How to Reduce Income Tax in Singapore: 16 Ways That Work (2026)

Every March, the tax filing season opens. And every March, many Singaporeans discover that the best time to reduce their tax bill was actually the December before.

That is because most of the tax moves within your control, such as SRS contributions and CPF top-ups, must be made by 31 December of the year before you file.

So whether you are planning ahead or filing right now, this guide covers every relief, deduction, and rebate that still works in 2026, the ones that no longer exist, and who actually hits the maximum cap of $80,000 in reliefs.

All figures are as of Year of Assessment 2026 (YA2026) unless stated otherwise. This guide is general information, not personalised tax or financial advice, and thresholds can change from year to year, so check the current IRAS pages that apply to you before acting.

Key Takeaways

• The fastest ways to reduce income tax in Singapore are contributing to your SRS account (up to $15,300 for Singaporeans and PRs) and making a cash top-up to CPF (up to $16,000 in relief). Both must be done by 31 December to count for the next Year of Assessment.
• The maximum you can claim is $80,000 per Year of Assessment across all reliefs combined, a cap unchanged since 2018.
• The relief cap only starts to matter once your income exceeds roughly $100,000, and working mothers with children born before 2024 are the group most likely to hit it.
• Course Fees Relief (discontinued from YA2026) and Foreign Domestic Worker Levy Relief (lapsed from YA2025) can no longer be claimed, even though some older guides still list them.

Tax Reliefs, Deductions, and Rebates: What’s the Difference?

Reliefs and deductions reduce your chargeable income (the amount you are taxed on), while rebates directly reduce the final tax you owe.

Here is a quick way to think about it. If you earn $60,000 and claim $10,000 in reliefs, you are taxed as if you earned $50,000. A rebate, on the other hand, is subtracted from the tax bill itself.

The distinction matters because rebates offset tax dollar for dollar. The best-known one, the Parenthood Tax Rebate, can bring a middle-income family’s tax bill to zero for several years, as you will see in the list below.

Since your tax is calculated on chargeable income at progressive rates of 0% to 24%, every dollar of relief is worth more the higher your income. A dollar of relief saves 11.5 cents for someone in the $80,000 to $120,000 bracket, but only 2 cents for someone just above $20,000.

Now, let’s go through the 16 ways, grouped by life situation.

Building Up Your Retirement Funds

These three reliefs reward you for putting money aside for later, so they belong in your retirement planning rather than in a panic every March.

1) Top up your CPF in cash

Cash top-ups to your own Special Account or Retirement Account earn you up to $8,000 in CPF Cash Top-up Relief per year, and top-ups for family members (parents, grandparents, spouse, or siblings) earn up to another $8,000.

That is a combined $16,000 of relief, up from the old limit of $7,000 each before 2022.

Two conditions to note. The top-up must be in cash, not a transfer from another CPF account. And relief only applies up to the recipient’s headroom: the Full Retirement Sum for a Special or Retirement Account, and the Basic Healthcare Sum for MediSave. For a recipient aged 55 and above, you can top up their Retirement Account further, up to the Enhanced Retirement Sum, but only the part up to the Full Retirement Sum earns tax relief.

One newer wrinkle: top-ups that attract the government’s matching grants (under the Matched Retirement Savings Scheme from 2025, and the Matched MediSave Scheme from 2026) earn no tax relief, so you cannot stack the grant and the relief on the same top-up. The CPF page linked above carries the full conditions.

The bonus is that money in your Special or Retirement Account earns CPF’s higher long-term interest rates, which is why we cover top-ups in more depth in our guide to CPF retirement planning.

2) Make voluntary MediSave contributions

Whether this is even a separate lever depends on whether you are an employee or self-employed.

If you are an employee, a voluntary cash top-up to your own MediSave Account is treated as part of the same CPF Cash Top-up Relief covered above. It draws on that $8,000 self cap rather than adding to it, and the amount you can top up is limited by the Basic Healthcare Sum, which is $79,000 for 2026 for members below 65. In practice it lets you steer part of your $8,000 into healthcare savings instead of retirement, not claim a second $8,000 of relief.

If you are self-employed, you have a separate and more generous route. Voluntary contributions under the CPF Self-Employed Scheme, including to MediSave, qualify for CPF relief capped at the lowest of 37% of your net trade income, the CPF Annual Limit of $37,740, and what you actually contribute. This is why voluntary MediSave contributions matter most for the self-employed, who can use them to build up savings and cut their tax bill at the same time.

3) Contribute to your SRS account

Contributions to the Supplementary Retirement Scheme reduce your chargeable income dollar for dollar, up to $15,300 per year for Singaporeans and PRs, and $35,700 for foreigners, as of 2026.

The trade-off is that the money is locked up until the statutory retirement age that applied at your first contribution (64 for accounts opened from 1 July 2026). Withdraw early and you pay a 5% penalty, with the full amount taxable. Wait until that age, and only 50% of each withdrawal is taxable.

If you are new to the scheme, start with what the SRS is and how it works, because the money should not sit idle in the account once it is in.

Reliefs for Parents and Families

Singapore’s tax system is generous towards families, and for working mothers especially, these reliefs can wipe out the tax bill entirely.

4) Qualifying Child Relief

Parents can claim $4,000 per child under the Qualifying Child Relief, or $7,500 per child under the Child Relief (Disability).

The child must be unmarried, below 16 or studying full-time, and must not have annual income above $8,000. The relief can be split between both parents in any agreed proportion, which becomes useful for cap planning, as you will see later.

5) Working Mother’s Child Relief

This is the single biggest relief for many families, and it changed significantly from YA2025.

How much you get now depends on when your child was born or adopted:

Child order	Born or adopted before 1 Jan 2024	Born or adopted on or after 1 Jan 2024
1st	15% of mother’s earned income	$8,000
2nd	20% of mother’s earned income	$10,000
3rd and beyond	25% of mother’s earned income	$12,000

Source: IRAS and Made For Families, as of 2026.

Under the percentage regime, a mother earning $100,000 with two children could claim $35,000. Under the fixed regime, the same mother claims $18,000 for two children born after 1 January 2024.

That is $17,000 less relief for the same family profile, a shift that mainly affects higher-income mothers. For mothers earning below roughly $50,000 to $53,000 (depending on the number of children), the fixed amounts are actually more generous than the old percentages.

Two caps to remember: the combined Qualifying Child Relief and Working Mother’s Child Relief for each child cannot exceed $50,000, and your total WMCR across all children cannot exceed 100% of your earned income for the year.

6) Parenthood Tax Rebate

Unlike the reliefs above, the Parenthood Tax Rebate offsets your final tax bill directly. For a child born or adopted from 2008 onwards, it is worth $5,000 for your first child, $10,000 for your second, and $20,000 for your third and each subsequent child. You can share it with your spouse, and any unused amount carries forward until it runs out. The child must be a Singapore Citizen at birth or within 12 months after.

7) Grandparent Caregiver Relief

Working mothers whose parent, parent-in-law, grandparent, or grandparent-in-law helps look after their child (a Singapore Citizen aged 12 or below) can claim $3,000 a year.

The caregiver can be working, as long as they earned no more than $8,000 during the year. This is a recent relaxation. Until YA2023 the caregiver could not work at all, and some older guides still say so. Only one taxpayer can claim for the same caregiver.

8) Spouse Relief

If your spouse’s annual income was $8,000 or below (the threshold doubled from $4,000 in YA2025), you can claim $2,000 in Spouse Relief, or $5,500 under Spouse Relief (Disability), which has no income condition.

Reliefs for Supporting Family Members

Some of the largest reliefs available go to people looking after a parent or a sibling with a disability.

9) Parent Relief

Supporting a parent, grandparent, parent-in-law, or grandparent-in-law aged 55 and above (with annual income of $8,000 or below, a threshold that also doubled in YA2025) earns you $9,000 per dependant if you live together, or $5,500 if you live apart and spent at least $2,000 supporting them that year.

Under Parent Relief (Disability), the amounts rise to $14,000 and $10,000 respectively, with no age or income condition on the dependant.

You can claim for up to two dependants, and the relief can be shared among siblings who jointly support the same parent.

10) Sibling Relief (Disability)

If you support a sibling or sibling-in-law with a disability who lives in Singapore, you can claim $5,500 per dependant, provided they lived with you or you spent at least $2,000 supporting them that year.

Reliefs That Apply Automatically (or Almost)

You do not need to do much for these, but knowing them helps you check that your Notice of Assessment is correct.

11) Earned Income Relief

Everyone who works gets this automatically: $1,000 if you are below 55, $6,000 from 55 to 59, and $8,000 at 60 and above. Persons with disabilities receive higher amounts of $4,000, $10,000, and $12,000 respectively.

12) CPF Relief

Your compulsory employee CPF contributions are automatically claimed as relief. For someone below 55 earning at the CPF monthly salary ceiling of $8,000 (the ceiling from 1 January 2026), that is up to around $19,200 a year from ordinary wages alone, before bonuses.

There is nothing to file, but it explains why your chargeable income is already noticeably lower than your gross salary.

13) NSman Relief

All NSmen receive $1,500 a year, rising to $3,000 if you performed NS activities in the preceding year. Key command and staff appointment holders receive $3,500 and $5,000 respectively.

In recognition of their support, the wife and each parent of an NSman also receive $750 each, automatically.

Other Reliefs and Deductions

14) Life Insurance Relief

This relief exists, but most working Singaporeans cannot claim it, because it requires your total CPF contributions for the year to be below $5,000, and the relief itself is capped at the lower of a few small amounts.

If your CPF contributions are low (perhaps you took a career break, or you are a foreigner without CPF), it is worth checking. We break down exactly who qualifies for the Life Insurance Relief in a separate guide.

15) Donate to an approved charity

Donations to approved Institutions of a Public Character earn a 250% tax deduction. Donate $1,000, and your chargeable income falls by $2,500.

Budget 2026 extended the 250% rate until 31 December 2029, and deductions are automatic as long as you provide your NRIC to the charity when donating. Unused donation deductions can be carried forward for up to five years.

For pure tax arithmetic, you always give away more than you save. Donations are for giving first, with the deduction as a meaningful bonus.

16) Claim rental and employment expenses

Two deductions that many people miss.

If you earn rental income, you can deduct expenses like property tax, fire insurance, maintenance, and mortgage interest against it, or, for a residential property, simply claim a flat 15% of gross rent as deemed expenses (mortgage interest can still be claimed on top).

If you incur work expenses your employer does not reimburse, such as approved travel or subscriptions required for your job, these can be deducted as employment expenses, subject to the tax authority’s conditions.

Tax Reliefs That No Longer Exist

Two reliefs still appear in older guides but can no longer be claimed.

Course Fees Relief was discontinued from YA2026. The final year you could claim it was YA2025. The government’s support for upskilling now flows through SkillsFuture credits and subsidies instead of the tax system.

Foreign Domestic Worker Levy Relief lapsed from YA2025. Families with helpers now receive support through the migrant domestic worker levy concession instead.

If a guide you are reading lists either of these as a way to reduce your 2026 tax bill, check its other numbers carefully too.

The $80,000 Relief Cap (and Who Actually Hits It)

The personal income tax relief cap is $80,000 per Year of Assessment, and it only starts to matter once your income exceeds roughly $100,000.

Why $100,000? Because if you claim the full $80,000, your chargeable income falls to $20,000, and the first $20,000 of chargeable income is taxed at 0%. Below that income level, you would run out of tax to save before you run out of cap.

So who actually gets there? Let’s look at two profiles, both earning $100,000 a year.

Can a single person hit the $80,000 cap?

Realistically, no. Even a single person claiming aggressively falls short.

Take David, 35, single, earning $100,000 (a monthly salary of $8,000 plus a $4,000 bonus). He lives with and supports his elderly parents, and did reservist last year:

Relief	Amount
Earned Income Relief	$1,000
CPF Relief (20% employee contribution)	$20,000
Parent Relief (2 parents, staying together)	$18,000
NSman Relief (performed NS activities)	$3,000
CPF Cash Top-up (maximum, self and parents)	$16,000
SRS contribution (maximum)	$15,300
Total	$73,300

Even after locking $31,300 of his own cash into CPF top-ups and SRS, David reaches only $73,300 in reliefs. His chargeable income becomes $26,700, and his tax bill is just $134 for the year.

Without the top-ups and SRS, his chargeable income would be $58,000 and his tax about $1,810. So the $31,300 he set aside for retirement also saved him about $1,676 in tax.

One assumption to flag: the full $16,000 of top-up relief holds only if David and his parents are still below the Full Retirement Sum (see relief 1), so check that headroom before budgeting for the saving.

Working mothers are the group most likely to hit the cap

A working mother with two or more children under the percentage-based WMCR is the classic profile that exceeds the cap.

Sarah, 40, earns $100,000 and has two children born before 2024. Her parents live with her and help with caregiving:

Relief	Amount
Earned Income Relief	$1,000
CPF Relief	$20,000
Working Mother’s Child Relief (15% + 20%)	$35,000
Qualifying Child Relief (2 children)	$8,000
Parent Relief (2 parents, staying together)	$18,000
Grandparent Caregiver Relief	$3,000
NSman Wife Relief	$750
Total before cap	$85,750

Sarah’s reliefs are capped at $80,000. Her chargeable income falls to $20,000, and she pays no income tax at all, without contributing a single dollar to SRS or CPF top-ups.

The 2024 WMCR change means fewer mothers will hit the cap

Here is what has changed, and few articles mention it.

If Sarah’s two children had instead been born on or after 1 January 2024, her WMCR would be a fixed $18,000 rather than $35,000. Her total reliefs would reach only $68,750, her chargeable income would be $31,250, and she would pay about $244 in tax.

In other words, a working mother earning $100,000 with two children born after 1 January 2024 receives $17,000 less in Working Mother’s Child Relief than one whose children were born before 2024, based on the rates published by IRAS as of YA2026.

The cap still exists, but far fewer mothers of younger children will reach it. For most families going forward, the practical ceiling is how many reliefs you genuinely qualify for, not the $80,000 limit.

Should you still contribute to SRS after hitting the cap?

No. Once your reliefs reach $80,000, further SRS contributions earn no tax benefit at all, while the money still gets locked up under the same withdrawal rules as relief 3, but now with no tax saving in exchange.

If you are near the cap, a better move is to share shareable reliefs with your spouse. The Qualifying Child Relief, for instance, can be split in any proportion, so the parent further from the cap should claim more of it.

Worked Example: How Much Can You Actually Save?

Let’s put the pieces together for a typical profile.

Marcus is 35 and earns $72,000 a year ($6,000 a month, slightly above the median salary in Singapore). His automatic reliefs are CPF Relief of $14,400 and Earned Income Relief of $1,000, leaving a chargeable income of $56,600 and a tax bill of $1,712.

Before 31 December, Marcus makes three moves:

Action	Cash outlay	Relief/deduction
SRS contribution	$10,000	$10,000
CPF cash top-up (own Special Account)	$8,000	$8,000
Donation to an approved charity	$500	$1,250

His chargeable income falls to $37,350, and his tax bill drops to about $457.

That is $1,255 in tax saved, a 73% reduction. Worth being clear about what actually happened, though. Marcus did not get $1,255 for nothing. He moved $18,000 of his own money into accounts he cannot touch for decades, and gave $500 away.

That is true of nearly every relief in this guide. They exist to encourage saving for retirement, raising children, supporting parents, and giving. The tax saving comes after the decision, so make the decision on its own merits first.

Final Thoughts

Most reliefs in Singapore are claimed automatically or with a few clicks during e-filing in March and April. The ones that need planning, SRS contributions, CPF top-ups, and donations, close on 31 December each year.

Which means the useful thing to do now is check what you already qualify for, then decide well before December whether the voluntary ones fit your cash flow and your retirement plans.

And if you would like help working out how tax reliefs, CPF, SRS, and insurance fit together in your overall finances, that is exactly what a comprehensive financial planning session is for.
