Detailed Guide On Filing A Singapore IR8A Form For Employee Earnings

As an employer, it is essential to navigate the intricacies of tax compliance and ensure accurate reporting of your employees’ income. 

In this detailed guide, we will walk you through the entire process of filing the Singapore IR8A Form, providing step-by-step instructions and valuable insights. From understanding the eligibility criteria to gathering the necessary information and submitting the form, we will cover all the essential aspects to help you streamline the process.

What Is A Singapore IR8A Form?

Form IR8A is the employer’s return of an employee’s remuneration. Under section 68(2) of the Income Tax Act and the annual gazette notice to employers, businesses must prepare Form IR8A for relevant employees who were employed in Singapore during the year, by 1 March of the following year. Depending on the facts, employers may also need Appendix 8A or Appendix 8B, while Form IR8S applies only where relevant for periods prior to YA 2026.  

Form IR8A is used to report employment income such as salary, bonus, allowances, director’s fees, and certain other remuneration items. In practice, it sits within Singapore’s annual employer reporting process for individual income tax. The form helps IRAS assess employees accurately and, for AIS employers, allows income information to be pre-filled into employees’ electronic tax returns. This reduces employee errors, speeds up tax filing, and makes payroll controls more important because mistakes in payroll coding can flow into tax reporting.  

Who Does the Employer Prepare the Singapore IR8A Form For?

The Singapore IR8A Form applies to the classes of persons listed in the annual section 68(2) gazette notice. In broad terms, employers should prepare it for:  

• Full-time resident employees  
• Part-time resident employees  
• Non-resident employees, including those based overseas who are required to render service in Singapore during the year  
• Company directors, including non-resident directors  
• Board members receiving board or committee member fees  
• Employees who have left the organisation but still received income in the year, such as stock option gains  
• Pensioners  

Quick reference table 

Category	IR8A generally required?	Notes
Full-time or part-time resident employee	Yes	Include relevant remuneration for the year.
Non-resident employee working in Singapore	Yes	Subject to the IR21 tax-clearance carve-outs below.
Director or board member with fees	Yes	Includes non-resident directors.
Former employee with stock option/share gains	Yes	Reporting may still be required after departure.
Sole proprietor or partner	No under AIS	Their income is generally trade income, not employee income.

Who is Exempted from IR8A Form Filing?

Certain non-resident employees may be excluded from IR8A reporting where their employment income has already been covered through Form IR21 tax clearance. Under the current gazette notice:

• If tax clearance was sought by filing Form IR21 for a non-resident employee, the employment income covered by that IR21 filing should be excluded from Form IR8A; and  
• Employers are not required to file Form IR8A for such non-resident employees if they have only employment income for which clearance had been sought by filing Form IR21.  

Employers should avoid using broad assumptions such as “all foreigners working abroad are exempt.” The correct analysis depends on whether the employee was employed in Singapore, whether services were rendered in Singapore, and whether the relevant income has already been dealt with through IR21 tax clearance.

Required Supporting Forms for IR8A Form Submission in Singapore

When filing the form for employee earnings, certain supporting forms may be required to provide additional details. These forms include:

Appendix 8A

Appendix 8A is used for employees who were provided with benefits-in-kind. It allows employers to declare non-cash benefits granted during the year, such as accommodation, prescribed benefits, or other taxable benefits-in-kind, based on the applicable IRAS guidance.

Appendix 8B

Appendix 8B is required where employees derived gains or profits from Employee Stock Option (ESOP) Plans or other Employee Share Ownership (ESOW) Plans. It captures the reportable gains from those plans for tax purposes.

Form IR8S

Form IR8S should be treated with caution in current articles because IRAS states it is applicable where applicable prior to YA 2026. For current-year IR8A guidance, employers should verify whether they are dealing with an earlier year that still requires IR8S, rather than assuming it is part of every annual filing.

Step-by-Step: How to Submit Singapore IR8A Form to IRAS

To stay compliant, employers should first determine whether they are under the Auto-Inclusion Scheme (AIS). Under current IRAS guidance, AIS submission is mandatory for employers who have 5 or more employees in 2025, those that received a Notice to File Employment Income of Employees Electronically, or those that received the relevant letter informing them to join AIS.

Follow these steps:

1. Confirm whether your organisation is under AIS 
   If you are an AIS employer, you must submit employees’ employment income information to IRAS electronically by 1 March. AIS employers do not need to issue hardcopy Form IR8A and appendices to employees.  
2. Prepare complete employment income records 
   Gather salary, bonus, allowances, director’s fees, benefits-in-kind, share-based gains, and other relevant payroll data for the reporting year. Where employees transferred between entities because of restructuring or merger, IRAS allows reporting by the respective entity according to contract periods or combining the employment income information under the new entity.  
3. Prepare the relevant forms and appendices 
   Prepare Form IR8A and, where applicable, Appendix 8A or Appendix 8B. Review carefully whether IR8S is relevant for an earlier year rather than assuming it applies to current filings.  
4. Submit using current IRAS channels 
   IRAS currently supports two primary electronic submission approaches for AIS employers:  
   • a. payroll software integrated with the AIS API; or  
   • b. the Submit Employment Income Records digital service on myTax Portal.  
5. If you are not under AIS, furnish the forms to employees 
   Employers who are not under AIS must provide hardcopy Form IR8A and the relevant appendices to employees by 1 March so the employees can file their own income tax returns. Employers not under AIS generally do not submit those hardcopy forms to IRAS.  

Common compliance pitfalls to avoid

Many IR8A errors come from payroll data rather than the form itself. Common problem areas include wrong employee ID numbers, omitted leavers, misclassified benefits-in-kind, and reporting partner or sole-proprietor income as employee income. IRAS’ amendment guidance also shows that not every mistake is handled the same way: some require an amendment immediately, while others should simply be corrected in the next year’s submission. For employers with growing headcount, another frequent issue is not realising that AIS participation can become mandatory once the threshold or notice condition is met. A practical best practice is to reconcile payroll totals, director fee approvals, benefits registers, and share-plan records before filing season starts. 

Is It Possible to Amend the IR8A Form After Submission?

Yes. IRAS allows employers to amend submitted records, but the method depends on the type of error. For wrong income submitted, IRAS indicates that a revision submission is generally recommended because it overwrites the previous record with the full and correct values. Amendment submissions can also be used in certain cases by submitting only the differences.

Current IRAS guidance distinguishes between common scenarios:

1. Wrong personal particulars such as address — amendment is generally not required if the error does not affect income and deduction amounts; correct it in the subsequent year’s AIS submission.  
2. Wrong employee ID number — submit amendment records immediately. IRAS states that two records may be needed to correct both the incorrect and correct ID record.  
3. Wrong income submitted — submit a revision or amendment based on IRAS’ correction rules.  
4. Omitted employee record — submit the omitted record immediately and do not re-submit previously submitted unaffected records.  

Rather than relying on older instructions to email IRAS for routine demographic changes, employers should follow the current IRAS amendment workflow and use the official amendment guidance and checker where relevant.
