Frequently Asked Questions

Does every Singapore company need an accountant or tax agent?

Not necessarily. Singapore companies are responsible for maintaining proper accounting records and meeting their filing and tax obligations. While appointing an accountant or tax agent is not always mandatory, professional support can help ensure accurate records, timely filings, and compliance with Singapore regulations.

What's the difference between an accountant and a registered tax agent?

An accountant primarily handles bookkeeping, financial records, financial statements, and accounting-related matters. A registered tax agent is authorised to provide tax-related services and deal with tax matters with the Inland Revenue Authority of Singapore (IRAS) on behalf of clients.

need to register for GST?

GST registration is generally required when a business meets the applicable compulsory registration criteria, including the prescribed taxable turnover threshold. Businesses that do not meet the compulsory criteria may also be able to register voluntarily, subject to IRAS requirements.

Can IBS handle everything from Singapore while I'm based overseas?

Yes. IBS can support overseas business owners with Singapore accounting, bookkeeping, tax filing, GST compliance, payroll, and other finance-related requirements remotely, helping you manage your Singapore operations without needing to be physically present.

What happens if I miss a filing deadline?

Missing a filing deadline can result in late filing penalties, additional compliance requirements, or other enforcement action depending on the filing involved. It is important to address missed deadlines promptly and ensure future filings are submitted on time.

Is bookkeeping included, or is it a separate service?

Bookkeeping can be included as part of selected accounting packages or provided as a separate service, depending on your company’s requirements. IBS can help maintain your financial records and ensure your accounts are properly organised for reporting and tax compliance.

What is TRC?

TRC (Tax Residency Certificate) is an official document used to confirm that a company or individual is a tax resident of a particular country for tax purposes. It may be required when claiming benefits under a Double Taxation Agreement (DTA/DTAA).

What is DTAA?

DTAA (Double Tax Avoidance Agreement) is an agreement between two countries designed to prevent the same income from being taxed twice. It may provide tax relief, exemptions, or reduced withholding tax rates where the applicable conditions are met.
