Singapore Tax Guide & Calculator for EP, S Pass & Work Permit Holders (2026)
Singapore is globally renowned as a premier destination for global executives, tech talent, and expatriates holding Employment Passes (EP), Overseas Networks & Expertise Passes (ONE Pass), S Passes, or Work Permits. However, calculating your net take-home pay requires a clear understanding of the quantitative 183-day tax residency rule, non-resident flat tax benchmarks, tax treatment of housing allowances and stock options, and mandatory tax clearance via Form IR21.
1. EP Tax Residency & 183-Day Rule
Under IRAS statutory rules, an expatriate holding an Employment Pass, S Pass, or ONE Pass is classified as a Singapore tax resident if they physically stay or work in Singapore for 183 days or more in a calendar year.
2. Tax Rate Benchmark: Progressive vs 15% Flat
The tax calculation for foreign professionals varies dramatically based on residency status:
| Status | Duration of Employment | Applicable Tax Rates | Personal Reliefs |
|---|---|---|---|
| Exempt Non-Resident | 60 days or less | 0% Tax Exempt (Short-term exemption) | None |
| Non-Resident | 61 to 182 days | Flat 15% on employment income OR resident progressive rates (whichever tax is higher) | Ineligible for personal reliefs |
| Tax Resident | 183 days or more | Progressive resident rates (0% to 24%) | Eligible for Earned Income, SRS, Parent reliefs |
3. Taxing Expat Allowances & Stock Options (ESOP)
In Singapore, gross assessable employment income includes not just base salary, but all cash and non-cash benefits:
- Housing Allowances: Cash accommodation allowances provided by employers are fully taxable. Company-leased apartments are taxed based on the annual value of the property minus rent paid by employee.
- Stock Options & Restricted Stock Units (RSU): Gains derived from unexercised stock options or unvested RSUs are taxable in the year of exercise or vesting.
- Deemed Exercise ("Deemed Exit Rule"): When an EP holder leaves Singapore, unvested RSUs or unexercised ESOPs are deemed exercised and subject to tax clearance under Form IR21 before departure.
4. Foreign SRS Tax Relief (Up to S$35,700)
To compensate for lack of CPF participation, the Ministry of Finance allows foreign EP holders to make contributions to the Supplementary Retirement Scheme (SRS) up to S$35,700 per year.
5. Form IR21 Tax Clearance Process
When a foreign employee resigns, transfers, or leaves Singapore, the employer must complete Form IR21 at least 1 month prior to departure. The employer withholds all salary payments until IRAS issues a Clearance Directive, ensuring all taxes are paid before leaving Singapore.
