Singapore CPF and SRS Explained: The Tax Levers Most Expats Never Touch

By Paulo Horta · Published July 2026 · 9 min read

Our Moving to Singapore guide covers CPF in passing, mostly to explain why Employment Pass holders don't pay into it. But there's a second scheme — the Supplementary Retirement Scheme, or SRS — that barely gets mentioned anywhere, and it's arguably more useful to expats than to the locals it was originally designed for. If you're on an EP and assumed you have no tax-advantaged savings options in Singapore because you don't touch CPF, this is worth ten minutes of your time.

CPF, Briefly: Who Actually Pays It

For Singapore citizens and Permanent Residents aged 55 and under, CPF takes a combined 37% of ordinary wages — 20% from the employee, 17% from the employer — up to the ordinary wage ceiling of $6,800 a month. It's mandatory, it's split across three accounts (Ordinary, Special, and MediSave), and the rate steps down progressively after age 55. If you're an Employment Pass holder, none of this applies to you: no deduction, no employer top-up, no CPF account at all. That's a genuine difference in take-home pay versus an equivalent local hire — but it also means no automatic retirement savings vehicle either.

SRS: The Scheme Foreigners Can Use More Than Locals

The Supplementary Retirement Scheme lets anyone — citizen, PR, or foreigner on any pass — open an account and contribute pre-tax money that's deducted directly from chargeable income, similar in spirit to a 401(k) or a pension contribution elsewhere. Because SRS exists to make up for the fact that some people don't get CPF's tax relief, the contribution caps are explicitly asymmetric:

That's not a typo — foreigners get more than double the local cap, precisely because they aren't accumulating CPF savings in parallel. An EP holder earning $150,000 who maxes out SRS shields $35,700 from Singapore's progressive tax scale in the year they contribute — at the higher brackets, that's a saving well into five figures over a few years. Withdrawals are taxed, but only 50% of what you take out counts as chargeable income, and growth inside the account is tax-free until then.

The Catch: Early Withdrawal

SRS money is meant to stay in the account until the statutory retirement age at the time of your first contribution. Withdraw early for any reason other than death or a small list of medical exceptions, and you lose the 50% concession — the full withdrawal becomes taxable, plus a 5% penalty on top. This is precisely why SRS makes sense for money you're confident you won't need before then, and not as a general savings account with a tax perk attached.

CPF Cash Top-Ups: The Other Lever, for Citizens and PRs

If you do have a CPF account, topping it up with cash — for yourself or eligible family members like parents or a spouse — earns tax relief of up to $8,000 for your own top-up and another $8,000 for family top-ups, for a combined $16,000 a year. One change for 2026 worth knowing: top-ups that also qualify for the government's Matched Retirement Savings Scheme grant no longer count toward this relief from Year of Assessment 2026 onward, so the two benefits can't be stacked the way they previously could in some cases.

Whether you use CPF top-ups, SRS, or both, remember that Singapore caps total personal income tax reliefs at $80,000 a year across every relief category combined — a ceiling that mostly affects very high earners layering multiple reliefs at once.

Worked Example: $150,000 Gross, Employment Pass Holder

Without any reliefs, a $150,000 salary in Singapore sits in the upper-middle of the tax scale, with an effective rate typically in the 12-15% range once personal reliefs are applied. Contributing the full $35,700 to SRS reduces chargeable income by that amount before tax is calculated — at a marginal rate around 15-18% for income in that band, the immediate tax saving is roughly $5,000-6,500 in the contribution year alone, on top of tax-free growth until withdrawal.
