Am I a tax resident of Hong Kong?

Short answer: usually yes once you cross 180 daysInland Revenue Department (IRD), Certificate of Resident Status“Individual who stays in Hong Kong for more than 180 days during a year of assessment or for more than 300 days in two consecutive years of assessment one of which is the relevant year of assessment”View source · accessed 2026-10-24 in a year. But a day count is only the headline test — a home, family, or economic ties can pull you in sooner, and staying under it does not automatically keep you out.

The residency test in Hong Kong

The number that decides it: 180 daysInland Revenue Department (IRD), Certificate of Resident Status“Individual who stays in Hong Kong for more than 180 days during a year of assessment or for more than 300 days in two consecutive years of assessment one of which is the relevant year of assessment”View source · accessed 2026-10-24. Cross that in a year, and Hong Kong counts you as tax resident. More than 180 days in a year of assessment (or more than 300 days over two consecutive years) makes an individual a Hong Kong resident for treaty purposes and for electing personal assessment. It does not decide salaries tax, which depends on where the employment is exercised.

Residency test
Salaries tax does not depend on residence, so the residence tests only matter for treaty claims and for electing personal assessment. A person is resident if ordinarily resident in Hong Kong or present more than 180 days in a year of assessment or more than 300 days in two consecutive years. [source]PwC Worldwide Tax Summaries“However, where it is necessary to determine an individual's residence, such as for the purpose of a CDTA, individuals who (i) ordinarily reside in Hong Kong SAR or (ii) stay in Hong Kong SAR for more than 180 days during a year of assessment or for more than 300 days in two consecutive years of assessment are generally considered as Hong Kong tax residents.”View source · accessed 2026-10-24
Tax year period
1 April to 31 March (as of 2026)PwC Worldwide Tax Summaries“An assessment year (or tax year) begins on 1 April of a year and ends on 31 March of the following year.”View source · accessed 2026-10-24 — The Hong Kong year of assessment runs from 1 April to 31 March and is named by the two calendar years it spans, so 2026/27 covers 1 April 2026 to 31 March 2027. It is not the calendar year.

If you're close to the line

A day count only helps if the count is right. Travel that crosses midnight, short trips home, and which end of a stay counts as arrival or departure all change the total — and get miscounted constantly.

The free 183 Days residency tracker logs your actual travel and checks it against Hong Kong’sverified threshold, so you are working from a real count instead of a guess.

What residency actually changes

Once you are tax resident, Hong Kong generally taxes your worldwide income, topping out at 17%Inland Revenue Department (IRD), PAM 39(e) A guide to Salaries Tax (1), May 2026“Salaries Tax is chargeable on the smaller of your net chargeable income at progressive rates and your net total income at standard rate.”View source · accessed 2026-10-24. The top progressive rate is 17% on net chargeable income above HKD 200,000, but tax cannot exceed the standard rate computation of 15% on the first HKD 5 million of net income and 16% above that. For high earners the cap binds, so the real marginal rate falls to 15% and then 16% above HKD 5 million (crossover about HKD 2.13 million for a single person with only the basic allowance, own calculation). Stay a non-resident, and Hong Kong typically taxes only income sourced there.

Frequently asked questions

How many days can I spend in Hong Kong before becoming a tax resident?

180 days. More than 180 days in a year of assessment (or more than 300 days over two consecutive years) makes an individual a Hong Kong resident for treaty purposes and for electing personal assessment. It does not decide salaries tax, which depends on where the employment is exercised. Arrival and departure days are counted according to Hong Kong’s own rule, not a universal convention — check the source below for the exact method.

Can I become a tax resident of Hong Kong even under the day count?

Yes, in some cases. Hong Kong also has rules beyond the simple day count — see the detail below. A permanent home, family, or economic ties can trigger residency independent of days spent.

What does tax residency in Hong Kong actually cost me?

Hong Kong’s income tax tops out at 17%. The top progressive rate is 17% on net chargeable income above HKD 200,000, but tax cannot exceed the standard rate computation of 15% on the first HKD 5 million of net income and 16% above that. For high earners the cap binds, so the real marginal rate falls to 15% and then 16% above HKD 5 million (crossover about HKD 2.13 million for a single person with only the basic allowance, own calculation). Residency is what makes you liable for it in the first place — non-residents are typically taxed only on Hong Kong-source income, not worldwide income.

When to talk to an advisor

This page maps Hong Kong’s general residency test. It cannot weigh your treaty position, your specific ties, or the timing of a move. If meaningful money depends on the answer, have a qualified advisor in Hong Kong (and in your home country) review your situation before you act.
