What are the SRS caps?

Singapore citizens and Permanent Residents can contribute up to S$15,300 per year, while foreigners can contribute up to S$35,700 per year. Contributions above the cap are not allowed and earn no relief.

How does SRS save tax?

Every dollar you contribute (up to the cap) is deducted from your assessable income, so your tax saving is your contribution multiplied by your marginal income-tax rate. A higher earner saves more per dollar contributed.

Is there an overall personal income tax relief cap?

Yes. Total personal income-tax reliefs are capped at S$80,000 per year of assessment. If your other reliefs already reach that ceiling, additional SRS relief may not reduce your tax further. This tool shows the SRS relief alone.

Why is the foreigner cap higher?

Foreigners are not eligible for CPF, which itself attracts tax relief for citizens and PRs. The higher SRS cap (S$35,700) is set at the citizen cap multiplied by a factor that broadly compensates for the absence of CPF relief.

Singapore SRS Contribution Calculator

The Supplementary Retirement Scheme (SRS) lets Singapore taxpayers set aside money for retirement while reducing their taxable income today. This free calculator applies the correct annual cap for your residency status and shows the income-tax saving your contribution unlocks.

How it works

SRS relief is dollar-for-dollar: each dollar contributed (up to the cap) lowers your assessable income, so the tax you save is simply your contribution times your marginal rate:

allowed       = min(your contribution, cap)
cap           = 15,300 (citizen / PR)  or  35,700 (foreigner)
tax saving    = allowed x marginal income-tax rate

Because Singapore uses a progressive schedule, the saving per dollar grows with income — a 22% marginal earner saves 22 cents on the dollar, while a lower-band earner saves less.

Example

A foreigner contributes S$40,000. The cap limits this to S$35,700. At a marginal rate of 22%, the income-tax saving is 35,700 × 0.22 = S$7,854. A citizen contributing the same amount would be capped at S$15,300, saving S$3,366 at the same rate. Remember the overall S$80,000 relief ceiling may limit total reliefs.
