1. Do you need to file your income tax in 2025?

The simplest way to check if you need to file your income tax is to use IRAS’ Filing checker service.

But if you received a notification that you’re eligible for the No-Filing Service (NFS), let’s save you time: you do not need to file your income tax.

If you’re under the NFS, your tax details are already automatically entered. All you need to do is log in to verify that the information is accurate. The system may not capture all your tax reliefs or all of your additional income. Considering there are over 1.9 million taxpayers eligible for the NFS, it’s quite likely that you fall under this category of taxpayer.

You might also be on the Direct Notice of Assessment (D-NOA) initiative, in which case IRAS sends you your tax bills directly based on your income provided by your employer and the previous year’s relief claims. In this case, you still need to check that the information is accurate and make amendments if necessary.

Don’t fret if you need to make changes, you can file an amendment using the Amend Tax Bill digital service in myTax Portal within 30 days from the date of your tax bill.

When you need to file your income tax

You need to file your income tax if you answer “yes” to one or more of these questions:

1. Did you earn more than $22,000 (including gross rental) in 2024?
2. Do you have self-employment income with a net profit of more than $6,000?
3. Are you a non-Singapore resident who earned income from Singapore?

2. Tax changes announced for YA2025 and after

ICYMI, there’ve been a good number of tax changes in Singapore as of YA2025. These affect both individuals and companies. You can read all about the tax changes in more detail, but for now here’s a summary of the coming updates that affect individuals:

Personal Income Tax Rebate for YA2025	As part of the SG60 package, a rebate of 60% of tax payable is granted to all tax resident individuals for YA2025, capped at $200 per taxpayer.
No more tax relief for certain MediSave top-ups starting 2026	Starting 1 Jan 2026, you won’t get CPF Cash Top-Up tax relief if your cash top-up triggers a matching grant from the government under the Matched MediSave Scheme (MMSS).This is because the government is already giving a generous matching grant under MMSS, they’ve decided that you shouldn’t also get tax relief on top of that—just like how the rules already work for retirement account top-ups under the MRSS. You can still claim up to $16,000 in CPF Cash Top-Up Relief each year—$8,000 for yourself, and $8,000 for your loved ones—as long as the top-ups don’t trigger MMSS or MRSS matching grants.
Course Fees Relief to lapse from YA2026	This will be lapsed from YA2026, after which, individuals can continue to receive support for upskilling, reskilling, and career transitions through other existing government initiatives, such as SkillsFuture and Career Conversion Programmes.

3. Step 1. Log into IRAS Tax Portal

First things first: Kickstart the e-filing process by logging on to IRAS’ myTaxPortal. Have your Singpass on hand, because you’ll need to use that to log in after you select Personal Tax.

Tip: We like the Singpass mobile app for its convenience. The Singpass mobile app is much easier than trying to remember or password or jumping through all the 2FA hoops (yes, we’ve been there).

Once you’ve set up the app, just follow the onscreen instructions on the IRAS myTaxPortal to quickly enter the system. This usually means scanning the QR code if you’re doing your e-Filing via your computer (we prefer this, the screen is larger). It’s slightly different via your mobile phone (you’ll be clicking instead).

4. Step 2. Check your total income for YA2025

All logged in? Good. Next, click on Individuals > Filing Matters > File Income Tax Return on the top menu bar.

You should then see this: Income, Deductions and Reliefs Statement (IDRS) for the year ended 31 Dec 2024.

On this page, you can view your Total Employment Income earned in 2024 if you are a full-time, salaried employee. You will be seeing sources of income from different employers if you changed jobs part-way in 2024. Something missing? There’s also a link to click so you can check if your employer submitted your employment income information to IRAS.

Next, you’ll see your total donations and your total personal reliefs (this includes CPF contributions). If you made voluntary CPF contributions to your own or a loved one’s CPF Account or put money into your Supplementary Retirement Scheme in 2024, that will be reflected here as well.

You will then see your estimated income tax payable. This is based on your income, deductions and reliefs but before any tax adjustments or Parenthood Tax Rebate entitlement.

For those who are self-employed, be it partially or fully, you’ll need to go the DIY route. Please follow this guide by IRAS to help you manually enter your income for YA2025.

5. Step 3. Declare any additional income

Renting out rooms or running an online business in addition to your full-time job? The income gained from these ventures has to be declared on your income tax form as well.

These include activities such as: 

1. Trade or business income: This includes virtual currency earnings, aka crypto.
2. Income from Government Grants: You might have received payouts from the Jobs Support Scheme, Special Employment Credit or similar.
3. Rental income
4. Dividends, gains, and interest: Most local stocks and REITs are exempted
5. Annuity payouts: It’s kinda like a salary
6. Alimony and maintenance payments
7. Estate or trust income

At the end of the page, you’ll see two options under the section: Next Step.

No, this is not a trick question or a Choose Your Own Adventure book. It simply asks if you want to preview your Notice of Assessment (if good to go) or Edit My Tax Form (if you need to make changes).

Go for the second option if you need to declare any extra income, amend or add/remove any personal reliefs.

6. Step 4. Check tax reliefs & deductions

We’re now looking at the Total Donations and Total Personal Reliefs section in more detail. We’re already in 2025, so rushing to give $5,000 to your favourite charity or plonking the full $15,300 into your SRS account won’t make your income tax amount go away for YA2025. Instead, whatever you do in 2025 will be reflected in your YA2026 tax bill.

So chill.

Anyway, as the name suggests, Total Donations and Total Personal Reliefs work to reduce the amount of tax payable. Your task right now is to check that your total donations and total personal reliefs you’ve amassed in 2024 are reflected accurately in your YA2025 NOA tax bill.

Here’s a list of some typical personal reliefs a Singapore taxpayer would have:

• Earned Income Relief: Anyone who has taxable income, a bit like a small subsidy on your tax.
• NSMan Relief: This can apply to self/wife/parent. Yep, the mothers and wives of our operationally-ready NS Men benefit too.
• Various CPF Reliefs: You enjoy income tax reliefs when you put money into CPF OA/SA/RA/MediSave, be it your own or your family members (Singaporeans and PRs only). Do note that there’s a cap for voluntary top-ups.
• Supplementary Retirement Scheme (SRS) Relief: There’s a cap of $15,300
• Handicapped Sibling/Parent/Grandparent Reliefs: If you’re supporting someone in your family, you also get tax relief. This extends to your parents-in-law and grandparents-in-law too.
• Course Fees Relief: They’ll need to fulfil certain criteria.
• Life Insurance Relief: Only if you’re paying for your life insurance premiums AND if you’ve contributed less than $5,000 in total to your CPF.

Note: The maximum income tax reliefs are capped at $80,000.

Something missing? Scroll down to the bottom of the page to Next Steps and choose Edit My Tax Form.

7. Step 5. It’s time to file

All good? Happy with the final amount and you’ve done all you can to claim all the reliefs? When everything has been amended and is now accurate, it’s time to preview your NOA and finally, Send My Tax Bill.

Remember to file your income tax from 1 Mar 2025 to 18 Apr 2025. If you miss the 18 Apr 2025 deadline, your tax form may be sent automatically, and/or you may incur penalties like a fine.

Here’s what the IRAS website says: “If you fail to file your tax returns for 2 years or more, you may be issued with a summons to attend Court. On conviction in Court, for each offence, you may be ordered to pay: A penalty that is twice the amount of tax assessed; and. A fine of up to $5,000.” Ouch.

8. Step 6. Check your Notice of Assessment

You will receive your income tax bill, also known as your Notice of Assessment, from the end of April 2025. This is a statement that tells you how much to pay for your income tax and when to do so. The NOA can be found in your myTax Portal.

The notification that your NOA is ready can be sent via SMS, email or both—you can change this in myTax Portal > Account > Profile > Update Notice Preferences.

Here’s another chance to put things right. If there’s anything inaccurate on your NOA, go to your myTax Portal and submit an Object to Assessment (top menu bar > Individuals > Filing Matters > Object to Assessment) within 30 days of receiving your NOA. Make sure you have the supporting evidence ready for IRAS’ review.

This can be a bit of a hassle, so it’s best to ensure everything is accurate on your first submission. For more details, check out IRAS’ guide on objecting to your NOA.

9. Step 7. Pay your income tax

Cash? Credit? Cashless? Overseas at the moment? Can’t leave home? Well, there are just so many ways to pay:

• GIRO (you can enjoy 12 interest-free monthly instalments with this option)
• PayNow QR (scan the code in myTax Portal)
• AXS: physical, website, mobile app
• SingPost: physical SAM Kiosk, in-person at SingPost branches, SAM Web, SingPost Mobile App
• Internet Banking Bill Payment: Various banks accepted
• Internet Banking Fund Transfer: Make sure you follow the instructions closely)

IRAS will even accept telegraphic transfers if you are overseas and unable to use any of the above payment methods.

10. Can I use my credit card to pay income tax?

IRAS says they don’t directly offer the option for credit card payments as they incur a high transaction cost. To preserve public funds (taxpayers’ money), they need to keep their cost of collection low.

However, there is a workaround. It depends on your credit card issuing bank, but you might be able to use your credit card to pay your income tax on the AXS e-Station (website) or via AXS m-Station (mobile app). There is, however, a payment limit of $9,999.99. 

Meanwhile, a few banks might also allow you to pay your income tax indirectly via tax payment facilities. You might incur a processing fee, but hey, it’s worth your air miles or your rewards points, yes?

Check out these options:

The Standard Chartered Visa Infinite Credit Card lets you pay your taxes with its credit card income tax payment facility, and you’ll earn 360° Rewards Points while you’re at it. You can then redeem the points you’ll earn for miles, cashback, or products.

Do note that there is a one-time processing fee of 1.9% on your tax payable amount.

With Citibank’s PayAll service, you can pay your taxes (yup, not just limited to income tax) with your Citi credit card. While there is a service fee of 2.6%, you’ll earn the base earn rate on your card. i.e. 1.2 miles per $1 on the Citi PremierMiles card.

Another bank, DBS, has an Income Tax Payment Plan. While there is 0% interest for up to 24 months, plans under My Preferred Payment Plan incur a low, one-time processing fee (based on transaction amount). The silver lining is that you can split your income tax bill over 12 months, but those holding certain credit cards such as the DBS Altitude Visa Signature Card can earn 1.3 miles per $1.

Sadly, the much-loved HSBC’s Tax Payment Programme was terminated on 1 Apr 2023. However, you can also consider using your UOB, Standard Chartered, and OCBC’s CardUp where you can earn miles when you pay bills that don’t usually earn rewards, which includes your income tax. For example, receive up to 1.6 VOYAGE Miles (1.3 for OCBC VOYAGE) with every $1 spent on your OCBC VOYAGE Card.

Tip: Only use your credit card to pay large income tax amounts to make the processing fees worthwhile. No point in incurring fees and earning only measly miles or rewards points for that effort.
