What is the difference between tax relief and tax deduction in Singapore?

Tax Relief vs. Tax Deduction in Singapore

In Singapore's income tax system, both tax relief and tax deductions reduce the amount of income subject to tax, but they function differently in the calculation process. While the provided knowledge focuses heavily on CPF and SRS mechanics, general Singapore tax principles (governed by IRAS) distinguish these terms.

Tax Deduction (General Principle)

A tax deduction is an amount subtracted directly from your assessable income to arrive at your net income. This is a direct reduction of the income base before applying reliefs or personal reliefs.

Tax Relief (General Principle)

A tax relief is an amount subtracted from your net income (after deductions) to arrive at your taxable income. Tax reliefs are typically capped. For instance, the combined total tax relief cap (including reliefs like earned income relief, CPF relief, etc.) is generally S$80,000 (as per general tax knowledge, though not explicitly detailed in the CPF/SRS figures provided).

Practical Application Context (CPF/SRS)

When looking at CPF and SRS:

• CPF Contributions: Employee CPF contributions (up to the mandatory ceiling, e.g., 20% of salary up to the prevailing wage ceiling) are generally treated as a form of tax relief that reduces your overall taxable income, subject to the total relief cap.
• SRS Contributions: Contributions to the Supplementary Retirement Scheme (SRS) are also treated as a tax relief. Citizens/PRs can contribute up to S$15,300 per year, which reduces their taxable income, subject to the overall S$80,000 cap.

In summary, while both lower your tax bill, deductions reduce the income base, and reliefs reduce the income base after deductions, both ultimately lowering the final amount taxed at your marginal rate. For most personal finance planning related to CPF/SRS, these amounts function as reliefs that reduce assessable income.
