IRAS tax clearance when leaving Singapore

Short answer: Leaving on a work pass usually means your employer runs IR21 tax clearance and withholds your final pay until IRAS is satisfied. IRAS wants roughly one month's notice, so budget the runway before you resign into a thin balance.

When certain foreign employees cease employment in Singapore, go on an overseas posting, or plan to leave Singapore for more than three months, the employer generally has to seek tax clearance from IRAS before releasing final pay. That covers work pass holders broadly, ONE Pass and PEP holders included, under IRAS rules.

The part that surprises people is that this is the employer's obligation rather than yours, which means the timing largely isn't in your hands.

What your employer has to do

IRAS sets out four steps, and each one has a knock-on for you:

1. Notify IRAS via Form IR21 at least one month before cessation or a qualifying departure.
2. Withhold all monies due to you from the date the employer knows of the impending cessation or departure. Not from your last day. From the date they know.
3. Wait for IRAS's directions before releasing anything withheld.
4. File an additional or amended IR21 if further income becomes payable later.

If one month's notice genuinely isn't possible, they still have to file and give reasons. Late filing without a valid reason is the employer's exposure rather than yours, and IRAS cites fines up to S$5,000.

When clearance might not apply

IRAS publishes a list of exceptions, including Singapore citizens, certain SPR situations covered by a Letter of Undertaking where you aren't leaving permanently, short work periods under defined income thresholds, and some intra-group transfers. Don't self-exempt on the strength of a Reddit comment. Have HR confirm it against the live IRAS page, because if the call is wrong it's your final pay and your departure date that absorb the consequence.

Your side of it

Tell HR your departure date early. Withholding often starts from the moment you give notice rather than in your final month, so the sooner they know, the sooner the clock is running on clearance instead of on your patience. Keep payslips, bonus letters, benefits records and your IR8A history tidy while you're at it, because reconstructing them after you've handed back the laptop is miserable.

Ask specifically which components will be withheld and when IR21 will be filed. "We'll sort it out" is not something you can budget against. Keep a cash buffer for the gap, which is what leaving costs is really about, and don't book non-changeable flights on the assumption that clearance comes through the same week. Settle any IRAS GIRO issues before you go, and once you've left, hold on to Singpass and myTaxPortal access where you can so you can confirm nothing is outstanding.

Garden leave and short notice

Where gardening leave applies, IRAS expects clearance at the start of it rather than at the end. Short resignations still need an IR21 filed. And the immigration side, meaning how long you can lawfully stay once the pass is cancelled, is a separate MOM and ICA problem running on its own calendar. You have to coordinate both, because nobody else is looking at the two together.

Unvested RSUs and options

This is the one that costs real money. Foreign employees often face IRAS deemed exercise on unexercised options and unvested share awards at clearance, which treats awards you haven't actually realised as though you had. Ask HR whether the company uses an approved tracking arrangement before you resign into a large vest cliff, not afterwards. The mechanics are in RSU / ESOP tax.

Final-pay freeze clocks, garden-leave filing, and the written questions to put to HR about share-plan tracking all live on IR21 final pay & RSU withholding. If you want the week-shaped version of how IR21, pass cancellation and STVP fit together, that's IR21 / cancel / STVP sequencing.
