What is personal income tax for expats?
Singapore personal income tax for expatriates is governed by the Income Tax Act 1947. Tax residents are taxed on a progressive schedule from 0% to 24% on Singapore-sourced income, with personal reliefs available. Non-residents are taxed on Singapore-sourced employment income at 15% flat or the resident rate, whichever is higher, and on directors’ fees and other non-employment income at 24% flat.
Who personal income tax for expats is for
All foreign nationals working or earning income in Singapore — Employment Pass holders, S Pass holders, work-permit holders, dependent pass holders, and short-term assignees.

Step-by-step process
- Determine residency status under the 183-day rule — section 2 of the Income Tax Act 1947.
- Collect Form IR8A from the employer (issued by 1 March).
- Identify all Singapore-sourced income: employment, directors' fees, rental, dividends, royalties.
- Compute available reliefs — earned income, spouse, qualifying child, NSman, course fees, parent, life insurance, CPF top-up (citizens/PRs).
- Prepare Form B1 (resident) or Form M (non-resident) — IRAS portal auto-includes employer-filed data where AIS is in place.
- Submit by 15 April (paper) or 18 April (electronic); pay any tax due within 30 days of the Notice of Assessment.
- Plan for the next year — quarterly check-ins help avoid surprises at year-end.

Common mistakes to avoid
- Filing Form B1 as a non-resident — wrong form generates IRAS queries and delays the assessment.
- Missing the IR21 tax clearance for departing employees — the employer can be held liable for any tax owed.
- Assuming the NOR scheme is still available — it closed to new entrants from YA 2024.
- Forgetting to claim earned-income relief — the basic relief applies automatically to residents under 55.
- Failing to factor in the 15% flat rate for non-residents on directors' fees, even where the underlying employee is resident.

FAQs
What is the difference between resident and non-resident tax in Singapore?
Residents pay 0% to 24% progressive on chargeable income with personal reliefs. Non-residents pay 15% flat on employment income (or resident rate if higher) and 24% on directors' fees and other Singapore-sourced income.
How is residency determined?
Section 2 of the Income Tax Act 1947 — physical presence or employment in Singapore for at least 183 days in the preceding calendar year qualifies an individual as resident. Administrative concessions exist for 2-year and 3-year assignments.
What is IR21 and when is it filed?
IR21 is the tax-clearance return employers file for departing employees. Section 68(8) requires filing at least one month before the cessation date. The employer must withhold tax on the final salary until clearance.
Are foreign-sourced income items taxable in Singapore?
Generally no for individuals — section 13(7A) and following exempt most foreign-sourced income received in Singapore by individuals. Specific receipts (e.g., partnership income) can be different.
Is the Not Ordinarily Resident (NOR) scheme still available?
No. The NOR scheme closed to new entrants from YA 2024. Existing NOR taxpayers continue under their existing entitlement until the scheme runs off.
