Determination of Chargeable Income Under the Income Tax Act 1947
The Income Tax Act 1947 establishes a clear framework for the ascertainment of chargeable income, which is fundamental to the computation of tax liability for any person in Singapore. Section 38 explicitly defines chargeable income as the residual amount after deducting all allowable reliefs and deductions from the assessable income for a given year of assessment. This provision ensures that taxpayers are taxed only on their net income after legitimate reductions, thereby preventing over-taxation and promoting fairness in the tax system.
"The chargeable income of any person for any year of assessment is the remainder of the person’s assessable income for that year after the reliefs and deductions allowed in this Part have been made." — Section 38, Income Tax Act 1947

This mechanism addresses the problem of accurately reflecting a taxpayer’s true economic capacity to pay tax by systematically allowing deductions and reliefs that recognize personal circumstances and contributions to social schemes.
Reliefs and Deductions for Resident Individuals
Section 39 of the Act provides detailed provisions on the types of deductions available to resident individuals. These include earned income deductions, reliefs for spouses and children, contributions to the Central Provident Fund (CPF), insurance premiums, and other personal reliefs. The rationale behind these deductions is to acknowledge the financial responsibilities and social contributions of individuals, thereby reducing their taxable income accordingly.
"In the case of an individual resident in Singapore in the year of assessment, there is allowed a deduction, in respect of earned income, which is — (a) in the case of an individual not falling within any other paragraph, the sum of $1,000 or the amount of the earned income; ... whichever is less." — Section 39(1), Income Tax Act 1947

By allowing such deductions, the legislation mitigates the tax burden on individuals who support dependents or contribute to national social security schemes. This approach promotes social equity and incentivizes compliance with social policies.
However, to prevent excessive claims that could erode the tax base, Section 39A imposes a cap on the total amount of deductions an individual can claim under Section 39.
"Despite anything in section 39 or the Fifth Schedule, for the year of assessment 2018 and every subsequent year of assessment, the total amount of all deductions allowable to any individual under section 39 must not exceed $80,000 for that year of assessment." — Section 39A, Income Tax Act 1947

This cap addresses the problem of potential abuse or disproportionate claims of reliefs, ensuring that deductions remain within reasonable limits and maintain the integrity of the tax system.
Preferential Tax Treatment for Non-Resident Public Entertainers
Sections 40A and 40B introduce special tax relief provisions targeted at non-resident individuals engaged in specific activities in Singapore. Section 40A applies to non-resident public entertainers, allowing their chargeable income attributable to such activities to be taxed at a reduced flat rate of 15%. This preferential rate simplifies tax administration and provides certainty for entertainers who may have transient or limited income sources in Singapore.
"where the only source of income in Singapore is such activity as a public entertainer, by reduction of the rate of tax to 15% on every dollar of the chargeable income;" — Section 40A(2)(a), Income Tax Act 1947
Verify Section 40A(2) in source document →
This provision addresses the practical difficulties in taxing non-resident entertainers who may have fluctuating incomes and limited ties to Singapore, thereby encouraging cultural and entertainment activities within the country.
Preferential Tax Treatment for Non-Resident Employees
Similarly, Section 40B extends a comparable preferential tax rate to non-resident employees whose only source of income in Singapore is employment income. The flat 15% tax rate on chargeable income attributable to such employment simplifies compliance and reduces administrative burdens for both taxpayers and the tax authorities.
"where the only source of income in Singapore is such activity as a non-resident employee, by reduction of the rate of tax to 15% on every dollar of the chargeable income;" — Section 40B(2)(a), Income Tax Act 1947
Verify Section 40B(2) in source document →
This provision solves the problem of complex tax calculations for non-resident employees who may be subject to multiple tax jurisdictions, thereby enhancing Singapore’s attractiveness as a destination for foreign talent.
Tax Relief for Non-Resident Supplementary Retirement Scheme (SRS) Members
Section 40C addresses the tax treatment of non-resident individuals withdrawing from their Supplementary Retirement Scheme (SRS) accounts. It provides for a reduced tax rate of 15% on chargeable income attributable to such withdrawals when these withdrawals constitute the person’s only source of income in Singapore.
"where the withdrawals from the person’s SRS account are the person’s only source of income, by reduction of the rate of tax to 15% on every dollar of the chargeable income;" — Section 40C(2)(a), Income Tax Act 1947
Verify Section 40C(2) in source document →
This provision facilitates the tax-efficient repatriation of retirement savings by non-residents, encouraging participation in the SRS and supporting retirement planning while maintaining Singapore’s competitive tax environment.
Tax Relief for Non-Residents with Multiple Income Sources
Section 40D caters to non-resident individuals deriving income from two or more sources among public entertainer income, employment income, and SRS withdrawals. It allows for proportional reduction of tax rates applicable to each source, as specified under Sections 40A, 40B, and 40C respectively.
"where the person only derives the relevant income in Singapore, by reduction of the rate of tax to the rate specified under section 40A, 40B or 40C (as the case may be) on every dollar of the chargeable income attributable to the source of income mentioned in subsection (1)(a), (b) or (c), respectively;" — Section 40D(2)(a), Income Tax Act 1947
Verify Section 40D(2) in source document →
This provision resolves the complexity arising from multiple income streams by applying appropriate tax rates to each source, ensuring equitable and administratively feasible taxation for non-residents.
Procedural Requirements for Claiming Deductions and Reliefs
Section 41 imposes procedural obligations on individuals claiming any deduction or relief under this Part. It mandates that claims be made on the proper form and supported by particulars and proof as required by the Comptroller of Income Tax.
"Every individual who claims any deduction or relief under this Part must make his or her claim on the proper form." — Section 41(1), Income Tax Act 1947
Verify Section 41(1) in source document →
"Such deduction or relief must be granted if the claim contains such particulars and is supported by such proof as the Comptroller may require." — Section 41(2), Income Tax Act 1947
Verify Section 41(2) in source document →
These procedural safeguards ensure that claims are substantiated and verifiable, preventing fraudulent or erroneous deductions and maintaining the integrity of the tax assessment process.
Integration with Other Statutory Schemes
The Income Tax Act 1947’s provisions on ascertainment of chargeable income are closely integrated with other statutory frameworks. For instance, Section 39 references the Central Provident Fund Act 1953 to allow deductions for CPF contributions, recognizing mandatory social security payments as legitimate deductions.
"Where an individual has paid money in accordance with section 18 of the Central Provident Fund Act 1953 to the retirement account or special account..." — Section 39(2)(3), Income Tax Act 1947

Similarly, the Employment of Foreign Manpower Act 1990 is referenced concerning levy payments, ensuring that statutory levies are appropriately accounted for in tax computations. Furthermore, Sections 40A through 40D reference Section 10G of the Income Tax Act 1947 concerning SRS withdrawals, harmonizing tax treatment across related provisions.
This cross-referencing solves the problem of fragmented tax treatment by creating a cohesive legal framework that aligns tax reliefs and deductions with broader social and employment policies.
Conclusion
The ascertainment of chargeable income under the Income Tax Act 1947 is a comprehensive process that balances the need for accurate tax computation with fairness and administrative efficiency. By defining chargeable income as assessable income less allowable reliefs and deductions, the Act ensures taxpayers are taxed on their true net income. The detailed provisions for resident individuals, non-resident entertainers, employees, and SRS members reflect Singapore’s commitment to equitable taxation tailored to diverse taxpayer circumstances.
Procedural requirements for claims and integration with other statutory schemes further enhance the robustness and coherence of the tax system. Collectively, these provisions address practical challenges in tax administration, prevent abuse, and promote compliance, thereby underpinning Singapore’s effective and fair income tax regime.
