Singapore tax residency: the 183-day rule in practice
14 July 2026 · 4 min read
In short
A foreigner is generally treated as a Singapore tax resident for a calendar year if they stay or work in Singapore for 183 days or more in that year. Residents pay progressive rates (0–24%) with reliefs; non-residents pay a flat 15% on employment income or the progressive rate, whichever is higher, with no reliefs.
The 183-day rule
Singapore taxes by calendar year. A foreigner who stays or works in Singapore for at least 183 days in a calendar year is generally treated as tax resident for that year. Physical presence and employment days both count, and IRAS also applies concessions that can treat continuous stays spanning two or three years as resident throughout.
Why residency status matters
- Residents pay progressive rates from 0% up to 24% and can claim personal reliefs.
- Non-residents pay a flat 15% on employment income or the resident progressive rate, whichever produces more tax — and get no reliefs. Director's fees and most other income are taxed at 24%.
Counting days properly
If you split time between Singapore, the UK and elsewhere, the same travel history feeds several different tests: Singapore's 183 days per calendar year, the UK's 183 midnights per 6-April tax year, India's 182/120 days per 1-April financial year. One log, three different year boundaries — which is exactly the bookkeeping that goes wrong in spreadsheets.
How TaxDin helps
TaxDin stores one day-by-day location log and re-buckets it by UK tax year or calendar year instantly, with live badges for the Singapore 183-day and India thresholds and workday tracking for Singapore. Your accountant gets a clean Excel export instead of a shoebox of boarding passes.
