercharged for serious cases, and potential prosecution.
