If you have only recently arrived, or you work in Singapore for part of the year and live elsewhere, one of the first things worth understanding is how non-resident tax Singapore rules apply to you. Your tax status here is not about your passport or your visa. It is decided by how much time you spend in the country and the nature of your work. Getting this right matters, because residents and non-residents are taxed on very different bases, and the gap in what you pay can be significant.
This article is general information, not personalised financial, tax or legal advice. Tax rules and rates change, so confirm the current figures with IRAS before making any decisions.
Who Counts as a Non-Resident
IRAS treats you as a tax resident for a Year of Assessment if you are a Singapore citizen or Permanent Resident who normally lives here, or if you are a foreigner who stayed or worked in Singapore for a qualifying number of days in the year. The widely cited benchmark is the 183-day test: broadly, if your stay or employment reaches that threshold in the relevant period, you are generally assessed as a resident.
If you fall short of that threshold, you are usually assessed as a non-resident. This commonly affects short-term assignees, people who split the year between countries, and those who arrive late in the calendar year. Because the counting rules and any concessions for stays spanning two years can be intricate, check how your own days are counted with IRAS rather than assuming.
How Non-Residents Are Taxed on Employment Income
The headline difference is that non-residents do not receive the personal reliefs and the progressive resident rates that residents enjoy. Employment income earned by a non-resident is taxed under its own rules, and IRAS generally applies a flat rate or the resident rates, whichever produces the higher tax, so there is no advantage in claiming non-resident status to lower an employment bill.
There is one narrow situation many newcomers ask about. Short-term employment in Singapore that falls under a very brief threshold within a calendar year may be exempt, but this exemption is limited and does not apply to everyone, such as company directors and certain professionals. Do not assume you qualify. Confirm the current threshold and the exclusions with IRAS, because the details matter and the exemption is easy to misread.
Director Fees, Consultancy and Other Income
Non-residents often earn money in Singapore that is not ordinary salary, and these are handled differently again:
- Director fees paid to a non-resident director are taxed at a specific rate set for such payments.
- Professional and consultancy income earned by a non-resident, for example a visiting speaker or a foreign expert, is typically subject to withholding tax deducted by the payer before you receive it.
- Other income such as certain royalties or interest paid to non-residents may also fall under withholding tax rules.
Withholding tax means the paying company in Singapore holds back a portion and remits it to IRAS on your behalf, so you may receive the net amount. The applicable rates differ by income type and can be affected by tax treaties between Singapore and your home country. Always confirm the current withholding rate and whether a treaty applies before you sign a contract, since it changes what actually lands in your account.
Resident Versus Non-Resident at a Glance
The table below summarises the practical differences. Treat it as a map of the concepts, not a source of exact rates, which you should verify with IRAS.
| Feature | Tax resident | Non-resident |
|---|---|---|
| Basis of the day count | Meets the qualifying stay in the year | Falls short of the qualifying stay |
| Personal reliefs | Available if you qualify | Generally not available |
| Employment income | Progressive resident rates | Flat rate or resident rates, whichever is higher |
| Director fees and consultancy | Assessed as resident income | Specific rate or withholding tax applies |
The key takeaway is that resident status usually comes with reliefs and a graduated scale that benefits most ordinary earners, while non-resident treatment is flatter and stricter. That is why your day count is worth tracking carefully across the year.
Filing, Withholding and Staying Compliant
How you settle your Singapore tax depends on the type of income. Where withholding tax applies, the payer handles the deduction and you may not need to do anything further for that income, though you should keep the documentation. For employment income that is not withheld at source, you may still need to file, and your employer may participate in schemes that report or handle tax for departing foreign staff.
A few habits keep you out of trouble:
- Track the exact dates you enter and leave Singapore, since your status hinges on the day count.
- Keep contracts, payslips and any withholding statements, because they prove what was deducted and why.
- Check whether a tax treaty between Singapore and your home country changes your position, as it can reduce or reallocate the tax.
- Settle any tax due before you leave the country for good, because tax clearance can be required for departing employees.
If your income mixes several categories, or you are moving between resident and non-resident status across years, professional advice is money well spent. The rules are not designed to trap you, but they are precise, and small timing differences can change your bill. When in doubt, confirm the current position with IRAS or a qualified tax adviser.

Frequently Asked Questions
Do non-residents need to file an income tax return in Singapore? Often yes, if they have employment or other income that is not fully covered by withholding tax. Where withholding has been applied correctly, a separate return may not be needed for that income. Check with IRAS, since the requirement depends on your income types.
What is tax clearance when a foreign employee leaves Singapore? Employers must notify IRAS when a foreign employee stops working or leaves, and may need to withhold money owed to them until the tax is settled. This is often called tax clearance, and it ensures any tax due is paid before final departure.
Do business trips abroad count against the 183-day test? The count is based on days you are physically present or employed in Singapore, and short trips abroad can affect it depending on how IRAS treats your employment pattern. Keep travel records and confirm how your specific days are counted with IRAS.
How are non-resident landlords taxed on Singapore rental income? Rental income from Singapore property is taxable here even if the owner lives abroad, and non-residents are taxed on it at the non-resident rate without personal reliefs. Allowable expenses can still reduce the net rent, so keep records and check current rates with IRAS.
Can I claim back withholding tax deducted from my consultancy fees? In some cases non-residents can elect to be taxed on net income instead of the gross amount withheld, which may lead to a refund if expenses were significant. Whether this helps depends on your costs and the rules in force, so ask IRAS or a tax adviser.
