My 3 favourite ways to reduce tax in Singapore

How to legally pay less tax before 31 December (your future self will thank you)

It’s that time of year again – Christmas lights are up, Mariah Carey’s defrosting… and IRAS is quietly waiting to collect your hard-earned money.

But before you resign yourself to “aiya, bo bian lah,” here’s the good news: you still have a few weeks to legally reduce how much tax you pay – by topping up your CPF and SRS accounts.

Think of it as sending a year-end bonus to your future self instead of to the taxman.

There are 3 powerful levers Singaporeans can still pull before year-end to reduce tax:

CPF top-ups, SRS contributions, and donations.

Let’s start with the most straightforward one: CPF top-ups.

When you top up your own CPF Special Account or Retirement Account, you can claim up to $8,000 in tax relief. 

On top of that, if you top up your parents’, spouse’s or siblings’ (if certain conditions are met) CPF accounts, you get another $8,000 in relief.

That’s $16,000 total.

Why does this matter? Because every dollar of tax relief reduces your taxable income. 

If you’re in a 11.5% tax bracket, maxing out that $16,000 relief saves you about $1,840 immediately. 

That’s money you don’t send to IRAS – and instead, it goes into an account earning up to 5% interest, backed by the government.

Yes, the money is locked up until later in life. But that’s the trade-off: short-term flexibility for long-term certainty. You’re not just saving tax – you’re strengthening your retirement safety net.

Next is SRS (Supplementary Retirement Scheme), which works differently.

If you’re a Singaporean or PR, you can contribute up to $15,300 a year. If you’re a foreigner working here, the limit is $35,700. 

Whatever you contribute comes straight off your taxable income for the year.

The real advantage of SRS isn’t just tax relief – it’s when you pay tax. You’re deferring tax from your highest-earning years to your retirement years, when your income is usually lower. 

When you eventually withdraw from SRS, only 50% of the withdrawals are taxable, and you can spread them out over up to 10 years.

On top of that, SRS money can be invested – in ETFs, REITs, bonds, or unit trusts. So instead of paying tax now and investing what’s left, you invest first and deal with tax later. 

The key here is to invest because SRS only gives you 0.05% per annum in interest. Many just top up and leave it be. 

If you invest and it grows at 10% p.a., your $15,300 will become $102,930.75 in 20 years.

Imagine if you top up yearly and continue investing. By the time you retire, you’ll have another set of retirement funds to rely on.

Let me know if you need help investing these funds, I’ll be happy to help!

Finally, there’s donations – the most overlooked tax relief in Singapore.

If you donate to an IPC-registered charity, you get a 250% tax deduction. 

Donate $1,000, and IRAS treats it like you donated $2,500 when calculating your tax.

In other words, the government is effectively sharing the cost of your generosity. You support causes you care about, and your tax bill goes down at the same time. 

The key is that the donation must be made by 31 December, and the charity must be IPC-approved.

Here’s the mindset shift most people miss.

Paying tax gives you nothing back personally. The money is gone, full stop.

CPF, SRS, and donations all let you redirect that money instead:

  • CPF turns tax into guaranteed retirement income
  • SRS turns tax into long-term, tax-deferred investments
  • Donations turn tax into real-world impact for causes you believe in

 

None of these are “free money.” You’re still parting with cash. But you’re choosing where it goes – instead of letting the default option decide for you.

That choice alone can be worth thousands of dollars a year.

If you remember only one thing, let it be this: tax planning in Singapore is time-based.

Once 31 December passes, the door closes. No appeals, no extensions, no “I didn’t know.” IRAS is very fair – and very firm.

You don’t need to max out everything. But doing something – CPF, SRS, or donations – is almost always better than doing nothing.

Make the decision while you still can!

Stay informed, stay intentional, and let your money work harder – even at the very end of the year.
