SRS Tax Savings for a $100,000 Income Earner in Singapore

At $100,000 chargeable income, a 35-year-old Singapore citizen or PR is in the 11.5% bracket, where SRS starts to pay clearly. Contributing the full $15,300 SRS cap saves an estimated $1,760 in income tax this year, cutting the effective tax rate from 5.7% to 3.9%. The figures assume $100,000 is chargeable income (after CPF relief and other reliefs), stays flat, and the full cap is contributed every year.

The whole $15,300 comes off income taxed at 11.5%, so every dollar contributed saves 11.5 cents of tax.

Contributing every year from age 35 to 64, the penalty-free age for anyone making a first SRS contribution from 1 July 2026, and investing at an assumed 5% annual return, grows the account to an estimated $1,001,214: $443,700 of contributions and $557,514 of investment gains. Left in cash at typical SRS interest of about 0.05%, most of those gains disappear.

Withdrawn evenly over 10 years from 64, that is $100,121 a year, of which half ($50,061) is taxable. That costs about $1,254 a year, an effective 1.3% on each withdrawal, against the 11.5% marginal rate saved on the way in. Total withdrawal tax comes to roughly $12,543.

Over 29 years of contributions, total tax saved is about $51,025. After withdrawal tax, SRS itself leaves you roughly $38,483 better off. The investment gains are not really an SRS benefit: Singapore does not tax capital gains, so you would earn similar returns investing the same money outside SRS, without the lock-up until 64.
