Rates and Rules of Singapore Tax: How Does Personal Tax and Corporate Tax in Singapore Work?
Singapore is one of the few places in the world where a 17% corporate tax rate, zero capital gains tax, and zero dividend tax exist within the same jurisdiction, and that combination is the result of a tax policy deliberately built to attract business owners to incorporate a company, retain talent, and sustain one of Asia’s most competitive economies.
This article provides a current breakdown of how Singapore’s personal income tax, corporate tax, filing deadlines, and compliance requirements work for 2026, so that businesses and individuals are fully prepared to meet their obligations and make complete use of every benefit available to them.
What is the Personal Income Tax in Singapore?
Personal income tax in Singapore is a direct tax imposed by the government on income earned by individuals within the country, administered by the Inland Revenue Authority of Singapore (IRAS) and assessed annually through a structured filing process known as the Year of Assessment.

Personal Income Tax Liability in Singapore
Any individual who resides in Singapore and earns from a job or makes a profit from a business is liable for this tax. The tax rates depend on the income amount and the residency status of the person, on whether the individual is a citizen, permanent resident, or a foreigner.
-
Personal Income Tax Rates for Tax Residents in Singapore
Singapore citizens, permanent residents, and foreigners who have stayed or worked in Singapore for at least 183 days in the preceding calendar year are classified as tax residents by IRAS. Tax residents are taxed at progressive rates: starting at 0% on the first S$20,000 of chargeable income and capped at 24% on income exceeding S$1,000,000 for the Year of Assessment 2026.
-
Personal Income Tax Rates for Non-Residents in Singapore
Non-residents’ employment income is taxed at either 15% or the progressive resident rates, whichever is higher, while all other income, including director’s fees and consultancy income, is taxed at 24% for YA 2026. Foreign professionals providing services in Singapore are subject to withholding tax at 15% of gross income or 24% of net income, and qualifying public entertainers benefit from a concessionary rate of 10% on their Singapore-sourced income.
What is the Corporate Tax in Singapore?
Corporate tax in Singapore is a tax on the net profits a company earns from its business activities within the country, calculated on chargeable income for each Year of Assessment and governed by the Income Tax Act under the administration of IRAS.
-
Corporate Tax System in Singapore
The low corporate tax in Singapore is considered one of the most critical factors for the influx of investors in the city-state. Thus, it has been contributing a lot to the growing economy.
The city-state had a single-tier tax system since 2003, which means that companies are only liable for the tax they make in Singapore.
Singapore Corporate Tax Rate
The corporate tax rate in Singapore is a flat 17%. Remember, this is just the ‘headline tax rate,’ and the real amount a company pays is generally lower. This is because of tax incentives and other depreciation rules.
-
Corporate Tax Rate in Singapore
Singapore’s corporate tax rate is 17% on chargeable income; however, the effective rate most companies pay is considerably lower, as deductible business expenses reduce the actual liability. For 2026, IRAS has introduced a Corporate Income Tax (CIT) Rebate of 40% of tax payable, capped at S$30,000, providing further relief to qualifying companies.
-
Key Features of Singapore’s Corporate Tax System
Singapore’s corporate tax system operates on a one-tier structure; profits are taxed once at the company level, and dividends paid to shareholders carry no further tax liability. Income is taxed only on Singapore-sourced earnings, with no capital gains tax and no dividend tax, making it one of the most transparent and business-friendly corporate tax frameworks in the Asia-Pacific region.
What Tax Exemptions and Incentives are Available in Singapore?
IRAS offers two primary tax exemption schemes for companies: the Start-Up Tax Exemption (SUTE) Scheme for newly incorporated companies and the Partial Tax Exemption (PTE) Scheme for all other qualifying companies.

Frequently Asked Questions
If your employer participates in the AIS, they submit your income information directly to IRAS, which means your employment income is pre-filled in your tax return, and you are generally not required to file separately. However, you are still required to log in to myTax Portal to verify the pre-filled information and declare any additional sources of income, such as rental income or freelance earnings, by 18 April 2026.
Rental income derived from properties located in Singapore is taxable and must be declared in your annual income tax return, regardless of your residency status. For non-residents, rental income is taxed at the rate of 24%, while tax residents are assessed at the applicable progressive resident rates after allowable deductions, such as mortgage interest, maintenance fees, and property tax, are applied against the gross rental income.
Singapore operates on a territorial basis of taxation, which means income earned outside Singapore is generally not subject to tax, even if it is remitted into a Singapore bank account by an individual. The key exception applies to income received through a partnership in Singapore or foreign income brought into Singapore by a tax resident individual through certain qualifying structures, which may be assessed depending on the specific circumstances.
Late filing or non-filing of personal income tax returns is an offence under Singapore law. IRAS may issue an estimated Notice of Assessment, impose a composition fine of up to S$5,000, or, in serious cases of repeated non-compliance, issue a summons requiring the individual to attend court. Filing accurately and on time through myTax Portal by 18 April 2026 remains the most effective way to avoid any enforcement action.
Tax reliefs in Singapore are only available to individuals who qualify as tax residents for the relevant Year of Assessment. Foreigners who meet the 183-day residency threshold are entitled to claim applicable reliefs, including CPF relief, course fees relief, and parent relief, provided the qualifying conditions for each relief are met. Non-residents are not eligible to claim any personal tax reliefs and are taxed on their Singapore-sourced income.
Singapore maintains an extensive network of over 90 Avoidance of Double Taxation Agreements (DTAs) with countries across Asia, Europe, and the Americas, ensuring that income earned by Singapore tax residents in treaty countries — and vice versa — is not taxed twice.
A Notice of Assessment is the official tax bill issued by IRAS, which sets out the amount of tax payable for the Year of Assessment based on the income and reliefs declared. Upon receiving the NOA, taxpayers should review the reported income, reliefs, and tax computation carefully — and if the assessment is incorrect, an amendment can be requested via myTax Portal within 30 days of the NOA date.
