The headline personal income tax (PIT) rate is 24.

An individual is a Singapore tax resident for a Year of Assessment if they are a citizen or permanent resident who normally resides in Singapore, or a foreigner who stayed or worked in Singapore for 183 days or more in the preceding calendar year (or across a continuous period straddling two calendar years, provided the total stay is at least 183 days - an administrative concession that also extends residency treatment to both years involved). Foreigners holding a work pass valid for at least a year are also treated as resident, subject to review at tax clearance. Days need not be consecutive. Residents are taxed on Singapore-source income and remitted foreign income at progressive rates; with limited exceptions, Singapore does not tax foreign-source income at all, even where deposited locally. Non-residents face a flat 15% rate or the resident progressive rate, whichever is higher.
Singapore has no Controlled Foreign Company regime. Undistributed profits of a foreign subsidiary controlled by a Singapore resident are not attributed to that resident regardless of where or how lightly the subsidiary is taxed.
Singapore has no formal thin capitalization or fixed debt-to-equity rule. Interest deductions can still be restricted or denied under Singapore's general anti-avoidance provisions and transfer pricing rules where financing arrangements are not on arm's-length terms.
Singapore has signed 98 comprehensive double tax agreements plus 8 limited DTAs (covering only shipping and aviation income) and 2 tax information exchange arrangements. Notably, Singapore has no comprehensive income tax treaty with the United States - only a limited 1985 shipping and aviation agreement and a Model 1 FATCA intergovernmental agreement, neither of which reduces US income tax for individual Americans. To claim treaty benefits, both individuals and companies must obtain a Certificate of Residence from IRAS; since 2025, foreign-owned holding companies claiming treaty benefits must demonstrate real economic substance in Singapore (genuine executives based there, not just administrative support).
