Singapore | Rising trend of employment income audits

Summary

The Inland Revenue Authority of Singapore (IRAS) has intensified its focus on tax compliance, leading to a noticeable uptick in employment income tax audits. These audits aim to verify the accurate reporting of employment income details under the Auto-Inclusion Scheme (AIS). This trend underscores the growing importance of understanding individual tax compliance obligations and the crucial role employers play in ensuring accurate and timely reporting.

The detail

Common reporting pitfalls

Accurate and timely reporting of employment income is crucial for avoiding penalties and adhering compliance with tax regulations. Employers and employees should focus on the following areas:

Taxable income

Examples of taxable income

AllowancesHousing benefitStock options

Deferred cash paymentsEmployer’s contribution

Relocation allowance
Director’s fee

Certain income components are often overlooked but remain taxable, including:

  • Benefits provided under a wellness program
  • School fees or housing paid directly by employers
  • Gifts exceeding S$200
  • Certain components within severance packages
  • Director’s fees
  • Staff discounts

Equity-based compensation

  • Gains from employee stock options (ESOP) or share ownership (ESOW) plans may be taxable.
  • Equity compensation rules in Singapore are complex and require careful attention.
  • Non-citizens leaving Singapore or ceasing Singapore employment are often taxed under the “deemed exercise” rule.

Ways to maintain compliance

Employers can take the following steps to ensure compliance and minimize audit risks:

  • Thorough record-keeping
    • Maintain accurate payroll records that detail all remuneration components.
    • Track benefits-in-kind and non-standard income, such as complex flexible benefits schemes or health insurance claims.
  • Compliance with the Auto-Inclusion Scheme (AIS)
    • Report all employee income through AIS by the required deadlines.
    • Conduct thorough reviews of submissions to identify and correct errors promptly.
  • Know your reporting obligations
    • Monitor stock option/award plans and ensure gains are reported accurately, particularly under the “deemed exercise” rule for departing non-citizens.
    • Report trailing payments that are sourced to Singapore employment.
  • Training for payroll teams
    • Provide payroll and HR teams with relevant training to understand tax reporting requirements.
    • Ensure teams stay updated with the latest IRAS guidelines and regulations.

Proactive steps to mitigate audit risks

Employers can reduce audit risks and support compliance by taking the following steps:

  • Conduct internal audits (due diligence)

Periodically review payroll and AIS submissions to identify and correct discrepancies.

  • Review employee benefits policies

Reassess policies to ensure proper documentation and reporting of benefits and various remuneration items.

  • Prepare for audit requests

Organize key documents, including annual payroll summaries, employee handbooks, and meeting minutes approving directors’ fees, to be readily available in the event of an audit.

By addressing these areas and implementing proactive measures, employers can enhance compliance and reduce the risk of penalties or audit complications.

What this means

The rise in employment income audits underscores the need for heightened vigilance from both employees and employers. By adopting robust compliance measures, employers can reduce audit risks, safeguard employee trust, and contribute to a transparent tax environment. Proactive steps today can prevent costly errors and ensure alignment with IRAS expectations.

As we observe greater collaboration among statutory bodies, it is plausible that the CPF Board may also intensify its audits. Notably, there is no statute of limitations for CPF Board audits.
