What Is the IR8A Form in Singapore?

The IR8A form is a mandatory income reporting document that Singapore employers submit to Inland Revenue Authority of Singapore (IRAS) each year. It records the total employment income salary, bonuses, allowances, and benefits-in-kind — that each employee received during the calendar year.

IRAS uses the IR8A data to pre-populate employees’ personal income tax returns via the AIS. This means errors or omissions in your IR8A submission flow directly into your employees’ tax filings — and back to you in the form of queries, amendments, or penalties.

The IR8A is not a payment — it is a declaration. You are telling IRAS what you paid each person, so they can assess the correct tax.

Who Must File the IR8A Form in Singapore?

All Singapore employers must submit the IR8A Form for the following categories of staff:

• Full-time and part-time employees
• Contract workers and temporary staff
• Non-resident employees and directors
• Board members receiving income
• Any individual receiving income subject to Singapore taxation

There is no minimum salary threshold. If you paid an individual any employment income in Singapore, you are required to report it.IR8A reporting is part of the broader filing requirements for small business in Singapore and should never be overlooked—regardless of company size.

IR8A Filing Deadline and Key Dates for 2026

The 1 March deadline is firm. IRAS does not grant routine extensions. If you miss it, you face penalties — and your employees may have their personal tax returns delayed or inaccurately pre-filled. IRAS recommends submitting at least one week before the deadline to allow time to resolve any AIS upload rejections.

What Income to Declare on the IR8A

You must declare all employment income earned in the 2025 calendar year. This covers:

• Basic salary
• Bonuses and commissions
• Overtime pay
• Housing and transport allowances
• Directors’ fees
• Retirement gratuities and ex-gratia payments
• Benefits-in-kind (company car, club memberships, insurance premiums)
• Employee stock options and share ownership plan gains
• Leave encashment (now reported under “Other Allowances” from YA2026)

Additional Forms You May Need:

Depending on the types of compensation your employees receive, you may need to submit additional forms alongside the IR8A. Note that Form IR8S has been discontinued by IRAS for YA2026 — excess CPF contributions are now reported directly under item d6 of the main IR8A form.

Form	When to File
Appendix 8A	When employees receive benefits-in-kind (company car, accommodation, club memberships)
Appendix 8B	When employees realise gains from stock options or employee share plans
Form IR8S	Discontinued for YA2026. Report excess or voluntary CPF contributions under item d6 of the IR8A instead.

Filing via the Auto-Inclusion Scheme (AIS)

What Is AIS?

The Auto-Inclusion Scheme (AIS) allows employers to electronically submit employee income data directly to IRAS. If you have 6 or more employees, joining AIS is mandatory.

Once submitted, employee income is pre-filled in their personal tax returns, which improves accuracy and reduces questions from IRAS.

How to Submit IR8A via AIS:

1. Log in to myTax Portal
2. Navigate to Employers > Submit Employment Income Records.
3. Upload your employee income data in the AIS-compatible file format, or enter it manually for small teams.
4. Review and verify each record before confirming submission.
5. Save your acknowledgement receipt as proof of filing.

Deadline: All submissions via AIS must be completed by 1 March.

📌 Tip: Even if you have fewer than 6 employees, it’s still advisable to join AIS for faster, error-free reporting.

Common IR8A Filing Mistakes (and How to Avoid Them)

Even experienced HR teams and accountants can slip up. Here are top 5 mistakes:

Mistake #1: Missing out on benefits-in-kind

Company cars, club memberships, and employer-paid insurance premiums are taxable benefits. They must be declared in Appendix 8A, not left out because they are not cash payments. IRAS can — and does — query employers who show zero benefits-in-kind when payroll records suggest otherwise.

Mistake #2: Incorrect reporting of stock options

If your employees participated in an Employee Share Option (ESOP) or Employee Share Ownership Plan (ESOW), the gains are taxable at the point of exercise or vesting. These must be reported in Appendix 8B — even if the employee has since left the company.

Mistake #3: Using outdated employee identification details

IRAS matches IR8A records to individuals using their NRIC or FIN number. Outdated identification numbers, incorrect names, or wrong employment dates cause AIS rejections that require resubmission.

Mistake #4: Ignoring CPF discrepancies

If CPF payments were made incorrectly or not recovered, file Form IR8S.

Mistake #5: Late submissions

The 1 March deadline applies to all AIS submissions. Under Section 94 of the Income Tax Act, late or incorrect IR8A filing carries a fine of up to S$5,000 and, in default of payment, imprisonment for up to 6 months. There is no grace period for administrative delays.
