The Inland Revenue Authority of Singapore (IRAS) classifies individuals into three categories for tax purposes, each with different tax treatment:
| Status | Criteria | Tax Treatment |
|---|---|---|
| Tax Resident | 183+ days in Singapore in a calendar year (or 3 consecutive years) | Taxed on income derived from Singapore + foreign income remitted to Singapore; progressive resident rates apply |
| Non-Resident | Fewer than 183 days in a calendar year | Taxed only on Singapore-sourced income at non-resident rates (15-24%) |
| Resident (Transitional) | 183+ days over 2 consecutive years (crossing year-end) | Taxed as resident for both years |
Short-term visitors who stay 60 days or fewer in a calendar year are generally exempt from Singapore tax on employment income. However, this exemption does not apply to directors, public entertainers, or professionals. Short-term business visitors from treaty countries may also benefit from the 183-day employment article to avoid Singapore taxation.
Singapore uses a progressive tax system with relatively low top rates compared to other developed economies. The following rates apply to tax residents:
| Chargeable Income (SGD) | Rate | Tax Payable (SGD) |
|---|---|---|
| First 20,000 | 0% | 0 |
| Next 10,000 (20,001-30,000) | 2% | 200 |
| Next 10,000 (30,001-40,000) | 3.5% | 350 |
| Next 40,000 (40,001-80,000) | 7% | 2,800 |
| Next 40,000 (80,001-120,000) | 11.5% | 4,600 |
| Next 40,000 (120,001-160,000) | 15% | 6,000 |
| Next 40,000 (160,001-200,000) | 18% | 7,200 |
| Next 40,000 (200,001-240,000) | 19% | 7,600 |
| Next 40,000 (240,001-280,000) | 19.5% | 7,800 |
| Next 40,000 (280,001-320,000) | 20% | 8,000 |
| Above 320,000 | 24% |
For a resident earning SGD 150,000, the total tax is approximately SGD 9,950—an effective rate of just 6.6%. At SGD 300,000, the total tax is approximately SGD 33,950—an effective rate of 11.3%. These rates are significantly lower than those in most Western countries, making Singapore an attractive posting for expatriates.
Non-residents are taxed only on Singapore-sourced income and at different rates:
The Central Provident Fund (CPF) is Singapore's mandatory social security savings scheme. Foreign workers holding Employment Passes, S Passes, or Work Permits are generally exempt from CPF contributions. However, Permanent Residents (PRs) must contribute to CPF.
For PRs, the contribution rates phase in over two years:
| PR Year | Employee Rate | Employer Rate | Total |
|---|---|---|---|
| 1st year | 5% | 4% | 9% |
| 2nd year | 15% | 9% | 24% |
| 3rd year onward | 20% | 17% | 37% |
CPF contributions are capped at a monthly salary ceiling of SGD 6,800 (as of 2024, increasing to SGD 7,400 in 2025 and SGD 8,000 in 2026). This means the maximum monthly CPF contribution for a 3rd-year PR is SGD 2,960 (37% of SGD 8,000). CPF contributions are tax-deductible for the employee portion, reducing taxable income.
The NOR scheme provides tax benefits for foreign professionals who become Singapore tax residents but have not been resident in the preceding three years. Key benefits include:
To qualify, you must have been a tax resident of Singapore for at least one of the preceding three years and earn at least SGD 160,000 in the relevant year. NOR status is granted for five years and can be renewed. This scheme is particularly valuable for executives who travel extensively, as days spent outside Singapore on business reduce the taxable portion of employment income.
Foreigners employed by Singapore companies to develop markets outside Singapore can qualify for the Area Representative scheme. Under this scheme, only the portion of employment income related to Singapore duties is taxed. This is similar to the NOR time-apportionment benefit but has less stringent qualifying conditions and is available indefinitely.
Singapore taxes foreign-sourced income only when it is remitted to Singapore. Even then, foreign-sourced dividends, foreign branch profits, and foreign-sourced service income are taxed only if the remittance is received by a Singapore tax resident and the headline tax rate in the source country is less than 15%. In practice, most foreign income remitted to Singapore by individuals is not taxed.
This territorial approach means that foreign workers who keep their foreign investment income outside Singapore generally pay no Singapore tax on it. This is a significant advantage for expats with international investment portfolios or rental properties in their home countries.
Singapore tax residents can claim various reliefs to reduce taxable income:
| Relief Type | Maximum Amount (SGD) | Conditions |
|---|---|---|
| Earned Income Relief | 1,000 (under 55) / 8,000 (55+) | Automatic for employment income |
| SPS (SRS) Contribution | 15,300 (foreigners) | Voluntary contribution to Supplementary Retirement Scheme |
| Course Fees Relief | 5,500 | For approved courses that improve skills |
| CPF Cash Relief | Up to 8,000 | For cash top-ups to CPF Special Account |
| Parent Relief | Up to 9,000 | For supporting parents/grandparents in Singapore |
| Child Relief | 4,000-8,000 per child | For legitimate children |
| Working Mother's Child Relief | 15-25% of earned income | For working mothers with Singaporean children |
The total relief claim is capped at SGD 80,000 per year. The Supplementary Retirement Scheme (SRS) is particularly valuable for foreign workers, as it allows pre-tax contributions that reduce current taxable income. Withdrawals after the 10-year holding period are taxed with only 50% of the withdrawal subject to tax.
Singapore imposes a 9% GST (raised from 8% in January 2024) on most goods and services. Unlike VAT in some countries, GST is a consumption tax and is not deductible for individuals. However, the overall GST burden in Singapore remains low compared to European VAT rates of 20-27%, contributing to the city-state's attractiveness for expatriates.
Singapore has over 90 comprehensive tax treaties, making it one of the best-connected jurisdictions for treaty benefits. Key treaty partners include the US, UK, Australia, China, Japan, India, and most EU countries. These treaties reduce withholding rates on cross-border income and provide residency tiebreaker rules for dual residents.
| Treaty Partner | Dividend WHT | Interest WHT | Royalty WHT |
|---|---|---|---|
| United States | 0-15% | 0-15% | 5-10% |
| United Kingdom | 0-15% | 0-15% | 0-8% |
| Australia | 0-15% | 0-15% | 5-10% |
| China | 5-12% | 7-12% | 6-10% |
| Japan | 0-10% | 0-10% | 5-7% |
| Germany | 5-15% | 0-15% | 5-8% |
Tax residents and non-residents with Singapore-source income must file an annual tax return by April 15 (paper filing) or April 18 (e-filing). If your employer participates in the Auto-Inclusion Scheme (AIS), your employment income data is transmitted directly to IRAS, simplifying the filing process. Those with only employment income from a single AIS employer and no other income may receive a No-Filing Service letter, meaning no return is required unless they have additional income to report.
Notices of Assessment are typically issued between April and September. Tax must be paid within 30 days of the Notice of Assessment. IRAS offers a 12-month interest-free installment plan for tax payments via GIRO for residents.
If you leave Singapore permanently, you must file a tax return and clear all tax liabilities before departing. Your employer is required to withhold all monies due to you until IRAS issues a Tax Clearance Certificate. This process can take several weeks, so initiate it at least one month before your departure date. If you have a property or significant assets in Singapore, additional clearance may be required.
