If your company in Singapore employs foreign employees or Singapore Permanent Residents, handling tax clearance correctly is an important part of the employee offboarding process.<\/span><\/p>\n When a non-Singapore citizen leaves employment, is transferred overseas, or intends to leave Singapore for an extended period, the employer may need to submit Form IR21 to the Inland Revenue Authority of Singapore (IRAS) and withhold monies payable to the employee until tax clearance is completed.<\/span><\/p>\n This guide explains what employers need to know about IR21 tax clearance in Singapore, including who needs tax clearance, when Form IR21 must be submitted, what employers need to withhold, common exemptions, processing timelines, and the potential consequences of non-compliance.<\/span><\/p>\n For businesses that prefer professional support, WLP provides accounting, tax compliance and payroll-related services to Singapore businesses and can assist employers with managing their broader tax and payroll compliance requirements.<\/span><\/p>\n <\/p>\n\n Form IR21 is a tax clearance form submitted by an employer to IRAS for certain non-Singapore citizen employees.<\/span><\/p>\n The purpose is to allow IRAS to determine whether the departing employee has outstanding Singapore income tax before employment ends or the employee leaves Singapore.<\/span><\/p>\n Generally, tax clearance applies when a non-Singapore citizen employee:<\/span><\/p>\n\n The requirement can apply to foreign employees as well as Singapore Permanent Residents (PRs), subject to specific exemptions.<\/span><\/p>\n IRAS states that the employer is responsible for filing Form IR21 and withholding the relevant monies due to the employee when tax clearance is required.<\/span><\/p>\n <\/p>\n\n The employer, rather than the departing employee, is responsible for submitting Form IR21.<\/span><\/p>\n This means HR, payroll and finance teams should coordinate as soon as they receive notice that an employee covered by the tax-clearance rules is leaving.<\/span><\/p>\n A well-managed offboarding process should therefore connect:<\/span><\/p>\n Employee resignation\/termination \u2192 Payroll \u2192 IR21 filing \u2192 Tax clearance \u2192 Final payment<\/span><\/p>\n This helps reduce the risk of missed deadlines and accidental release of salary or other payments before clearance.<\/span><\/p>\n <\/p>\n\n Employers should generally consider Form IR21 when a non-Singapore citizen employee:<\/span><\/p>\n\n This includes situations such as:<\/span><\/p>\n\n An overseas assignment can also trigger tax-clearance requirements.<\/span><\/p>\n\n Where the employee intends to leave Singapore for more than three months, the employer should assess whether tax clearance is required.<\/span><\/p>\n IRAS specifically notes that the rules apply to foreign employees and Singapore Permanent Residents and cover work pass holders, including Personalised Employment Pass holders.<\/span><\/p>\n <\/p>\n\n A Singapore Permanent Resident may require tax clearance because PRs are non-Singapore citizens.<\/span><\/p>\n However, there is an important exception.<\/span><\/p>\n If a Singapore PR stops working for the employer but is not leaving Singapore permanently, the employer generally does not need to submit Form IR21. Instead, the employer should obtain a Letter of Undertaking (LOU) from the employee confirming that the employee does not intend to leave Singapore permanently.<\/span><\/p>\n Employers should keep the Letter of Undertaking for their records.<\/span><\/p>\n The exemption should not simply be assumed. For example, an overseas posting or circumstances involving overseas employment may require tax clearance.<\/span><\/p>\n When in doubt, employers should check the employee’s specific circumstances against the latest IRAS requirements.<\/span><\/p>\n <\/p>\n\n Not every employee departure requires tax clearance.<\/span><\/p>\n IRAS provides specific scenarios in which tax clearance is not necessary. These include:<\/span><\/p>\n\n The exact exemption criteria can depend on the employee’s circumstances, duration of employment and income.<\/span><\/p>\n Because tax rules can change, employers should verify the applicable exemption directly against the latest IRAS guidance before deciding not to file Form IR21.<\/span><\/p>\n <\/p>\n\n As a general rule, employers should submit Form IR21 at least one month before the employee’s last day of employment, departure or overseas posting, where the tax-clearance requirement applies.<\/span><\/p>\n If the employer receives less than one month’s notice, the employer should file the form as soon as possible and provide the relevant explanation.<\/span><\/p>\n This is why companies should not wait until the employee’s final working day to begin the IR21 process.<\/span><\/p>\n Recommended Employer Timeline<\/span><\/p>\n A practical workflow can look like this:<\/span><\/p>\n Step 1: Employee submits resignation or receives termination notice.<\/span><\/p>\n Step 2: HR determines whether the employee is a Singapore citizen or non-citizen.<\/span><\/p>\n Step 3: Payroll\/finance checks whether an IR21 exemption applies.<\/span><\/p>\n Step 4: Employer prepares the employee’s income and benefits information.<\/span><\/p>\n Step 5: Form IR21 is submitted to IRAS.<\/span><\/p>\n Step 6: Employer monitors the tax-clearance status.<\/span><\/p>\n Step 7: IRAS issues the relevant Clearance Directive.<\/span><\/p>\n Step 8: Employer follows the directive and settles the employee’s withheld monies accordingly.<\/span><\/p>\n <\/p>\n\n When tax clearance is required, the employer generally needs to withhold monies due to the employee from the point the employer becomes aware of the employee’s impending cessation or departure.<\/span><\/p>\n Depending on the circumstances, this may include items such as:<\/span><\/p>\n\n Employers should therefore make sure the payroll team knows about the departure before processing the employee’s final payment.<\/span><\/p>\n A common administrative mistake is allowing the normal payroll process to run without considering the IR21 withholding requirement.<\/span><\/p>\n <\/p>\n\n IRAS allows employers to submit Form IR21 electronically through myTax Portal. Paper filing is also available, although electronic filing provides practical advantages such as immediate acknowledgement and online access to the clearance status and directive.<\/span><\/p>\n Information Employers May Need<\/span><\/p>\n Before filing, employers should ensure that the relevant employee information is available, including:<\/span><\/p>\n\n For employees with share options, restricted shares or other employee share ownership arrangements, additional information may need to be submitted.<\/span><\/p>\n IRAS provides supporting appendices for benefits-in-kind and employee share plans where applicable.<\/span><\/p>\n <\/p>\n\n Employers sometimes confuse Form IR21 with Form IR8A because both relate to employee income reporting.<\/span><\/p>\n They serve different purposes.<\/span><\/p>\n\n In simple terms: IR8A is part of annual employment-income reporting, while IR21 is associated with tax clearance for qualifying non-Singapore citizen employees.<\/span><\/p>\n Submitting one does not automatically replace the other.<\/span><\/p>\n <\/p>\n\n Processing time can vary depending on the case and whether IRAS requires additional information.<\/span><\/p>\n IRAS states that most tax-clearance forms are processed within 21 days. Employers should therefore plan the filing timeline carefully rather than assuming clearance will be immediate.<\/span><\/p>\n Electronic filing is generally preferable because employers can receive acknowledgement and monitor the clearance status through myTax Portal.<\/span><\/p>\n For employees leaving Singapore on a tight schedule, early preparation is especially important.<\/span><\/p>\n <\/p>\n\n Once IRAS completes its assessment, the employer may receive a Clearance Directive.<\/span><\/p>\n The employer should then follow the instructions in that directive.<\/span><\/p>\n Depending on the tax position, the directive may require the employer to:<\/span><\/p>\n\n Employers should not simply release withheld monies without checking the applicable clearance instructions.<\/span><\/p>\n <\/p>\n\n Failing to comply with tax-clearance requirements can create financial and compliance risks for the employer.<\/span><\/p>\n IRAS may take enforcement action for late filing or non-filing. The applicable composition amount can be up to S$5,000 per offence, and further legal consequences may apply. Employers may also face liability where monies that should have been withheld are released incorrectly.<\/span><\/p>\n For this reason, IR21 should be treated as a formal compliance step rather than simply an HR administrative task.<\/span><\/p>\n <\/p>\n\n Starting the process too late can create problems if tax clearance takes longer than expected.<\/span><\/p>\n Better approach: Begin the assessment as soon as the employee’s departure is confirmed.<\/span><\/p>\n\n Foreign employee tax clearance is subject to specific rules and exemptions.<\/span><\/p>\n Better approach: Check the employee’s nationality, status, departure circumstances and applicable IRAS exemption criteria.<\/span><\/p>\n\n PR status does not automatically mean that IR21 can be ignored.<\/span><\/p>\n Better approach: Determine whether the PR is remaining in Singapore permanently and, where applicable, obtain the required Letter of Undertaking.<\/span><\/p>\n\nWhat Is IR21 Tax Clearance in Singapore?<\/b><\/h4>\n
