IR8A in Singapore: The Employer's Guide for YA 2026

If you paid anyone in Singapore during 2025, you have a Form IR8A to file by 1 March 2026. That includes directors who took a fee, part-timers who worked one shift, and the founder who finally put themselves on payroll. There are no size exemptions, no "we'll do it next year" buttons, and the penalty for missing the deadline is a fine of up to S$5,000 and possible imprisonment.

This guide walks through what IR8A is, who must file, the supporting forms (and which one IRAS just retired), and how the Auto-Inclusion Scheme changes the workflow. We've handled hundreds of IR8A submissions for Singapore SME clients, so we'll flag the mistakes IRAS most often picks up.

What is IR8A?

Form IR8A is the annual return Singapore employers file with IRAS to report employment income paid to each employee for the calendar year. It feeds directly into employees' personal income tax assessments. Employers do not pay tax on the IR8A itself; the return reports the numbers that IRAS uses to assess the employee's tax. (IRAS, Reporting employee earnings)

The annual filing window opens in the months leading up to the 1 March deadline. Income earned in 2025 must be reported by 1 March 2026 (Year of Assessment 2026).

Who must file IR8A

Every Singapore employer who paid employment income in the calendar year must file. That includes:

• Private limited companies, including dormant ones that paid director's fees
• Sole proprietorships and partnerships with even one employee
• Foreign-headquartered companies with staff working in Singapore
• Family offices, foundations, charities, and any other entity on the payroll side of a payment

The form covers full-time and part-time employees, resident and non-resident staff, company directors, board members, pensioners, and ex-employees who received income (such as deferred bonuses or share gains) during the year. The only employees you do not include on IR8A are foreign staff who left Singapore mid-year and were already cleared via Form IR21.

If you're not sure whether your structure qualifies, our guide on sole proprietorship vs Pte Ltd covers the entity-level rules.

Who you do NOT report on IR8A

Three groups are commonly mis-included:

• Independent contractors and freelancers. If they invoice you and pay their own taxes, they are not employees and do not belong on IR8A. Many founders bundle their lawyer or designer onto the form by mistake.
• Foreigners working wholly outside Singapore. If the employee never performs services in Singapore, the income is not Singapore-sourced and IR8A does not apply. Incidental work performed during a Singapore visit IS reported.
• Foreign employees already cleared by IR21. Once you file IR21 for a ceasing employee, that employee's income is reported on IR21, not IR8A.

The IR8A form family at a glance

IR8A travels with three (sometimes optional) supporting forms. Knowing which one applies to your team prevents the most common late-filing trap.

The retirement of IR8S is the headline change for YA 2026. If your payroll software still creates an IR8S for current-year items, update it. (IRAS, Explanatory Notes for IR8A YA 2026)

The Auto-Inclusion Scheme (AIS)

If you employed five or more people at any point in the previous year, you are required to be on the Auto-Inclusion Scheme. AIS is mandatory once the threshold is crossed; if you later drop below five staff, you stay enrolled. Approximately 123,000 employers are submitting through AIS for YA 2026, covering more than two million employees. (IRAS, Auto-Inclusion Scheme)

Under AIS:

1. You transmit IR8A and any appendices electronically to IRAS through myTax Portal, the Validation and Submission Application (VSA), or AIS-enabled payroll software like Xero Payroll.
2. The income data pre-fills each employee's personal tax return.
3. You do not give employees a hardcopy IR8A; a statement of earnings is enough for their records.

How to check if you're on AIS. Log into myTax Portal under "Employer Services" or look for the IRAS notice posted to the company's registered address each year. Employers below the five-employee threshold can still join AIS voluntarily; we recommend it because it removes the year-end paper chase.

If you're not on AIS. Smaller employers who have not opted in must still prepare a hardcopy IR8A and any appendices for each employee by 1 March. You give them to your employees for their personal tax filing, retain copies for your records, and do not submit anything to IRAS. The deadline and penalties apply equally; only the delivery channel differs.

How to file IR8A: a step-by-step

If you run payroll on Xero, our Singapore payroll guide walks through the monthly cadence. The IR8A submission itself is the year-end ceremony on top.

1. Confirm employee details by mid-January. NRIC or FIN, full name, residential address, and date of birth must match IRAS records. Mismatches are the most common rejection reason.
2. Reconcile gross wages, bonuses, and allowances against your monthly payroll reports. Include off-cycle items like AWS, retention bonuses, and any gross-up payments.
3. Match CPF contributions to CPF Board records for the year. If your CPF rates changed mid-year (common for staff crossing age bands), our CPF contribution rates guide shows how to handle the transitions.
4. Capture benefits-in-kind on Appendix 8A. Company cars, accommodation, drivers, mobile phones, club fees: each has its own valuation rule.
5. Capture share scheme gains on Appendix 8B if any employee exercised an option or had shares vest during the year.
6. Submit through your AIS channel by 1 March (or distribute hardcopies to employees if you're not on AIS). IRAS recommends submitting at least a week before the deadline to leave time for any rejection corrections.
7. Issue a statement of earnings to each employee for their records, even though the data is auto-included.
8. File the records. IRAS requires you to keep payroll and IR8A records for at least 5 years from the relevant Year of Assessment. Digital storage is fine; we keep ours in the client's Xero Files. (IRAS, Record-keeping requirements)

Penalties: what late or wrong filing actually costs

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. Repeat or wilful offences attract higher penalties and IRAS enforcement, including audits of the wider payroll. The current penalty structure is set out in the Section 68(2) gazette for YA 2026.

In practice, IRAS sends a reminder for first-time misses. The fines bite when filings are wrong rather than late: misreporting an allowance as exempt, omitting BIK, or missing one employee from a multi-entity payroll. The audit cost (your time and ours) far outweighs the IR8A itself.

The five mistakes IRAS flags most

We see the same errors every year, in roughly this order:

1. NRIC or FIN mismatches. A typo on the IC number means the income lands in nobody's tax return.
2. Missing benefits-in-kind. Founders forget that the company-paid mobile bill, the club membership, or the housing allowance is taxable.
3. Director's fees omitted from dormant companies. If a holding company paid the director SGD 1, IR8A is still required.
4. Voluntary or excess CPF reported wrong. From YA 2026 this lives in IR8A item d)6, not on the retired IR8S.
5. Foreign employee filed on IR8A when IR21 was required. Once a foreigner gives notice, you must file IR21 at least one month before their last day and withhold the final salary; IR8A is then not used for that employee. (IRAS, Tax clearance for foreign and SPR employees)

Frequently asked questions

Do sole proprietorships and partnerships need to file IR8A? Yes. Any business that paid employment income in the year files IR8A, regardless of the legal form. The form covers the people you paid; it does not depend on what kind of entity you are.

My company was dormant in 2025. Do I still need to file? Only if the dormant company paid employment income, including director's fees. A dormant company that paid no one has nothing to file.

Is IR8S still required for YA 2026? Not for current-year items. IRAS has discontinued IR8S for YA 2026; voluntary CPF, excess CPF refunds, and similar adjustments are reported in IR8A item d)6. IR8S can still apply for adjustments relating to periods before YA 2026.

Do I still need to give employees a hardcopy IR8A? Not under AIS; the income flows straight into each employee's tax return on myTax Portal. If you are not on AIS, you must give a hardcopy IR8A to every employee by 1 March. Either way, give a statement of earnings for the employee's records.

What if a foreign employee leaves Singapore in the middle of the year? File IR21 (tax clearance) at least one month before their last day, and withhold their final salary until IRAS issues a clearance directive. Do not include that employee on IR8A.

When does the AIS submission window open? myTax Portal opens for IR8A submissions in the months leading up to 1 March. We recommend submitting in February so any rejected lines have time to be corrected before the deadline.
