- Tax clearance is the employer’s filing, not the employee’s, and the unpaid tax becomes yours if you get it wrong.
- File Form IR21 at least one month before the employee’s last day, overseas posting, or departure from Singapore.
- Withhold every dollar owed from the day you learn they’re leaving, until IRAS issues a Clearance Directive.
- E-Filed forms are cleared in 7 working days; paper takes 21. Late filing risks a composition amount of up to S$5,000.
Tax clearance in Singapore is something you do for your employee, not something they do for themselves. When a foreign or Singapore Permanent Resident employee resigns, starts an overseas posting, or leaves the country for more than three months, you must notify IRAS at least one month ahead on Form IR21. Until IRAS replies, you hold back every dollar you still owe them.
Miss the deadline or release the money early, and their unpaid tax can become your bill. Most employers learn this the week someone resigns.
Just had a resignation letter land on your desk, with no idea whether the clock has already started?
What is tax clearance in Singapore, and why is it your job as the employer?
Tax clearance settles a departing non-citizen employee’s income tax before they stop working for you or leave the country. IRAS calls the filing Form IR21. You file it, withhold the money, and bear the liability if it goes wrong.
That last part catches people out. The tax is the employee’s, but the obligation is yours, because once someone boards a flight, IRAS has little leverage over them and plenty over you. It’s the same logic that makes payroll services in Singapore worth handing over: the admin is small, the exposure isn’t.
Three things happen in sequence, and they don’t overlap.
- Notify IRAS on Form IR21 at least one month before the employee’s last day.
- Withhold all monies due to them from the day you know they’re leaving.
- Wait for IRAS to issue a Clearance Directive, then either pay IRAS or release the money.
It covers every work pass holder, including Overseas Networks & Expertise Pass and Personalised Employment Pass holders. Seniority doesn’t buy an exemption.
Which employees need tax clearance, and who is exempt?
You need it for non-Singapore Citizen employees ceasing employment with you, going on an overseas posting, or leaving Singapore for more than three months. Singapore Citizens never need it. Everything else turns on the specifics.
Death in service is also a cessation, and rare enough to be worth a direct call to IRAS rather than a template answer.When you don’t need to file Form IR21
Beyond the scenarios above, IRAS waives clearance on four low-income thresholds. You still report the income on Form IR8A or through the Auto-Inclusion Scheme by 1 March of the following year.
- 60 days or less worked in a calendar year. Board directors, public entertainers, and professionals such as consultants, trainers, and coaches are excluded.
- 183 days or more in a calendar year, with annual income under S$21,000.
- 183 days or more across two calendar years, with income under S$21,000 in each. Covers only foreign employees who entered Singapore on or after 1 January 2007, and never directors, public entertainers, or people exercising a profession.
- Three continuous years or more, with income under S$21,000 in each year.
All four hold only if the employee hasn’t worked for another Singapore employer during the cessation year or the year before. If you can’t verify their history, e-File anyway. myTax Portal tells you on the spot whether clearance is needed.
What if you want to transfer the employee’s Employment Pass instead of ending it?
An internal transfer inside the same group usually doesn’t trigger tax clearance. A transfer between unrelated employers always does. The distinction is ownership, not the person’s job title or desk.
If the move is a merger, takeover, restructuring, or posting within the same group, you don’t file Form IR21. Instead:
- Notify IRAS through myTax Mail on myTax Portal.
- Set the “Nature of Enquiry” to “Tax Clearance/Form IR21” and attach IRAS’s Waiver of Tax Clearance template.
- Have both the former and the new employer report the income on Form IR8A by 1 March of the following year.
One trap sits inside this exemption. If the employee then leaves the new employer during the same transitional year, clearance is required after all, and it lands on the new entity.
The pass runs on a separate track. Employment Passes aren’t transferable, so the new entity applies for its own, and visas and hiring employees in Singapore rarely line up with the tax timeline.
When must you file Form IR21?
At least one month before the earliest of three events: the day the employee stops working for you in Singapore, the day they start an overseas posting, or the day they leave Singapore for more than three months.
The clock runs from the event, not from the resignation letter. Someone who resigns on 2 March with three months’ notice and a last day of 1 June gives you until 1 May. Someone who resigns on Friday and walks on Tuesday gives you nothing, which IRAS accepts as a valid reason if you say so in the form.
If you can’t give the full month, file anyway and put the reason in the form. Filing late with an explanation beats not filing at all. Tax clearance also runs alongside cancelling an employee’s work pass, which MOM expects within a week of the last day, so the two deadlines land in the same fortnight and get confused constantly.How much salary must you withhold, and when can you release it?
All of it, from the day you become aware the employee is leaving, until IRAS tells you otherwise.
“All monies” is broader than the final salary. IRAS lists overtime pay, leave pay, allowances, reimbursements, gratuities, and lump sum payments. Anything you’d otherwise pay after the trigger date gets held.
Two things get misunderstood, and both are worth heading off early.
- The money is the employee’s, not yours. You’re holding it, not keeping it. Saying so plainly at notice prevents most of the friction that follows.
- You can’t release early. If you’ve filed an Amended or Additional Form IR21, keep holding until the second Directive arrives, even if the first said release.
If payroll genuinely can’t withhold, say because the final run had already gone out, tell IRAS in the form and explain why. Stay silent, and you may be liable for the tax yourself.
How do you file Form IR21, and how does it relate to IR8A?
You file it on myTax Portal using Corppass, and it replaces IR8A for that employee in that year.
E-Filing clears in seven working days against 21 for paper. What the form needs:
- The employee’s income for the year of cessation.
- Their income for the preceding year, if that hasn’t already reached IRAS through the Auto-Inclusion Scheme.
- The amount of monies you’re withholding.
- A reason, if you’re filing on short notice or can’t withhold in full.
Income items that get misreported
Salary in lieu of notice is taxable. So is gratuity for past services payable at the end of a contract.
Severance that genuinely compensates for loss of office may not be, so assess each part of a retrenchment package separately. Unexercised share options and unvested share awards count as exercised at clearance under IRAS’s deemed exercise rule, including where selling restrictions apply.
The relationship with Form IR8A and employer income reporting is simple: file IR21, and you don’t file IR8A for that employee. IR8A is the annual return for people still on your payroll; IR21 is the exit return for people leaving it.
How long does IRAS take, and what do you do while you wait?
Seven working days for an e-Filed Form IR21, 21 days on paper, and nothing you do speeds it up. That’s the part clients most often ask us to accelerate. Your only lever is filing early and complete.
While you wait:
- Track the status on myTax Portal rather than emailing for updates.
- Leave the withheld monies exactly where they are.
- Tell the employee what’s happening and roughly when, so the silence doesn’t read as your delay.
- Watch for the Clearance Directive, posted within 5 to 7 working days and visible on myTax Portal within three working days.
The Directive comes in two forms. A Directive to Pay Tax tells you how much to remit to IRAS, due within 10 days of the Directive date. A Notification to Release Monies tells you to hand the withheld amount back to the employee.
TIPTip: File the moment the notice is given, not the moment payroll is calculated. Filing early costs nothing and buys back the entire IRAS processing window.
What are the penalties for filing late or releasing money early?
Two separate breaches, two separate consequences. Blending them is how employers underestimate the risk.
IRAS penalties for tax clearance failures| Breach | What IRAS can do | Exposure |
|---|---|---|
| Filing Form IR21 late, or not at all | Offer to compound the offence | Composition of up to S$5,000 per offence |
| Ignoring or refusing the composition offer | Summon the employer, including sole proprietors, partners, and directors, to Court | Fine of up to S$5,000 per offence on conviction |
| Not withholding monies you should have withheld | Hold you liable for the employee’s tax | The employee’s full tax bill |
| Paying the Directive amount late | Late payment penalty | 5% of the unpaid tax |
| Leaving the Directive unpaid beyond a month | Additional monthly penalty | 1% per completed month, capped at 12% |
| Continued non-payment | Appoint your bank, tenant, or lawyer as agent to recover the debt, or issue a Travel Restriction Order against sole proprietors and partners | Recovery plus penalties |
Waivers are narrow. A composition amount can be appealed on a first request, if clearance turned out not to be required, or if another group company already filed for that period. A late payment penalty can be appealed only once you’ve paid in full by the date on the notice, and only if you haven’t had a waiver in two calendar years.
These sit alongside the common penalties for Singapore companies most finance teams track. Tax clearance is the one that arrives without a calendar reminder.
Does your corporate services provider handle payroll and tax clearance, or do you?
Ask directly, because the answer varies by provider and the assumption is expensive. Corporate secretarial packages cover ACRA filings and annual returns. Tax clearance sits in payroll, often a separate line item or out of scope.
Three things to confirm with whoever handles your books:
- Whether IR21 filing is included, billed per employee, or excluded.
- Who watches for the trigger, given that it starts with an HR event rather than a finance one.
- Who holds the withheld monies, and who authorises their release.
At Sleek, IR21 filing is part of the payroll service rather than an add-on, alongside monthly payslips, CPF and SDL submissions, and year-end IR8A. The accounting and tax resources hub sets out where each obligation lives.
What if the departing employee is the director or owner?
The same rules apply, with two wrinkles that catch founders out.
- The concessions don’t cover directors. The 60-day and two-year exemptions specifically exclude company directors. A director who spent 45 days in Singapore still needs clearance where an equivalent employee wouldn’t.
- Personal and company filings are separate. If you’re winding down your own role or the entity, tax clearance runs on the personal side while corporate tax filing services handle the company’s final return. Striking the company off clears neither.
Directors’ fees complicate things further. They’re taxed differently from employment income and often voted after the year they relate to. Fees approved after you’ve filed mean an Additional Form IR21, not a footnote.
What can go wrong: five ways employers get caught out
Each one is a sequencing failure, not a misreading of the rules. Tax clearance is unusual among IRAS and your company’s tax obligations because nothing on a calendar tells you it’s coming.
- HR didn’t tell finance. The resignation is logged, the window opens, and finance hears about it at the final payroll run. By then the deadline has passed.
- The final salary went out on schedule. Payroll ran on the 25th, the withholding never happened, and the employee already has the money IRAS expected you to hold.
- The employee had already left the country. Clearance is still required, and you’re chasing someone in another time zone for details the form needs.
- A bonus was approved after filing. Additional income needs an Amended or Additional Form IR21 before release, and it doesn’t go on next year’s IR8A.
- The employee disputed the withheld amount. Usually because nobody explained the money is theirs and is coming back. A two-line email at notice prevents most of these.
How Sleek helps you clear a departing employee’s tax on time
Tax clearance rarely fails because someone misread IRAS’s rules. It fails because a resignation is an HR event and IR21 is a finance filing, and the handover between the two is where the month disappears.
Sleek runs payroll and tax filing as one service, so a cessation logged in payroll starts the IR21 process automatically. The withholding begins, the form goes in on time, and the Directive gets actioned inside its 10-day window. Corporate tax filing sits with the same team, so the company side and the employee side aren’t tracked from two inboxes.
Stop letting a resignation turn into a tax liability.
Sleek handles IR21, payroll, and corporate tax filing for Singapore companies, so the deadlines run themselves.

FAQs: Tax Clearance in Singapore: A Complete Guide for 2026
Who is responsible for tax clearance, the employer or the employee?
The employer. You file Form IR21, you withhold the monies, and IRAS holds you liable if either step is missed. The employee still gets their own tax bill by post and on myTax Portal, and pays any shortfall directly if what you withheld didn’t cover the assessment.
Do I need tax clearance for a Singapore Permanent Resident?
Only if they’re leaving Singapore permanently, or going on an overseas posting outside IRAS’s six-month concession. If they’re staying in Singapore after ceasing employment with you, get a Letter of Undertaking confirming that and keep it on file. IRAS expects you to produce it on request.
What if the employee has already left Singapore?
You still file Form IR21. The obligation doesn’t lapse because they’ve gone. Ask them to update their mailing and email addresses via the “Update Contact and Notification Preferences” service on myTax Portal before they leave, or the tax bill goes to an address they no longer use.
Can I release the withheld salary before IRAS responds?
No. Wait for the Clearance Directive. If you’ve filed an Amended or Additional Form IR21 after the original, keep holding until the second Directive arrives, even if the first told you to release. Releasing early can leave you liable for your employee’s tax.
What happens if a bonus is paid after I've filed Form IR21?
File an Additional or Amended Form IR21 and get further clearance before the bonus is released. Do not report that income on Form IR8A or through the Auto-Inclusion Scheme the following year, which is the usual mistake. The additional filing triggers a second Clearance Directive.
What if I can't give IRAS one month's notice?
File anyway and state the reason in the form. An immediate resignation is the classic valid reason and IRAS accepts it. Without one, late or missing filings can attract a fine of up to S$5,000, and IRAS weighs your past compliance record when setting any composition amount.
Is tax clearance included in Sleek's payroll service?
Yes. IR21 filing is handled as part of offboarding, alongside monthly payslips, CPF and SDL submissions, leave management, and year-end IR8A through the Auto-Inclusion Scheme. Corporate tax filing for the company itself is a separate service, so confirm which of the two you need.
