Iggy’s Journal: A S$15,300 SRS Top-Up Saves S$456 at One Income and S$3,060 at Another. Which One Is Yours?

Tue 13 Oct 2026 | Afternoon

The Numbers

The same S$15,300 SRS contribution saves S$456 in tax at S$40,000 of chargeable income and S$3,060 at S$320,000. The amount put in is identical. The saving is decided by the tax band the contribution comes out of. The exit matters as much as the entry.

SRS cash earning 0.05% sits against a six-month T-bill that cleared at 1.9% on 8 October 2026.

My Personal Take

S$456 is 3.0% of S$15,300 and S$3,060 is 20.0%, so the same contribution returns about 6.7 times as much at the higher income. Idle cash is the second sum. S$15,300 at 0.05% earns S$7.65 a year, and at 1.9% it earns S$290.70, a gap of S$283.05 each year. Relief arrives once, and the yield gap recurs every year the cash sits there. In the episode I set the two against each other at both incomes.
