Singapore GST registration: when and how to register

Goods and Services Tax (GST) may apply to supplies of goods and services in Singapore. Registration rules and administrative requirements can change. Use current Inland Revenue Authority of Singapore (IRAS) guidance and advice appropriate to your circumstances before acting.

The compulsory registration threshold

IRAS applies compulsory-registration tests based on taxable turnover and the relevant assessment period. Confirm the current tests, thresholds, exceptions, and application deadline directly with IRAS rather than relying on a static summary.

Should you register voluntarily?

Voluntary registration may be available subject to IRAS conditions. It can affect pricing, record-keeping, returns, input-tax claims, and the period for which a business must remain registered. Review the current conditions with IRAS and a qualified adviser before applying.

How to register with IRAS

IRAS publishes the current application route, supporting-information requirements, and any learning or administrative conditions. If IRAS approves an application, follow the effective date and obligations stated in the authority notice.

Ongoing GST obligations

Registered businesses have continuing return, payment, invoicing, and record-keeping responsibilities. The accounting period and deadline depend on the applicable IRAS requirements, so confirm them through the current official guidance and notices issued to the business.

Getting it right

GST registration introduces continuing responsibilities. Consult current IRAS guidance and an appropriately qualified adviser for your circumstances; UpVue does not determine tax obligations, submit applications, or make filing decisions.
