First Year Tax Singapore Expat: How a Partial Year Is Taxed if You Arrive October to December

Short answer: First year tax Singapore expat rules are tricky if you arrive between October and December, because you will have fewer than 183 days in the arrival year. IRAS’s two-year and three-year administrative concessions can still make you a tax resident for that year, depending on how long you stay and work here.

First year tax Singapore expat: how is a partial year taxed if you arrive in October to December?

You are taxed in Singapore only on income earned here, and your residency status for the arrival year depends on days in Singapore, not on your pass. A late-year arrival usually has a short first calendar year, so the concessions matter far more than the plain 183-day test.

IRAS assesses income on a preceding year basis. Income earned from 1 January to 31 December 2026 is taxed in YA 2027, and your first tax return for that income is filed in 2027. If you land on 15 October 2026, your 2026 income is only the pay you earn from the start of your Singapore employment to 31 December, but the tax rate applied to it can be very different depending on whether IRAS treats you as a resident or a non-resident.

This guide covers the first partial year. For the general 183-day rule, read our Singapore tax residency and 183-day rule guide. For proof of residency to a foreign tax authority, see our post on the certificate of residence for individuals, which we do not repeat here.

What are the basic tax residency rules for foreigners?

A foreigner is a tax resident for a Year of Assessment if they stayed or worked in Singapore for at least 183 days in the previous calendar year, or qualify under the two-year or three-year administrative concession. Anyone who meets none of these is a non-resident.

Per IRAS (as at 7 November 2026), the test counts days of stay and work, including weekends and public holidays. Temporary absences such as overseas vacation leave, and absences incidental to your employment such as business trips, still count towards your days in Singapore.

IRAS also states that foreigners issued with a work pass valid for at least one year are treated as tax residents. That status is reviewed at tax clearance when you cease employment, and if your stay turns out to be less than 183 days, you are regarded as a non-resident. The practical point for a late-year arrival: treat resident status as provisional until you know how long you will stay. Our guide to IR21 tax clearance for departing foreign employees explains the review at exit.

The 183-day test alone is hard to meet in a short first year. Counting from 1 July 2026, a person present every day to 31 December 2026 reaches 184 days. Anyone arriving after 2 July 2026 falls short for 2026 on days alone.

What is the two-year administrative concession?

The two-year concession treats you as a tax resident for both calendar years if your employment straddles two calendar years and your total stay across them is at least 183 days. It applies to foreign employees, and excludes company directors, public entertainers and professionals.

IRAS says the employment period plus your physical presence immediately before and after your employment must cover a continuous period of at least 183 days. The concession applies to foreign employees who entered Singapore from 1 January 2007 (per IRAS).

IRAS gives an example that fits an October arrival. A person arrives on 3 November 2024, starts work on 6 November 2024, ceases employment on 5 May 2025 and leaves on 7 May 2025. Their stay is 59 days in 2024 and 127 days in 2025, a total of 186 days, so they are resident for YA 2025 and YA 2026.

IRAS also gives the contrast. A person who worked from 4 August 2024 to 29 December 2024 and stayed to 7 April 2025 is a non-resident for both years. Their employment did not straddle two calendar years, and each year was under 183 days.

If you are a director of a company, the two-year concession is not available to you on IRAS’s wording. Check your position with IRAS or a tax adviser before relying on it.

What is the three-year administrative concession?

If you stay or work in Singapore continuously across three consecutive calendar years, IRAS treats you as a tax resident for all three, even if you were here for fewer than 183 days in the first and third years. A late-year arrival who stays at least into the third calendar year benefits most.

IRAS’s own example runs from 3 November 2023 to 7 May 2025. That is 59 days in 2023, 366 days in 2024 and 127 days in 2025. The person is a tax resident for YA 2024, YA 2025 and YA 2026.

Applied to a 2026 arrival, staying continuously from late 2026 into 2028 would cover calendar years 2026, 2027 and 2028, so YA 2027 to YA 2029. This is our reading of the IRAS rule, not a figure IRAS publishes for 2026 arrivals.

How would these rules apply to someone arriving on 15 October 2026?

The outcome turns on how long you stay. The table below applies the IRAS tests to four stay lengths for a foreigner employee (not a director) arriving on 15 October 2026. The day counts are our calculations from IRAS’s rules; they are illustrations, not IRAS rulings.

Stay in Singapore (arrive 15 October 2026)	Days in 2026 / 2027	Rule that applies	Status
Leave 28 February 2027	78 / 59 (total 137)	Straddles two years but under 183 days in total	Non-resident for YA 2027 and YA 2028
Leave 30 June 2027	78 / 181 (total 259)	Two-year concession	Resident for YA 2027 and YA 2028
Leave 15 November 2027	78 / 319	Two-year concession for 2026; 183 days for 2027	Resident for YA 2027 and YA 2028
Stay continuously into 2028	Three calendar years	Three-year concession	Resident for YA 2027 to YA 2029

The first row is the trap. Leaving after about four and a half months straddles the new year but still falls under 183 days, so the concession does not help.

Does resident or non-resident status change how much tax I pay?

Yes, often by a large amount. Residents are taxed at progressive rates from 0% to 24% after reliefs. Non-residents pay the higher of a flat 15% or the resident rates on employment income, with no personal reliefs.

Per IRAS (as at 7 November 2026), the resident rates from YA 2024 onwards start with the first S$20,000 of chargeable income at 0%, then 2% on the next S$10,000, and rise in steps to 24% on income above S$1,000,000. Residents also receive tax-exempt treatment on most foreign-sourced income brought into Singapore, except income received through Singapore partnerships.

A simple illustration, before any reliefs: on S$100,000 of chargeable income, the resident rate table gives gross tax of S$5,650 (S$3,350 on the first S$80,000 plus 11.5% on the next S$20,000). A non-resident on S$100,000 of employment income pays at least 15%, which is S$15,000, and cannot claim personal reliefs. Actual figures depend on your income, reliefs and rebates.

Non-residents who work 60 days or fewer in a year may be exempt on employment income, but IRAS excludes directors, public entertainers and professionals from this, and the rule is unlikely to help someone relocating to work here. Our post on non-resident income tax in Singapore covers the 15% rate in more depth.

How do I file my first Singapore tax return, and what does my employer submit?

Your employer reports your 2026 earnings to IRAS by 1 March 2027, and you then file or verify your return on myTax Portal in the filing season. Foreigners log in with Singpass or a Singpass Foreign user Account.

1. Your employer prepares Form IR8A for 2026 income by 1 March 2027 (per IRAS, under section 68(2) of the Income Tax Act). Employers in the Auto-Inclusion Scheme submit electronically and the figures are pre-filled in your return.
2. The IR8A for a new arrival shows your date of commencement, because IRAS requires that field where employment commenced in the year. Check it matches your actual start date.
3. From March 2027, check myTax Portal. IRAS filing for Tax Season 2026 ran from 1 March to 18 April 2026. Confirm the 2027 dates with IRAS when they are published.
4. File your return, or if you are under the No-Filing Service, verify the pre-filled details by the deadline.
5. If your tax bill shows errors, use the Amend Tax Bill service within 30 days of the bill date.

Generally, IRAS requires a return where total income in the preceding calendar year is more than S$22,000, or where a non-resident derived income from Singapore that is not subject to withholding tax. You must file whenever IRAS notifies you. An extension of up to 14 days may be granted on request. For the difference between IR8A and IR21, see our IR8A vs IR21 guide.

Are relocation allowances and reimbursements taxed in my first year?

Cash relocation allowances are taxable in full, whether or not you spent them. Reimbursements of genuine moving costs are usually not taxed. This affects your first-year income figure, so ask your employer how each item is reported.

Per IRAS (as at 7 November 2026), you may deduct relocation expenses you actually incurred, such as airfare for you, your family and pets, freight and storage for personal belongings, temporary accommodation before starting work, and initial settling-in costs. If you claim less than the allowance, the excess is taxable. Personal items such as meals, laundry and transport are not deductible. Leave passages provided when a foreigner takes up a first appointment in Singapore are not taxable.

Frequently asked questions

If I arrive in December, am I a tax resident for that year?

Not on the 183-day test, because a December arrival has only a few weeks in the year. You may become resident for 2026 under the two-year concession if your employment runs into 2027 and your combined stay is at least 183 days, or under the three-year concession if you stay continuously into 2028.

Does having a work pass valid for a year make me a tax resident?

IRAS treats foreigners with a work pass valid for at least one year as tax residents, but reviews this when you cease employment at tax clearance. If your stay is under 183 days and no concession applies, you are regarded as a non-resident.

Do days I spend travelling for work count?

Yes. IRAS says temporary absences, such as overseas leave, and absences incidental to your employment, such as business trips, still count in your days in Singapore for residency purposes.

Can a company director use the two-year concession?

IRAS’s two-year concession excludes company directors, public entertainers and professionals. If you are a director, speak to IRAS or a tax adviser about your status.

Do I need to file a tax return in my first year?

Generally you must file if your total income in the preceding calendar year exceeded S$22,000, or if IRAS tells you to, and non-residents with income not subject to withholding tax must file. Your 2026 income is filed in 2027. Check myTax Portal from March 2027.

What if I leave Singapore after a few months?

IRAS reviews your tax residency status at tax clearance when you cease employment, and if your stay is under 183 days you are regarded as a non-resident. See our IR21 tax clearance guide.
