If you are an employer in Singapore, one important compliance obligation is the preparation and submission of the IR8A form every year. Filing the IR8A form correctly ensures that you meet your obligations to the Inland Revenue Authority of Singapore (IRAS) and avoid unnecessary penalties.

In this guide, we'll walk you through everything you need to know about the IR8A form, from what it is, why it's important, deadlines, filing methods, and common mistakes to avoid. Let's dive right in!

What is the IR8A Form?

The IR8A form is a compulsory tax form that employers in Singapore must submit to declare the employment income of their employees. It summarises all the earnings, allowances, bonuses, benefits-in-kind, and other income received by employees in the preceding year.

Employers must provide the IR8A form to each employee and submit it to IRAS as part of the annual income reporting requirements.

Key Points:

  • Mandatory for all employers.
  • Covers all local and foreign employees (including directors, part-timers, and retirees receiving income).
  • Reflects income earned in the calendar year (January 1 to December 31).

Who Needs to File the IR8A Form?

Employers must prepare and file the IR8A form for the following employees:

  • Full-time resident employees.
  • Part-time resident employees.
  • Non-resident employees.
  • Company directors.
  • Board members receiving fees.
  • Pensioners.
  • Employees who have left the company but received income in the reporting year.

Note: Employers do not need to file IR8A forms for:

  • Foreigners posted overseas for the entire year with no Singapore-sourced income.

Why is the IR8A Form Important?

The IR8A form ensures that employee income is properly declared for income tax purposes. It supports:

  • Accurate computation of employees' income tax.
  • Transparency and accountability in income reporting.
  • Compliance with Singapore's tax regulations.

Failing to submit IR8A forms can result in penalties and enforcement action by IRAS.

What Should Be Included in the IR8A Form?

When preparing the IR8A form, you must include details such as:

  • Basic Employment Details
  • Basic Types of Income
  • Gross salary, fees, leave pay, wages and overtime pay
  • Bonus
  • Director’s fee
  • Others
    • Allowance
    • Gross Commission for the period
    • Pension
    • Lump sum payment
    • Retirement benefits
    • Contribution made by employer to any pension/provident fund constituted outside Singapore with/without tax concession
    • Excess/voluntary contribution to CPF by employer
    • Gains or profits from Employee Stock Option (ESOP) or other forms of Employee Share Ownership (ESOW)
    • Value of benefits-in-kind

Related Forms: Appendix 8A, Appendix 8B, and Form IR8S

Depending on your company's benefits and remuneration schemes, you may also need to submit:

  • Appendix 8A: For benefits-in-kind.
  • Appendix 8B: For employee share options or awards.
  • Form IR8S: If the employer has made excess CPF contributions or borne the employee's share of CPF contributions.

What is the Auto-Inclusion Scheme (AIS)?

The Auto-Inclusion Scheme (AIS) is an IRAS initiative that allows employers to submit employees' income information electronically, which will then be auto-included in the employees' tax returns. It is mandatory for employers with 5 or more employees to participate in AIS.

Benefits of AIS:

  • Reduces administrative workload.
  • Minimises human errors.
  • Streamlines the filing process.
  • Employees enjoy pre-filled tax returns.

If you are under AIS, you do not need to issue hardcopy IR8A forms to employees unless they request it.

ActivityDeadline

How to File the IR8A Form: Step-by-Step Guide

1. Prepare Employee Income Information

Gather all necessary payroll data for each employee, including salary, bonuses, allowances, benefits-in-kind, stock gains, and CPF contributions.

2. Use myTax Portal

Employers filing manually (rare for 2025) must use IRAS-provided IR8A templates. However, AIS employers will log in to IRAS myTax Portal and submit electronically.

Steps:

  • Login to myTax Portal.
  • Access the "Employers" section.
  • Upload income information (via Form IR8A, Appendix 8A, Appendix 8B, IR8S).
  • Confirm and submit.

3. Verify Employee Details

Ensure you have updated records of employees’ NRIC, FIN numbers, full names, and residential statuses.

4. Check CPF Contributions

Confirm that CPF contributions have been correctly calculated and submitted.

5. Review for Ex-employees

Even if someone left mid-year, you must file an IR8A for the period they worked.

6. Register for AIS (if applicable)

If your company is required to participate in AIS, ensure your registration is completed.

7. Submit by 1 March

File early to avoid system congestion closer to the deadline.
