Bonus After Leaving Singapore: How IRAS Taxes It and What the IR21 Must Show
Short answer: A bonus after leaving Singapore is still taxable if it rewards work done under your Singapore employment. The tax year depends on whether the bonus is contractual or non-contractual. Your employer must withhold it, and declare it to IRAS through the Form IR21 or an Additional Form IR21, before paying you.
Key facts at a glance
- Bonus is listed as taxable employment income under section 10(2)(a) of the Income Tax Act 1947 (checked on Singapore Statutes Online on 9 November 2026).
- Contractual bonus: taxed in the year you become entitled to it, usually the year you did the work, even if it is paid later (IRAS, as at 9 November 2026).
- Non-contractual bonus: generally taxed on the date it is paid (IRAS, as at 9 November 2026).
- Employers must file the Form IR21 at least one month before a non-citizen employee ceases employment or leaves Singapore for more than three months, and withhold all monies due, including bonuses.
- Income paid after the year of cessation, such as a non-contractual bonus, goes in an Additional Form IR21, not in the next year’s IR8A or AIS submission.
- Filing late or not at all can lead to a fine of up to S$5,000 (IRAS, as at 9 November 2026).
- Typical IRAS processing: within 7 working days for e-filing, within 21 days for paper filing.

How is a bonus after leaving Singapore taxed by IRAS?
If the bonus is for work you did in Singapore, IRAS treats it as employment income, whether you receive it before or after you leave. The Income Tax Act 1947 charges tax on income derived from Singapore (section 10(1)(b)), and its definition of employment income expressly lists “bonus” (section 10(2)(a)).
Where the money lands does not change the answer. For people who work wholly overseas, IRAS says it “does not matter where and how you are being paid” when deciding Singapore tax. Check with IRAS if your bonus covers a mix of Singapore and overseas work.
Terms used in this article: a “bonus” is a payment on top of salary linked to performance or service. “Cessation” means the official last day of service. The “Form IR21” is the tax clearance form employers file for departing foreign and Singapore Permanent Resident employees. “IR8A” is the annual employment income return employers file for staff generally.
Which tax year does a bonus paid after I leave fall into?
It depends on whether the bonus is contractual or non-contractual. IRAS says a contractual bonus is taxed in the year you become entitled to it, while a non-contractual bonus is generally taxed on the date it is paid.
A contractual bonus is paid under the terms of your contract of service and cannot be withdrawn by the employer without legal consequences. IRAS gives the 13th month payment or annual wage supplement, and bonuses under a deferred or retention bonus plan, as examples. A non-contractual bonus can be withdrawn or cancelled by the employer before payment without legal consequences.
| Type of bonus | When IRAS taxes it | IRAS example |
|---|---|---|
| Contractual bonus | The year you are entitled to it under the contract or plan, usually the year you rendered the service | 13th month bonus for the year ended 31 December 2025, paid in February 2026: taxable in Year of Assessment 2026 |
| Contractual bonus with a future condition (for example, you must still be employed on the payment date) | The year the condition is met | Bonus paid 31 March 2025 only to staff who had not resigned by then: taxable in Year of Assessment 2026 for those who met both conditions |
| Bonus paid in advance, subject to conditions | The date of payment. If you later refund it, the refund adjusts your income in the year of refund | Inducement bonus paid 1 January 2024, 50 percent returned in 2025: taxed in 2024, with the refund deducted in 2025 |
| Discretionary bonus that later becomes legally binding | The year the employer binds itself to pay and you become entitled | Employer commits on 31 January 2025 to pay a 2024 bonus: taxed as 2025 income, even if paid in January 2026 |
| Non-contractual bonus | Generally the date it is paid | Bonus announced 1 December 2024 and paid 1 February 2025: taxable in Year of Assessment 2026 |
Source: IRAS, “Salary, bonus, director’s fee, commission and others”, as at 9 November 2026. The Year of Assessment is the year after the income year, so income earned in 2026 is assessed in Year of Assessment 2027.
Mere payment timing therefore does not decide a contractual bonus. If you resign in December 2026 and your 2026 contractual bonus is paid in March 2027, it is still 2026 income, unless a condition such as being employed on the payment date is not met.
MOM adds that bonuses and other variable payments are not compulsory unless they are in your contract. Read the bonus clause before assuming you are owed one, and see our guide on the 13th month bonus, AWS, CPF and tax.
What must my employer do about my bonus before I leave?
Your employer must tell IRAS through the Form IR21 and withhold all monies due to you, bonus included, from the day they know you are leaving. IRAS says this applies to non-citizen employees, including all work pass holders and Personalised Employment Pass holders.
- Filing deadline: at least one month before you cease employment, start an overseas posting, or leave Singapore for more than three months.
- Withholding: all monies due, such as overtime, leave pay, allowances, reimbursements, gratuities, lump sums and bonuses, from the date the employer is aware of your impending cessation or departure.
- If the employer cannot give one month’s notice or cannot withhold, the reason goes into the IR21. A 10-day grace period is generally granted for filing, per IRAS FAQs.
- Resignation: IRAS says withholding starts at the point of resignation, whatever the notice period.
The Employment Act does not let an employer deduct part of your monthly salary to build up a tax clearance pot, so withholding applies to sums due, not to ordinary monthly pay. For the wider pass side of leaving, see our guide to IR21 tax clearance for departing foreign employees.
How does the IR21 show a bonus that is paid later?
The IR21 shows income by calendar year. A contractual bonus for service up to your last day belongs in the IR21 income for that year. A non-contractual bonus paid after the year of cessation goes in an Additional Form IR21.
IRAS’s explanatory notes say a non-contractual bonus counts as income on the date it was paid, and if there is more than one payment in a year, the form asks for the date of the last payment.
- File the original IR21 at least one month before cessation. Report income for the year of cessation and, if it was not already sent through the Auto-Inclusion Scheme (AIS), the preceding year.
- Withhold all monies due, including any bonus you owe or may owe.
- If the income details change before clearance, for example a bonus is confirmed for the cessation year, file an Amended Form IR21. It must carry the full set of income details and supersedes earlier IR21 filings.
- If a bonus is paid or becomes payable after the year of cessation, e-file an Additional Form IR21 by choosing “Report income payable or paid to the employee after year of cessation”. IRAS gives a non-contractual bonus as the example.
- Keep withholding the additional amount until IRAS processes the Additional Form IR21, then act on the clearance directive.
- Do not also report the same income through the IR8A or AIS the next year.
Paper filers tick “Additional” and report only the additional income and additional withheld monies, because repeating income already reported means it is doubly assessed (IRAS).
The IRAS pages we reviewed on 9 November 2026 do not set out a method for estimating a bonus that has not yet been decided. If the amount is uncertain at filing, ask IRAS through myTax Mail before filing, rather than guessing.
What happens if my employer pays the bonus without filing or withholding?
The employer risks a fine of up to S$5,000, and may become liable for the tax you owe. IRAS says failing to file the IR21 by the due date is an offence, and it can offer to compound the offence or summon the employer to court.
| Employer lapse | IRAS consequence (as at 9 November 2026) |
|---|---|
| Not filing, or filing late, without a valid reason | Fine of up to S$5,000; composition of up to S$5,000 per offence may be offered based on compliance history |
| Unable to withhold monies and no reason given in the IR21 | Employer may be liable for the tax owed by the employee |
| Paying additional income before the Additional IR21 is processed | IRAS requires the additional income to be withheld pending processing |
For the employee, a late bonus is delayed rather than lost. After clearance, IRAS issues the employer either a Directive to Pay Tax or a Notification to Release Monies. The directive is posted within five to seven working days and an electronic copy appears in myTax Portal within three working days of processing.
How is a former employee’s bonus taxed if they live abroad?
Singapore tax rates depend on your residency, not on where you now live. IRAS says that if you render services in Singapore during overseas employment, 183 days or more in a calendar year makes you a tax resident taxed at progressive resident rates after reliefs.
For 61 to 182 days, IRAS treats you as a non-resident, taxed at a flat 15 percent with no personal reliefs, or at progressive resident rates, whichever gives the higher tax. These bands are given on IRAS’s page for overseas employment that includes Singapore duties, so confirm how they apply to your own year with IRAS. Our guide to Singapore non-resident income tax explains the 15 percent rate.
Can I be taxed twice on a bonus after leaving Singapore?
Possibly, but double tax treaties and your home country’s rules may give relief. IRAS says Avoidance of Double Taxation Agreements (DTAs) can protect you from being taxed twice, depending on the agreement’s wording.
Whether your new country taxes the same bonus, and whether it gives a credit for Singapore tax, is for that country’s tax authority to decide. IRAS says a Singapore tax resident can use a Certificate of Residence to claim DTA benefits abroad. See our guide to the Certificate of Residence for individuals. Keep the payslip, bonus letter and IRAS directive in case another tax office asks for proof.
What about retention bonuses, share awards and severance?
Each is treated differently from an ordinary performance bonus. IRAS lists retention bonuses, and bonuses with conditions of stay, as conditional payments, taxable when paid, with refunds adjusting income in the year of refund.
- Share options and unvested share awards: under the “deemed exercise” rule, IRAS taxes a gain at the point of tax clearance. Read our deemed exercise guide.
- Compensation for loss of office: generally not taxable as a capital receipt, according to IRAS, but salary in lieu of notice and gratuity for past services are taxable. See retrenchment benefits and tax.
Frequently asked questions
Is a bonus I receive after resigning from a Singapore job taxable?
Yes, if it rewards work under your Singapore employment. IRAS taxes bonuses as employment income, with the year set by whether the bonus is contractual or non-contractual.
Does my employer have to withhold my bonus when I resign?
If you are a non-citizen employee for whom tax clearance is required, yes. IRAS says employers must withhold all monies due, including bonuses, from the date they know you are leaving, and file the Form IR21 at least one month before you cease employment.
Will a bonus paid after I leave appear on my IR8A?
Generally not. IRAS says income covered by a filed IR21 is not reported through the IR8A or AIS, and further income payable after clearance goes in an Additional or Amended IR21.
Does a Singapore PR have to go through IR21 too?
Not always. IRAS says an SPR who is not leaving Singapore permanently can give the employer a Letter of Undertaking instead, but this does not apply to an overseas posting. If the SPR leaves permanently, tax clearance is required.
How long does IRAS take to clear the IR21?
IRAS says e-filed forms are typically processed within 7 working days and paper forms within 21 days, though incomplete information can take longer. Check with IRAS if your case is unusual.
