Am I a tax resident of Singapore?

Short answer: usually yes once you cross 183 daysSingapore Statutes Online, Income Tax Act 1947 (Attorney-General's Chambers)“includes a person who is physically present or who exercises an employment (other than as a director of a company) in Singapore for 183 days or more during the year preceding the 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 Singapore

The number that decides it: 183 daysSingapore Statutes Online, Income Tax Act 1947 (Attorney-General's Chambers)“includes a person who is physically present or who exercises an employment (other than as a director of a company) in Singapore for 183 days or more during the year preceding the year of assessment”View source · accessed 2026-10-24. Cross that in a year, and Singapore counts you as tax resident. The 183-day test is in the Income Tax Act and counts the calendar year before the year of assessment. The three-year and two-year rules are IRAS administrative concessions, not statute.

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 Singapore’sverified threshold, so you are working from a real count instead of a guess.

What residency actually changes

Stay a non-resident, and Singapore typically taxes only income sourced there.
