Singapore IR8A Guide for employees and employers

Learn what Form IR8A is, how AIS works, what employment income is reported, and what employees should check before filing Singapore income tax.

Form IR8A AIS Submission Employment Income Tax Filing Checks

Quick answer

Form IR8A is the employment income form used in Singapore to report salary, bonus, allowances, benefits and other employment income. If an employer is under AIS, the employment income information is submitted directly to IRAS and may be pre-filled when the employee files income tax.

What is Form IR8A?

Form IR8A is a Singapore employment income form prepared by employers. It reports an employee’s income for the year, such as salary, bonus, allowances, director’s fees, benefits and other employment-related payments.

For employees

IR8A helps employees check their annual employment income before filing Singapore personal income tax.

For employers

Employers use IR8A information to report employee income to IRAS, especially if they are under AIS.

For tax filing

IR8A information may be used to pre-fill employment income in the employee’s tax filing system.

Who needs Form IR8A?

Employers generally prepare IR8A information for employees who received employment income during the year. This can include full-time employees, part-time employees, directors and employees who received taxable employment income.

Full-time employees

Regular employees who receive salary, bonus or allowances may have employment income reported in IR8A.

Part-time employees

Part-time employees may also be included if they received reportable employment income during the year.

Directors

Director’s fees and employment-related payments may need to be reported depending on the situation.

What is AIS?

AIS means Auto-Inclusion Scheme. Under AIS, employers submit employees’ employment income information directly to IRAS. This can make tax filing easier because the employee’s income may already be pre-filled.

Important reminder

Pre-filled does not mean automatically correct. Employees should still review salary, bonus, allowances, CPF-related information and benefits before submitting their income tax return.

What income is shown in IR8A?

IR8A can include different types of employment income. The exact items depend on what the employee received during the year.

IR8A Item What It Means Example
Salary Regular employment salary earned during the year. Monthly salary from January to December.
Bonus Bonus, AWS, performance bonus or other incentive payments. 13th month payment or annual performance bonus.
Allowances Employment allowances paid to the employee. Transport allowance, meal allowance or fixed allowance.
Director’s fees Fees paid to company directors. Director fee approved and paid during the year.
Benefits-in-kind Taxable non-cash benefits provided by the employer. Housing benefit, car benefit or other staff benefits.
Employee CPF Employee CPF contributions relevant to tax relief reporting. Employee CPF deducted from salary.

IR8A, IR8S, Appendix 8A and Appendix 8B

IR8A is the main employment income form, but some employees may have additional forms depending on CPF, benefits or employee share plan situations.

Form Purpose Common Situation
Form IR8A Reports employment income for the year. Salary, bonus, allowances and employment income.
Form IR8S Reports CPF-related situations where applicable. Excess or voluntary CPF contribution situations.
Appendix 8A Reports benefits-in-kind. Housing, car or other taxable employee benefits.
Appendix 8B Reports gains or profits from employee share options or share ownership plans. Stock options, share plans or employee equity benefits.
Note: Not every employee will have IR8S, Appendix 8A or Appendix 8B. These forms depend on the employee’s CPF, benefit and share plan situation.

What employees should check

Employees should compare IR8A information with payslips, CPF records, bonus letters and bank payments. This helps identify missing bonus, wrong salary period, incorrect allowance classification or CPF reporting errors.

Salary and bonus

Check whether your total annual salary, AWS, bonus and incentives are included correctly.

Allowances and benefits

Check transport allowance, meal allowance, housing benefit, car benefit or other staff benefits.

CPF and tax filing

Compare your CPF records and IRAS pre-filled income before submitting your tax return.

What employers should prepare

Employers should keep accurate payroll records throughout the year so IR8A information can be prepared correctly. Payroll errors can affect employees’ tax filing and may create follow-up questions from employees or IRAS.

Payroll records

Keep monthly payroll summaries, payslips, employee movement records and payroll adjustment details.

CPF records

Keep CPF contribution records so employees can compare CPF details with salary and tax filing information.

Bonus and benefits

Keep bonus approvals, director fee approvals, benefit records and supporting documents.

When is IR8A submitted?

Employers under AIS generally submit employment income information to IRAS after the year ends and before the tax filing season. Employees should check the latest IRAS deadline each year because filing dates and administrative requirements may change.

For salary planning content, it is safer to confirm the latest AIS and IR8A deadline directly with IRAS instead of relying only on an old saved date.

How IR8A connects with CPF and tax

IR8A is for income tax reporting, while CPF contribution is reported and paid under CPF rules. However, both are connected because salary, bonus and CPF contributions affect an employee’s tax position.

Item Connected To Why It Matters
Salary Income tax and CPF Salary affects both employment income reporting and CPF contribution planning.
Bonus Income tax, CPF and annual income Bonus may increase annual taxable income and may also affect CPF treatment.
Employee CPF CPF relief and tax filing Employee CPF may be relevant when checking CPF relief and tax filing details.
Benefits-in-kind Taxable employment benefits Certain non-cash benefits may need separate reporting through Appendix 8A.

Common IR8A mistakes

These are common areas employees and employers should review before relying on IR8A or AIS information.

Forgetting bonus

Bonus, AWS and incentives should be reviewed carefully when checking annual employment income.

Ignoring benefits

Benefits-in-kind may need separate reporting through Appendix 8A if they are taxable.

Not checking AIS data

Employees should still review pre-filled income before submitting their tax filing.

Official sources to check

For official IR8A, AIS and employment income reporting rules, always check IRAS directly.
