When a foreign or PR employee leaves a Singapore employer, the employer must file IR21 and withhold the final month's salary, leave encashment, and bonus pending IRAS tax clearance. This 2027 calculator estimates the withholding amount based on year-to-date income, projected final payments, and residency status — useful for both employers and employees needing accurate cash-flow expectations.

What Is IR21 Tax Clearance in 2027
IR21 is the Notification of a Non-Citizen Employee's Cessation of Employment that Singapore employers must file with IRAS at least one month before a foreign or PR employee leaves the country, ceases employment, or transfers to an overseas position. During this period the employer must withhold all monies due — final salary, bonus, leave encashment, gratuity — until IRAS issues tax clearance. The withholding ensures any outstanding income tax is paid before the employee leaves Singapore. Singapore citizens are exempt from IR21 because they remain reachable for tax matters.

Worked Example — EP Holder Leaving Mid-Year
An Employment Pass holder earning SGD $8,000/month leaves on 31 July 2027 after 7 months. YTD income: SGD $56,000. Final month: SGD $8,000. Bonus: SGD $15,000. Leave encashment: SGD $4,000. Total 2027 income: SGD $83,000. As a tax resident (183+ days in 2026 carried forward via 2-year rule), tax payable ≈ SGD $4,150. The employer withholds the final SGD $27,000 (salary + bonus + leave) until clearance. After IRAS clears, SGD $4,150 goes to IRAS, SGD $22,850 returns to the employee.
Resident vs Non-Resident Tax Rates in 2027
Tax residency dramatically affects the IR21 outcome. Resident rates use the progressive scale starting at 0% on the first SGD $20,000 and rising to 24% above SGD $1,000,000. Non-residents present 60–182 days are taxed at 15% flat or resident rates, whichever is higher. Non-residents present under 60 days are tax-exempt unless directors, public entertainers, or short-term consultants. Determining residency at IR21 time requires the employer to count actual presence days in Singapore during the year of cessation — IRAS uses passport stamps when in doubt. Misclassification triggers underwithholding penalties of 200% of the tax due.
What Employees Should Do Before Their Last Day
Five checklist items: (1) Confirm with HR that the IR21 filing has been triggered — request a copy of the filed form. (2) Track your physical presence days carefully if 2027 is borderline 183 days. (3) If you have unutilised SRS, decide on withdrawal strategy before leaving — Singapore-source-only income post-departure attracts non-resident rates. (4) Settle any outstanding CPF top-up tax relief claims — they reduce IR21 tax. (5) Request your Notice of Assessment (NOA) issuance preference. Tax clearance typically completes in 7–14 working days; IRAS expedited cases (under SGD $5,000) can clear in 3 days via the IR21 e-service.
