Form IR8A in Singapore: The Employer’s Guide (2026)
By Lucas Seah, Founder of Excellence Singapore Group | Last Updated: June 2026
Form IR8A is the annual Return of Employee’s Remuneration that every Singapore employer must prepare for each employee, reporting salary, bonuses, allowances, and other earnings for the year. It is filed under the Auto-Inclusion Scheme (AIS) by 1 March, and AIS is mandatory for employers with 5 or more employees, or who received the Notice to File. The figures flow straight into your employees’ tax assessments.
This guide explains what Form IR8A is, who must file it, when it is due, how it differs from Appendix 8A, Appendix 8B, and Form IR8S, and how to submit it without triggering a penalty.
Key Takeaways
- Form IR8A reports each employee’s remuneration (salary, bonus, allowances, and more) to IRAS for the year; it is the employer’s return, not the employee’s.
- The AIS submission deadline is 1 March each year, so 2025 earnings are reported by 1 March 2026.
- AIS is mandatory for employers with 5 or more employees, or who received the Notice to File from IRAS.
- Appendix 8A covers benefits-in-kind, Appendix 8B covers ESOP and ESOW gains, and Form IR8S covers excess or voluntary CPF; you file each only when it applies.
- Late or incorrect submission can attract a penalty of up to S$5,000 under the Income Tax Act.
What Is Form IR8A?
Form IR8A is an employer’s annual Return of Employee’s Remuneration, required under section 68(2) of the Income Tax Act. Every employer must complete it for each employee who worked during the year, reporting wages, bonuses, commissions, allowances, and director’s fees. The form tells IRAS what each person earned so their individual tax can be assessed.
It is the employer’s obligation, not the employee’s. Your staff do not fill in IR8A themselves. Instead, you prepare and submit the information on their behalf, and the earnings then appear automatically in their own tax filing if you are on the Auto-Inclusion Scheme.
A common confusion: IR8A is not a tax payment. It is a disclosure of pay. The actual tax sits with the employee, who is assessed on the income you reported. Your job is to report it accurately and on time.
Form IR8A is the core form. Three companion forms (Appendix 8A, Appendix 8B, and Form IR8S) attach to it only when specific situations apply, which we cover in the comparison table below.
Who Must File IR8A and Join the Auto-Inclusion Scheme (AIS)?
Every employer must prepare Form IR8A for each employee, but how you submit depends on the Auto-Inclusion Scheme. AIS is mandatory for employers with 5 or more employees, or for any employer who received the Notice to File from IRAS. Under AIS, you submit employment income data electronically and it flows directly into your employees’ tax returns.
If AIS applies to you, you do not hand paper IR8A forms to staff. You transmit the data to IRAS, and the figures are pre-filled in each employee’s Income Tax Return. This removes a step for employees and reduces reporting errors.
In our payroll work across thousands of SME engagements, the most frequent slip is an employer that has just crossed the 5-employee line and does not realise AIS has become compulsory. The headcount test catches growing firms by surprise, so check it each year before the filing window.
Which employees do you report?
You report full-time and part-time resident employees, non-resident employees, company directors, board members, and pensioners, among others. The scope is broad. If someone earned employment income through your company during the year, you generally need to include them in your IR8A reporting.
When Is the IR8A and AIS Deadline?
The AIS submission deadline is 1 March each year. For income earned in 2025, the IR8A and AIS information must reach IRAS by 1 March 2026. The deadline is fixed and falls on the same calendar date every year, which makes it easy to plan for.
Submit early rather than at the last minute. The myTax Portal and payroll software channels get busy in late February, and a rejected file close to the deadline leaves little room to correct and resubmit. We aim to file client IR8A returns well before 1 March.
Because the date never moves, there is no excuse the system accepts for missing it. Treat 1 March like CPF: a recurring, non-negotiable payroll obligation, not an annual scramble.
IR8A vs Appendix 8A vs Appendix 8B vs IR8S
Form IR8A is always required, but the three companion forms apply only in specific cases. Appendix 8A reports benefits-in-kind, Appendix 8B reports gains from share schemes, and Form IR8S reports excess or voluntary CPF contributions. The table below shows what each form covers and when you need it.
| Form | What it reports | When you need it | Required for |
|---|---|---|---|
| Form IR8A | Annual Return of Employee’s Remuneration: salary, bonus, commission, allowances, director’s fees | Always, for every employee who earned income during the year | Every employee |
| Appendix 8A | Benefits-in-kind, such as accommodation, a company car, or other non-cash perks | Only where you provided taxable benefits-in-kind to staff | Affected employees only |
| Appendix 8B | Gains or profits from share schemes (ESOP and ESOW) | Only where employees had gains from stock options or share awards | Affected employees only |
| Form IR8S | Excess or voluntary CPF contributions that may be refundable | Only where CPF was over-contributed or contributed voluntarily | Affected employees only |
In practice, most small employers file IR8A alone. You add Appendix 8A only if you gave staff taxable benefits such as accommodation or a company car. Appendix 8B comes in only for stock-option or share-award gains. Form IR8S is needed only where CPF was over-contributed or contributed voluntarily and the excess may be refundable. File each companion form for the affected employees only, not for everyone.
How Do You Submit IR8A Under AIS?
Most employers submit through AIS-approved payroll software or directly via the myTax Portal at IRAS. Both channels transmit the IR8A and any appendices electronically, so the data pre-fills your employees’ tax returns. The right channel depends on your headcount and whether your payroll system supports AIS.
There are two common routes:
- AIS-approved payroll software: if your payroll system is on the IRAS AIS software list, it can validate and transmit the data straight from your pay records. This suits employers running regular payroll in a supported system.
- myTax Portal (Submit Employment Income Records): you can key in or upload the records online using your Singpass or Corppass. Smaller employers often use the online application or the offline validation tool to prepare the file first.
Whichever route you take, reconcile your IR8A figures against your payroll and CPF records before you transmit. A clean reconciliation at year-end is far easier than amending a return after employees have already filed. If payroll administration is stretching your team, outsourced accounting and payroll handles the year-end IR8A reporting alongside the monthly run.
What Are the Penalties for Late or Wrong Filing?
Late or non-submission of the IR8A or AIS records can lead to a penalty of up to S$5,000 under the Income Tax Act, and persistent default can carry further consequences. IRAS treats employer reporting as a legal duty, not an optional courtesy, because the data underpins every affected employee’s tax assessment.
Accuracy matters as much as timing. Under-reporting income, omitting a bonus, or leaving out a benefit-in-kind can all draw scrutiny and corrections. If you spot an error after submitting, amend the records promptly through the same channel rather than waiting for IRAS to flag it.
The simplest protection is process: a payroll calendar that closes the year, reconciles to CPF, and files before 1 March. If your figures are right and your submission is early, the penalty regime never becomes your problem.
Frequently Asked Questions
Where can I download Form IR8A?
You generally do not download and hand out IR8A if you are on the Auto-Inclusion Scheme, because you submit the data electronically to IRAS instead. The relevant forms and the offline validation tool are available on the IRAS website under the AIS for employment income pages. AIS is mandatory for employers with 5 or more employees.
When must I submit IR8A in Singapore?
The AIS submission deadline is 1 March each year. Income earned in 2025 must be reported to IRAS by 1 March 2026. The date is fixed and does not move, so build it into your payroll calendar. Submit early, because the channels get busy near the deadline and a rejected file leaves little time to correct.
What is the difference between IR8A and IR8S?
Form IR8A is the main annual return of an employee’s remuneration, required for every employee. Form IR8S is a companion form you file only when there have been excess or voluntary CPF contributions that may be refundable. In short, IR8A reports pay for everyone, while IR8S deals specifically with over-contributed or voluntary CPF.
Is IR8S still required?
Form IR8S is still required, but only in specific cases. You file it when excess or voluntary CPF contributions have been made and the excess may need to be refunded or accounted for. If your CPF contributions are all within the ordinary mandatory limits, you do not need IR8S. It is a situational companion form, not a universal one.
Do I need to file IR8A?
Yes, if you are an employer with employees who earned income during the year. Every employer must prepare Form IR8A for each employee. If you have 5 or more employees, or you received the Notice to File, you must submit through the Auto-Inclusion Scheme by 1 March. Smaller employers may still be required to report through AIS in certain cases.
What happens if I miss the IR8A deadline?
Missing the 1 March deadline can attract a penalty of up to S$5,000 under the Income Tax Act, and continued default can lead to further action. Because the data feeds every affected employee’s tax assessment, IRAS treats employer reporting as a legal obligation. If you realise you will be late or have made an error, correct it through the same channel as soon as possible.
