Your first IRAS tax filing in Singapore

Singapore's income tax really is low. That part of the reputation is earned. What catches people out is everything around the rate. Whether you count as a tax resident at all. How little you get to deduct once you're here. And the fact that the bill arrives in one piece after the year has ended, with nothing taken off your pay along the way.

Most people who move here come from somewhere that taxes them harder, and they misread Singapore in both directions at once. They expect the low rate, which is real. They also expect the reliefs and deductions they had at home, which mostly aren't. This is the tax half of the move in detail. For the whole journey in order, the job, the pass, the lease and the rest, start with our complete guide to moving to Singapore, then come back here. Every figure below comes from the tax authority's own pages.

The two things newcomers get wrong

The first mistake is assuming the low rate applies to you automatically. It applies to tax residents. If you land late in the year, or leave sooner than planned, you can spend a year being taxed as a non-resident, which is a very different arithmetic.

The second mistake runs the other way. People arrive braced for high tax and quietly relieved, then go looking for the familiar reductions: pension contributions, mortgage interest, health cover, commuting, professional subscriptions. Those aren't here. The reliefs that do real work in a Singapore tax return are built around the national retirement scheme and National Service, and a foreigner on a work pass has neither. So your chargeable income sits much closer to your gross pay than you're used to.

Net of both misreadings, most arrivals still pay less than they did at home. But the shape of the year is different, and that shape is what this guide is really about.

Tax residency and the 183-day rule

IRAS is the Inland Revenue Authority of Singapore, the tax office. The first question it answers about you is whether you're a tax resident, because that single answer sets your rate and decides whether you can claim anything.

Citizens and permanent residents normally living here are residents. As a foreigner, the main test is days. Stay or work in Singapore for at least 183 days in the previous calendar year and you're a tax resident for that Year of Assessment. There are two extra routes. Stay or work here continuously for three consecutive years and you're a resident for all three, even if the first and third years fall short of 183 days. And if your employment straddles two calendar years and your total stay across them reaches 183 days, you're treated as a resident for both.

Two details matter when you count. Weekends and public holidays count as days of employment. So do temporary absences like a holiday abroad, and absences incidental to the job, like a business trip. You don't lose your count by leaving the island for a fortnight.

If none of those tests fit, you're a non-resident for tax purposes that year.

Your pass is not your tax residency

Here's the bit that quietly bites people, and it's the reason the first year feels easier than it is.

Foreigners issued a work pass valid for at least a year are treated as tax residents from the start. That's why your first return usually goes through at resident rates without you thinking about it. But that status is provisional. IRAS reviews your residency at the point of tax clearance, when you stop working here, based on the ordinary rules. If your stay turned out to be less than 183 days, you're treated as a non-resident.

So a two-year pass tells you nothing final. Someone who arrives in September, gets a two-year pass, and resigns the following May can find their position reassessed. If you're on a contract that might end early, or you're weighing an exit, that's worth modelling before you hand in notice rather than after.

Tax clearance itself is your employer's job, not yours. It's triggered when a non-citizen employee stops working here, goes on an overseas posting, or plans to leave Singapore for more than three months. The employer then has to tell IRAS at least a month in advance, and hold back money owed to you until it's settled. It applies to all work pass holders. If you hold unexercised share options, you're treated as having made the gain at that point, so it lands in the same reckoning.

Resident against non-resident: what the difference costs

Resident rates are progressive and start at nothing. The first S$20,000 of chargeable income is taxed at 0%. From there the bands climb in steps, and the top rate is 24%, which only bites on income above S$1,000,000.

Two anchor points, straight from the published table, tell you more than the whole thing. On the first S$80,000 of chargeable income the tax comes to S$3,350. On the first S$160,000 it comes to S$13,950. That's roughly 4% and roughly 9%, on figures that would be taxed at a multiple of that in most of Europe.

Non-resident treatment is a different animal. Your employment income is taxed at a flat 15%, or at the resident progressive rates, whichever produces the higher tax. Director's fees, consultancy fees and most other income are taxed at 24%. And you can't claim personal reliefs at all.

There is one relief in the other direction. If you're a non-resident who exercised employment here for 60 days or fewer in a year, that short-term employment income is exempt from tax. It doesn't apply if you were paid as a company director, a public entertainer or a professional such as a consultant, trainer or speaker.

One thing to be clear about: chargeable income isn't your salary. It's what's left after allowable expenses, donations and personal reliefs come off. Which brings us to the part where Singapore gives back much less than you expect.

What Singapore taxes, and what it leaves alone

The rule is that income earned in or derived from Singapore is taxable. Your salary, bonus, director's fees and commissions, gains when you exercise share options, and rent if you let out a property here. Pensions and retirement benefits have their own treatment.

What's genuinely not taxed is where Singapore separates itself.

There's no capital gains tax. Gains from selling a property here are treated as capital, and profits from buying and selling shares or other financial instruments, digital tokens included, are generally viewed as personal investment. Lottery and betting winnings aren't taxed either. The caveat is trading in property. Buy and sell often, with a profit-seeking motive, and IRAS can treat those gains as income instead. It weighs how frequently you transact, why, how long you hold, and whether you could afford to hold longer.

Foreign income is the other pleasant surprise, and the one most often misunderstood. Overseas income received in Singapore, including money paid straight into a Singapore bank account, is generally not taxable, and you don't declare what isn't taxable. But the exceptions are real, and one of them is aimed squarely at people like you. Overseas income is taxable if:

• you receive it through a partnership based in Singapore;
• your overseas work is incidental to your Singapore employment;
• you have a trade here and carry on an overseas trade incidental to it;
• you work in Singapore for a foreign employer;
• or you're employed abroad on behalf of the Singapore Government.

Read that fourth one twice. Sitting in Singapore while a company abroad pays you is taxable here. Plenty of remote workers assume the opposite because the money never touches a local account, and it doesn't help them.

If the same income is taxed abroad too, there's double taxation relief to apply for, and Singapore has a wide network of treaties. That's the point at which the paperwork stops being a form-filling exercise.

The reliefs you're used to, and the ones you'll actually get

Only tax residents can claim personal reliefs. Non-residents get none. And there's an overall cap: the total of all reliefs claimed is capped at S$80,000 for each Year of Assessment.

That cap won't be your problem. The list will be. Most of the reliefs that matter here don't reach a foreigner on a work pass. Retirement scheme relief is only for citizens and permanent residents, which rules it out for you at a stroke. The National Service reliefs are the same story. There's no relief for rent, none for mortgage interest on your home, and nothing for the private health cover you're almost certainly paying for.

What you can realistically claim comes down to a short list:

• Earned Income Relief, granted automatically if you have taxable earned income. It's up to S$1,000 if you're under 55, S$6,000 from 55 to 59, and S$8,000 at 60 and above, and it's capped at your earned income if that's lower.
• Family reliefs, if you meet the conditions. Spouse Relief is S$2,000 where your spouse lived with or was supported by you and had annual income of no more than S$8,000. Child reliefs have their own tests.
• Life Insurance Relief, which is the one people miss. It only opens up when your contributions to the national retirement scheme were under S$5,000 in the year, which describes most work pass holders exactly. You claim the lower of the gap up to S$5,000 or a small percentage of the sum insured, and the insurer needs an office or branch in Singapore.

Compared with a European return, that's a thin list, and it's the honest reason your effective rate here still lands where it does. The rate is low because the base is broad.

Who has to file

You have to file for the previous calendar year if any of these is true:

• your total income was more than S$22,000;
• you had self-employment income with a net profit of more than S$6,000;
• or you're a non-resident who earned income from Singapore.

That last one has no floor under it. Non-residents file regardless of how little they earned.

Above all of that sits one rule that overrides the rest. If IRAS sends you a letter, a form or a text telling you to file, you file, whatever you earned and whatever your employer has already reported.

Plenty of people don't have to file at all, and won't know until they look. Log in to myTax Portal and it tells you which of three situations you're in. Either you're required to file. Or you're on the No-Filing Service, where the return is pre-filled and you only have to check it. Or you're on Direct Notice of Assessment, where the bill is prepared from records and you do nothing unless something looks wrong.

How the filing actually works

Tax here runs on a preceding-year basis. The Year of Assessment you file for covers the income you earned in the calendar year before it. So your first filing season is the spring after your first partial year here, and it will cover only the months you were actually working.

The mechanics are short:

1. Get your login. Everything runs through myTax Portal, and you get in with Singpass or, if you're not eligible for that, a Singpass Foreign user Account. Sort this out in your first weeks, not in April.
2. Check what your employer has sent. If they're in the Auto-Inclusion Scheme, they submit your income to IRAS by 1 March and it appears pre-filled. You don't declare it again. If they're not in the scheme, they should hand you a Form IR8A by 1 March and you enter the figures yourself.
3. File between 1 March and 18 April. That date is the same every year. Paper returns are due by the same date, though almost everyone files online.
4. If you need longer, you can ask for an extension of up to 14 days through myTax Portal. That option isn't available if you're on the No-Filing Service.
5. Keep your records for five years. Payslips, employer forms, receipts for anything you claimed. You don't send them in unless asked.

If you spot a mistake after filing, you can re-file once, and that has to be done by 18 April as well. After the tax bill arrives, corrections go through the Amend Tax Bill service, within 30 days of the bill's date.

The bill, and paying it

This is the part that surprises people most, so plan for it before your first April.

Income tax isn't taken out of your monthly pay. Your employer reports what it paid you and IRAS bills you afterwards, in a document called the Notice of Assessment. Your take-home looks generous all year, and then a year's tax arrives as one number.

It's payable within one month from the date of the bill. You can pay by direct debit, at a payment kiosk or through internet banking. If you disagree with the assessment you still have to pay by the due date while you argue it, and any overpayment gets refunded. Check the bill properly when it comes, because it's your responsibility that the income and the relief claims on it are right.

Missing the filing date is treated as an offence, not an oversight. IRAS can raise an estimated assessment based on old years and other information, and that estimate is payable within a month even if you object. It can also offer to settle the matter for a composition sum, up to S$5,000 per offence depending on your record, or issue a summons, with a fine of up to S$5,000 on conviction. If you did file late, appeals for a waiver are considered once the outstanding return is actually in.

Your first filing year, in order

1. In your first month, set up Singpass or a Singpass Foreign user Account. You cannot file without one, and it gates most other government services too.
2. Count your days. Note your arrival date and work out where you land against 183 days for the calendar year. It decides your rate.
3. Ask your employer one question: are they in the Auto-Inclusion Scheme? The answer tells you whether your income turns up pre-filled or whether you'll be typing it in from a form.
4. Put money aside monthly. Nothing is deducted at source, so the whole year's tax lands at once. Setting aside a rough share of pay each month turns a shock into an admin task.
5. Diary 18 April, and check myTax Portal from 1 March to see whether you're required to file, pre-filled, or on the direct assessment route.
6. Keep the foreign paperwork. If you earned anywhere else in the same calendar year, keep those statements. The overlap year is the one that gets complicated.

When it's worth paying someone

For a straightforward year, one employer, one country, nothing else going on, this is a half-hour job online and you don't need help.

It's worth getting advice when your year has a seam in it. A first year that spans two countries. A departure that might flip your residency at tax clearance. Income from a foreign employer while you're sitting here, rental property abroad, share options vesting, or a treaty claim to make. Those are the cases where an hour with someone who does this daily costs less than the mistake. If you'd rather have a person read it with you, you can compare English-speaking tax advisers and accountants in Singapore on Locallista.

Every business listed is screened before it goes up and reviews are phone-verified, so the ranking reflects real expat experience rather than who paid the most. It's free to browse and free to get in touch. If you're still building the wider budget this all sits inside, our piece on what it really costs to live in Singapore covers the rest of the month.

Frequently asked questions

Do I still have to file if my employer already sends my salary to IRAS?

Sometimes yes. If your employer is in the Auto-Inclusion Scheme, your pay is pre-filled and you don't declare it again. You still have to file if IRAS sends you a letter, form or text telling you to, or if you have other income to report, or if you want to claim reliefs. Log in to myTax Portal and it tells you which group you're in.

My work pass is valid for two years, so am I automatically a tax resident?

Not permanently. A work pass valid for at least a year gets you treated as a resident from the start, which is why your first year usually feels straightforward. That status is reviewed when you leave the job, at what IRAS calls tax clearance. If your actual stay here fell short of the day count, you can be reassessed as a non-resident for that year.

Is the income I still earn back home taxed in Singapore?

Usually not. Overseas income received in Singapore, including money paid into a Singapore bank account, is generally not taxable for individuals. There are real exceptions, though. The one that catches people is working here for a foreign employer, which is taxable. Income received through a partnership based here, and overseas work that is incidental to your Singapore job, are also caught.

Do I pay tax when I sell shares or a property?

Generally no. Singapore does not tax capital gains, so profits from selling a property, shares or other financial instruments are usually treated as personal investment gains and left alone. The exception is trading. If you buy and sell property with a profit-seeking motive, IRAS can treat those gains as taxable income and looks at things like how often you deal and how long you hold.

What happens if I miss the filing date?

Missing it is an offence rather than a slap on the wrist. IRAS can estimate your income and issue an assessment anyway, and you have to pay that estimate within a month even while you dispute it. It can also offer to settle the offence for a fixed sum, or send you a court summons. File late rather than not at all, and appeal for a waiver once the return is in.

Can I claim anything for my rent, my mortgage back home or my pension?

No. There is no relief for rent or for mortgage interest on your home, and the retirement reliefs are tied to the national scheme that work pass holders don't pay into. What you can claim is a small automatic relief for having earned income, plus family reliefs if you meet the conditions. Life insurance relief is the one worth checking, because it only opens up for people with little or no contribution to the national scheme.
