What is IR21 tax clearance when leaving Singapore?

For many foreign employees, employers must file Form IR21 with IRAS and withhold monies due before releasing final pay when employment ends or you leave Singapore for more than three months.

How much notice must my employer give IRAS before I leave?

IRAS generally expects at least one month’s notice via IR21 before cessation or qualifying departure. If that is impossible, HR must still file and explain — late filing can penalise the employer.

Why is my final salary frozen when I resign?

Employers must withhold all monies due from the date they know you are leaving until IRAS clears the case. Budget runway; do not resign into a thin balance assuming last-month pay arrives on time.

Do Singapore citizens need IR21 tax clearance?

Citizens are generally outside the standard foreign-employee IR21 withholding regime. Some SPR situations and short assignments have exceptions — have HR confirm against the live IRAS page rather than self-exempting.

What should I do before my last day for tax clearance?

Give HR written leave dates early, keep payslips and IR8A history, settle IRAS GIRO issues, and confirm when withheld amounts will be released after IRAS direction.

IRAS tax clearance when leaving Singapore

How Form IR21 works for foreign employees — employer withholding, one-month notice, exceptions, and what you should do before your last day.

Short answer: Leaving on a work pass usually means employer IR21 tax clearance and withheld final pay. IRAS wants ~one month’s notice — budget 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, employers generally must seek tax clearance from IRAS before releasing final pay.

This applies to work pass holders, including categories such as ONE Pass and PEP holders, under IRAS rules.

What employers must do

Per IRAS guidance:

Notify IRAS via Form IR21 at least one month before cessation / qualifying departure
Withhold all monies due to the employee from the date the employer knows of the impending cessation or departure
Follow IRAS directions before releasing withheld amounts
File additional/amended IR21 if further income becomes payable later

If one month’s notice is impossible, employers must still file and provide reasons. Late filing without valid reason can attract employer penalties (IRAS cites fines up to S$5,000).

When clearance may not be required

IRAS lists exceptions — including Singapore citizens, certain SPR situations with a Letter of Undertaking (not leaving permanently), short work periods under defined income thresholds, and some intra-group transfers. Do not self-exempt from a Reddit comment; have HR confirm against the live IRAS page.

What you should do as the employee

Tell HR your departure date early — withholding often starts at resignation notice, not only in the final month
Keep payslips, bonus letters, and benefits records tidy
Ask which components will be withheld and when IR21 will be filed
Keep a cash buffer — see leaving costs
Do not book non-changeable flights that assume same-week clearance
After leaving, keep Singpass/myTaxPortal access where possible to confirm no outstanding tax

Garden leave and short notice

IRAS expects clearance at the start of gardening leave when applicable. Short resignations still require IR21; immigration stay windows after pass cancellation are a separate MOM/ICA problem — coordinate both calendars.

Unvested RSUs and options

Foreign employees often face IRAS deemed exercise on unexercised options / unvested share awards at clearance. Ask HR whether the company uses an approved tracking arrangement before you resign into a large vest cliff. Detail: RSU / ESOP tax.
